MISCELLANEOUS - - - Auto-hinter support for Mongolian. - - - For distribution, `.tar.bz2' packages are replaced with `.tar.xz' - bundles. - - - The handling of the default character in PCF fonts as introduced - in version 2.10.0 was partially broken, causing premature abortion - of charmap iteration for many fonts. - - - If `FT_Set_Named_Instance' was called with the same arguments - twice in a row, the function returned an incorrect error code the - second time. - - - Direct rendering using FT_RASTER_FLAG_DIRECT crashed (bug - introduced in version 2.10.0). - - - Increased precision while computing OpenType font variation - instances. - - - The flattening algorithm of cubic Bezier curves was slightly - changed to make it faster.

IMPORTANT CHANGES - - - A bunch of new functions has been added to access and process - COLR/CPAL data of OpenType fonts with color-layered glyphs. - - FT_Palette_Data_Get - Retrieve color palette data. - FT_Palette_Select - Select and activate a color palette for color-layered - glyphs. - FT_Palette_Set_Foreground_Color - Set text foreground color for palette index 0xFFFF. - - FT_Get_Color_Glyph_Layer - Get color layers for a given glyph (using an interator - object). - - FT_Bitmap_Blend - Blend one bitmap onto another with a given color. - - - An experimental feature is the new behaviour of the - `FT_LOAD_COLOR' load flag for color-layered glyphs: Internally - it sets a flag so that if `FT_Render_Glyph' is called with - `FT_RENDER_MODE_NORMAL' (or `FT_Load_Glyph' with - `FT_LOAD_RENDER'), a default blending of the color glyph layers - will happen automatically for convenience. - - - As a GSoC 2018 project, Nikhil Ramakrishnan completely - overhauled and modernized the API reference. - - - II. MISCELLANEOUS - - - The logic for computing the global ascender, descender, and - height of OpenType fonts has been slightly adjusted for - consistency. - - . If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection' - field) in the `OS/2' table is set, use the `sTypo' fields in - `OS/2' unconditionally. - . Otherwise use the metrics data from the `hhea' table (if not - zero). - . Otherwise use the `sTypo' fields from the `OS/2' table (if not - zero). - . Otherwise use the `usWin' data from the `OS/2' table as a last - resort. - - Variable fonts will apply the `MVAR' deltas to whichever metrics - were picked. - - - `TT_Set_MM_Blend' could fail if call repeatedly with the same - arguments. - - - The precision of handling deltas in Variation Fonts has been - increased. The problem did only show up with multidimensional - designspaces. - - - New function `FT_Library_SetLcdGeometry' to set up the geometry - of LCD subpixels. - - - FreeType now uses the `defaultChar' property of PCF fonts to set - the glyph for the undefined character at glyph index 0 (as - FreeType already does for all other supported font formats). As - a consequence, the order of glyphs of a PCF font if accessed - with FreeType can be different now compared to previous - versions. - - This change doesn't affect PCF font access with cmaps. - - - `FT_Select_Charmap' has been changed to allow parameter value - `FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT - formats to access built-in cmaps that don't have a predefined - `FT_Encoding' value. - - - A previously reserved field in the `FT_GlyphSlotRec' structure - now holds the glyph index. - - - On Win32 platforms, the use of `_DLL' to build the library has - been replaced with `DLL_EXPORT' and `DLL_IMPORT'. - - - The usual round of fuzzer bug fixes to better reject malformed - fonts. - - - `FT_Outline_New_Internal' and `FT_Outline_Done_Internal' have - been removed. These two functions were public by oversight only - and were never documented. - - - A new function `FT_Error_String' returns descriptions of error - codes if configuration macro FT_CONFIG_OPTION_ERROR_STRINGS is - defined. - - - `FT_Set_MM_WeightVector' and `FT_Get_MM_WeightVector' are new - functions limited to Adobe MultiMaster fonts to directly set and - get the weight vector. - - - Support for Position Independent Code as needed by systems that - prohibit automatic address fixups, such as BREW, has been - removed. [Compilation with modern compilers that use flags like - `-fPIC' or `-fPIE' is not affected.] - - - The `ftdump' demo program has new options `-c' and `-C' to - display charmaps in compact and detailed format, respectively. - Option `-V' has been removed. - - - The `ftview', `ftstring', and `ftgrid' demo programs use a new - command line option `-d' to specify the program window's width, - height, and color depth. - - - The `ftview' demo program now displays red boxes for zero-width - glyphs. - - - `ftglyph' has limited support to display fonts with - color-layered glyphs. This will be improved later on. - - - `ftgrid' can now display bitmap fonts also. - - - The `ttdebug' demo program has a new option `-f' to select a - member of a TrueType collection (TTC). - - - Other various improvements to the demo programs. - - -====================================================================== - -CHANGES BETWEEN 2.9 and 2.9.1 (2019-May-01) - - I. IMPORTANT BUG FIXES - - - Type 1 fonts containing flex features were not rendered - correctly (bug introduced in version 2.9). - - - CVE-2018-6942: Older FreeType versions can crash with certain - malformed variation fonts. - - https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6942 - - - II. MISCELLANEOUS - - - Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage. - - - The base extensions `ftlcdfil' and `ftfntfmt' are now part of - the base module (and thus no longer configurable in file - `modules.cfg'). - - - Emboldening of bitmaps didn't work correctly sometimes, showing - various artifacts (bug introduced in version 2.8.1). - - - Use of the `freetype-config' script to get compilation and - linking options is deprecated since it doesn't support - cross-compiling, among other deficiencies. Instead, you should - use the `pkg-config' interface. - - The `configure' script no longer installs `freetype-config' by - default. For backward compatibility, a new configure option - `--enable-freetype-config' is provided that reverts this - decision. - - - The auto-hinter script ranges have been updated for Unicode 11. - No support for new scripts have been added, however, with the - exception of Georgian Mtavruli. - - - Support for cmake has been improved. - - - The next release will remove support for Position Independent - Code as needed by systems that prohibit automatic address - fixups, such as BREW. [Compilation with modern compilers that - use flags like `-fPIC' or `-fPIE' is not affected.] - - -====================================================================== - -CHANGES BETWEEN 2.8.1 and 2.9 (2018-Jan-08) - - I. IMPORTANT BUG FIXES - - - Advance width values of variation fonts were often wrong. - - - More fixes for variation font support; you should update to this - version if you want to support them. - - - II. IMPORTANT CHANGES - - - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine - to handle Type 1 fonts also, thus greatly improving the - rendering of this format. This is the new default. The old - engine is still available if the configuration macro - `T1_CONFIG_OPTION_OLD_ENGINE' gets defined; using the - `hinting-engine' property of the `type1' driver module you can - then switch between the two engines. - - - A new function, `FT_Set_Named_Instance', can be used to set or - change the current named instance. - - - Starting with this FreeType version, resetting variation - coordinates will return to the currently selected named - instance. Previously, FreeType returned to the base font (i.e., - no instance set). - - - III. MISCELLANEOUS - - - The `face_flags' field of the `FT_Face' structure has a new bit, - `FT_FACE_FLAG_VARIATION', which is set if a variation font has - been altered with `FT_Set_MM_Design_Coordinates', - `FT_Set_Var_Design_Coordinates', or - `FT_Set_Var_Blend_Coordinates'. - - - If the current face is a named instance, the new macro - `FT_IS_NAMED_INSTANCE' returns true. - - - `FT_IS_VARIATION' is a new macro that returns true whenever a - face object has been altered by `FT_Set_MM_Design_Coordinates', - `FT_Set_Var_Design_Coordinates', or - `FT_Set_Var_Blend_Coordinates'. - - - Changing the design coordinates of a variation font with - `FT_Set_Var_Design_Coordinates' or - `FT_Set_Var_Blend_Coordinates' does not influence the named - instance index value (only `FT_Set_Named_Instance' does that). - - - Special PostScript names for named instances are only returned - if the named instance is set with `FT_Set_Named_Instance' (and - the font has corresponding entries in its `fvar' table). If - `FT_IS_VARIATION' returns true, the algorithmically derived - PostScript name is provided, not looking up special entries for - named instances. - - - A new function `FT_Done_MM_Var' is provided to free the memory - returned in a call to `FT_Get_MM_Var'. - - - On platforms using the `configure' script, the installed - `ftoption.h' file now correctly reflects configuration options - like `--with-harfbuzz'. - - - Better support to build FreeType as a DLL on Windows using - Visual C. - - - All data specific to driver modules is now collected in a single - file, `FT_DRIVER_H'. Consequently, the macros - `FT_AUTOHINTER_H', `FT_CFF_DRIVER_H', `FT_TRUETYPE_DRIVER_H', - and `FT_PCF_DRIVER_H' still work but are deprecated. - - - Some fuzzer fixes to better reject malformed fonts. - - - The `ftbench' demo program has a new test for opening a new face - and loading some glyphs. - - - The `ftbench' demo program has a new option `-j' to specify the - last glyph index to be used in the tests. - - - The `ftgrid' demo program has a new option `-n' to suppress - display of named instances of variation fonts. - - - The `ttdebug' demo program can now show a stack trace (key `K') - and switch between hexadecimal and decimal display of integers - (key `I'). - - -====================================================================== - -CHANGES BETWEEN 2.8 and 2.8.1 (2017-Sep-16) - - I. IMPORTANT BUG FIXES - - - B/W hinting of TrueType fonts didn't work properly if - interpreter version 38 or 40 was selected. - - - Some severe problems within the handling of TrueType Variation - Fonts were found and fixed. - - - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle - the case with less input coordinates than axes. - - - II. IMPORTANT CHANGES - - - By default, FreeType now offers high quality LCD-optimized - output without resorting to ClearType techniques of resolution - tripling and filtering. In this method, called Harmony, each - color channel is generated separately after shifting the glyph - outline, capitalizing on the fact that the color grids on LCD - panels are shifted by a third of a pixel. This output is - indistinguishable from ClearType with a light 3-tap filter. - - - III. MISCELLANEOUS - - - Using the new function `FT_Get_Var_Axis_Flags', an application - can access the `flags' field of a variation axis (introduced in - OpenType version 1.8.2) - - - More sanity checks. - - - The internal representation of buffers for LCD rendering has - changed (to be more precise, the amount of padding gets computed - differently). Applications that use the FreeType API are not - affected. - - - To reset all design axis values of a variation font to its - default values you can now say - - error = FT_Set_Var_Design_Coordinates( face, 0, NULL ); - - This also works with functions `FT_Set_MM_Design_Coordinates' - and `FT_Set_MM_Blend_Coordinates'. - - - FreeType now synthesizes a missing Unicode cmap for (older) - TrueType fonts also if glyph names are available. - - - FreeType has improved handling of BDF fonts without the - `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties; the - library now uses the values of the `SIZE' keyword if they are - missing. Previously, `SIZE' was completely ignored, and - FreeType used heuristic values instead. - - - Multiple calls to `FT_Bitmap_Convert' do work now as advertised. - Previously, they failed with an assertion error if there was an - empty bitmap between non-empty ones. - - - The warping option has moved from `light' to `normal' hinting - where it replaces the original hinting algorithm. The `light' - mode is now always void of any hinting in x-direction. - - - 16bit compiler support is now officially ended. We didn't - provide any maintenance since many years, and given that there - were no error or problem reports either it seems that it is no - longer needed. - - - The `ftgrid' demo program can now toggle the display of grid - lines with the `G' key. - - - The `ftgrid' demo program can toggle a different set of colors - (suitable to color-blind people) with the `C' key. - - - The `ftgrid' demo program now supports the `-e' command line - option to select a cmap. - - - The `ftdump' demo program has a new command line option `-t' to - output the SFNT table list. - - -====================================================================== - -CHANGES BETWEEN 2.7.1 and 2.8 (2017-May-13) - - I. IMPORTANT CHANGES - - - Support for OpenType Variation Fonts is now complete. The last - missing part was handling the `VVAR' and `MVAR' tables, which is - available with this release. - - - A new function `FT_Face_Properties' allows the control of some - module and library properties per font. Currently, the - following properties can be handled: stem darkening, LCD filter - weights, and the random seed for the `random' CFF operator. - - - The PCF change to show more `colorful' family names (introduced - in version 2.7.1) was too radical; it can now be configured with - PCF_CONFIG_OPTION_LONG_FAMILY_NAMES at compile time. If - activated, it can be switched off at run time with the new pcf - property `no-long-family-names'. If the `FREETYPE_PROPERTIES' - environment variable is available, you can say - - FREETYPE_PROPERTIES=pcf:no-long-family-names=1 - - - Support for the following scripts has been added to the - auto-hinter. - - Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot, - Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old - Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai - Viet, Tifinagh, Unified Canadian Syllabics, Vai - - - II. IMPORTANT BUG FIXES - - - `Light' auto-hinting mode no longer uses TrueType metrics for - TrueType fonts. This bug was introduced in version 2.4.6, - causing horizontal scaling also. Almost all GNU/Linux - distributions (with Fedora as a notable exception) disabled the - corresponding patch for good reasons; chances are thus high that - you won't notice a difference. - - If optical backward compatibility for legacy applications is - necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS - configuration option. However, it is strongly recommended to - avoid that, adjusting font sizes instead. - - - Global size metrics values in the `FT_Size_Metrics' structure - can be different for TrueType fonts. Reason is that in older - FreeType versions the metrics were rounded differently to - integer pixels compared to all other font formats, yielding an - inconsistent behaviour if you used non-native hinting. Starting - with this version, global size metrics for TrueType fonts are - handled the same as other font formats: `ascender' gets rounded - up, `descender' gets rounded down, `height' gets normally - rounded, and `max_advance' gets normally rounded, too. - - If you need more precise values of (global) ascender, descender, - height, or `max_advance', please take the corresponding values - from the `FT_Face' structure and scale them manually. - - - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType - now scales the font linearly again (bug introduced in version - 2.4.6). - - - CVE-2017-8105, CVE-2017-8287: Older FreeType versions have - out-of-bounds writes caused by heap-based buffer overflows - related to Type 1 fonts. - - https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105 - https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287 - - - III. MISCELLANEOUS - - - A new function `FT_Set_Default_Properties' has been added to - parse the `FREETYPE_PROPERTIES' environment variable - (previously, it was internal only). `FT_Init_FreeType' always - call this function, but `FT_New_Library' does not (similar to - `FT_Add_Default_Modules'). - - - To be in sync with OpenType version 1.7 and newer, macros - - FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY, - FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY, - TT_NAME_ID_PREFERRED_FAMILY - TT_NAME_ID_PREFERRED_SUBFAMILY - - are renamed to - - FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY, - FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY, - TT_NAME_ID_TYPOGRAPHIC_FAMILY - TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY - - The old macro names are deprecated (but still available). - - - Support for SFNT `name' tables has been improved. - - . Format 1 `name' tables are now supported. Use new function - `FT_Get_Sfnt_LangTag' to access associated language tags. - - . Language, encoding, and name IDs have been updated to OpenType - version 1.8.1. - - - The new CFF engine now handles the `random' operator. All CFF - opcodes are now supported. - - - The CFF module has a new property `random-seed' to control the - pseudo-random number generation for the `random' operator. - - - The `freetype-config' script is now a wrapper of `pkg-config' if - this program is available in the path. - - - FT_LOAD_TARGET_LCD is now a variant of FT_LOAD_TARGET_LIGHT; - this should provide better rendering results. - - - A mode to display light auto-hinting with subpixel positioning - has been added to `ftdiff'. - - -====================================================================== - -CHANGES BETWEEN 2.7 and 2.7.1 (2016-Dec-30) - - I. IMPORTANT CHANGES - - - Support for the new CFF2 font format as introduced with OpenType - 1.8 has been contributed by Dave Arnolds from Adobe. - - - Preliminary support for variation fonts as specified in OpenType - 1.8 (in addition to the already existing support for Adobe's MM - and Apple's GX formats). Dave Arnolds contributed handling of - advance width change variation; more will come in the next - version. - - - II. IMPORTANT BUG FIXES - - - Handling of raw CID fonts was partially broken (bug introduced - in 2.6.4). - - - CVE-2016-10328: Older FreeType versions had an out-of-bounds - write caused by a heap-based buffer overflow related to the CFF - fonts. - - https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10328 - - - III. MISCELLANEOUS - - - Some limits for TrueType bytecode execution have been tightened - to speed up FreeType's handling of malformed fonts, in - particular to quickly abort endless loops. - - - The number of twilight points can no longer be set to an - arbitrarily large value. - - - The total number of jump opcode instructions (like JMPR) with - negative arguments is dynamically restricted; the same holds - for the total number of iterations in LOOPCALL opcodes. - - The dynamic limits are based on the number of points in a glyph - and the number of CVT entries. Please report if you encounter a - font where the selected values are not adequate. - - - PCF family names are made more `colorful'; they now include the - foundry and information whether they contain wide characters. - For example, you no longer get `Fixed' but rather `Sony Fixed' - or `Misc Fixed Wide'. - - - A new function `FT_Get_Var_Blend_Coordinates' (with its alias - name `FT_Get_MM_Blend_Coordinates') to retrieve the normalized - blend coordinates of the currently selected variation instance - has been added to the Multiple Masters interface. - - - A new function `FT_Get_Var_Design_Coordinates' to retrieve the - design coordinates of the currently selected variation instance - has been added to the Multiple Masters interface. - - - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap - information without loading the (embedded) bitmap itself. - - - Retrieving advance widths from bitmap strikes (using - `FT_Get_Advance' and `FT_Get_Advances') have been sped up. - - - The usual round of fuzzer fixes to better reject malformed - fonts. - - - The `ftmulti' demo program can now switch engines with key `H'. - - - The `ftstring' demo program can now show some built-in, - non-latin sample strings (to be selected with the TAB key). - - - The `ftview' demo program can now switch between a font's - charmaps using the TAB key. - - -====================================================================== - -CHANGES BETWEEN 2.6.5 and 2.7 (2016-Sep-08) - - I. IMPORTANT CHANGES - - - As announced earlier, the 2.7.x series now uses the new subpixel - hinting mode as the default, emulating a modern version of - ClearType. - - This change inevitably leads to different rendering results, and - you might change the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' - configuration option to adapt it to your taste (or use the new - `FREETYPE_PROPERTIES' environment variable). See the - corresponding entry below for version 2.6.4, which gives more - information. - - - A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been - introduced. If set (which is the default), an environment - variable `FREETYPE_PROPERTIES' can be used to control driver - properties. Example: - - FREETYPE_PROPERTIES=truetype:interpreter-version=35 \ - cff:no-stem-darkening=1 \ - autofitter:warping=1 - - This allows to select, say, the subpixel hinting mode at runtime - for a given application. See file `ftoption.h' for more. - - - II. IMPORTANT BUG FIXES - - - After loading a named instance of a GX variation font, the - `face_index' value in the returned `FT_Face' structure now - correctly holds the named instance index in the upper 16bits as - documented. - - - III. MISCELLANEOUS - - - A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face - is a named instance. - - - More fixes to GX font handling. - - - Apple's `GETVARIATION' bytecode operator (needed for GX - variation font support) has been implemented. - - - Another round of fuzzer fixes, mainly to reject invalid fonts - faster. - - - Handling of raw CID fonts was broken (bug introduced in version - 2.6.4). - - - The smooth rasterizer has been streamlined to make it faster by - approx. 20%. - - - The `ftgrid' demo program now understands command line option - `-d' to give start-up design coordinates. - - - The `ftdump' demo program has a new command line option `-p' to - dump TrueType bytecode instructions. - - -====================================================================== - -CHANGES BETWEEN 2.6.4 and 2.6.5 (2016-Jul-12) - - I. IMPORTANT BUG FIXES - - - Compilation works again on Mac OS X (bug introduced in version - 2.6.4). - - - II. IMPORTANT CHANGES - - - The new subpixel hinting mode is now disabled by default; it - will be enabled by default in the forthcoming 2.7.x series. - Main reason for reverting this feature is the principle of least - surprise: a sudden change in appearance of all fonts (even if - the rendering improves for almost all recent fonts) should not - be expected in a new micro version of a series. - - -====================================================================== - -CHANGES BETWEEN 2.6.3 and 2.6.4 (2016-Jul-05) - - I. IMPORTANT CHANGES - - - A new subpixel hinting mode has been contributed by Nikolaus - Waxweiler, which is now the default rendering mode for TrueType - fonts. It implements (almost everything of) version 40 of the - bytecode engine. - - The existing code base in FreeType (the `Infinality code') was - stripped to the bare minimum and all configurability removed in - the name of speed and simplicity. The configurability was - mainly aimed at legacy fonts like Arial, Times New Roman, or - Courier. [Legacy fonts are fonts that modify vertical stems to - achieve clean black-and-white bitmaps.] The new mode focuses on - applying a minimal set of rules to all fonts indiscriminately so - that modern and web fonts render well while legacy fonts render - okay. - - Activation of the subpixel hinting support can be controlled - with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration - option at compile time: If set to value 1, you get the old - Infinality mode (which was never the default due to its - slowness). Value 2 activates the new subpixel hinting mode, and - value 3 activates both. The default is value 2. - - At run time, you can select the subpixel hinting mode with the - `interpreter-version' property (provided you have compiled in - the corresponding hinting mode); see `ftttdrv.h' for more. - - - Support for the following scripts has been added to the - auto-hinter. - - Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi, - Malayalam, Sinhala, Tamil - - - II. MISCELLANEOUS - - - Type 42 fonts as created by LilyPond are now supported. - - - Minor rendering improvements in the auto-hinter. - - - For experimental reasons, the old CFF engine now supports all - CFF operators except `random', including the deprecated Multiple - Masters instructions. This allows the display of fonts like - `ITCGaramondMM-It.otf' (without font variations, though). - - - Another round of fixes to improve handling of invalid fonts. - - - The `ftgrid' demo program now displays the rendered pixels also; - this can be switched off with the `b' key. Selection of various - LCD filtering modes can be done with the `L' key. - - - The demo programs have been extended to allow selection of all - available TrueType bytecode engines. - - - A very early beta version of a new, Qt based demo program called - `ftinspect' is part of the source code bundle; it will - eventually supersede the other demo programs. Currently, you - have to compile it manually with `qmake; make'; note that many - features are still missing. - - -====================================================================== - -CHANGES BETWEEN 2.6.2 and 2.6.3 (2016-Feb-08) - - I. IMPORTANT CHANGES - - - Khmer, Myanmar, Bengali, and Kannada script support has been - added to the auto-hinter. - - - II. MISCELLANEOUS - - - Better support of Indic scripts like Devanagari by using a - top-to-bottom hinting flow. - - - All FreeType macros starting with two underscores have been - renamed to avoid a violation of both the C and C++ standards. - Example: Header macros of the form `__FOO_H__' are now called - `FOO_H_'. In most cases, this should be completely transparent - to the user. The exception to this is `__FTERRORS_H__', which - must be sometimes undefined by the user to get FreeType error - strings: Both this form and the new `FTERRORS_H_' macro are - accepted for backward compatibility. - - - Minor improvements mainly to the Type 1 driver. - - - The new CFF engine now supports all Type 2 operators except - `random'. - - - The macro `_STANDALONE_', used for compiling the B/W and smooth - rasterizers as stand-alone modules, has been renamed to - `STANDALONE_', since macro names starting with an underscore and - followed by an uppercase letter are reserved in both C and C++. - - - Function `FT_Library_SetLcdFilterWeights' now also activates - custom LCD filter weights (instead of just adjusting them). - - - Support for `unpatented hinting' has been completely removed: - Consequently, the two functions `FT_Face_CheckTrueTypePatents' - and `FT_Face_SetUnpatentedHinting' now return always false, - doing nothing. - - - The `ftgamma' demo program has been modernized; the gamma grid - display has been moved from `ftview' to this program. - - - In `ftview', it is now possible to cycle through the available - LCD filtering modes. - - -====================================================================== - -CHANGES BETWEEN 2.6.1 and 2.6.2 (2015-Nov-28) - - I. IMPORTANT CHANGES - - - The auto-hinter now supports stem darkening, to be controlled by - the new `no-stem-darkening' and `darkening-parameters' - properties. This is an experimental feature contributed by - Nikolaus Waxweiler, and the interface might change in a future - release. - - - By default, stem darkening is now switched off (for both the CFF - engine and the auto-hinter). The main reason is that you need - linear alpha blending and gamma correction to get correct - rendering results, and the latter is not yet available in most - freely available rendering stacks like X11. Applying stem - darkening without proper gamma correction leads to far too dark - rendering results. - - - The meaning of `FT_RENDER_MODE_LIGHT' has been slightly - modified. It now essentially means `no hinting along the - horizontal axis'; in particular, no change of glyph advance - widths. Consequently, the auto-hinter is used for all scalable - font formats except for CFF. It is planned that other - font-specific rendering engines (TrueType, Type 1) will follow. - - - II. MISCELLANEOUS - - - The default LCD filter has been changed to be normalized and - color-balanced. - - - For better compatibility with FontConfig, function - `FT_Library_SetLcdFilter' accepts a new enumeration value - `FT_LCD_FILTER_LEGACY1' (which has the same meaning as - `FT_LCD_FILTER_LEGACY'). - - - A large number of bugs have been detected by using the libFuzzer - framework, which should further improve handling of invalid - fonts. Thanks again to Kostya Serebryany and Bungeman! - - - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES', a new configuration - option, controls the maximum number of executed opcodes within a - bytecode program. You don't want to change this except for very - special situations (e.g., making a library fuzzer spend less - time to handle broken fonts). - - - The smooth renderer has been made faster. - - - The `ftstring' demo program now supports subpixel rendering; use - key `l' to cycle through the LCD modes. - - - The `ftstring' demo program now supports color rendering; use - the `space' key to cycle through various color combinations. - - - The graphical demo programs now use a default gamma value of 1.8 - (instead of 1.2). - - -====================================================================== - -CHANGES BETWEEN 2.6 and 2.6.1 (2015-Oct-04) - - I. IMPORTANT BUG FIXES - - - It turned out that for CFFs only the advance widths should be - taken from the `htmx' table, not the side bearings. This bug, - introduced in version 2.6.0, makes it necessary to upgrade if - you are using CFFs; otherwise, you get cropped glyphs with GUI - interfaces like GTK or Qt. - - - Accessing Type 42 fonts returned incorrect results if the glyph - order of the embedded TrueType font differs from the glyph order - of the Type 42 charstrings table. - - - II. IMPORTANT CHANGES - - - The header file layout has been changed (again), moving all - header files except `ft2build.h' into a subdirectory tree. - - Doing so reduces the possibility of header file name clashes - (e.g., FTGL's `FTGlyph.h' with FreeType's `ftglyph.h') on case - insensitive file systems like Mac OS X or Windows. - - Applications that use (a) the `freetype-config' script or - FreeType's `freetype2.pc' file for pkg-config to get the include - directory for the compiler, and (b) the documented way for - header inclusion like - - #include - #include FT_FREETYPE_H - ... - - don't need any change to the source code. - - - Simple access to named instances in GX variation fonts is now - available (in addition to the previous method via FreeType's MM - interface). In the `FT_Face' structure, bits 16-30 of the - `face_index' field hold the current named instance index for the - given face index, and bits 16-30 of `style_flags' contain the - number of instances for the given face index. `FT_Open_Face' - and friends also understand the extended bits of the face index - parameter. - - You need to enable TT_CONFIG_OPTION_GX_VAR_SUPPORT for this new - feature. Otherwise, bits 16-30 of the two fields are zero (or - are ignored). - - - Lao script support has been added to the auto-hinter. - - - III. MISCELLANEOUS - - - The auto-hinter's Arabic script support has been enhanced. - - - Superscript-like and subscript-like glyphs as used by various - phonetic alphabets like the IPA are now better supported by the - auto-hinter. - - - The TrueType bytecode interpreter now runs slightly faster. - - - Improved support for builds with cmake. - - - The function `FT_CeilFix' now always rounds towards plus - infinity. - - - The function `FT_FloorFix' now always rounds towards minus - infinity. - - - A new load flag `FT_LOAD_COMPUTE_METRICS' has been added; it - makes FreeType ignore pre-computed metrics, as needed by font - validating or font editing programs. Right now, only the - TrueType module supports it to ignore data from the `hdmx' - table. - - - Another round of bug fixes to better handle broken fonts, found - by Kostya Serebryany . - - -====================================================================== - -CHANGES BETWEEN 2.5.5 and 2.6 (2015-Jun-07) - - I. IMPORTANT CHANGES - - - Behdad Esfahbod contributed code for improved thread-safety, - which results in the following model. - - * An `FT_Face' object can only be safely used from one thread at - a time. - - * An `FT_Library' object can now be used without modification - from multiple threads at the same time. - - * `FT_Face' creation and destruction with the same `FT_Library' - object can only be done from one thread at a time. - - One can use a single `FT_Library' object across threads as long - as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'. - Any calls to `FT_Load_Glyph' and similar API are safe and do not - need the lock to be held as long as the same `FT_Face' is not - used from multiple threads at the same time. - - - Thai script support has been added to the auto-hinter. - - - Arabic script support has been added to the auto-hinter. - - - Following OpenType version 1.7, advance widths and side bearing - values in CFFs (wrapped in an SFNT structure) are now always - taken from the `hmtx' table. - - - Following OpenType version 1.7, the PostScript font name of a - CFF font (wrapped in an SFNT structure) is now always taken from - the `name' table. This is also true for OpenType Collections - (i.e., TTCs using CFFs subfonts instead of TTFs), where it may - have a significant difference. - - - Fonts natively hinted for ClearType are now supported, properly - handling selector index 3 of the INSTCTRL bytecode instruction. - - - Major improvements to the GX TrueType variation font handling. - - - II. MISCELLANEOUS - - - A new auto-hinter property `warping' can switch on and off the - warping code if this experimental feature is compiled in (by - defining the AF_CONFIG_OPTION_USE_WARPER configuration option; - by default this option is now enabled but warping is switched - off). - - The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature, - available since 2006. Warping only works in `light' - auto-hinting mode. The idea of the code is to slightly scale - and shift a glyph along the non-hinted dimension (which is - usually the horizontal axis) so that as much of its segments are - aligned (more or less) to the grid. To find out a glyph's - optimal scaling and shifting value, various parameter - combinations are tried and scored. - - See file `ftautoh.h' for more; the demo programs `ftdiff', - `ftview', and `ftgrid' can toggle warping with key `w'. - - - Some fields in the `FTC_ImageTypeRec' structure have been - changed from signed to unsigned type, which better reflects the - actual usage. It is also an additional means to protect against - malformed input. - - This change doesn't break the ABI; however, it might cause - compiler warnings. - - - Function `FT_Bitmap_New' has been renamed to `FT_Bitmap_Init', - since this name better reflects its function. For backward - compatibility, the old function name is still available. - - - Function `FT_Get_X11_Font_Format' has been renamed to - `FT_Get_Font_Format', since this name better reflects its - function. For backward compatibility, the old function name is - still available. - - Additionally, the header file macro for this function has been - renamed to `FT_FONT_FORMATS_H' (the old name `FT_XFREE86_H' is - retained for backward compatibility). - - - Various improvements to the `ftgrid' demo program. - - . It can now display GX and MM fonts while interactively - manipulating the axes (with keys F2, F3, and F4). - - . Anti-aliasing rendering modes can now be selected (with keys - F5 and F6). - - . The display of point numbers can be toggled with key `D'. - - - Various improvements to the `ftdump' demo program. - - . It now displays information on MM and GX variation axes. - - . New command line option `-u' makes it output data in utf-8 - encoding. - - - The `ftmulti' demo program can now handle up to six MM or GX - axes. - - -====================================================================== - -CHANGES BETWEEN 2.5.4 and 2.5.5 (2014-Dec-30) - - I. IMPORTANT BUG FIXES - - - Handling of uncompressed PCF files works again (bug introduced - in version 2.5.4). - - -====================================================================== - -CHANGES BETWEEN 2.5.3 and 2.5.4 (2014-Dec-06) - - I. IMPORTANT BUG FIXES - - - A variant of vulnerability CVE-2014-2240 was identified - (cf. https://savannah.nongnu.org/bugs/?43661) and fixed in the - new CFF driver. All users should upgrade. - - - The new auto-hinter code using HarfBuzz crashed for some invalid - fonts. - - - Many fixes to better protect against malformed input. - - - II. IMPORTANT CHANGES - - - Full auto-hinter support of the Devanagari script. - - - Experimental auto-hinter support of the Telugu script. - - - CFF stem darkening behaviour can now be controlled at build time - using the eight macros - - CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4} . - - - Some fields in the `FT_Bitmap' structure have been changed from - signed to unsigned type, which better reflects the actual usage. - It is also an additional means to protect against malformed - input. - - This change doesn't break the ABI; however, it might cause - compiler warnings. - - - III. MISCELLANEOUS - - - Improvements to the auto-hinter's algorithm to recognize stems - and local extrema. - - - Function `FT_Get_SubGlyph_Info' always returned an error even in - case of success. - - - Version 2.5.1 introduced major bugs in the cjk part of the - auto-hinter, which are now fixed. - - - The `FT_Sfnt_Tag' enumeration values have been changed to - uppercase, e.g. `FT_SFNT_HEAD'. The lowercase variants are - deprecated. This is for orthogonality with all other - enumeration (and enumeration-like) values in FreeType. - - - `cmake' now supports builds of FreeType as an OS X framework and - for iOS. - - - Improved project files for vc2010, introducing a property file. - - - The documentation generator for the API reference has been - updated to produce better HTML code (with proper CSS). At the - same time, the documentation got a better structure. - - - The FT_LOAD_BITMAP_CROP flag is obsolete; it is not used by any - driver. - - - The TrueType DELTAP[123] bytecode instructions now work in - subpixel hinting mode as described in the ClearType whitepaper - (i.e., for touched points in the non-subpixel direction). - - - Many small improvements to the internal arithmetic routines. - - -====================================================================== - -CHANGES BETWEEN 2.5.2 and 2.5.3 (2014-Mar-06) - - I. IMPORTANT BUG FIXES - - - A vulnerability (CVE-2014-2240) was identified and fixed in the - new CFF driver (cf. https://savannah.nongnu.org/bugs/?41697). - All users should upgrade. - - - More bug fixes related to correct positioning of composite - glyphs. - - - Many fixes to better protect against malformed input. - - - II. IMPORTANT CHANGES - - - FreeType can now use the HarfBuzz library to greatly improve the - auto-hinting of fonts that use OpenType features: Many glyphs - that are part of such features but don't have cmap entries are - now handled properly, for example small caps or superscripts. - Define the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ to - activate HarfBuzz support. - - You need HarfBuzz version 0.9.19 or newer. - - Note that HarfBuzz depends on FreeType; this currently causes a - chicken-and-egg problem that can be solved as follows in case - HarfBuzz is not yet installed on your system. - - 1. Compile and install FreeType without the configuration - macro FT_CONFIG_OPTION_USE_HARFBUZZ. - - 2. Compile and install HarfBuzz. - - 3. Define macro FT_CONFIG_OPTION_USE_HARFBUZZ, then compile - and install FreeType again. - - With FreeType's `configure' script the procedure boils down to - configure, build, and install FreeType, then configure, compile, - and install HarfBuzz, then configure, compile, and install - FreeType again (after executing `make distclean'). - - - All libraries FreeType depends on are now checked using the - `pkg-config' configuration files first, followed by alternative - methods. - - - The new value `auto' for the various `--with-XXX' library - options (for example `--with-harfbuzz=auto') makes the - `configure' script automatically link to the libraries it finds. - This is now the default. - - - In case FreeType's `configure' script can't find a library, you - can pass environment variables to circumvent pkg-config, and - those variables have been harmonized as a consequence of the - changes mentioned above: - - LIBZ -> removed; use LIBZ_CFLAGS and LIBZ_LIBS - LIBBZ2 -> removed; use BZIP2_CFLAGS and BZIP2_LIBS - LIBPNG_LDFLAGS -> LIBPNG_LIBS - - `./configure --help' shows all available environment variables. - - - The `freetype-config' script now understands option `--static' - to emit static linking information. - - -====================================================================== - -CHANGES BETWEEN 2.5.1 and 2.5.2 (2013-Dec-08) - - I. IMPORTANT BUG FIXES - - - Improving the display of some broken TrueType fonts introduced a - bug that made FreeType crash on some popular (but not fully - conformant) fonts like `ahronbd.ttf'. - - - Another round of improvements to correct positioning and hinting - of composite glyphs in TrueType fonts. - - - II. MISCELLANEOUS - - - Version 2.5.1 introduced a bug in handling embedded bitmap - strikes of TrueType fonts, causing garbage display under some - circumstances. - - - The `ftgrid' demo program couldn't be compiled in - non-development builds. - - -====================================================================== - -CHANGES BETWEEN 2.5 and 2.5.1 (2013-Nov-25) - - I. IMPORTANT BUG FIXES - - - For some WinFNT files, the last glyph wasn't displayed but - incorrectly marked as invalid. - - - The vertical size of glyphs was incorrectly set after a call to - `FT_GlyphSlot_Embolden', resulting in clipped glyphs. - - - Many fields of the `PCLT' table in SFNT based fonts (if accessed - with `FT_Get_Sfnt_Table') were computed incorrectly. - - - In TrueType fonts, hinting of composite glyphs could sometimes - deliver incorrect positions of components or even distorted - shapes. - - - II. IMPORTANT CHANGES - - - WOFF font format support has been added. - - - The auto-hinter now supports Hebrew. Greek and Cyrillic support - has been improved. - - - Support for the forthcoming `OS/2' SFNT table version 5, as can - be found e.g. in the `Sitka' font family for Windows 8.1. - - - The header file layout has been changed. After installation, - all files are now located in `/include/freetype2'. - - Applications that use (a) `freetype-config' or FreeType's - `pkg-config' file to get the include directory for the compiler, - and (b) the documented way for header inclusion like - - #include - #include FT_FREETYPE_H - ... - - don't need any change to the source code. - - - III. MISCELLANEOUS - - - The stem darkening feature of the new CFF engine can now be - fine-tuned with the new `darkening-parameters' property. - - - `ftgrid' has been updated to toggle various engines with the `H' - key, similar to `ftview' and `ftdiff'. - - - The functionality of `ttdebug' has been greatly enhanced. - - . It now displays twilight, storage, and control value data; key - `T' shows the twilight point table, key `S' the storage data, - and key `C' the control value table. - - . Some keys have been reassigned from lowercase to their - uppercase equivalents; for example `q' to quit the program is - now `Q'. - - . Key `f' finishes the current function. - - . Key `R' restarts the debugger. - - . Keys `b' and `p' set a breakpoint. - - . Key `B' provides a function call backtrace. - - - Better support of ARMv7 and x86_64 processors. - - - Apple's `sbix' color bitmap format is now supported. - - - Improved auto-hinter rendering for many TrueType fonts, - especially in the range 20-40ppem. - - - A new face flag `FT_FACE_FLAG_COLOR' has been added (to be - accessed with the macro `FT_HAS_COLOR'). - - - `FT_Gzip_Uncompress' (modeled after zlib's `uncompress' - function) has been added; this is a by-product of the newly - added WOFF support. - - - Support for a build with `cmake' has been contributed by John - Cary . - - - Support for x64 builds with Visual C++ has been contributed by - Kenneth Miller - - - Manual pages for most demo programs have been added. - - - The GETINFO bytecode instruction for TrueType fonts was buggy if - used to retrieve subpixel hinting information. It was necessary - to set selector bit 6 to get results for selector bits 7-10, - which is wrong. - - - Improved computation of emulated vertical metrics for TrueType - fonts. - - - Fixed horizontal start-up position of vertical phantom points in - TrueType bytecode. - - -====================================================================== - -CHANGES BETWEEN 2.4.12 and 2.5 (2013-Jun-19) - - I. IMPORTANT BUG FIXES - - - The cache manager function `FTC_Manager_Reset' didn't flush the - cache. - - - II. IMPORTANT CHANGES - - - Behdad Esfahbod (on behalf of Google) contributed support for - color embedded bitmaps (eg. color emoji). - - A new load flag, FT_LOAD_COLOR, makes FreeType load color - embedded-bitmaps, following this draft specification - - https://color-emoji.googlecode.com/git/specification/v1.html - - which defines two new SFNT tables, `CBDT' and `CBLC' (named and - modeled after `EBDT' and `EBLC', respectively). The color - bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to - represent BGRA pre-multiplied sRGB images. If PNG support is - available, PNG color images as defined in the same proposed - specification are supported also. - - Note that color bitmaps are converted to grayscale if client - didn't ask for color. - - - As announced in the previous release, the old FreeType CFF - engine is now disabled by default. It can be conditionally - compiled by defining the configuration macro - CFF_CONFIG_OPTION_OLD_ENGINE. - - - As announced in the previous release, all code related to macro - FT_CONFIG_OPTION_OLD_INTERNALS has been removed, thus becoming - obsolete. - - - III. MISCELLANEOUS - - - The property API (`FT_Property_Get' and `FT_Property_Set') is - now declared as stable. - - The exception, however, are the experimental auto-hinter - properties `glyph-to-script-map' and `fallback-script' which are - subject to change in a forthcoming release. - - - `ftview' has been updated to support color embedded bitmaps; it - can be toggled on and off with key `c'. The small cache toggle - is now key `K'. - - - It is now possible to control the version of the TrueType - hinting engine using the new `interpreter-version' property of - the `truetype' module: Versions 35 and 38 (the default) are - supported, which roughly corresponds to disable and enable - subpixel hinting support, respectively. - - In both `ftview' and `ftdiff', switching between the two - versions can be done with key `H'. In the `ftbench' demo - program, command line option `-H' has been extended to activate - the non-default interpreter version. - - - The `ttdebug' program has been further improved. In particular, - it accepts a new command line option `-H' to select the hinting - engine. - - - `ftdump's verbose option has been renamed to `-V'. For all demo - programs, `-v' now shows version information. - - - Another round of TrueType subpixel hinting fixes. - - - The `apinames' tool can now create an import file for NetWare. - - - 64bit compilation of the new CFF engine was buggy. - - - Some fixes to improve robustness in memory-tight situations. - - -====================================================================== - -CHANGES BETWEEN 2.4.11 and 2.4.12 (2013-May-08) - - - We have another CFF parsing and hinting engine! Written by Dave - Arnold , this work has been contributed by - Adobe in collaboration with Google. It is vastly superior to - the old CFF engine, and it will replace it in the next release. - Right now, it is still off by default, and you have to - explicitly select it using the new `hinting-engine' property of - the cff driver: - - ... - #include FT_MODULE_H - #include FT_CFF_DRIVER_H - - FT_Library library; - int engine = FT_CFF_HINTING_ADOBE; - - - ... - FT_Property_Set( library, "cff", "hinting-engine", &engine ); - - The code has a (mature) beta status; we encourage all users to - test it and report any problems. - - In case you want to activate the new CFF engine unconditionally, - apply this patch: - ---- snip --- -diff --git a/src/cff/cffobjs.c b/src/cff/cffobjs.c -index ebcf189..3f2ce6b 100644 ---- a/src/cff/cffobjs.c -+++ b/src/cff/cffobjs.c -@@ -1056,7 +1056,7 @@ - - - /* set default property values */ -- driver->hinting_engine = FT_CFF_HINTING_FREETYPE; -+ driver->hinting_engine = FT_CFF_HINTING_ADOBE; - driver->no_stem_darkening = FALSE; - - return FT_Err_Ok; ---- snip --- - - - The macro FT_CONFIG_OPTION_OLD_INTERNALS is no longer set by - default. In the next release, we will completely remove the - associated code. Please update your programs in case you are - still using this macro. - - - II. MISCELLANEOUS - - - The (top-level) `configure' script now respects the MAKE - environment variable to specify a `make' binary. For backward - compatibility, GNUMAKE still overrides MAKE, though. - - - The `ftview' and `ftdiff' demo programs have been redesigned, - showing more options permanently on the screen, among other - minor improvements. - - - Using the `H' key, it is now possible to select the CFF engine - in both `ftview' and `ftdiff'. - - - The new command line option `-H' for `ftbench' selects the Adobe - CFF engine. - - - It is now possible to directly select the LCD rendering mode - with the keys `A'-`F' in `ftview'. The key mapping for cycling - through LCD modes has been changed from `K' and `L' to `k' and - `l', and toggling custom LCD filtering is no longer mapped to - key `F' but to key `L'. - - - In `ftdiff', key `x' toggles between layout modes: Either use - the advance width (this is new and now the default) or the - bounding box information to determine line breaks. - - - For all demo tools, the new command line option `-v' shows the - version. - - - For the demo tools with a GUI, the new command line options `-w' - and `-h' select the width and the height of the output window, - respectively. - - - The `ttdebug' program was broken and has been reactivated. Note - that this program is not compiled by default. - - -====================================================================== - -CHANGES BETWEEN 2.4.10 and 2.4.11 (2012-Dec-20) - - I. IMPORTANT BUG FIXES - - - Some vulnerabilities in the BDF implementation have been fixed. - Users of this font format should upgrade. - - - II. IMPORTANT CHANGES - - - Subpixel hinting support has been contributed by Infinality, - based on Greg Hitchcock's whitepaper at - - https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx - - Originally, it was a separate patch available from - - https://web.archive.org/web/20150710073951/http://www.infinality.net:80/blog/ - - and which has been integrated. - - Note that ClearType support is not completely implemented! In - particular, full support for the options `compatible_widths', - `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode - instruction) is missing. - - Activation of subpixel hinting support can be controlled with - the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it - is switched off by default. This feature is still experimental; - we welcome test reports! - - - Support for OpenType collections (OTC) has been added. - - - Pure CFF fonts within an SFNT wrapper are now supported. - - - III. MISCELLANEOUS - - - Minor rendering improvements to the auto-hinter. - - - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°. - - - Experimental support to handle `property modules', for example - to control the behaviour of the auto-hinter. The API consists - of two new functions, `FT_Property_Set' and `FT_Property_Get'. - - The code is still subject to change and should not be used for - production. - - - The `ftdiff' demo program now supports UTF-8 encoded input files - for option `-f'. - - - Using keys `r' and `R', you can now adjust the stroker radius in - the `ftview' demo program. - - - Other, minor fixes and improvements. - - -====================================================================== - -CHANGES BETWEEN 2.4.9 and 2.4.10 (2012-Jun-15) - - I. IMPORTANT BUG FIXES - - - Incremental glyph loading as needed by ghostscript was broken. - - - II. MISCELLANEOUS - - - A new function `FT_Outline_EmboldenXY', contributed by Alexei - Podtelezhnikov. - - - In the `ftview' demo program, key `e' has been replaced with `x' - and `y' to embolden in the horizontal and vertical direction, - respectively. - - - The glyph spacing computation in `FT_GlyphSlot_Embolden' (and - similar code in `ftview') has been improved. - - - Minor improvements to the TrueType bytecode interpreter and - glyph loader, the auto-hinter, and the B/W rasterizer. - - -====================================================================== - -CHANGES BETWEEN 2.4.8 and 2.4.9 (2012-Mar-08) - - I. IMPORTANT BUG FIXES - - - Another round of fixes to better handle invalid fonts. Many of - them are vulnerabilities (see CVE-2012-1126 up to CVE-2012-1144 - and SA48320) so all users should upgrade. - - - II. MISCELLANEOUS - - - The `ENCODING -1 ' format of BDF fonts is now supported. - - - For BDF fonts, support for the whole Unicode encoding range has - been added. - - - Better TTF support for x_ppem != y_ppem. - - - `FT_Get_Advances' sometimes returned bogus values. - - - The demo programs no longer recognize and handle default - suffixes; you now have to always specify the complete font name. - - - Better rendering and LCD mode cycling added to `ftview'. - - -====================================================================== - -CHANGES BETWEEN 2.4.7 and 2.4.8 (2011-Nov-14) - - I. IMPORTANT BUG FIXES - - - Some vulnerabilities in handling CID-keyed PostScript fonts have - been fixed; see CVE-2011-3439. - - - II. MISCELLANEOUS - - - Chris Liddell contributed a new API, `FT_Get_PS_Font_Value', to - retrieve most of the dictionary keys in Type 1 fonts. - - -====================================================================== - -CHANGES BETWEEN 2.4.6 and 2.4.7 (2011-Oct-18) - - I. IMPORTANT BUG FIXES - - - Some vulnerabilities in handling Type 1 fonts have been fixed; - see CVE-2011-3256. - - - II. MISCELLANEOUS - - - FreeType now properly handles ZapfDingbats glyph names while - constructing a Unicode character map (for fonts which don't have - one). - - -====================================================================== - -CHANGES BETWEEN 2.4.5 and 2.4.6 (2011-Jul-29) - - I. IMPORTANT BUG FIXES - - - For TrueType based fonts, the ascender and descender values were - incorrect sometimes (off by a pixel if the ppem value was not a - multiple of 5). Depending on the use you might now experience - a different layout; the change should result in better, more - consistent line spacing. - - - Fix CVE-2011-0226 which causes a vulnerability while handling - Type 1 fonts. - - - BDF fonts containing glyphs with negative values for ENCODING - were incorrectly rejected. This bug has been introduced in - FreeType version 2.2.0. - - - David Bevan contributed a major revision of the FreeType stroker - code: - - . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. - - . A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has - been introduced to support PostScript and PDF miter joins. - - . FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an - alias for FT_STROKER_LINEJOIN_MITER. - - . Various stroking glitches has been fixed. - - - II. MISCELLANEOUS - - - SFNT bitmap fonts which contain an outline glyph for `.notdef' - only no longer set the FT_FACE_FLAG_SCALABLE flag. - - -====================================================================== - -CHANGES BETWEEN 2.4.4 and 2.4.5 (2011-Jun-25) - - I. IMPORTANT BUG FIXES - - - A rendering regression for second-order Bézier curves has been - fixed, introduced in 2.4.3. - - - II. IMPORTANT CHANGES - - - If autohinting is not explicitly disabled, FreeType now uses - the autohinter if a TrueType based font doesn't contain native - hints. - - - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH has been made - redundant and is simply ignored; this means that FreeType now - ignores the global advance width value in TrueType fonts. - - - III. MISCELLANEOUS - - - `FT_Sfnt_Table_Info' can now return the number of SFNT tables of - a font. - - - Support for PCF files compressed with bzip2 has been contributed - by Joel Klinghed. To make this work, the OS must provide a - bzip2 library. - - - Bradley Grainger contributed project and solution files in - Visual Studio 2010 format. - - - Again some fixes to better handle broken fonts. - - - Some improvements to the B/W rasterizer. - - - Fixes to the cache module to improve robustness. - - - Just Fill Bugs contributed (experimental) code to compute blue - zones for CJK Ideographs, improving the alignment of horizontal - stems at the top or bottom edges. - - - The `ftgrid' demo program can now display autohinter segments, - to be toggled on and off with key `s'. - - -====================================================================== - -CHANGES BETWEEN 2.4.3 and 2.4.4 (2010-Nov-28) - - I. IMPORTANT BUG FIXES - - - UVS support (TrueType/OpenType cmap format 14) support is fixed. - This regression has been introduced in version 2.4.0. - - - II. MISCELLANEOUS - - - Detect tricky fonts (e.g. MingLiU) by the lengths and checksums - of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when - a TrueType font without family name is given. The previous fix, - introduced in 2.4.3, was too rigorous, causing many subsetted - fonts (mainly from PDF files) displayed badly because FreeType - forced rendering with the TrueType bytecode engine instead of - the autohinter. - - - Better support for 64bit platforms. - - - More fixes to improve handling of broken fonts. - - -====================================================================== - -CHANGES BETWEEN 2.4.2 and 2.4.3 (2010-Oct-03) - - I. IMPORTANT BUG FIXES - - - Fix rendering of certain cubic, S-shaped arcs. This regression - has been introduced in version 2.4.0. - - - II. MISCELLANEOUS - - - To fix the above mentioned rendering issue, a new spline - flattening algorithm has been introduced which speeds up both - conic and cubic arcs. - - - Handling of broken fonts has been further improved. - - -====================================================================== - -CHANGES BETWEEN 2.4.1 and 2.4.2 (2010-Aug-06) - - I. IMPORTANT BUG FIXES - - - A stack overflow in CFF Type2 CharStrings interpreter is fixed. - - - Handling Type 42 font deallocation was broken; additionally, the - library is now more robust against malformed Type 42 fonts. - - - II. MISCELLANEOUS - - - Two new functions, `FT_Reference_Library' (in FT_MODULE_H) and - `FT_Reference_Face' (in FT_FREETYPE_H), have been added to - simplify life-cycle management. A counter gets initialized to 1 - at the time an FT_Library (or FT_Face) structure is created. - The two new functions increment the respective counter. - `FT_Done_Library' and `FT_Done_Face' then only destroy a library - or face if the counter is 1, otherwise they simply decrement the - counter. - - -====================================================================== - -CHANGES BETWEEN 2.4.0 and 2.4.1 (2010-Jul-18) - - I. IMPORTANT CHANGES - - - A serious bug in the CFF font module prevented display of many - glyphs in CFF fonts like `MinionPro-Regular.otf'. - - -====================================================================== - -CHANGES BETWEEN 2.3.12 and 2.4.0 (2010-Jul-12) - - I. IMPORTANT CHANGES - - - Since May 2010, all patents regarding the TrueType bytecode - interpreter have expired worldwide. Consequently, we now define - TT_CONFIG_OPTION_BYTECODE_INTERPRETER by default (and undefine - TT_CONFIG_OPTION_UNPATENTED_HINTING). - - - A new function `FT_Library_SetLcdFilterWeights' is available to - adjust the filter weights set by `FT_Library_SetLcdFilter'. - - - II. MISCELLANEOUS - - - Thanks to many reports from Robert ÅšwiÄ™cki, FreeType's stability - in handling broken or damaged fonts is much improved. - - - Support for LCD filter control has been added to the demo - programs `ftdiff' and `ftview'. - - -====================================================================== - -CHANGES BETWEEN 2.3.11 and 2.3.12 - - I. IMPORTANT CHANGES - - - For `FT_Open_Face', new parameters are available to ignore - preferred family names: FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY and - FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY. - - - II. MISCELLANEOUS - - - Support for incremental font loading (controlled with the - FT_CONFIG_OPTION_INCREMENTAL macro) is now active by default. - - - Better support for vertical metrics. - - - Various minor bug fixes. - - -====================================================================== - -CHANGES BETWEEN 2.3.10 and 2.3.11 - - I. IMPORTANT BUG FIXES - - - Version 2.3.10 broke PCF support. - - -====================================================================== - -CHANGES BETWEEN 2.3.10 and 2.3.9 - - I. IMPORTANT BUG FIXES - - - If all ASCII digits in a font have the same (unscaled) width, - the autohinter respects this and won't change it. - - - TrueType fonts are now rasterized correctly if the horizontal - and vertical resolution differ. - - - Type 1 fonts are now handled with increased precision internally - to avoid serious rounding issues if non-integral coordinates are - encountered. - - - Horizontally condensed CFF fonts (using the font matrix) were - rendered incorrectly. This bug has been introduced after - release 2.3.5. - - - II. IMPORTANT CHANGES - - - Support for the SFNT cmap 13 table format (as defined by the new - OpenType 1.6 specification) has been added. - - - B/W rasterization of well-hinted TrueType fonts at small sizes - has been greatly improved. - - - Calculation of vertical metrics in OpenType fonts has been - improved. - - - III. MISCELLANEOUS - - - It is now possible to change the emboldening factor in the - `ftview' demo program with keys `e' and `E'. - - - It is now possible to change the slant value in the `ftview' - demo program with keys `s' and `S'. - - - The 5-levels grayscale mode of the `ftraster' module (which - FreeType doesn't use by default) was broken since version 2.3.0. - - - Compilation of the `ftgrays' and `ftraster' modules was broken - in stand-alone mode. - - - Various fixes for compilation on 64bit and 16bit architectures. - - -====================================================================== - -CHANGES BETWEEN 2.3.9 and 2.3.8 - - I. IMPORTANT BUG FIXES - - - Very unfortunately, FreeType 2.3.8 contained a change that broke - its official ABI. The end result is that programs compiled - against previous versions of the library, but dynamically linked - to 2.3.8 can experience memory corruption if they call the - `FT_Get_PS_Font_Info' function. - - We recommend all users to upgrade to 2.3.9 as soon as possible, - or to downgrade to a previous release of the library if this is - not an option. - - The origin of the bug is that a new field was added to the - publicly defined `PS_FontInfoRec' structure. Unfortunately, - objects of this type can be stack or heap allocated by callers - of `FT_Get_PS_Font_Info', resulting in a memory buffer - overwrite with its implementation in 2.3.8. - - If you want to know whether your code is vulnerable to this - issue, simply search for the substrings `PS_FontInfo' and - `PS_Font_Info' in your source code. If none is found, your code - is safe and is not affected. - - The FreeType team apologizes for the problem. - - - The POSIX support of MacOS resource-fork fonts (Suitcase fonts - and LaserWriter Type1 PostScript fonts) was broken in 2.3.8. If - FreeType2 is built without Carbon framework, these fonts are not - handled correctly. Version 2.3.7 didn't have this bug. - - - `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for - almost all font formats except TrueType fonts. - - - Fix a bug in the SFNT kerning table loader/parser which could - crash the engine if certain malformed tables were encountered. - - - Composite SFNT bitmaps are now handled correctly. - - - II. IMPORTANT CHANGES - - - The new functions `FT_Get_CID_Is_Internally_CID_keyed' and - `FT_Get_CID_From_Glyph_Index' can be used to access CID-keyed - CFF fonts via CID values. This code has been contributed by - Michael Toftdal. - - - III. MISCELLANEOUS - - - `FT_Outline_Get_InsideBorder' returns FT_STROKER_BORDER_RIGHT - for empty outlines. This was incorrectly documented. - - - The `ftview' demo program now supports UTF-8 encoded strings. - - -====================================================================== - -CHANGES BETWEEN 2.3.8 and 2.3.7 - - I. IMPORTANT BUG FIXES - - - CID-keyed fonts in an SFNT wrapper were not handled correctly. - - - The smooth renderer produced truncated images (on the right) for - outline parts with negative horizontal values. Most fonts don't - contain outlines left to the y coordinate axis, but the effect - was very noticeable for outlines processed with FT_Glyph_Stroke, - using thick strokes. - - - `FT_Get_TrueType_Engine_Type' returned a wrong value if both - configuration macros TT_CONFIG_OPTION_BYTECODE_INTERPRETER and - TT_CONFIG_OPTION_UNPATENTED_HINTING were defined. - - - The `face_index' field in the `FT_Face' structure wasn't - initialized properly after calling FT_Open_Face and friends with - a positive face index for CFFs, WinFNTs, and, most importantly, - for TrueType Collections (TTCs). - - - II. IMPORTANT CHANGES - - - Rudimentary support for Type 1 fonts and CID-keyed Type 1 fonts - in an SFNT wrapper has been added -- such fonts are used on the - Mac. The core SFNT tables `TYP1' and `CID ' are passed to the - PS Type 1 and CID-keyed PS font drivers; other tables (`ALMX', - `BBOX', etc.) are not supported yet. - - - A new interface to extract advance values of glyphs without - loading their outlines has been added. The functions are called - `FT_Get_Advance' and `FT_Get_Advances'; they are defined in file - `ftadvanc.h' (to be accessed as FT_ADVANCES_H). - - - A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been - contributed by David Bevan to access the embedding and - subsetting restriction information of fonts. - - - III. MISCELLANEOUS - - - FT_MulFix is now an inlined function; by default, assembler code - is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX - and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more. - - - The handling of `tricky' fonts (this is, fonts which don't work - with the autohinter, needing the font format's hinting engine) - has been generalized and changed slightly: - - . A new face flag FT_FACE_FLAG_TRICKY indicates that the font - format's hinting engine is necessary for correct rendering. - The macro FT_IS_TRICKY can be used to check this flag. - - . FT_LOAD_NO_HINTING is now ignored for tricky fonts. To really - force raw loading of such fonts (without hinting), both - FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used -- - this is something which you probably never want to do. - - . Tricky TrueType fonts always use the bytecode interpreter, - either the patented or unpatented version. - - - The function `FT_GlyphSlot_Own_Bitmap' has been moved from - FT_SYNTHESIS_H to FT_BITMAP_H; it is now part of the `official' - API. (The functions in FT_SYNTHESIS_H are still subject to - change, however.) - - - In the `ftdiff' demo program you can now toggle the use of - FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'. - - -====================================================================== - -CHANGES BETWEEN 2.3.7 and 2.3.6 - - I. IMPORTANT BUG FIXES - - - If the library was compiled on an i386 platform using gcc, and - compiler option -O3 was given, `FT_MulFix' sometimes returned - incorrect results which could have caused problems with - `FT_Request_Metrics' and `FT_Select_Metrics', returning an - incorrect descender size. - - - Pure CFFs without subfonts were scaled incorrectly if the font - matrix was non-standard. This bug has been introduced in - version 2.3.6. - - - The `style_name' field in the `FT_FaceRec' structure often - contained a wrong value for Type 1 fonts. This misbehaviour - has been introduced in version 2.3.6 while trying to fix - another problem. [Note, however, that this value is - informative only since the used algorithm to extract it is - very simplistic.] - - - II. IMPORTANT CHANGES - - - Two new macros, FT_OUTLINE_SMART_DROPOUTS and - FT_OUTLINE_EXCLUDE_STUBS, have been introduced. Together with - FT_OUTLINE_IGNORE_DROPOUTS (which was ignored previously) it is - now possible to control the dropout mode of the `raster' module - (for B&W rasterization), using the `flags' field in the - `FT_Outline' structure. - - - The TrueType bytecode interpreter now passes the dropout mode to - the B&W rasterizer. This greatly increases the output for small - ppem values of many fonts like `pala.ttf'. - - -====================================================================== - -CHANGES BETWEEN 2.3.6 and 2.3.5 - - I. IMPORTANT BUG FIXES - - - A bunch of potential security problems have been found. All - users should update. - - - Microsoft Unicode cmaps in TrueType fonts are now always - preferred over Apple cmaps. This is not a bug per se, but there - exist some buggy fonts created for MS which have broken Apple - cmaps. This affects only the automatic selection of FreeType; - it's always possible to manually select an Apple Unicode cmap if - desired. - - - Many bug fixes to the TrueType bytecode interpreter. - - - Improved Mac support. - - - Subsetted CID-keyed CFFs are now supported correctly. - - - CID-keyed CFFs with subfonts which are scaled in a non-standard - way are now handled correctly. - - - A call to FT_Open_Face with `face_index' < 0 crashed FreeType if - the font was a Windows (bitmap) FNT/FON. - - - II. IMPORTANT CHANGES - - - The new function `FT_Get_CID_Registry_Ordering_Supplement' gives - access to those fields in a CID-keyed font. The code has been - contributed by Derek Clegg. - - - George Williams contributed code to validate the new `MATH' - OpenType table (within the `otvalid' module). The `ftvalid' - demo program has been extended accordingly. - - - An API for cmap 14 support (for Unicode Variant Selectors, UVS) - has been contributed by George Williams. - - - A new face flag FT_FACE_FLAG_CID_KEYED has been added, together - with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is - CID-keyed. - - - III. MISCELLANEOUS - - - Build support for symbian has been contributed. - - - Better WGL4 glyph name support, contributed by Sergey Tolstov. - - - Debugging output of the various FT_TRACEX macros is now sent to - stderr. - - - The `ftview' demo program now provides artificial slanting too. - - - The `ftvalid' demo program has a new option `-f' to select the - font index. - - -====================================================================== - -CHANGES BETWEEN 2.3.5 and 2.3.4 - - I. IMPORTANT BUG FIXES - - - Some subglyphs in TrueType fonts were handled incorrectly due to - a missing graphics state reinitialization. - - - Large .Z files (as distributed with some X11 packages) weren't - handled correctly, making FreeType increase the heap stack in an - endless loop. - - - A large number of bugs have been fixed to avoid crashes and - endless loops with invalid fonts. - - - II. IMPORTANT CHANGES - - - The two new cache functions `FTC_ImageCache_LookupScaler' and - `FTC_SBit_Cache_LookupScaler' have been added to allow lookup of - glyphs using an `FTC_Scaler' object; this makes it possible to - use fractional pixel sizes in the cache. The demo programs have - been updated accordingly to use this feature. - - - A new API `FT_Get_CMap_Format' has been added to get the cmap - format of a TrueType font. This is useful in handling PDF - files. The code has been contributed by Derek Clegg. - - - The auto-hinter now produces better output by default for - non-Latin scripts like Indic. This was done by using the CJK - hinting module as the default instead of the Latin one. Thanks - to Rahul Bhalerao for this suggestion. - - - A new API `FT_Face_CheckTrueTypePatents' has been added to find - out whether a given TrueType font uses patented bytecode - instructions. The `ft2demos' bundle contains a new program - called `ftpatchk' which demonstrates its usage. - - - A new API `FT_Face_SetUnpatentedHinting' has been added to - enable or disable the unpatented hinter. - - - Support for Windows FON files in PE format has been contributed - by Dmitry Timoshkov. - - - III. MISCELLANEOUS - - - Vincent Richomme contributed Visual C++ project files for Pocket - PCs. - - -====================================================================== - -CHANGES BETWEEN 2.3.4 and 2.3.3 - - I. IMPORTANT BUG FIXES - - - A serious bug in the handling of bitmap fonts (and bitmap - strikes of outline fonts) has been introduced in 2.3.3. - - -====================================================================== - -CHANGES BETWEEN 2.3.3 and 2.3.2 - - I. IMPORTANT BUG FIXES - - - Remove a serious regression in the TrueType bytecode interpreter - that was introduced in version 2.3.2. Note that this does not - disable the improvements introduced to the interpreter in - version 2.3.2, only some ill cases that occurred with certain - fonts (though a few popular ones). - - - The auto-hinter now ignores single-point contours for computing - blue zones. This bug created `wavy' baselines when rendering - text with various fonts that use these contours to model - mark-attach points (these are points that are never rasterized - and are placed outside of the glyph's real outline). - - - The `rsb_delta' and `lsb_delta' glyph slot fields are now set to - zero for mono-spaced fonts. Otherwise code that uses them would - essentially ruin the fixed-advance property. - - - Fix CVE-2007-1351 which can cause an integer overflow while - parsing BDF fonts, leading to a potentially exploitable heap - overflow condition. - - - II. MISCELLANEOUS - - - Fixed compilation issues on some 64-bit platforms (see ChangeLog - for details). - - - A new demo program `ftdiff' has been added to compare TrueType - hinting, FreeType's auto hinting, and rendering without hinting - in three columns. - - -====================================================================== - -CHANGES BETWEEN 2.3.2 and 2.3.1 - - I. IMPORTANT BUG FIXES - - - FreeType returned incorrect kerning information from TrueType - fonts when the bytecode interpreter was enabled. This happened - due to a typo introduced in version 2.3.0. - - - Negative kerning values from PFM files are now reported - correctly (they were read as 16-bit unsigned values from the - file). - - - Fixed a small memory leak when `FT_Init_FreeType' failed for - some reason. - - - The Postscript hinter placed and sized very thin and ghost stems - incorrectly. - - - The TrueType bytecode interpreter has been fixed to get rid of - most of the rare differences seen in comparison to the Windows - font loader. - - - II. IMPORTANT CHANGES - - - The auto-hinter now better deals with serifs and corner cases - (e.g., glyph '9' in Arial at 9pt, 96dpi). It also improves - spacing adjustments and doesn't change widths for non-spacing - glyphs. - - - Many Mac-specific functions are deprecated (but still - available); modern replacements have been provided for them. - See the documentation in file `ftmac.h'. - - -====================================================================== - -CHANGES BETWEEN 2.3.1 and 2.3.0 - - I. IMPORTANT BUG FIXES - - - The TrueType interpreter sometimes returned incorrect horizontal - metrics due to a bug in the handling of the SHZ instruction. - - - A typo in a security check introduced after version 2.2.1 - prevented FreeType to render some glyphs in CFF fonts. - - -====================================================================== - -CHANGES BETWEEN 2.3.0 and 2.2.1 - - I. IMPORTANT BUG FIXES - - - The PCF font loader is now much more robust while loading - malformed font files. - - - Various memory leaks have been found and fixed. - - - The TrueType name loader now deals properly with some fonts that - encode their names in UTF-16 (the specification was vague, and - the code incorrectly assumed UCS-4). - - - Fixed the TrueType bytecode loader to deal properly with subtle - monochrome/gray issues when scaling the CVT. Some fonts - exhibited bad rendering artifacts otherwise. - - - `FT_GlyphSlot_Embolden' now supports vertical layouts correctly - (it mangled the vertical advance height). - - - Fixed byte endian issues of `ftmac.c' to support Mac OS X on - i386. - - - The PFR font loader no longer erroneously tags font files - without any outlines as FT_FACE_FLAG_SCALABLE. - - - II. NEW API FUNCTIONS - - - `FT_Library_SetLcdFilter' allows you to select a special filter - to be applied to the bitmaps generated by `FT_Render_Glyph' if - one of the FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V modes has - been selected. This filter is used to reduce color fringes; - several settings are available through the FT_LCD_FILTER_XXX - enumeration. - - Its declaration and documentation can be found in file - `include/freetype/ftlcdfil.h' (to be accessed with macro - FT_LCD_FILTER_H). - - *IMPORTANT*: This function returns an error - (FT_Err_Unimplemented_Feature) in default builds of the library - for patent reasons. See below. - - - `FT_Get_Gasp' allows you to query the flags of the TrueType - `gasp' table for a given character pixel size. This is useful - to duplicate the text rendering of MS Windows when the native - bytecode interpreter is enabled (which isn't the default for - other patent reasons). - - Its declaration and documentation can be found in file - `include/freetype/ftgasp.h' (to be accessed with macro - FT_GASP_H). - - - III. IMPORTANT CHANGES - - - The auto-hinter has been tuned a lot to improve its results with - serif fonts, resulting in much better font rendering of many web - pages. - - - The unpatented hinter is now part of the default build of the - library; we have added code to automatically support `tricky' - fonts that need it. - - This means that FreeType should `just work' with certain Asian - fonts, like MingLiU, which cannot properly be loaded without a - bytecode interpreter, but which fortunately do not use any of - the patented bytecode opcodes. We detect these fonts by name, - so please report any font file that doesn't seem to work with - FreeType, and we shall do what we can to support it in a next - release. - - Note that the API hasn't changed, so you can still force - unpatented hinting with a special parameter to `FT_Open_Face' as - well. This might be useful in same cases; for example, a PDF - reader might present a user option to activate it to deal with - certain `tricky' embedded fonts which cannot be clearly - identified. - - If you are a developer for embedded systems, you might want to - *disable* the feature to save code space by undefining - TT_CONFIG_OPTION_UNPATENTED_HINTING in file `ftoption.h'. - - - LCD-optimized rendering is now *disabled* in all default builds - of the library, mainly due to patent issues. For more - information see: - - https://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html - - A new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING - has been introduced in `ftoption.h'; manually define it in this - file if you want to re-enable the feature. - - The change only affects the implementation, not the FreeType - API. This means that clients don't need to be modified, because - the library still generates LCD decimated bitmaps, but with the - added constraint that R=G=B on each triplet. - - The displayed result should be equal to normal anti-aliased - rendering. - - Additionally, if FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not - defined, the new `FT_Library_SetLcdFilter' function returns the - FT_Err_Unimplemented_Feature error code. - - - Some computation bugs in the TrueType bytecode interpreter were - found, which allow us to get rid of very subtle and rare - differences we had experienced with the Windows renderer. - - - It is now possible to cross-compile the library easily. See the - file `docs/INSTALL.CROSS' for details. - - - The file `src/base/ftmac.c' now contains code for Mac OS X only; - its deprecated function `FT_GetFile_From_Mac_Font_Name' always - returns an error even if the QuickDraw framework is available. - The previous version has been moved to `builds/mac/ftmac.c'. - - Selecting configure option `--with-quickdraw-carbon' makes the - build process use the original `ftmac.c' file instead of the Mac - OS X-only version. - - - IV. MISCELLANEOUS - - - Various performance and memory footprint optimizations have been - performed on the TrueType and CFF font loaders, sometimes with - very drastic benefits (e.g., the TrueType loader is now about - 25% faster; FreeType should use less heap memory under nearly - all conditions). - - - The anti-aliased rasterizer has been optimized and is now 15% to - 25% percent faster than in previous versions, depending on - content. - - - The Type 1 loader has been improved; as an example, it now skips - top-level dictionaries properly. - - - Better support for Mac fonts on POSIX systems, plus compilation - fixes for Mac OS X on ppc64 where `ftmac.c' cannot be built. - - - Configuration without `--with-old-mac-fonts' does not include - `ftmac.c' (this was the behaviour in FreeType version 2.1.10). - - - The TrueTypeGX validator (gxvalid) checks the order of glyph IDs - in the kern table. - - -====================================================================== - -CHANGES BETWEEN 2.2.1 and 2.2 - - I. IMPORTANT BUG FIXES - - - Various integer overflows have been fixed. - - - PFB fonts with MacOS resource fork weren't handled correctly on - non-MacOS platforms. - - -====================================================================== - -CHANGES BETWEEN 2.2 and 2.1.10 - -(not released officially) - - I. IMPORTANT BUG FIXES - - - Vertical metrics for SFNT fonts were incorrect sometimes. - - - The FT_HAS_KERNING macro always returned 0. - - - CFF OpenType fonts didn't return correct vertical metrics for - glyphs with outlines. - - - If FreeType was compiled without hinters, all font formats based - on PS outlines weren't scaled correctly. - - - II. IMPORTANT CHANGES - - - Version 2.2 no longer exposes its internals, this is, the header - files located in the `include/freetype/internal' directory of - the source package are not copied anymore by the `make install' - command. Consequently, a number of rogue clients which directly - access FreeType's internal functions and structures won't - compile without modification. - - We provide patches for most of those rogue clients. See the - following page for more information: - - https://www.freetype.org/freetype2/patches/rogue-patches.html - - Note that, as a convenience to our Unix desktop users, version - 2.2 is *binary* compatible with FreeType 2.1.7, which means that - installing this release on an existing distribution shall not - break any working desktop. - - - FreeType's build mechanism has been redesigned. With GNU make - it is now sufficient in most cases to edit two files: - `modules.cfg', to select the library components, and the - configuration file `include/freetype/config/ftoption.h' (which - can be copied to the objects directory). Removing unused module - directories to prevent its compilation and editing - `include/freetype/config/ftmodule.h' is no longer necessary. - - - The LIGHT hinting algorithm produces more pleasant results. - Also, using the FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph - always forces auto-hinting, as a special exception. This allows - you to experiment with it even if you have enabled the TrueType - bytecode interpreter in your build. - - - The auto hinter now employs a new algorithm for CJK fonts, based - on Akito Hirai's patch. Note that this only works for fonts - with a Unicode charmap at the moment. - - - The following callback function types have changed slightly (by - adding the `const' keyword where appropriate): - - FT_Outline_MoveToFunc - FT_Outline_LineToFunc - FT_Outline_ConicToFunc - FT_Outline_CubicToFunc - FT_SpanFunc - FT_Raster_RenderFunc - - FT_Glyph_TransformFunc - FT_Renderer_RenderFunc - FT_Renderer_TransformFunc - - Note that this doesn't affect binary backward compatibility. - - - On MacOS, new APIs have been added as replacements for legacy - APIs: `FT_New_Face_From_FSRef' for `FT_New_Face_From_FSSpec', - and `FT_GetFile_From_Mac_ATS_Name' for - `FT_GetFile_From_Mac_Name'. Legacy APIs are still available, if - FreeType is built without disabling them. - - - A new API `FT_Select_Size' has been added to select a bitmap - strike by its index. Code using other functions to select - bitmap strikes should be updated to use this function. - - - A new API `FT_Get_SubGlyph_Info' has been added to retrieve - subglyph data. This can be used by rogue clients which used to - access the internal headers to get the corresponding data. - - - In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for - BDF/PCF fonts, and only for them. This causes inconsistency. - In this release, we undo the change. The intent of the change - in 2.1.10 is to allow size selection through real dimensions, - which can now be done through `FT_Request_Size'. - - - Some security issues were discovered and fixed in the CFF and - Type 1 loader, causing crashes of FreeType by malformed font - files. - - - III. MISCELLANEOUS - - - The documentation for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX - values now better reflects its usage and differences: One set is - used to specify the hinting algorithm, the other to specify the - pixel rendering mode. - - - `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been - changed to count supported scalable faces (sfnt, LWFN) only, and - to return the number of available faces via face->num_faces. - Unsupported bitmap faces (fbit, NFNT) are ignored. - - - builds/unix/configure has been improved for MacOS X. It now - automatically checks available functions in Carbon library, and - prepare to use newest functions by default. Options to specify - the dependencies of each Carbon APIs (FSSpec, FSRef, old/new - QuickDraw, ATS) are available too. By manual disabling of all - QuickDraw functionality, FreeType can be built without - `deprecated function' warnings on MacOS 10.4.x, but - FT_GetFile_Mac_Name in ftmac.c then is changed to a dummy - function, and returns an `unimplemented' error. For details see - builds/mac/README. - - - SFNT cmap handling has been improved, mainly to run much faster - with CJK fonts. - - - A new function `FT_Get_TrueType_Engine_Type (declared in - `FT_MODULE_H') is provided to determine the status of the - TrueType bytecode interpreter compiled into the library - (patented, unpatented, unimplemented). - - - Vertical metrics of glyphs are synthesized if the font does not - provide such information. You can tell whether the metrics are - synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of - the face. - - - The demo programs `ftview' and `ftstring' have been rewritten - for better readability. `ftview' has a new switch `-p' to test - FT_New_Memory_Face (instead of FT_New_Face). - - - FreeType now honours bit 1 in the `head' table of TrueType fonts - (meaning `left sidebearing point at x=0'). This helps with some - buggy fonts. - - - Rudimentary support for Adobe's new `SING Glyphlet' format. See - - https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf - - for more information. - - - The `ftdump' program from the `ft2demos' bundle now shows some - information about charmaps. It also supports a new switch `-v' - to increase verbosity. - - - Better AFM support. This includes track kerning support. - - -====================================================================== - -CHANGES BETWEEN 2.1.10 and 2.1.9 - - I. IMPORTANT BUG FIXES - - - The size comparison for BDF and PCF files could fail sometimes. - - - Some CFF files were still not loaded correctly. Patch from - Derek Noonburg. - - - The stroker still had some serious bugs. - - - Boris Letocha fixed a bug in the TrueType interpreter: The - NPUSHW instruction wasn't skipped correctly in IF clauses. Some - fonts like `Helvetica 75 Bold' failed. - - - Another serious bug in handling TrueType hints caused many - distortions. It has been introduced in version 2.1.8, and it is - highly recommended to upgrade. - - - FreeType didn't properly parse empty Type 1 glyphs. - - - An unbound dynamic buffer growth was fixed in the PFR loader. - - - Several bugs have been fixed in the cache sub-system. - - - FreeType behaved incorrectly when resizing two distinct but very - close character pixel sizes through `FT_Set_Char_Size' (Savannah - bug #12263). - - - The auto-hinter didn't work properly for fonts without a Unicode - charmap -- it even refused to load the glyphs. - - - II. IMPORTANT CHANGES - - - Many fixes have been applied to drastically reduce the amount of - heap memory used by FreeType, especially when using - memory-mapped font files (which is the default on Unix systems - which support them). - - - The auto-hinter has been replaced with a new module, called the - `auto-fitter'. It consumes less memory than its predecessor, - and it is prepared to support non-latin scripts better in next - releases. - - - George Williams contributed code to read kerning data from PFM - files. - - - FreeType now uses the TT_NAME_ID_PREFERRED_FAMILY and - TT_NAME_ID_PREFERRED_SUBFAMILY strings (if available) for - setting family and style in SFNT fonts (patch from Kornfeld - Eliyahu Peter). - - - A new API `FT_Sfnt_Table_Info' (in FT_TRUETYPE_TABLES_H) has - been added to retrieve name and size information of SFNT tables. - - - A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has - been added to validate OpenType tables (BASE, GDEF, GPOS, GSUB, - JSTF). After validation it is no longer necessary to check - for errors in those tables while accessing them. - - Note that this module might be moved to another library in the - future to avoid a tight dependency between FreeType and the - OpenType specification. - - - A new API in FT_BITMAP_H (`FT_Bitmap_New', `FT_Bitmap_Convert', - `FT_Bitmap_Copy', `FT_Bitmap_Embolden', `FT_Bitmap_Done') has - been added. Its use is to convert an FT_Bitmap structure in - 1bpp, 2bpp, 4bpp, or 8bpp format into another 8bpp FT_Bitmap, - probably using a different pitch, and to further manipulate it. - - - A new API `FT_Outline_Embolden' (in FT_OUTLINE_H) gives finer - control how outlines are emboldened. - - - `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H) now handles bitmaps - also (code contributed by Chia I Wu). Note that this function - is still experimental and may be replaced with a better API. - - - The method how BDF and PCF bitmap fonts are accessed has been - refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size - were synonyms in FreeType's BDF and PCF interface. This has - changed now. FT_Set_Pixel_Sizes should be used to select the - actual font dimensions (the `strike', which is the sum of the - `FONT_ASCENT' and `FONT_DESCENT' properties), while - FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE' - property). In both functions, the width parameter is ignored. - - - III. MISCELLANEOUS - - - The BDF driver no longer converts all returned bitmaps with a - depth of 2bpp or 4bpp to a depth of 8bpp. The documentation has - not mentioned this explicitly, but implementors might have - relied on this after looking into the source files. - - - A new option `--ftversion' has been added to freetype-config to - return the FreeType version. - - - The memory debugger has been updated to dump allocation - statistics on all allocation sources in the library. This is - useful to spot greedy allocations when loading and processing - fonts. - - - We removed a huge array of constant pointers to constant strings - in the `psnames' module. The problem was that compilations in - PIC mode (i.e., when generating a Unix shared object/dll) put - the array into the non-shared writable section of the library - since absolute pointers are not relocatable by nature. - - This reduces the memory consumption by approximately 16KByte per - process linked to FreeType. We now also store the array in a - compressed form (as a trie) which saves about 20KByte of code as - well. - - - Kirill Smelkov provided patches to make src/raster/ftraster.c - compile stand-alone again. - - -====================================================================== - -CHANGES BETWEEN 2.1.9 and 2.1.8 - - I. IMPORTANT BUG FIXES - - - The function `FT_Get_CharMap_Index' was only declared, without - any real code. For consistency, it has been renamed to - `FT_Get_Charmap_Index'. (This function is needed to implement - cmap caches.) - - - `FT_Outline_Get_BBox' sometimes returned incorrect values for - conic outlines (e.g., for TrueType fonts). - - - Handling of `bhed' table has been fixed. - - - The TrueType driver with enabled byte code interpreter sometimes - returned artifacts due to incorrect rounding. This bug has been - introduced after version 2.1.4. - - - The BDF driver dropped the last glyph in the font. - - - The BDF driver now uses the DEFAULT_CHAR property (if available) - to select a glyph shape for the undefined glyph. - - - The stroker failed for closed outlines and single points. - - - II. IMPORTANT CHANGES - - - George Williams contributed code to handle Apple's font - distortion technology found in GX fonts (`avar', `cvar', `fvar', - and `gvar' tables; the Multiple Masters API has been slightly - extended to cope with the new functionality). - - - The `FT_GlyphSlotRec' structure has been extended: The elements - `lsb_delta' and `rsb_delta' give the difference between hinted - and unhinted left and right side bearings if autohinting is - active. Using those values can improve the inter-letter spacing - considerably. See the documentation of `FT_GlyphSlotRec' and - the `ftstring' demo program how to use it. - - - Loading TrueType and Type 1 fonts has been made much faster. - - - The stroker is no longer experimental (but the cache subsystem - still is). - - - III. MISCELLANEOUS - - - A new documentation file `formats.txt' describes various font - formats supported (and not supported) by FreeType. - - -====================================================================== - -CHANGES BETWEEN 2.1.8 and 2.1.7 - - I. IMPORTANT BUG FIXES - - - The native TrueType hinter contained some bugs which prevented - some fonts to be rendered correctly, most notably Legendum.otf. - - - The PostScript hinter now produces improved results. - - - The linear advance width and height values were incorrectly - rounded, making them virtually unusable if not loaded with - FT_LOAD_LINEAR_DESIGN. - - - Indexing CID-keyed CFF fonts is now working: The glyph index is - correctly treated as a CID, similar to FreeType's CID driver - module. Note that CID CMap support is still missing. - - - The FT_FACE_FLAG_GLYPH_NAMES flag is now set correctly for all - font formats. - - - Some subsetted Type 1 fonts weren't parsed correctly. This bug - has been introduced in 2.1.7. In summary, the Type 1 parser has - become more robust. - - - Non-decimal numbers weren't parsed correctly in PS fonts. - - - The WinFNT driver now correctly reports FT_ENCODING_NONE for all - but one encoding. Use the new FT_WinFNT_ID_XXX values together - with `FT_Get_WinFNT_Header' to get the WinFNT charset ID. - - - The descender metrics (face->size->metrics.descender) for WinFNT - bitmap fonts had the wrong sign. - - - The (emulated) `seac' support for CFF fonts was broken. - - - The `flex' operator didn't work for CFF fonts. - - - PS glyphs which use the `hintmask' operator haven't been - rendered correctly in some cases. - - - Metrics for BDF and PCF bitmap font formats have been fixed. - - - Autohinting is now disabled for glyphs which are vertically - distorted or mirrored (using a transformation matrix). This - fixes a bug which produced zero-height glyphs. - - - The `freetype-config' script now handles --prefix and - --exec-prefix correctly; it also returns the proper --rpath (or - -R) value if FreeType has been built as a shared library. - - - II. IMPORTANT CHANGES - - - Both PCF and BDF drivers now handle the SETWIDTH_NAME and - ADD_STYLE_NAME properties. Values are appended to - face->style_name; example: `Bold SemiCondensed'. - - - The PCF driver now handles bitmap fonts compressed with the LZW - algorithm (extension .pcf.Z, compressed with `compress'). - - - A new API function `FT_Get_CMap_Language_ID' (declared in - `tttables.h') is available to get the language ID of a - TrueType/SFNT cmap. - - - The hexadecimal format of data after the `StartData' command in - CID-keyed Type 1 fonts is now supported. While this can't occur - in file-based fonts, it can happen in document-embedded - resources of PostScript documents. - - - Embedded bitmaps in SFNT-based CFF fonts are now supported. - - - A simple API is now available to control FreeType's tracing - mechanism if compiled with FT_DEBUG_LEVEL_TRACE. See the file - `ftdebug.h' for more details. - - - YAMATO Masatake contributed improved handling of MacOS resource - forks on non-MacOS platforms (for example, Linux can mount MacOS - file systems). - - - Support for MacOS has been improved; there is now a new function - `FT_New_Face_From_FSSpec' similar to `FT_New_Face' except that - it accepts an FSSpec instead of a path. - - - The cache sub-system has been rewritten. - - - There is now support for deinstallation of faces. - - - A new API function `FTC_Manager_RemoveFaceID' has been added - to delete all `idle' nodes that correspond to a given - FTC_FaceID. All `locked' nodes (i.e., those with a reference - count > 0), will be modified to prevent them from appearing in - further lookups (they will be cleaned normally when their - reference count reaches 0). - - - There is now support for point scaling (i.e., providing - character sizes in points + dpis, instead of pixels). - - - Three abstract cache classes are now available: - - FTC_GCache: Used to store one glyph item per cache node, - with the ability to group common attributes into - `families'. This replaces the old - FTC_GlyphCache class. - - FTC_ICache: Used to store one FT_Glyph per cache node. This - extends FTC_GCache. Family definition, family - comparison, and glyph loading are however left - to sub-classes. - - FTC_SCache: Used to store up to 16 small bitmaps per cache - node. This extends FTC_GCache. Family - definition, family comparison and glyph loading - are however left to sub-classes. - - - The file `src/cache/ftcbasic.c' implements: - - FTC_ImageCache: Extends FTC_ICache; implements family - definitions and glyph loading similar to the - old API. - - FTC_SBitCache: Extends FTC_SCache, implements family - definitions and glyph loading similar to the - old API - - Client applications should be able to extend FTC_GCache, - FTC_ICache, or FTC_SCache much more easily (i.e., less code to - write, and less callbacks). For example, one could envision - caches that are capable of storing transformed (obliqued), - stroked, emboldened, or colored glyph images. Use - `ftcbasic.c' as an example. - - - All public APIs are now in `include/freetype/ftcache.h', (to - be accessed as `FT_CACHE_H'). The contents of - `include/freetype/cache/' is only needed by applications that - wish to implement their own caches. - - - There were some major performance improvements through the use - of various programming tricks. Cache hits are up to 70% - faster than in the old code. - - - The FTC_CMapCache has been simplified. Charmaps can only be - accessed by index right now. There is also a new API named - `FT_Charmap_GetIndex' for this purpose. - - - The demo programs have been updated to the new code. The - previous versions will not work with the current one. - - - Using an invalid face index in FT_Open_Face and friends now - causes an error even if the font contains a single face only. - - - III. MISCELLANEOUS - - - Wolfgang Domröse contributed support files for building FreeType - on the Atari using the PureC compiler. Note that the Atari is a - 16bit platform. - - - Vitaliy Pasternak contributed project files for VS.NET 2003. - - -====================================================================== - -CHANGES BETWEEN 2.1.7 and 2.1.6 - - I. IMPORTANT BUG FIXES - - - Updated to newest libtool version, fixing build problems on - various platforms. - - - On Unix platforms, `make install' didn't copy the correct - `ftconfig.h' file. - - Note that version 2.1.7 contains the same library C source code as - version 2.1.6. - - -====================================================================== - -CHANGES BETWEEN 2.1.6 and 2.1.5 - - I. IMPORTANT BUG FIXES - - - The PFR font driver didn't load kerning tables correctly, and - the functions in FT_PFR_H didn't work at all. - - - Type 1 font files in binary format (PFB) with an end-of-file - indicator weren't accepted by the FreeType engine. - - - Fonts which contain /PaintType and /StrokeWidth no longer cause - a segfault. This bug has been introduced in version 2.1.5. - - - Fonts loaded with FT_LOAD_RENDER no longer cause strange - results. This bug has been introduced in version 2.1.5. - - - Some Windows (bitmap) FNT/FON files couldn't be handled - correctly. - - - II. IMPORTANT CHANGES - - - The internal module API has been heavily changed in favor of - massive simplifications within the font engine. This also means - that authors of third-party modules must adapt their code to the - new scheme. - - NOTE: THE NEW SCHEME IS NOT COMPLETED YET. PLEASE WAIT UNTIL A - FINAL ANNOUNCEMENT! - - - The PostScript parser has been enhanced to handle comments and - strings correctly. Additionally, more syntax forms are - recognized. - - - Added the optional unpatented hinting system for TrueType. It - allows typefaces which need hinting to produce correct glyph - forms (e.g., Chinese typefaces from Dynalab) to work acceptably - without infringing Apple patents. This system is compiled only - if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in - ftoption.h (activated by default). - - - III. MISCELLANEOUS - - - There is now a guard in the public header files to protect - against inclusion of freetype.h from FreeType 1. - - - Direct inclusion of freetype.h and other public header files no - longer works. You have to use the documented scheme - - #include - #include FT_FREETYPE_H - - to load freetype.h with a symbolic name. This protects against - renaming of public header files (which shouldn't happen but - actually has, avoiding two public header files with the same - name). - - -====================================================================== - -CHANGES BETWEEN 2.1.5 and 2.1.4 - - I. IMPORTANT BUG FIXES - - - Parsing the /CIDFontName field now removes the leading slash to - be in sync with other font drivers. - - - gzip support was buggy. Some fonts could not be read. - - - Fonts which have nested subglyphs more than one level deep no - longer cause a segfault. - - - Creation of synthetic cmaps for fonts in CFF format was broken - partially. - - - Numeric font dictionary entries for synthetic fonts are no - longer overwritten. - - - The font matrix wasn't applied to the advance width for Type1, - CID, and CFF fonts. This caused problems when loading certain - synthetic Type 1 fonts like `Helvetica Narrow'. - - - The test for the charset registry in BDF and PCF fonts is now - case-insensitive. - - - FT_Vector_Rotate sometimes returned strange values due to - rounding errors. - - - The PCF driver now returns the correct number of glyphs - (including an artificial `notdef' glyph at index 0). - - - FreeType now supports buggy CMaps which are contained in many - CJK fonts from Dynalab. - - - Opening an invalid font on a Mac caused a segfault due to - double-freeing memory. - - - BDF fonts with more than 32768 glyphs weren't supported - properly. - - - II. IMPORTANT CHANGES - - - Accessing bitmap font formats has been synchronized. To do that - the FT_Bitmap_Size structure has been extended to contain new - fields `size', `x_ppem', and `y_ppem'. - - - The FNT driver now returns multiple faces, not multiple strikes. - - - The `psnames' module has been updated to the Adobe Glyph List - version 2.0. - - - The `psnames' module now understands `uXXXX[X[X]]' glyph names. - - - The algorithm for guessing the font style has been improved. - - - For fonts in SFNT format, root->height is no longer increased if - the line gap is zero. There exist fonts (containing e.g. form - drawing characters) which intentionally have a zero line gap - value. - - - ft_glyph_bbox_xxx flags are now deprecated in favour of - FT_GLYPH_BBOX_XXX. - - - ft_module_xxx flags are now deprecated in favour of - FT_MODULE_XXX. - - - FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} are now - deprecated in favour of - FT_ENCODING_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} -- those encodings - are not specific to Microsoft. - - - III. MISCELLANEOUS - - - The autohinter has been further improved; for example, `m' - glyphs now retain its vertical symmetry. - - - Partial support of Mac fonts on non-Mac platforms. - - - `make refdoc' (after first `make') builds the HTML - documentation. You need Python for this. - - - The make build system should now work more reliably on DOS-like - platforms. - - - Support for EMX gcc and Watson C/C++ compilers on MS-DOS has - been added. - - - Better VMS build support. - - - Support for the pkg-config package by providing a `freetype.pc' - file. - - - New configure option --with-old-mac-fonts for Darwin. - - - Some source files have been renamed (mainly to fit into the 8.3 - naming scheme). - - -====================================================================== - -CHANGES BETWEEN 2.1.4 and 2.1.3 - - I. IMPORTANT BUG FIXES - - - Updated to newest libtool version, fixing build problems on - various platforms. - - - A fix in the Gzip stream reader: It couldn't read certain .gz - files properly due to a small typo. In certain cases, FreeType - could also loop endlessly when trying to load tiny gzipped - files. - - - The configure script now tries to use the system-wide zlib when - it finds one (instead of the copy found in src/gzip). And - `freetype-config' has been updated to return relevant flags in - this case when invoked with `--libs' (e.g. `-lzlib'). - - - Certain fonts couldn't be loaded by 2.1.3 because they lacked a - Unicode charmap (e.g. SYMBOL.TTF). FreeType erroneously - rejected them. - - - The CFF loader was modified to accept fonts which only contain a - subset of their reference charset. This prevented the correct - use of PDF-embedded fonts. - - - The logic to detect Unicode charmaps has been modified. This is - required to support fonts which include both 16-bit and 32-bit - charmaps (like very recent asian ones) using the new 10 and 12 - SFNT formats. - - - The TrueType loader now limits the depth of composite glyphs. - This is necessary to prevent broken fonts to break the engine by - blowing the stack with recursive glyph definitions. - - - The CMap cache is now capable of managing UCS-4 character codes - that are mapped through extended charmaps in recent - TrueType/OpenType fonts. - - - The cache sub-system now properly manages out-of-memory - conditions instead of blindly reporting them to the caller. - This means that it will try to empty the cache before restarting - its allocations to see if that can help. - - - The PFR driver didn't return the list of available embedded - bitmaps properly. - - - There was a nasty memory leak when using embedded bitmaps in - certain font formats. - - - II. IMPORTANT CHANGES - - - David Chester contributed some enhancements to the auto-hinter - that significantly increase the quality of its output. The - Postscript hinter was also improved in several ways. - - - The FT_RENDER_MODE_LIGHT render mode was implemented. - - - A new API function called `FT_Get_BDF_Property' has been added - to FT_BDF_H to retrieve BDF properties from BDF _and_ PCF font - files. THIS IS STILL EXPERIMENTAL, since it hasn't been - properly tested yet. - - - A Windows FNT specific API has been added, mostly to access font - headers. This is used by Wine. - - - TrueType tables without an `hmtx' table are now tolerated when - an incremental interface is used. This happens for certain - Type42 fonts passed from Ghostscript to FreeType. - - - The PFR font driver is now capable of returning the font family - and style names when they are available (instead of the sole - `FontID'). This is performed by parsing an *undocumented* - portion of the font file! - - - III. MISCELLANEOUS - - - The path stroker in FT_STROKER_H has entered beta stage. It now - works very well, but its interface might change a bit in the - future. More on this in later releases. - - - The documentation for FT_Size_Metrics didn't appear properly in - the API reference. - - - The file docs/VERSION.DLL has been updated to explain versioning - with FreeType (i.e., comparing release/libtool/so numbers, and - how to use them in autoconf scripts). - - - The installation documentation has been seriously revamped. - Everything is now in the `docs' directory. - - -====================================================================== - -CHANGES BETWEEN 2.1.3 and 2.1.2 - - I. IMPORTANT BUG FIXES - - - FT_Vector_Transform had been incorrectly modified in 2.1.2, - resulting in incorrect transformations being applied (for - example, rotations were processed in opposite angles). - - - The format 8 and 12 TrueType charmap enumeration routines have - been fixed (FT_Get_Next_Char returned invalid values). - - - The PFR font driver returned incorrect advance widths if the - outline and metrics resolution defined in the font file were - different. - - - FT_Glyph_To_Bitmap now returns successfully when called with an - FT_BitmapGlyph argument (it previously returned an error). - - - A bug in the Type 1 loader that prevented valid font bounding - boxes to be loaded from multiple master fonts. - - - The SFNT validation code has been rewritten. FreeType can now - load `broken' fonts that were usable on Windows, but not with - previous versions of the library. - - - The computation of bearings in the BDF driver has been fixed. - - - The Postscript hinter crashed when trying to hint certain glyphs - (more precisely, when trying to apply hints to an empty glyph - outline). - - - The TrueType glyph loader now supports composites in `Apple - format' (they differ slightly from Microsoft/OpenType ones in - the way transformation offsets are computed). - - - FreeType was very slow at opening certain asian CID/CFF fonts, - due to fixed increment in dynamic array re-allocations. This - has been changed to exponential behaviour to get acceptable - performance. - - - - II. IMPORTANT CHANGES - - - The PCF driver now supports gzip-compressed font files natively. - This means that you will be able to use all these bitmap fonts - that come with XFree86 with FreeType (and libXft/libXft2, by - extension). - - - The automatic and postscript hinters have both been updated. - This results in a relatively important increase of rendering - quality since many nasty defaults have been suppressed. Please - visit the web page: - - https://www.freetype.org/hinting/smooth-hinting.html - - for additional details on this topic. - - - The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32 - (instead of just being an FT_Int). This breaks source and - binary compatibility for 16bit systems only, while retaining - both of them for 32 and 64 bit ones. - - Some new flags have been added consequently: - - FT_LOAD_NO_AUTOHINT :: Disable the use of the auto-hinter - (but not native format hinters). - - FT_LOAD_TARGET_NORMAL :: Hint and render for normal - anti-aliased displays. - - FT_LOAD_TARGET_MONO :: Hint and render for 1-bit displays. - - FT_LOAD_TARGET_LCD :: Hint and render for horizontal RGB or - BGR subpixel displays (like LCD - screens). THIS IS STILL - EXPERIMENTAL! - - FT_LOAD_TARGET_LCD_V :: Same as FT_LOAD_TARGET_LCD, for - vertical subpixel displays (like - rotated LCD screens). THIS IS STILL - EXPERIMENTAL! - - FT_LOAD_MONOCHROME is still supported, but only affects - rendering, not the hinting. - - Note that the `ftview' demo program available in the `ft2demos' - package has been updated to support LCD-optimized display on - non-paletted displays (under Win32 and X11). - - - The PFR driver now supports embedded bitmaps (all formats - supported), and returns correct kerning metrics for all glyphs. - - - The TrueType charmap loader now supports certain `broken' fonts - that load under Windows without problems. - - - The cache API has been slightly modified (it's still a beta!): - - - The type FTC_ImageDesc has been removed; it is now replaced - by FTC_ImageTypeRec. Note that one of its fields is a - `load_flag' parameter for FT_Load_Glyph. - - - The field `num_grays' of FT_SBitRec has been changed to - `max_grays' in order to fit within a single byte. Its - maximum value is thus 255 (instead of 256 as previously). - - - III. MISCELLANEOUS - - - Added support for the DESTDIR variable during `make install'. - This simplifies packaging of FreeType. - - - Included modified copies of the ZLib sources in `src/gzip' in - order to support gzip-compressed PCF fonts. We do not use the - system-provided zlib for now, though this is a probable - enhancement for future releases. - - - The DocMaker tool used to generate the on-line API reference has - been completely rewritten. It is now located in - `src/tools/docmaker/docmaker.py'. Features: - - - better cross-referenced output - - more polished output - - uses Python regular expressions (though it didn't speed the - program) - - much more modular structure, which allows for different - `backends' in order to generate HTML, XML, or whatever - format. - - One can regenerate the API reference by calling: - - python src/tools/docmaker/docmaker.py \ - --prefix=ft2 \ - --title=FreeType-2.1.3 \ - --output= - include/freetype/*.h \ - include/freetype/config/*.h \ - include/freetype/cache/*.h - - - A new, experimental, support for incremental font loading (i.e., - loading of fonts where the glyphs are not in the font file - itself, but provided by an external component, like a Postscript - interpreter) has been added by Graham Asher. This is still work - in progress, however. - - - A new, EXPERIMENTAL, path stroker has been added. It doesn't - suffer from severe rounding errors and treat bezier arcs - directly. Still work in progress (i.e. not part of the official - API). See the file for some of the - details. - - - The massive re-formatting of sources and internal re-design is - still under-way. Many internal functions, constants, and types - have been renamed. - - -====================================================================== - -CHANGES BETWEEN 2.1.2 and 2.1.1 - - I. IMPORTANT BUG FIXES - - - Many font drivers didn't select a Unicode charmap by default - when a new face was opened (with the FT_CONFIG_OPTION_USE_CMAPS - options enabled), causing many applications to not be able to - display text correctly with the 2.1.x releases. - - - The PFR driver had a bug in its composite loading code that - produces incorrectly placed accents with many fonts. - - - The Type42 driver crashed sometimes due to a nasty bug. - - - The Type 1 custom encoding charmap didn't handle the case where - the first glyph index wasn't 0. - - - A serious typo in the TrueType composite loader produced - incorrectly placed glyphs in fonts like `Wingdings' and a few - others. - - - II. MISCELLANEOUS - - - The Win32 Visual C++ project file has been updated to include - the PFR driver as well. - - - `freetype.m4' is now installed by default by `make install' on - Unix systems. - - - The function FT_Get_PS_Font_Info now works with CID and Type42 - fonts as well. - - -====================================================================== - -CHANGES BETWEEN 2.1.1 and 2.1.0 - - I. IMPORTANT BUG FIXES - - - The `version_info' returned by `freetype-config' in 2.1.0 - returned an invalid value. It now returns 9:1:3 (2.0.9 returned - 9:0:3). - - - Version 2.1.0 couldn't be linked against applications on Win32 - and Amiga systems due to a new debug function that wasn't - properly propagated to the system-specific directory in - `builds'. - - - Various MacOS and Mac OS X specific fixes. - - - Fixed a bug in the TrueType charmap validation routines that - made version 2.1.0 too restrictive -- many popular fonts have - been rejected. - - - There was still a very small difference between the monochrome - glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the - bytecode interpreter enabled. This was caused by an invalid - flag setting in the TrueType glyph loader, making the rasterizer - change its drop-out control mode. Now the results should - _really_ be completely identical. - - - The TrueType name table loader has been improved to support many - popular though buggy Asian fonts. It now ignores empty name - entries, invalid pointer offsets and a few other incorrect - subtleties. Moreover, name strings are now loaded on demand, - which reduces the memory load of many faces (e.g. the ARIAL.TTF - font file contains a 10kByte name table with 70 names). - - - Fixed a bug in the Postscript hinter that prevented family blues - substitution to happen correctly. - - - II. NEW FEATURES - - - Three new font drivers in this release: - - * A BDF font driver, contributed by Franco Zappa Nardelli, - heavily modified by Werner Lemberg. It also supports - anti-aliased bitmaps (using a slightly extended BDF format). - - * A Type42 font driver, contributed by Roberto Alameda. It is - still experimental but seems to work relatively well. - - * A PFR font driver, contributed by David Turner himself. It - doesn't support PFR hinting -- note that BitStream has at - least two patents on this format! - - - III. MISCELLANEOUS - - - The cache sub-system has been optimized in important ways. - Cache hits are now significantly faster. For example, using the - CMap cache is about twice faster than calling FT_Get_Char_Index - on most platforms. Similarly, using an SBit cache is about five - times faster than loading the bitmaps from a bitmap file, and - 300 to 500 times faster than generating them from a scalable - format. - - Note that you should recompile your sources if you designed a - custom cache class for the FT2 Cache subsystem, since the - changes performed are source, but not binary, compatible. - - -====================================================================== - -CHANGES BETWEEN 2.1.0 and 2.0.9 - - I. IMPORTANT BUG FIXES - - - The TrueType bytecode interpreter has been fixed to produce - _exactly_ the same output as FreeType 1.x. Previous differences - were due to slightly distinct fixed-point computation routines - used to perform dot products and vector length measurements. - - It seems that native TrueType hinting is _extremely_ sensitive - to rounding errors. The required vector computation routines - have been optimized and placed within the `ttinterp.c' file. - - - Fixed the parsing of accelerator tables in the PCF font driver. - - - Fixed the Type1 glyph loader routine used to compute the font's - maximum advance width. - - - II. NEW FEATURES - - - The `configure' script used on Unix systems has been modified to - check that GNU Make is being used to build the library. - Otherwise, it will display a message proposing to use the - GNUMAKE environment variable to name it. - - The Unix-specific file README.UNX has been modified accordingly. - - - III. MISCELLANEOUS - - - The FreeType License in `docs/FTL.TXT' has been updated to - include a proposed preferred disclaimer. If you are using - FreeType in your products, you are encouraged (but not mandated) - to use the following text in your documentation: - - """ - Portions of this software are copyright © 1996-2002 The - FreeType Project (www.freetype.org). All rights reserved. - """ - - - The default size of the render pool has been reduced to 16kByte. - This shouldn't result in any noticeable performance penalty, - unless you are using the engine as-is to render very large and - complex glyphs. - - - The FreeType 2 redesign has begun. More information can be - found at this URL: - - https://www.freetype.org/freetype2/redesign.html - - The following internal changes have been performed within the - sources of this release: - - - Many internal types have been renamed to increase - consistency. The following should be true, except for - public types: - - * All structure types have a name ending in `Rec' (short - for `record'). - - * A pointer-to-structure type has the same name as the - structure, _without_ the `Rec' suffix. - - Example: - - typedef struct FooRec_ - { - ... - - } FooRec, *Foo; - - - Many internal macros have been renamed to increase - consistency. The following should be true: - - * All macros have a name beginning with `FT_'. This - required a few changes like - - ALLOC => FT_ALLOC - FREE => FT_FREE - REALLOC => FT_REALLOC - - * All macros are completely UPPERCASE. This required a - few changes like: - - READ_Short => FT_READ_SHORT - NEXT_Short => FT_NEXT_SHORT - GET_ULongLE => FT_GET_ULONG_LE - MEM_Set => FT_MEM_SET - MEM_Copy => FT_MEM_COPY - etc. - - * Whenever possible, all macro names follow the - FT__ pattern. For example - - ACCESS_Frame => FT_FRAME_ENTER - FORGET_Frame => FT_FRAME_EXIT - EXTRACT_Frame => FT_FRAME_EXTRACT - RELEASE_Frame => FT_FRAME_RELEASE - - FILE_Pos => FT_STREAM_POS - FILE_Seek => FT_STREAM_SEEK - FILE_Read => FT_STREAM_READ - FILE_ReadAt => FT_STREAM_READ_AT - READ_Fields => FT_STREAM_READ_FIELDS - - - Many internal functions have been renamed to follow the - FT__ pattern. For example: - - FT_Seek_Stream => FT_Stream_Seek - FT_Read_Stream_At => FT_Stream_ReadAt - FT_Done_Stream => FT_Stream_Close - FT_New_Stream => FT_Stream_Open - FT_New_Memory_Stream => FT_Stream_OpenMemory - FT_Extract_Frame => FT_Stream_ExtractFrame - - Note that method names do not contain `_'. - - - The FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been replaced - with FT_NEW_ARRAY and FT_RENEW_ARRAY which do not take a - type as the fourth argument. Instead, the array element - type size is computed automatically from the type of the - target pointer used. - - - A new object class, FT_CMap, has been introduced. These - internal objects are used to model character maps. This - eases the support of additional charmap types within the - engine. - - - A new configuration file named `ftstdlib.h' has been added - to `include/freetype/config'. It is used to define aliases - for _every_ routine of the ISO C library that the font - engine uses. Each aliases has a `ft_' prefix - (e.g. `ft_strlen' is an alias for `strlen'). - - This is used to ease the porting of FreeType 2 to exotic - runtime environments where the ISO C Library isn't available - (e.g. XFree86 extension modules). - - More details are available in the `ChangeLog' file. - - -====================================================================== - -CHANGES BETWEEN 2.0.9 and 2.0.8 - - I. IMPORTANT BUG FIXES - - - Certain fonts like `foxjump.ttf' contain broken name tables with - invalid entries and wild offsets. This caused FreeType to crash - when trying to load them. - - The SFNT `name' table loader has been fixed to be able to - support these strange fonts. - - Moreover, the code in charge of processing this table has been - changed to always favour Windows-formatted entries over other - ones. Hence, a font that works on Windows but not on the Mac - will load cleanly in FreeType and report accurate values for - Family & PostScript names. - - - The CID font driver has been fixed. It unfortunately returned a - Postscript Font name with a leading slash, as in - `/MunhwaGothic-Regular'. - - - FreeType 2 should now compile fine on AIX 4.3.3 as a shared - library. - - - A bug in the Postscript hinter has been found and fixed, - removing un-even stem widths at small pixel sizes (like 14-17). - - This improves the quality of a certain number of Postscript - fonts. - - - II. NEW FEATURES - - - A new function named `FT_Library_Version' has been added to - return the current library's major, minor, and patch version - numbers. This is important since the macros FREETYPE_MAJOR, - FREETYPE_MINOR, and FREETYPE_PATCH cannot be used when the - library is dynamically linked by a program. - - - Two new APIs have been added: `FT_Get_First_Char' and - `FT_Get_Next_Char'. - - Together, these can be used to iterate efficiently over the - currently selected charmap of a given face. Read the API - reference for more details. - - - III. MISCELLANEOUS - - - The FreeType sources are under heavy internal re-factoring. As - a consequence, we have created a branch named `STABLE' on the - CVS to hold all future releases/fixes in the 2.0.x family. - - The HEAD branch now contains the re-factored sources and - shouldn't be used for testing or packaging new releases. In - case you would like to access the 2.0.9 sources from our CVS - repository, use the tag `VER-2-0-9'. - - -====================================================================== - -CHANGES BETWEEN 2.0.8 and 2.0.7 - - I. IMPORTANT BUG FIXES - - - There was a small but nasty bug in `freetype-config.in' which - caused the `freetype-config' script to fail on Unix. - - This didn't prevent the installation of the library or even its - execution, but caused problems when trying to compile many Unix - packages that depend on it. - - - Some TrueType or OpenType fonts embedded in PDF documents do not - have a 'cmap', 'post' and 'name' as is required by the - specification. FreeType no longer refuses to load such fonts. - - - Various fixes to the PCF font driver. - - -====================================================================== - -CHANGES BETWEEN 2.0.7 and 2.0.6 - - I. IMPORTANT BUG FIXES - - - Fixed two bugs in the Type 1 font driver. The first one - resulted in a memory leak in subtle cases. The other one caused - FreeType to crash when trying to load `.gsf' files (Ghostscript - so-called Postscript fonts). - - (This made _many_ KDE applications crash on certain systems. - FreeType _is_ becoming a critical system component on Linux :-) - - - Fixed a memory leak in the CFF font driver. - - - Fixed a memory leak in the PCF font driver. - - - Fixed the Visual C++ project file - `builds/win32/visualc/freetype.dsp' since it didn't include the - Postscript hinter component, causing errors at build time. - - - Fixed a small rendering bug in the anti-aliased renderer that - only occurred when trying to draw thin (less than 1 pixel) - strokes. - - - Fixed `builds/unix/freetype2.a4' which is used to generate a - valid `freetype2.m4' for use with autoconf. - - - Fixed the OpenVMS Makefiles. - - - II. MISCELLANEOUS - - - Added `configure' and `install' scripts to the top-level - directory. A GNU-style installation is thus now easily possible - with - - ./configure - make - make install - - -====================================================================== - -CHANGES BETWEEN 2.0.6 and 2.0.5 - - I. IMPORTANT BUG FIXES - - - It wasn't possible to load embedded bitmaps when the auto-hinter - was used. This is now fixed. - - - The TrueType font driver didn't load some composites properly - (the sub-glyphs were slightly shifted, and this was only - noticeable when using monochrome rendering). - - - Various fixes to the auto-hinter. They merely improve the - output of sans-serif fonts. Note that there are still problems - with serifed fonts and composites (accented characters). - - - All scalable font drivers erroneously returned un-fitted glyph - advances when hinting was requested. This created problems for - a number of layout applications. This is a very old bug that - got undetected mainly because most test/demo program perform - rounding explicitly or implicitly (through the cache). - - - `FT_Glyph_To_Bitmap' did erroneously modify the source glyph in - certain cases. - - - `glnames.py' still contained a bug that made FreeType return - invalid names for certain glyphs. - - - The library crashed when loading certain Type 1 fonts like - `sadn.pfb' (`Stalingrad Normal'), which appear to contain - pathetic font info dictionaries. - - - The TrueType glyph loader is now much more paranoid and checks - everything when loading a given glyph image. This was necessary - to avoid problems (crashes and/or memory overwrites) with broken - fonts that came from a really buggy automatic font converter. - - - II. IMPORTANT UPDATES AND NEW FEATURES - - - Important updates to the Mac-specific parts of the library. - - - The caching sub-system has been completely re-designed, and its - API has evolved (the old one is still supported for backward - compatibility). - - The documentation for it is not yet completed, sorry. For now, - you are encouraged to continue using the old API. However, the - ftview demo program in the ft2demos package has already been - updated to use the new caching functions. - - - A new charmap cache is provided too. See `FTC_CMapCache'. This - is useful to perform character code -> glyph index translations - quickly, without the need for an opened FT_Face. - - - A NEW POSTSCRIPT HINTER module has been added to support native - hints in the following formats: PostScript Type 1, PostScript - CID, and CFF/CEF. - - Please test! Note that the auto-hinter produces better results - for a number of badly-hinted fonts (mostly auto-generated ones) - though. - - - A memory debugger is now part of the standard FreeType sources. - To enable it, define FT_DEBUG_MEMORY in - , and recompile the library. - - Additionally, define the _environment_ variable FT_DEBUG_MEMORY - and run any program using FreeType. When the library is exited, - a summary of memory footprints and possible leaks will be - displayed. - - This works transparently with _any_ program that uses FreeType. - However, you will need a lot of memory to use this (allocated - blocks are never released to the heap to detect double deletes - easily). - - - III. MISCELLANEOUS - - - We are aware of subtle differences between the output of - FreeType versions 1 and 2 when it comes to monochrome - TrueType-hinted glyphs. These are most probably due to small - differences in the monochrome rasterizers and will be worked out - in an upcoming release. - - - We have decided to fork the sources in a `stable' branch, and an - `unstable' one, since FreeType is becoming a critical component - of many Unix systems. - - The next bug-fix releases of the library will be named 2.0.7, - 2.0.8, etc., while the `2.1' branch will contain a version of - the sources where we will start major reworking of the library's - internals, in order to produce FreeType 2.2.0 (or even 3.0) in a - more distant future. - - We also hope that this scheme will allow much more frequent - releases than in the past. - - -====================================================================== - -CHANGES BETWEEN 2.0.5 and 2.0.4 - - NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER. THIS MODULE - WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1) - - - Fixed a bug that made certain glyphs, like `Cacute', `cacute' and - `lslash' unavailable from Unicode charmaps of Postscript fonts. - This prevented the correct display of Polish text, for example. - - - The kerning table of Type 1 fonts was loaded by FreeType, when its - AFM file was attached to its face, but the - FT_FACE_FLAG_HAS_KERNING bit flags was not set correctly, - preventing FT_Get_Kerning to return meaningful values. - - - Improved SFNT (TrueType & OpenType) charmap support. Slightly - better performance, as well as support for the new formats defined - by the OpenType 1.3 specification (8, 10, and 12) - - - Fixed a serious typo in `src/base/ftcalc.c' which caused invalid - computations in certain rare cases, producing ugly artefacts. - - - The size of the EM square is computed with a more accurate - algorithm for Postscript fonts. The old one caused slight errors - with embedded fonts found in PDF documents. - - - Fixed a bug in the cache manager that prevented normal LRU - behaviour within the cache manager, causing unnecessary reloads - (for FT_Face and FT_Size objects only). - - - Added a new function named `FT_Get_Name_Index' to retrieve the - glyph index of a given glyph name, when found in a face. - - - Added a new function named `FT_Get_Postscript_Name' to retrieve - the `unique' Postscript font name of a given face. - - - Added a new public header size named FT_SIZES_H (or - ) providing new FT_Size-management functions: - FT_New_Size, FT_Activate_Size, FT_Done_Size. - - - Fixed a reallocation bug that generated a dangling pointer (and - possibly memory leaks) with Postscript fonts (in - src/psaux/psobjs.c). - - - Many fixes for 16-bit correctness. - - - Removed many pedantic compiler warnings from the sources. - - - Added an Amiga build directory in `builds/amiga'. - - -====================================================================== - -CHANGES BETWEEN 2.0.4 and 2.0.3 - - - Fixed a rather annoying bug that was introduced in 2.0.3. Namely, - the font transformation set through FT_Set_Transform was applied - twice to auto-hinted glyphs, resulting in incorrectly rotated text - output. - - - Fixed _many_ compiler warnings. FT2 should now compile cleanly - with Visual C++'s most pedantic warning level (/W4). It already - compiled fine with GCC and a few other compilers. - - - Fixed a bug that prevented the linear advance width of composite - TrueType glyphs to be correctly returned. - - - Fixed the Visual C++ project files located in - `builds/win32/visualc' (previous versions used older names of the - library). - - - Many 32-bit constants have an `L' appended to their value, in - order to improve the 16-bitness of the code. Someone is actually - trying to use FT2 on an Atari ST machine! - - - Updated the `builds/detect.mk' file in order to automatically - build FT2 on AIX systems. AIX uses `/usr/sbin/init' instead of - `/sbin/init' and wasn't previously detected as a Unix platform by - the FreeType build system. - - - Updated the Unix-specific portions of the build system (new - libtool version, etc.). - - - The SFNT kerning loader now ensures that the table is sorted - (since some problem fonts do not meet this requirement). - - -======================================================================= - -CHANGES BETWEEN 2.0.3 and 2.0.2 - - I. CHANGES TO THE MODULES / FONT DRIVERS - - - THE AUTO-HINTER HAS BEEN SLIGHTLY IMPROVED, in order to fix - several annoying artefacts, mainly: - - - Blue zone alignment of horizontal stems wasn't performed - correctly, resulting in artefacts like the `d' being placed - one pixel below the `b' in some fonts like Time New Roman. - - - Overshoot thresholding wasn't performed correctly, creating - unpleasant artefacts at large character pixel sizes. - - - Composite glyph loading has been simplified. This gets rid - of various artefacts where the components of a composite - glyphs were not correctly spaced. - - These are the last changes to the current auto-hinting module. - A new hinting sub-system is currently in the work in order to - support native hints in Type 1 / CFF / OpenType fonts, as well - as globally improve rendering. - - - The PCF driver has been fixed. It reported invalid glyph - dimensions for the fonts available on Solaris. - - - The Type 1, CID and CFF drivers have been modified to fix the - computation of the EM size. - - - The Type 1 driver has been fixed to avoid a dangerous bug that - crashed the library with non-conforming fonts (i.e. ones that do - not place the .notdef glyph at position 0). - - - The TrueType driver had a rather subtle bug (dangling pointer - when loading composite glyphs) that could crash the library in - rare occasions! - - - II. HIGH-LEVEL API CHANGES - - - The error code enumeration values have been changed. An error - value is decomposed in a generic error code, and a module - number. see for details. - - - A new public header file has been introduced, named - FT_TRIGONOMETRY_H (include/freetype/fttrigon.h), providing - trigonometric functions to compute sines, cosines, arctangents, - etc. with 16.16 fixed precision. The implementation is based on - the CORDIC algorithm and is very fast while being sufficiently - accurate. - - - III. INTERNALS - - - Added BeOS-specific files in the old build sub-system. Note - that no changes were required to compile the library with Jam. - - - The configuration is now capable of automatically detecting - 64-bit integers on a set of predefined compilers (GCC, Visual - C++, Borland C++) and will use them by default. This provides a - small performance boost. - - - A small memory leak that happened when opening 0-sized files - (duh!) have been fixed. - - - Fixed bezier stack depth bug in the routines provided by the - FT_BBOX_H header file. Also fixed similar bugs in the - rasterizers. - - - The outline bounding box code has been rewritten to use direct - computations, instead of bezier sub-division, to compute the - exact bounding box of glyphs. This is slightly slower but more - accurate. - - - The build system has been improved and fixed, mainly to support - `make' on Windows 2000 correctly, avoid problems with `make - distclean' on non Unix systems, etc. - - - Hexadecimal constants have been suffixed with `U' to avoid - problems with certain compilers on 64-bit platforms. - - - A new directory named `src/tools' has been created. It contains - Python scripts and simple unit test programs used to develop the - library. - - - The DocMaker tool has been moved from `docs' to `src/tools' and - has been updated with the following: - - - Now accepts the `--title=XXXX' or `-t XXXX' option from the - command line to set the project's name in the generated API - reference. - - - Now accepts the `--output=DIR' or `-o DIR' option from the - command line to set the output directory for all generated - HTML files. - - - Now accepts the `--prefix=XXXX' or `-p XXX' option from the - command line to set the file prefix to use for all - generated HTML files. - - - Now generates the current time/data on each generated page - in order to distinguish between versions. - - DocMaker can be used with other projects now, not only FT2 - (e.g. MLib, FTLayout, etc.). - - -====================================================================== - -CHANGES BETWEEN 2.0.2 and 2.0.1 - - I. CHANGES TO THE MODULES / FONT DRIVERS - - - THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to - avoid legal problems with the Apple patents. It seems that we - mistakenly turned this option on in previous releases of the - build. - - Note that if you want to use the bytecode interpreter in order - to get high-quality TrueType rendering, you will need to toggle - by hand the definition of the - TT_CONFIG_OPTION_BYTECODE_INTERPRETER macro in the file - `include/freetype/config/ftoption.h'. - - - The CFF driver has been improved by Tom Kacvinsky and Sander van - der Wal: - - * Support for `seac' emulation. - * Support for `dotsection'. - * Support for retrieving glyph names through - `FT_Get_Glyph_Name'. - - The first two items are necessary to correctly a large number of - Type 1 fonts converted to the CFF formats by Adobe Acrobat. - - - The Type 1 driver was also improved by Tom & others: - - * Better EM size computation. - * Better support for synthetic (transformed) fonts. - * The Type 1 driver returns the charstrings corresponding to - each glyph in the `glyph->control_data' field after a call to - `FT_Load_Glyph' (thanks Ha Shao). - - - Various other bugfixes, including the following: - - * Fixed a nasty memory leak in the Type 1 driver. - * The autohinter and the pcf driver used static writable data - when they shouldn't. - * Many casts were added to make the code more 64-bits safe. It - also now compiles on Windows XP 64-bits without warnings. - * Some incorrect writable statics were removed in the `autohint' - and `pcf' drivers. FreeType 2 now compiles on Epoc again. - - - II. CHANGES TO THE HIGH-LEVEL API - - - The library header files inclusion scheme has been changed. The - old scheme looked like: - - #include - #include - #include - #include - - Now you should use: - - #include - #include FT_FREETYPE_H - #include FT_GLYPH_H - #include FT_CACHE_H - #include FT_CACHE_IMAGE_H - - NOTE THAT THE OLD INCLUSION SCHEME WILL STILL WORK WITH THIS - RELEASE. HOWEVER, WE DO NOT GUARANTEE THAT THIS WILL STILL BE - TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1). - - The file is used to define the header filename - macros. The complete and commented list of macros is available - in the API reference under the section name `Header File Macros' - in Chapter I. - - For more information, see section I of the following document: - - https://www.freetype.org/freetype2/docs/tutorial/step1.html - - - Many, many comments have been added to the public source file in - order to automatically generate the API Reference through the - `docmaker.py' Python script. - - The latter has been updated to support the grouping of sections - in chapters and better index sort. See: - - https://www.freetype.org/freetype2/docs/reference/ft2-toc.html - - - III. CHANGES TO THE BUILD PROCESS - - - If you are not building FreeType 2 with its own build system - (but with your own Makefiles or project files), you will need to - be aware that the build process has changed a little bit. - - You don't need to put the `src' directory in the include path - when compiling any FT2 component. Instead, simply put the - component's directory in the current include path. - - So, if you were doing something like: - - cc -c -Iinclude -Isrc src/base/ftbase.c - - change the line to: - - cc -c -Iinclude -Isrc/base src/base/ftbase.c - - If you were doing something like: - - cd src/base - cc -c -I../../include -I.. ftbase.c - - change it to: - - cd src/base - cc -c -I../../include ftbase.c - - -====================================================================== - -CHANGES BETWEEN 2.0.1 and 2.0 - - 2.0.1 introduces a few changes: - - - Fixed many bugs related to the support of CFF / OpenType fonts. - These formats are now much better supported though there is - still work planned to deal with charset tables and PDF-embedded - CFF files that use the old `seac' command. - - - The library could not be compiled in debug mode with a very - small number of C compilers whose pre-processors didn't - implement the `##' directive correctly (i.e. per se the ANSI C - specification!) An elegant fix was found. - - - Added support for the free Borland command-line C++ Builder - compiler. Use `make setup bcc32'. Also fixed a few source - lines that generated new warnings with BCC32. - - - Fixed a bug in FT_Outline_Get_BBox when computing the extrema of - a conic Bezier arc. - - - Updated the INSTALL file to add IDE compilation. - - - Other minor bug fixes, from invalid Type 1 style flags to - correct support of synthetic (obliqued) fonts in the - auto-hinter, better support for embedded bitmaps in a SFNT font. - - - Fixed some problems with `freetype-config'. - - Finally, the `standard' scheme for including FreeType headers is now - gradually changing, but this will be explained in a later release - (probably 2.0.2). - - And very special thanks to Tom Kacvinsky and YAMANO-UCHI Hidetoshi - for their contributions! - - -====================================================================== - -CHANGES BETWEEN beta8 and 2.0 - - - Changed the default installation path for public headers from - `include/freetype' to `include/freetype2'. - - Also added a new `freetype-config' that is automatically generated - and installed on Unix and Cygwin systems. The script itself is - used to retrieve the current install path, C compilation flags as - well as linker flags. - - - Fixed several small bugs: - - * Incorrect max advance width for fixed-pitch Type 1 fonts. - * Incorrect glyph names for certain TrueType fonts. - * The glyph advance was not copied when FT_Glyph_To_Bitmap was - called. - * The linearHoriAdvance and linearVertAdvance fields were not - correctly returned for glyphs processed by the auto-hinter. - * `type1z' renamed back to `type1'; the old `type1' module has - been removed. - - - Revamped the build system to make it a lot more generic. This - will allow us to re-use nearly un-modified in lots of other - projects (including FreeType Layout). - - - Changed `cid' to use `psaux' too. - - - Added the cache sub-system. See as well as - the sources in `src/cache'. Note that it compiles but is still - untested for now. - - - Updated `docs/docmaker.py', a draft API reference is available at - https://web.archive.org/web/20001215173400/http://www.freetype.org:80/ft2api.html. - - - Changed `type1' to use `psaux'. - - - Created a new module named `psaux' to hold the Type 1 & Type 2 - parsing routines. It should be used by `type1', `cid', and `cff' - in the future. - - - Fixed an important bug in `FT_Glyph_Get_CBox'. - - - Fixed some compiler warnings that happened since the TrueType - bytecode decoder was deactivated by default. - - - Fixed two memory leaks: - - * The memory manager (16 bytes) isn't released in - FT_Done_FreeType! - * Using custom input streams, the copy of the original stream was - never released. - - - Fixed the auto-hinter by performing automatic computation of the - `filling direction' of each glyph. This is done through a simple - and fast approximation, and seems to work (problems spotted by - Werner though). The Arphic fonts are a lot nicer though there are - still a lot of things to do to handle Asian fonts correctly. - - -====================================================================== - -BETA-8 (RELEASE CANDIDATE) CHANGES - - - Deactivated the TrueType bytecode interpreter by default. - - - Deactivated the `src/type1' font driver. Now `src/type1z' is used - by default. - - - Updates to the build system. We now compile the library correctly - under Unix system through `configure' which is automatically - called on the first `make' invocation. - - - Added the auto-hinting module! Fixing some bugs here and there. - - - Found some bugs in the composite loader (seac) of the Type1-based - font drivers. - - - Renamed the directory `freetype2/config' to `freetype2/builds' and - updated all relevant files. - - - Found a memory leak in the `type1' driver. - - - Incorporated Tom's patches to support flex operators correctly in - OpenType/CFF fonts. Now all I need is to support pure CFF and CEF - fonts to be done with this driver :-) - - - Added the Windows FNT/FON driver in `src/winfonts'. For now, it - always `simulates' a Unicode charmap, so it shouldn't be - considered completed right now. - - It is there to be more a proof of concept than anything else - anyway. The driver is a single C source file, that compiles to 3 - Kb of code. - - I'm still working on the PCF/BDF drivers, but I'm too lazy to - finish them now. - - - CHANGES TO THE HIGH-LEVEL API - - * FT_Get_Kerning has a new parameter that allows you to select the - coordinates of the kerning vector (font units, scaled, scaled + - grid-fitted). - * The outline functions are now in and not - part of anymore. - * now contains declarations for - FT_New_Library, FT_Done_Library, FT_Add_Default_Modules. - * The so-called convenience functions have moved from `ftoutln.c' - to `ftglyph.c', and are thus available with this optional - component of the library. They are declared in - now. - * Anti-aliased rendering is now the default for FT_Render_Glyph - (i.e. corresponds to render_mode == 0 == ft_render_mode_normal). - To generate a monochrome bitmap, use ft_render_mode_mono, or the - FT_LOAD_MONOCHROME flag in FT_Load_Glyph/FT_Load_Char. - FT_LOAD_ANTI_ALIAS is still defined, but values to 0. - * now include , - solving a few headaches :-) - * The type FT_GlyphSlotRec has now a `library' field. - - - CHANGES TO THE `ftglyph.h' API - - This API has been severely modified in order to make it simpler, - clearer, and more efficient. It certainly now looks like a real - `glyph factory' object, and allows client applications to manage - (i.e. transform, bbox and render) glyph images without ever - knowing their original format. - - - Added support for CID-keyed fonts to the CFF driver. Maybe - support for pure CFF + CEF fonts should come in? - - - Cleaned up source code in order to avoid two functions with the - same name. Also changed the names of the files in `type1z' from - `t1XXXX' to `z1XXXX' in order to avoid any conflicts. - - `make multi' now works well :-) - - Also removed the use of `cidafm' for now, even if the source files - are still there. This functionality will certainly go into a - specific module. - - - ADDED SUPPORT FOR THE AUTO-HINTER - - It works :-) I have a demo program which simply is a copy of - `ftview' that does a `FT_Add_Module(library, - &autohinter_module_class)' after library initialization, and Type - 1 & OpenType/CFF fonts are now hinted. - - CID fonts are not hinted, as they include no charmap and the - auto-hinter doesn't include `generic' global metrics computations - yet. - - Now, I need to release this thing to the FreeType 2 source. - - - CHANGES TO THE RENDERER MODULES - - The monochrome and smooth renderers are now in two distinct - directories, namely `src/raster1' and `src/smooth'. Note that the - old `src/renderer' is now gone. - - I ditched the 5-gray-levels renderers. Basically, it involved a - simple #define toggle in 'src/raster1/ftraster.c'. - - FT_Render_Glyph, FT_Outline_Render & FT_Outline_Get_Bitmap now - select the best renderer available, depending on render mode. If - the current renderer for a given glyph image format isn't capable - of supporting the render mode, another one will be found in the - library's list. This means that client applications do not need - to switch or set the renderers themselves (as in the latest - change), they'll get what they want automatically. At last. - - Changed the demo programs accordingly. - - - MAJOR INTERNAL REDESIGN: - - A lot of internal modifications have been performed lately on the - source in order to provide the following enhancements: - - * More generic module support: - - The FT_Module type is now defined to represent a handle to a - given module. The file contains the - FT_Module_Class definition, as well as the module-loading public - API. - - The FT_Driver type is still defined, and still represents a - pointer to a font driver. Note that FT_Add_Driver is replaced - by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc. - - * Support for generic glyph image types: - - The FT_Renderer type is a pointer to a module used to perform - various operations on glyph image. - - Each renderer is capable of handling images in a single format - (e.g. ft_glyph_format_outline). Its functions are used to: - - - transform an glyph image - - render a glyph image into a bitmap - - return the control box (dimensions) of a given glyph image - - The scan converters `ftraster.c' and `ftgrays.c' have been moved - to the new directory `src/renderer', and are used to provide two - default renderer modules. - - One corresponds to the `standard' scan-converter, the other to - the `smooth' one. - - he current renderer can be set through the new function - FT_Set_Renderer. - - The old raster-related function FT_Set_Raster, FT_Get_Raster and - FT_Set_Raster_Mode have now disappeared, in favor of the new: - - FT_Get_Renderer - FT_Set_Renderer - - See the file for more details. - - These changes were necessary to properly support different - scalable formats in the future, like bi-color glyphs, etc. - - * Glyph loader object: - - A new internal object, called a 'glyph loader' has been - introduced in the base layer. It is used by all scalable format - font drivers to load glyphs and composites. - - This object has been created to reduce the code size of each - driver, as each one of them basically re-implemented its - functionality. - - See and the FT_GlyphLoader type for - more information. - - * FT_GlyphSlot has new fields: - - In order to support extended features (see below), the - FT_GlyphSlot structure has a few new fields: - - linearHoriAdvance: - - This field gives the linearly scaled (i.e. scaled but - unhinted) advance width for the glyph, expressed as a 16.16 - fixed pixel value. This is useful to perform WYSIWYG text. - - linearVertAdvance: - This field gives the linearly scaled advance height for the - glyph (relevant in vertical glyph layouts only). This is - useful to perform WYSIWYG text. - - Note that the two above field replace the removed `metrics2' - field in the glyph slot. - - advance: - This field is a vector that gives the transformed advance for - the glyph. By default, it corresponds to the advance width, - unless FT_LOAD_VERTICAL_LAYOUT was specified when calling - FT_Load_Glyph or FT_Load_Char. - - bitmap_left: - This field gives the distance in integer pixels from the - current pen position to the left-most pixel of a glyph image - IF IT IS A BITMAP. It is only valid when the `format' field - is set to `ft_glyph_format_bitmap', for example, after calling - the new function FT_Render_Glyph. - - bitmap_top: - This field gives the distance in integer pixels from the - current pen position (located on the baseline) to the top-most - pixel of the glyph image IF IT IS A BITMAP. Positive values - correspond to upwards Y. - - loader: - This is a new private field for the glyph slot. Client - applications should not touch it. - - - * Support for transforms and direct rendering in FT_Load_Glyph: - - Most of the functionality found in has been - moved to the core library. Hence, the following: - - - A transform can be specified for a face through - FT_Set_Transform. this transform is applied by FT_Load_Glyph - to scalable glyph images (i.e. NOT TO BITMAPS) before the - function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM - was set in the load flags. - - - Once a glyph image has been loaded, it can be directly - converted to a bitmap by using the new FT_Render_Glyph - function. Note that this function takes the glyph image from - the glyph slot, and converts it to a bitmap whose properties - are returned in `face.glyph.bitmap', `face.glyph.bitmap_left' - and `face.glyph.bitmap_top'. The original native image might - be lost after the conversion. - - - When using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph - and FT_Load_Char functions will call FT_Render_Glyph - automatically when needed. - - - Reformatted all modules source code in order to get rid of the - basic data types redefinitions (i.e. `TT_Int' instead of `FT_Int', - `T1_Fixed' instead of `FT_Fixed'). Hence the format-specific - prefixes like `TT_', `T1_', `T2_' and `CID_' are only used for - relevant structures. - - -====================================================================== - -OLD CHANGES FOR BETA 7 - - - bug-fixed the OpenType/CFF parser. It now loads and displays my - two fonts nicely, but I'm pretty certain that more testing is - needed :-) - - - fixed the crummy Type 1 hinter, it now handles accented characters - correctly (well, the accent is not always well placed, but that's - another problem..) - - - added the CID-keyed Type 1 driver in `src/cid'. Works pretty well - for only 13 Kb of code ;-) Doesn't read AFM files though, nor the - really useful CMAP files.. - - - fixed two bugs in the smooth renderer (src/base/ftgrays.c). - Thanks to Boris Letocha for spotting them and providing a fix. - - - fixed potential `divide by zero' bugs in ftcalc.c. - - - added source code for the OpenType/CFF driver (still incomplete - though..) - - - modified the SFNT driver slightly to perform more robust header - checks in TT_Load_SFNT_Header. This prevents certain font files - (e.g. some Type 1 Multiple Masters) from being incorrectly - `recognized' as TrueType font files.. - - - moved a lot of stuff from the TrueType driver to the SFNT module, - this allows greater code re-use between font drivers - (e.g. TrueType, OpenType, Compact-TrueType, etc..) - - - added a tiny segment cache to the SFNT Charmap 4 decoder, in order - to minimally speed it up.. - - - added support for Multiple Master fonts in `type1z'. There is - also a new file named which defines functions to - manage them from client applications. - - The new file `src/base/ftmm.c' is also optional to the engine.. - - - various formatting changes (e.g. EXPORT_DEF -> FT_EXPORT_DEF) + - small bug fixes in FT_Load_Glyph, the `type1' driver, etc.. - - - a minor fix to the Type 1 driver to let them apply the font matrix - correctly (used for many oblique fonts..) - - - some fixes for 64-bit systems (mainly changing some FT_TRACE calls - to use %p instead of %lx). Thanks to Karl Robillard. - - - fixed some bugs in the sbit loader (src/base/sfnt/ttsbit.c) + - added a new flag, FT_LOAD_CROP_BITMAP to query that bitmaps be - cropped when loaded from a file (maybe I should move the bitmap - cropper to the base layer ??). - - - changed the default number of gray levels of the smooth renderer - to 256 (instead of the previous 128). Of course, the human eye - can't see any difference ;-) - - - removed TT_MAX_SUBGLYPHS, there is no static limit on the number - of subglyphs in a TrueType font now.. - - -====================================================================== - -OLD CHANGES 16 May 2000 - - - tagged `BETA-6' in the CVS tree. This one is a serious release - candidate even though it doesn't incorporate the auto-hinter yet.. - - - various obsolete files were removed, and copyright header updated - - - finally updated the standard raster to fix the monochrome - rendering bug + re-enable support for 5-gray levels anti-aliasing - (suck, suck..) - - - created new header files, and modified sources accordingly: - - - - simple FreeType types, without the API - - - definition of memory-management macros - - - added the `DSIG' (OpenType Digital Signature) tag to - - - - light update/cleaning of the build system + changes to the sources - in order to get rid of _all_ compiler warnings with three - compilers, i.e: - - gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and - LCC - - IMPORTANT NOTE FOR WIN32-LCC USERS: - | - | It seems the C pre-processor that comes with LCC is broken, it - | doesn't recognize the ANSI standard directives # and ## - | correctly when one of the argument is a macro. Also, - | something like: - | - | #define F(x) print##x - | - | F(("hello")) - | - | will get incorrectly translated to: - | - | print "hello") - | - | by its pre-processor. For this reason, you simply cannot build - | FreeType 2 in debug mode with this compiler.. - - - yet another massive grunt work. I've changed the definition of - the EXPORT_DEF, EXPORT_FUNC, BASE_DEF & BASE_FUNC macros. These - now take an argument, which is the function's return value type. - - This is necessary to compile FreeType as a DLL on Windows and - OS/2. Depending on the compiler used, a compiler-specific keyword - like __export or __system must be placed before (VisualC++) or - after (BorlandC++) the type.. - - Of course, this needed a lot of changes throughout the source code - to make it compile again... All cleaned up now, apparently.. - - Note also that there is a new EXPORT_VAR macro defined to allow - the _declaration_ of an exportable public (constant) - variable. This is the case of the raster interfaces (see - ftraster.h and ftgrays.h), as well as each module's interface (see - sfdriver.h, psdriver.h, etc..) - - - new feature: it is now possible to pass extra parameters to font - drivers when creating a new face object. For now, - this capability is unused. It could however prove to - be useful in a near future.. - - the FT_Open_Args structure was changes, as well as the internal - driver interface (the specific `init_face' module function has - now a different signature). - - - updated the tutorial (not finished though). - - - updated the top-level BUILD document - - - fixed a potential memory leak that could occur when loading - embedded bitmaps. - - - added the declaration of FT_New_Memory_Face in - , as it was missing from the public header - (the implementation was already in `ftobjs.c'). - - - the file has been seriously updated in order - to allow the automatic generation of error message tables. See - the comments within it for more information. - - - major directory hierarchy re-organisation. This was done for two - things: - - * first, to ease the `manual' compilation of the library by - requiring at lot less include paths :-) - - * second, to allow external programs to effectively access - internal data fields. For example, this can be extremely - useful if someone wants to write a font producer or a font - manager on top of FreeType. - - Basically, you should now use the 'freetype/' prefix for header - inclusion, as in: - - #include - #include - - Some new include sub-directories are available: - - a. the `freetype/config' directory, contains two files used to - configure the build of the library. Client applications - should not need to look at these normally, but they can if - they want. - - #include - #include - - b. the `freetype/internal' directory, contains header files that - describes library internals. These are the header files that - were previously found in the `src/base' and `src/shared' - directories. - - - As usual, the build system and the demos have been updated to - reflect the change.. - - Here's a layout of the new directory hierarchy: - - TOP_DIR - include/ - freetype/ - freetype.h - ... - config/ - ftoption.h - ftconfig.h - ftmodule.h - - internal/ - ftobjs.h - ftstream.h - ftcalc.h - ... - - src/ - base/ - ... - - sfnt/ - psnames/ - truetype/ - type1/ - type1z/ - - - Compiling a module is now much easier, for example, the following - should work when in the TOP_DIR directory on an ANSI build: - - gcc -c -I./include -I./src/base src/base/ftbase.c - gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c - etc.. - - (of course, using -Iconfig/ if you provide system-specific - configuration files). - - - updated the structure of FT_Outline_Funcs in order to allow direct - coordinate scaling within the outline decomposition routine (this - is important for virtual `on' points with TrueType outlines) + - updates to the rasters to support this.. - - - updated the OS/2 table loading code in `src/sfnt/ttload.c' in - order to support version 2 of the table (see OpenType 1.2 spec) - - - created `include/tttables.h' and `include/t1tables.h' to allow - client applications to access some of the SFNT and T1 tables of a - face with a procedural interface (see `FT_Get_Sfnt_Table') + - updates to internal source files to reflect the change.. - - - some cleanups in the source code to get rid of warnings when - compiling with the `-Wall -W -ansi -pedantic' options in gcc. - - - debugged and moved the smooth renderer to `src/base/ftgrays.c' and - its header to `include/ftgrays.h' - - - updated TT_MAX_SUBGLYPHS to 96 as some CJK fonts have composites - with up to 80 sub-glyphs !! Thanks to Werner - - -====================================================================== - -OLD CHANGES - 14-apr-2000 - - - fixed a bug in the TrueType glyph loader that prevented the - correct loading of some CJK glyphs in mingli.ttf - - - improved the standard Type 1 hinter in `src/type1' - - - fixed two bugs in the experimental Type 1 driver in `src/type1z' - to handle the new XFree86 4.0 fonts (and a few other ones..) - - - the smooth renderer is now complete and supports sub-banding to - render large glyphs at high speed. However, it is still located - in `demos/src/ftgrays.c' and should move to the library itself in - the next beta. NOTE: The smooth renderer doesn't compile in - stand-alone mode anymore, but this should be fixed RSN.. - - - introduced convenience functions to more easily deal with glyph - images, see `include/ftglyph.h' for more details, as well as the - new demo program named `demos/src/ftstring.c' that demonstrates - its use - - - implemented FT_LOAD_NO_RECURSE in both the TrueType and Type 1 - drivers (this is required by the auto-hinter to improve its - results). - - - changed the raster interface, in order to allow client - applications to provide their own span-drawing callbacks. - However, only the smooth renderer supports this. See - `FT_Raster_Params' in the file `include/ftimage.h'. - - - fixed a small bug in FT_MulFix that caused incorrect transform - computation! - - - Note: The tutorial is out-of-date. - - -====================================================================== - -OLD CHANGES - 12-mar-2000 - - - changed the layout of configuration files : now, all ANSI - configuration files are located in - `freetype2/config'. System-specific over-rides can be placed in - `freetype2/config/'. - - - moved all configuration macros to `config/ftoption.h' - - - improvements in the Type 1 driver with AFM support - - - changed the fields in the FT_Outline structure : the old `flags' - array is re-named `tags', while all ancient flags are encoded into - a single unsigned int named `flags'. - - - introduced new flags in FT_Outline.flags (see - ft_outline_.... enums in `ftimage.h'). - - - changed outline functions to `FT_Outline_' syntax - - - added a smooth anti-alias renderer to the demonstration programs - - - added Mac graphics driver (thanks Just) - - - FT_Open_Face changed in order to received a pointer to a - FT_Open_Args descriptor.. - - - various cleanups, a few more API functions implemented (see - FT_Attach_File) - - - updated some docs - - -====================================================================== - -OLD CHANGES - 22-feb-2000 - - - introduced the `psnames' module. It is used to: - - o convert a Postscript glyph name into the equivalent Unicode - character code (used by the Type 1 driver(s) to synthesize on - the fly a Unicode charmap). - - o provide an interface to retrieve the Postscript names of the - Macintosh, Adobe Standard & Adobe Expert character codes. - (the Macintosh names are used by the SFNT-module postscript - names support routines, while the other two tables are used by - the Type 1 driver(s)). - - - introduced the `type1z' alternate Type 1 driver. This is a (still - experimental) driver for the Type 1 format that will ultimately - replace the one in `src/type1'. It uses pattern matching to load - data from the font, instead of a finite state analyzer. It works - much better than the `old' driver with `broken' fonts. It is also - much smaller (under 15 Kb). - - - the Type 1 drivers (both in `src/type1' and `src/type1z') are - nearly complete. They both provide automatic Unicode charmap - synthesis through the `psnames' module. No re-encoding vector is - needed. (note that they still leak memory due to some code - missing, and I'm getting lazy). - - Trivial AFM support has been added to read kerning information but - wasn't exactly tested as it should ;-) - - - The TrueType glyph loader has been seriously rewritten (see the - file `src/truetype/ttgload.c'. It is now much, much simpler as - well as easier to read, maintain and understand :-) Preliminary - versions introduced a memory leak that has been reported by Jack - Davis, and is now fixed.. - - - introduced the new `ft_glyph_format_plotter', used to represent - stroked outlines like Windows `Vector' fonts, and certain Type 1 - fonts like `Hershey'. The corresponding raster will be written - soon. - - - FT_New_Memory_Face is gone.

Because the list is important, it has been divided into -separate sections: - -Table Of Contents: - - I High-Level Interface (easier !) - II Directory Structure - III Glyph Image Formats - IV Build System - V Portability - VI Font Drivers - - ----------------------------------------------------------------------- - -High-Level Interface: - - The high-level API has been considerably simplified. Here is how: - - - resource objects have disappeared. this means that face objects - can now be created with a single function call (see FT_New_Face - and FT_Open_Face) - - - when calling either FT_New_Face & FT_Open_Face, a size object - and a glyph slot object are automatically created for the face, - and can be accessed through `face->glyph' and `face->size' if - one really needs to. In most cases, there's no need to call - FT_New_Size or FT_New_Glyph. - - - similarly, FT_Load_Glyph now only takes a `face' argument - (instead of a glyph slot and a size). Also, its `result' - parameter is gone, as the glyph image type is returned in the - field `face->glyph.format' - - - the list of available charmaps is directly accessible through - `face->charmaps', counting `face->num_charmaps' elements. Each - charmap has an 'encoding' field which specifies which known - encoding it deals with. Valid values are, for example: - - ft_encoding_unicode (for ASCII, Latin-1 and Unicode) - ft_encoding_apple_roman - ft_encoding_sjis - ft_encoding_adobe_standard - ft_encoding_adobe_expert - - other values may be added in the future. Each charmap still - holds its `platform_id' and `encoding_id' values in case the - encoding is too exotic for the current library - - ----------------------------------------------------------------------- - -Directory Structure: - - Should seem obvious to most of you: - - freetype/ - config/ -- configuration sub-makefiles - ansi/ - unix/ -- platform-specific configuration files - win32/ - os2/ - msdos/ - - include/ -- public header files, those to be included - directly by client apps - - src/ -- sources of the library - base/ -- the base layer - sfnt/ -- the sfnt `driver' (see the drivers section - below) - truetype/ -- the truetype driver - type1/ -- the type1 driver - shared/ -- some header files shared between drivers - - demos/ -- demos/tools - - docs/ -- documentation (a bit empty for now) - - ----------------------------------------------------------------------- - -Glyph Image Formats: - - Drivers are now able to register new glyph image formats within the - library. For now, the base layer supports of course bitmaps and - vector outlines, but one could imagine something different like - colored bitmaps, bi-color vectors or whatever else (Metafonts anyone - ??). - - See the file `include/ftimage.h'. Note also that the type - FT_Raster_Map is gone, and is now replaced by FT_Bitmap, which - should encompass all known bitmap types. - - Each new image format must provide at least one `raster', i.e. a - module capable of transforming the glyph image into a bitmap. It's - also possible to change the default raster used for a given glyph - image format. - - The default outline scan-converter now uses 128 levels of grays by - default, which tends to smooth many things. Note that the demo - programs have been updated significantly in order to display these.. - - ----------------------------------------------------------------------- - -Build system: - - You still need GNU Make to build the library. The build system has - been very seriously re-vamped in order to provide things like : - - - automatic host platform detection (reverting to 'config/ansi' if - it is not detected, with pseudo-standard compilation flags) - - - the ability to compile from the Makefiles with very different and - exotic compilers. Note that linking the library can be difficult - for some platforms. - - For example, the file `config/win32/lcclib.bat' is invoked by the - build system to create the `.lib' file with LCC-Win32 because its - librarian has too many flaws to be invoked directly from the - Makefile. - - Here's how it works: - - - the first time you type `make', the build system runs a series of - sub-makefiles in order to detect your host platform. It then - dumps what it found, and creates a file called `config.mk' in the - current directory. This is a sub-Makefile used to define many - important Make variables used to build the library. - - - the second time, the build system detects the `config.mk' then use - it to build the library. All object files go into 'obj' by - default, as well as the library file, but this can easily be - changed. - - Note that you can run `make setup' to force another host platform - detection even if a `config.mk' is present in the current - directory. Another solution is simply to delete the file, then - re-run make. - - Finally, the default compiler for all platforms is gcc (for now, - this will hopefully changed in the future). You can however specify - a different compiler by specifying it after the 'setup' target as - in: - - gnumake setup lcc on Win32 to use the LCC compiler - gnumake setup visualc on Win32 to use Visual C++ - - See the file `config//detect.mk' for a list of supported - compilers for your platforms. - - It should be relatively easy to write new detection rules files and - config.mk.. - - Finally, to build the demo programs, go to `demos' and launch GNU - Make, it will use the `config.mk' in the top directory to build the - test programs.. - - ----------------------------------------------------------------------- - -Portability: - - In the previous beta, a single FT_System object was used to - encompass all low-level operations like thread synchronisation, - memory management and i/o access. This has been greatly simplified: - - - thread synchronisation has been dropped, for the simple reason - that the library is already re-entrant, and that if you really - need two threads accessing the same FT_Library, you should - really synchronize access to it yourself with a simple mutex. - - - memory management is performed through a very simple object - called `FT_Memory', which really is a table containing a table - of pointers to functions like malloc, realloc and free as well - as some user data (closure). - - - resources have disappeared (they created more problems than they - solved), and i/o management have been simplified greatly as a - result. Streams are defined through FT_Stream objects, which - can be either memory-based or disk-based. - - Note that each face has its own stream, which is closed only - when the face object is destroyed. Hence, a function like - TT_Flush_Face in 1.x cannot be directly supported. However, if - you really need something like this, you can easily tailor your - own streams to achieve the same feature at a lower level (and - use FT_Open_Face instead of FT_New_Face to create the face). - - See the file `include/ftsystem.h' for more details, as well as the - implementations found in `config/unix' and `config/ansi'. - - ----------------------------------------------------------------------- - -Font Drivers: - - The Font Driver interface has been modified in order to support - extensions & versioning. - - - The list of the font drivers that are statically linked to the - library at compile time is managed through a new configuration file - called `config//ftmodule.h'. - - This file is autogenerated when invoking `make modules'. This - target will parse all sub-directories of 'src', looking for a - `module.mk' rules file, used to describe the driver to the build - system. - - Hence, one should call `make modules' each time a font driver is - added or removed from the `src' directory. - - Finally, this version provides a `pseudo-driver' in `src/sfnt'. - This driver doesn't support font files directly, but provides - services used by all TrueType-like font drivers. Hence, its code is - shared between the TrueType & OpenType font formats, and possibly - more formats to come if we're lucky.. - - ----------------------------------------------------------------------- - -Extensions support: - - The extensions support is inspired by the one found in 1.x. - - Now, each font driver has its own `extension registry', which lists - which extensions are available for the font faces managed by the - driver. - - Extension ids are now strings, rather than 4-byte tags, as this is - usually more readable. - - Each extension has: - - some data, associated to each face object - - an interface (table of function pointers) - - An extension that is format-specific should simply register itself - to the correct font driver. Here is some example code: - - // Registering an extensions - // - FT_Error FT_Init_XXXX_Extension( FT_Library library ) - { - FT_DriverInterface* tt_driver; - - driver = FT_Get_Driver( library, "truetype" ); - if (!driver) return FT_Err_Unimplemented_Feature; - - return FT_Register_Extension( driver, &extension_class ); - } - - - // Implementing the extensions - // - FT_Error FT_Proceed_Extension_XXX( FT_Face face ) - { - FT_XXX_Extension ext; - FT_XXX_Extension_Interface ext_interface; - - ext = FT_Get_Extension( face, "extensionid", &ext_interface ); - if (!ext) return error; - - return ext_interface->do_it(ext); - } - ------------------------------------------------------------------------- - -Copyright (C) 2000-2021 by -David Turner, Robert Wilhelm, and Werner Lemberg. - -This file is part of the FreeType project, and may only be used, -modified, and distributed under the terms of the FreeType project -license, LICENSE.TXT.

Configuration macros - - The file `include/freetype/config/ftoption.h' contains a list of - commented configuration macros that can be toggled by developers to - indicate which features should be active while building the library. - - These options range from debug level to availability of certain - features, like native TrueType hinting through a bytecode - interpreter. - - We invite you to read this file for more information. You can - change the file's content to suit your needs, or override it with - one of the techniques described below. - - -II. Modules list - - If you use GNU make please edit the top-level file `modules.cfg'. - It contains a list of available FreeType modules and extensions to - be compiled. Change it to suit your own preferences. Be aware that - certain modules depend on others, as described in the file. GNU - make uses `modules.cfg' to generate `ftmodule.h' (in the object - directory). - - If you build FreeType in a directory separate from the source files, - put your customized `modules.cfg' in that directory; that way you - can keep the source files `clean'. - - If you don't use GNU make you have to manually edit the file - `include/freetype/config/ftmodule.h' (which is *not* used with if - compiled with GNU make) to add or remove the drivers and components - you want to compile into the library. See `INSTALL.ANY' for more - information. - - -III. System interface - - FreeType's default interface to the system (i.e., the parts that - deal with memory management and i/o streams) is located in - `src/base/ftsystem.c'. - - The current implementation uses standard C library calls to manage - memory and to read font files. It is however possible to write - custom implementations to suit specific systems. - - To tell the GNU Make-based build system to use a custom system - interface, you have to define the environment variable FTSYS_SRC to - point to the relevant implementation: - - on Unix: - - ./configure - export FTSYS_SRC=foo/my_ftsystem.c - make - make install - - on Windows: - - make setup - set FTSYS_SRC=foo/my_ftsystem.c - make - - -IV. Overriding default configuration and module headers - - It is possible to override the default configuration and module - headers without changing the original files. There are three ways - to do that: - - - 1. With GNU make - - [This is actually a combination of method 2 and 3.] - - Just put your custom `ftoption.h' file into the objects directory - (normally `/objs' if you build in the source tree, or the - directory where you invoke configure if you build in a separate - directory), which GNU make prefers over the standard location. No - action is needed for `ftmodule.h' because it is generated - automatically in the objects directory. - - 2. Using the C include path - - Use the C include path to ensure that your own versions of the - files are used at compile time when the lines - - #include FT_CONFIG_OPTIONS_H - #include FT_CONFIG_MODULES_H - - are compiled. Their default values being - and , you - can do something like: - - custom/ - config/ - ftoption.h => custom options header - ftmodule.h => custom modules list - - include/ => normal FreeType 2 include - ... - - then change the C include path to always give the path to `custom' - before the FreeType 2 `include'. - - - 3. Redefining FT_CONFIG_OPTIONS_H and FT_CONFIG_MODULES_H - - Another way to do the same thing is to redefine the macros used to - name the configuration headers. To do so, you need a custom - `ft2build.h' whose content can be as simple as: - - #ifndef FT2_BUILD_MY_PLATFORM_H_ - #define FT2_BUILD_MY_PLATFORM_H_ - - #define FT_CONFIG_OPTIONS_H - #define FT_CONFIG_MODULES_H - - #include - - #endif /* FT2_BUILD_MY_PLATFORM_H_ */ - - Place those files in a separate directory, e.g., - - custom/ - ft2build.h => custom version described above - my-ftoption.h => custom options header - my-ftmodule.h => custom modules list header - - and change the C include path to ensure that `custom' is always - placed before the FT2 `include' during compilation. - ----------------------------------------------------------------------- - -Copyright (C) 2003-2021 by -David Turner, Robert Wilhelm, and Werner Lemberg. - -This file is part of the FreeType project, and may only be used, -modified, and distributed under the terms of the FreeType project -license, LICENSE.TXT.

Configuration macros ------------------------ - -There are several ways to enable debugging features in a FreeType 2 -builds. This is controlled through the definition of special macros -located in the file `ftoption.h'. The macros are: - - - FT_DEBUG_LEVEL_ERROR - - #define this macro if you want to compile the `FT_ERROR' macro - calls to print error messages during program execution. This does - not stop the program. Very useful to spot invalid fonts during - development and to code workarounds for them. - - FT_DEBUG_LEVEL_TRACE - - #define this macro if you want to compile both macros `FT_ERROR' - and `FT_TRACE'. This also includes the variants `FT_TRACE0', - `FT_TRACE1', `FT_TRACE2', ..., `FT_TRACE7'. - - The trace macros are used to send debugging messages when an - appropriate `debug level' is configured at runtime through the - `FT2_DEBUG' environment variable (more on this later). - - FT_DEBUG_MEMORY - - If this macro is #defined, the FreeType engine is linked with a - small but effective debugging memory manager that tracks all - allocations and frees that are performed within the font engine. - - When the `FT2_DEBUG_MEMORY' environment variable is defined at - runtime, a call to `FT_Done_FreeType' dumps memory statistics, - including the list of leaked memory blocks and optionally with the - source locations where these were allocated. It is always a very - good idea to define this in development builds. This works with - _any_ program linked to FreeType, but requires a big deal of - memory (the debugging memory manager never frees the blocks to the - heap in order to detect double frees). - - When `FT2_DEBUG_MEMORY' isn't defined at runtime, the debugging - memory manager is ignored, and performance is unaffected. - - FT_DEBUG_LOGGING - - #define this macro for enhanced logging support; it automatically - sets `FT_DEBUG_LEVEL_TRACE' and `FT_DEBUG_LEVEL_ERROR'. - - If defined, `FT_TRACE' and `FT_ERROR' can send tracing and - debugging messages to a file. The location of the log file has to - be set with the `FT_LOGGING_FILE' environment variable (more on - this later). - - The main enhancements are the possibility of logging the time and - the name of the `FT_COMPONENT' macro together with the affected - `FT_TRACE' or `FT_ERROR' calls. See below how to activate this in - the `FT2_DEBUG' environment variable. - - -II. Debugging macros --------------------- - -Several macros can be used within the FreeType sources to help -debugging its code: - - - 1. FT_ERROR(( ... )) - - This macro is used to send debug messages that indicate relatively - serious errors (like broken font files) without stopping the - execution of the running program. Its code is compiled only when - either `FT_DEBUG_LEVEL_ERROR' or `FT_DEBUG_LEVEL_TRACE' are - defined in `ftoption.h'. - - Note that you have to use a printf-like signature, but with double - parentheses, like in - - FT_ERROR(( "your %s is not %s\n", "foo", "bar" )); - - - 2. FT_ASSERT( condition ) - - This macro is used to check strong assertions at runtime. If its - condition isn't TRUE, the program aborts with a panic message. - Its code is compiled when either `FT_DEBUG_LEVEL_ERROR' or - `FT_DEBUG_LEVEL_TRACE' are defined. You don't need double - parentheses here. Example: - - FT_ASSERT( ptr != NULL ); - - - 3. FT_TRACE( level, (message...) ) - - The `FT_TRACE' macro is used to send general-purpose debugging - messages during program execution. This macro uses an *implicit* - macro named `FT_COMPONENT', which names the current FreeType - component being run. - - The developer should always define `FT_COMPONENT' as appropriate, - for example as in - - #undef FT_COMPONENT - #define FT_COMPONENT io - - The value of the `FT_COMPONENT' macro is one of the component - names defined in the internal file `internal/fttrace.h'. If you - modify the FreeType source code and insert a new `FT_COMPONENT' - macro, you must register it in `fttrace.h'. If you insert or - remove many trace macros, you can test for undefined or unused - trace macros with the script `src/tools/chktrcmp.py'. - - Each such component is assigned a `debug level', ranging from - value 0 to 7, through the use of the `FT2_DEBUG' environment - variable (described below) when a program linked with FreeType - starts. - - When `FT_TRACE' is called, its level is compared to the one of the - corresponding component. Messages with trace levels *higher* than - the corresponding component level are filtered out and never - printed. This means that trace messages with level 0 are always - printed, those with level 2 are only printed when the component - level is *at least* 2, etc. - - The second parameter to `FT_TRACE' must contain parentheses and - corresponds to a printf-like call, as in - - FT_TRACE( 2, ( "your %s is not %s\n", "foo", "bar" ) ) - - The shortcut macros `FT_TRACE0', `FT_TRACE1', `FT_TRACE2', ..., - `FT_TRACE7' can be used with constant level indices, and are much - cleaner to use, as in - - FT_TRACE2(( "your %s is not %s\n", "foo", "bar" )); - - -III. Environment variables --------------------------- - -The following environment variables control debugging output and -behaviour of FreeType at runtime. - - - FT2_DEBUG - - This variable is only used when FreeType is built with - `FT_DEBUG_LEVEL_TRACE' defined. It contains a list of component - level definitions, following this format: - - component1:level1 component2:level2 component3:level3 ... - - where `componentX' is the name of a tracing component, as defined - in `fttrace.h'. `levelX' is the corresponding level to use at - runtime. - - `any' is a special component name that is interpreted as `any/all - components'. For example, the following definitions - - set FT2_DEBUG=any:2 memory:5 io:4 (on Windows) - export FT2_DEBUG="any:2 memory:5 io:4" (on Linux with bash) - - both stipulate that all components should have level 2, except for - the memory and io components, which are set to the trace levels 5 - and 4, respectively. - - If `FT_DEBUG_LOGGING' is defined, two more options are available. - - * -v: Print also the name of FreeType's component from which the - current log is produced, together with the tracing level. - - * -t: Print also the time. - - Here are some examples how the output might look like. - - FT2_DEBUG="any:7 memory:5 -vt" - - => [20:32:02:44969 ttload:2] table directory loaded - - FT2_DEBUG="any:7 memory:5 -t" - - => [20:32:02:44969] table directory loaded - - FT2_DEBUG="any:7 memory:5 -v" - - => [ttload:2] table directory loaded - - - FT_LOGGING_FILE - - This variable is only used if FreeType is built with the - `FT_DEBUG_LOGGING' macro defined. It contains the path to the - file where the user wants to put his log file. If it is not set, - FreeType uses stderr. - - Examples: - - On UNIX-like systems with bash: - export FT_LOGGING_FILE="/tmp/freetype2.log" - - On Windows: - set FT_LOGGING_FILE=C:\Users\AppData\Local\Temp\freetype2.log - - - FT2_DEBUG_MEMORY - - This environment variable, when defined, tells FreeType to use a - debugging memory manager that tracks leaking memory blocks as well - as other common errors like double frees. It is also capable of - reporting _where_ the leaking blocks were allocated, which - considerably saves time when debugging new additions to the - library. - - This code is only compiled when FreeType is built with the - `FT_DEBUG_MEMORY' macro #defined in `ftoption.h' though, it is - ignored in other builds. - - - FT2_ALLOC_TOTAL_MAX - - This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. It - allows you to specify a maximum heap size for all memory - allocations performed by FreeType. This is very useful to test - the robustness of the font engine and programs that use it in - tight memory conditions. - - If it is undefined, or if its value is not strictly positive, no - allocation bounds are checked at runtime. - - - FT2_ALLOC_COUNT_MAX - - This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. It - allows you to specify a maximum number of memory allocations - performed by FreeType before returning the error - `FT_Err_Out_Of_Memory'. This is useful for debugging and testing - the engine's robustness. - - If it is undefined, or if its value is not strictly positive, no - allocation bounds are checked at runtime. - - - FT2_KEEP_ALIVE - - This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. - `Keep alive' means that freed blocks aren't released to the heap. - This is useful to detect double-frees or weird heap corruption, - reporting the source code location of the original allocation and - deallocation in case of a problem. It uses large amounts of - memory, however. - - If it is undefined, or if its value is not strictly positive, - freed blocks are released at runtime. - - -IV. Additional Capabilities with `FT_DEBUG_LOGGING' ---------------------------------------------------- - -If `FT_DEBUG_LOGGING' is defined, four APIs are available to provide -additional debugging support. Use - - #include - -to access them. - - FT_Trace_Set_Level( const char* level ) - - By default, FreeType uses the tracing levels set in the - `FT2_DEBUG' environment variable. Use this function to override - the value with `level'. Use value `NULL' to disable tracing. - - FT_Trace_Set_Default_Level(): - - Reset the tracing levels to the default value, i.e., the value of - the `FT2_DEBUG' environment variable or no tracing if not set. - - FT_Set_Log_Handler( ft_custom_log_handler handler ): - - Use `handler' as a custom handler for formatting tracing and error - messages. The `ft_custom_log_handler' typedef has the following - prototype. - - void - (*ft_custom_log_handler)( const char* ft_component, - const char* fmt, - va_list args ); - - `ft_component' is the current component like `ttload', `fmt' is the - first argument of `FT_TRACE' or `FT_ERROR', and `args' holds the - remaining arguments. - - FT_Set_Default_Log_Handler(): - - Reset the log handler to the default version. - - ------------------------------------------------------------------------- - -Copyright (C) 2002-2021 by -David Turner, Robert Wilhelm, and Werner Lemberg. - -This file is part of the FreeType project, and may only be used, -modified, and distributed under the terms of the FreeType project -license, LICENSE.TXT.

However, if a -header needs to be added, note the following correspondence to HTML tags: - -* Section title on top of the page is `H1`. -* Sub-section titles are `H2`. -* Parts of sub-sections are `H4`. -* Any header added will be visible in the Table of Contents (TOC) of - the page. - - -Emphasis --------- - -* Use `_underscores_` for italics. -* Use `**double asterisks**` for bold. - -Although the other notations (double underscore for bold, single -asterisk for italics) are supported, it is recommended to use the -above for consistency. - -Note that there may be cases where having two asterisks or underscores -in a line may lead to text being picked up as italics or bold. -Although unintentional, this is correct markdown behavior. - -For inline code, wrap the sequence with backticks (see below). This -renders symbols correctly without modifications. If a symbol is -absolutely required outside of an inline code block or code sequence, -escape it with a backslash (like `\*` or `\_`). - - -Lists ------ - -Unordered lists can be created with asterisks: - - * Unordered list items can use asterisks. - * Another list item. - -Ordered lists start with numbers: - - 1. This is an ordered list item. - 2. Brackets after numbers won't work. - -To continue a list over multiple paragraphs, indent them with at least -four spaces. For example: - - 1. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. - Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, - viverra nec, fringilla in, laoreet vitae, risus. - - Donec sit amet nisl. Aliquam semper ipsum sit amet velit. - Suspendisse id sem consectetuer libero luctus adipiscing. - - 2. This is the second list item. - - This paragraph is not a part of the list. - -More information on lists in markdown is available at - - https://daringfireball.net/projects/markdown/syntax#list - - -Cross-references ----------------- - -Other sub-sections can be linked with the `@` symbol: - - @description: - While FreeType's CFF driver doesn't expose API functions by - itself, it is possible to control its behaviour with - @FT_Property_Set and @FT_Property_Get. - -If a field in the `values` table of another sub-section is linked, the -link leads to its parent sub-section. - - -Links and Images ----------------- - -All URLs are converted to links in the HTML documentation. - -Markdown syntax for links and images are fully supported. - - -Inline Code ------------ - -To indicate a span of code, wrap it with backtick quotes (`` ` ``): - - Use the `printf()` function. - -Cross-references, markdown, and html styling do not work in inline code -sequences. - - -Code and Syntax Highlighting ----------------------------- - -Blocks of code are fenced by lines with three back-ticks `` ``` `` -followed by the language name, if any (used for syntax highlighting), -as demonstrated in the following example. - - ```c - x = y + z; - if ( zookoo == 2 ) - { - foobar(); - } - ``` - -Note that the indentation of the opening line and the closing line -must be exactly the same. The code sequence itself should have a -larger indentation than the surrounding back-ticks. - -Like inline code, markdown and html styling is *not* supported inside -code blocks. - - -Tables ------- - -Tables are used to list values, input, and other fields. The FreeType -Flavored Markdown adopts a simple approach to tables with two columns, -or field definition tables. - -Field definition names may contain alphanumeric, underscore, and the -`.` characters. This is followed by `::`. The following lines are -the second column of the table. A field definition ends with the -start of another field definition, or a markup tag. - - @Input: - pathname :: - A path to the font file. - - face_index :: - See @FT_Open_Face for a detailed description of this - parameter. - - -Non-breaking Space ------------------- - -A tilde can be used to create a non-breaking space. The example - - The encoding value~0 is reserved. - -is converted to - - The encoding value 0 is reserved. - - ----------------------------------------------------------------------- - -Copyright (C) 2018-2021 by -Nikhil Ramakrishnan, David Turner, Robert Wilhelm, and Werner Lemberg. - -This file is part of the FreeType project, and may only be used, -modified, and distributed under the terms of the FreeType project -license, LICENSE.TXT.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Prerequisites and dependencies -================================= - - FreeType is a low level C library that only depends on the standard - C library with very few platform-dependent optimizations utilized at - build time. System libraries, such as zlib, Gzip, bzip2, Brotli, - and libpng, might be used to handle compressed fonts or decode - embedded PNG glyphs. - - FreeType auto-configuration scripts should be able to detect the - prerequisites if the necessary headers are available at the default - locations.

Normally, you don't - need to change anything. - - Applications have very limited control over FreeType's behaviour at - run-time; look at the documentation of function `FT_Property_Set'. - - -II. Normal installation and upgrades -==================================== - - 1. Unix and Unix-like systems - - This also includes MacOS, Cygwin, MinGW + MSYS, Mingw-w64 + MSYS2, - and possibly other, similar environments. - - Please read `INSTALL.UNIX' to install or upgrade FreeType 2 on a - Unix system.

Before reading this document, please consult the -file `INSTALL.UNIX' for required tools and the basic self-building -procedure. - - - 1. Required Tools - ----------------- - - For self-building the FreeType library on a Unix system, GNU Make - 3.81 or newer is required. `INSTALL.UNIX' contains hints how to - check the installed `make'. - - The GNU C compiler to cross-build the target system is required. - Currently, using a non-GNU cross compiler is untested. The cross - compiler is expected to be installed with a system prefix. For - example, if your building system is FreeBSD/i386 and the target - system is Linux/MIPS, the cross compiler should be installed with - the name `mips-ip22-linuxelf-gcc'. - - A C compiler for a self-build is required also, to build a tool - (`apinames') that is executed during the build procedure. Non-GNU - self compilers are acceptable, but such a setup is untested. - - - 2. Configuration - ---------------- - - 2.1. Building and target system - - To configure a cross-build, the options `--host=' and - `--build=' must be passed to the `configure' script. - For example, if your build system is FreeBSD/i386 and the target - system is Linux/MIPS, say - - ./configure \ - --build=i386-unknown-freebsd \ - --host=mips-ip22-linuxelf \ - [other options] - - It should be noted that `--host=' specifies the system - where the built binaries will be executed, not the system where - the build actually happens. Older versions of GNU autoconf use - the option pair `--host=' and `--target='. This is broken and - doesn't work. Similarly, an explicit CC specification like - - env CC=mips-ip22-linux-gcc ./configure # BAD - - or - - env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD - - doesn't work either; such a configuration confuses the - `configure' script while trying to find the cross and native C - compilers. - - - 2.2. The prefix to install FreeType2 - - Setting `--prefix=' properly is important. The prefix - to install FreeType2 is written into the `freetype-config' - script and `freetype2.pc' configuration file. - - If the built FreeType 2 library is used as a part of the - cross-building system, the prefix is expected to be different - from the self-building system. For example, a configuration - with `--prefix=/usr/local' installs binaries into the - system-wide `/usr/local' directory, which then can't be executed - due to the incorrect architecture. This causes confusion in - configuration of all applications that use FreeType2. Instead, - use a prefix to install the cross-build into a separate system - tree, for example, `--prefix=/usr/local/mips-ip22-linux/'. - - On the other hand, if the built FreeType 2 library is used as a - part of the target system, the prefix to install should reflect - the file system structure of the target system. - - - 2.3. Library dependencies - - FreeType normally depends on external libraries like `libpng' or - `libharfbuzz'. The easiest case is to deactivate all such - dependencies using the `--without-XXX' configuration options. - However, if you want to use those libraries, you should ensure - that they are available both on the target system and as - (cross-compiled) libraries on the build system. - - FreeType uses `pkg-config' to find most of the libraries; the - other libraries it links to are expected in the standard system - directories. Since the default pkg-config's meta-information - files (like `harfbuzz.pc') of the build platform don't work, use - one of the two possible solutions below. - - o Use pkg-config's meta-information files that are adjusted to - cross-compile and cross-link with the target platform's - libraries. Make sure those files are found before the build - system's default files. Example: - - ./configure \ - --build=i386-unknown-freebsd \ - --host=mips-ip22-linuxelf \ - PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \ - [other options] - - See the manpage of `pkg-config' for more details. - - o Set variables like LIBPNG_LIBS as additional options to the - `configure' script, overriding the values `pkg-config' would - provide. `configure --help' shows the available environment - variables. Example: - - ./configure \ - --build=i386-unknown-freebsd \ - --host=mips-ip22-linuxelf \ - LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \ - LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \ - [other options] - - - 3. Building command - ------------------- - - If the configuration finishes successfully, invoking GNU make - builds FreeType2. Just say - - make - - or - - gmake - - depending on the name the GNU make binary actually has. - - - 4. Installation - --------------- - - Saying - - make install - - as usual to install FreeType2 into the directory tree specified by - the argument of the `--prefix' option. - - As noted in section 2.2, FreeType2 is sometimes configured to be - installed into the system directory of the target system, and - should not be installed in the cross-building system. In such - cases, the make variable `DESTDIR' is useful to change the root - directory in the installation. For example, after - - make DESTDIR=/mnt/target_system_root/ install - - the built FreeType2 library files are installed into the directory - `/mnt/target_system_root//lib'. - - - 5.

Build the library - -------------------- - - The auto-detection/setup phase should have copied a file in the - current directory, called `./config.mk'.

[It has also generated a file called - `ftmodule.h' in the objects directory (which is normally - `/objs/'); please read the file `docs/CUSTOMIZE' for - customization of FreeType.] - - To launch the build, simply invoke GNU Make again: The top - Makefile will detect the configuration file and run the build with - it.

The solution is to cast to `(void*)' instead which - is the generic pointer type, so the compiler knows that it should - make no strict-aliasing assumption on `x'. But the problem with - `(void*)x' is that seems like in C++, unlike C, `void*' is not a - generic pointer type and assigning `void*' to `Bar*' without a cast - causes an error.
