Error handling or setting face->root is done later in - `sfnt_load_face'. - - * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. - Mac bitmap-only fonts are not scalable. - Check that `face->header.Units_Per_EM' is not zero. - (LOAD_, LOADM_): Emit pretty trace messages. - - * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics - from `eblc'. - - * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c - (load_format_20, load_format_25, tt_face_get_ps_name): Use - face->max_profile.numGlyphs, instead of face->root.num_glyphs. - -2006-02-14 Werner Lemberg - - * include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in - documentation that negative strength values are possible. - Give an example call. - - * include/freetype/freetype.h (FT_GlyphSlotRec): Improve - documentation of `outline' field. - - * src/sfnt/sfobjc.s: Inckude FT_INTERNAL_DEBUG_H. - * src/sfnt/sfdriver.c: Include ttmtx.h. - - * src/autofit/afcjk.c: Include aftypes.h and aflatin.h. - -2006-02-14 Chia-I Wu - - * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo. - -2006-02-14 Chia-I Wu - - * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply - return error if table is missing. - Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'. - - * src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics - tables.

In this pass, we want to treat the - font directory (offset table and table directory) as a normal table - like the others. This also means that TTCs are no longer recognized - there but in `init_face'. - - * include/freetype/internal/sfnt.h (SFNT_Interface), - src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are - combined and renamed to `load_font_dir'. - - * src/sfnt/ttload.h, src/sfnt/ttload.c: - s/sfnt_dir_check/check_table_dir/. - `sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'. - `tt_face_load_sfnt_header' and `tt_face_load_directory' are combined - and renamed to `tt_face_load_font_dir'. - - * src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here. - -2006-02-13 Chia-I Wu - - Clean up the SFNT_Interface. Table loading functions are now named - after the tables' tags; `hdmx' is TrueType-specific and thus the - code is moved to the truetype module; `get_metrics' is moved here - from the truetype module so that the code can be shared with the cff - module. - - This pass involves no real changes. That is, the code is moved - verbatim mostly. The only exception is the return value of - `tt_face_get_metrics'. - - * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, - src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, - src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, - src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. - - * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files. Metrics-related - tables' loading and parsing code is moved to here. - Move `tt_face_get_metrics' here from the truetype module. The - return value is changed from `void' to `FT_Error'. - - * include/freetype/internal/fttrace.h: New trace: ttmtx. - - * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and - parsing code is moved here. - New function `tt_face_load_prep' split from `tt_face_load_fpgm'. - `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. - - * src/cff/cffgload.c, src/cff/cffobjs.c: Update. - - * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update. - -2006-02-11 Chia-I Wu - - * src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug... - - * src/autofit/aflatin.c (af_latin_metrics_init_widths): Use - AF_LatinMetricsRec as the dummy metrics because we cast the metrics - to it later in `af_latin_hints_link_segments'. - -2006-02-11 Chia-I Wu - - * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define - to enable autofit CJK script support. (#define'd by default.) - - * src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro. - - * src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure - that `edge_distance_threshold' is always set. - (af_latin_hints_link_segments): Potential divide-by-zero bug. - Use latin constant in the scoring formula. - - * src/autofit/afcjk.c: Minor updates due to the above three changes. - - * docs/TODO, docs/CHANGES: Updated. - -2006-02-09 Chia-I Wu - - Introduce experimental autofit CJK module based on akito's autohint - patch.

It is -based on the version found in the sourcecode of ttf.library 0.83b for -FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com, -http://ragriffi.home.sprynet.com). - -You will also need the latest include files and amiga.lib from the -Amiga web site (http://www.amiga.com/3.9/download/NDK3.9.lha) for -AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up. - -To use it, call "smake assign" and then "smake" from the builds/amiga -directory. The results are: - -- A link library "ft2_680x0.lib" (where x depends on the setting of - the CPU entry in the smakefile) containing all FreeType2 parts - except of the init code, debugging code, and the system interface - code. - -- ftsystem.o, an object module containing the standard version of the - system interface code which uses fopen() fclose() fread() fseek() - ftell() malloc() realloc() and free() from lib:sc.lib (not pure). - -- ftsystempure.o, an object module containing the pure version of the - system interface code which uses Open() Close() Read() Seek() - ExamineFH() AsmAllocPooled() AsmFreePooled() etc. This version can - be used in both normal programs and in Amiga run-time shared system - librarys (can be linked with lib:libinit.o, no copying of DATA and - BSS hunks for each OpenLibrary() necessary). Source code is in - src/base/ftsystem.c. - -- ftdebug.o, an object module containing the standard version of the - debugging code which uses vprintf() and exit() (not pure). - Debugging can be turned on in FT:include/freetype/config/ftoption.h - and with FT_SetTraceLevel(). - -- ftdebugpure.o, an object module containing the pure version of the - debugging code which uses KVPrintf() from lib:debug.lib and no - exit(). For debugging of Amiga run-time shared system libraries. - Source code is in src/base/ftdebug.c. - -- NO ftinit.o. Because linking with a link library should result in - linking only the needed object modules in it, but standard - ftsystem.o would force ALL FreeType2 modules to be linked to your - program, I decided to use a different scheme: You must #include - FT:src/base/ftinit.c in your sourcecode and specify with #define - statements which modules you need. See - include/freetype/config/ftmodule.h. - - -To use in your own programs: - -- Insert the #define and #include statements from top of - include/freetype/config/ftmodule.h in your source code and uncomment - the #define statements for the FreeType2 modules you need. - -- You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for - calling the FreeType2 functions, because the link library and the - object files are compiled with PARAMETERS=BOTH. - -- "smake assign" (assign "FT:" to the FreeType2 main directory). - -- Compile your program. - -- Link with either ftsystem.o or ftsystempure.o, if debugging enabled - with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with - ft2_680x0.lib as link library. - - -To adapt to other compilers: - -- The standard ANSI C maximum length of 31 significant characters in - identifiers is not enough for FreeType2. Check if your compiler has - a minimum length of 40 significant characters or can be switched to - it. "idlen=40" is the option for SAS/C. Setting #define - HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested). - -- Make sure that the include directory in builds/amiga is searched - before the normal FreeType2 include directory, so you are able to - replace problematic include files with your own version (same may be - useful for the src directory). - -- An example of how to replace/workaround a problematic include file - is include/config/ftconfig.h; it changes a #define that would - prevent SAS/C from generating XDEF's where it should do that and - then includes the standard FreeType2 include file. - -Local Variables: -coding: latin-1 -End: diff --git a/external/freetype-2.4.11/builds/amiga/include/freetype/config/ftconfig.h b/external/freetype-2.4.11/builds/amiga/include/freetype/config/ftconfig.h deleted file mode 100644 index c2c2ac8dbb..0000000000 --- a/external/freetype-2.4.11/builds/amiga/include/freetype/config/ftconfig.h +++ /dev/null @@ -1,55 +0,0 @@ -/***************************************************************************/ -/* */ -/* ftconfig.h */ -/* */ -/* Amiga-specific configuration file (specification only). */ -/* */ -/* Copyright 2005, 2006, 2007 by */ -/* Werner Lemberg and Detlef Wrkner. */ -/* */ -/* 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.

Apple MPW - -------------- - - Following C compilers are tested: - - m68k target: Apple SC 8.9.0d3e1 - ppc target: Apple MrC 5.0.0d3c1 - - The final MPW-GM (official release on 1999/Dec) is too - old and cannot compile FreeType, because bundled C - compilers cannot search header files in sub directories. - Updating by the final MPW-PR (pre-release on 2001/Feb) - is required. - - Required files are downloadable from: - - http://developer.apple.com/tools/mpw-tools/index.html - - Also you can find documents how to update by MPW-PR. - - Python is required to restore MPW makefiles from the - skeltons. Python bundled to Mac OS X is enough. For - classic MacOS, MacPython is available: - - http://homepages.cwi.nl/~jack/macpython/ - - MPW requires all files are typed by resource fork. - ResEdit bundled to MPW is enough. In Mac OS X, - /Developer/Tools/SetFile of DevTool is useful to - manipulate from commandline. - - 2-2. Metrowerks CodeWarrior - --------------------------- - - XML project file is generated and tested by - CodeWarrior 9.0. Older versions are not tested - at all. At present, static library for ppc target - is available in the project file. - - -3. How to build ---------------- - - 3-1. Apple MPW - -------------- - Detailed building procedure by Apple MPW is - described in following. - - 3-1-1. Generate MPW makefiles from the skeltons - ------------------------------------------------ - - Here are 4 skeltons for following targets are - included. - - - FreeType.m68k_far.make.txt - Ancient 32bit binary executable format for - m68k MacOS: System 6, with 32bit addressing - mode (far-pointer-model) So-called "Toolbox" - API is used. - - - FreeType.m68k_cfm.make.txt - CFM binary executable format for m68k MacOS: - System 7. So-called "Toolbox" API is used. - - - FreeType.ppc_classic.make.txt - CFM binary executable format for ppc MacOS: - System 7, MacOS 8, MacOS 9. So-called "Toolbox" - API is used. - - - FreeType.ppc_carbon.make.txt - CFM binary executable format for ppc MacOS: - MacOS 9. Carbon API is used. - - At present, static library is only supported, - although targets except of m68k_far are capable - to use shared library. - - MPW makefile syntax uses 8bit characters. To keep - from violating them during version control, here - we store skeltons in pure ASCII format. You must - generate MPW makefile by Python script ascii2mpw.py. - - In Mac OS X terminal, you can convert as: - - python builds/mac/ascii2mpw.py \ - < builds/mac/FreeType.m68k_far.make.txt \ - > FreeType.m68k_far.make - - The skeltons are designed to use in the top - directory where there are builds, include, src etc. - You must name the generated MPW makefile by removing - ".txt" from source skelton name. - - 3-1-2. Add resource forks to related files - ------------------------------------------ - - MPW's Make and C compilers cannot recognize files - without resource fork. You have to add resource - fork to the files that MPW uses. In Mac OS X - terminal of the system, you can do as: - - find . -name '*.[ch]' -exec \ - /Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \; - - find . -name '*.make' -exec \ - /Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \; - - - 3-1-3. Open MPW shell and build - ------------------------------- - - Open MPW shell and go to the top directory that - FreeType sources are extracted (MPW makefile must - be located in there), from "Set Directory" in - "Directory" menu. - - Choose "Build" from "Build" menu, and type the - name of project by removing ".make" from MPW - makefile, as: FreeType.m68k_far - - If building is successfully finished, you can find - built library in objs/ directory. - - - 3-2. Metrowerks CodeWarrior - --------------------------- - - Detailed building procedure by Metrowerks - CodeWarrior (CW) 9.0 is described in following. - - 3-2-1. Import XML project file - ------------------------------ - - CW XML project file is not ready for double- - click. Start CodeWarrior IDE, and choose - "Import project" in "File" menu. Choose XML - project file: builds/mac/ftlib.prj.xml. - In next, you will be asked where to save CW - native project file: you must choose - "builds/mac/ftlib.prj". The project file is - designed with relative path from there. After - CW native project file is generated, it is - automatically loaded, small project window - titled "ftlib.prj" is displayed. - - 3-2-2. Building - --------------- - Choose "Make" from "Project" menu. If building - is successfully finished, you can find built - library at objs/FreeTypeLib. - -4. TODO -------- - - 4-1. All modules should be included - ----------------------------------- - - At present, MPW makefiles and CW project file are - just updated versions of these by Leonard. Some - modules are added after the last maintenance, they - are not included. - - 4-2. Working test with ftdemos - ------------------------------ - - At present, MPW makefiles and CW project file can - build FreeType for classic MacOS. But their working - behaviours are not tested at all. Building ftdemos - for classic MacOS and working test is required. - - 4-3. Porting Jam onto MPW - ------------------------- - - FreeType uses Jam (and FT-Jam) for unified cross- - platform building tool. At present, Jam is not ported - to MPW. To update classic MacOS support easily, - building by Jam is expected on MPW. - - -APPENDIX I ----------- - - A-1. Framework dependencies - --------------------------- - - src/base/ftmac.c adds two Mac-specific features to - FreeType. These features are based on MacOS libraries. - - * accessing resource-fork font - The fonts for classic MacOS store their graphical data - in resource forks which cannot be accessed via ANSI C - functions. FreeType2 provides functions to handle such - resource fork fonts, they are based on File Manager - framework of MacOS. In addition, HFS and HFS+ file - system driver of Linux is supported. Following - functions are for this purpose. - - FT_New_Face_From_Resource() - FT_New_Face_From_FSSpec() - FT_New_Face_From_FSRef() - - * resolving font name to font file - The font menu of MacOS application prefers font name - written in FOND resource than sfnt resource. FreeType2 - provides functions to find font file by name in MacOS - application, they are based on QuickDraw Font Manager - and Apple Type Service framework of MacOS. - - FT_GetFile_From_Mac_Name() - FT_GetFile_From_Mac_ATS_Name() - - Working functions for each MacOS are summarized as - following. - - upto MacOS 6: - not tested (you have to obtain MPW 2.x) - - MacOS 7.x, 8.x, 9.x (without CarbonLib): - FT_GetFile_From_Mac_Name() - FT_New_Face_From_Resource() - FT_New_Face_From_FSSpec() - - MacOS 9.x (with CarbonLib): - FT_GetFile_From_Mac_Name() - FT_New_Face_From_Resource() - FT_New_Face_From_FSSpec() - FT_New_Face_From_FSRef() - - Mac OS X upto 10.4.x: - FT_GetFile_From_Mac_Name() deprecated - FT_New_Face_From_FSSpec() deprecated - FT_GetFile_From_Mac_ATS_Name() deprecated? - FT_New_Face_From_FSRef() - - A-2. Deprecated Functions - ------------------------- - - A-2-1. FileManager - ------------------ - - For convenience to write MacOS application, ftmac.c - provides functions to specify a file by FSSpec and FSRef, - because the file identification pathname had ever been - unrecommended method in MacOS programming. - - Toward to MacOS X 10.4 & 5, Carbon functions using FSSpec - datatype is noticed as deprecated, and recommended to - migrate to FSRef datatype. The big differences of FSRef - against FSSpec are explained in Apple TechNotes 2078. - - http://developer.apple.com/technotes/tn2002/tn2078.html - - - filename length: the max length of file - name of FSRef is 255 chars (it is limit of HFS+), - that of FSSpec is 31 chars (it is limit of HFS). - - - filename encoding: FSSpec is localized by - legacy encoding for each language system, - FSRef is Unicode enabled. - - A-2-2. FontManager - ------------------ - - Following functions receive QuickDraw fontname: - - FT_GetFile_From_Mac_Name() - - QuickDraw is deprecated and replaced by Quartz - since Mac OS X 10.4. They are still kept for - backward compatibility. By undefinition of - HAVE_QUICKDRAW in building, you can change these - functions to return FT_Err_Unimplemented always. - - Replacement functions are added for migration. - - FT_GetFile_From_Mac_ATS_Name() - - They are usable on Mac OS X only. On older systems, - these functions return FT_Err_Unimplemented always. - - The detailed incompatibilities and possibility - of FontManager emulation without QuickDraw is - explained in - - http://www.gyve.org/~mpsuzuki/ats_benchmark.html - - A-3. Framework Availabilities - ----------------------------- - - The framework of MacOS are often revised, especially - when new format of binary executable is introduced. - Following table is the minimum version of frameworks - to use functions used in FreeType2. The table is - extracted from MPW header files for assembly language. - - *** NOTE *** - The conditional definition of available data type - in MPW compiler is insufficient. You can compile - program using FSRef data type for older systems - (MacOS 7, 8) that don't know FSRef data type. - - - +-------------------+-----------------------------+ - CPU | mc680x0 | PowerPC | - +---------+---------+---------+---------+---------+ - Binary Executable Format | Classic | 68K-CFM | CFM | CFM | Mach-O | - +---------+---------+---------+---------+---------+ - Framework API | Toolbox | Toolbox | Toolbox | Carbon | Carbon | - +---------+---------+---------+---------+---------+ - - +---------+---------+---------+---------+---------+ - | ?(*) |Interface|Interface|CarbonLib|Mac OS X | - | |Lib |Lib | | | -* Files.h +---------+---------+---------+---------+---------+ -PBGetFCBInfoSync() | o | 7.1- | 7.1- | 1.0- | o | -FSMakeFSSpec() | o | 7.1- | 7.1- | 1.0- | o | -FSGetForkCBInfo() | o | (**) | 9.0- | 1.0- | o | -FSpMakeFSRef() | o | (**) | 9.0- | 1.0- | o | -FSGetCatalogInfo() | o | (**) | 9.0- | 1.0- | -10.3 | -FSPathMakeRef() | x | x | x | 1.1- | -10.3 | - +---------+---------+---------+---------+---------+ - - +---------+---------+---------+---------+---------+ - | ?(*) |Font |Font |CarbonLib|Mac OS X | - | |Manager |Manager | | | -* Fonts.h +---------+---------+---------+---------+---------+ -FMCreateFontFamilyIterator() | x | x | 9.0- | 1.0- | -10.3 | -FMDisposeFontFamilyIterator() | x | x | 9.0- | 1.0- | -10.3 | -FMGetNextFontFamily() | x | x | 9.0- | 1.0- | -10.3 | -FMGetFontFamilyName() | x | x | 9.0- | 1.0- | -10.3 | -FMCreateFontFamilyInstanceIterator() | x | x | 9.0- | 1.0- | -10.3 | -FMDisposeFontFamilyInstanceIterator() | x | x | 9.0- | 1.0- | -10.3 | -FMGetNextFontFamilyInstance() | x | x | 9.0- | 1.0- | -10.3 | - +---------+---------+---------+---------+---------+ - - +---------+---------+---------+---------+---------+ - | - | - | - |CarbonLib|Mac OS X | -* ATSFont.h (***) +---------+---------+---------+---------+---------+ -ATSFontFindFromName() | x | x | x | x | o | -ATSFontGetFileSpecification() | x | x | x | x | o | - +---------+---------+---------+---------+---------+ - - (*) - In the "Classic": the original binary executable - format, these framework functions are directly - transformed to MacOS system call.

To - support this I use the face_index argument of FT_(Open|New)_Face() - functions, and pretend the suitcase file is a collection. - - Warning: fbit and NFNT bitmap resources are not supported yet. In old - sfnt fonts, bitmap glyph data for each size is stored in each `NFNT' - resources instead of the `bdat' table in the sfnt resource. Therefore, - face->num_fixed_sizes is set to 0, because bitmap data in `NFNT' - resource is unavailable at present. - - The Mac FOND support works roughly like this: - - - Check whether the offered stream points to a Mac suitcase file. This - is done by checking the file type: it has to be 'FFIL' or 'tfil'. The - stream that gets passed to our init_face() routine is a stdio stream, - which isn't usable for us, since the FOND resources live in the - resource fork. So we just grab the stream->pathname field. - - - Read the FOND resource into memory, then check whether there is a - TrueType font and/or(!) a Type 1 font available. - - - If there is a Type 1 font available (as a separate `LWFN' file), read - its data into memory, massage it slightly so it becomes PFB data, wrap - it into a memory stream, load the Type 1 driver and delegate the rest - of the work to it by calling FT_Open_Face(). (XXX TODO: after this - has been done, the kerning data from the FOND resource should be - appended to the face: On the Mac there are usually no AFM files - available.

- FreeType 2 Project Files for VS.NET 2010 -

- -

This directory contains a project file for Visual C++, named -freetype.vcxproj, and Visual Studio, called freetype.sln. It -compiles the following libraries from the FreeType 2.4.11 sources:

- -
    - 
    -    freetype2411.lib     - release build; single threaded
-    freetype2411_D.lib   - debug build;   single threaded
-    freetype2411MT.lib   - release build; multi-threaded
-    freetype2411MT_D.lib - debug build;   multi-threaded
    -
- -

Be sure to extract the files with the Windows (CR+LF) line endings. ZIP -archives are already stored this way, so no further action is required. If -you use some .tar.*z archives, be sure to configure your extracting -tool to convert the line endings. For example, with WinZip, you should activate the TAR -file smart CR/LF Conversion option. Alternatively, you may consider -using the unix2dos or u2d utilities that are floating -around, which specifically deal with this particular problem. - -

Build directories are placed in the top-level objs -directory.

This directory contains project files for Visual C++, named -freetype.dsp, and Visual Studio, called freetype.sln. It -compiles the following libraries from the FreeType 2.4.11 sources:

- -
    - 
    -    freetype2411.lib     - release build; single threaded
-    freetype2411_D.lib   - debug build;   single threaded
-    freetype2411MT.lib   - release build; multi-threaded
-    freetype2411MT_D.lib - debug build;   multi-threaded
    -
- -

Be sure to extract the files with the Windows (CR+LF) line endings. ZIP -archives are already stored this way, so no further action is required. If -you use some .tar.*z archives, be sure to configure your extracting -tool to convert the line endings. For example, with WinZip, you should activate the TAR -file smart CR/LF Conversion option. Alternatively, you may consider -using the unix2dos or u2d utilities that are floating -around, which specifically deal with this particular problem. - -

Build directories are placed in the top-level objs -directory.

This directory contains project files for Visual C++, named -freetype.dsp, and Visual Studio, called freetype.sln for -the following targets: - -

    -
  • PPC/SP 2003 (Pocket PC 2003)
    • -
  • PPC/SP WM5 (Windows Mobile 5)
    • -
  • PPC/SP WM6 (Windows Mobile 6)
    • -
- -It compiles the following libraries from the FreeType 2.4.11 sources:

- -
    - 
    -    freetype2411.lib     - release build; single threaded
-    freetype2411_D.lib   - debug build;   single threaded
-    freetype2411MT.lib   - release build; multi-threaded
-    freetype2411MT_D.lib - debug build;   multi-threaded
    -
- -

Be sure to extract the files with the Windows (CR+LF) line endings. ZIP -archives are already stored this way, so no further action is required. If -you use some .tar.*z archives, be sure to configure your extracting -tool to convert the line endings. For example, with WinZip, you should activate the TAR -file smart CR/LF Conversion option. Alternatively, you may consider -using the unix2dos or u2d utilities that are floating -around, which specifically deal with this particular problem. - -

Build directories are placed in the top-level objs -directory.

Be sure to extract the files with the Windows (CR+LF) line endings. ZIP -archives are already stored this way, so no further action is required. If -you use some .tar.*z archives, be sure to configure your extracting -tool to convert the line endings. For example, with WinZip, you should activate the TAR -file smart CR/LF Conversion option. Alternatively, you may consider -using the unix2dos or u2d utilities that are floating -around, which specifically deal with this particular problem. - -

Build directories are placed in the top-level objs -directory.

- -It compiles the following libraries from the FreeType 2.4.11 sources:

- -
    - 
    -    freetype2411.lib     - release build; single threaded
-    freetype2411_D.lib   - debug build;   single threaded
-    freetype2411MT.lib   - release build; multi-threaded
-    freetype2411MT_D.lib - debug build;   multi-threaded

Be sure to extract the files with the Windows (CR+LF) line endings. ZIP -archives are already stored this way, so no further action is required. If -you use some .tar.*z archives, be sure to configure your extracting -tool to convert the line endings. For example, with WinZip, you should activate the TAR -file smart CR/LF Conversion option. Alternatively, you may consider -using the unix2dos or u2d utilities that are floating -around, which specifically deal with this particular problem. - -

Build directories are placed in the top-level objs -directory.

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.

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.

Their default values being - and , you - can do something like: - - custom/ - freetype/ - config/ - ftoption.h => custom options header - ftmodule.h => custom modules list - - include/ => normal FreeType 2 include - freetype/ - ... - - 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.

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 `ftoptions.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 will 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 will dump memory statistics, - including the list of leaked memory blocks 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. - - -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), but will not stop 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 will abort 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. For 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 used to name 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 trace_io - - The value of the FT_COMPONENT macro is an enumeration named - trace_XXXX where XXXX is one of the component names defined in the - internal file `freetype/internal/fttrace.h'. If you modify FreeType - source and insert new trace_XXXX macro, you must register it in - fttrace.h. If you insert or remove many trace macros, you can check - the undefined or the unused trace macro by src/tools/chktrcmp.py. - - Each such component is assigned a `debug level', ranging from 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 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. - - The second parameter to FT_TRACE must contain parentheses and - correspond 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', but without the `trace_' prefix. `levelX' is the - corresponding level to use at runtime. - - `any' is a special component name that will be 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 will be set to trace levels 5 and - 4, respectively. - - - FT2_DEBUG_MEMORY - - This environment variable, when defined, tells FreeType to use a - debugging memory manager that will track 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 will be - 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, then - 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, then - no allocation bounds are checked at runtime. - ------------------------------------------------------------------------- - -Copyright 2002, 2003, 2004, 2005, 2009 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.

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.

Required Tools - ----------------- - - For self-building the FreeType library on a Unix system, GNU Make - 3.80 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. - At present, using non-GNU cross compiler is not tested. 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 - that is executed during the building procedure. Non-GNU self - compilers are acceptable, but such a setup is not tested yet. - - - 2. Configuration - ---------------- - - 2.1. Building and target system - - To configure for cross-build, the options `--host=' and - `--build=' must be passed to configure. For example, if - your building 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, configuration with - `--prefix=/usr/local' installs binaries into the system wide - `/usr/local' directory which then can't be executed. This - causes confusion in configuration of all applications which 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 FreeType2 is used as a part of - the target system, the prefix to install should reflect the file - system structure of the target system. - - - 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.

It does _not_ support the build - of DLLs on Windows and OS/2.

Introduction -=============== - - A rasterizer is a library in charge of converting a vectorial - representation of a shape into a bitmap. The FreeType rasterizer - has been originally developed to render the glyphs found in - TrueType files, made up of segments and second-order Béziers. - Meanwhile it has been extended to render third-order Bézier curves - also. This document is an explanation of its design and - implementation. - - While these explanations start from the basics, a knowledge of - common rasterization techniques is assumed. - - -II. Rendering Technology -======================== - -1. Requirements ---------------- - - We assume that all scaling, rotating, hinting, etc., has been - already done. The glyph is thus described by a list of points in - the device space. - - - All point coordinates are in the 26.6 fixed float format. The - used orientation is: - - - ^ y - | reference orientation - | - *----> x - 0 - - - `26.6' means that 26 bits are used for the integer part of a - value and 6 bits are used for the fractional part. - Consequently, the `distance' between two neighbouring pixels is - 64 `units' (1 unit = 1/64th of a pixel). - - Note that, for the rasterizer, pixel centers are located at - integer coordinates. The TrueType bytecode interpreter, - however, assumes that the lower left edge of a pixel (which is - taken to be a square with a length of 1 unit) has integer - coordinates. - - - ^ y ^ y - | | - | (1,1) | (0.5,0.5) - +-----------+ +-----+-----+ - | | | | | - | | | | | - | | | o-----+-----> x - | | | (0,0) | - | | | | - o-----------+-----> x +-----------+ - (0,0) (-0.5,-0.5) - - TrueType bytecode interpreter FreeType rasterizer - - - A pixel line in the target bitmap is called a `scanline'. - - - A glyph is usually made of several contours, also called - `outlines'. A contour is simply a closed curve that delimits an - outer or inner region of the glyph. It is described by a series - of successive points of the points table. - - Each point of the glyph has an associated flag that indicates - whether it is `on' or `off' the curve. Two successive `on' - points indicate a line segment joining the two points. - - One `off' point amidst two `on' points indicates a second-degree - (conic) Bézier parametric arc, defined by these three points - (the `off' point being the control point, and the `on' ones the - start and end points). Similarly, a third-degree (cubic) Bézier - curve is described by four points (two `off' control points - between two `on' points). - - Finally, for second-order curves only, two successive `off' - points forces the rasterizer to create, during rendering, an - `on' point amidst them, at their exact middle. This greatly - facilitates the definition of successive Bézier arcs. - - The parametric form of a second-order Bézier curve is: - - P(t) = (1-t)^2*P1 + 2*t*(1-t)*P2 + t^2*P3 - - (P1 and P3 are the end points, P2 the control point.) - - The parametric form of a third-order Bézier curve is: - - P(t) = (1-t)^3*P1 + 3*t*(1-t)^2*P2 + 3*t^2*(1-t)*P3 + t^3*P4 - - (P1 and P4 are the end points, P2 and P3 the control points.) - - For both formulae, t is a real number in the range [0..1]. - - Note that the rasterizer does not use these formulae directly. - They exhibit, however, one very useful property of Bézier arcs: - Each point of the curve is a weighted average of the control - points. - - As all weights are positive and always sum up to 1, whatever the - value of t, each arc point lies within the triangle (polygon) - defined by the arc's three (four) control points. - - In the following, only second-order curves are discussed since - rasterization of third-order curves is completely identical. - - Here some samples for second-order curves. - - - * # on curve - * off curve - __---__ - #-__ _-- -_ - --__ _- - - --__ # \ - --__ # - -# - Two `on' points - Two `on' points and one `off' point - between them - - * - # __ Two `on' points with two `off' - \ - - points between them.

Profiles and Spans ---------------------- - - The following is a basic explanation of the _kind_ of computations - made by the rasterizer to build a bitmap from a vector - representation. Note that the actual implementation is slightly - different, due to performance tuning and other factors. - - However, the following ideas remain in the same category, and are - more convenient to understand. - - - a. Sweeping the Shape - - The best way to fill a shape is to decompose it into a number of - simple horizontal segments, then turn them on in the target - bitmap. These segments are called `spans'. - - __---__ - _-- -_ - _- - - - \ - / \ - / \ - | \ - - __---__ Example: filling a shape - _----------_ with spans. - _-------------- - ----------------\ - /-----------------\ This is typically done from the top - / \ to the bottom of the shape, in a - | | \ movement called a `sweep'. - V - - __---__ - _----------_ - _-------------- - ----------------\ - /-----------------\ - /-------------------\ - |---------------------\ - - - In order to draw a span, the rasterizer must compute its - coordinates, which are simply the x coordinates of the shape's - contours, taken on the y scanlines. - - - /---/ |---| Note that there are usually - /---/ |---| several spans per scanline. - | /---/ |---| - | /---/_______|---| When rendering this shape to the - V /----------------| current scanline y, we must - /-----------------| compute the x values of the - a /----| |---| points a, b, c, and d. - - - - * * - - - - * * - - y - - / / b c| |d - - - /---/ |---| - /---/ |---| And then turn on the spans a-b - /---/ |---| and c-d. - /---/_______|---| - /----------------| - /-----------------| - a /----| |---| - - - - ####### - - - - ##### - - y - - / / b c| |d - - - b. Decomposing Outlines into Profiles - - For each scanline during the sweep, we need the following - information: - - o The number of spans on the current scanline, given by the - number of shape points intersecting the scanline (these are - the points a, b, c, and d in the above example). - - o The x coordinates of these points. - - x coordinates are computed before the sweep, in a phase called - `decomposition' which converts the glyph into *profiles*. - - Put it simply, a `profile' is a contour's portion that can only - be either ascending or descending, i.e., it is monotonic in the - vertical direction (we also say y-monotonic). There is no such - thing as a horizontal profile, as we shall see. - - Here are a few examples: - - - this square - 1 2 - ---->---- is made of two - | | | | - | | profiles | | - ^ v ^ + v - | | | | - | | | | - ----<---- - - up down - - - this triangle - - P2 1 2 - - |\ is made of two | \ - ^ | \ \ | \ - | | \ \ profiles | \ | - | | \ v ^ | \ | - | \ | | + \ v - | \ | | \ - P1 ---___ \ ---___ \ - ---_\ ---_ \ - <--__ P3 up down - - - - A more general contour can be made of more than two profiles: - - __ ^ - / | / ___ / | - / | / | / | / | - | | / / => | v / / - | | | | | | ^ | - ^ | |___| | | ^ + | + | + v - | | | v | | - | | | up | - |___________| | down | - - <-- up down - - - Successive profiles are always joined by horizontal segments - that are not part of the profiles themselves. - - For the rasterizer, a profile is simply an *array* that - associates one horizontal *pixel* coordinate to each bitmap - *scanline* crossed by the contour's section containing the - profile. Note that profiles are *oriented* up or down along the - glyph's original flow orientation. - - In other graphics libraries, profiles are also called `edges' or - `edgelists'. - - - c. The Render Pool - - FreeType has been designed to be able to run well on _very_ - light systems, including embedded systems with very few memory. - - A render pool will be allocated once; the rasterizer uses this - pool for all its needs by managing this memory directly in it. - The algorithms that are used for profile computation make it - possible to use the pool as a simple growing heap. This means - that this memory management is actually quite easy and faster - than any kind of malloc()/free() combination. - - Moreover, we'll see later that the rasterizer is able, when - dealing with profiles too large and numerous to lie all at once - in the render pool, to immediately decompose recursively the - rendering process into independent sub-tasks, each taking less - memory to be performed (see `sub-banding' below). - - The render pool doesn't need to be large. A 4KByte pool is - enough for nearly all renditions, though nearly 100% slower than - a more comfortable 16KByte or 32KByte pool (that was tested with - complex glyphs at sizes over 500 pixels). - - - d. Computing Profiles Extents - - Remember that a profile is an array, associating a _scanline_ to - the x pixel coordinate of its intersection with a contour. - - Though it's not exactly how the FreeType rasterizer works, it is - convenient to think that we need a profile's height before - allocating it in the pool and computing its coordinates. - - The profile's height is the number of scanlines crossed by the - y-monotonic section of a contour. We thus need to compute these - sections from the vectorial description. In order to do that, - we are obliged to compute all (local and global) y extrema of - the glyph (minima and maxima). - - - P2 For instance, this triangle has only - two y-extrema, which are simply - |\ - | \ P2.y as a vertical maximum - | \ P3.y as a vertical minimum - | \ - | \ P1.y is not a vertical extremum (though - | \ it is a horizontal minimum, which we - P1 ---___ \ don't need). - ---_\ - P3 - - - Note that the extrema are expressed in pixel units, not in - scanlines. The triangle's height is certainly (P3.y-P2.y+1) - pixel units, but its profiles' heights are computed in - scanlines. The exact conversion is simple: - - - min scanline = FLOOR ( min y ) - - max scanline = CEILING( max y ) - - A problem arises with Bézier Arcs. While a segment is always - necessarily y-monotonic (i.e., flat, ascending, or descending), - which makes extrema computations easy, the ascent of an arc can - vary between its control points. - - - P2 - * - # on curve - * off curve - __-x--_ - _-- -_ - P1 _- - A non y-monotonic Bézier arc. - # \ - - The arc goes from P1 to P3. - \ - \ P3 - # - - - We first need to be able to easily detect non-monotonic arcs, - according to their control points. I will state here, without - proof, that the monotony condition can be expressed as: - - P1.y <= P2.y <= P3.y for an ever-ascending arc - - P1.y >= P2.y >= P3.y for an ever-descending arc - - with the special case of - - P1.y = P2.y = P3.y where the arc is said to be `flat'. - - As you can see, these conditions can be very easily tested. - They are, however, extremely important, as any arc that does not - satisfy them necessarily contains an extremum. - - Note also that a monotonic arc can contain an extremum too, - which is then one of its `on' points: - - - P1 P2 - #---__ * P1P2P3 is ever-descending, but P1 - -_ is an y-extremum. - - - ---_ \ - -> \ - \ P3 - # - - - Let's go back to our previous example: - - - P2 - * - # on curve - * off curve - __-x--_ - _-- -_ - P1 _- - A non-y-monotonic Bézier arc. - # \ - - Here we have - \ P2.y >= P1.y && - \ P3 P2.y >= P3.y (!) - # - - - We need to compute the vertical maximum of this arc to be able - to compute a profile's height (the point marked by an `x'). The - arc's equation indicates that a direct computation is possible, - but we rely on a different technique, which use will become - apparent soon. - - Bézier arcs have the special property of being very easily - decomposed into two sub-arcs, which are themselves Bézier arcs. - Moreover, it is easy to prove that there is at most one vertical - extremum on each Bézier arc (for second-degree curves; similar - conditions can be found for third-order arcs). - - For instance, the following arc P1P2P3 can be decomposed into - two sub-arcs Q1Q2Q3 and R1R2R3: - - - P2 - * - # on curve - * off curve - - - original Bézier arc P1P2P3. - __---__ - _-- --_ - _- -_ - - - - / \ - / \ - # # - P1 P3 - - - - P2 - * - - - - Q3 Decomposed into two subarcs - Q2 R2 Q1Q2Q3 and R1R2R3 - * __-#-__ * - _-- --_ - _- R1 -_ Q1 = P1 R3 = P3 - - - Q2 = (P1+P2)/2 R2 = (P2+P3)/2 - / \ - / \ Q3 = R1 = (Q2+R2)/2 - # # - Q1 R3 Note that Q2, R2, and Q3=R1 - are on a single line which is - tangent to the curve. - - - We have then decomposed a non-y-monotonic Bézier curve into two - smaller sub-arcs. Note that in the above drawing, both sub-arcs - are monotonic, and that the extremum is then Q3=R1. However, in - a more general case, only one sub-arc is guaranteed to be - monotonic. Getting back to our former example: - - - Q2 - * - - __-x--_ R1 - _-- #_ - Q1 _- Q3 - R2 - # \ * - - - \ - \ R3 - # - - - Here, we see that, though Q1Q2Q3 is still non-monotonic, R1R2R3 - is ever descending: We thus know that it doesn't contain the - extremum. We can then re-subdivide Q1Q2Q3 into two sub-arcs and - go on recursively, stopping when we encounter two monotonic - subarcs, or when the subarcs become simply too small. - - We will finally find the vertical extremum. Note that the - iterative process of finding an extremum is called `flattening'. - - - e. Computing Profiles Coordinates - - Once we have the height of each profile, we are able to allocate - it in the render pool. The next task is to compute coordinates - for each scanline. - - In the case of segments, the computation is straightforward, - using the Euclidean algorithm (also known as Bresenham). - However, for Bézier arcs, the job is a little more complicated. - - We assume that all Béziers that are part of a profile are the - result of flattening the curve, which means that they are all - y-monotonic (ascending or descending, and never flat). We now - have to compute the intersections of arcs with the profile's - scanlines. One way is to use a similar scheme to flattening - called `stepping'. - - - Consider this arc, going from P1 to - --------------------- P3. Suppose that we need to - compute its intersections with the - drawn scanlines. As already - --------------------- mentioned this can be done - directly, but the involved - * P2 _---# P3 algorithm is far too slow. - ------------- _-- -- - _- - _/ Instead, it is still possible to - ---------/----------- use the decomposition property in - / the same recursive way, i.e., - | subdivide the arc into subarcs - ------|-------------- until these get too small to cross - | more than one scanline! - | - -----|--------------- This is very easily done using a - | rasterizer-managed stack of - | subarcs. - # P1 - - - f. Sweeping and Sorting the Spans - - Once all our profiles have been computed, we begin the sweep to - build (and fill) the spans. - - As both the TrueType and Type 1 specifications use the winding - fill rule (but with opposite directions), we place, on each - scanline, the present profiles in two separate lists. - - One list, called the `left' one, only contains ascending - profiles, while the other `right' list contains the descending - profiles. - - As each glyph is made of closed curves, a simple geometric - property ensures that the two lists contain the same number of - elements. - - Creating spans is thus straightforward: - - 1. We sort each list in increasing horizontal order. - - 2. We pair each value of the left list with its corresponding - value in the right list. - - - / / | | For example, we have here - / / | | four profiles. Two of - >/ / | | | them are ascending (1 & - 1// / ^ | | | 2 3), while the two others - // // 3| | | v are descending (2 & 4). - / //4 | | | On the given scanline, - a / /< | | the left list is (1,3), - - - - *-----* - - - - *---* - - y - and the right one is - / / b c| |d (4,2) (sorted). - - There are then two spans, joining - 1 to 4 (i.e. a-b) and 3 to 2 - (i.e. c-d)! - - - Sorting doesn't necessarily take much time, as in 99 cases out - of 100, the lists' order is kept from one scanline to the next. - We can thus implement it with two simple singly-linked lists, - sorted by a classic bubble-sort, which takes a minimum amount of - time when the lists are already sorted. - - A previous version of the rasterizer used more elaborate - structures, like arrays to perform `faster' sorting. It turned - out that this old scheme is not faster than the one described - above. - - Once the spans have been `created', we can simply draw them in - the target bitmap. - ------------------------------------------------------------------------- - -Copyright 2003, 2007 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.

While FreeType's auto-hinter doesn't expose API functions by itself, it is possible to control its behaviour with FT_Property_Set and FT_Property_Get. The following lists the available properties together with the necessary macros and structures.

-

Note that the auto-hinter's module name is ‘autofitter’ for historical reasons.

-

-
-

glyph-to-script-map

-
-

The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.

-

OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called ‘features’. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.

-

The mapping between glyph indices and scripts (in the auto-hinter sense, see the FT_AUTOHINTER_SCRIPT_XXX values) is stored as an array with ‘num_glyphs’ elements, as found in the font's FT_Face structure. The ‘glyph-to-script-map’ property returns a pointer to this array which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.

-

The following example code demonstrates how to access it (omitting the error handling).

FT_Prop_GlyphToScriptMap

-
-Defined in FT_AUTOHINTER_H (freetype/ftautoh.h). -

-
-
-   typedef struct  FT_Prop_GlyphToScriptMap_

fallback-script

-
-

If no auto-hinter script module can be assigned to a glyph, a fallback script gets assigned to it (see also the glyph-to-script-map property). By default, this is FT_AUTOHINTER_SCRIPT_CJK. Using the ‘fallback-script’ property, this fallback value can be changed.

-
-  FT_Library  library;
-  FT_UInt     fallback_script = FT_AUTOHINTER_SCRIPT_NONE;
-
-
-  FT_Init_FreeType( &library );
-
-  FT_Property_Set( library, "autofitter",
-                            "fallback-script", &fallback_script );
-
-

-
note
-

This property can be used with FT_Property_Get also.

-

It's important to use the right timing for changing this value: The creation of the glyph-to-script map which eventually uses the fallback script value gets triggered either by setting or reading a face-specific property like glyph-to-script-map, or by auto-hinting any glyph from that face. In particular, if you have already created an FT_Face structure but not loaded any glyph (using the auto-hinter), a change of the fallback glyph will affect this face.

increase-x-height

-
-

For ppem values in the range 6 <= ppem <= ‘increase-x-height’, round up the font's x height much more often than normally. If the value is set to 0, which is the default, this feature is switched off. Use this property to improve the legibility of small font sizes if necessary.

-
-  FT_Library               library;
-  FT_Face                  face;
-  FT_Prop_IncreaseXHeight  prop;
-
-
-  FT_Init_FreeType( &library );
-  FT_New_Face( library, "foo.ttf", 0, &face );
-  FT_Set_Char_Size( face, 10 * 64, 0, 72, 0 );

-  FT_Property_Set( library, "autofitter",
-                            "increase-x-height", &prop );
-
-

-
note
-

This property can be used with FT_Property_Get also.

-

Set this value right after calling FT_Set_Char_Size, but before loading any glyph (using the auto-hinter).

note
-

The bounding box is specified with the coordinates of the lower left and the upper right corner. In PostScript, those values are often called (llx,lly) and (urx,ury), respectively.

-

If ‘yMin’ is negative, this value gives the glyph's descender. Otherwise, the glyph doesn't descend below the baseline. Similarly, if ‘ymax’ is positive, this value gives the glyph's ascender.

-

‘xMin’ gives the horizontal distance from the glyph's origin to the left edge of the glyph's bounding box. If ‘xMin’ is negative, the glyph extends to the left of the origin.

-
FT_PIXEL_MODE_GRAY -

An 8-bit bitmap, generally used to represent anti-aliased glyph images. Each pixel is stored in one byte. Note that the number of ‘gray’ levels is stored in the ‘num_grays’ field of the FT_Bitmap structure (it generally is 256).

-
FT_PIXEL_MODE_GRAY2 -

FT_PIXEL_MODE_GRAY4 -

A 4-bit per pixel bitmap, representing embedded anti-aliased bitmaps in font files according to the OpenType specification. We haven't found a single font using this format, however.

-
FT_PIXEL_MODE_LCD -

An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on LCD displays; the bitmap is three times wider than the original glyph image. See also FT_RENDER_MODE_LCD.

-
FT_PIXEL_MODE_LCD_V -

An 8-bit bitmap, representing RGB or BGR decimated glyph images used for display on rotated LCD displays; the bitmap is three times taller than the original glyph image. See also FT_RENDER_MODE_LCD_V.

-

-
-

THIS TYPE IS DEPRECATED. DO NOT USE IT!

-

An enumeration type to describe the format of a bitmap palette, used with ft_pixel_mode_pal4 and ft_pixel_mode_pal8.

-

-
values
-

- - - -
ft_palette_mode_rgb -

The palette is an array of 3-byte RGB records.

-
ft_palette_mode_rgba -

The palette is an array of 4-byte RGBA records.

-
-
-
note
-

As ft_pixel_mode_pal2, pal4 and pal8 are currently unused by FreeType, these types are not handled by the library itself.

FT_Bitmap

-
-Defined in FT_IMAGE_H (freetype/ftimage.h). -

-
-
-  typedef struct  FT_Bitmap_
-  {
-    int             rows;
-    int             width;
-    int             pitch;
-    unsigned char*  buffer;
-    short           num_grays;
-    char            pixel_mode;
-    char            palette_mode;
-    void*           palette;
-
-  } FT_Bitmap;
-
-

-
-

A structure used to describe a bitmap or pixmap to the raster. Note that we now manage pixmaps of various depths through the ‘pixel_mode’ field.

-

-
fields
-

- - - - - - - - - -
rows -

The number of bitmap rows.

-
width -

The number of pixels in bitmap row.

-
pitch -

The pitch's absolute value is the number of bytes taken by one bitmap row, including padding. However, the pitch is positive when the bitmap has a ‘down’ flow, and negative when it has an ‘up’ flow. In all cases, the pitch is an offset to add to a bitmap pointer in order to go down one row.

-

Note that ‘padding’ means the alignment of a bitmap to a byte border, and FreeType functions normally align to the smallest possible integer value.

-

For the B/W rasterizer, ‘pitch’ is always an even number.

-

To change the pitch of a bitmap (say, to make it a multiple of 4), use FT_Bitmap_Convert. Alternatively, you might use callback functions to directly render to the application's surface; see the file ‘example2.cpp’ in the tutorial for a demonstration.

-
buffer -

A typeless pointer to the bitmap buffer. This value should be aligned on 32-bit boundaries in most cases.

-
num_grays -

This field is only used with FT_PIXEL_MODE_GRAY; it gives the number of gray levels used in the bitmap.

-
pixel_mode -

The pixel mode, i.e., how pixel bits are stored. See FT_Pixel_Mode for possible values.

-
palette_mode -

This field is intended for paletted pixel modes; it indicates how the palette is stored. Not used currently.

-
palette -

A typeless pointer to the bitmap palette; this field is intended for paletted pixel modes. Not used currently.

-
-
-
note
-

For now, the only pixel modes supported by FreeType are mono and grays. However, drivers might be added in the future to support more ‘colorful’ options.

FT_IMAGE_TAG

-
-Defined in FT_IMAGE_H (freetype/ftimage.h). -

-
-
-#ifndef FT_IMAGE_TAG
-#define FT_IMAGE_TAG( value, _x1, _x2, _x3, _x4 )  \
-          value = ( ( (unsigned long)_x1 << 24 ) | \
-                    ( (unsigned long)_x2 << 16 ) | \
-                    ( (unsigned long)_x3 << 8  ) | \
-                      (unsigned long)_x4         )
-#endif /* FT_IMAGE_TAG */
-
-

-
-

This macro converts four-letter tags to an unsigned long type.

-

-
note
-

Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this:

-
-  #define FT_IMAGE_TAG( value, _x1, _x2, _x3, _x4 )  value         
-
-

to get a simple enumeration without assigning special numbers.

FT_Glyph_Format

-
-Defined in FT_IMAGE_H (freetype/ftimage.h). -

-
-
-  typedef enum  FT_Glyph_Format_
-  {
-    FT_IMAGE_TAG( FT_GLYPH_FORMAT_NONE, 0, 0, 0, 0 ),
-
-    FT_IMAGE_TAG( FT_GLYPH_FORMAT_COMPOSITE, 'c', 'o', 'm', 'p' ),
-    FT_IMAGE_TAG( FT_GLYPH_FORMAT_BITMAP,    'b', 'i', 't', 's' ),
-    FT_IMAGE_TAG( FT_GLYPH_FORMAT_OUTLINE,   'o', 'u', 't', 'l' ),
-    FT_IMAGE_TAG( FT_GLYPH_FORMAT_PLOTTER,   'p', 'l', 'o', 't' )
-
-  } FT_Glyph_Format;
-
-

-
-

An enumeration type used to describe the format of a given glyph image. Note that this version of FreeType only supports two image formats, even though future font drivers will be able to register their own format.

-

-
values
-

- - - - - - - - - -
FT_GLYPH_FORMAT_NONE -

The value 0 is reserved.

-
FT_GLYPH_FORMAT_COMPOSITE
-

The glyph image is a composite of several other images. This format is only used with FT_LOAD_NO_RECURSE, and is used to report compound glyphs (like accented characters).

-
FT_GLYPH_FORMAT_BITMAP -

The glyph image is a bitmap, and can be described as an FT_Bitmap. You generally need to access the ‘bitmap’ field of the FT_GlyphSlotRec structure to read it.

-
FT_GLYPH_FORMAT_OUTLINE
-

The glyph image is a vectorial outline made of line segments and Bézier arcs; it can be described as an FT_Outline; you generally want to access the ‘outline’ field of the FT_GlyphSlotRec structure to read it.

-
FT_GLYPH_FORMAT_PLOTTER
-

The glyph image is a vectorial path with no inside and outside contours. Some Type 1 fonts, like those in the Hershey family, contain glyphs in this format. These are described as FT_Outline, but FreeType isn't currently capable of rendering them correctly.

-
-
-  typedef void  (*FT_Generic_Finalizer)(void*  object);
-
-

-
-

Describe a function used to destroy the ‘client’ data of any FreeType object. See the description of the FT_Generic type for details of usage.

FT_Generic

-
-Defined in FT_TYPES_H (freetype/fttypes.h). -

-
-
-  typedef struct  FT_Generic_
-  {
-    void*                 data;
-    FT_Generic_Finalizer  finalizer;
-
-  } FT_Generic;
-
-

-
-

Client applications often need to associate their own data to a variety of FreeType core objects. For example, a text layout API might want to associate a glyph cache to a given size object.

-

Some FreeType object contains a ‘generic’ field, of type FT_Generic, which usage is left to client applications and font servers.

-

It can be used to store a pointer to client-specific data, as well as the address of a ‘finalizer’ function, which will be called by FreeType when the object is destroyed (for example, the previous client example would put the address of the glyph cache destructor in the ‘finalizer’ field).

-

-
fields
-

- - - -
data -

A typeless pointer to any client-specified data. This field is completely ignored by the FreeType library.

-
finalizer -

A pointer to a ‘generic finalizer’ function, which will be called when the object is destroyed. If this field is set to NULL, no code will be called.

FreeType error code. 0 means success.

-
-
note
-

This function works with BDF and PCF fonts. It returns an error otherwise. It also returns an error if the property is not in the font.

-

A ‘property’ is a either key-value pair within the STARTPROPERTIES ... ENDPROPERTIES block of a BDF font or a key-value pair from the ‘info->props’ array within a ‘FontRec’ structure of a PCF font.

-

Integer properties are always stored as ‘signed’ within PCF fonts; consequently, BDF_PROPERTY_TYPE_CARDINAL is a possible return value for BDF fonts only.

-

In case of error, ‘aproperty->type’ is always set to BDF_PROPERTY_TYPE_NONE.

-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

The source stream must be opened before calling this function.

-

Calling the internal function ‘FT_Stream_Close’ on the new stream will not call ‘FT_Stream_Close’ on the source stream. None of the stream objects will be released to the heap.

-

The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.

-

In certain builds of the library, bzip2 compression recognition is automatically handled when calling FT_New_Face or FT_Open_Face. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a bzip2 compressed stream from it and re-open the face with it.

-

This function may return ‘FT_Err_Unimplemented_Feature’ if your build of FreeType was not compiled with bzip2 support.

-

This section describes the FreeType 2 cache sub-system, which is used to limit the number of concurrently opened FT_Face and FT_Size objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.

-

Note that all types and functions begin with the ‘FTC_’ prefix.

-

The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:

-

First, available or installed font faces are uniquely identified by FTC_FaceID values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.

-

Second, the cache calls, only when needed, a client-provided function to convert an FTC_FaceID into a new FT_Face object. The latter is then completely managed by the cache, including its termination through FT_Done_Face. To monitor termination of face objects, the finalizer callback in the ‘generic’ field of the FT_Face object can be used, which might also be used to store the FTC_FaceID of the face.

-

Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call FT_New_Face. However, more complex schemes are also possible.

-

Note that for the cache to work correctly, the face ID values must be persistent, which means that the contents they point to should not change at runtime, or that their value should not become invalid.

-

If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call FTC_Manager_RemoveFaceID as soon as possible, to let the cache get rid of any references to the old FTC_FaceID it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.

-

To use the cache, start with calling FTC_Manager_New to create a new FTC_Manager object, which models a single cache instance. You can then look up FT_Face and FT_Size objects with FTC_Manager_LookupFace and FTC_Manager_LookupSize, respectively.

-

If you want to use the charmap caching, call FTC_CMapCache_New, then later use FTC_CMapCache_Lookup to perform the equivalent of FT_Get_Char_Index, only much faster.

-

If you want to use the FT_Glyph caching, call FTC_ImageCache, then later use FTC_ImageCache_Lookup to retrieve the corresponding FT_Glyph objects from the cache.

-

If you need lots of small bitmaps, it is much more memory efficient to call FTC_SBitCache_New followed by FTC_SBitCache_Lookup. This returns FTC_SBitRec structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).

-

We hope to also provide a kerning cache in the near future.

-

-

FTC_Manager

-
-Defined in FT_CACHE_H (freetype/ftcache.h). -

-
-
-  typedef struct FTC_ManagerRec_*  FTC_Manager;
-
-

-
-

This object corresponds to one instance of the cache-subsystem. It is used to cache one or more FT_Face objects, along with corresponding FT_Size objects.

-

The manager intentionally limits the total number of opened FT_Face and FT_Size objects to control memory usage. See the ‘max_faces’ and ‘max_sizes’ parameters of FTC_Manager_New.

-

The manager is also used to cache ‘nodes’ of various types while limiting their total memory usage.

-

All limitations are enforced by keeping lists of managed objects in most-recently-used order, and flushing old nodes to make room for new ones.

FTC_FaceID

-
-Defined in FT_CACHE_H (freetype/ftcache.h). -

-
-
-  typedef FT_Pointer  FTC_FaceID;
-
-

-
-

An opaque pointer type that is used to identity face objects. The contents of such objects is application-dependent.

-

These pointers are typically used to point to a user-defined structure containing a font file path, and face index.

-

-
note
-

Never use NULL as a valid FTC_FaceID.

-

Face IDs are passed by the client to the cache manager, which calls, when needed, the FTC_Face_Requester to translate them into new FT_Face objects.

-

If the content of a given face ID changes at runtime, or if the value becomes invalid (e.g., when uninstalling a font), you should immediately call FTC_Manager_RemoveFaceID before any other cache function.

-

Failure to do so will result in incorrect behaviour or even memory leaks and crashes.

FTC_Face_Requester

-
-Defined in FT_CACHE_H (freetype/ftcache.h). -

-
-
-  typedef FT_Error
-  (*FTC_Face_Requester)( FTC_FaceID  face_id,
-                         FT_Library  library,
-                         FT_Pointer  request_data,
-                         FT_Face*    aface );
-
-

-
-

A callback function provided by client applications. It is used by the cache manager to translate a given FTC_FaceID into a new valid FT_Face object, on demand.

-

-
input
-

- - - - -
face_id -

The face ID to resolve.

-
library -

A handle to a FreeType library object.

-
req_data -

Application-provided request data (see note below).

-
-
-
output
-

- - -
aface -

A new FT_Face handle.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

The third parameter ‘req_data’ is the same as the one passed by the client when FTC_Manager_New is called.

-

The face requester should not perform funny things on the returned face object, like creating a new FT_Size for it, or setting a transformation through FT_Set_Transform!

FTC_Node

-
-Defined in FT_CACHE_H (freetype/ftcache.h). -

-
-
-  typedef struct FTC_NodeRec_*  FTC_Node;
-
-

-
-

An opaque handle to a cache node object. Each cache node is reference-counted. A node with a count of 0 might be flushed out of a full cache whenever a lookup request is performed.

-

If you look up nodes, you have the ability to ‘acquire’ them, i.e., to increment their reference count. This will prevent the node from being flushed out of the cache until you explicitly ‘release’ it (see FTC_Node_Unref).

-

- - - -
manager -

A handle to the cache manager.

face_id -

The ID of the face object.

aface -

A handle to the face object.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

The returned FT_Face object is always owned by the manager. You should never try to discard it yourself.

-

The FT_Face object doesn't necessarily have a current size object (i.e., face->size can be 0). If you need a specific ‘font size’, use FTC_Manager_LookupSize instead.

-

Never change the face's transformation matrix (i.e., never call the FT_Set_Transform function) on a returned face! If you need to transform glyphs, do it yourself after glyph loading.

-

When you perform a lookup, out-of-memory errors are detected within the lookup and force incremental flushes of the cache until enough memory is released for the lookup to succeed.

-

If a lookup fails with ‘FT_Err_Out_Of_Memory’ the cache has already been completely flushed, and still no memory was available for the operation.

-
-
note
-

The returned glyph is owned and managed by the glyph image cache. Never try to transform or discard it manually! You can however create a copy with FT_Glyph_Copy and modify the new one.

-

If ‘anode’ is not NULL, it receives the address of the cache node containing the glyph image, after increasing its reference count. This ensures that the node (as well as the FT_Glyph) will always be kept in the cache until you call FTC_Node_Unref to ‘release’ it.

-

If ‘anode’ is NULL, the cache node is left unchanged, which means that the FT_Glyph could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent!

The corresponding FT_Glyph object. 0 in case of failure.

-
anode -

Used to return the address of of the corresponding cache node after incrementing its reference count (see note below).

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

The returned glyph is owned and managed by the glyph image cache. Never try to transform or discard it manually! You can however create a copy with FT_Glyph_Copy and modify the new one.

-

If ‘anode’ is not NULL, it receives the address of the cache node containing the glyph image, after increasing its reference count. This ensures that the node (as well as the FT_Glyph) will always be kept in the cache until you call FTC_Node_Unref to ‘release’ it.

-

If ‘anode’ is NULL, the cache node is left unchanged, which means that the FT_Glyph could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent!

-

Calls to FT_Set_Char_Size and friends have no effect on cached glyphs; you should always use the FreeType cache API instead.

This section contains various functions used to perform computations on 16.16 fixed-float numbers or 2d vectors.

-

-
-

FT_MulDiv

-
-Defined in FT_FREETYPE_H (freetype/freetype.h). -

-
-
-  FT_EXPORT( FT_Long )
-  FT_MulDiv( FT_Long  a,
-             FT_Long  b,
-             FT_Long  c );
-
-

-
-

A very simple function used to perform the computation ‘(a*b)/c’ with maximum accuracy (it uses a 64-bit intermediate integer whenever necessary).

-

This function isn't necessarily as fast as some processor specific operations, but is at least completely portable.

-

-
input
-

- - - - -
a -

The first multiplier.

-
b -

The second multiplier.

-
c -

The divisor.

-
-
-
return
-

The result of ‘(a*b)/c’. This function never traps when trying to divide by zero; it simply returns ‘MaxInt’ or ‘MinInt’ depending on the signs of ‘a’ and ‘b’.

-

-

FT_MulFix

-
-Defined in FT_FREETYPE_H (freetype/freetype.h). -

-
-
-  FT_EXPORT( FT_Long )
-  FT_MulFix( FT_Long  a,
-             FT_Long  b );
-
-

-
-

A very simple function used to perform the computation ‘(a*b)/0x10000’ with maximum accuracy. Most of the time this is used to multiply a given value by a 16.16 fixed float factor.

-

-
input
-

- - - -
a -

The first multiplier.

-
b -

The second multiplier. Use a 16.16 factor here whenever possible (see note below).

-
-
-
return
-

The result of ‘(a*b)/0x10000’.

-
-
note
-

This function has been optimized for the case where the absolute value of ‘a’ is less than 2048, and ‘b’ is a 16.16 scaling factor. As this happens mainly when scaling from notional units to fractional pixels in FreeType, it resulted in noticeable speed improvements between versions 2.x and 1.x.

-

As a conclusion, always try to place a 16.16 factor as the second argument of this function; this can make a great difference.

FT_DivFix

-
-Defined in FT_FREETYPE_H (freetype/freetype.h). -

-
-
-  FT_EXPORT( FT_Long )
-  FT_DivFix( FT_Long  a,
-             FT_Long  b );
-
-

-
-

A very simple function used to perform the computation ‘(a*0x10000)/b’ with maximum accuracy. Most of the time, this is used to divide a given value by a 16.16 fixed float factor.

-

-
input
-

- - - -
a -

The first multiplier.

-
b -

The second multiplier. Use a 16.16 factor here whenever possible (see note below).

-
-
-
return
-

The result of ‘(a*0x10000)/b’.

-
-
note
-

The optimization for FT_DivFix() is simple: If (a << 16) fits in 32 bits, then the division is computed directly. Otherwise, we use a specialized version of FT_MulDiv.

FT_Get_X11_Font_Format


- -
-

The single function in this section can be used to get the font format. Note that this information is not needed normally; however, there are special cases (like in PDF devices) where it is important to differentiate, in spite of FreeType's uniform API.

-

This function is in the X11/xf86 namespace for historical reasons and in no way depends on that windowing system.

-

FT_GASP_XXXFT_Get_Gasp


- -
-

The function FT_Get_Gasp can be used to query a TrueType or OpenType font for specific entries in its ‘gasp’ table, if any. This is mainly useful when implementing native TrueType hinting with the bytecode interpreter to duplicate the Windows text rendering results.

values
-

- - - - - - - - -
FT_GASP_NO_TABLE -

This special value means that there is no GASP table in this face. It is up to the client to decide what to do.

-
FT_GASP_DO_GRIDFIT -

Grid-fitting and hinting should be performed at the specified ppem. This really means TrueType bytecode interpretation. If this bit is not set, no hinting gets applied.

-
FT_GASP_DO_GRAY -

Anti-aliased rendering should be performed at the specified ppem. If not set, do monochrome rendering.

-
FT_GASP_SYMMETRIC_SMOOTHING
-

If set, smoothing along multiple axes must be used with ClearType.

-
FT_GASP_SYMMETRIC_GRIDFIT
-

Grid-fitting must be used with ClearType's symmetric smoothing.

-
-
-
note
-

The bit-flags ‘FT_GASP_DO_GRIDFIT’ and ‘FT_GASP_DO_GRAY’ are to be used for standard font rasterization only. Independently of that, ‘FT_GASP_SYMMETRIC_SMOOTHING’ and ‘FT_GASP_SYMMETRIC_GRIDFIT’ are to be used if ClearType is enabled (and ‘FT_GASP_DO_GRIDFIT’ and ‘FT_GASP_DO_GRAY’ are consequently ignored).

-

‘ClearType’ is Microsoft's implementation of LCD rendering, partly protected by patents.

FT_Glyph

-
-Defined in FT_GLYPH_H (freetype/ftglyph.h). -

-
-
-  typedef struct FT_GlyphRec_*  FT_Glyph;
-
-

-
-

Handle to an object used to model generic glyph images. It is a pointer to the FT_GlyphRec structure and can contain a glyph bitmap or pointer.

-

-
note
-

Glyph objects are not owned by the library. You must thus release them manually (through FT_Done_Glyph) before calling FT_Done_FreeType.

-

You can typecast an FT_Glyph to FT_BitmapGlyph if you have ‘glyph->format == FT_GLYPH_FORMAT_BITMAP’. This lets you access the bitmap's contents easily.

-

The corresponding pixel buffer is always owned by FT_BitmapGlyph and is thus created and destroyed with it.

You can typecast an FT_Glyph to FT_OutlineGlyph if you have ‘glyph->format == FT_GLYPH_FORMAT_OUTLINE’. This lets you access the outline's content easily.

-

As the outline is extracted from a glyph slot, its coordinates are expressed normally in 26.6 pixels, unless the flag FT_LOAD_NO_SCALE was used in FT_Load_Glyph() or FT_Load_Char().

-

The outline's tables are always owned by the object and are destroyed with it.

FT_Glyph_Get_CBox

-
-Defined in FT_GLYPH_H (freetype/ftglyph.h). -

-
-
-  FT_EXPORT( void )
-  FT_Glyph_Get_CBox( FT_Glyph  glyph,
-                     FT_UInt   bbox_mode,
-                     FT_BBox  *acbox );
-
-

-
-

Return a glyph's ‘control box’. The control box encloses all the outline's points, including Bézier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline which contains Bézier outside arcs).

-

Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the ‘ftbbox’ component which is dedicated to this single task.

-

-
input
-

- - - -
glyph -

A handle to the source glyph object.

-
mode -

The mode which indicates how to interpret the returned bounding box values.

-
-
-
output
-

- - -
acbox -

The glyph coordinate bounding box. Coordinates are expressed in 1/64th of pixels if it is grid-fitted.

-
-
-
note
-

Coordinates are relative to the glyph origin, using the y upwards convention.

-

If the glyph has been loaded with FT_LOAD_NO_SCALE, ‘bbox_mode’ must be set to FT_GLYPH_BBOX_UNSCALED to get unscaled font units in 26.6 pixel format. The value FT_GLYPH_BBOX_SUBPIXELS is another name for this constant.

-

If the font is tricky and the glyph has been loaded with FT_LOAD_NO_SCALE, the resulting CBox is meaningless. To get reasonable values for the CBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the CBox which can be eventually converted back to font units.

-

Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as:

-
-  width  = bbox.xMax - bbox.xMin;                                  
-  height = bbox.yMax - bbox.yMin;                                  
-
-

Note also that for 26.6 coordinates, if ‘bbox_mode’ is set to FT_GLYPH_BBOX_GRIDFIT, the coordinates will also be grid-fitted, which corresponds to:

-
-  bbox.xMin = FLOOR(bbox.xMin);                                    
-  bbox.yMin = FLOOR(bbox.yMin);                                    
-  bbox.xMax = CEILING(bbox.xMax);                                  
-  bbox.yMax = CEILING(bbox.yMax);                                  
-
-

To get the bbox in pixel coordinates, set ‘bbox_mode’ to FT_GLYPH_BBOX_TRUNCATE.

-

To get the bbox in grid-fitted pixel coordinates, set ‘bbox_mode’ to FT_GLYPH_BBOX_PIXELS.

the_glyph -

A pointer to a handle to the target glyph.

-
-
-
input
-

- - - - -
render_mode -

An enumeration that describes how the data is rendered.

-
origin -

A pointer to a vector used to translate the glyph image before rendering. Can be 0 (if no translation). The origin is expressed in 26.6 pixels.

-
destroy -

A boolean that indicates that the original glyph image should be destroyed by this function. It is never destroyed in case of error.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

This function does nothing if the glyph format isn't scalable.

-

The glyph image is translated with the ‘origin’ vector before rendering.

-

The first parameter is a pointer to an FT_Glyph handle, that will be replaced by this function (with newly allocated data). Typically, you would use (omitting error handling):

-

-
-  FT_Glyph        glyph;

This component generates stroked outlines of a given vectorial glyph. It also allows you to retrieve the ‘outside’ and/or the ‘inside’ borders of the stroke.

-

This can be useful to generate ‘bordered’ glyph, i.e., glyphs displayed with a coloured (and anti-aliased) border around their shape.

FT_Stroker

-
-Defined in FT_STROKER_H (freetype/ftstroke.h). -

-
-
-  typedef struct FT_StrokerRec_*  FT_Stroker;
-

-

Opaque handler to a path stroker object.

-    FT_STROKER_LINEJOIN_ROUND          = 0,
-    FT_STROKER_LINEJOIN_BEVEL          = 1,

-

-
-

These values determine how two joining lines are rendered in a stroker.

-

-
values
-

- - - - - - - - - - - -
FT_STROKER_LINEJOIN_ROUND
-

Used to render rounded line joins. Circular arcs are used to join two lines smoothly.

-
FT_STROKER_LINEJOIN_BEVEL
-

Used to render beveled line joins. The outer corner of the joined lines is filled by enclosing the triangular region of the corner with a straight line between the outer corners of each stroke.

-
FT_STROKER_LINEJOIN_MITER_FIXED
-

Used to render mitered line joins, with fixed bevels if the miter limit is exceeded. The outer edges of the strokes for the two segments are extended until they meet at an angle. If the segments meet at too sharp an angle (such that the miter would extend from the intersection of the segments a distance greater than the product of the miter limit value and the border radius), then a bevel join (see above) is used instead. This prevents long spikes being created. FT_STROKER_LINEJOIN_MITER_FIXED generates a miter line join as used in PostScript and PDF.

-
FT_STROKER_LINEJOIN_MITER_VARIABLE
-

-
FT_STROKER_LINEJOIN_MITER
-

Used to render mitered line joins, with variable bevels if the miter limit is exceeded. The intersection of the strokes is clipped at a line perpendicular to the bisector of the angle between the strokes, at the distance from the intersection of the segments equal to the product of the miter limit value and the border radius. This prevents long spikes being created. FT_STROKER_LINEJOIN_MITER_VARIABLE generates a mitered line join as used in XPS. FT_STROKER_LINEJOIN_MITER is an alias for FT_STROKER_LINEJOIN_MITER_VARIABLE, retained for backwards compatibility.

-

-
values
-

- - - - - - - -
FT_STROKER_LINECAP_BUTT
-

The end of lines is rendered as a full stop on the last point itself.

-
FT_STROKER_LINECAP_ROUND
-

The end of lines is rendered as a half-circle around the last point.

-
FT_STROKER_LINECAP_SQUARE

FT_StrokerBorder

-
-Defined in FT_STROKER_H (freetype/ftstroke.h). -

-
-

-  {
-    FT_STROKER_BORDER_LEFT = 0,
-    FT_STROKER_BORDER_RIGHT
-
-  } FT_StrokerBorder;
-
-

-
-

These values are used to select a given stroke border in FT_Stroker_GetBorderCounts and FT_Stroker_ExportBorder.

-

-
values
-

- - - - -
FT_STROKER_BORDER_LEFT -

Select the left border, relative to the drawing direction.

-
FT_STROKER_BORDER_RIGHT
-

Select the right border, relative to the drawing direction.

-
-
-
note
-

Applications are generally interested in the ‘inside’ and ‘outside’ borders. However, there is no direct mapping between these and the ‘left’ and ‘right’ ones, since this really depends on the glyph's drawing orientation, which varies between font formats.

-

You can however use FT_Outline_GetInsideBorder and FT_Outline_GetOutsideBorder to get these.

-

A convenience function used to parse a whole outline with the stroker. The resulting outline(s) can be retrieved later by functions like FT_Stroker_GetCounts and FT_Stroker_Export.

-

-
input
-

- - - - -
stroker -

The target stroker handle.

-
outline -

The source outline.

FreeType error code. 0 means success.

-
-
note
-

If ‘opened’ is 0 (the default), the outline is treated as a closed path, and the stroker generates two distinct ‘border’ outlines.

-

If ‘opened’ is 1, the outline is processed as an open path, and the stroker generates a single ‘stroke’ outline.

-

This function calls FT_Stroker_Rewind automatically.

FT_Face_GetVariantSelectors


- -
-

Many CJK characters have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Ideographic Variation Sequences (IVS), consisting of a Unicode base character and one of 240 variant selectors (U+E0100-U+E01EF), instead of further extending the already huge code range for CJK characters.

-

An IVS is registered and unique; for further details please refer to Unicode Technical Standard #37, the Ideographic Variation Database:

-

http://www.unicode.org/reports/tr37/

-

To date (November 2012), the character with the most variants is U+9089, having 31 such IVS.

-

Adobe and MS decided to support IVS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variants supported by the font.

-

A variant may be either ‘default’ or ‘non-default’. A default variant is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variant is a different glyph.

-                               FT_ULong  variantSelector );
-
-

-
-

Return the glyph index of a given character code as modified by the variation selector.

-

-
input
-

- - - - -
face -

A handle to the source face object.

-
charcode -

The character code point in Unicode.

-
variantSelector -

The Unicode code point of the variation selector.

-
-
-
return
-

The glyph index. 0 means either ‘undefined character code’, or ‘undefined selector code’, or ‘no variation selector cmap subtable’, or ‘current CharMap is not Unicode’.

-
-
note
-

If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file. This is done to ensure that value 0 always corresponds to the ‘missing glyph’.

-

This function is only meaningful if a) the font has a variation selector cmap sub table, and b) the current charmap has a Unicode encoding.

-
-

-
-

Validate various TrueTypeGX tables to assure that all offsets and indices are valid. The idea is that a higher-level library which actually does the text layout can access those tables without error checking (which can be quite time consuming).

-

-
input
-

- - - - -
face -

A handle to the input face.

-
validation_flags -

A bit field which specifies the tables to be validated. See FT_VALIDATE_GXXXX for possible values.

-
table_length -

The size of the ‘tables’ array. Normally, FT_VALIDATE_GX_LENGTH should be passed.

-
-
-
output
-

- - -
tables -

The array where all validated sfnt tables are stored. The array itself must be allocated by a client.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

This function only works with TrueTypeGX fonts, returning an error otherwise.

-

After use, the application should deallocate the buffers pointed to by each ‘tables’ element, by calling FT_TrueTypeGX_Free. A NULL value indicates that the table either doesn't exist in the font, the application hasn't asked for validation, or the validator doesn't have the ability to validate the sfnt table.

A list of bit-field constants used with FT_ClassicKern_Validate to indicate the classic kern dialect or dialects. If the selected type doesn't fit, FT_ClassicKern_Validate regards the table as invalid.

-

-
values
-

- - - - -
FT_VALIDATE_MS -

Handle the ‘kern’ table as a classic Microsoft kern table.

-
FT_VALIDATE_APPLE -

Handle the ‘kern’ table as a classic Apple kern table.

-
FT_VALIDATE_CKERN -

Handle the ‘kern’ as either classic Apple or Microsoft kern table.

FT_ClassicKern_Validate

-
-Defined in FT_GX_VALIDATE_H (freetype/ftgxval.h). -

-
-
-  FT_EXPORT( FT_Error )
-  FT_ClassicKern_Validate( FT_Face    face,
-                           FT_UInt    validation_flags,
-                           FT_Bytes  *ckern_table );
-
-

-
-

Validate classic (16-bit format) kern table to assure that the offsets and indices are valid. The idea is that a higher-level library which actually does the text layout can access those tables without error checking (which can be quite time consuming).

-

The ‘kern’ table validator in FT_TrueTypeGX_Validate deals with both the new 32-bit format and the classic 16-bit format, while FT_ClassicKern_Validate only supports the classic 16-bit format.

-

-
input
-

- - - -
face -

A handle to the input face.

-
validation_flags -

A bit field which specifies the dialect to be validated. See FT_VALIDATE_CKERNXXX for possible values.

-
-
-
output
-

- - -
ckern_table -

A pointer to the kern table.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

After use, the application should deallocate the buffers pointed to by ‘ckern_table’, by calling FT_ClassicKern_Free. A NULL value indicates that the table doesn't exist in the font.

FT_Stream_OpenGzip


- -
-

This section contains the declaration of Gzip-specific functions.

-

-
-

FT_Stream_OpenGzip

-
-Defined in FT_GZIP_H (freetype/ftgzip.h). -

-
-
-  FT_EXPORT( FT_Error )
-  FT_Stream_OpenGzip( FT_Stream  stream,
-                      FT_Stream  source );
-
-

-
-

Open a new stream to parse gzip-compressed font files. This is mainly used to support the compressed ‘*.pcf.gz’ fonts that come with XFree86.

-

-
input
-

- - - -
stream -

The target embedding stream.

-
source -

The source stream.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

The source stream must be opened before calling this function.

-

Calling the internal function ‘FT_Stream_Close’ on the new stream will not call ‘FT_Stream_Close’ on the source stream. None of the stream objects will be released to the heap.

-

The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.

-

In certain builds of the library, gzip compression recognition is automatically handled when calling FT_New_Face or FT_Open_Face. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a gzipped stream from it and re-open the face with it.

-

This function may return ‘FT_Err_Unimplemented_Feature’ if your build of FreeType was not compiled with zlib support.

The following macros are defined to the name of specific FreeType 2 header files. They can be used directly in #include statements as in:

-
-  #include FT_FREETYPE_H                                           
-  #include FT_MULTIPLE_MASTERS_H                                   
-  #include FT_GLYPH_H                                              
-
-

There are several reasons why we are now using macros to name public header files. The first one is that such macros are not limited to the infamous 8.3 naming rule required by DOS (and ‘FT_MULTIPLE_MASTERS_H’ is a lot more meaningful than ‘ftmm.h’).

-

The second reason is that it allows for more flexibility in the way FreeType 2 is installed on a given system.

- -
-

This section contains various functions used to perform so-called ‘incremental’ glyph loading. This is a mode where all glyphs loaded from a given FT_Face are provided by the client application,

-

Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor.

-

To enable this mode, you must use FT_Open_Face, passing an FT_Parameter with the FT_PARAM_TAG_INCREMENTAL tag and an FT_Incremental_Interface value. See the comments for FT_Incremental_InterfaceRec for an example.

FT_Incremental

-
-Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). -

-
-
-  typedef struct FT_IncrementalRec_*  FT_Incremental;
-
-

-
-

An opaque type describing a user-provided object used to implement ‘incremental’ glyph loading within FreeType. This is used to support embedded fonts in certain environments (e.g., PostScript interpreters), where the glyph data isn't in the font file, or must be overridden by different values.

-

-
note
-

It is up to client applications to create and implement FT_Incremental objects, as long as they provide implementations for the methods FT_Incremental_GetGlyphDataFunc, FT_Incremental_FreeGlyphDataFunc and FT_Incremental_GetGlyphMetricsFunc.

-

See the description of FT_Incremental_InterfaceRec to understand how to use incremental objects with FreeType.

-  {
-    FT_Long  bearing_x;
-    FT_Long  bearing_y;
-    FT_Long  advance;
-    FT_Long  advance_v;     /* since 2.3.12 */
-
-  } FT_Incremental_MetricsRec;
-
-

-
-

-

-
fields
-

- - - - - -
bearing_x -

Left bearing, in font units.

-
bearing_y -

Top bearing, in font units.

-
advance -

Horizontal component of glyph advance, in font units.

-
advance_v -

Vertical component of glyph advance, in font units.

-
-
-
note
-

These correspond to horizontal or vertical metrics depending on the value of the ‘vertical’ argument to the function FT_Incremental_GetGlyphMetricsFunc.

FT_Incremental_Metrics

-
-Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). -

-
-

FT_Incremental_GetGlyphDataFunc

-
-Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). -

-
-
-  typedef FT_Error
-  (*FT_Incremental_GetGlyphDataFunc)( FT_Incremental  incremental,
-                                      FT_UInt         glyph_index,
-                                      FT_Data*        adata );
-
-

-
-

A function called by FreeType to access a given glyph's data bytes during FT_Load_Glyph or FT_Load_Char if incremental loading is enabled.

-

Note that the format of the glyph's data bytes depends on the font file format. For TrueType, it must correspond to the raw bytes within the ‘glyf’ table. For PostScript formats, it must correspond to the unencrypted charstring bytes, without any ‘lenIV’ header. It is undefined for any other format.

-

-
input
-

- - - -
incremental -

Handle to an opaque FT_Incremental handle provided by the client application.

-
glyph_index -

Index of relevant glyph.

-
-
-
output
-

- - -
adata -

A structure describing the returned glyph data bytes (which will be accessed as a read-only byte block).

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

If this function returns successfully the method FT_Incremental_FreeGlyphDataFunc will be called later to release the data bytes.

-

Nested calls to FT_Incremental_GetGlyphDataFunc can happen for compound glyphs.

-                                       FT_Data*        data );
-
-

-
-

A function used to release the glyph data bytes returned by a successful call to FT_Incremental_GetGlyphDataFunc.

-

-
input
-

- - - -
incremental -

A handle to an opaque FT_Incremental handle provided by the client application.

-
data -

A structure describing the glyph data bytes (which will be accessed as a read-only byte block).

FT_Incremental_GetGlyphMetricsFunc

-
-Defined in FT_INCREMENTAL_H (freetype/ftincrem.h). -

-
-
-  typedef FT_Error
-  (*FT_Incremental_GetGlyphMetricsFunc)
-                      ( FT_Incremental              incremental,
-                        FT_UInt                     glyph_index,
-                        FT_Bool                     vertical,
-                        FT_Incremental_MetricsRec  *ametrics );
-
-

-
-

A function used to retrieve the basic metrics of a given glyph index before accessing its data. This is necessary because, in certain formats like TrueType, the metrics are stored in a different place from the glyph images proper.

-

-
input
-

- - - - - -
incremental -

A handle to an opaque FT_Incremental handle provided by the client application.

-
glyph_index -

Index of relevant glyph.

-
vertical -

If true, return vertical metrics.

-
ametrics -

This parameter is used for both input and output. The original glyph metrics, if any, in font units. If metrics are not available all the values must be set to zero.

-
-
-
output
-

- - -
ametrics -

The replacement glyph metrics in font units.

-
-  } FT_Incremental_InterfaceRec;
-
-

-
-

-  FT_Parameter                 parameter;
-  FT_Open_Args                 open_args;
-
-
-  // set up incremental descriptor
-  inc_int.funcs  = my_funcs;
-  inc_int.object = my_object;
-
-  // set up optional parameter
-  parameter.tag  = FT_PARAM_TAG_INCREMENTAL;
-  parameter.data = &inc_int;
-
-  // set up FT_Open_Args structure
-  open_args.flags      = FT_OPEN_PATHNAME | FT_OPEN_PARAMS;
-  open_args.pathname   = my_font_pathname;
-  open_args.num_params = 1;
-  open_args.params     = &parameter; // we use one optional argument
-
-  // open the font
-  error = FT_Open_Face( library, &open_args, index, &face );
-  ...

Synopsis

- - - -
FT_LcdFilterFT_Library_SetLcdFilterWeights
FT_Library_SetLcdFilter


- -
-

The FT_Library_SetLcdFilter API can be used to specify a low-pass filter which is then applied to LCD-optimized bitmaps generated through FT_Render_Glyph. This is useful to reduce color fringes which would occur with unfiltered rendering.

-

Note that no filter is active by default, and that this function is not implemented in default builds of the library. You need to #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your ‘ftoption.h’ file in order to activate it.

-

-
-

FT_LcdFilter

-
-Defined in FT_LCD_FILTER_H (freetype/ftlcdfil.h). -

-
-
-  typedef enum  FT_LcdFilter_
-  {
-    FT_LCD_FILTER_NONE    = 0,
-    FT_LCD_FILTER_DEFAULT = 1,
-    FT_LCD_FILTER_LIGHT   = 2,
-    FT_LCD_FILTER_LEGACY  = 16,
-
-    FT_LCD_FILTER_MAX   /* do not remove */
-
-  } FT_LcdFilter;
-
-

-
-

A list of values to identify various types of LCD filters.

-

-
values
-

- - - - - -
FT_LCD_FILTER_NONE -

Do not perform filtering. When used with subpixel rendering, this results in sometimes severe color fringes.

-
FT_LCD_FILTER_DEFAULT -

The default filter reduces color fringes considerably, at the cost of a slight blurriness in the output.

-
FT_LCD_FILTER_LIGHT -

The light filter is a variant that produces less blurriness at the cost of slightly more color fringes than the default one. It might be better, depending on taste, your monitor, or your personal vision.

-
FT_LCD_FILTER_LEGACY -

This filter corresponds to the original libXft color filter. It provides high contrast output but can exhibit really bad color fringes if glyphs are not extremely well hinted to the pixel grid. In other words, it only works well if the TrueType bytecode interpreter is enabled and high-quality hinted fonts are used.

-

This filter is only provided for comparison purposes, and might be disabled or stay unsupported in the future.

FT_Library_SetLcdFilter

-
-Defined in FT_LCD_FILTER_H (freetype/ftlcdfil.h). -

-
-
-  FT_EXPORT( FT_Error )
-  FT_Library_SetLcdFilter( FT_Library    library,
-                           FT_LcdFilter  filter );
-
-

-
-

This function is used to apply color filtering to LCD decimated bitmaps, like the ones used when calling FT_Render_Glyph with FT_RENDER_MODE_LCD or FT_RENDER_MODE_LCD_V.

-

-
input
-

- - - -
library -

A handle to the target library instance.

-
filter -

The filter type.

-

You can use FT_LCD_FILTER_NONE here to disable this feature, or FT_LCD_FILTER_DEFAULT to use a default filter that should work well on most LCD screens.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

This feature is always disabled by default. Clients must make an explicit call to this function with a ‘filter’ value other than FT_LCD_FILTER_NONE in order to enable it.

-

Due to PATENTS covering subpixel rendering, this function doesn't do anything except returning ‘FT_Err_Unimplemented_Feature’ if the configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not defined in your build of the library, which should correspond to all default builds of FreeType.

-

The filter affects glyph bitmaps rendered through FT_Render_Glyph, FT_Outline_Get_Bitmap, FT_Load_Glyph, and FT_Load_Char.

-

It does not affect the output of FT_Outline_Render and FT_Outline_Get_Bitmap.

-

If this feature is activated, the dimensions of LCD glyph bitmaps are either larger or taller than the dimensions of the corresponding outline with regards to the pixel grid. For example, for FT_RENDER_MODE_LCD, the filter adds up to 3 pixels to the left, and up to 3 pixels to the right.

-

The bitmap offset values are adjusted correctly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.

-                                  unsigned char  *weights );
-
-

-
-

Use this function to override the filter weights selected by FT_Library_SetLcdFilter. By default, FreeType uses the quintuple (0x00, 0x55, 0x56, 0x55, 0x00) for FT_LCD_FILTER_LIGHT, and (0x10, 0x40, 0x70, 0x40, 0x10) for FT_LCD_FILTER_DEFAULT and FT_LCD_FILTER_LEGACY.

-

-
input
-

- - - -
library -

A handle to the target library instance.

-
weights -

A pointer to an array; the function copies the first five bytes and uses them to specify the filter weights.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

Due to PATENTS covering subpixel rendering, this function doesn't do anything except returning ‘FT_Err_Unimplemented_Feature’ if the configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not defined in your build of the library, which should correspond to all default builds of FreeType.

-

This function must be called after FT_Library_SetLcdFilter to have any effect.

This section contains the declaration of LZW-specific functions.

FT_Stream_OpenLZW

-
-Defined in FT_LZW_H (freetype/ftlzw.h). -

-
-
-  FT_EXPORT( FT_Error )
-  FT_Stream_OpenLZW( FT_Stream  stream,
-                     FT_Stream  source );
-
-

-
-

Open a new stream to parse LZW-compressed font files. This is mainly used to support the compressed ‘*.pcf.Z’ fonts that come with XFree86.

-

-
input
-

- - - -
stream -

The target embedding stream.

-
source -

The source stream.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

The source stream must be opened before calling this function.

-

Calling the internal function ‘FT_Stream_Close’ on the new stream will not call ‘FT_Stream_Close’ on the source stream. None of the stream objects will be released to the heap.

-

The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream

-

In certain builds of the library, LZW compression recognition is automatically handled when calling FT_New_Face or FT_Open_Face. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.

-

This function may return ‘FT_Err_Unimplemented_Feature’ if your build of FreeType was not compiled with LZW support.

-
-

-
-

This function is used to create a new FreeType library instance from a given memory object. It is thus possible to use libraries with distinct memory allocators within the same program.

-

Normally, you would call this function (followed by a call to FT_Add_Default_Modules or a series of calls to FT_Add_Module) instead of FT_Init_FreeType to initialize the FreeType library.

-

Don't use FT_Done_FreeType but FT_Done_Library to destroy a library instance.

The index of the debug hook. You should use the values defined in ‘ftobjs.h’, e.g., ‘FT_DEBUG_HOOK_TRUETYPE’.

-
debug_hook -

The function used to debug the interpreter.

-
-
-
note
-

Currently, four debug hook slots are available, but only two (for the TrueType and the Type 1 interpreter) are defined.

-

Since the internal headers of FreeType are no longer installed, the symbol ‘FT_DEBUG_HOOK_TRUETYPE’ isn't available publicly. This is a bug and will be fixed in a forthcoming release.

-
-
note
-

In case of success, the renderer will be used to convert glyph images in the renderer's known format into bitmaps.

-

This doesn't change the current renderer for other formats.

-

Currently, only the B/W renderer, if compiled with FT_RASTER_OPTION_ANTI_ALIASING (providing a 5-levels anti-aliasing mode; this option must be set directly in ‘ftraster.c’ and is undefined by default) accepts a single tag ‘pal5’ to set its gray palette as a character string with 5 elements. Consequently, the third and fourth argument are zero normally.

The following types and functions are used to manage Multiple Master fonts, i.e., the selection of specific design instances by setting design axis coordinates.

-

George Williams has extended this interface to make it work with both Type 1 Multiple Masters fonts and GX distortable (var) fonts. Some of these routines only work with MM fonts, others will work with both types. They are similar enough that a consistent interface makes sense.

- - - - - - - -
n_contours -

The number of contours in the outline.

-
n_points -

The number of points in the outline.

-
points -

A pointer to an array of ‘n_points’ FT_Vector elements, giving the outline's point coordinates.

-
tags -

A pointer to an array of ‘n_points’ chars, giving each outline point's type.

-

If bit 0 is unset, the point is ‘off’ the curve, i.e., a Bézier control point, while it is ‘on’ if set.

-

Bit 1 is meaningful for ‘off’ points only. If set, it indicates a third-order Bézier arc control point; and a second-order control point if unset.

-

If bit 2 is set, bits 5-7 contain the drop-out mode (as defined in the OpenType specification; the value is the same as the argument to the SCANMODE instruction).

-

Bits 3 and 4 are reserved for internal purposes.

-
contours -

An array of ‘n_contours’ shorts, giving the end point of each contour within the outline. For example, the first contour is defined by the points ‘0’ to ‘contours[0]’, the second one is defined by the points ‘contours[0]+1’ to ‘contours[1]’, etc.

-
flags -

A set of bit flags used to characterize the outline and give hints to the scan-converter and hinter on how to convert/grid-fit it. See FT_OUTLINE_FLAGS.

-
-
-
note
-

The B/W rasterizer only checks bit 2 in the ‘tags’ array for the first point of each contour. The drop-out mode as given with FT_OUTLINE_IGNORE_DROPOUTS, FT_OUTLINE_SMART_DROPOUTS, and FT_OUTLINE_INCLUDE_STUBS in ‘flags’ is then overridden.

A list of bit-field constants use for the flags in an outline's ‘flags’ field.

-

-
values
-

- - - - - - - - - - - - - - - - -
FT_OUTLINE_NONE -

Value 0 is reserved.

-
FT_OUTLINE_OWNER -

If set, this flag indicates that the outline's field arrays (i.e., ‘points’, ‘flags’, and ‘contours’) are ‘owned’ by the outline object, and should thus be freed when it is destroyed.

-
FT_OUTLINE_EVEN_ODD_FILL
-

By default, outlines are filled using the non-zero winding rule. If set to 1, the outline will be filled using the even-odd fill rule (only works with the smooth rasterizer).

-
FT_OUTLINE_REVERSE_FILL
-

By default, outside contours of an outline are oriented in clock-wise direction, as defined in the TrueType specification. This flag is set if the outline uses the opposite direction (typically for Type 1 fonts). This flag is ignored by the scan converter.

-
FT_OUTLINE_IGNORE_DROPOUTS
-

By default, the scan converter will try to detect drop-outs in an outline and correct the glyph bitmap to ensure consistent shape continuity. If set, this flag hints the scan-line converter to ignore such cases. See below for more information.

-
FT_OUTLINE_SMART_DROPOUTS
-

Select smart dropout control. If unset, use simple dropout control. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information.

-
FT_OUTLINE_INCLUDE_STUBS
-

If set, turn pixels on for ‘stubs’, otherwise exclude them. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information.

-
FT_OUTLINE_HIGH_PRECISION
-

This flag indicates that the scan-line converter should try to convert this outline to bitmaps with the highest possible quality. It is typically set for small character sizes. Note that this is only a hint that might be completely ignored by a given scan-converter.

-
FT_OUTLINE_SINGLE_PASS -

This flag is set to force a given scan-converter to only use a single pass over the outline to render a bitmap glyph image. Normally, it is set for very large character sizes. It is only a hint that might be completely ignored by a given scan-converter.

-
-
-
note
-

The flags FT_OUTLINE_IGNORE_DROPOUTS, FT_OUTLINE_SMART_DROPOUTS, and FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth rasterizer.

-

There exists a second mechanism to pass the drop-out mode to the B/W rasterizer; see the ‘tags’ field in FT_Outline.

-

Please refer to the description of the ‘SCANTYPE’ instruction in the OpenType specification (in file ‘ttinst1.doc’) how simple drop-outs, smart drop-outs, and stubs are defined.

return
-

FreeType error code. 0 means success.

-
-
note
-

The used algorithm to increase or decrease the thickness of the glyph doesn't change the number of points; this means that certain situations like acute angles or intersections are sometimes handled incorrectly.

-

If you need ‘better’ metrics values you should call FT_Outline_Get_CBox or FT_Outline_Get_BBox.

-

Example call:

-
-  FT_Load_Glyph( face, index, FT_LOAD_DEFAULT );                   
-  if ( face->slot->format == FT_GLYPH_FORMAT_OUTLINE )

-                       FT_BBox     *abbox );
-
-

-
-

Compute the exact bounding box of an outline. This is slower than computing the control box. However, it uses an advanced algorithm which returns very quickly when the two boxes coincide. Otherwise, the outline Bézier arcs are traversed to extract their extrema.

-

-
input
-

- - -
outline -

A pointer to the source outline.

-
-
-
output
-

- - -
abbox -

The outline's exact bounding box.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

If the font is tricky and the glyph has been loaded with FT_LOAD_NO_SCALE, the resulting BBox is meaningless. To get reasonable values for the BBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the BBox which can be eventually converted back to font units.

The point coordinates sent to the emitters are the transformed version of the original coordinates (this is important for high accuracy during scan-conversion). The transformation is simple:

-
-  x' = (x << shift) - delta                                        
-  y' = (x << shift) - delta                                        
-

-

-
-

Return an outline's ‘control box’. The control box encloses all the outline's points, including Bézier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline which contains Bézier outside arcs).

-

Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the ‘ftbbox’ component which is dedicated to this single task.

-
-

Render an outline within a bitmap. The outline's image is simply OR-ed to the target bitmap.

-

- - - -
library -

A handle to a FreeType library object.

FreeType error code. 0 means success.

-
-
note
-

This function does NOT CREATE the bitmap, it only renders an outline image within the one you pass to it! Consequently, the various fields in ‘abitmap’ should be set accordingly.

-

It will use the raster corresponding to the default glyph format.

-

The value of the ‘num_grays’ field in ‘abitmap’ is ignored. If you select the gray-level rasterizer, and you want less than 256 gray levels, you have to use FT_Outline_Render directly.

FT_Outline_Render

-
-Defined in FT_OUTLINE_H (freetype/ftoutln.h). -

-                     FT_Raster_Params*  params );
-
-

-
-

Render an outline within a bitmap using the current scan-convert. This function uses an FT_Raster_Params structure as an argument, allowing advanced features like direct composition, translucency, etc.

-

-
input
-

- - - -
library -

A handle to a FreeType library object.

-
outline -

A pointer to the source outline descriptor.

-
-
-
inout
-

- - -
params -

A pointer to an FT_Raster_Params structure used to describe the rendering operation.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

You should know what you are doing and how FT_Raster_Params works to use this function.

-

The field ‘params.source’ will be set to ‘outline’ before the scan converter is called, which means that the value you give to it is actually ignored.

-

The gray-level rasterizer always uses 256 gray levels. If you want less gray levels, you have to provide your own span callback. See the FT_RASTER_FLAG_DIRECT value of the ‘flags’ field in the FT_Raster_Params structure for more details.

The TrueType and PostScript specifications use different conventions to determine whether outline contours should be filled or unfilled.

-

-
values
-

- - - - - - - - - - -
FT_ORIENTATION_TRUETYPE
-

According to the TrueType specification, clockwise contours must be filled, and counter-clockwise ones must be unfilled.

-
FT_ORIENTATION_POSTSCRIPT
-

According to the PostScript specification, counter-clockwise contours must be filled, and clockwise ones must be unfilled.

-
FT_ORIENTATION_FILL_RIGHT
-

This is identical to FT_ORIENTATION_TRUETYPE, but is used to remember that in TrueType, everything that is to the right of the drawing direction of a contour must be filled.

-
FT_ORIENTATION_FILL_LEFT
-

This is identical to FT_ORIENTATION_POSTSCRIPT, but is used to remember that in PostScript, everything that is to the left of the drawing direction of a contour must be filled.

-
FT_ORIENTATION_NONE -

The orientation cannot be determined. That is, different parts of the glyph have different orientation.

-
-
-  FT_EXPORT( FT_Orientation )
-  FT_Outline_Get_Orientation( FT_Outline*  outline );
-
-

-
-

This function analyzes a glyph outline and tries to compute its fill orientation (see FT_Orientation). This is done by computing the direction of each global horizontal and/or vertical extrema within the outline.

input
-

- - -
face -

Handle to the input face. It can be a non-PFR face.

-
-
-
output
-

- - - - - -
aoutline_resolution -

Outline resolution. This is equivalent to ‘face->units_per_EM’ for non-PFR fonts. Optional (parameter can be NULL).

-
ametrics_resolution -

Metrics resolution. This is equivalent to ‘outline_resolution’ for non-PFR fonts. Optional (parameter can be NULL).

-
ametrics_x_scale -

A 16.16 fixed-point number used to scale distance expressed in metrics units to device sub-pixels. This is equivalent to ‘face->size->x_scale’, but for metrics only. Optional (parameter can be NULL).

-
ametrics_y_scale -

Same as ‘ametrics_x_scale’ but for the vertical direction. optional (parameter can be NULL).

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note

FT_ADVANCE_FLAG_FAST_ONLYFT_Get_Advances
FT_Get_Advance


- -
-

This section contains functions to quickly extract advance values without handling glyph outlines, if possible.

-

-
-

FT_ADVANCE_FLAG_FAST_ONLY

-
-Defined in FT_ADVANCES_H (freetype/ftadvanc.h). -

-
-
-#define FT_ADVANCE_FLAG_FAST_ONLY  0x20000000UL
-
-

-
-

A bit-flag to be OR-ed with the ‘flags’ parameter of the FT_Get_Advance and FT_Get_Advances functions.

-

If set, it indicates that you want these functions to fail if the corresponding hinting mode or font driver doesn't allow for very quick advance computation.

-

Typically, glyphs which are either unscaled, unhinted, bitmapped, or light-hinted can have their advance width computed very quickly.

-

Normal and bytecode hinted modes, which require loading, scaling, and hinting of the glyph outline, are extremely slow by comparison.

face -

The source FT_Face handle.

-
gindex -

The glyph index.

-
load_flags -

A set of bit flags similar to those used when calling FT_Load_Glyph, used to determine what kind of advances you need.

-
-
-
output
-

- - -
padvance -

The advance value, in either font units or 16.16 format.

-

If FT_LOAD_VERTICAL_LAYOUT is set, this is the vertical advance corresponding to a vertical layout. Otherwise, it is the horizontal advance in a horizontal layout.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

This function may fail if you use FT_ADVANCE_FLAG_FAST_ONLY and if the corresponding font backend doesn't have a quick way to retrieve the advances.

-

A scaled advance is returned in 16.16 format but isn't transformed by the affine transformation specified by FT_Set_Transform.

-    unsigned short  len;
-    unsigned char   coverage;
-
-  } FT_Span;
-
-

-
-

A structure used to model a single span of gray (or black) pixels when rendering a monochrome or anti-aliased bitmap.

-

-
fields
-

- - - - -
x -

The span's horizontal start position.

-
len -

The span's length in pixels.

-
coverage -

The span color/coverage, ranging from 0 (background) to 255 (foreground). Only used for anti-aliased rendering.

-
-
-
note
-

This structure is used by the span drawing callback type named FT_SpanFunc which takes the y coordinate of the span as a a parameter.

-

The coverage value is always between 0 and 255. If you want less gray values, the callback function has to reduce them.

-                  void*           user );
-
-#define FT_Raster_Span_Func  FT_SpanFunc
-
-

-
-

A function used as a call-back by the anti-aliased renderer in order to let client applications draw themselves the gray pixel spans on each scan line.

-

-
input
-

- - - - - -
y -

The scanline's y coordinate.

-
count -

The number of spans to draw on this scanline.

-
spans -

A table of ‘count’ spans to draw on the scanline.

-
user -

User-supplied data that is passed to the callback.

-
-
-
note
-

This callback allows client applications to directly render the gray spans of the anti-aliased bitmap to any kind of surfaces.

-

This can be used to write anti-aliased outlines directly to a given background bitmap, and even perform translucency.

-

Note that the ‘count’ field cannot be greater than a fixed value defined by the ‘FT_MAX_GRAY_SPANS’ configuration macro in ‘ftoption.h’. By default, this value is set to 32, which means that if there are more than 32 spans on a given scanline, the callback is called several times with the same ‘y’ parameter in order to draw all callbacks.

-

Otherwise, the callback is only called once per scan-line, and only for those scanlines that do have ‘gray’ pixels on them.

-

-
values
-

- - - - - -
FT_RASTER_FLAG_DEFAULT -

This value is 0.

-
FT_RASTER_FLAG_AA -

This flag is set to indicate that an anti-aliased glyph image should be generated. Otherwise, it will be monochrome (1-bit).

-
FT_RASTER_FLAG_DIRECT -

This flag is set to indicate direct rendering. In this mode, client applications must provide their own span callback. This lets them directly draw or compose over an existing bitmap. If this bit is not set, the target pixmap's buffer must be zeroed before rendering.

-

Note that for now, direct rendering is only possible with anti-aliased glyphs.

-
FT_RASTER_FLAG_CLIP -

This flag is only used in direct rendering mode. If set, the output will be clipped to a box specified in the ‘clip_box’ field of the FT_Raster_Params structure.

-

Note that by default, the glyph bitmap is clipped to the target pixmap, except in direct rendering mode where all spans are generated if no clipping box is set.

A structure to hold the arguments used by a raster's render function.

-

-
fields
-

- - - - - - - - - - -
target -

The target bitmap.

-
source -

A pointer to the source glyph image (e.g., an FT_Outline).

-
flags -

The rendering flags.

-
gray_spans -

The gray span drawing callback.

-
black_spans -

The black span drawing callback. UNIMPLEMENTED!

-
bit_test -

The bit test callback. UNIMPLEMENTED!

-
bit_set -

The bit set callback. UNIMPLEMENTED!

-
user -

User-supplied data that is passed to each drawing callback.

-
clip_box -

An optional clipping box. It is only used in direct rendering mode. Note that coordinates here should be expressed in integer pixels (and not in 26.6 fixed-point units).

-
-
-
note
-

An anti-aliased glyph bitmap is drawn if the FT_RASTER_FLAG_AA bit flag is set in the ‘flags’ field, otherwise a monochrome bitmap is generated.

-

If the FT_RASTER_FLAG_DIRECT bit flag is set in ‘flags’, the raster will call the ‘gray_spans’ callback to draw gray pixel spans, in the case of an aa glyph bitmap, it will call ‘black_spans’, and ‘bit_test’ and ‘bit_set’ in the case of a monochrome bitmap. This allows direct composition over a pre-existing bitmap through user-provided callbacks to perform the span drawing/composition.

-

Note that the ‘bit_test’ and ‘bit_set’ callbacks are required when rendering a monochrome bitmap, as they are crucial to implement correct drop-out control as defined in the TrueType specification.

-
-#define FT_Raster_Reset_Func  FT_Raster_ResetFunc
-
-

-
-

FreeType provides an area of memory called the ‘render pool’, available to all registered rasters. This pool can be freely used during a given scan-conversion but is shared by all rasters. Its content is thus transient.

-

This function is called each time the render pool changes, or just after a new raster object is created.

-

-
input
-

- - - - -
raster -

A handle to the new raster object.

-
pool_base -

The address in memory of the render pool.

-
pool_size -

The size in bytes of the render pool.

-
-
-
note
-

Rasters can ignore the render pool and rely on dynamic memory allocation if they want to (a handle to the memory allocator is passed to the raster constructor). However, this is not recommended for efficiency purposes.

-
-

Invoke a given raster to scan-convert a given glyph image into a target bitmap.

-

-
input
-

raster -

A handle to the raster object.

-
params -

A pointer to an FT_Raster_Params structure used to store the rendering parameters.

-
-
-
return
-

Error code. 0 means success.

-
-
note
-

The exact format of the source image depends on the raster's glyph format defined in its FT_Raster_Funcs structure. It can be an FT_Outline or anything else in order to support a large array of glyph formats.

-

Note also that the render function can fail and return a ‘FT_Err_Unimplemented_Feature’ error code if the raster used does not support direct composition.

-

XXX: For now, the standard raster doesn't support direct composition but this should change for the final release (see the files ‘demos/src/ftgrays.c’ and ‘demos/src/ftgrays2.c’ for examples of distinct implementations which support direct composition).

Synopsis

FT_New_SizeFT_Done_SizeFT_Activate_Size


- -
-

When creating a new face object (e.g., with FT_New_Face), an FT_Size object is automatically created and used to store all pixel-size dependent information, available in the ‘face->size’ field.

-

It is however possible to create more sizes for a given face, mostly in order to manage several character pixel sizes of the same font family and style. See FT_New_Size and FT_Done_Size.

-

Note that FT_Set_Pixel_Sizes and FT_Set_Char_Size only modify the contents of the current ‘active’ size; you thus need to use FT_Activate_Size to change it.

-

99% of applications won't need the functions provided here, especially if they use the caching sub-system, so be cautious when using these.

-

-
-

FT_New_Size

-
-Defined in FT_SIZES_H (freetype/ftsizes.h). -

-
-
-  FT_EXPORT( FT_Error )
-  FT_New_Size( FT_Face   face,
-               FT_Size*  size );
-
-

-
-

Create a new size object from a given face object.

-

-
input
-

- - -
face -

A handle to a parent face object.

-
-
-
output
-

- - -
asize -

A handle to a new size object.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

You need to call FT_Activate_Size in order to select the new size for upcoming calls to FT_Set_Pixel_Sizes, FT_Set_Char_Size, FT_Load_Glyph, FT_Load_Char, etc.

-
-
-  FT_EXPORT( FT_Error )

-
-

-
-

Discard a given size object. Note that FT_Done_Face automatically discards all size objects allocated with FT_New_Size.

-

-
input
-

- - -
size -

-
-
-  FT_EXPORT( FT_Error )
-  FT_Activate_Size( FT_Size  size );
-
-

-
-

Even though it is possible to create several size objects for a given face (see FT_New_Size for details), functions like FT_Load_Glyph or FT_Load_Char only use the one which has been activated last to determine the ‘current character pixel size’.

-

This function can be used to ‘activate’ a previously created size object.

-

-
input
-

- - -
size -

A handle to a target size object.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

If ‘face’ is the size's parent face object, this function changes the value of ‘face->size’ to the input size handle.

-    FT_TRUETYPE_ENGINE_TYPE_PATENTED
-
-  } FT_TrueTypeEngineType;
-
-

-
-

A list of values describing which kind of TrueType bytecode engine is implemented in a given FT_Library instance. It is used by the FT_Get_TrueType_Engine_Type function.

-

-
values
-

- - - - - - - -
FT_TRUETYPE_ENGINE_TYPE_NONE
-

The library doesn't implement any kind of bytecode interpreter.

-
FT_TRUETYPE_ENGINE_TYPE_UNPATENTED
-

The library implements a bytecode interpreter that doesn't support the patented operations of the TrueType virtual machine.

-

Its main use is to load certain Asian fonts which position and scale glyph components with bytecode instructions. It produces bad output for most other fonts.

-
FT_TRUETYPE_ENGINE_TYPE_PATENTED
-

The library implements a bytecode interpreter that covers the full instruction set of the TrueType virtual machine (this was governed by patents until May 2010, hence the name).

values
-

- - - - - - - - -
TT_PLATFORM_APPLE_UNICODE
-

Used by Apple to indicate a Unicode character map and/or name entry. See TT_APPLE_ID_XXX for corresponding ‘encoding_id’ values. Note that name entries in this format are coded as big-endian UCS-2 character codes only.

-
TT_PLATFORM_MACINTOSH -

Used by Apple to indicate a MacOS-specific charmap and/or name entry. See TT_MAC_ID_XXX for corresponding ‘encoding_id’ values. Note that most TrueType fonts contain an Apple roman charmap to be usable on MacOS systems (even if they contain a Microsoft charmap as well).

-
TT_PLATFORM_ISO -

This value was used to specify ISO/IEC 10646 charmaps. It is however now deprecated. See TT_ISO_ID_XXX for a list of corresponding ‘encoding_id’ values.

-
TT_PLATFORM_MICROSOFT -

Used by Microsoft to indicate Windows-specific charmaps. See TT_MS_ID_XXX for a list of corresponding ‘encoding_id’ values. Note that most fonts contain a Unicode charmap using (TT_PLATFORM_MICROSOFT, TT_MS_ID_UNICODE_CS).

-
TT_PLATFORM_CUSTOM -

Used to indicate application-specific charmaps.

-
TT_PLATFORM_ADOBE -

This value isn't part of any font format specification, but is used by FreeType to report Adobe-specific charmaps in an FT_CharMapRec structure. See TT_ADOBE_ID_XXX.

-

-
fields
-

- - - - - - - - - - - - - - - - -
Version -

The table version.

-
Ascender -

The font's ascender, i.e., the distance from the baseline to the top-most of all glyph points found in the font.

-

This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII).

-

You should use the ‘sTypoAscender’ field of the OS/2 table instead if you want the correct one.

-
Descender -

The font's descender, i.e., the distance from the baseline to the bottom-most of all glyph points found in the font. It is negative.

-

This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII).

-

You should use the ‘sTypoDescender’ field of the OS/2 table instead if you want the correct one.

-
Line_Gap -

The font's line gap, i.e., the distance to add to the ascender and descender to get the BTB, i.e., the baseline-to-baseline distance for the font.

-
advance_Width_Max -

This field is the maximum of all advance widths found in the font. It can be used to compute the maximum width of an arbitrary string of text.

-
min_Left_Side_Bearing -

The minimum left side bearing of all glyphs within the font.

-
min_Right_Side_Bearing -

The minimum right side bearing of all glyphs within the font.

-
xMax_Extent -

The maximum horizontal extent (i.e., the ‘width’ of a glyph's bounding box) for all glyphs in the font.

-
caret_Slope_Rise -

The rise coefficient of the cursor's slope of the cursor (slope=rise/run).

-
caret_Slope_Run -

The run coefficient of the cursor's slope.

-
Reserved -

8 reserved bytes.

-
metric_Data_Format -

Always 0.

-
number_Of_HMetrics -

Number of HMetrics entries in the ‘hmtx’ table -- this value can be smaller than the total number of glyphs in the font.

-
long_metrics -

A pointer into the ‘hmtx’ table.

-
short_metrics -

A pointer into the ‘hmtx’ table.

-
-
-
note
-

IMPORTANT: The TT_HoriHeader and TT_VertHeader structures should be identical except for the names of their fields which are different.

-

This ensures that a single function in the ‘ttload’ module is able to read both the horizontal and vertical headers.

The font's descender, i.e., the distance from the baseline to the bottom-most of all glyph points found in the font. It is negative.

-

This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII).

-

You should use the ‘sTypoDescender’ field of the OS/2 table instead if you want the correct one.

-
Line_Gap -

The font's line gap, i.e., the distance to add to the ascender and descender to get the BTB, i.e., the baseline-to-baseline distance for the font.

-
advance_Height_Max -

This field is the maximum of all advance heights found in the font. It can be used to compute the maximum height of an arbitrary string of text.

-
min_Top_Side_Bearing -

The minimum top side bearing of all glyphs within the font.

-
min_Bottom_Side_Bearing
-

The minimum bottom side bearing of all glyphs within the font.

-
yMax_Extent -

The maximum vertical extent (i.e., the ‘height’ of a glyph's bounding box) for all glyphs in the font.

-
caret_Slope_Rise -

The rise coefficient of the cursor's slope of the cursor (slope=rise/run).

-
caret_Slope_Run -

The run coefficient of the cursor's slope.

-
caret_Offset -

The cursor's offset for slanted fonts. This value is ‘reserved’ in vmtx version 1.0.

-
Reserved -

8 reserved bytes.

-
metric_Data_Format -

Always 0.

-
number_Of_HMetrics -

Number of VMetrics entries in the ‘vmtx’ table -- this value can be smaller than the total number of glyphs in the font.

-
long_metrics -

A pointer into the ‘vmtx’ table.

-
short_metrics -

A pointer into the ‘vmtx’ table.

-
-
-
note
-

IMPORTANT: The TT_HoriHeader and TT_VertHeader structures should be identical except for the names of their fields which are different.

-

This ensures that a single function in the ‘ttload’ module is able to read both the horizontal and vertical headers.

-

Use a typecast according to ‘tag’ to access the structure elements.

-
-
note
-

The table is owned by the face object and disappears with it.

-

This function is only useful to access SFNT tables that are loaded by the sfnt, truetype, and opentype drivers. See FT_Sfnt_Tag for a list.

-                      FT_ULong*  length );
-
-

-
-

Load any font table into client memory.

-

-
input
-

- - - - -
face -

A handle to the source face.

-
tag -

The four-byte tag of the table to load. Use the value 0 if you want to access the whole font file. Otherwise, you can use one of the definitions found in the FT_TRUETYPE_TAGS_H file, or forge a new one with FT_MAKE_TAG.

-
offset -

The starting offset in the table (or file if tag == 0).

-
-
-
output
-

- - -
buffer -

The target buffer address. The client must ensure that the memory array is big enough to hold the data.

-
-
-
inout
-

- - -
length -

If the ‘length’ parameter is NULL, then try to load the whole table. Return an error code if it fails.

-

Else, if ‘*length’ is 0, exit immediately while returning the table's (or file) full size in it.

-

Else the number of bytes to read from the table or file, from the starting offset.

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note
-

If you need to determine the table's length you should first call this function with ‘*length’ set to 0, as in the following example:

-
-  FT_ULong  length = 0;
-
-
-  error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length );
-  if ( error ) { ... table does not exist ... }
-
-  buffer = malloc( length );
-  if ( buffer == NULL ) { ... not enough memory ... }
-
-  error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length );
-  if ( error ) { ... could not load table ... }

-

Return information on an SFNT table.

-

-
input
-

- - - -
face -

A handle to the source face.

-
table_index -

The index of an SFNT table. The function returns FT_Err_Table_Missing for an invalid value.

-
-
-
inout
-

- - -
tag -

The name tag of the SFNT table. If the value is NULL, ‘table_index’ is ignored, and ‘length’ returns the number of SFNT tables in the font.

-
-
-
output
-

- - -
length -

The length of the SFNT table (or the number of SFNT tables, depending on ‘tag’).

-
-
-
return
-

FreeType error code. 0 means success.

-
-
note

-
-

-
-

Retrieve the value for the supplied key from a PostScript font.

-

-
input
-

- - - - - - -
face -

PostScript face handle.

-
key -

An enumeration value representing the dictionary key to retrieve.

-
idx -

For array values, this specifies the index to be returned.

-
value -

A pointer to memory into which to write the value.

-
valen_len -

The size, in bytes, of the memory supplied for the value.

-
-
-
output
-

- - -
value -

The value matching the above key, if it exists.

-
-
-
return
-

The amount of memory (in bytes) required to hold the requested value (if it exists, -1 otherwise).

-
-
note
-

The values returned are not pointers into the internal structures of the face, but are ‘fresh’ copies, so that the memory containing them belongs to the calling application. This also enforces the ‘read-only’ nature of these values, i.e., this function cannot be used to manipulate the face.

-

‘value’ is a void pointer because the values returned can be of various types.

-

If either ‘value’ is NULL or ‘value_len’ is too small, just the required memory size for the requested entry is returned.

-

The ‘idx’ parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values.

-

PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).

-

IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either.

-

If the font's format is not PostScript-based, this function returns the ‘FT_Err_Invalid_Argument’ error code.

-User allocation -

-
-

FreeType assumes that structures allocated by the user and passed as arguments are zeroed out except for the actual data. In other words, it is recommended to use ‘calloc’ (or variants of it) instead of ‘malloc’ for allocation.

-
note
-

The reason why this function takes a ‘library’ argument is because certain programs implement library initialization in a custom way that doesn't use FT_Init_FreeType.

- - - - - - - - - - - - - - - - - - - - -
FT_WinFNT_ID_DEFAULT -

This is used for font enumeration and font creation as a ‘don't care’ value. Valid font files don't contain this value. When querying for information about the character set of the font that is currently selected into a specified device context, this return value (of the related Windows API) simply denotes failure.

-
FT_WinFNT_ID_SYMBOL -

There is no known mapping table available.

-
FT_WinFNT_ID_MAC -

Mac Roman encoding.

-
FT_WinFNT_ID_OEM -

From Michael Pöttgen <michael@poettgen.de>:

-

The ‘Windows Font Mapping’ article says that FT_WinFNT_ID_OEM is used for the charset of vector fonts, like ‘modern.fon’, ‘roman.fon’, and ‘script.fon’ on Windows.

-

The ‘CreateFont’ documentation says: The FT_WinFNT_ID_OEM value specifies a character set that is operating-system dependent.

-

The ‘IFIMETRICS’ documentation from the ‘Windows Driver Development Kit’ says: This font supports an OEM-specific character set. The OEM character set is system dependent.

-

In general OEM, as opposed to ANSI (i.e., cp1252), denotes the second default codepage that most international versions of Windows have. It is one of the OEM codepages from

-

http://www.microsoft.com/globaldev/reference/cphome.mspx,

-

and is used for the ‘DOS boxes’, to support legacy applications. A German Windows version for example usually uses ANSI codepage 1252 and OEM codepage 850.

-
FT_WinFNT_ID_CP874 -

A superset of Thai TIS 620 and ISO 8859-11.

-
FT_WinFNT_ID_CP932 -

A superset of Japanese Shift-JIS (with minor deviations).

Note that - * the cache only stores and compares these values, and doesn't try to - * interpret them in any way. - * - * Second, the cache calls, only when needed, a client-provided function - * to convert an @FTC_FaceID into a new @FT_Face object. The latter is - * then completely managed by the cache, including its termination - * through @FT_Done_Face. To monitor termination of face objects, the - * finalizer callback in the `generic' field of the @FT_Face object can - * be used, which might also be used to store the @FTC_FaceID of the - * face. - * - * Clients are free to map face IDs to anything else. The most simple - * usage is to associate them to a (pathname,face_index) pair that is - * used to call @FT_New_Face. However, more complex schemes are also - * possible. - * - * Note that for the cache to work correctly, the face ID values must be - * *persistent*, which means that the contents they point to should not - * change at runtime, or that their value should not become invalid. - * - * If this is unavoidable (e.g., when a font is uninstalled at runtime), - * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let - * the cache get rid of any references to the old @FTC_FaceID it may - * keep internally.

An edge corresponds to a single position on the main - * dimension that collects one or more segments (allowing for a small - * threshold). - * - * The auto-hinter first tries to grid fit edges, then to align - * segments on the edges unless it detects that they form a serif. - * - * `af_{cjk,latin,...}_hints_compute_edges' are the functions to find - * edges; they are specific to a script. - * - * - * A H - * | | - * | | - * | | - * | | - * C | | F - * +------<-----+ +-----<------+ - * | B G | - * | | - * | | - * +--------------->------------------+ - * D E - * - * - * Stems - * - * Segments need to be `linked' to other ones in order to detect stems. - * A stem is made of two segments that face each other in opposite - * directions and that are sufficiently close to each other. Using - * vocabulary from the TrueType specification, stem segments form a - * `black distance'. - * - * In the above ASCII drawing, the horizontal segments are BC, DE, and - * FG; the vertical segments are AB, CD, EF, and GH. - * - * Each segment has at most one `best' candidate to form a black - * distance, or no candidate at all. Notice that two distinct segments - * can have the same candidate, which frequently means a serif. - * - * A stem is recognized by the following condition: - * - * best segment_1 = segment_2 && best segment_2 = segment_1 - * - * The best candidate is stored in field `link' in structure - * `AF_Segment'. - * - * Stems are detected by `af_{cjk,latin,...}_hint_edges'. - * - * In the above ASCII drawing, the best candidate for both AB and CD is - * GH, while the best candidate for GH is AB. Similarly, the best - * candidate for EF and GH is AB, while the best candidate for AB is - * GH. - * - * - * Serifs - * - * On the opposite, a serif has - * - * best segment_1 = segment_2 && best segment_2 != segment_1 - * - * where segment_1 corresponds to the serif segment (CD and EF in the - * above ASCII drawing). - * - * The best candidate is stored in field `serif' in structure - * `AF_Segment' (and `link' is set to NULL). - * - * Serifs are detected by `af_{cjk,latin,...}_hint_edges'. - * - * - * Touched points - * - * A point is called `touched' if it has been processed somehow by the - * auto-hinter. It basically means that it shouldn't be moved again - * (or moved only under certain constraints to preserve the already - * applied processing). - * - * - * Flat and round segments - * - * Segments are `round' or `flat', depending on the series of points - * that define them. A segment is round if the next and previous point - * of an extremum (which can be either a single point or sequence of - * points) are both conic or cubic control points. Otherwise, a - * segment with an extremum is flat. - * - * - * Strong Points - * - * Experience has shown that points which are not part of an edge need - * to be interpolated linearly between their two closest edges, even if - * these are not part of the contour of those particular points. - * Typical candidates for this are - * - * - angle points (i.e., points where the `in' and `out' direction - * differ greatly) - * - * - inflection points (i.e., where the `in' and `out' angles are the - * same, but the curvature changes sign) - * - * `af_glyph_hints_align_strong_points' is the function which takes - * care of such situations; it is equivalent to the TrueType `IP' - * hinting instruction. - * - * - * Weak Points - * - * Other points in the outline must be interpolated using the - * coordinates of their previous and next unfitted contour neighbours. - * These are called `weak points' and are touched by the function - * `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP' - * hinting instruction. Typical candidates are control points and - * points on the contour without a major direction. - * - * The major effect is to reduce possible distortion caused by - * alignment of edges and strong points, thus weak points are processed - * after strong points. - */ - - - /* point hint flags */ - typedef enum AF_Flags_ - { - AF_FLAG_NONE = 0, - - /* point type flags */ - AF_FLAG_CONIC = 1 << 0, - AF_FLAG_CUBIC = 1 << 1, - AF_FLAG_CONTROL = AF_FLAG_CONIC | AF_FLAG_CUBIC, - - /* point extremum flags */ - AF_FLAG_EXTREMA_X = 1 << 2, - AF_FLAG_EXTREMA_Y = 1 << 3, - - /* point roundness flags */ - AF_FLAG_ROUND_X = 1 << 4, - AF_FLAG_ROUND_Y = 1 << 5, - - /* point touch flags */ - AF_FLAG_TOUCH_X = 1 << 6, - AF_FLAG_TOUCH_Y = 1 << 7, - - /* candidates for weak interpolation have this flag set */ - AF_FLAG_WEAK_INTERPOLATION = 1 << 8, - - /* all inflection points in the outline have this flag set */ - AF_FLAG_INFLECTION = 1 << 9 - - } AF_Flags;

To - support this I use the face_index argument of FT_(Open|New)_Face() - functions, and pretend the suitcase file is a collection. - - Warning: fbit and NFNT bitmap resources are not supported yet. In old - sfnt fonts, bitmap glyph data for each size is stored in each `NFNT' - resources instead of the `bdat' table in the sfnt resource. Therefore, - face->num_fixed_sizes is set to 0, because bitmap data in `NFNT' - resource is unavailable at present. - - The Mac FOND support works roughly like this: - - - Check whether the offered stream points to a Mac suitcase file. This - is done by checking the file type: it has to be 'FFIL' or 'tfil'. The - stream that gets passed to our init_face() routine is a stdio stream, - which isn't usable for us, since the FOND resources live in the - resource fork. So we just grab the stream->pathname field. - - - Read the FOND resource into memory, then check whether there is a - TrueType font and/or(!) a Type 1 font available. - - - If there is a Type 1 font available (as a separate `LWFN' file), read - its data into memory, massage it slightly so it becomes PFB data, wrap - it into a memory stream, load the Type 1 driver and delegate the rest - of the work to it by calling FT_Open_Face(). (XXX TODO: after this - has been done, the kerning data from the FOND resource should be - appended to the face: On the Mac there are usually no AFM files - available. However, this is tricky since we need to map Mac char - codes to ps glyph names to glyph ID's...) - - - If there is a TrueType font (an `sfnt' resource), read it into memory, - wrap it into a memory stream, load the TrueType driver and delegate - the rest of the work to it, by calling FT_Open_Face(). - - - Some suitcase fonts (notably Onyx) might point the `LWFN' file to - itself, even though it doesn't contains `POST' resources. To handle - this special case without opening the file an extra time, we just - ignore errors from the `LWFN' and fallback to the `sfnt' if both are - available. - */ - - -#include <ft2build.h> -#include FT_FREETYPE_H -#include FT_TRUETYPE_TAGS_H -#include FT_INTERNAL_STREAM_H -#include "ftbase.h" - - /* This is for Mac OS X.

The specification of the BDF font format is -available from Adobe's web site: - - http://partners.adobe.com/public/developer/en/font/5005.BDF_Spec.pdf - -Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org). -They do not define vertical metrics, because the X Consortium BDF -specification has removed them. - - -Encodings -********* - -The variety of encodings that accompanies bdf fonts appears to encompass the -small set defined in freetype.h. On the other hand, two properties that -specify encoding and registry are usually defined in bdf fonts. - -I decided to make these two properties directly accessible, leaving to the -client application the work of interpreting them. For instance: - - - #include FT_INTERNAL_BDF_TYPES_H - - FT_Face face; - BDF_Public_Face bdfface; - - - FT_New_Face( library, ..., &face ); - - bdfface = (BDF_Public_Face)face; - - if ( ( bdfface->charset_registry == "ISO10646" ) && - ( bdfface->charset_encoding == "1" ) ) - [..] - - -Thus the driver always exports `ft_encoding_none' as face->charmap.encoding. -FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong -value given as argument into the corresponding glyph number. - -If the two properties are not available, Adobe Standard Encoding should be -assumed. - - -Anti-Aliased Bitmaps -******************** - -The driver supports an extension to the BDF format as used in Mark Leisher's -xmbdfed bitmap font editor. Microsoft's SBIT tool expects bitmap fonts in -that format for adding anti-aliased them to TrueType fonts. It introduces a -fourth field to the `SIZE' keyword which gives the bpp value (bits per -pixel) of the glyph data in the font. Possible values are 1 (the default), -2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels). The -driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits -per pixel (using 4, 16, and 256 gray levels, respectively). - - -Known problems -************** - -- A font is entirely loaded into memory. Obviously, this is not the Right - Thing(TM). If you have big fonts I suggest you convert them into PCF - format (using the bdftopcf utility): the PCF font drive of FreeType can - perform incremental glyph loading. - -When I have some time, I will implement on-demand glyph parsing. - -- Except for encodings properties, client applications have no visibility of - the PCF_Face object. This means that applications cannot directly access - font tables and must trust FreeType. - -- Currently, glyph names are ignored. - - I plan to give full visibility of the BDF_Face object in an upcoming - revision of the driver, thus implementing also glyph names. - -- As I have never seen a BDF font that defines vertical metrics, vertical - metrics are (parsed and) discarded. If you own a BDF font that defines - vertical metrics, please let me know (I will implement them in 5-10 - minutes). - - -License -******* - -Copyright (C) 2001-2002 by Francesco Zappa Nardelli - -Permission is hereby granted, free of charge, to any person obtaining -a copy of this software and associated documentation files (the -"Software"), to deal in the Software without restriction, including -without limitation the rights to use, copy, modify, merge, publish, -distribute, sublicense, and/or sell copies of the Software, and to -permit persons to whom the Software is furnished to do so, subject to -the following conditions: - -The above copyright notice and this permission notice shall be -included in all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, -EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF -MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. -IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY -CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, -TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE -SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. - -*** Portions of the driver (that is, bdflib.c and bdf.h): - -Copyright 2000 Computing Research Labs, New Mexico State University -Copyright 2001-2002, 2011 Francesco Zappa Nardelli - -Permission is hereby granted, free of charge, to any person obtaining a -copy of this software and associated documentation files (the "Software"), -to deal in the Software without restriction, including without limitation -the rights to use, copy, modify, merge, publish, distribute, sublicense, -and/or sell copies of the Software, and to permit persons to whom the -Software is furnished to do so, subject to the following conditions: - -The above copyright notice and this permission notice shall be included in -all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

For more details see the file `src/cache/ftcbasic.c'. - * - * Client applications can extend FTC_GNode with their own FTC_GNode - * and FTC_Family sub-classes to implement more complex caches (e.g., - * handling automatic synthesis, like obliquing & emboldening, colored - * glyphs, etc.). - * - * See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and - * `ftcsbits.h', which both extend FTC_GCache with additional - * optimizations. - * - * A typical FTC_GCache implementation must provide at least the - * following: - * - * - FTC_GNode sub-class, e.g. MyNode, with relevant methods: - * my_node_new (must call FTC_GNode_Init) - * my_node_free (must call FTC_GNode_Done) - * my_node_compare (must call FTC_GNode_Compare) - * my_node_remove_faceid (must call ftc_gnode_unselect in case - * of match) - * - * - FTC_Family sub-class, e.g. MyFamily, with relevant methods: - * my_family_compare - * my_family_init - * my_family_reset (optional) - * my_family_done - * - * - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query - * data. - * - * - Constant structures for a FTC_GNodeClass. - * - * - MyCacheNew() can be implemented easily as a call to the convenience - * function FTC_GCache_New. - * - * - MyCacheLookup with a call to FTC_GCache_Lookup. This function will - * automatically: - * - * - Search for the corresponding family in the cache, or create - * a new one if necessary.

What is this ---------------- - - `gxvalid' is a module to validate TrueType GX tables: a collection of - additional tables in TrueType font which are used by `QuickDraw GX - Text', Apple Advanced Typography (AAT). In addition, gxvalid can - validates `kern' tables which have been extended for AAT. Like the - otvalid module, gxvalid uses Freetype 2's validator framework - (ftvalid). - - You can link gxvalid with your program; before running your own layout - engine, gxvalid validates a font file. As the result, you can remove - error-checking code from the layout engine. It is also possible to - use gxvalid as a stand-alone font validator; the `ftvalid' test - program included in the ft2demo bundle calls gxvalid internally. - A stand-alone font validator may be useful for font developers. - - This documents documents the following issues. - - - supported TrueType GX tables - - fundamental validation limitations - - permissive error handling of broken GX tables - - `kern' table issue. - - -2. Supported tables -------------------- - - The following GX tables are currently supported. - - bsln - feat - just - kern(*) - lcar - mort - morx - opbd - prop - trak - - The following GX tables are currently unsupported. - - cvar - fdsc - fmtx - fvar - gvar - Zapf - - The following GX tables won't be supported. - - acnt(**) - hsty(***) - - The following undocumented tables in TrueType fonts designed for Apple - platform aren't handled either. - - addg - CVTM - TPNM - umif - - - *) The `kern' validator handles both the classic and the new kern - formats; the former is supported on both Microsoft and Apple - platforms, while the latter is supported on Apple platforms. - - **) `acnt' tables are not supported by currently available Apple font - tools. - - ***) There is one more Apple extension, `hsty', but it is for - Newton-OS, not GX (Newton-OS is a platform by Apple, but it can - use sfnt- housed bitmap fonts only). Therefore, it should be - excluded from `Apple platform' in the context of TrueType. - gxvalid ignores it as Apple font tools do so. - - - We have checked 183 fonts bundled with MacOS 9.1, MacOS 9.2, MacOS - 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. In addition, - we have checked 67 Dynalab fonts (designed for MacOS) and 189 Ricoh - fonts (designed for Windows and MacOS dual platforms). The number of - fonts including TrueType GX tables are as follows. - - bsln: 76 - feat: 191 - just: 84 - kern: 59 - lcar: 4 - mort: 326 - morx: 19 - opbd: 4 - prop: 114 - trak: 16 - - Dynalab and Ricoh fonts don't have GX tables except of `feat' and - `mort'. - - -3. Fundamental validation limitations -------------------------------------- - - TrueType GX provides layout information to libraries for font - rasterizers and text layout. gxvalid can check whether the layout - data in a font is conformant to the TrueType GX format specified by - Apple. But gxvalid cannot check a how QuickDraw GX/AAT renderer uses - the stored information. - - 3-1. Validation of State Machine activity - ----------------------------------------- - - QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout - features, and TrueType GX stores the state transition diagram of - this `State Machine' in a `StateTable' data structure. While the - State Machine receives a series of glyph IDs, the State Machine - starts with `start of text' state, walks around various states and - generates various layout information to the renderer, and finally - reaches the `end of text' state. - - gxvalid can check essential errors like: - - - possibility of state transitions to undefined states - - existence of glyph IDs that the State Machine doesn't know how - to handle - - the State Machine cannot compute the layout information from - given diagram - - These errors can be checked within finite steps, and without the - State Machine itself, because these are `expression' errors of state - transition diagram. - - There is no limitation about how long the State Machine walks - around, so validation of the algorithm in the state transition - diagram requires infinite steps, even if we had a State Machine in - gxvalid. Therefore, the following errors and problems cannot be - checked. - - - existence of states which the State Machine never transits to - - the possibility that the State Machine never reaches `end of - text' - - the possibility of stack underflow/overflow in the State Machine - (in ligature and contextual glyph substitutions, the State - Machine can store 16 glyphs onto its stack) - - In addition, gxvalid doesn't check `temporary glyph IDs' used in the - chained State Machines (in `mort' and `morx' tables). If a layout - feature is implemented by a single State Machine, a glyph ID - converted by the State Machine is passed to the glyph renderer, thus - it should not point to an undefined glyph ID. But if a layout - feature is implemented by chained State Machines, a component State - Machine (if it is not the final one) is permitted to generate - undefined glyph IDs for temporary use, because it is handled by next - component State Machine and not by the glyph renderer. To validate - such temporary glyph IDs, gxvalid must stack all undefined glyph IDs - which can occur in the output of the previous State Machine and - search them in the `ClassTable' structure of the current State - Machine. It is too complex to list all possible glyph IDs from the - StateTable, especially from a ligature substitution table. - - 3-2. Validation of relationship between multiple layout features - ---------------------------------------------------------------- - - gxvalid does not validate the relationship between multiple layout - features at all. - - If multiple layout features are defined in TrueType GX tables, - possible interactions, overrides, and conflicts between layout - features are implicitly given in the font too. For example, there - are several predefined spacing control features: - - - Text Spacing (Proportional/Monospace/Half-width/Normal) - - Number Spacing (Monospaced-numbers/Proportional-numbers) - - Kana Spacing (Full-width/Proportional) - - Ideographic Spacing (Full-width/Proportional) - - CJK Roman Spacing (Half-width/Proportional/Default-roman - /Full-width-roman/Proportional) - - If all layout features are independently managed, we can activate - inconsistent typographic rules like `Text Spacing=Monospace' and - `Ideographic Spacing=Proportional' at the same time. - - The combinations of layout features is managed by a 32bit integer - (one bit each for selector setting), so we can define relationships - between up to 32 features, theoretically. But if one feature - setting affects another feature setting, we need typographic - priority rules to validate the relationship. Unfortunately, the - TrueType GX format specification does not give such information even - for predefined features. - - -4. Permissive error handling of broken GX tables ------------------------------------------------- - - When Apple's font rendering system finds an inconsistency, like a - specification violation or an unspecified value in a TrueType GX - table, it does not always return error. In most cases, the rendering - engine silently ignores such wrong values or even whole tables. In - fact, MacOS is shipped with fonts including broken GX/AAT tables, but - no harmful effects due to `officially broken' fonts are observed by - end-users. - - gxvalid is designed to continue the validation process as long as - possible. When gxvalid find wrong values, gxvalid warns it at least, - and takes a fallback procedure if possible. The fallback procedure - depends on the debug level. - - We used the following three tools to investigate Apple's error handling. - - - FontValidator (for MacOS 8.5 - 9.2) resource fork font - - ftxvalidator (for MacOS X 10.1 -) dfont or naked-sfnt - - ftxdumperfuser (for MacOS X 10.1 -) dfont or naked-sfnt - - However, all tests were done on a PowerPC based Macintosh; at present, - we have not checked those tools on a m68k-based Macintosh. - - In total, we checked 183 fonts bundled to MacOS 9.1, MacOS 9.2, MacOS - 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. These fonts - are distributed officially, but many broken GX/AAT tables were found - by Apple's font tools. In the following, we list typical violation of - the GX specification, in fonts officially distributed with those Apple - systems. - - 4-1. broken BinSrchHeader (19/183) - ---------------------------------- - - `BinSrchHeader' is a header of a data array for m68k platforms to - access memory efficiently. Although there are only two independent - parameters for real (`unitSize' and `nUnits'), BinSrchHeader has - three additional parameters which can be calculated from `unitSize' - and `nUnits', for fast setup. Apple font tools ignore them - silently, so gxvalid warns if it finds and inconsistency, and always - continues validation. The additional parameters are ignored - regardless of the consistency. - - 19 fonts include such inconsistencies; all breaks are in the - BinSrchHeader structure of the `kern' table. - - 4-2. too-short LookupTable (5/183) - ---------------------------------- - - LookupTable format 0 is a simple array to get a value from a given - GID (glyph ID); the index of this array is a GID too. Therefore, - the length of the array is expected to be same as the maximum GID - value defined in the `maxp' table, but there are some fonts whose - LookupTable format 0 is too short to cover all GIDs. FontValidator - ignores this error silently, ftxvalidator and ftxdumperfuser both - warn and continue. Similar problems are found in format 3 subtables - of `kern'. gxvalid warns always and abort if the validation level - is set to FT_VALIDATE_PARANOID. - - 5 fonts include too-short kern format 0 subtables. - 1 font includes too-short kern format 3 subtable. - - 4-3. broken LookupTable format 2 (1/183) - ---------------------------------------- - - LookupTable format 2, subformat 4 covers the GID space by a - collection of segments which are specified by `firstGlyph' and - `lastGlyph'. Some fonts store `firstGlyph' and `lastGlyph' in - reverse order, so the segment specification is broken. Apple font - tools ignore this error silently; a broken segment is ignored as if - it did not exist. gxvalid warns and normalize the segment at - FT_VALIDATE_DEFAULT, or ignore the segment at FT_VALIDATE_TIGHT, or - abort at FT_VALIDATE_PARANOID. - - 1 font includes broken LookupTable format 2, in the `just' table. - - *) It seems that all fonts manufactured by ITC for AppleWorks have - this error. - - 4-4. bad bracketing in glyph property (14/183) - ---------------------------------------------- - - GX/AAT defines a `bracketing' property of the glyphs in the `prop' - table, to control layout features of strings enclosed inside and - outside of brackets. Some fonts give inappropriate bracket - properties to glyphs. Apple font tools warn about this error; - gxvalid warns too and aborts at FT_VALIDATE_PARANOID. - - 14 fonts include wrong bracket properties. - - - 4-5. invalid feature number (117/183) - ------------------------------------- - - The GX/AAT extension can include 255 different layout features, but - popular layout features are predefined (see - http://developer.apple.com/fonts/Registry/index.html). Some fonts - include feature numbers which are incompatible with the predefined - feature registry. - - In our survey, there are 140 fonts including `feat' table. - - a) 67 fonts use a feature number which should not be used. - b) 117 fonts set the wrong feature range (nSetting). This is mostly - found in the `mort' and `morx' tables. - - Apple font tools give no warning, although they cannot recognize - what the feature is. At FT_VALIDATE_DEFAULT, gxvalid warns but - continues in both cases (a, b). At FT_VALIDATE_TIGHT, gxvalid warns - and aborts for (a), but continues for (b). At FT_VALIDATE_PARANOID, - gxvalid warns and aborts in both cases (a, b). - - 4-6. invalid prop version (10/183) - ---------------------------------- - - As most TrueType GX tables, the `prop' table must start with a 32bit - version identifier: 0x00010000, 0x00020000 or 0x00030000. But some - fonts store nonsense binary data instead. When Apple font tools - find them, they abort the processing immediately, and the data which - follows is unhandled. gxvalid does the same. - - 10 fonts include broken `prop' version. - - All of these fonts are classic TrueType fonts for the Japanese - script, manufactured by Apple. - - 4-7. unknown resource name (2/183) - ------------------------------------ - - NOTE: THIS IS NOT A TRUETYPE GX ERROR. - - If a TrueType font is stored in the resource fork or in dfont - format, the data must be tagged as `sfnt' in the resource fork index - to invoke TrueType font handler for the data. But the TrueType font - data in `Keyboard.dfont' is tagged as `kbd', and that in - `LastResort.dfont' is tagged as `lst'. Apple font tools can detect - that the data is in TrueType format and successfully validate them. - Maybe this is possible because they are known to be dfont. The - current implementation of the resource fork driver of FreeType - cannot do that, thus gxvalid cannot validate them. - - 2 fonts use an unknown tag for the TrueType font resource. - -5. `kern' table issues ----------------------- - - In common terminology of TrueType, `kern' is classified as a basic and - platform-independent table. But there are Apple extensions of `kern', - and there is an extension which requires a GX state machine for - contextual kerning. Therefore, gxvalid includes a special validator - for `kern' tables. Unfortunately, there is no exact algorithm to - check Apple's extension, so gxvalid includes a heuristic algorithm to - find the proper validation routines for all possible data formats, - including the data format for Microsoft. By calling - classic_kern_validate() instead of gxv_validate(), you can specify the - `kern' format explicitly. However, current FreeType2 uses Microsoft - `kern' format only, others are ignored (and should be handled in a - library one level higher than FreeType). - - 5-1. History - ------------ - - The original 16bit version of `kern' was designed by Apple in the - pre-GX era, and it was also approved by Microsoft. Afterwards, - Apple designed a new 32bit version of the `kern' table. According - to the documentation, the difference between the 16bit and 32bit - version is only the size of variables in the `kern' header. In the - following, we call the original 16bit version as `classic', and - 32bit version as `new'. - - 5-2. Versions and dialects which should be differentiated - --------------------------------------------------------- - - The `kern' table consists of a table header and several subtables. - The version number which identifies a `classic' or a `new' version - is explicitly written in the table header, but there are - undocumented differences between Microsoft's and Apple's formats. - It is called a `dialect' in the following. There are three cases - which should be handled: the new Apple-dialect, the classic - Apple-dialect, and the classic Microsoft-dialect. An analysis of - the formats and the auto detection algorithm of gxvalid is described - in the following. - - 5-2-1. Version detection: classic and new kern - ---------------------------------------------- - - According to Apple TrueType specification, there are only two - differences between the classic and the new: - - - The `kern' table header starts with the version number. - The classic version starts with 0x0000 (16bit), - the new version starts with 0x00010000 (32bit). - - - In the `kern' table header, the number of subtables follows - the version number. - In the classic version, it is stored as a 16bit value. - In the new version, it is stored as a 32bit value. - - From Apple font tool's output (DumpKERN is also tested in addition - to the three Apple font tools in above), there is another - undocumented difference. In the new version, the subtable header - includes a 16bit variable named `tupleIndex' which does not exist - in the classic version. - - The new version can store all subtable formats (0, 1, 2, and 3), - but the Apple TrueType specification does not mention the subtable - formats available in the classic version. - - 5-2-2. Available subtable formats in classic version - ---------------------------------------------------- - - Although the Apple TrueType specification recommends to use the - classic version in the case if the font is designed for both the - Apple and Microsoft platforms, it does not document the available - subtable formats in the classic version. - - According to the Microsoft TrueType specification, the subtable - format assured for Windows and OS/2 support is only subtable - format 0. The Microsoft TrueType specification also describes - subtable format 2, but does not mention which platforms support - it. Aubtable formats 1, 3, and higher are documented as reserved - for future use. Therefore, the classic version can store subtable - formats 0 and 2, at least. `ttfdump.exe', a font tool provided by - Microsoft, ignores the subtable format written in the subtable - header, and parses the table as if all subtables are in format 0. - - `kern' subtable format 1 uses a StateTable, so it cannot be - utilized without a GX State Machine. Therefore, it is reasonable - to assume that format 1 (and 3) were introduced after Apple had - introduced GX and moved to the new 32bit version. - - 5-2-3. Apple and Microsoft dialects - ----------------------------------- - - The `kern' subtable has a 16bit `coverage' field to describe - kerning attributes, but bit interpretations by Apple and Microsoft - are different: For example, Apple uses bits 0-7 to identify the - subtable, while Microsoft uses bits 8-15. - - In addition, due to the output of DumpKERN and FontValidator, - Apple's bit interpretations of coverage in classic and new version - are incompatible also. In summary, there are three dialects: - classic Apple dialect, classic Microsoft dialect, and new Apple - dialect. The classic Microsoft dialect and the new Apple dialect - are documented by each vendors' TrueType font specification, but - the documentation for classic Apple dialect is not available. - - For example, in the new Apple dialect, bit 15 is documented as - `set to 1 if the kerning is vertical'. On the other hand, in - classic Microsoft dialect, bit 1 is documented as `set to 1 if the - kerning is horizontal'. From the outputs of DumpKERN and - FontValidator, classic Apple dialect recognizes 15 as `set to 1 - when the kerning is horizontal'. From the results of similar - experiments, classic Apple dialect seems to be the Endian reverse - of the classic Microsoft dialect. - - As a conclusion it must be noted that no font tool can identify - classic Apple dialect or classic Microsoft dialect automatically. - - 5-2-4. gxvalid auto dialect detection algorithm - ----------------------------------------------- - - The first 16 bits of the `kern' table are enough to identify the - version: - - - if the first 16 bits are 0x0000, the `kern' table is in - classic Apple dialect or classic Microsoft dialect - - if the first 16 bits are 0x0001, and next 16 bits are 0x0000, - the kern table is in new Apple dialect. - - If the `kern' table is a classic one, the 16bit `coverage' field - is checked next. Firstly, the coverage bits are decoded for the - classic Apple dialect using the following bit masks (this is based - on DumpKERN output): - - 0x8000: 1=horizontal, 0=vertical - 0x4000: not used - 0x2000: 1=cross-stream, 0=normal - 0x1FF0: reserved - 0x000F: subtable format - - If any of reserved bits are set or the subtable bits is - interpreted as format 1 or 3, we take it as `impossible in classic - Apple dialect' and retry, using the classic Microsoft dialect. - - The most popular coverage in new Apple-dialect: 0x8000, - The most popular coverage in classic Apple-dialect: 0x0000, - The most popular coverage in classic Microsoft dialect: 0x0001. - - 5-3. Tested fonts - ----------------- - - We checked 59 fonts bundled with MacOS and 38 fonts bundled with - Windows, where all font include a `kern' table. - - - fonts bundled with MacOS - * new Apple dialect - format 0: 18 - format 2: 1 - format 3: 1 - * classic Apple dialect - format 0: 14 - * classic Microsoft dialect - format 0: 15 - - - fonts bundled with Windows - * classic Microsoft dialect - format 0: 38 - - It looks strange that classic Microsoft-dialect fonts are bundled to - MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont. - - - ACKNOWLEDGEMENT - --------------- - - Some parts of gxvalid are derived from both the `gxlayout' module and - the `otvalid' module. Development of gxlayout was supported by the - Information-technology Promotion Agency(IPA), Japan. - - The detailed analysis of undefined glyph ID utilization in `mort' and - `morx' tables is provided by George Williams. - ------------------------------------------------------------------------- - -Copyright 2004, 2005, 2007 by -suzuki toshiya, Masatake YAMATO, Red hat K.K., -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.

(Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12.

Subsequent tables are also less than or equal to - those sizes. These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each.

If not all input can be processed (because there is not - enough room in the output buffer), next_in is updated and processing - will resume at this point for the next call of inflate(). - - - Provide more output starting at next_out and update next_out and avail_out - accordingly. inflate() provides as much output as possible, until there - is no more input data or no more space in the output buffer (see below - about the flush parameter). - - Before the call of inflate(), the application should ensure that at least - one of the actions is possible, by providing more input and/or consuming - more output, and updating the next_* and avail_* values accordingly. - The application can consume the uncompressed output when it wants, for - example when the output buffer is full (avail_out == 0), or after each - call of inflate(). If inflate returns Z_OK and with zero avail_out, it - must be called again after making room in the output buffer because there - might be more output pending. - - If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much - output as possible to the output buffer. The flushing behavior of inflate is - not specified for values of the flush parameter other than Z_SYNC_FLUSH - and Z_FINISH, but the current implementation actually flushes as much output - as possible anyway. - - inflate() should normally be called until it returns Z_STREAM_END or an - error. However if all decompression is to be performed in a single step - (a single call of inflate), the parameter flush should be set to - Z_FINISH. In this case all pending input is processed and all pending - output is flushed; avail_out must be large enough to hold all the - uncompressed data. (The size of the uncompressed data may have been saved - by the compressor for this purpose.) The next operation on this stream must - be inflateEnd to deallocate the decompression state. The use of Z_FINISH - is never required, but can be used to inform inflate that a faster routine - may be used for the single inflate() call. - - If a preset dictionary is needed at this point (see inflateSetDictionary - below), inflate sets strm-adler to the adler32 checksum of the - dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise - it sets strm->adler to the adler32 checksum of all output produced - so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or - an error code as described below. At the end of the stream, inflate() - checks that its computed adler32 checksum is equal to that saved by the - compressor and returns Z_STREAM_END only if the checksum is correct. - - inflate() returns Z_OK if some progress has been made (more input processed - or more output produced), Z_STREAM_END if the end of the compressed data has - been reached and all uncompressed output has been produced, Z_NEED_DICT if a - preset dictionary is needed at this point, Z_DATA_ERROR if the input data was - corrupted (input stream not conforming to the zlib format or incorrect - adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent - (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not - enough memory, Z_BUF_ERROR if no progress is possible or if there was not - enough room in the output buffer when Z_FINISH is used.

In both -cases the compiler was gcc. When back in Paris, I will test it also -on linux/alpha. - - -Encodings -********* - -Use `FT_Get_BDF_Charset_ID' to access the encoding and registry. - -The driver always exports `ft_encoding_none' as face->charmap.encoding. -FT_Get_Char_Index() behavior is unmodified, that is, it converts the ULong -value given as argument into the corresponding glyph number. - - -Known problems -************** - -- dealing explicitly with encodings breaks the uniformity of freetype2 - api. - -- except for encodings properties, client applications have no - visibility of the PCF_Face object.
