IMPORTANT BUG FIXES + + - Very unfortunately, FreeType 2.3.8 contained a change that broke + its official ABI. The end result is that programs compiled + against previous versions of the library, but dynamically linked + to 2.3.8 can experience memory corruption if they call the + `FT_Get_PS_Font_Info' function. + + We recommend all users to upgrade to 2.3.9 as soon as possible, + or to downgrade to a previous release of the library if this is + not an option. + + The origin of the bug is that a new field was added to the + publicly defined `PS_FontInfoRec' structure. Unfortunately, + objects of this type can be stack or heap allocated by callers + of `FT_Get_PS_Font_Info', resulting in a memory buffer + overwrite with its implementation in 2.3.8. + + If you want to know whether your code is vulnerable to this + issue, simply search for the substrings `PS_FontInfo' and + `PS_Font_Info' in your source code. If none is found, your code + is safe and is not affected. + + The FreeType team apologizes for the problem. + + - The POSIX support of MacOS resource-fork fonts (Suitcase fonts + and LaserWriter Type1 PostScript fonts) was broken in 2.3.8. If + FreeType2 is built without Carbon framework, these fonts are not + handled correctly. Version 2.3.7 didn't have this bug. + + - `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for + almost all font formats except TrueType fonts. + + - Fix a bug in the SFNT kerning table loader/parser which could + crash the engine if certain malformed tables were encountered. + + - Composite SFNT bitmaps are now handled correctly. + + + II. IMPORTANT CHANGES + + - The new functions `FT_Get_CID_Is_Internally_CID_keyed' and + `FT_Get_CID_From_Glyph_Index' can be used to access CID-keyed + CFF fonts via CID values. This code has been contributed by + Michael Toftdal. + + + III. MISCELLANEOUS + + - `FT_Outline_Get_InsideBorder' returns FT_STROKER_BORDER_RIGHT + for empty outlines. This was incorrectly documented. + + - The `ftview' demo program now supports UTF-8 encoded strings. + + +====================================================================== + +CHANGES BETWEEN 2.3.8 and 2.3.7 + + I. IMPORTANT BUG FIXES + + - CID-keyed fonts in an SFNT wrapper were not handled correctly. + + - The smooth renderer produced truncated images (on the right) for + outline parts with negative horizontal values. Most fonts don't + contain outlines left to the y coordinate axis, but the effect + was very noticeable for outlines processed with FT_Glyph_Stroke, + using thick strokes. + + - `FT_Get_TrueType_Engine_Type' returned a wrong value if both + configuration macros TT_CONFIG_OPTION_BYTECODE_INTERPRETER and + TT_CONFIG_OPTION_UNPATENTED_HINTING were defined. + + - The `face_index' field in the `FT_Face' structure wasn't + initialized properly after calling FT_Open_Face and friends with + a positive face index for CFFs, WinFNTs, and, most importantly, + for TrueType Collections (TTCs). + + + II. IMPORTANT CHANGES + + - Rudimentary support for Type 1 fonts and CID-keyed Type 1 fonts + in an SFNT wrapper has been added -- such fonts are used on the + Mac. The core SFNT tables `TYP1' and `CID ' are passed to the + PS Type 1 and CID-keyed PS font drivers; other tables (`ALMX', + `BBOX', etc.) are not supported yet. + + - A new interface to extract advance values of glyphs without + loading their outlines has been added. The functions are called + `FT_Get_Advance' and `FT_Get_Advances'; they are defined in file + `ftadvanc.h' (to be accessed as FT_ADVANCES_H). + + - A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been + contributed by David Bevan to access the embedding and + subsetting restriction information of fonts. + + + III. MISCELLANEOUS + + - FT_MulFix is now an inlined function; by default, assembler code + is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX + and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more. + + - The handling of `tricky' fonts (this is, fonts which don't work + with the autohinter, needing the font format's hinting engine) + has been generalized and changed slightly: + + . A new face flag FT_FACE_FLAG_TRICKY indicates that the font + format's hinting engine is necessary for correct rendering. + The macro FT_IS_TRICKY can be used to check this flag. + + . FT_LOAD_NO_HINTING is now ignored for tricky fonts. To really + force raw loading of such fonts (without hinting), both + FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used -- + this is something which you probably never want to do. + + . Tricky TrueType fonts always use the bytecode interpreter, + either the patented or unpatented version. + + - The function `FT_GlyphSlot_Own_Bitmap' has been moved from + FT_SYNTHESIS_H to FT_BITMAP_H; it is now part of the `official' + API. (The functions in FT_SYNTHESIS_H are still subject to + change, however.) + + - In the `ftdiff' demo program you can now toggle the use of + FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'. + + +====================================================================== + +CHANGES BETWEEN 2.3.7 and 2.3.6 + + I. IMPORTANT BUG FIXES + + - If the library was compiled on an i386 platform using gcc, and + compiler option -O3 was given, `FT_MulFix' sometimes returned + incorrect results which could have caused problems with + `FT_Request_Metrics' and `FT_Select_Metrics', returning an + incorrect descender size. + + - Pure CFFs without subfonts were scaled incorrectly if the font + matrix was non-standard. This bug has been introduced in + version 2.3.6. + + - The `style_name' field in the `FT_FaceRec' structure often + contained a wrong value for Type 1 fonts. This misbehaviour + has been introduced in version 2.3.6 while trying to fix + another problem. [Note, however, that this value is + informative only since the used algorithm to extract it is + very simplistic.] + + + II. IMPORTANT CHANGES + + - Two new macros, FT_OUTLINE_SMART_DROPOUTS and + FT_OUTLINE_EXCLUDE_STUBS, have been introduced. Together with + FT_OUTLINE_IGNORE_DROPOUTS (which was ignored previously) it is + now possible to control the dropout mode of the `raster' module + (for B&W rasterization), using the `flags' field in the + `FT_Outline' structure. + + - The TrueType bytecode interpreter now passes the dropout mode to + the B&W rasterizer. This greatly increases the output for small + ppem values of many fonts like `pala.ttf'. + + +====================================================================== + +CHANGES BETWEEN 2.3.6 and 2.3.5 + + I. IMPORTANT BUG FIXES + + - A bunch of potential security problems have been found. All + users should update. + + - Microsoft Unicode cmaps in TrueType fonts are now always + preferred over Apple cmaps. This is not a bug per se, but there + exist some buggy fonts created for MS which have broken Apple + cmaps. This affects only the automatic selection of FreeType; + it's always possible to manually select an Apple Unicode cmap if + desired. + + - Many bug fixes to the TrueType bytecode interpreter. + + - Improved Mac support. + + - Subsetted CID-keyed CFFs are now supported correctly. + + - CID-keyed CFFs with subfonts which are scaled in a non-standard + way are now handled correctly. + + - A call to FT_Open_Face with `face_index' < 0 crashed FreeType if + the font was a Windows (bitmap) FNT/FON. + + + II. IMPORTANT CHANGES + + - The new function `FT_Get_CID_Registry_Ordering_Supplement' gives + access to those fields in a CID-keyed font. The code has been + contributed by Derek Clegg. + + - George Williams contributed code to validate the new `MATH' + OpenType table (within the `otvalid' module). The `ftvalid' + demo program has been extended accordingly. + + - An API for cmap 14 support (for Unicode Variant Selectors, UVS) + has been contributed by George Williams. + + - A new face flag FT_FACE_FLAG_CID_KEYED has been added, together + with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is + CID-keyed. + + + III. MISCELLANEOUS + + - Build support for symbian has been contributed. + + - Better WGL4 glyph name support, contributed by Sergey Tolstov. + + - Debugging output of the various FT_TRACEX macros is now sent to + stderr. + + - The `ftview' demo program now provides artificial slanting too. + + - The `ftvalid' demo program has a new option `-f' to select the + font index. + + +====================================================================== + +CHANGES BETWEEN 2.3.5 and 2.3.4 + + I. IMPORTANT BUG FIXES + + - Some subglyphs in TrueType fonts were handled incorrectly due to + a missing graphics state reinitialization. + + - Large .Z files (as distributed with some X11 packages) weren't + handled correctly, making FreeType increase the heap stack in an + endless loop. + + - A large number of bugs have been fixed to avoid crashes and + endless loops with invalid fonts. + + + II. IMPORTANT CHANGES + + - The two new cache functions `FTC_ImageCache_LookupScaler' and + `FTC_SBit_Cache_LookupScaler' have been added to allow lookup of + glyphs using an `FTC_Scaler' object; this makes it possible to + use fractional pixel sizes in the cache. The demo programs have + been updated accordingly to use this feature. + + - A new API `FT_Get_CMap_Format' has been added to get the cmap + format of a TrueType font. This is useful in handling PDF + files. The code has been contributed by Derek Clegg. + + - The auto-hinter now produces better output by default for + non-Latin scripts like Indic. This was done by using the CJK + hinting module as the default instead of the Latin one. Thanks + to Rahul Bhalerao for this suggestion. + + - A new API `FT_Face_CheckTrueTypePatents' has been added to find + out whether a given TrueType font uses patented bytecode + instructions. The `ft2demos' bundle contains a new program + called `ftpatchk' which demonstrates its usage. + + - A new API `FT_Face_SetUnpatentedHinting' has been added to + enable or disable the unpatented hinter. + + - Support for Windows FON files in PE format has been contributed + by Dmitry Timoshkov. + + + III. MISCELLANEOUS + + - Vincent Richomme contributed Visual C++ project files for Pocket + PCs. + + +====================================================================== + +CHANGES BETWEEN 2.3.4 and 2.3.3 + + I. IMPORTANT BUG FIXES + + - A serious bug in the handling of bitmap fonts (and bitmap + strikes of outline fonts) has been introduced in 2.3.3. + + +====================================================================== + +CHANGES BETWEEN 2.3.3 and 2.3.2 + + I. IMPORTANT BUG FIXES + + - Remove a serious regression in the TrueType bytecode interpreter + that was introduced in version 2.3.2. Note that this does not + disable the improvements introduced to the interpreter in + version 2.3.2, only some ill cases that occurred with certain + fonts (though a few popular ones). + + - The auto-hinter now ignores single-point contours for computing + blue zones. This bug created `wavy' baselines when rendering + text with various fonts that use these contours to model + mark-attach points (these are points that are never rasterized + and are placed outside of the glyph's real outline). + + - The `rsb_delta' and `lsb_delta' glyph slot fields are now set to + zero for mono-spaced fonts. Otherwise code that uses them would + essentially ruin the fixed-advance property. + + - Fix CVE-2007-1351 which can cause an integer overflow while + parsing BDF fonts, leading to a potentially exploitable heap + overflow condition. + + + II. MISCELLANEOUS + + - Fixed compilation issues on some 64-bit platforms (see ChangeLog + for details). + + - A new demo program `ftdiff' has been added to compare TrueType + hinting, FreeType's auto hinting, and rendering without hinting + in three columns. + + +====================================================================== + +CHANGES BETWEEN 2.3.2 and 2.3.1 + + I. IMPORTANT BUG FIXES + + - FreeType returned incorrect kerning information from TrueType + fonts when the bytecode interpreter was enabled. This happened + due to a typo introduced in version 2.3.0. + + - Negative kerning values from PFM files are now reported + correctly (they were read as 16-bit unsigned values from the + file). + + - Fixed a small memory leak when `FT_Init_FreeType' failed for + some reason. + + - The Postscript hinter placed and sized very thin and ghost stems + incorrectly. + + - The TrueType bytecode interpreter has been fixed to get rid of + most of the rare differences seen in comparison to the Windows + font loader. + + + II. IMPORTANT CHANGES + + - The auto-hinter now better deals with serifs and corner cases + (e.g., glyph '9' in Arial at 9pt, 96dpi). It also improves + spacing adjustments and doesn't change widths for non-spacing + glyphs. + + - Many Mac-specific functions are deprecated (but still + available); modern replacements have been provided for them. + See the documentation in file `ftmac.h'. + + +====================================================================== + +CHANGES BETWEEN 2.3.1 and 2.3.0 + + I. IMPORTANT BUG FIXES + + - The TrueType interpreter sometimes returned incorrect horizontal + metrics due to a bug in the handling of the SHZ instruction. + + - A typo in a security check introduced after version 2.2.1 + prevented FreeType to render some glyphs in CFF fonts. + + +====================================================================== + +CHANGES BETWEEN 2.3.0 and 2.2.1 + + I. IMPORTANT BUG FIXES + + - The PCF font loader is now much more robust while loading + malformed font files. + + - Various memory leaks have been found and fixed. + + - The TrueType name loader now deals properly with some fonts that + encode their names in UTF-16 (the specification was vague, and + the code incorrectly assumed UCS-4). + + - Fixed the TrueType bytecode loader to deal properly with subtle + monochrome/gray issues when scaling the CVT. Some fonts + exhibited bad rendering artifacts otherwise. + + - `FT_GlyphSlot_Embolden' now supports vertical layouts correctly + (it mangled the vertical advance height). + + - Fixed byte endian issues of `ftmac.c' to support Mac OS X on + i386. + + - The PFR font loader no longer erroneously tags font files + without any outlines as FT_FACE_FLAG_SCALABLE. + + + II. NEW API FUNCTIONS + + - `FT_Library_SetLcdFilter' allows you to select a special filter + to be applied to the bitmaps generated by `FT_Render_Glyph' if + one of the FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V modes has + been selected. This filter is used to reduce color fringes; + several settings are available through the FT_LCD_FILTER_XXX + enumeration. + + Its declaration and documentation can be found in file + `include/freetype/ftlcdfil.h' (to be accessed with macro + FT_LCD_FILTER_H). + + *IMPORTANT*: This function returns an error + (FT_Err_Unimplemented_Feature) in default builds of the library + for patent reasons. See below. + + - `FT_Get_Gasp' allows you to query the flags of the TrueType + `gasp' table for a given character pixel size. This is useful + to duplicate the text rendering of MS Windows when the native + bytecode interpreter is enabled (which isn't the default for + other patent reasons). + + Its declaration and documentation can be found in file + `include/freetype/ftgasp.h' (to be accessed with macro + FT_GASP_H). + + + III. IMPORTANT CHANGES + + - The auto-hinter has been tuned a lot to improve its results with + serif fonts, resulting in much better font rendering of many web + pages. + + - The unpatented hinter is now part of the default build of the + library; we have added code to automatically support `tricky' + fonts that need it. + + This means that FreeType should `just work' with certain Asian + fonts, like MingLiU, which cannot properly be loaded without a + bytecode interpreter, but which fortunately do not use any of + the patented bytecode opcodes. We detect these fonts by name, + so please report any font file that doesn't seem to work with + FreeType, and we shall do what we can to support it in a next + release. + + Note that the API hasn't changed, so you can still force + unpatented hinting with a special parameter to `FT_Open_Face' as + well. This might be useful in same cases; for example, a PDF + reader might present a user option to activate it to deal with + certain `tricky' embedded fonts which cannot be clearly + identified. + + If you are a developer for embedded systems, you might want to + *disable* the feature to save code space by undefining + TT_CONFIG_OPTION_UNPATENTED_HINTING in file `ftoption.h'. + + - LCD-optimized rendering is now *disabled* in all default builds + of the library, mainly due to patent issues. For more + information see: + + http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html + + A new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING + has been introduced in `ftoption.h'; manually define it in this + file if you want to re-enable the feature. + + The change only affects the implementation, not the FreeType + API. This means that clients don't need to be modified, because + the library still generates LCD decimated bitmaps, but with the + added constraint that R=G=B on each triplet. + + The displayed result should be equal to normal anti-aliased + rendering. + + Additionally, if FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not + defined, the new `FT_Library_SetLcdFilter' function returns the + FT_Err_Unimplemented_Feature error code. + + - Some computation bugs in the TrueType bytecode interpreter were + found, which allow us to get rid of very subtle and rare + differences we had experienced with the Windows renderer. + + - It is now possible to cross-compile the library easily. See the + file `docs/INSTALL.CROSS' for details. + + - The file `src/base/ftmac.c' now contains code for Mac OS X only; + its deprecated function `FT_GetFile_From_Mac_Font_Name' always + returns an error even if the QuickDraw framework is available. + The previous version has been moved to `builds/mac/ftmac.c'. + + Selecting configure option `--with-quickdraw-carbon' makes the + build process use the original `ftmac.c' file instead of the Mac + OS X-only version. + + + IV. MISCELLANEOUS + + - Various performance and memory footprint optimizations have been + performed on the TrueType and CFF font loaders, sometimes with + very drastic benefits (e.g., the TrueType loader is now about + 25% faster; FreeType should use less heap memory under nearly + all conditions). + + - The anti-aliased rasterizer has been optimized and is now 15% to + 25% percent faster than in previous versions, depending on + content. + + - The Type 1 loader has been improved; as an example, it now skips + top-level dictionaries properly. + + - Better support for Mac fonts on POSIX systems, plus compilation + fixes for Mac OS X on ppc64 where `ftmac.c' cannot be built. + + - Configuration without `--with-old-mac-fonts' does not include + `ftmac.c' (this was the behaviour in FreeType version 2.1.10). + + - The TrueTypeGX validator (gxvalid) checks the order of glyph IDs + in the kern table. + + +====================================================================== + +CHANGES BETWEEN 2.2.1 and 2.2 + + I. IMPORTANT BUG FIXES + + - Various integer overflows have been fixed. + + - PFB fonts with MacOS resource fork weren't handled correctly on + non-MacOS platforms. + + +====================================================================== + +CHANGES BETWEEN 2.2 and 2.1.10 + +(not released officially) + + I. IMPORTANT BUG FIXES + + - Vertical metrics for SFNT fonts were incorrect sometimes. + + - The FT_HAS_KERNING macro always returned 0. + + - CFF OpenType fonts didn't return correct vertical metrics for + glyphs with outlines. + + - If FreeType was compiled without hinters, all font formats based + on PS outlines weren't scaled correctly. + + + II. IMPORTANT CHANGES + + - Version 2.2 no longer exposes its internals, this is, the header + files located in the `include/freetype/internal' directory of + the source package are not copied anymore by the `make install' + command. Consequently, a number of rogue clients which directly + access FreeType's internal functions and structures won't + compile without modification. + + We provide patches for most of those rogue clients. See the + following page for more information: + + http://www.freetype.org/freetype2/patches/rogue-patches.html + + Note that, as a convenience to our Unix desktop users, version + 2.2 is *binary* compatible with FreeType 2.1.7, which means that + installing this release on an existing distribution shall not + break any working desktop. + + - FreeType's build mechanism has been redesigned. With GNU make + it is now sufficient in most cases to edit two files: + `modules.cfg', to select the library components, and the + configuration file `include/freetype/config/ftoption.h' (which + can be copied to the objects directory). Removing unused module + directories to prevent its compilation and editing + `include/freetype/config/ftmodule.h' is no longer necessary. + + - The LIGHT hinting algorithm produces more pleasant results. + Also, using the FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph + always forces auto-hinting, as a special exception. This allows + you to experiment with it even if you have enabled the TrueType + bytecode interpreter in your build. + + - The auto hinter now employs a new algorithm for CJK fonts, based + on Akito Hirai's patch. Note that this only works for fonts + with a Unicode charmap at the moment. + + - The following callback function types have changed slightly (by + adding the `const' keyword where appropriate): + + FT_Outline_MoveToFunc + FT_Outline_LineToFunc + FT_Outline_ConicToFunc + FT_Outline_CubicToFunc + FT_SpanFunc + FT_Raster_RenderFunc + + FT_Glyph_TransformFunc + FT_Renderer_RenderFunc + FT_Renderer_TransformFunc + + Note that this doesn't affect binary backward compatibility. + + - On MacOS, new APIs have been added as replacements for legacy + APIs: `FT_New_Face_From_FSRef' for `FT_New_Face_From_FSSpec', + and `FT_GetFile_From_Mac_ATS_Name' for + `FT_GetFile_From_Mac_Name'. Legacy APIs are still available, if + FreeType is built without disabling them. + + - A new API `FT_Select_Size' has been added to select a bitmap + strike by its index. Code using other functions to select + bitmap strikes should be updated to use this function. + + - A new API `FT_Get_SubGlyph_Info' has been added to retrieve + subglyph data. This can be used by rogue clients which used to + access the internal headers to get the corresponding data. + + - In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for + BDF/PCF fonts, and only for them. This causes inconsistency. + In this release, we undo the change. The intent of the change + in 2.1.10 is to allow size selection through real dimensions, + which can now be done through `FT_Request_Size'. + + - Some security issues were discovered and fixed in the CFF and + Type 1 loader, causing crashes of FreeType by malformed font + files. + + + III. MISCELLANEOUS + + - The documentation for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX + values now better reflects its usage and differences: One set is + used to specify the hinting algorithm, the other to specify the + pixel rendering mode. + + - `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been + changed to count supported scalable faces (sfnt, LWFN) only, and + to return the number of available faces via face->num_faces. + Unsupported bitmap faces (fbit, NFNT) are ignored. + + - builds/unix/configure has been improved for MacOS X. It now + automatically checks available functions in Carbon library, and + prepare to use newest functions by default. Options to specify + the dependencies of each Carbon APIs (FSSpec, FSRef, old/new + QuickDraw, ATS) are available too. By manual disabling of all + QuickDraw functionality, FreeType can be built without + `deprecated function' warnings on MacOS 10.4.x, but + FT_GetFile_Mac_Name in ftmac.c then is changed to a dummy + function, and returns an `unimplemented' error. For details see + builds/mac/README. + + - SFNT cmap handling has been improved, mainly to run much faster + with CJK fonts. + + - A new function `FT_Get_TrueType_Engine_Type (declared in + `FT_MODULE_H') is provided to determine the status of the + TrueType bytecode interpreter compiled into the library + (patented, unpatented, unimplemented). + + - Vertical metrics of glyphs are synthesized if the font does not + provide such information. You can tell whether the metrics are + synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of + the face. + + - The demo programs `ftview' and `ftstring' have been rewritten + for better readability. `ftview' has a new switch `-p' to test + FT_New_Memory_Face (instead of FT_New_Face). + + - FreeType now honours bit 1 in the `head' table of TrueType fonts + (meaning `left sidebearing point at x=0'). This helps with some + buggy fonts. + + - Rudimentary support for Adobe's new `SING Glyphlet' format. See + + http://www.adobe.com/products/indesign/sing_gaiji.html + + for more information. + + - The `ftdump' program from the `ft2demos' bundle now shows some + information about charmaps. It also supports a new switch `-v' + to increase verbosity. + + - Better AFM support. This includes track kerning support. + + +====================================================================== + +CHANGES BETWEEN 2.1.10 and 2.1.9 + + I. IMPORTANT BUG FIXES + + - The size comparison for BDF and PCF files could fail sometimes. + + - Some CFF files were still not loaded correctly. Patch from + Derek Noonburg. + + - The stroker still had some serious bugs. + + - Boris Letocha fixed a bug in the TrueType interpreter: The + NPUSHW instruction wasn't skipped correctly in IF clauses. Some + fonts like `Helvetica 75 Bold' failed. + + - Another serious bug in handling TrueType hints caused many + distortions. It has been introduced in version 2.1.8, and it is + highly recommended to upgrade. + + - FreeType didn't properly parse empty Type 1 glyphs. + + - An unbound dynamic buffer growth was fixed in the PFR loader. + + - Several bugs have been fixed in the cache sub-system. + + - FreeType behaved incorrectly when resizing two distinct but very + close character pixel sizes through `FT_Set_Char_Size' (Savannah + bug #12263). + + - The auto-hinter didn't work properly for fonts without a Unicode + charmap -- it even refused to load the glyphs. + + + II. IMPORTANT CHANGES + + - Many fixes have been applied to drastically reduce the amount of + heap memory used by FreeType, especially when using + memory-mapped font files (which is the default on Unix systems + which support them). + + - The auto-hinter has been replaced with a new module, called the + `auto-fitter'. It consumes less memory than its predecessor, + and it is prepared to support non-latin scripts better in next + releases. + + - George Williams contributed code to read kerning data from PFM + files. + + - FreeType now uses the TT_NAME_ID_PREFERRED_FAMILY and + TT_NAME_ID_PREFERRED_SUBFAMILY strings (if available) for + setting family and style in SFNT fonts (patch from Kornfeld + Eliyahu Peter). + + - A new API `FT_Sfnt_Table_Info' (in FT_TRUETYPE_TABLES_H) has + been added to retrieve name and size information of SFNT tables. + + - A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has + been added to validate OpenType tables (BASE, GDEF, GPOS, GSUB, + JSTF). After validation it is no longer necessary to check + for errors in those tables while accessing them. + + Note that this module might be moved to another library in the + future to avoid a tight dependency between FreeType and the + OpenType specification. + + - A new API in FT_BITMAP_H (`FT_Bitmap_New', `FT_Bitmap_Convert', + `FT_Bitmap_Copy', `FT_Bitmap_Embolden', `FT_Bitmap_Done') has + been added. Its use is to convert an FT_Bitmap structure in + 1bpp, 2bpp, 4bpp, or 8bpp format into another 8bpp FT_Bitmap, + probably using a different pitch, and to further manipulate it. + + - A new API `FT_Outline_Embolden' (in FT_OUTLINE_H) gives finer + control how outlines are embolded. + + - `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H) now handles bitmaps + also (code contributed by Chia I Wu). Note that this function + is still experimental and may be replaced with a better API. + + - The method how BDF and PCF bitmap fonts are accessed has been + refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size + were synonyms in FreeType's BDF and PCF interface. This has + changed now. FT_Set_Pixel_Sizes should be used to select the + actual font dimensions (the `strike', which is the sum of the + `FONT_ASCENT' and `FONT_DESCENT' properties), while + FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE' + property). In both functions, the width parameter is ignored. + + + III. MISCELLANEOUS + + - The BDF driver no longer converts all returned bitmaps with a + depth of 2bpp or 4bpp to a depth of 8bpp. The documentation has + not mentioned this explicitly, but implementors might have + relied on this after looking into the source files. + + - A new option `--ftversion' has been added to freetype-config to + return the FreeType version. + + - The memory debugger has been updated to dump allocation + statistics on all allocation sources in the library. This is + useful to spot greedy allocations when loading and processing + fonts. + + - We removed a huge array of constant pointers to constant strings + in the `psnames' module. The problem was that compilations in + PIC mode (i.e., when generating a Unix shared object/dll) put + the array into the non-shared writable section of the library + since absolute pointers are not relocatable by nature. + + This reduces the memory consumption by approximately 16KByte per + process linked to FreeType. We now also store the array in a + compressed form (as a trie) which saves about 20KByte of code as + well. + + - Kirill Smelkov provided patches to make src/raster/ftraster.c + compile stand-alone again. + + +====================================================================== + +CHANGES BETWEEN 2.1.9 and 2.1.8 + + I. IMPORTANT BUG FIXES + + - The function `FT_Get_CharMap_Index' was only declared, without + any real code. For consistency, it has been renamed to + `FT_Get_Charmap_Index'. (This function is needed to implement + cmap caches.) + + - `FT_Outline_Get_BBox' sometimes returned incorrect values for + conic outlines (e.g., for TrueType fonts). + + - Handling of `bhed' table has been fixed. + + - The TrueType driver with enabled byte code interpreter sometimes + returned artifacts due to incorrect rounding. This bug has been + introduced after version 2.1.4. + + - The BDF driver dropped the last glyph in the font. + + - The BDF driver now uses the DEFAULT_CHAR property (if available) + to select a glyph shape for the undefined glyph. + + - The stroker failed for closed outlines and single points. + + + II. IMPORTANT CHANGES + + - George Williams contributed code to handle Apple's font + distortion technology found in GX fonts (`avar', `cvar', `fvar', + and `gvar' tables; the Multiple Masters API has been slightly + extended to cope with the new functionality). + + - The `FT_GlyphSlotRec' structure has been extended: The elements + `lsb_delta' and `rsb_delta' give the difference between hinted + and unhinted left and right side bearings if autohinting is + active. Using those values can improve the inter-letter spacing + considerably. See the documentation of `FT_GlyphSlotRec' and + the `ftstring' demo program how to use it. + + - Loading TrueType and Type 1 fonts has been made much faster. + + - The stroker is no longer experimental (but the cache subsystem + still is). + + + III. MISCELLANEOUS + + - A new documentation file `formats.txt' describes various font + formats supported (and not supported) by FreeType. + + +====================================================================== + +CHANGES BETWEEN 2.1.8 and 2.1.7 + + I. IMPORTANT BUG FIXES + + - The native TrueType hinter contained some bugs which prevented + some fonts to be rendered correctly, most notably Legendum.otf. + + - The PostScript hinter now produces improved results. + + - The linear advance width and height values were incorrectly + rounded, making them virtually unusable if not loaded with + FT_LOAD_LINEAR_DESIGN. + + - Indexing CID-keyed CFF fonts is now working: The glyph index is + correctly treated as a CID, similar to FreeType's CID driver + module. Note that CID CMap support is still missing. + + - The FT_FACE_FLAGS_GLYPH_NAMES flag is now set correctly for all + font formats. + + - Some subsetted Type 1 fonts weren't parsed correctly. This bug + has been introduced in 2.1.7. In summary, the Type 1 parser has + become more robust. + + - Non-decimal numbers weren't parsed correctly in PS fonts. + + - The WinFNT driver now correctly reports FT_ENCODING_NONE for all + but one encoding. Use the new FT_WinFNT_ID_XXX values together + with `FT_Get_WinFNT_Header' to get the WinFNT charset ID. + + - The descender metrics (face->size->metrics.descender) for WinFNT + bitmap fonts had the wrong sign. + + - The (emulated) `seac' support for CFF fonts was broken. + + - The `flex' operator didn't work for CFF fonts. + + - PS glyphs which use the `hintmask' operator haven't been + rendered correctly in some cases. + + - Metrics for BDF and PCF bitmap font formats have been fixed. + + - Autohinting is now disabled for glyphs which are vertically + distorted or mirrored (using a transformation matrix). This + fixes a bug which produced zero-height glyphs. + + - The `freetype-config' script now handles --prefix and + --exec-prefix correctly; it also returns the proper --rpath (or + -R) value if FreeType has been built as a shared library. + + + II. IMPORTANT CHANGES + + - Both PCF and BDF drivers now handle the SETWIDTH_NAME and + ADD_STYLE_NAME properties. Values are appended to + face->style_name; example: `Bold SemiCondensed'. + + - The PCF driver now handles bitmap fonts compressed with the LZW + algorithm (extension .pcf.Z, compressed with `compress'). + + - A new API function `FT_Get_CMap_Language_ID' (declared in + `tttables.h') is available to get the language ID of a + TrueType/SFNT cmap. + + - The hexadecimal format of data after the `StartData' command in + CID-keyed Type 1 fonts is now supported. While this can't occur + in file-based fonts, it can happen in document-embedded + resources of PostScript documents. + + - Embedded bitmaps in SFNT-based CFF fonts are now supported. + + - A simple API is now available to control FreeType's tracing + mechanism if compiled with FT_DEBUG_LEVEL_TRACE. See the file + `ftdebug.h' for more details. + + - YAMATO Masatake contributed improved handling of MacOS resource + forks on non-MacOS platforms (for example, Linux can mount MacOS + file systems). + + - Support for MacOS has been improved; there is now a new function + `FT_New_Face_From_FSSpec' similar to `FT_New_Face' except that + it accepts an FSSpec instead of a path. + + - The cache sub-system has been rewritten. + + - There is now support for deinstallation of faces. + + - A new API function `FTC_Manager_RemoveFaceID' has been added + to delete all `idle' nodes that correspond to a given + FTC_FaceID. All `locked' nodes (i.e., those with a reference + count > 0), will be modified to prevent them from appearing in + further lookups (they will be cleaned normally when their + reference count reaches 0). + + - There is now support for point scaling (i.e., providing + character sizes in points + dpis, instead of pixels). + + - Three abstract cache classes are now available: + + FTC_GCache: Used to store one glyph item per cache node, + with the ability to group common attributes into + `families'. This replaces the old + FTC_GlyphCache class. + + FTC_ICache: Used to store one FT_Glyph per cache node. This + extends FTC_GCache. Family definition, family + comparison, and glyph loading are however left + to sub-classes. + + FTC_SCache: Used to store up to 16 small bitmaps per cache + node. This extends FTC_GCache. Family + definition, family comparison and glyph loading + are however left to sub-classes. + + - The file `src/cache/ftcbasic.c' implements: + + FTC_ImageCache: Extends FTC_ICache; implements family + definitions and glyph loading similar to the + old API. + + FTC_SBitCache: Extends FTC_SCache, implements family + definitions and glyph loading similar to the + old API + + Client applications should be able to extend FTC_GCache, + FTC_ICache, or FTC_SCache much more easily (i.e., less code to + write, and less callbacks). For example, one could envision + caches that are capable of storing transformed (obliqued), + stroked, emboldened, or colored glyph images. Use + `ftcbasic.c' as an example. + + - All public APIs are now in `include/freetype/ftcache.h', (to + be accessed as `FT_CACHE_H'). The contents of + `include/freetype/cache/' is only needed by applications that + wish to implement their own caches. + + - There were some major performance improvements through the use + of various programming tricks. Cache hits are up to 70% + faster than in the old code. + + - The FTC_CMapCache has been simplified. Charmaps can only be + accessed by index right now. There is also a new API named + `FT_Charmap_GetIndex' for this purpose. + + - The demo programs have been updated to the new code. The + previous versions will not work with the current one. + + - Using an invalid face index in FT_Open_Face and friends now + causes an error even if the font contains a single face only. + + + III. MISCELLANEOUS + + - Wolfgang Domröse contributed support files for building FreeType + on the Atari using the PureC compiler. Note that the Atari is a + 16bit platform. + + - Vitaliy Pasternak contributed project files for VS.NET 2003. + + +====================================================================== + +CHANGES BETWEEN 2.1.7 and 2.1.6 + + I. IMPORTANT BUG FIXES + + - Updated to newest libtool version, fixing build problems on + various platforms. + + - On Unix platforms, `make install' didn't copy the correct + `ftconfig.h' file. + + Note that version 2.1.7 contains the same library C source code as + version 2.1.6. + + +====================================================================== + +CHANGES BETWEEN 2.1.6 and 2.1.5 + + I. IMPORTANT BUG FIXES + + - The PFR font driver didn't load kerning tables correctly, and + the functions in FT_PFR_H didn't work at all. + + - Type 1 font files in binary format (PFB) with an end-of-file + indicator weren't accepted by the FreeType engine. + + - Fonts which contain /PaintType and /StrokeWidth no longer cause + a segfault. This bug has been introduced in version 2.1.5. + + - Fonts loaded with FT_LOAD_RENDER no longer cause strange + results. This bug has been introduced in version 2.1.5. + + - Some Windows (bitmap) FNT/FON files couldn't be handled + correctly. + + + II. IMPORTANT CHANGES + + - The internal module API has been heavily changed in favor of + massive simplifications within the font engine. This also means + that authors of third-party modules must adapt their code to the + new scheme. + + NOTE: THE NEW SCHEME IS NOT COMPLETED YET. PLEASE WAIT UNTIL A + FINAL ANNOUNCEMENT! + + - The PostScript parser has been enhanced to handle comments and + strings correctly. Additionally, more syntax forms are + recognized. + + - Added the optional unpatented hinting system for TrueType. It + allows typefaces which need hinting to produce correct glyph + forms (e.g., Chinese typefaces from Dynalab) to work acceptably + without infringing Apple patents. This system is compiled only + if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in + ftoption.h (activated by default). + + + III. MISCELLANEOUS + + - There is now a guard in the public header files to protect + against inclusion of freetype.h from FreeType 1. + + - Direct inclusion of freetype.h and other public header files no + longer works. You have to use the documented scheme + + #include <ft2build.h> + #include FT_FREETYPE_H + + to load freetype.h with a symbolic name. This protects against + renaming of public header files (which shouldn't happen but + actually has, avoiding two public header files with the same + name). + + +====================================================================== + +CHANGES BETWEEN 2.1.5 and 2.1.4 + + I. IMPORTANT BUG FIXES + + - Parsing the /CIDFontName field now removes the leading slash to + be in sync with other font drivers. + + - gzip support was buggy. Some fonts could not be read. + + - Fonts which have nested subglyphs more than one level deep no + longer cause a segfault. + + - Creation of synthetic cmaps for fonts in CFF format was broken + partially. + + - Numeric font dictionary entries for synthetic fonts are no + longer overwritten. + + - The font matrix wasn't applied to the advance width for Type1, + CID, and CFF fonts. This caused problems when loading certain + synthetic Type 1 fonts like `Helvetica Narrow'. + + - The test for the charset registry in BDF and PCF fonts is now + case-insensitive. + + - FT_Vector_Rotate sometimes returned strange values due to + rounding errors. + + - The PCF driver now returns the correct number of glyphs + (including an artificial `notdef' glyph at index 0). + + - FreeType now supports buggy CMaps which are contained in many + CJK fonts from Dynalab. + + - Opening an invalid font on a Mac caused a segfault due to + double-freeing memory. + + - BDF fonts with more than 32768 glyphs weren't supported + properly. + + + II. IMPORTANT CHANGES + + - Accessing bitmap font formats has been synchronized. To do that + the FT_Bitmap_Size structure has been extended to contain new + fields `size', `x_ppem', and `y_ppem'. + + - The FNT driver now returns multiple faces, not multiple strikes. + + - The `psnames' module has been updated to the Adobe Glyph List + version 2.0. + + - The `psnames' module now understands `uXXXX[X[X]]' glyph names. + + - The algorithm for guessing the font style has been improved. + + - For fonts in SFNT format, root->height is no longer increased if + the line gap is zero. There exist fonts (containing e.g. form + drawing characters) which intentionally have a zero line gap + value. + + - ft_glyph_bbox_xxx flags are now deprecated in favour of + FT_GLYPH_BBOX_XXX. + + - ft_module_xxx flags are now deprecated in favour of + FT_MODULE_XXX. + + - FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} are now + deprecated in favour of + FT_ENCODING_{SJIS,GB2312,GIB5,WANSONG,JOHAB} -- those encodings + are not specific to Microsoft. + + + III. MISCELLANEOUS + + - The autohinter has been further improved; for example, `m' + glyphs now retain its vertical symmetry. + + - Partial support of Mac fonts on non-Mac platforms. + + - `make refdoc' (after first `make') builds the HTML + documentation. You need Python for this. + + - The make build system should now work more reliably on DOS-like + platforms. + + - Support for EMX gcc and Watson C/C++ compilers on MS-DOS has + been added. + + - Better VMS build support. + + - Support for the pkg-config package by providing a `freetype.pc' + file. + + - New configure option --with-old-mac-fonts for Darwin. + + - Some source files have been renamed (mainly to fit into the 8.3 + naming scheme). + + +====================================================================== + +CHANGES BETWEEN 2.1.4 and 2.1.3 + + I. IMPORTANT BUG FIXES + + - Updated to newest libtool version, fixing build problems on + various platforms. + + - A fix in the Gzip stream reader: It couldn't read certain .gz + files properly due to a small typo. In certain cases, FreeType + could also loop endlessly when trying to load tiny gzipped + files. + + - The configure script now tries to use the system-wide zlib when + it finds one (instead of the copy found in src/gzip). And + `freetype-config' has been updated to return relevant flags in + this case when invoked with `--libs' (e.g. `-lzlib'). + + - Certain fonts couldn't be loaded by 2.1.3 because they lacked a + Unicode charmap (e.g. SYMBOL.TTF). FreeType erroneously + rejected them. + + - The CFF loader was modified to accept fonts which only contain a + subset of their reference charset. This prevented the correct + use of PDF-embedded fonts. + + - The logic to detect Unicode charmaps has been modified. This is + required to support fonts which include both 16-bit and 32-bit + charmaps (like very recent asian ones) using the new 10 and 12 + SFNT formats. + + - The TrueType loader now limits the depth of composite glyphs. + This is necessary to prevent broken fonts to break the engine by + blowing the stack with recursive glyph definitions. + + - The CMap cache is now capable of managing UCS-4 character codes + that are mapped through extended charmaps in recent + TrueType/OpenType fonts. + + - The cache sub-system now properly manages out-of-memory + conditions instead of blindly reporting them to the caller. + This means that it will try to empty the cache before restarting + its allocations to see if that can help. + + - The PFR driver didn't return the list of available embedded + bitmaps properly. + + - There was a nasty memory leak when using embedded bitmaps in + certain font formats. + + + II. IMPORTANT CHANGES + + - David Chester contributed some enhancements to the auto-hinter + that significantly increase the quality of its output. The + Postscript hinter was also improved in several ways. + + - The FT_RENDER_MODE_LIGHT render mode was implemented. + + - A new API function called `FT_Get_BDF_Property' has been added + to FT_BDF_H to retrieve BDF properties from BDF _and_ PCF font + files. THIS IS STILL EXPERIMENTAL, since it hasn't been + properly tested yet. + + - A Windows FNT specific API has been added, mostly to access font + headers. This is used by Wine. + + - TrueType tables without an `hmtx' table are now tolerated when + an incremental interface is used. This happens for certain + Type42 fonts passed from Ghostscript to FreeType. + + - The PFR font driver is now capable of returning the font family + and style names when they are available (instead of the sole + `FontID'). This is performed by parsing an *undocumented* + portion of the font file! + + + III. MISCELLANEOUS + + - The path stroker in FT_STROKER_H has entered beta stage. It now + works very well, but its interface might change a bit in the + future. More on this in later releases. + + - The documentation for FT_Size_Metrics didn't appear properly in + the API reference. + + - The file docs/VERSION.DLL has been updated to explain versioning + with FreeType (i.e., comparing release/libtool/so numbers, and + how to use them in autoconf scripts). + + - The installation documentation has been seriously revamped. + Everything is now in the `docs' directory. + + +====================================================================== + +CHANGES BETWEEN 2.1.3 and 2.1.2 + + I. IMPORTANT BUG FIXES + + - FT_Vector_Transform had been incorrectly modified in 2.1.2, + resulting in incorrect transformations being applied (for + example, rotations were processed in opposite angles). + + - The format 8 and 12 TrueType charmap enumeration routines have + been fixed (FT_Get_Next_Char returned invalid values). + + - The PFR font driver returned incorrect advance widths if the + outline and metrics resolution defined in the font file were + different. + + - FT_Glyph_To_Bitmap now returns successfully when called with an + FT_BitmapGlyph argument (it previously returned an error). + + - A bug in the Type 1 loader that prevented valid font bounding + boxes to be loaded from multiple master fonts. + + - The SFNT validation code has been rewritten. FreeType can now + load `broken' fonts that were usable on Windows, but not with + previous versions of the library. + + - The computation of bearings in the BDF driver has been fixed. + + - The Postscript hinter crashed when trying to hint certain glyphs + (more precisely, when trying to apply hints to an empty glyph + outline). + + - The TrueType glyph loader now supports composites in `Apple + format' (they differ slightly from Microsoft/OpenType ones in + the way transformation offsets are computed). + + - FreeType was very slow at opening certain asian CID/CFF fonts, + due to fixed increment in dynamic array re-allocations. This + has been changed to exponential behaviour to get acceptable + performance. + + + + II. IMPORTANT CHANGES + + - The PCF driver now supports gzip-compressed font files natively. + This means that you will be able to use all these bitmap fonts + that come with XFree86 with FreeType (and libXft/libXft2, by + extension). + + - The automatic and postscript hinters have both been updated. + This results in a relatively important increase of rendering + quality since many nasty defaults have been suppressed. Please + visit the web page: + + http://www.freetype.org/hinting/smooth-hinting.html + + for additional details on this topic. + + - The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32 + (instead of just being an FT_Int). This breaks source and + binary compatibility for 16bit systems only, while retaining + both of them for 32 and 64 bit ones. + + Some new flags have been added consequently: + + FT_LOAD_NO_AUTOHINT :: Disable the use of the auto-hinter + (but not native format hinters). + + FT_LOAD_TARGET_NORMAL :: Hint and render for normal + anti-aliased displays. + + FT_LOAD_TARGET_MONO :: Hint and render for 1-bit displays. + + FT_LOAD_TARGET_LCD :: Hint and render for horizontal RGB or + BGR sub-pixel displays (like LCD + screens). THIS IS STILL + EXPERIMENTAL! + + FT_LOAD_TARGET_LCD_V :: Same as FT_LOAD_TARGET_LCD, for + vertical sub-pixel displays (like + rotated LCD screens). THIS IS STILL + EXPERIMENTAL! + + FT_LOAD_MONOCHROME is still supported, but only affects + rendering, not the hinting. + + Note that the `ftview' demo program available in the `ft2demos' + package has been updated to support LCD-optimized display on + non-paletted displays (under Win32 and X11). + + - The PFR driver now supports embedded bitmaps (all formats + supported), and returns correct kerning metrics for all glyphs. + + - The TrueType charmap loader now supports certain `broken' fonts + that load under Windows without problems. + + - The cache API has been slightly modified (it's still a beta!): + + - The type FTC_ImageDesc has been removed; it is now replaced + by FTC_ImageTypeRec. Note that one of its fields is a + `load_flag' parameter for FT_Load_Glyph. + + - The field `num_grays' of FT_SBitRec has been changed to + `max_grays' in order to fit within a single byte. Its + maximum value is thus 255 (instead of 256 as previously). + + + III. MISCELLANEOUS + + - Added support for the DESTDIR variable during `make install'. + This simplifies packaging of FreeType. + + - Included modified copies of the ZLib sources in `src/gzip' in + order to support gzip-compressed PCF fonts. We do not use the + system-provided zlib for now, though this is a probable + enhancement for future releases. + + - The DocMaker tool used to generate the on-line API reference has + been completely rewritten. It is now located in + `src/tools/docmaker/docmaker.py'. Features: + + - better cross-referenced output + - more polished output + - uses Python regular expressions (though it didn't speed the + program) + - much more modular structure, which allows for different + `backends' in order to generate HTML, XML, or whatever + format. + + One can regenerate the API reference by calling: + + python src/tools/docmaker/docmaker.py \ + --prefix=ft2 \ + --title=FreeType-2.1.3 \ + --output=<outputdirectory> + include/freetype/*.h \ + include/freetype/config/*.h \ + include/freetype/cache/*.h + + - A new, experimental, support for incremental font loading (i.e., + loading of fonts where the glyphs are not in the font file + itself, but provided by an external component, like a Postscript + interpreter) has been added by Graham Asher. This is still work + in progress, however. + + - A new, EXPERIMENTAL, path stroker has been added. It doesn't + suffer from severe rounding errors and treat bezier arcs + directly. Still work in progress (i.e. not part of the official + API). See the file <freetype/ftstroker.h> for some of the + details. + + - The massive re-formatting of sources and internal re-design is + still under-way. Many internal functions, constants, and types + have been renamed. + + +====================================================================== + +CHANGES BETWEEN 2.1.2 and 2.1.1 + + I. IMPORTANT BUG FIXES + + - Many font drivers didn't select a Unicode charmap by default + when a new face was opened (with the FT_CONFIG_OPTION_USE_CMAPS + options enabled), causing many applications to not be able to + display text correctly with the 2.1.x releases. + + - The PFR driver had a bug in its composite loading code that + produces incorrectly placed accents with many fonts. + + - The Type42 driver crashed sometimes due to a nasty bug. + + - The Type 1 custom encoding charmap didn't handle the case where + the first glyph index wasn't 0. + + - A serious typo in the TrueType composite loader produced + incorrectly placed glyphs in fonts like `Wingdings' and a few + others. + + + II. MISCELLANEOUS + + - The Win32 Visual C++ project file has been updated to include + the PFR driver as well. + + - `freetype.m4' is now installed by default by `make install' on + Unix systems. + + - The function FT_Get_PS_Font_Info now works with CID and Type42 + fonts as well. + + +====================================================================== + +CHANGES BETWEEN 2.1.1 and 2.1.0 + + I. IMPORTANT BUG FIXES + + - The `version_info' returned by `freetype-config' in 2.1.0 + returned an invalid value. It now returns 9:1:3 (2.0.9 returned + 9:0:3). + + - Version 2.1.0 couldn't be linked against applications on Win32 + and Amiga systems due to a new debug function that wasn't + properly propagated to the system-specific directory in + `builds'. + + - Various MacOS and Mac OS X specific fixes. + + - Fixed a bug in the TrueType charmap validation routines that + made version 2.1.0 too restrictive -- many popular fonts have + been rejected. + + - There was still a very small difference between the monochrome + glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the + bytecode interpreter enabled. This was caused by an invalid + flag setting in the TrueType glyph loader, making the rasterizer + change its drop-out control mode. Now the results should + _really_ be completely identical. + + - The TrueType name table loader has been improved to support many + popular though buggy Asian fonts. It now ignores empty name + entries, invalid pointer offsets and a few other incorrect + subtleties. Moreover, name strings are now loaded on demand, + which reduces the memory load of many faces (e.g. the ARIAL.TTF + font file contains a 10kByte name table with 70 names). + + - Fixed a bug in the Postscript hinter that prevented family blues + substitution to happen correctly. + + + II. NEW FEATURES + + - Three new font drivers in this release: + + * A BDF font driver, contributed by Franco Zappa Nardelli, + heavily modified by Werner Lemberg. It also supports + anti-aliased bitmaps (using a slightly extended BDF format). + + * A Type42 font driver, contributed by Roberto Alameda. It is + still experimental but seems to work relatively well. + + * A PFR font driver, contributed by David Turner himself. It + doesn't support PFR hinting -- note that BitStream has at + least two patents on this format! + + + III. MISCELLANEOUS + + - The cache sub-system has been optimized in important ways. + Cache hits are now significantly faster. For example, using the + CMap cache is about twice faster than calling FT_Get_Char_Index + on most platforms. Similarly, using an SBit cache is about five + times faster than loading the bitmaps from a bitmap file, and + 300 to 500 times faster than generating them from a scalable + format. + + Note that you should recompile your sources if you designed a + custom cache class for the FT2 Cache subsystem, since the + changes performed are source, but not binary, compatible. + + +====================================================================== + +CHANGES BETWEEN 2.1.0 and 2.0.9 + + I. IMPORTANT BUG FIXES + + - The TrueType bytecode interpreter has been fixed to produce + _exactly_ the same output as FreeType 1.x. Previous differences + were due to slightly distinct fixed-point computation routines + used to perform dot products and vector length measurements. + + It seems that native TrueType hinting is _extremely_ sensitive + to rounding errors. The required vector computation routines + have been optimized and placed within the `ttinterp.c' file. + + - Fixed the parsing of accelerator tables in the PCF font driver. + + - Fixed the Type1 glyph loader routine used to compute the font's + maximum advance width. + + + II. NEW FEATURES + + - The `configure' script used on Unix systems has been modified to + check that GNU Make is being used to build the library. + Otherwise, it will display a message proposing to use the + GNUMAKE environment variable to name it. + + The Unix-specific file README.UNX has been modified accordingly. + + + III. MISCELLANEOUS + + - The FreeType License in `docs/FTL.TXT' has been updated to + include a proposed preferred disclaimer. If you are using + FreeType in your products, you are encouraged (but not mandated) + to use the following text in your documentation: + + """ + Portions of this software are copyright © 1996-2002 The + FreeType Project (www.freetype.org). All rights reserved. + """ + + - The default size of the render pool has been reduced to 16kByte. + This shouldn't result in any noticeable performance penalty, + unless you are using the engine as-is to render very large and + complex glyphs. + + - The FreeType 2 redesign has begun. More information can be + found at this URL: + + http://www.freetype.org/freetype2/redesign.html + + The following internal changes have been performed within the + sources of this release: + + - Many internal types have been renamed to increase + consistency. The following should be true, except for + public types: + + * All structure types have a name ending in `Rec' (short + for `record'). + + * A pointer-to-structure type has the same name as the + structure, _without_ the `Rec' suffix. + + Example: + + typedef struct FooRec_ + { + ... + + } FooRec, *Foo; + + - Many internal macros have been renamed to increase + consistency. The following should be true: + + * All macros have a name beginning with `FT_'. This + required a few changes like + + ALLOC => FT_ALLOC + FREE => FT_FREE + REALLOC => FT_REALLOC + + * All macros are completely UPPERCASE. This required a + few changes like: + + READ_Short => FT_READ_SHORT + NEXT_Short => FT_NEXT_SHORT + GET_ULongLE => FT_GET_ULONG_LE + MEM_Set => FT_MEM_SET + MEM_Copy => FT_MEM_COPY + etc. + + * Whenever possible, all macro names follow the + FT_<OBJECT>_<METHOD> pattern. For example + + ACCESS_Frame => FT_FRAME_ENTER + FORGET_Frame => FT_FRAME_EXIT + EXTRACT_Frame => FT_FRAME_EXTRACT + RELEASE_Frame => FT_FRAME_RELEASE + + FILE_Pos => FT_STREAM_POS + FILE_Seek => FT_STREAM_SEEK + FILE_Read => FT_STREAM_READ + FILE_ReadAt => FT_STREAM_READ_AT + READ_Fields => FT_STREAM_READ_FIELDS + + - Many internal functions have been renamed to follow the + FT_<Object>_<Method> pattern. For example: + + FT_Seek_Stream => FT_Stream_Seek + FT_Read_Stream_At => FT_Stream_ReadAt + FT_Done_Stream => FT_Stream_Close + FT_New_Stream => FT_Stream_Open + FT_New_Memory_Stream => FT_Stream_OpenMemory + FT_Extract_Frame => FT_Stream_ExtractFrame + + Note that method names do not contain `_'. + + - The FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been replaced + with FT_NEW_ARRAY and FT_RENEW_ARRAY which do not take a + type as the fourth argument. Instead, the array element + type size is computed automatically from the type of the + target pointer used. + + - A new object class, FT_CMap, has been introduced. These + internal objects are used to model character maps. This + eases the support of additional charmap types within the + engine. + + - A new configuration file named `ftstdlib.h' has been added + to `include/freetype/config'. It is used to define aliases + for _every_ routine of the ISO C library that the font + engine uses. Each aliases has a `ft_' prefix + (e.g. `ft_strlen' is an alias for `strlen'). + + This is used to ease the porting of FreeType 2 to exotic + runtime environments where the ISO C Library isn't available + (e.g. XFree86 extension modules). + + More details are available in the `ChangeLog' file. + + +====================================================================== + +CHANGES BETWEEN 2.0.9 and 2.0.8 + + I. IMPORTANT BUG FIXES + + - Certain fonts like `foxjump.ttf' contain broken name tables with + invalid entries and wild offsets. This caused FreeType to crash + when trying to load them. + + The SFNT `name' table loader has been fixed to be able to + support these strange fonts. + + Moreover, the code in charge of processing this table has been + changed to always favour Windows-formatted entries over other + ones. Hence, a font that works on Windows but not on the Mac + will load cleanly in FreeType and report accurate values for + Family & PostScript names. + + - The CID font driver has been fixed. It unfortunately returned a + Postscript Font name with a leading slash, as in + `/MunhwaGothic-Regular'. + + - FreeType 2 should now compile fine on AIX 4.3.3 as a shared + library. + + - A bug in the Postscript hinter has been found and fixed, + removing un-even stem widths at small pixel sizes (like 14-17). + + This improves the quality of a certain number of Postscript + fonts. + + + II. NEW FEATURES + + - A new function named `FT_Library_Version' has been added to + return the current library's major, minor, and patch version + numbers. This is important since the macros FREETYPE_MAJOR, + FREETYPE_MINOR, and FREETYPE_PATCH cannot be used when the + library is dynamically linked by a program. + + - Two new APIs have been added: `FT_Get_First_Char' and + `FT_Get_Next_Char'. + + Together, these can be used to iterate efficiently over the + currently selected charmap of a given face. Read the API + reference for more details. + + + III. MISCELLANEOUS + + - The FreeType sources are under heavy internal re-factoring. As + a consequence, we have created a branch named `STABLE' on the + CVS to hold all future releases/fixes in the 2.0.x family. + + The HEAD branch now contains the re-factored sources and + shouldn't be used for testing or packaging new releases. In + case you would like to access the 2.0.9 sources from our CVS + repository, use the tag `VER-2-0-9'. + + +====================================================================== + +CHANGES BETWEEN 2.0.8 and 2.0.7 + + I. IMPORTANT BUG FIXES + + - There was a small but nasty bug in `freetype-config.in' which + caused the `freetype-config' script to fail on Unix. + + This didn't prevent the installation of the library or even its + execution, but caused problems when trying to compile many Unix + packages that depend on it. + + - Some TrueType or OpenType fonts embedded in PDF documents do not + have a 'cmap', 'post' and 'name' as is required by the + specification. FreeType no longer refuses to load such fonts. + + - Various fixes to the PCF font driver. + + +====================================================================== + +CHANGES BETWEEN 2.0.7 and 2.0.6 + + I. IMPORTANT BUG FIXES + + - Fixed two bugs in the Type 1 font driver. The first one + resulted in a memory leak in subtle cases. The other one caused + FreeType to crash when trying to load `.gsf' files (Ghostscript + so-called Postscript fonts). + + (This made _many_ KDE applications crash on certain systems. + FreeType _is_ becoming a critical system component on Linux :-) + + - Fixed a memory leak in the CFF font driver. + + - Fixed a memory leak in the PCF font driver. + + - Fixed the Visual C++ project file + `builds/win32/visualc/freetype.dsp' since it didn't include the + Postscript hinter component, causing errors at build time. + + - Fixed a small rendering bug in the anti-aliased renderer that + only occurred when trying to draw thin (less than 1 pixel) + strokes. + + - Fixed `builds/unix/freetype2.a4' which is used to generate a + valid `freetype2.m4' for use with autoconf. + + - Fixed the OpenVMS Makefiles. + + + II. MISCELLANEOUS + + - Added `configure' and `install' scripts to the top-level + directory. A GNU-style installation is thus now easily possible + with + + ./configure <options> + make + make install + + +====================================================================== + +CHANGES BETWEEN 2.0.6 and 2.0.5 + + I. IMPORTANT BUG FIXES + + - It wasn't possible to load embedded bitmaps when the auto-hinter + was used. This is now fixed. + + - The TrueType font driver didn't load some composites properly + (the sub-glyphs were slightly shifted, and this was only + noticeable when using monochrome rendering). + + - Various fixes to the auto-hinter. They merely improve the + output of sans-serif fonts. Note that there are still problems + with serifed fonts and composites (accented characters). + + - All scalable font drivers erroneously returned un-fitted glyph + advances when hinting was requested. This created problems for + a number of layout applications. This is a very old bug that + got undetected mainly because most test/demo program perform + rounding explicitly or implicitly (through the cache). + + - `FT_Glyph_To_Bitmap' did erroneously modify the source glyph in + certain cases. + + - `glnames.py' still contained a bug that made FreeType return + invalid names for certain glyphs. + + - The library crashed when loading certain Type 1 fonts like + `sadn.pfb' (`Stalingrad Normal'), which appear to contain + pathetic font info dictionaries. + + - The TrueType glyph loader is now much more paranoid and checks + everything when loading a given glyph image. This was necessary + to avoid problems (crashes and/or memory overwrites) with broken + fonts that came from a really buggy automatic font converter. + + + II. IMPORTANT UPDATES AND NEW FEATURES + + - Important updates to the Mac-specific parts of the library. + + - The caching sub-system has been completely re-designed, and its + API has evolved (the old one is still supported for backward + compatibility). + + The documentation for it is not yet completed, sorry. For now, + you are encouraged to continue using the old API. However, the + ftview demo program in the ft2demos package has already been + updated to use the new caching functions. + + - A new charmap cache is provided too. See `FTC_CMapCache'. This + is useful to perform character code -> glyph index translations + quickly, without the need for an opened FT_Face. + + - A NEW POSTSCRIPT HINTER module has been added to support native + hints in the following formats: PostScript Type 1, PostScript + CID, and CFF/CEF. + + Please test! Note that the auto-hinter produces better results + for a number of badly-hinted fonts (mostly auto-generated ones) + though. + + - A memory debugger is now part of the standard FreeType sources. + To enable it, define FT_DEBUG_MEMORY in + <freetype/config/ftoption.h>, and recompile the library. + + Additionally, define the _environment_ variable FT_DEBUG_MEMORY + and run any program using FreeType. When the library is exited, + a summary of memory footprints and possible leaks will be + displayed. + + This works transparently with _any_ program that uses FreeType. + However, you will need a lot of memory to use this (allocated + blocks are never released to the heap to detect double deletes + easily). + + + III. MISCELLANEOUS + + - We are aware of subtle differences between the output of + FreeType versions 1 and 2 when it comes to monochrome + TrueType-hinted glyphs. These are most probably due to small + differences in the monochrome rasterizers and will be worked out + in an upcoming release. + + - We have decided to fork the sources in a `stable' branch, and an + `unstable' one, since FreeType is becoming a critical component + of many Unix systems. + + The next bug-fix releases of the library will be named 2.0.7, + 2.0.8, etc., while the `2.1' branch will contain a version of + the sources where we will start major reworking of the library's + internals, in order to produce FreeType 2.2.0 (or even 3.0) in a + more distant future. + + We also hope that this scheme will allow much more frequent + releases than in the past. + + +====================================================================== + +CHANGES BETWEEN 2.0.5 and 2.0.4 + + NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER. THIS MODULE + WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1) + + - Fixed a bug that made certain glyphs, like `Cacute', `cacute' and + `lslash' unavailable from Unicode charmaps of Postscript fonts. + This prevented the correct display of Polish text, for example. + + - The kerning table of Type 1 fonts was loaded by FreeType, when its + AFM file was attached to its face, but the + FT_FACE_FLAG_HAS_KERNING bit flags was not set correctly, + preventing FT_Get_Kerning to return meaningful values. + + - Improved SFNT (TrueType & OpenType) charmap support. Slightly + better performance, as well as support for the new formats defined + by the OpenType 1.3 specification (8, 10, and 12) + + - Fixed a serious typo in `src/base/ftcalc.c' which caused invalid + computations in certain rare cases, producing ugly artefacts. + + - The size of the EM square is computed with a more accurate + algorithm for Postscript fonts. The old one caused slight errors + with embedded fonts found in PDF documents. + + - Fixed a bug in the cache manager that prevented normal LRU + behaviour within the cache manager, causing unnecessary reloads + (for FT_Face and FT_Size objects only). + + - Added a new function named `FT_Get_Name_Index' to retrieve the + glyph index of a given glyph name, when found in a face. + + - Added a new function named `FT_Get_Postscript_Name' to retrieve + the `unique' Postscript font name of a given face. + + - Added a new public header size named FT_SIZES_H (or + <freetype/ftsizes.h>) providing new FT_Size-management functions: + FT_New_Size, FT_Activate_Size, FT_Done_Size. + + - Fixed a reallocation bug that generated a dangling pointer (and + possibly memory leaks) with Postscript fonts (in + src/psaux/psobjs.c). + + - Many fixes for 16-bit correctness. + + - Removed many pedantic compiler warnings from the sources. + + - Added an Amiga build directory in `builds/amiga'. + + +====================================================================== + +CHANGES BETWEEN 2.0.4 and 2.0.3 + + - Fixed a rather annoying bug that was introduced in 2.0.3. Namely, + the font transformation set through FT_Set_Transform was applied + twice to auto-hinted glyphs, resulting in incorrectly rotated text + output. + + - Fixed _many_ compiler warnings. FT2 should now compile cleanly + with Visual C++'s most pedantic warning level (/W4). It already + compiled fine with GCC and a few other compilers. + + - Fixed a bug that prevented the linear advance width of composite + TrueType glyphs to be correctly returned. + + - Fixed the Visual C++ project files located in + `builds/win32/visualc' (previous versions used older names of the + library). + + - Many 32-bit constants have an `L' appended to their value, in + order to improve the 16-bitness of the code. Someone is actually + trying to use FT2 on an Atari ST machine! + + - Updated the `builds/detect.mk' file in order to automatically + build FT2 on AIX systems. AIX uses `/usr/sbin/init' instead of + `/sbin/init' and wasn't previously detected as a Unix platform by + the FreeType build system. + + - Updated the Unix-specific portions of the build system (new + libtool version, etc.). + + - The SFNT kerning loader now ensures that the table is sorted + (since some problem fonts do not meet this requirement). + + +======================================================================= + +CHANGES BETWEEN 2.0.3 and 2.0.2 + + I. CHANGES TO THE MODULES / FONT DRIVERS + + - THE AUTO-HINTER HAS BEEN SLIGHTLY IMPROVED, in order to fix + several annoying artefacts, mainly: + + - Blue zone alignment of horizontal stems wasn't performed + correctly, resulting in artefacts like the `d' being placed + one pixel below the `b' in some fonts like Time New Roman. + + - Overshoot thresholding wasn't performed correctly, creating + unpleasant artefacts at large character pixel sizes. + + - Composite glyph loading has been simplified. This gets rid + of various artefacts where the components of a composite + glyphs were not correctly spaced. + + These are the last changes to the current auto-hinting module. + A new hinting sub-system is currently in the work in order to + support native hints in Type 1 / CFF / OpenType fonts, as well + as globally improve rendering. + + - The PCF driver has been fixed. It reported invalid glyph + dimensions for the fonts available on Solaris. + + - The Type 1, CID and CFF drivers have been modified to fix the + computation of the EM size. + + - The Type 1 driver has been fixed to avoid a dangerous bug that + crashed the library with non-conforming fonts (i.e. ones that do + not place the .notdef glyph at position 0). + + - The TrueType driver had a rather subtle bug (dangling pointer + when loading composite glyphs) that could crash the library in + rare occasions! + + + II. HIGH-LEVEL API CHANGES + + - The error code enumeration values have been changed. An error + value is decomposed in a generic error code, and a module + number. see <freetype/fterrors.h> for details. + + - A new public header file has been introduced, named + FT_TRIGONOMETRY_H (include/freetype/fttrig.h), providing + trigonometric functions to compute sines, cosines, arctangents, + etc. with 16.16 fixed precision. The implementation is based on + the CORDIC algorithm and is very fast while being sufficiently + accurate. + + + III. INTERNALS + + - Added BeOS-specific files in the old build sub-system. Note + that no changes were required to compile the library with Jam. + + - The configuration is now capable of automatically detecting + 64-bit integers on a set of predefined compilers (GCC, Visual + C++, Borland C++) and will use them by default. This provides a + small performance boost. + + - A small memory leak that happened when opening 0-sized files + (duh!) have been fixed. + + - Fixed bezier stack depth bug in the routines provided by the + FT_BBOX_H header file. Also fixed similar bugs in the + rasterizers. + + - The outline bounding box code has been rewritten to use direct + computations, instead of bezier sub-division, to compute the + exact bounding box of glyphs. This is slightly slower but more + accurate. + + - The build system has been improved and fixed, mainly to support + `make' on Windows 2000 correctly, avoid problems with `make + distclean' on non Unix systems, etc. + + - Hexadecimal constants have been suffixed with `U' to avoid + problems with certain compilers on 64-bit platforms. + + - A new directory named `src/tools' has been created. It contains + Python scripts and simple unit test programs used to develop the + library. + + - The DocMaker tool has been moved from `docs' to `src/tools' and + has been updated with the following: + + - Now accepts the `--title=XXXX' or `-t XXXX' option from the + command line to set the project's name in the generated API + reference. + + - Now accepts the `--output=DIR' or `-o DIR' option from the + command line to set the output directory for all generated + HTML files. + + - Now accepts the `--prefix=XXXX' or `-p XXX' option from the + command line to set the file prefix to use for all + generated HTML files. + + - Now generates the current time/data on each generated page + in order to distinguish between versions. + + DocMaker can be used with other projects now, not only FT2 + (e.g. MLib, FTLayout, etc.). + + +====================================================================== + +CHANGES BETWEEN 2.0.2 and 2.0.1 + + I. CHANGES TO THE MODULES / FONT DRIVERS + + - THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to + avoid legal problems with the Apple patents. It seems that we + mistakenly turned this option on in previous releases of the + build. + + Note that if you want to use the bytecode interpreter in order + to get high-quality TrueType rendering, you will need to toggle + by hand the definition of the + TT_CONFIG_OPTION_BYTECODE_INTERPRETER macro in the file + `include/freetype/config/ftoption.h'. + + - The CFF driver has been improved by Tom Kacvinsky and Sander van + der Wal: + + * Support for `seac' emulation. + * Support for `dotsection'. + * Support for retrieving glyph names through + `FT_Get_Glyph_Name'. + + The first two items are necessary to correctly a large number of + Type 1 fonts converted to the CFF formats by Adobe Acrobat. + + - The Type 1 driver was also improved by Tom & others: + + * Better EM size computation. + * Better support for synthetic (transformed) fonts. + * The Type 1 driver returns the charstrings corresponding to + each glyph in the `glyph->control_data' field after a call to + `FT_Load_Glyph' (thanks Ha Shao). + + - Various other bugfixes, including the following: + + * Fixed a nasty memory leak in the Type 1 driver. + * The autohinter and the pcf driver used static writable data + when they shouldn't. + * Many casts were added to make the code more 64-bits safe. It + also now compiles on Windows XP 64-bits without warnings. + * Some incorrect writable statics were removed in the `autohint' + and `pcf' drivers. FreeType 2 now compiles on Epoc again. + + + II. CHANGES TO THE HIGH-LEVEL API + + - The library header files inclusion scheme has been changed. The + old scheme looked like: + + #include <freetype/freetype.h> + #include <freetype/ftglyph.h> + #include <freetype/ftcache.h> + #include <freetype/cache/ftimage.h> + + Now you should use: + + #include <ft2build.h> + #include FT_FREETYPE_H + #include FT_GLYPH_H + #include FT_CACHE_H + #include FT_CACHE_IMAGE_H + + NOTE THAT THE OLD INCLUSION SCHEME WILL STILL WORK WITH THIS + RELEASE. HOWEVER, WE DO NOT GUARANTEE THAT THIS WILL STILL BE + TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1). + + The file <ft2build.h> is used to define the header filename + macros. The complete and commented list of macros is available + in the API reference under the section name `Header File Macros' + in Chapter I. + + For more information, see section I of the following document: + + http://www.freetype.org/ + freetype2/docs/tutorial/step1.html + + or + + http://freetype.sourceforge.net/ + freetype2/docs/tutorial/step1.html + + - Many, many comments have been added to the public source file in + order to automatically generate the API Reference through the + `docmaker.py' Python script. + + The latter has been updated to support the grouping of sections + in chapters and better index sort. See: + + http://www.freetype.org/freetype2/docs/reference/ft2-toc.html + + + III. CHANGES TO THE BUILD PROCESS + + - If you are not building FreeType 2 with its own build system + (but with your own Makefiles or project files), you will need to + be aware that the build process has changed a little bit. + + You don't need to put the `src' directory in the include path + when compiling any FT2 component. Instead, simply put the + component's directory in the current include path. + + So, if you were doing something like: + + cc -c -Iinclude -Isrc src/base/ftbase.c + + change the line to: + + cc -c -Iinclude -Isrc/base src/base/ftbase.c + + If you were doing something like: + + cd src/base + cc -c -I../../include -I.. ftbase.c + + change it to: + + cd src/base + cc -c -I../../include ftbase.c + + +====================================================================== + +CHANGES BETWEEN 2.0.1 and 2.0 + + 2.0.1 introduces a few changes: + + - Fixed many bugs related to the support of CFF / OpenType fonts. + These formats are now much better supported though there is + still work planned to deal with charset tables and PDF-embedded + CFF files that use the old `seac' command. + + - The library could not be compiled in debug mode with a very + small number of C compilers whose pre-processors didn't + implement the `##' directive correctly (i.e. per se the ANSI C + specification!) An elegant fix was found. + + - Added support for the free Borland command-line C++ Builder + compiler. Use `make setup bcc32'. Also fixed a few source + lines that generated new warnings with BCC32. + + - Fixed a bug in FT_Outline_Get_BBox when computing the extrema of + a conic Bezier arc. + + - Updated the INSTALL file to add IDE compilation. + + - Other minor bug fixes, from invalid Type 1 style flags to + correct support of synthetic (obliqued) fonts in the + auto-hinter, better support for embedded bitmaps in a SFNT font. + + - Fixed some problems with `freetype-config'. + + Finally, the `standard' scheme for including FreeType headers is now + gradually changing, but this will be explained in a later release + (probably 2.0.2). + + And very special thanks to Tom Kacvinsky and YAMANO-UCHI Hidetoshi + for their contributions! + + +====================================================================== + +CHANGES BETWEEN beta8 and 2.0 + + - Changed the default installation path for public headers from + `include/freetype' to `include/freetype2'. + + Also added a new `freetype-config' that is automatically generated + and installed on Unix and Cygwin systems. The script itself is + used to retrieve the current install path, C compilation flags as + well as linker flags. + + - Fixed several small bugs: + + * Incorrect max advance width for fixed-pitch Type 1 fonts. + * Incorrect glyph names for certain TrueType fonts. + * The glyph advance was not copied when FT_Glyph_To_Bitmap was + called. + * The linearHoriAdvance and linearVertAdvance fields were not + correctly returned for glyphs processed by the auto-hinter. + * `type1z' renamed back to `type1'; the old `type1' module has + been removed. + + - Revamped the build system to make it a lot more generic. This + will allow us to re-use nearly un-modified in lots of other + projects (including FreeType Layout). + + - Changed `cid' to use `psaux' too. + + - Added the cache sub-system. See <freetype/ftcache.h> as well as + the sources in `src/cache'. Note that it compiles but is still + untested for now. + + - Updated `docs/docmaker.py', a draft API reference is available at + http://www.freetype.org/ft2api.html. + + - Changed `type1' to use `psaux'. + + - Created a new module named `psaux' to hold the Type 1 & Type 2 + parsing routines. It should be used by `type1', `cid', and `cff' + in the future. + + - Fixed an important bug in `FT_Glyph_Get_CBox'. + + - Fixed some compiler warnings that happened since the TrueType + bytecode decoder was deactivated by default. + + - Fixed two memory leaks: + + * The memory manager (16 bytes) isn't released in + FT_Done_FreeType! + * Using custom input streams, the copy of the original stream was + never released. + + - Fixed the auto-hinter by performing automatic computation of the + `filling direction' of each glyph. This is done through a simple + and fast approximation, and seems to work (problems spotted by + Werner though). The Arphic fonts are a lot nicer though there are + still a lot of things to do to handle Asian fonts correctly. + + +====================================================================== + +BETA-8 (RELEASE CANDIDATE) CHANGES + + - Deactivated the TrueType bytecode interpreter by default. + + - Deactivated the `src/type1' font driver. Now `src/type1z' is used + by default. + + - Updates to the build system. We now compile the library correctly + under Unix system through `configure' which is automatically + called on the first `make' invocation. + + - Added the auto-hinting module! Fixing some bugs here and there. + + - Found some bugs in the composite loader (seac) of the Type1-based + font drivers. + + - Renamed the directory `freetype2/config' to `freetype2/builds' and + updated all relevant files. + + - Found a memory leak in the `type1' driver. + + - Incorporated Tom's patches to support flex operators correctly in + OpenType/CFF fonts. Now all I need is to support pure CFF and CEF + fonts to be done with this driver :-) + + - Added the Windows FNT/FON driver in `src/winfonts'. For now, it + always `simulates' a Unicode charmap, so it shouldn't be + considered completed right now. + + It is there to be more a proof of concept than anything else + anyway. The driver is a single C source file, that compiles to 3 + Kb of code. + + I'm still working on the PCF/BDF drivers, but I'm too lazy to + finish them now. + + - CHANGES TO THE HIGH-LEVEL API + + * FT_Get_Kerning has a new parameter that allows you to select the + coordinates of the kerning vector (font units, scaled, scaled + + grid-fitted). + * The outline functions are now in <freetype/ftoutln.h> and not + part of <freetype/freetype.h> anymore. + * <freetype/ftmodule.h> now contains declarations for + FT_New_Library, FT_Done_Library, FT_Add_Default_Modules. + * The so-called convenience functions have moved from `ftoutln.c' + to `ftglyph.c', and are thus available with this optional + component of the library. They are declared in + <freetype/ftglyph.h> now. + * Anti-aliased rendering is now the default for FT_Render_Glyph + (i.e. corresponds to render_mode == 0 == ft_render_mode_normal). + To generate a monochrome bitmap, use ft_render_mode_mono, or the + FT_LOAD_MONOCHROME flag in FT_Load_Glyph/FT_Load_Char. + FT_LOAD_ANTI_ALIAS is still defined, but values to 0. + * <freetype/freetype.h> now include <freetype/config/ftconfig.h>, + solving a few headaches :-) + * The type FT_GlyphSlotRec has now a `library' field. + + - CHANGES TO THE `ftglyph.h' API + + This API has been severely modified in order to make it simpler, + clearer, and more efficient. It certainly now looks like a real + `glyph factory' object, and allows client applications to manage + (i.e. transform, bbox and render) glyph images without ever + knowing their original format. + + - Added support for CID-keyed fonts to the CFF driver. Maybe + support for pure CFF + CEF fonts should come in? + + - Cleaned up source code in order to avoid two functions with the + same name. Also changed the names of the files in `type1z' from + `t1XXXX' to `z1XXXX' in order to avoid any conflicts. + + `make multi' now works well :-) + + Also removed the use of `cidafm' for now, even if the source files + are still there. This functionality will certainly go into a + specific module. + + - ADDED SUPPORT FOR THE AUTO-HINTER + + It works :-) I have a demo program which simply is a copy of + `ftview' that does a `FT_Add_Module(library, + &autohinter_module_class)' after library initialization, and Type + 1 & OpenType/CFF fonts are now hinted. + + CID fonts are not hinted, as they include no charmap and the + auto-hinter doesn't include `generic' global metrics computations + yet. + + Now, I need to release this thing to the FreeType 2 source. + + - CHANGES TO THE RENDERER MODULES + + The monochrome and smooth renderers are now in two distinct + directories, namely `src/raster1' and `src/smooth'. Note that the + old `src/renderer' is now gone. + + I ditched the 5-gray-levels renderers. Basically, it involved a + simple #define toggle in 'src/raster1/ftraster.c'. + + FT_Render_Glyph, FT_Outline_Render & FT_Outline_Get_Bitmap now + select the best renderer available, depending on render mode. If + the current renderer for a given glyph image format isn't capable + of supporting the render mode, another one will be found in the + library's list. This means that client applications do not need + to switch or set the renderers themselves (as in the latest + change), they'll get what they want automatically. At last. + + Changed the demo programs accordingly. + + - MAJOR INTERNAL REDESIGN: + + A lot of internal modifications have been performed lately on the + source in order to provide the following enhancements: + + * More generic module support: + + The FT_Module type is now defined to represent a handle to a + given module. The file <freetype/ftmodule.h> contains the + FT_Module_Class definition, as well as the module-loading public + API. + + The FT_Driver type is still defined, and still represents a + pointer to a font driver. Note that FT_Add_Driver is replaced + by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc. + + * Support for generic glyph image types: + + The FT_Renderer type is a pointer to a module used to perform + various operations on glyph image. + + Each renderer is capable of handling images in a single format + (e.g. ft_glyph_format_outline). Its functions are used to: + + - transform an glyph image + - render a glyph image into a bitmap + - return the control box (dimensions) of a given glyph image + + The scan converters `ftraster.c' and `ftgrays.c' have been moved + to the new directory `src/renderer', and are used to provide two + default renderer modules. + + One corresponds to the `standard' scan-converter, the other to + the `smooth' one. + + he current renderer can be set through the new function + FT_Set_Renderer. + + The old raster-related function FT_Set_Raster, FT_Get_Raster and + FT_Set_Raster_Mode have now disappeared, in favor of the new: + + FT_Get_Renderer + FT_Set_Renderer + + See the file <freetype/ftrender.h> for more details. + + These changes were necessary to properly support different + scalable formats in the future, like bi-color glyphs, etc. + + * Glyph loader object: + + A new internal object, called a 'glyph loader' has been + introduced in the base layer. It is used by all scalable format + font drivers to load glyphs and composites. + + This object has been created to reduce the code size of each + driver, as each one of them basically re-implemented its + functionality. + + See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for + more information. + + * FT_GlyphSlot has new fields: + + In order to support extended features (see below), the + FT_GlyphSlot structure has a few new fields: + + linearHoriAdvance: + + This field gives the linearly scaled (i.e. scaled but + unhinted) advance width for the glyph, expressed as a 16.16 + fixed pixel value. This is useful to perform WYSIWYG text. + + linearVertAdvance: + This field gives the linearly scaled advance height for the + glyph (relevant in vertical glyph layouts only). This is + useful to perform WYSIWYG text. + + Note that the two above field replace the removed `metrics2' + field in the glyph slot. + + advance: + This field is a vector that gives the transformed advance for + the glyph. By default, it corresponds to the advance width, + unless FT_LOAD_VERTICAL_LAYOUT was specified when calling + FT_Load_Glyph or FT_Load_Char. + + bitmap_left: + This field gives the distance in integer pixels from the + current pen position to the left-most pixel of a glyph image + IF IT IS A BITMAP. It is only valid when the `format' field + is set to `ft_glyph_format_bitmap', for example, after calling + the new function FT_Render_Glyph. + + bitmap_top: + This field gives the distance in integer pixels from the + current pen position (located on the baseline) to the top-most + pixel of the glyph image IF IT IS A BITMAP. Positive values + correspond to upwards Y. + + loader: + This is a new private field for the glyph slot. Client + applications should not touch it. + + + * Support for transforms and direct rendering in FT_Load_Glyph: + + Most of the functionality found in <freetype/ftglyph.h> has been + moved to the core library. Hence, the following: + + - A transform can be specified for a face through + FT_Set_Transform. this transform is applied by FT_Load_Glyph + to scalable glyph images (i.e. NOT TO BITMAPS) before the + function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM + was set in the load flags. + + - Once a glyph image has been loaded, it can be directly + converted to a bitmap by using the new FT_Render_Glyph + function. Note that this function takes the glyph image from + the glyph slot, and converts it to a bitmap whose properties + are returned in `face.glyph.bitmap', `face.glyph.bitmap_left' + and `face.glyph.bitmap_top'. The original native image might + be lost after the conversion. + + - When using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph + and FT_Load_Char functions will call FT_Render_Glyph + automatically when needed. + + - Reformatted all modules source code in order to get rid of the + basic data types redifinitions (i.e. `TT_Int' instead of `FT_Int', + `T1_Fixed' instead of `FT_Fixed'). Hence the format-specific + prefixes like `TT_', `T1_', `T2_' and `CID_' are only used for + relevant structures. + + +====================================================================== + +OLD CHANGES FOR BETA 7 + + - bug-fixed the OpenType/CFF parser. It now loads and displays my + two fonts nicely, but I'm pretty certain that more testing is + needed :-) + + - fixed the crummy Type 1 hinter, it now handles accented characters + correctly (well, the accent is not always well placed, but that's + another problem..) + + - added the CID-keyed Type 1 driver in `src/cid'. Works pretty well + for only 13 Kb of code ;-) Doesn't read AFM files though, nor the + really useful CMAP files.. + + - fixed two bugs in the smooth renderer (src/base/ftgrays.c). + Thanks to Boris Letocha for spotting them and providing a fix. + + - fixed potential `divide by zero' bugs in ftcalc.c. + + - added source code for the OpenType/CFF driver (still incomplete + though..) + + - modified the SFNT driver slightly to perform more robust header + checks in TT_Load_SFNT_Header. This prevents certain font files + (e.g. some Type 1 Multiple Masters) from being incorrectly + `recognized' as TrueType font files.. + + - moved a lot of stuff from the TrueType driver to the SFNT module, + this allows greater code re-use between font drivers + (e.g. TrueType, OpenType, Compact-TrueType, etc..) + + - added a tiny segment cache to the SFNT Charmap 4 decoder, in order + to minimally speed it up.. + + - added support for Multiple Master fonts in `type1z'. There is + also a new file named <freetype/ftmm.h> which defines functions to + manage them from client applications. + + The new file `src/base/ftmm.c' is also optional to the engine.. + + - various formatting changes (e.g. EXPORT_DEF -> FT_EXPORT_DEF) + + small bug fixes in FT_Load_Glyph, the `type1' driver, etc.. + + - a minor fix to the Type 1 driver to let them apply the font matrix + correctly (used for many oblique fonts..) + + - some fixes for 64-bit systems (mainly changing some FT_TRACE calls + to use %p instead of %lx). Thanks to Karl Robillard. + + - fixed some bugs in the sbit loader (src/base/sfnt/ttsbit.c) + + added a new flag, FT_LOAD_CROP_BITMAP to query that bitmaps be + cropped when loaded from a file (maybe I should move the bitmap + cropper to the base layer ??). + + - changed the default number of gray levels of the smooth renderer + to 256 (instead of the previous 128). Of course, the human eye + can't see any difference ;-) + + - removed TT_MAX_SUBGLYPHS, there is no static limit on the number + of subglyphs in a TrueType font now.. + + +====================================================================== + +OLD CHANGES 16 May 2000 + + - tagged `BETA-6' in the CVS tree. This one is a serious release + candidate even though it doesn't incorporate the auto-hinter yet.. + + - various obsolete files were removed, and copyright header updated + + - finally updated the standard raster to fix the monochrome + rendering bug + re-enable support for 5-gray levels anti-aliasing + (suck, suck..) + + - created new header files, and modified sources accordingly: + + <freetype/fttypes.h> + - simple FreeType types, without the API + <freetype/internal/ftmemory.h> + - definition of memory-management macros + + - added the `DSIG' (OpenType Digital Signature) tag to + <freetype/tttags.h> + + - light update/cleaning of the build system + changes to the sources + in order to get rid of _all_ compiler warnings with three + compilers, i.e: + + gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and + LCC + + IMPORTANT NOTE FOR WIN32-LCC USERS: + | + | It seems the C pre-processor that comes with LCC is broken, it + | doesn't recognize the ANSI standard directives # and ## + | correctly when one of the argument is a macro. Also, + | something like: + | + | #define F(x) print##x + | + | F(("hello")) + | + | will get incorrectly translated to: + | + | print "hello") + | + | by its pre-processor. For this reason, you simply cannot build + | FreeType 2 in debug mode with this compiler.. + + - yet another massive grunt work. I've changed the definition of + the EXPORT_DEF, EXPORT_FUNC, BASE_DEF & BASE_FUNC macros. These + now take an argument, which is the function's return value type. + + This is necessary to compile FreeType as a DLL on Windows and + OS/2. Depending on the compiler used, a compiler-specific keyword + like __export or __system must be placed before (VisualC++) or + after (BorlandC++) the type.. + + Of course, this needed a lot of changes throughout the source code + to make it compile again... All cleaned up now, apparently.. + + Note also that there is a new EXPORT_VAR macro defined to allow + the _declaration_ of an exportable public (constant) + variable. This is the case of the raster interfaces (see + ftraster.h and ftgrays.h), as well as each module's interface (see + sfdriver.h, psdriver.h, etc..) + + - new feature: it is now possible to pass extra parameters to font + drivers when creating a new face object. For now, + this capability is unused. It could however prove to + be useful in a near future.. + + the FT_Open_Args structure was changes, as well as the internal + driver interface (the specific `init_face' module function has + now a different signature). + + - updated the tutorial (not finished though). + + - updated the top-level BUILD document + + - fixed a potential memory leak that could occur when loading + embedded bitmaps. + + - added the declaration of FT_New_Memory_Face in + <freetype/freetype.h>, as it was missing from the public header + (the implementation was already in `ftobjs.c'). + + - the file <freetype/fterrors.h> has been seriously updated in order + to allow the automatic generation of error message tables. See + the comments within it for more information. + + - major directory hierarchy re-organisation. This was done for two + things: + + * first, to ease the `manual' compilation of the library by + requiring at lot less include paths :-) + + * second, to allow external programs to effectively access + internal data fields. For example, this can be extremely + useful if someone wants to write a font producer or a font + manager on top of FreeType. + + Basically, you should now use the 'freetype/' prefix for header + inclusion, as in: + + #include <freetype/freetype.h> + #include <freetype/ftglyph.h> + + Some new include sub-directories are available: + + a. the `freetype/config' directory, contains two files used to + configure the build of the library. Client applications + should not need to look at these normally, but they can if + they want. + + #include <freetype/config/ftoption.h> + #include <freetype/config/ftconfig.h> + + b. the `freetype/internal' directory, contains header files that + describes library internals. These are the header files that + were previously found in the `src/base' and `src/shared' + directories. + + + As usual, the build system and the demos have been updated to + reflect the change.. + + Here's a layout of the new directory hierarchy: + + TOP_DIR + include/ + freetype/ + freetype.h + ... + config/ + ftoption.h + ftconfig.h + ftmodule.h + + internal/ + ftobjs.h + ftstream.h + ftcalc.h + ... + + src/ + base/ + ... + + sfnt/ + psnames/ + truetype/ + type1/ + type1z/ + + + Compiling a module is now much easier, for example, the following + should work when in the TOP_DIR directory on an ANSI build: + + gcc -c -I./include -I./src/base src/base/ftbase.c + gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c + etc.. + + (of course, using -Iconfig/<system> if you provide system-specific + configuration files). + + - updated the structure of FT_Outline_Funcs in order to allow direct + coordinate scaling within the outline decomposition routine (this + is important for virtual `on' points with TrueType outlines) + + updates to the rasters to support this.. + + - updated the OS/2 table loading code in `src/sfnt/ttload.c' in + order to support version 2 of the table (see OpenType 1.2 spec) + + - created `include/tttables.h' and `include/t1tables.h' to allow + client applications to access some of the SFNT and T1 tables of a + face with a procedural interface (see `FT_Get_Sfnt_Table') + + updates to internal source files to reflect the change.. + + - some cleanups in the source code to get rid of warnings when + compiling with the `-Wall -W -ansi -pedantic' options in gcc. + + - debugged and moved the smooth renderer to `src/base/ftgrays.c' and + its header to `include/ftgrays.h' + + - updated TT_MAX_SUBGLYPHS to 96 as some CJK fonts have composites + with up to 80 sub-glyphs !! Thanks to Werner + + +====================================================================== + +OLD CHANGES - 14-apr-2000 + + - fixed a bug in the TrueType glyph loader that prevented the + correct loading of some CJK glyphs in mingli.ttf + + - improved the standard Type 1 hinter in `src/type1' + + - fixed two bugs in the experimental Type 1 driver in `src/type1z' + to handle the new XFree86 4.0 fonts (and a few other ones..) + + - the smooth renderer is now complete and supports sub-banding to + render large glyphs at high speed. However, it is still located + in `demos/src/ftgrays.c' and should move to the library itself in + the next beta. NOTE: The smooth renderer doesn't compile in + stand-alone mode anymore, but this should be fixed RSN.. + + - introduced convenience functions to more easily deal with glyph + images, see `include/ftglyph.h' for more details, as well as the + new demo program named `demos/src/ftstring.c' that demonstrates + its use + + - implemented FT_LOAD_NO_RECURSE in both the TrueType and Type 1 + drivers (this is required by the auto-hinter to improve its + results). + + - changed the raster interface, in order to allow client + applications to provide their own span-drawing callbacks. + However, only the smooth renderer supports this. See + `FT_Raster_Params' in the file `include/ftimage.h'. + + - fixed a small bug in FT_MulFix that caused incorrect transform + computation! + + - Note: The tutorial is out-of-date. + + +====================================================================== + +OLD CHANGES - 12-mar-2000 + + - changed the layout of configuration files : now, all ANSI + configuration files are located in + `freetype2/config'. System-specific over-rides can be placed in + `freetype2/config/<system>'. + + - moved all configuration macros to `config/ftoption.h' + + - improvements in the Type 1 driver with AFM support + + - changed the fields in the FT_Outline structure : the old `flags' + array is re-named `tags', while all ancient flags are encoded into + a single unsigned int named `flags'. + + - introduced new flags in FT_Outline.flags (see + ft_outline_.... enums in `ftimage.h'). + + - changed outline functions to `FT_Outline_<action>' syntax + + - added a smooth anti-alias renderer to the demonstration programs + + - added Mac graphics driver (thanks Just) + + - FT_Open_Face changed in order to received a pointer to a + FT_Open_Args descriptor.. + + - various cleanups, a few more API functions implemented (see + FT_Attach_File) + + - updated some docs + + +====================================================================== + +OLD CHANGES - 22-feb-2000 + + - introduced the `psnames' module. It is used to: + + o convert a Postscript glyph name into the equivalent Unicode + character code (used by the Type 1 driver(s) to synthesize on + the fly a Unicode charmap). + + o provide an interface to retrieve the Postscript names of the + Macintosh, Adobe Standard & Adobe Expert character codes. + (the Macintosh names are used by the SFNT-module postscript + names support routines, while the other two tables are used by + the Type 1 driver(s)). + + - introduced the `type1z' alternate Type 1 driver. This is a (still + experimental) driver for the Type 1 format that will ultimately + replace the one in `src/type1'. It uses pattern matching to load + data from the font, instead of a finite state analyzer. It works + much better than the `old' driver with `broken' fonts. It is also + much smaller (under 15 Kb). + + - the Type 1 drivers (both in `src/type1' and `src/type1z') are + nearly complete. They both provide automatic Unicode charmap + synthesis through the `psnames' module. No re-encoding vector is + needed. (note that they still leak memory due to some code + missing, and I'm getting lazy). + + Trivial AFM support has been added to read kerning information but + wasn't exactly tested as it should ;-) + + - The TrueType glyph loader has been seriously rewritten (see the + file `src/truetype/ttgload.c'. It is now much, much simpler as + well as easier to read, maintain and understand :-) Preliminary + versions introduced a memory leak that has been reported by Jack + Davis, and is now fixed.. + + - introduced the new `ft_glyph_format_plotter', used to represent + stroked outlines like Windows `Vector' fonts, and certain Type 1 + fonts like `Hershey'. The corresponding raster will be written + soon. + + - FT_New_Memory_Face is gone. Likewise, FT_Open_Face has a new + interface that uses a structure to describe the input stream, the + driver (if required), etc.. + + +TODO + + - Write FT_Get_Glyph_Bitmap and FT_Load_Glyph_Bitmap + + - Add a function like FT_Load_Character(face, char_code, load_flags) + that would really embed a call to FT_Get_Char_Index then + FT_Load_Glyph to ease developer's work. + + - Update the tutorial! + + - consider adding support for Multiple Master fonts in the Type 1 + drivers. + + - Test the AFM routines of the Type 1 drivers to check that kerning + information is returned correctly. + + - write a decent auto-gridding component !! We need this to release + FreeType 2.0 gold ! + + +less urgent needs: + + - add a CFF/Type2 driver + - add a BDF driver + - add a FNT/PCF/HBF driver + - add a Speedo driver from the X11 sources + + +====================================================================== + +OLDER CHANGES - 27-jan-2000 + + - updated the `sfnt' module interface to allow several SFNT-based + drivers to co-exist peacefully + + - updated the `T1_Face' type to better separate Postscript font + content from the rest of the FT_Face structure. Might be used + later by the CFF/Type2 driver.. + + - added an experimental replacement Type 1 driver featuring advanced + (and speedy) pattern matching to retrieve the data from postscript + fonts. + + - very minor changes in the implementation of FT_Set_Char_Size and + FT_Set_Pixel_Sizes (they now implement default to lighten the font + driver's code). + + +====================================================================== + +OLD MESSAGE + +This file summarizes the changes that occurred since the last `beta' +of FreeType 2. Because the list is important, it has been divided into +separate sections: + +Table Of Contents: + + I High-Level Interface (easier !) + II Directory Structure + III Glyph Image Formats + IV Build System + V Portability + VI Font Drivers + + +---------------------------------------------------------------------- + +High-Level Interface: + + The high-level API has been considerably simplified. Here is how: + + - resource objects have disappeared. this means that face objects + can now be created with a single function call (see FT_New_Face + and FT_Open_Face) + + - when calling either FT_New_Face & FT_Open_Face, a size object + and a glyph slot object are automatically created for the face, + and can be accessed through `face->glyph' and `face->size' if + one really needs to. In most cases, there's no need to call + FT_New_Size or FT_New_Glyph. + + - similarly, FT_Load_Glyph now only takes a `face' argument + (instead of a glyph slot and a size). Also, its `result' + parameter is gone, as the glyph image type is returned in the + field `face->glyph.format' + + - the list of available charmaps is directly accessible through + `face->charmaps', counting `face->num_charmaps' elements. Each + charmap has an 'encoding' field which specifies which known + encoding it deals with. Valid values are, for example: + + ft_encoding_unicode (for ASCII, Latin-1 and Unicode) + ft_encoding_apple_roman + ft_encoding_sjis + ft_encoding_adobe_standard + ft_encoding_adobe_expert + + other values may be added in the future. Each charmap still + holds its `platform_id' and `encoding_id' values in case the + encoding is too exotic for the current library + + +---------------------------------------------------------------------- + +Directory Structure: + + Should seem obvious to most of you: + + freetype/ + config/ -- configuration sub-makefiles + ansi/ + unix/ -- platform-specific configuration files + win32/ + os2/ + msdos/ + + include/ -- public header files, those to be included + directly by client apps + + src/ -- sources of the library + base/ -- the base layer + sfnt/ -- the sfnt `driver' (see the drivers section + below) + truetype/ -- the truetype driver + type1/ -- the type1 driver + shared/ -- some header files shared between drivers + + demos/ -- demos/tools + + docs/ -- documentation (a bit empty for now) + + +---------------------------------------------------------------------- + +Glyph Image Formats: + + Drivers are now able to register new glyph image formats within the + library. For now, the base layer supports of course bitmaps and + vector outlines, but one could imagine something different like + colored bitmaps, bi-color vectors or whatever else (Metafonts anyone + ??). + + See the file `include/ftimage.h'. Note also that the type + FT_Raster_Map is gone, and is now replaced by FT_Bitmap, which + should encompass all known bitmap types. + + Each new image format must provide at least one `raster', i.e. a + module capable of transforming the glyph image into a bitmap. It's + also possible to change the default raster used for a given glyph + image format. + + The default outline scan-converter now uses 128 levels of grays by + default, which tends to smooth many things. Note that the demo + programs have been updated significantly in order to display these.. + + +---------------------------------------------------------------------- + +Build system: + + You still need GNU Make to build the library. The build system has + been very seriously re-vamped in order to provide things like : + + - automatic host platform detection (reverting to 'config/ansi' if + it is not detected, with pseudo-standard compilation flags) + + - the ability to compile from the Makefiles with very different and + exotic compilers. Note that linking the library can be difficult + for some platforms. + + For example, the file `config/win32/lcclib.bat' is invoked by the + build system to create the `.lib' file with LCC-Win32 because its + librarian has too many flaws to be invoked directly from the + Makefile. + + Here's how it works: + + - the first time you type `make', the build system runs a series of + sub-makefiles in order to detect your host platform. It then + dumps what it found, and creates a file called `config.mk' in the + current directory. This is a sub-Makefile used to define many + important Make variables used to build the library. + + - the second time, the build system detects the `config.mk' then use + it to build the library. All object files go into 'obj' by + default, as well as the library file, but this can easily be + changed. + + Note that you can run `make setup' to force another host platform + detection even if a `config.mk' is present in the current + directory. Another solution is simply to delete the file, then + re-run make. + + Finally, the default compiler for all platforms is gcc (for now, + this will hopefully changed in the future). You can however specify + a different compiler by specifying it after the 'setup' target as + in: + + gnumake setup lcc on Win32 to use the LCC compiler + gnumake setup visualc on Win32 to use Visual C++ + + See the file `config/<system>/detect.mk' for a list of supported + compilers for your platforms. + + It should be relatively easy to write new detection rules files and + config.mk.. + + Finally, to build the demo programs, go to `demos' and launch GNU + Make, it will use the `config.mk' in the top directory to build the + test programs.. + + +---------------------------------------------------------------------- + +Portability: + + In the previous beta, a single FT_System object was used to + encompass all low-level operations like thread synchronisation, + memory management and i/o access. This has been greatly simplified: + + - thread synchronisation has been dropped, for the simple reason + that the library is already re-entrant, and that if you really + need two threads accessing the same FT_Library, you should + really synchronize access to it yourself with a simple mutex. + + - memory management is performed through a very simple object + called `FT_Memory', which really is a table containing a table + of pointers to functions like malloc, realloc and free as well + as some user data (closure). + + - resources have disappeared (they created more problems than they + solved), and i/o management have been simplified greatly as a + result. Streams are defined through FT_Stream objects, which + can be either memory-based or disk-based. + + Note that each face has its own stream, which is closed only + when the face object is destroyed. Hence, a function like + TT_Flush_Face in 1.x cannot be directly supported. However, if + you really need something like this, you can easily tailor your + own streams to achieve the same feature at a lower level (and + use FT_Open_Face instead of FT_New_Face to create the face). + + See the file `include/ftsystem.h' for more details, as well as the + implementations found in `config/unix' and `config/ansi'. + + +---------------------------------------------------------------------- + +Font Drivers: + + The Font Driver interface has been modified in order to support + extensions & versioning. + + + The list of the font drivers that are statically linked to the + library at compile time is managed through a new configuration file + called `config/<platform>/ftmodule.h'. + + This file is autogenerated when invoking `make modules'. This + target will parse all sub-directories of 'src', looking for a + `module.mk' rules file, used to describe the driver to the build + system. + + Hence, one should call `make modules' each time a font driver is + added or removed from the `src' directory. + + Finally, this version provides a `pseudo-driver' in `src/sfnt'. + This driver doesn't support font files directly, but provides + services used by all TrueType-like font drivers. Hence, its code is + shared between the TrueType & OpenType font formats, and possibly + more formats to come if we're lucky.. + + +---------------------------------------------------------------------- + +Extensions support: + + The extensions support is inspired by the one found in 1.x. + + Now, each font driver has its own `extension registry', which lists + which extensions are available for the font faces managed by the + driver. + + Extension ids are now strings, rather than 4-byte tags, as this is + usually more readable. + + Each extension has: + - some data, associated to each face object + - an interface (table of function pointers) + + An extension that is format-specific should simply register itself + to the correct font driver. Here is some example code: + + // Registering an extensions + // + FT_Error FT_Init_XXXX_Extension( FT_Library library ) + { + FT_DriverInterface* tt_driver; + + driver = FT_Get_Driver( library, "truetype" ); + if (!driver) return FT_Err_Unimplemented_Feature; + + return FT_Register_Extension( driver, &extension_class ); + } + + + // Implementing the extensions + // + FT_Error FT_Proceed_Extension_XXX( FT_Face face ) + { + FT_XXX_Extension ext; + FT_XXX_Extension_Interface ext_interface; + + ext = FT_Get_Extension( face, "extensionid", &ext_interface ); + if (!ext) return error; + + return ext_interface->do_it(ext); + } + +------------------------------------------------------------------------ + +Copyright 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 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.

Configuration macros + + The file found in `include/freetype/config/ftoption.h' contains a + list of commented configuration macros that can be toggled by + developers to indicate which features should be active while + building the library. + + These options range from debug level to availability of certain + features, like native TrueType hinting through a bytecode + interpreter. + + We invite you to read this file for more information. You can + change the file's content to suit your needs, or override it with + one of the techniques described below. + + +II. Modules list + + If you use GNU make please edit the top-level file `modules.cfg'. + It contains a list of available FreeType modules and extensions to + be compiled. Change it to suit your own preferences. Be aware that + certain modules depend on others, as described in the file. GNU + make uses `modules.cfg' to generate `ftmodule.h' (in the object + directory). + + If you don't use GNU make you have to manually edit the file + `include/freetype/config/ftmodule.h' (which is *not* used with if + compiled with GNU make) to add or remove the drivers and components + you want to compile into the library. See `INSTALL.ANY' for more + information. + + +III. System interface + + FreeType's default interface to the system (i.e., the parts that + deal with memory management and i/o streams) is located in + `src/base/ftsystem.c'. + + The current implementation uses standard C library calls to manage + memory and to read font files. It is however possible to write + custom implementations to suit specific systems. + + To tell the GNU Make-based build system to use a custom system + interface, you have to define the environment variable FTSYS_SRC to + point to the relevant implementation: + + on Unix: + + ./configure <your options> + export FTSYS_SRC=foo/my_ftsystem.c + make + make install + + on Windows: + + make setup <compiler> + 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 `<topdir>/objs'), which GNU make prefers over the + standard location. No action is needed for `ftmodule.h' because + it is generated automatically in the objects directory. + + + 2. Using the C include path + + Use the C include path to ensure that your own versions of the + files are used at compile time when the lines + + #include FT_CONFIG_OPTIONS_H + #include FT_CONFIG_MODULES_H + + are compiled. Their default values being + <freetype/config/ftoption.h> and <freetype/config/ftmodule.h>, 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.

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'. + + 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 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.

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

Before reading this document, please consult +INSTALL.UNIX for required tools and the basic self-building procedure. + + + 1. Required Tools + ----------------- + + For self-building the FreeType library on a Unix system, GNU Make + 3.80 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=<system>' and + `--build=<system>' 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=<system>' 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 + + or + + env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure + + 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=<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. In such + cases, the make variable `DESTDIR' is useful to change the root + directory in the installation. For example, after + + make DESTDIR=/mnt/target_system_root/ install + + the built FreeType2 library files are installed into the directory + `/mnt/target_system_root/<prefix_in_configure>/lib'. + + + 5.

Determine the correct installation path + ------------------------------------------ + + By default, the configure script installs the library in + `/usr/local'. However, many Unix distributions now install the + library in `/usr', since FreeType is becoming a critical system + component. + + If FreeType is already installed on your system, type + + freetype-config --prefix + + on the command line.

If this happens, install GNU Make + on your system, and use the GNUMAKE environment variable to name it. + + + 4. Build and install the library + -------------------------------- + + The following should work on all Unix systems where the `make' + command invokes GNU Make: + + ./configure --prefix=<yourprefix> + make + make install (as root) + + where `<yourprefix>' must be replaced by the prefix returned by the + `freetype-config' command. + + When using a different command to invoke GNU Make, use the GNUMAKE + variable.

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.

This implies the following scheme:</p> +<p>First, available or installed font faces are uniquely identified by <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> 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.</p> +<p>Second, the cache calls, only when needed, a client-provided function to convert a <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> into a new <a href="ft2-base_interface.html#FT_Face">FT_Face</a> object. The latter is then completely managed by the cache, including its termination through <a href="ft2-base_interface.html#FT_Done_Face">FT_Done_Face</a>.</p> +<p>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 <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a>. However, more complex schemes are also possible.</p> +<p>Note that for the cache to work correctly, the face ID values must be <b>persistent</b>, which means that the contents they point to should not change at runtime, or that their value should not become invalid.</p> +<p>If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call <a href="ft2-cache_subsystem.html#FTC_Manager_RemoveFaceID">FTC_Manager_RemoveFaceID</a> as soon as possible, to let the cache get rid of any references to the old <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.</p> +<p>To use the cache, start with calling <a href="ft2-cache_subsystem.html#FTC_Manager_New">FTC_Manager_New</a> to create a new <a href="ft2-cache_subsystem.html#FTC_Manager">FTC_Manager</a> object, which models a single cache instance. You can then look up <a href="ft2-base_interface.html#FT_Face">FT_Face</a> and <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects with <a href="ft2-cache_subsystem.html#FTC_Manager_LookupFace">FTC_Manager_LookupFace</a> and <a href="ft2-cache_subsystem.html#FTC_Manager_LookupSize">FTC_Manager_LookupSize</a>, respectively.</p> +<p>If you want to use the charmap caching, call <a href="ft2-cache_subsystem.html#FTC_CMapCache_New">FTC_CMapCache_New</a>, then later use <a href="ft2-cache_subsystem.html#FTC_CMapCache_Lookup">FTC_CMapCache_Lookup</a> to perform the equivalent of <a href="ft2-base_interface.html#FT_Get_Char_Index">FT_Get_Char_Index</a>, only much faster.</p> +<p>If you want to use the <a href="ft2-glyph_management.html#FT_Glyph">FT_Glyph</a> caching, call <a href="ft2-cache_subsystem.html#FTC_ImageCache">FTC_ImageCache</a>, then later use <a href="ft2-cache_subsystem.html#FTC_ImageCache_Lookup">FTC_ImageCache_Lookup</a> to retrieve the corresponding <a href="ft2-glyph_management.html#FT_Glyph">FT_Glyph</a> objects from the cache.</p> +<p>If you need lots of small bitmaps, it is much more memory efficient to call <a href="ft2-cache_subsystem.html#FTC_SBitCache_New">FTC_SBitCache_New</a> followed by <a href="ft2-cache_subsystem.html#FTC_SBitCache_Lookup">FTC_SBitCache_Lookup</a>.
