Scan for `/sfnts' token. 2007-01-07 Werner Lemberg * src/cid/cidparse.c (cid_parser_new): Reject Type 11 fonts. 2007-01-06 Werner Lemberg * src/cff/cffload.c (cff_index_init): Remove unused variable. (cff_index_read_offset): s/perror/errorp/ to avoid global shadowing. 2007-01-04 David Turner * src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts correctly. This fixes Savannah bug #17876. Do not allocate interpreter-specific tables in memory if we are not going to load glyphs with the bytecode interpreter anyway. * src/truetype/ttgload.c (tt_loader_init): Load execution context only if glyph is hinted. Updated. * src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready' and `cvs_ready'. Add `tt_size_ready_bytecode' declaration. * src/truetype/ttobjs.c (tt_size_done_bytecode, tt_size_init_bytecode, tt_size_ready_bytecode): New functions. (tt_size_init): Move most code into `tt_size_init_bytecode'. (tt_size_done): Move most code into `tt_size_done_bytecode'. (tt_size_reset): Move some code to `tt_size_ready_bytecode'. Don't extract the metrics table from the SFNT font file. Instead, reparse it on each glyph load. The runtime difference is not noticeable, and it can save a lot of heap memory when memory-mapped files are not used. * include/freetype/internal/tttypes.h (TT_FaceRec): Add members `horz_metrics_offset' and `vert_metrics_ofset'. * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Updated. * src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization. Do not load the CFF index offsets into memory, since this wastes a *lot* of heap memory with large Asian CFF fonts. There is no significant performance loss. * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration. * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and `data_size'. (CFF_CharsetRec): Add field `num_glyphs'. * src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets, cff_charset_cid_to_gindex): New functions. (cff_new_index): Renamed to... (cff_index_init): This. Update all callers. Updated -- some code has been moved to `cff_index_load_offsets'. (cff_done_index): Renamed to... (cff_index_done): This. Update all callers. (cff_index_get_pointers, cff_index_access_element): Updated to use stream offsets. (cff_charset_compute_cids): Set `num_glyphs' field. (cff_encoding_load): Updated. * src/cff/cffgload.c (cff_slot_load): Updated. 2007-01-04 David Turner * docs/INSTALL.UNIX: Simplify some parts, add reference to autogen.sh and pointer to README.CVS. * README.CVS: Add common problem description and solution when running autogen.sh. * docs/INSTALL: Add reference to MacOS X. * docs/MAKEPP, docs/INSTALL.MAC: New documentation files. * docs/TODO: Remove obsolete items. * src/raster/ftraster.c: (TRaster_Instance): Replace it with... (TWorker): This. Remove `count_table' and `memory'. Make `grays' a pointer. (TRaster): New structure. (count_table): New static array. (RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras, Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done, ft_black_set_mode, ft_black_render): Updated. (ft_black_init): Don't initialize `count_table'. (ft_black_reset): Use the render pool. This saves about 6KB of heap space for each FT_Library instance. * src/smooth/ftgrays.c (TRaster): Replaced with... (TWorker): This. Remove `memory'. (TRaster): New structure. (RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line, gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to, gray_render_span, gray_raster_render): Updated. (gray_raster_reset): Use the render pool. This saves about 6KB of heap space for each FT_Library instance. * src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h, src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since the optimization is no longer experimental. * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points): Remove a typo that results in no hinting and a memory leak with some large Asian CFF fonts. * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak which happens when FT_Done_Library is called with still opened CFF_Faces in it. We need to close all faces before destroying the modules, or else some bad things (memory leaks) may happen. 2007-01-02 Werner Lemberg * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): Remove compiler warning. 2007-01-02 David Turner * src/sfnt/sfobjs.c: Add documentation comment. 2006-12-31 Masatake YAMATO * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New function. Check uniqueness of the gid pairs. (gxv_kern_subtable_fmt0_validate): Move some code to `gxv_kern_subtable_fmt0_pairs_validate'. 2006-12-22 David Turner * src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler warnings. * builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE to avoid deprecation warnings with Visual C++ 8. 2006-12-16 Anders Kaseorg * src/base/ftlcdfil.c (FT_Library_SetLcdFilter) [FT_FORCE_LIGHT_LCD_FILTER]: Fix typo. 2006-12-15 suzuki toshiya * include/freetype/internal/services/svotval.h: Add `volatile' to sync with the modification by Jens Claudius on 2006-08-22; cf. http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5 2006-12-15 suzuki toshiya * src/base/ftmac.c: Specialized for Mac OS X only. * builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework. * builds/unix/configure.raw: Ditto. When explicit switches for FSSpec/FSRef/QuickDraw/ATS availability are given to configure, builds/mac/ftmac.c is used instead of default src/base/ftmac.c. 2006-12-15 suzuki toshiya * builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system. * builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c instead of src/base/ftmac.c * builds/mac/FreeType.ppc_carbon.make.txt: Ditto. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. * builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c that cannot be built at present. 2006-12-15 suzuki toshiya * src/base/ftobjs.c: Improvement of resource fork handler for POSIX, cf. http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html (Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font format or .dfont, to simulate the face index number counted by ftmac.c. (IsMacResource): Return the number of scalable faces correctly. 2006-12-10 Werner Lemberg * builds/toplevel.mk (version): Protect against `distclean' target. 2006-12-09 Werner Lemberg * builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat' or `type'. * builds/freetype.mk (version): Extracted from freetype.h, using GNU make's built-in string functions. (refdoc): Use $(version) instead of static version number. 2006-12-08 Werner Lemberg * builds/toplevel.mk (dist): Extract version number from freetype.h. 2006-12-08 Vladimir Volovich * src/tools/apinames (State): Remove final comma in structure -- xlc v5 under AIX 4.3 doesn't like this. 2006-12-07 David Turner * src/autofit/afloader.c (af_loader_load_g): Small adjustment to the spacing of auto-fitted glyphs. This only impacts rare cases (e.g., Arial Bold at rather small character sizes). 2006-12-03 Werner Lemberg * src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c. 2006-12-01 Werner Lemberg * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are encoded in UTF-16BE. Patch from Rajeev Pahuja . (tt_name_entry_ascii_from_ucs4): Removed. * include/freetype/ftxf86.h: Fix and extend comment so that it appears in the documentation. * include/freetype/ftchapters.h: Add `font_format' section. * src/tools/docmaker/tohtml.py (HtmlFormatter::index_exit): Add link to TOC in index page. 2006-11-28 David Turner * src/smooth/ftgrays.c (gray_raster_render): Return 0 when we are trying to render into a zero-width/height bitmap, not an error code. * src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch. * src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType ones instead. * src/autofit/afhints.c (af_glyph_hints_dump_segments): Remove unused variable. 2006-11-26 Pierre Hanser * src/truetype/ttobjs.c (tt_face_init): Protect against NULL pointer. 2006-11-25 David Turner * src/autofit/afhints.c (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]: Add stubs to link the `ftgrid' test program when debugging is disabled in the auto-hinter. 2006-11-23 David Turner * src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c, src/autofit/aftypes.h: Miscellaneous auto-hinter improvements. * src/autofit/afhints.c (af_glyph_hints_dump_segments) [AF_DEBUG]: Emit more sensible information. * src/autofit/afhints.h (AF_SegmentRec): Add `height' member. * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Improve rounding of blue values. (af_latin_hints_compute_segments): Hint segment heights. (af_latin_hints_link_segments): Reduce `len_score' value.

Use correct constant for comparison to get `exec->grayscale'. 2006-11-18 Werner Lemberg Because FT_Load_Glyph expects CID values for CID-keyed fonts, the test for a valid glyph index must be deferred to the font drivers. This patch fixes Savannah bug #18301. * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c (FNT_Load_Glyph): Check validity of `glyph_index'. 2006-11-13 David Turner * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine. The interpreter `enhancements' are still too buggy for general use. * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros when building the library to change the default LCD filter to be used. This is only useful for experimentation. * include/freetype/ftlcdfil.h: Update documentation. 2006-11-10 David Turner * src/smooth/ftsmooth.c: API change for the LCD filter. The FT_LcdFilter value is an enumeration describing which filter to apply, with new values FT_LCD_FILTER_LIGHT and FT_LCD_FILTER_LEGACY (the latter implements the LibXft original algorithm which produces strong color fringes for everything except very-well hinted text). * include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change second parameter to an enum type. * src/base/ftlcdfil.c (USE_LEGACY): Define. (_ft_lcd_filter): Rename to... (_ft_lcd_filter_fir): This. Update parameters. (_ft_lcd_filter_legacy) [USE_LEGACY]: New filter function. (FT_Library_Set_LcdFilter): Update parameters. Handle new filter modes. * include/internal/ftobjs.h: Include FT_LCD_FILTER_H. (FT_Bitmap_LcdFilterFunc): Change third argument to `FT_Library'.

Other minor improvements. * src/autofit/aflatin.c: Various tiny improvements that drastically improve the handling of serif fonts and of LCD/LCD_V hinting modes. (af_latin_hints_compute_edges): Fix typo. (af_latin_compute_stem_width): Take better care of diagonal stems. 2006-11-09 David Turner * src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix typo which created a variable-used-before-initialized bug. 2006-11-07 Zhe Su * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout also. 2006-11-03 Werner Lemberg * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'. 2006-11-02 David Turner Add a few tweaks to better handle serif fonts. Add more debugging messages. * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore segments that are less than 1.5 pixels high. This gets rid of *many* corner cases with serifs. (af_latin_align_linked_edge): Add logging message. (af_latin_hint_edges): Use AF_HINTS_DO_BLUES. Add logging messages. Handle AF_EDGE_FLAG flag specially. * src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug, _af_debug_disable_blue_hints, and _af_debug_hints variables. * src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug. Update external declarations. (af_corner_orientation, af_corner_is_flat): Replaced by... * include/freetype/internal/ftcalc.h (ft_corner_orientation, ft_corner_is_flat): These declarations. * src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat): Comment out. Replaced by... * src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat): These functions. Update all callers. (FT_Add64) [!FT_LONG64]: Simplify. * src/autofit/afhints.c: Include FT_INTERNAL_CALC_H. (af_direction_compute): Add a missing FT_ABS call. This bug caused production of garbage by missing lots of segments. * src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro. * src/autofit/afloader.c (af_loader_init, af_loader_done) [AF_DEBUG]: Set _af_debug_hints. * src/pshinter/pshalgo.c: Include FT_INTERNAL_CALC_H. (psh_corner_is_flat, psh_corner_orientation): Use ft_corner_is_flat and ft_corner_orientation. * src/gzip/inftrees.c (huft_build): Remove compiler warning. 2006-10-24 Werner Lemberg * src/cff/cffload.c (cff_encoding_load): Remove unused variable. * src/base/ftobjs.c (FT_Select_Charmap): Disallow FT_ENCODING_NONE as argument. 2006-10-23 Zhe Su * src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to better deal with broken Asian fonts with strange glyphs, having self-intersections and other peculiarities. The used algorithm is based on the nonzero winding rule. 2006-10-23 David Turner Speed up the CFF font loader. With some large CFF fonts, FT_Open_Face is now more than three times faster. * src/cff/cffload.c (cff_get_offset): Removed. (cff_new_index): Inline functionality of `cff_get_offset'. (cff_charset_compute_cids, cff_charset_free_cids): New functions. (cff_charset_done): Call `cff_charset_free_cids'. (cff_charset_load): Call `cff_charset_compute_cids'. (cff_encoding_load) : Ditto, to replace inefficient loop. * src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX with FT_NEXT_XXX. Speed up the Postscript hinter, with more than 100% speed increase on my machine. * src/pshinter/pshalgo.c (psh_corner_is_flat, psh_corner_orientation): New functions. (psh_glyph_compute_inflections): Merge loops for efficiency. Use `psh_corner_orientation'. (psh_glyph_init): Use `psh_corner_is_flat'. (psh_hint_table_find_strong_point): Renamed to... (psh_hint_table_find_strong_points): This. Rewrite, adding argument to handle all points at once. Update all callers. (PSH_MAX_STRONG_INTERNAL): New macro.

Also suffix for target executable is passed by EXEEXT. * builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to build `apinames' which runs on building system. They are set by CC_BUILD and EXEEXT_BUILD. * builds/exports.mk (APINAMES_EXE): Change the extension for apinames from the suffix for target (E) to that for building host (E_BUILD). 2006-10-12 Werner Lemberg * docs/INSTALL.UNX, docs/UPGRADE.UNX: Renamed to... * docs/INSTALL.UNIX, docs/UPGRADE.UNIX: This. Update all documents which reference those files. 2006-10-12 suzuki toshiya * builds/unix/configure.raw (FT2_EXTRA_LIBS): New variable. It is embedded in freetype2.pc and freetype-config. Use it to record Carbon dependency of MacOSX. * builds/unix/freetype2.in: Embed FT2_EXTRA_LIBS. * builds/unix/freetype-config.in: Ditto. 2006-10-11 Werner Lemberg * devel/ftoption.h (FT_CONFIG_OPTION_SUBPIXEL_RENDERING): Define for development. 2006-10-03 Jens Claudius * include/freetype/config/ftstdlib.h: Cast away volatileness from argument to ft_setjmp. * include/freetype/internal/ftvalid.h: Add comment that ft_validator_run must not be used. 2006-10-01 Werner Lemberg * src/base/ftbase.c: Undo change from 2006-09-30. * src/base/rules.mk (BASE_SRC): Remove `ftlcdfil.c'. 2006-09-30 David Turner * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): s/unpatented_hinting/ignore_unpatented_hinter/. Update all callers. * src/base/ftobjs.c (FT_Load_Glyph): Refine the algorithm whether auto-hinting shall be used or not. * src/truetype/ttobjs.c (tt_face_init): Ditto. 2006-09-30 Werner Lemberg * src/base/rules.mk (BASE_SRC): Remove `ftapi.c' (which is no longer in use). * src/base/ftbase.c: Include `ftlcdfil.c'. 2006-09-29 Werner Lemberg * src/sfnt/ttcmap.c (tt_cmap4_char_map_binary): Fix algorithm for overlapping segments. Bug reported by Stefan Koch. 2006-09-28 David Turner Fix a bug in the automatic unpatented hinting support which prevents normal bytecode hinting to work properly. * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): s/force_autohint/unpatented_hinting/. Update all callers. * src/base/ftobjs.c (FT_Load_Glyph): Updated code. * src/autofit/aftypes.h (AF_DEBUG): Undefine to get rid of traces. 2006-09-27 David Turner * include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2. Add a new API to support color filtering of subpixel glyph bitmaps. In a default build, the function `FT_Library_SetLcdFilter' returns `FT_Err_Unimplemented_Feature'; you need to #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the real implementation. * include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files. * include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New typedef.

This fixes Savannah bug #16914. 2006-06-26 Jens Claudius * src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15. (t1_decoder_parse_charstrings): Operator with opcode 15 pops its two arguments. Handle the case where the pops of an othersubr may be part of a subroutine. Handle unknown othersubrs gracefully: count their operands and let the following pop operators push the operands as the results onto the Type1 stack. Improve handling of setcurrentpoint opcode. 2006-06-25 Jens Claudius The Type 1 parser now skips over top-level procedures as required for a `Simplified Parser'. This makes the parser more robust as it doesn't poke around in PostScript code.

(T1_Read_Metrics): Fix memory leak which happened when the metrics file doesn't have kerning pairs. This fixes Savannah bug #16768. 2006-06-06 David Turner Fix memory leak described in Savannah bug #16759. We change `ps_unicodes_init' so that it also takes a `free_glyph_name' callback to release the glyph names returned by `get_glyph_name' * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc): Renamed to ...

This fixes Savannah bug #16669. * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation of `face->num_glyphs' which missed the last glyph, due to the offset-by-1 computation, since the PFR format doesn't guarantee that glyph index 0 corresponds to the `missing glyph. This fixes Savannah bug #16668. 2006-05-25 Werner Lemberg * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out `-no-undefined'. Reported by Christian Biesinger. 2006-05-19 Brian Weed * builds/win32/visualc/freetype.dsp: Release libraries no longer have debug information, and debug libraries use `C7 compatible' debug info. 2006-05-19 suzuki toshiya Apply patch by Derek Clegg to fix two memory leaks in the MacOS resource fork handler.

This fixes the second part of Savannah bug #16590. 2006-05-18 Werner Lemberg * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again. 2006-05-17 David Turner This is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glyph vectors themselves and the auto-fitter module. We now use inline assembler code with GCC to implement `FT_MulFix', which is probably the most important function related to the engine's performance. The resulting speed-up is about 25%. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields `cursor' and `limit'. * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation): New functions.

Update handling of re_italic and re_bold. 2006-05-11 Masatake YAMATO * builds/unix/ftsystem.c (FT_Stream_Open): Check errno only if read system call returns -1. Remove a redundant parenthesis. 2006-05-10 Werner Lemberg * builds/unix/ftsystem.c (FT_Stream_Open): Avoid infinite loop if given an empty, un-mmap()able file. Reported and suggested fix in Savannah bug #16555. * builds/freetype.mk (refdoc): Write-protect the `docmaker' directory to suppress generation of .pyc files. According to the Python docs there isn't a more elegant solution (currently). * builds/toplevel.mk (dist): New target which builds .tar.gz, .tar.bz2, and .zip files. Note that the version number is still hard-coded. (do-dist): Sub-target of `dist'. (CONFIG_GUESS, CONFIG_SUB): New variables. (.PHONY): Updated. 2006-05-09 Rajeev Pahuja * builds/win32/visualc/freetype.sln, builds/win32/visualc/freetype.vcproj: Upgraded to VS.NET 2005 from VS.NET 2003 Added files ftbbox.c, fttype1.c, ftwinfnt.c, ftsynth.c. * builds/win32/visualc/index.html: Updated. 2006-05-07 Werner Lemberg Put version information into the configure script. Reported by Paul Watson . * builds/unix/configure.ac: Renamed to... * builds/unix/configure.raw: This which now serves (with appropriate modifications) as a template for configure.ac. * version.sed: New script. * autogen.sh: Generate configure.ac from configure.raw, using FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH from freetype.h. 2006-05-06 Werner Lemberg * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.ac (version_info): Set to 9:10:3. * builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/freetype.mk (refdoc), Jamfile (RefDoc), README: s/220/221/, s/2.2.0/2.2.1/. Minor updates. * docs/CHANGES, docs/VERSION.DLL, docs/PROBLEMS, README.CVS: Updated. * builds/unix/install-sh: Updated from `texinfo' CVS module at savannah.gnu.org. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. 2006-05-04 Werner Lemberg * src/lzw/ftlzw2.c: Renamed to... * src/lzw/ftlzw.c: This. * src/lzw/Jamfile, src/lzw/rules.mk: Updated. * builds/mac/FreeType.m68k_cfm.make.txt, builds/mac/FreeType.m68k_far.make.txt, builds/mac/FreeType.ppc_carbon.make.txt, builds/mac/FreeType.ppc_classic.make.txt: Updated. 2006-05-03 David Turner Allow compilation again with C++ compilers. * include/freetype/internal/ftmemory.h (FT_ASSIGNP, FT_ASSIGNP_INNER): New macros which do the actual assignment, and which exist in two variants (for C and C++). Update callers accordingly. 2006-05-03 Werner Lemberg * include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed. 2006-05-02 Werner Lemberg * include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++). (FT_ALLOC): Remove redundant redefinition. * builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use `-Wstrict-prototypes'. * src/base/ftstream.c (FT_Stream_EnterFrame): Add cast. * include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]: Remove `extern'. 2006-05-02 David Turner Update the memory management functions and macros to safely deal with array size buffer overflows. This corresponds to attemps to allocate arrays that are too large. For an example, consider the following code: count = read_uint32_from_file(); array = malloc( sizeof ( Item ) * count ); for ( nn = 0; nn < count; nn++ ) array[nn] = read_item_from_file(); If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the multiplication overflows, and the array allocated os smaller than the data read from the file. In this case, the heap will be trashed, and this can be used as a denial-of-service attack, or make the engine crash later. The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new count is no larger than `FT_INT_MAX/item_size', otherwise a new error code `FT_Err_Array_Too_Large' will be returned. Note that the memory debugger now works again when FT_DEBUG_MEMORY is defined. FT_STRICT_ALIASING has disappeared; the corresponding code is now the default. * include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]: Don't use `extern'. * include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error code. * include/freetype/internal/ftmemory.h (FT_DEBUG_INNER) [FT_DEBUG_MEMORY]: New macro.

(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc. (FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free. 2006-04-30 suzuki toshiya * src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos initialization, remove extra cast to copy to pfb_lenpos. This fixes parsing of PFB fonts with MacOS resource fork (bug introduced 2003-09-11). Patch provided by Huib-Jan Imbens . 2006-04-29 Werner Lemberg Further C library abstraction.

Update declarations according to the changes in the corresponding source files. Note that these files are not used by FreeType clients; all public APIs of the cache module have been already moved to `include/freetype/ftcache.h', and all FT_CACHE_INTERNAL_XXXX_H macros resolve to it. Reason for the move is to allow modifications of the internals without interferences with rogue clients. Note that there are no known clients that access the cache internals at the moment. * builds/unix/install.mk (install): Don't install headers from $(CACHE_H).

(FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New compatibility code. * src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to support rogue clients compiled against 2.1.7 to work correctly. This probably explains the GNUstep crashes with the second release candidate. 2006-02-23 Chia-I Wu * include/freetype/ftoutln.h (enum FT_Orientation): New value `FT_ORIENTATION_NONE'. * src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has, ft_contour_enclosed, ft_outline_get_orientation): Another version of `FT_Outline_Get_Orientation'. This version differs from the public one in that each part (contour not enclosed in another contour) of the outline is checked for orientation. (FT_Outline_Embolden): Use `ft_outline_get_orientation'. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and use bitmap's embolden routine when the outline one failed. 2006-02-22 Chia-I Wu * modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI compatibility. * src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit loading.

Note that this change unfortunately prevents memory optimizations for the embedded bitmap loader. * include/freetype/internal/sfnt.h (SFNT_Interface): Move `set_sbit_strike' and `load_sbit_metrics' fields to the location of version 2.1.8. * src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call FT_Size_Request. (sfnt_interface): Updated. * src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load ttsbit0.c. (tt_load_sbit_metrics): Make `sbit_small_metrics_fields' static. * src/sfnt/ttsbit.h: Updated. 2006-02-17 David Turner * builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported functions anymore. This ensures that all FT_BASE internal functions are available for dynamic linking. * include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE, FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec, FTC_OldImageDescRec, FTC_ImageCache_Lookup, FTC_Image_Cache_New, FTC_OldImage_Desc, FTC_OLD_IMAGE_FORMAT, ftc_old_image_xxx, ftc_image_type_from_old_desc, FTC_Image_Cache_Lookup, FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the cache sub-system. We try to recognize old legacy signatures with a gross hack (hope it works). 2006-02-17 Werner Lemberg * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. 2006-02-16 David Turner Massive changes to the internals to respect the internal object layouts and exported functions of FreeType 2.1.7. Note that the cache sub-system cannot be fully retrofitted, unfortunately. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_OLD_INTERNALS): New macro. * include/freetype/ftcache.h, include/freetype/cache/ftccache.h, include/freetype/cache/ftccmap.h, include/freetype/internal/ftcalc.h, include/freetype/internal/ftdriver.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, include/freetype/internal/psaux.h, include/freetype/internal/sfnt.h, include/freetype/internal/t1types.h, include/freetype/internal/tttypes.h, src/base/ftcalc.c, src/base/ftdbgmem.c, src/base/ftobjs.c, src/base/ftutil.c, src/bdf/bdfdrivr.c, src/cache/ftccache.c, src/cache/ftccback.h, src/cache/ftcmanag.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/psaux/psauxmod.c, src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c: Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data structures. Move newly added structure elements to the end of the affected structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is defined) to assure binary compatibility with older FreeType versions. Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old functions: ft_stub_set_char_sizes ft_stub_set_pixel_sizes Rename the following internal functions to provide the old function names as stubs: FT_Alloc -> ft_mem_alloc FT_QAlloc -> ft_mem_qalloc FT_Realloc -> ft_mem_realloc FT_QRealloc -> ft_mem_qrealloc FT_Free -> ft_mem_free FT_Alloc_Debug -> ft_mem_alloc_debug FT_QAlloc_Debug -> ft_mem_qalloc_debug FT_Realloc_Debug -> ft_mem_realloc_debug FT_QRealloc_Debug -> ft_mem_qrealloc_debug FT_Free_Debug -> ft_mem_free_debug 2006-02-15 Chia-I Wu * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove unused `max_points' and `max_contours'. * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update. * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused `max_components'. * src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused `loadSize' and `loadStack'. * src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context), src/sfnt/ttload.c (tt_face_load_maxp): Update. * src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c (sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not defined. * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions. (finally!) For most OpenType tables, `tt_face_load_xxxx' simply loads the table and `face->root' is set later in `sfnt_load_face'. Here, we try to make this work for _all_ tables. Also improve tracing messages. * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c, src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and then exit. Error handling or setting face->root is done later in `sfnt_load_face'. * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. Mac bitmap-only fonts are not scalable. Check that `face->header.Units_Per_EM' is not zero. (LOAD_, LOADM_): Emit pretty trace messages. * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from `eblc'. * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c (load_format_20, load_format_25, tt_face_get_ps_name): Use face->max_profile.numGlyphs, instead of face->root.num_glyphs. 2006-02-14 Werner Lemberg * include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in documentation that negative strength values are possible. Give an example call. * include/freetype/freetype.h (FT_GlyphSlotRec): Improve documentation of `outline' field. * src/sfnt/sfobjc.s: Inckude FT_INTERNAL_DEBUG_H. * src/sfnt/sfdriver.c: Include ttmtx.h. * src/autofit/afcjk.c: Include aftypes.h and aflatin.h. 2006-02-14 Chia-I Wu * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo. 2006-02-14 Chia-I Wu * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply return error if table is missing. Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'. * src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics tables. The last change makes Mac bitmap-only font not load and this fixes it. * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error when FT_CONFIG_OPTION_INCREMENTAL is defined. 2006-02-13 Chia-I Wu Clean up the SFNT_Interface. In this final pass, `load_hmtx' is split from `load_hhea'. * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c, src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'. * src/sfnt/sfobjs.c (sfnt_load_face): Update. 2006-02-13 Chia-I Wu * src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of code... 2006-02-13 Chia-I Wu Clean up the SFNT_Interface. In this pass, we want to treat the font directory (offset table and table directory) as a normal table like the others. This also means that TTCs are no longer recognized there but in `init_face'. * include/freetype/internal/sfnt.h (SFNT_Interface), src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are combined and renamed to `load_font_dir'. * src/sfnt/ttload.h, src/sfnt/ttload.c: s/sfnt_dir_check/check_table_dir/. `sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'. `tt_face_load_sfnt_header' and `tt_face_load_directory' are combined and renamed to `tt_face_load_font_dir'. * src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here. 2006-02-13 Chia-I Wu Clean up the SFNT_Interface. Table loading functions are now named after the tables' tags; `hdmx' is TrueType-specific and thus the code is moved to the truetype module; `get_metrics' is moved here from the truetype module so that the code can be shared with the cff module. This pass involves no real changes. That is, the code is moved verbatim mostly. The only exception is the return value of `tt_face_get_metrics'. * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files. Metrics-related tables' loading and parsing code is moved to here. Move `tt_face_get_metrics' here from the truetype module. The return value is changed from `void' to `FT_Error'. * include/freetype/internal/fttrace.h: New trace: ttmtx. * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and parsing code is moved here. New function `tt_face_load_prep' split from `tt_face_load_fpgm'. `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. * src/cff/cffgload.c, src/cff/cffobjs.c: Update. * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update. 2006-02-11 Chia-I Wu * src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug... * src/autofit/aflatin.c (af_latin_metrics_init_widths): Use AF_LatinMetricsRec as the dummy metrics because we cast the metrics to it later in `af_latin_hints_link_segments'. 2006-02-11 Chia-I Wu * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define to enable autofit CJK script support. (#define'd by default.) * src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure that `edge_distance_threshold' is always set. (af_latin_hints_link_segments): Potential divide-by-zero bug. Use latin constant in the scoring formula. * src/autofit/afcjk.c: Minor updates due to the above three changes. * docs/TODO, docs/CHANGES: Updated. 2006-02-09 Chia-I Wu Introduce experimental autofit CJK module based on akito's autohint patch. You need to #define AF_MOD_CJK in afcjk.c to enable it. * src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c, src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h: Add CJK module based on akito's autohint patch. * src/autofit/afhints.h (AF_SegmentRec): New field `len' for the overlap length of the segments. (AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros. * src/autofit/aflatin.h (af_latin_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'. Use the character given by the caller. (af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale the thresholds. * src/autofit/afloader.c (af_loader_load_g): Respect AF_SCALER_FLAG_NO_ADVANCE. 2006-02-09 Werner Lemberg * src/cid/cidparse.c (cid_parse_new): Remove shadowing variable. 2006-02-09 suzuki toshiya * src/cid/cidparse.c (cid_parse_new): Fix for abnormally short or broken CIDFont. Reported by Taek Kwan(TK) Lee (see ft-devel 2005-11-02). 2006-02-08 suzuki toshiya * builds/unix/configure.ac: Fix bug for `--with-old-mac-fonts' option on UNIX platform. It has been broken since 2006-01-11. 2006-02-01 Werner Lemberg * src/otvalid/module.mk: s/otvalid_module_class/otv_module_class/. * src/gxvalid/module.mk: s/gxvalid_module_class/gxv_module_class/. * builds/unix/unixddef.mk: Actually do define PLATFORM (fixing change from 2006-01-31). (TOP_DIR, OBJ_DIR): Update. * builds/unix/install.mk (install): Fix path for ftmodule.h. * Makefile, *.mk, builds/unix/unix-cc.in, builds/unix-def.in: Use `?=' where appropriate. * builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR), builds/win32/w32-dev.mk (TOP_DIR): Removed. Defined elsewhere. 2006-01-31 Werner Lemberg Implement new, simplified module selection. With GNU make it is now sufficient to modify a single file, `modules.cfg', to control the inclusion of modules and base extension files. This change also fixes the creation of ftmodule.h; it now depends on `modules.cfg' and thus is rebuilt only if necessary. Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the default location. * modules.cfg: New file. * builds/freetype.mk: Don't include `modules.mk'. Include all `rules.mk' files as specified in `modules.cfg'. (FTOPTION_FLAG, FTOPTION_H): New variables. (FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H. Add FTOPTION_FLAG. ($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST. (CONFIG_H): Add FTMODULE_H and FTOPTION_H. (INCLUDES): Add DEVEL_DIR. (INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ, OBJ_M, OBJ_S): Use `:=', not `='. (remove_ftmodule_h): New phony target to delete `ftmodule.h'. (distclean): Add remove_ftmodule_h. * builds/modules.mk: (MODULE_LIST): Removed. (make_module_list, clean_module_list): Replace targets with... (FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New variables. Reason for the change is that it is not possible to have a phony prerequisite which is run only if the target file must be rebuilt (phony prerequisites act like subroutines and are *always* executed). We only want to rebuild `ftmodule.h' if `module.cfg' is changed. Update all callers. ($FTMODULE_H)): Rule to create `ftmodule.h', depending on `modules.cfg'. * builds/toplevel.mk: Rewrite and simplify module handling. (MODULES_CFG, FTMODULE_H): New variables. Include MODULES_CFG. (MODULES): New variable to include all `module.mk' and `rules.mk' files. We no longer use make's `wildcard' function for this. * Makefile (USE_MODULES): Remove. Update all users. (OBJ_DIR): Define it here. * src/*/module.mk: Change make_module_list: foo foo: ... to FTMODULE_H_COMMANDS += FOO define FOO ... endef in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'. * src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS. * builds/unix/detect.mk (setup): Always execute `configure' script. (have_mk): Rename to... (have_Makefile): This. Don't use `strip' function. * builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is defined. (have_mk): Don't use `strip' function. Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test accordingly). * builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'. * builds/os2/os2-dev.mk, builds/unix/unix-dev.mk, builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. * builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR), builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in (TOP_DIR, OBJ_DIR): Removed. Defined elsewhere. * builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR), builds/win32/win32-def.mk (OBJ_DIR): Removed. Defined elsewhere. * builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. Don't define PLATFORM. * configure: Copy `modules.cfg' to builddir if builddir != srcdir. Update snippet taken from autoconf's m4sh.m4 to current CVS version. Be more verbose. * include/freetype/config/ftmodule.h: Add comments -- this file is no longer used if FreeType is built with GNU make. * docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY, docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism. Other minor updates. * modules.txt: Removed. Contents included in `modules.cfg'. * include/freetype/internal/ftmemory.h (FT_QAlloc_Debug, FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos. * src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug, FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug) [FT_STRICT_ALIASING]: Implement. 2006-01-31 Chia-I Wu * src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c (cid_face_init), src/pfr/pfrobjs.c (pfr_face_init), src/type1/t1objs.c (T1_Face_Init): Set face->height to MAX(1.2 * units_per_EM, ascender - descender). 2006-01-31 Chia-I Wu * include/freetype/internal/t1types.h (AFM_FontInfo), src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox', `Ascender', and `Descender' from an AFM. * src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM. * include/freetype/freetype.h (FT_FaceRec): Mention that fields may be changed after file attachment. 2006-01-28 Werner Lemberg * src/*/module.mk (.PHONY): Add. 2006-01-27 Werner Lemberg * README, docs/FTL.TXT: Fix email address for bug reports. Other minor formatting. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. * src/autofit/module.mk (add_autofit_module), src/bdf/module.mk (add_bdf_module), src/type42/module.mk (add_type42_driver): Fix whitespace. * src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv renderer classes. 2006-01-27 David Turner * builds/unix/configure.ac: Fix build problem on Cygwin. * builds/unix/install.mk (install): Don't install the internal headers, and remove existing ones if found in the target install directory. * src/autofit/afwarp.c: Add simple #ifdef to prevent compilation if the warp hinter isn't active (it shouldn't, still experimental). * Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid' and `otvalid' from the list of modules that are linked statically to a given FreeType library. Functionality has been moved to the `ftvalid' CVS module. Note also that current Make-based build system still compiles the modules though. * include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro which controls the definitions of the memory management functions to avoid warnings with recent versions of GCC. This macro is only here to be disabled, in case we detect problems with the new scheme. NOTE: Disable macro to use the memory debugger -- this will be fixed later! * include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc, FT_QAlloc, FT_Realloc, FT_QRealloc, FT_Free) [FT_STRICT_ALIASING]: New versions. * builds/win32/visualc/freetype.dsp: Updating project file to define FT2_BUILD_LIBRARY, and remove gxvalid + otvalid modules from compilation. * builds/freetype.mk (FT_CFLAGS), Jamfile (DEFINES): Define the macro FT2_BUILD_LIBRARY when compiling the library. * include/freetype/config/ftheader.h: Remove inclusions of internal headers except if the macro FT2_BUILD_LIBRARY is defined. * include/freetype/internal/psaux.h (AFM_KernPair, AFM_TrackKern, AFM_FontInfo): Move structure declarations to... * include/freetype/internal/t1types.h: This file. * (many files): Fix compiler warnings. Various minor reorganizations. * src/cff/cffload.c (cff_font_done): Don't free static array `subfonts'. * src/otvalid/otvcommn.c (otv_ClassDef_validate), src/otvalid/otvgpos.c (otv_x_sxy): Fix debugging information. Get rid of writable static variables (i.e., the string table) in afmparse, and fix compilation in FT2_MULTI mode. * src/psaux/afmparse.c: Include ft2build.h and FT_FREETYPE_H. (AFM_MAX_ARGUMENTS): Define... * src/psaux/afmparse.h: Here. * src/psaux/Jamfile (_sources): Add afmparse. * src/psaux/psconv.c: Include psconv.h. * src/type1/t1afm.c: Don't include FT_INTERNAL_TYPE1_TYPES_H but FT_INTERNAL_POSTSCRIPT_AUX_H. * src/type1/t1afm.h: Include FT_INTERNAL_TYPE1_TYPES_H. 2006-01-23 Chia-I Wu * include/freetype/freetype.h (FT_Select_Size): Rename the second argument from `idx' to `strike_index'. (FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of this enum. * include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH, FT_REQUEST_HEIGHT): New macros to get the width and height of a request, in fractional pixels. * include/freetype/internal/ftobjs.h (FT_Select_Metrics, FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics, FT_Request_Metrics): New base functions to set the font metrics. They were part of FT_Select_Size/FT_Request_Size and are made independent functions so that metrics are not set again and again. * src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set only when driver's size_select/size_request is NULL. That is, drivers should set the metrics themselves. (FT_Match_Size): Round before matching. This was what we did and it does cause some problems without rounding. * src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c (tt_size_select): Set the font metrics. s/index/strike_index/. The scaled metrics are always preferred over strikes' metrics, even when some strike is selected. This is done because the strikes' metrics are not reliable, e.g., the sign of the descender is wrong for some fonts. * src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c (tt_size_request): Set the font metrics. Call cff_size_select/tt_size_select when some strike is matched. * src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c, src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c, src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c: Set the font metrics. s/index/strike_index/. * src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these files were committed. Just a catch-up. (PS_Conv_ToFixed): Remove the `goto'. (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little. * src/sfnt/ttsbit.c (tt_face_load_sbit_strikes, tt_face_load_strike_metrics), src/sfnt/ttsbit0.c (tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The advertised metrics in `available_sizes' are different from those actually used. 2006-01-23 Chia-I Wu * src/psaux/psaux.c src/psaux/psauxmod.c src/type1/t1driver.c: Make AFM parser optional, controlled by `T1_CONFIG_OPTION_NO_AFM'. 2006-01-22 Werner Lemberg * builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from `texinfo' CVS module at savannah.gnu.org. 2006-01-21 Werner Lemberg * src/autofit/rules.mk (AUTOF_DRV_SRC): Add afwarp.c. * src/autofit/afloader.c (af_loader_load_g): Move AF_USE_WARPER up to avoid compiler warnings. * src/autofit/afwarp.c (af_warper_compute_line_best): Remove shadowing variable declarations. Fix warning parameters and replace printf with AF_LOG. (af_warper_compute): Remove unused variable. 2006-01-20 David Turner Adding experimental implementation of `warp hinting' (new hinting algorithm for gray-level and LCD rendering). It is disabled by default, you need to #define AF_USE_WARPER in aftypes.h. * src/autofit/afhints.c (af_glyph_hints_scale_dim) [AF_USE_WARPER]: New function. * src/autofit/afhints.h: Updated. * src/autofit/aflatin.c [AF_USE_WARPER]: Include afwarp.h. (af_latin_hints_init) [AF_USE_WARPER]: Reset mode to FT_RENDER_MODE_NORMAL if an LCD mode is selected.

The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real change need be made to the code. * src/base/ftobjs.c (FT_Load_Glyph): Resolve flag dependencies and decide whether to use the auto-hinter according to documentation. There should to be no real difference. Some checks (e.g., is text height positve?) after the glyph is loaded. (FT_Select_Size, FT_Request_Size): Scales are set to wrong values.

The number of available faces are passed via face->num_faces. If bitmap faces are embedded in sfnt resource, face->num_fixed_size is correctly set. In public API, FT_New_Face() and FT_New_Face_From_FSSpec() count the faces as FT_GetFile_From_Mac_Name(), which ignores NFNT resources. * doc/CHANGES: Mention the changes. 2005-12-17 Chia-I Wu * src/truetype/ttinterp.c (Update_Max): Set current size of buffer correctly (so that memory debug system won't panic). 2005-12-16 Chia-I Wu * include/freetype/internal/ftobjs.h (ft_glyphslot_grid_fit_metrics), src/base/ftobjs.c (ft_glyphslot_grid_fit_metrics): Removed. * src/base/ftobjs.c (ft_recompute_scaled_metrics): Do not round. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/truetype/ttgload.c (compute_glyph_metrics), src/type1/t1gload.c (T1_Load_Glyph): Do not round glyph metrics. * doc/CHANGES: Mention the changes. 2005-12-13 David Turner Change the implementation of the LIGHT hinting mode to completely disable horizontal hinting. This is an experimental effort to integrate David Chester's latest patch without affecting the other hinting modes as well. Note that this doesn't force auto-hinting for all fonts, however. * src/autofit/afhints.c (af_glyph_hints_reload): Don't set scaler_fiags here but... (af_glyph_hints_rescale): Here. * src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal hinting for `light' hinting mode. * Jamfile: Small fix to ensure that ftexport.sym is placed into the same location as other generated objects (i.e., within the `objs' directory of the current directory). Add support for an embedded `BDF ' table within SFNT-based bitmap font files. This is used to store atoms & properties from the original BDF fonts that were used to generate the font file. The feature is controlled by TT_CONFIG_OPTION_BDF within `ftoption.h' and is used to implement FT_Get_BDF_Property for these font files. At the moment, this is still experimental, the BDF table format isn't cast into stone yet. * include/freetype/config/ftoption.h (TT_CONFIG_OPTION_BDF): New macro. * include/freetype/config/ftstdlib.h (ft_memchr): New macro. * include/freetype/internal/tttypes.h (TT_BDFRec, TT_BDF) [TT_CONFIG_OPTION_BDF]: New structure.

(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros. * src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined. (TT_CMap4Rec_): Remove `old_charcode' and `table_length'. (tt_cmap4_reset): Removed. (tt_cmap4_init): Updated accordingly. (tt_cmap4_next): Updated accordingly. Take care of overlapping segments. (tt_cmap4_validate): Make sure the subtable is large enough. Do not check glyph_ids because some fonts set the length wrongly. Also, if all segments have offset 0, glyph_ids is always invalid. It does not cause any problem so far only because the check misses equality. Distinguish between unsorted and overlapping segments. (tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions to do `charcode => glyph index' by linear/binary search. (tt_cmap4_char_index, tt_cmap4_char_next): Use tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.
