This fixes repeated calls of the script. Reported by Nelson Beebe and Behdad Esfahbod. * README.CVS: Mention file permissions. 2005-05-23 Werner Lemberg <wl@gnu.org> * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk (CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove -fno-strict-aliasing. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c -- it is currently loaded from ttsbit.c. 2005-05-23 Behdad Esfahbod <behdad@cs.toronto.edu> Say you have `(Foo*)x' and want to assign, pass, or return it as `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler would warn you that type casting incompatible pointer types breaks strict-aliasing. The solution is to cast to `(void*)' instead which is the generic pointer type, so the compiler knows that it should make no strict-aliasing assumption on `x'. But the problem with `(void*)x' is that seems like in C++, unlike C, `void*' is not a generic pointer type and assigning `void*' to `Bar*' without a cast causes an error. The solution is to cast to `Bar*' too, with `(Bar*)(void*)x' as the result -- this is what the patch does. * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP), include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove cast on lvalue, use a temporary pointer instead.

The idea is to avoid loading and decoding tables in the heap, and instead access the raw data whenever possible (i.e., when it doesn't compromise performance). This has several benefits: For example, opening vera.ttf now uses just a small amount of memory (even when the FT_Library footprint is accounted for), until you start loading glyphs. Even then, you save at least 20KB compared to the non-optimized case. Performance of various operations, including open and close, has also been dramatically improved. More optimizations to come, especially for the auto-hinter. * include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New function type.

Update all callers. * src/truetype/ttgload.h: Updated. 2005-02-22 David Turner <david@freetype.org> * src/base/ftdbgmem.c: Partly rewritten. Added the ability to list all allocation sites in the memory debugger. Also a new function FT_DumpMemory() was added. It is only available in builds with FT_DEBUG_MEMORY defined, and you must declare it in your own code to use it, i.e., with something like: extern void FT_DumpMemory( FT_Memory ); ...

Fix error message. 2004-06-23 David Turner <david@freetype.org> * include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug, FT_QRealloc_Debug): New functions that perform allocation without zero-ing out the corresponding blocks. * include/freetype/internal/ftmemory.h (FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY, FT_MEM_QRENEW_ARRAY, FT_QALLOC, FT_QREALLOC, FT_QNEW, FT_QNEW_ARRAY, FT_QRENEW_ARRAY): New macros. * src/base/ftstream.c (FT_Stream_EnterFrame): Use FT_QALLOC. * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use FT_QNEW_ARRAY. * src/sfnt/sfobjs.c (tt_face_get_name): Use FT_QNEW_ARRAY. * src/sfnt/ttload.c (tt_face_load_directory, tt_face_load_metrics, tt_face_load_gasp): Use FT_QNEW_ARRAY. (tt_face_load_kern): Use FT_QNEW_ARRAY. Small optimization in the kerning table verifier; this speeds up TrueType face opening by about 7%. (tt_face_load_hdmx): Use FT_QNEW_ARRAY and FT_QALLOC. * include/freetype/config/ftmodule.h: Changed the order of modules, putting TrueType and Type 1 first. This dramatically improves the performance of face open/close operations. For example, putting the TrueType driver first in the list results in a 5x speedup when opening `Vera.ttf'. The very problem is that both the PCF and BDF drivers do a lot more than necessary to detect that they cannot handle a font file. 2004-06-22 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_read_TOC, pcf_get_properties, pcf_get_metrics, pcf_get_bitmaps, pcf_get_encodings): Improve debugging messages. * src/pcf/pcfdrivr.c (FT_COMPONENT): Move up. (PCF_Face_Init): Simplify code. * src/bdf/bdfdrivr.h (BDF_FaceRec): New element `default_glyph'. * src/bdf/bdflib.c (_bdf_add_property, _bdf_parse_start), src/bdf/bdf.h (bdf_font_t): s/default_glyph/default_char/. * src/bdf/bdfdrivr.c (BDF_Face_Init): Fix number of glyphs. Set `default_glyph'. (BDF_Glyph_Load): Use `default_glyph' for undefined glyph. * docs/CHANGES: Updated. 2004-06-21 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2004-06-21 David Turner <david@freetype.org> * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Don't access (unrounded) `TT_Size.root.metrics' but (rounded) `TT_Size.metrics'. This fixes a scaling bug that caused incorrect rendering when the bytecode interpreter was enabled. 2004-06-14 Huw D M Davies <h.davies1@physics.ox.ac.uk> * src/winfonts/winfnt.c (FNT_Face_Init): Set x_ppem and y_ppem based on pixel_width and pixel_height. (FNT_Size_Set_Pixels): Updated. 2004-06-14 Werner Lemberg <wl@gnu.org> * src/lzw/zopen.c: Comment out inclusion of signal.h and unistd.h. Reported by Hyvärinen Jyrki Juhani. 2004-06-11 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2004-06-10 David Turner <david@freetype.org> * src/base/ftobject.c, src/base/fthash.c, src/base/ftexcept.c, src/base/ftsysio.c, src/base/ftsysmem.c, src/base/ftlist.c: Removed. Obsolete. * src/raster/ftraster.c (Alignment, PAlignment): New union to fix problems with 64bit systems. (AlignProfileSize): Use it. 2004-06-08 David Turner <david@freetype.org> * include/freetype/freetype.h (FT_Glyph_Metrics): Move `lsb_delta' and `rsb_delta' elements to...

Update all users. * src/sfnt/sfobjs.c (tt_face_get_name): Remove compiler warning. * src/winfonts/winfnt.c (FNT_Load_Glyph): Add missing initialization of slot->metrics.width and slot->metrics.height when loading a Windows FNT glyph. Thanks to Huw Davies. * include/freetype/cache/ftcmru.h (FTC_MruNode_CompareFunc): Change return type to FT_Bool. * src/cache/ftcbasic.c (ftc_basic_family_compare): Change return type to FT_Bool. * src/cache/ftccache.c (FTC_Cache_Init, ftc_cache_init): Make the former call the latter, not vice versa. (FTC_Cache_Done, ftc_cache_done): Ditto. * src/cache/ftcglyph.c (FTC_GNode_Compare, ftc_gnode_compare): Make the former call the latter, not vice versa. (FTC_GCache_Init, ftc_gcache_init): Ditto.

The output now seems to be 100% equivalent to the auto-hinter, while being about 2% faster (which proves that script-specific algorithm selection isn't a performance problem). To test it, change `autohint' to `autofit' in <freetype/config/ftmodule.h> and recompile. A few more testing is needed before making this the official auto-hinting module. 2004-06-02 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (compute_glyph_metrics): Fix compiler warnings. 2004-06-01 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (tt_face_get_name): Make sure that an English name record for the Apple platform is preferred to a non-English entry for the Microsoft platform.

At least one font (app850.fon from WinME) contains different FNT charmaps for its subfonts. Consequently, the previous design of having multiple bitmap strikes in a single font face fails since we have only one charmap per face. * include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed. (FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with `font'. * src/base/ftwinfnt.c (FT_Get_WinFNT_Header): Updated. * src/winfonts/winfnt.c (fnt_font_load): Don't set pixel_width equal to pixel_height.

(FNT_Size_Set_Pixels): To find a strike, first check pixel_height only, then try to find a better hit by comparing pixel_width also. Without this fix it isn't possible to access all strikes. Also compute metrics.max_advance to be in sync with other bitmap drivers. * src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code. (FT_Set_Pixel_Sizes): Assign value to `metrics' after validation of arguments. 2003-06-20 Werner Lemberg <wl@gnu.org> Synchronize computation of height and width for bitmap strikes. The `width' field in the FT_Bitmap_Size structure is now only useful to enumerate different strikes. The `max_advance' field of the FT_Size_Metrics structure should be used to get the (maximum) width of a strike. * src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single argument to function. * src/psnames/psmodule.c (ps_unicode_value): Handle `.' after `uniXXXX' and `uXXXX[X[X]]'. 2003-06-19 Werner Lemberg <wl@gnu.org> * src/bdf/bdfdrivr.c: s/FT_Err_/BDF_Err/. * src/cache/ftccache.c, src/cache/ftcsbits.c, src/cache/ftlru.c: s/FT_Err_/FTC_Err_/. * src/cff/cffcmap.c: s/FT_Err_/CFF_Err_/. * src/pcf/pcfdrivr.c: s/FT_Err_/PCF_Err_/. * src/psaux/t1cmap.c: Include psauxerr.h. s/FT_Err_/PSaux_Err_/. * src/pshinter/pshnterr.h: New file. * src/pshinter/rules.mk: Updated. * src/pshinter/pshalgo.c, src/pshinter/pshrec.c: Include pshnterr.h. s/FT_Err_/PSH_Err_/. * src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfrsbit.c: s/FT_Err_/PFR_Err_/. * src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c: s/FT_Err_/SFNT_Err_/. * src/truetype/ttgload.c: s/FT_Err_/TT_Err_/. * src/gzip/ftgzip.c: Load FT_MODULE_ERRORS_H and define FT_ERR_PREFIX and FT_ERR_BASE. s/FT_Err_/Gzip_Err_/. 2003-06-19 Dirck Blaskey <listtarget@danbala.com> * src/cff/cffload (cff_encoding_load): `nleft' must be FT_UInt, otherwise adding 1 might wrap the result. 2003-06-18 Werner Lemberg <wl@gnu.org> * src/psnames/psmodule.c (ps_unicode_value): Add support to recognize `uXXXX[X[X]]' glyph names.

(PFR_DRV_H): Add pfrtypes.h. * include/freetype/config/ftconfig.h: s/__MWKS__/__MWERKS__/. 2003-06-08 Karl Schultz <kschultz@rsinc.com> * src/pfr/pfrsbit.c (pfr_bitwriter_init): Change type of third argument to FT_Bool. (pfr_lookup_bitmap_data): Change type of third and fourth argument to FT_UInt. Updated caller. (pfr_load_bitmap_bits): Change type of fourth argument to FT_Bool. 2003-06-08 Werner Lemberg <wl@gnu.org> Completely revised FreeType's make management. . In all makefiles `/' is used as the path separator. The conversion to the real path separators is done as late as possible using $(subst ...). . $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator for the operating system, and the new $(COMPILER_SEP) the path separator for the compiler tools. . $(BUILD) has been renamed to $(BUILD_DIR). In general, all directory variables end with `_DIR'. The variants ending in `_' (like `BASE_' have been removed). The following ChangeLog entries only describe changes which are not related to the redesign. * builds/beos/beos-def.mk (BUILD_DIR): Fix typo. * builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid overlong arguments as suggested by J.

There exist fonts (containing e.g. form drawing characters) which intentionally have a zero line gap value. * src/truetype/ttinterp.c (Free_Project, CUR_Func_freeProj): Removed. Unused. Updated all callers. 2003-06-02 Werner Lemberg <wl@gnu.org> * src/cff/cffobjs.c (cff_face_init): Use symbolic names for Adobe specific encoding IDs (there was a wrong EID value for custom encoding). * src/cff/cffcmap.h (CFF_CMapStdRec): Remove `count'. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_encoding_done): Updated.

Updated all callers. * src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height similar to the PCF driver. * src/bdf/bdf.h (_hashnode): Use `const' for `key'. Updated. * src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask' is declared twice. It is perhaps better to modify the zlib source files directly instead of this hack. (zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts to make build with g++ successful. 2003-04-24 Manish Singh <yosh@gimp.org> * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Split on `-' also for searching the style name. 2003-04-24 David Turner <david@freetype.org> * src/pcf/pcfread.c (pcf_load_font): Fixed the computation of face->num_glyphs.

Without this change, many CJK fonts from Dynalab are rejected. 2003-04-23 Joe Marcus Clarke <marcus@FreeBSD.org> * src/base/ftbdf.c (FT_Get_BDF_Property): Check for valid `get_interface'. 2003-04-23 Paul Miller <paulm@profoundeffects.com> * src/base/ftmac.c (parse_fond): Fix handling of style names. 2003-04-23 Werner Lemberg <wl@gnu.org> * src/pfr/pfrload.c (pfr_extra_item_load_font_id): Use FT_PtrDist instead of FT_UInt for `len'. 2003-04-22 Werner Lemberg <wl@gnu.org> * src/gzip/ftgzip.c (zcalloc) [!FT_CONFIG_OPTION_SYSTEM_ZLIB]: Convert K&R format to modern C usage. (FT_Stream_OpenGzip): Use long constant. 2003-04-21 Werner Lemberg <wl@gnu.org> * src/cache/ftccache.c (ftc_cache_lookup): Remove shadow declaration of `manager'. 2003-04-20 Werner Lemberg <wl@gnu.org> * doc/INSTALL.UNX: Cleaned up. 2003-04-09 Torrey Lyons <torrey@mrcla.com> * src/base/ftmac.c (open_face_from_buffer): Removed a double-free bug that had nasty consequences when trying to open an `invalid' font on a Mac. 2003-04-09 Mike Fabian <mfabian@suse.de> * src/bdf/bdfdrivr.h (BDF_encoding_el), src/pcf/pcf.h (PCF_EncodingRec): Changed FT_Short to FT_UShort in order to be able to access more than 32768 glyphs in fonts. 2003-04-08 David Turner <david@freetype.org> * Version 2.1.4 released. ========================= 2003-04-03 Martin Muskens <mmuskens@aurelon.com> * src/type1/t1load.c (T1_Open_Face): Fixed the code to make it handle special cases where a font only contains a `.notdef' glyph (happens in PDF-embedded fonts). Otherwise, FT_Panic was called. 2003-03-27 David Turner <david@freetype.org> * README: Updated. * README.UNX: Removed (now replaced by docs/INSTALL.UNX). * src/pshinter/pshalgo3.c: The hinter now performs as in 2.1.3 and will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is used. (psh3_dimension_quantize_len): Enabled. (psh3_hint_align): Enable commented code. (psh3_hint_align_light): Commented out. * src/base/ftobjs.c (FT_Set_Char_Size): Changed the default computations to include rounding in all cases; this is required to provide accurate kerning data when native TrueType hinting is enabled. * src/type1/t1load.c (is_name_char): The Type 1 loader now accepts more general names according to the PostScript specification (the previous one was too restrictive). (parse_font_name, parse_encoding, parse_charstrings, parse_dict): Use `is_name_char'. (parse_subrs): Handle empty arrays. 2003-03-20 David Turner <david@freetype.org> Serious rewriting of the documentation. * docs/BUGS, docs/BUILD: Removed. * docs/DEBUG.TXT: Renamed to... * docs/DEBUG: This. * docs/CUSTOMIZE, docs/TRUETYPE, docs/UPGRADE.UNX: New files. * docs/INSTALL.ANY, docs/INSTALL.UNX, docs/INSTALL.GNU New files, containing platform specific information previously in INSTALL. * docs/readme.vms: Renamed to... * docs/INSTALL.VMS: This. * docs/*: Updated. Introduced three new functions to deal with glyph bitmaps within FT_GlyphSlot objects: ft_glyphslot_free_bitmap ft_glyphslot_alloc_bitmap ft_glyphslot_set_bitmap These functions are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP flag manually. * include/freetype/internal/ftobjs.h (ft_glyphslot_free_bitmap, ft_glyphslot_alloc_bitmap, ft_glyphslot_set_bitmap): New functions. * src/base/ftobjs.c: Implement them. (ft_glyphslot_done): Use ft_glyphslot_free_bitmap. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdriver.c (PCF_Glyph_Load): Remove unused variable `memory'. Use `ft_glyphslot_*' functions. Don't set `FT_GLYPH_OWN_BITMAP'. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Use `ft_glyphslot_alloc_bitmap'. * src/sfnt/ttsbit.c (Load_SBit_Image): Change 5th argument to type `FT_GlyphSlot'. Adding argument `depth' to handle recursive calls. Use `ft_glyphslot_alloc_bitmap'. (tt_face_load_sbit_image): Remove unused variable `memory'. Don't handle `FT_GLYPH_OWN_BITMAP'. Update call to Load_SBit_Image. * src/type42/t42objs.c (ft_glyphslot_clear): Renamed to... (t42_glyphslot_clear): This. Updated caller. Call `ft_glyphslot_free_bitmap'. * src/winfonts/winfnt.c (FNT_Load_Glyph): Use `ft_glyphslot_set_bitmap'. Don't handle `FT_GLYPH_OWN_BITMAP'. * src/cache/ftlru.c (FT_LruList_Lookup): Fixed an invalid assertion check. * src/autohint/ahglyph.c (ah_outline_load): Add two scaling arguments. * src/autohint/ahglyph.h: Updated. * src/autohint/ahhint.c (ah_hinter_load): Updated. * src/autohint/ahglobal.c (ah_hinter_compute_widths): Updated. * src/cache/ftccache.c (ftc_family_done): Fixed small bug that could crash the cache in rare circumstances (mostly with broken fonts). 2003-03-15 David Turner <david@freetype.org> * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding bug. Actually, it seems that previous versions of FreeType didn't perform TrueType rounding exactly as appropriate. 2003-03-14 David Turner <david@freetype.org> * src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small TrueType native rendering glitches; they came from a small rounding error. 2003-03-13 David Turner <david@freetype.org> Added new environment variables to control memory debugging with FreeType. See the description of `FT2_DEBUG_MEMORY', `FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT. * src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count', `bound_total', `alloc_total_max', `bound_count', `alloc_count_max'. (ft_mem_debug_alloc): Handle new variables. (ft_mem_debug_init): s/FT_DEBUG_MEMORY/FT2_DEBUG_MEMORY/. Handle new environment variables. * docs/DEBUG.TXT: Updated. Fixed the cache sub-system to correctly deal with out-of-memory conditions. * src/cache/ftccache.c (ftc_node_destroy): Comment out generic check. (ftc_cache_lookup): Implement loop. * src/cache/ftccmap.c: Define FT_COMPONENT. * src/cache/ftcsbits.c (ftc_sbit_node_load): Handle FT_Err_Out_Of_Memory. * src/cache/ftlru.c: Include FT_INTERNAL_DEBUG_H. (FT_LruList_Lookup): Implement loop. * src/pfr/pfrobjs.c (pfr_face_done): Fix memory leak. (pfr_face_init): Fixing compiler warnings. * src/psaux/psobjs.c (reallocate_t1_table): Fixed a bug (memory leak) that only happened when a try to resize an array would end in an out-of-memory condition. * src/smooth/ftgrays.c (gray_convert_glyph): Removed compiler warnings / volatile bug. * src/truetype/ttobjs.c (tt_glyphzone_done): Removed segmentation fault that happened in tight memory environments. 2003-02-28 Pixel <pixel@mandrakesoft.com> * src/gzip/ftgzip.c (ft_gzip_file_done): Fixed memory leak: The ZLib stream was not properly finalized. 2003-02-25 Anthony Fok <anthony@thizlinux.com> * src/cache/ftccmap.c: Include FT_TRUETYPE_IDS_H. (ftc_cmap_family_init): The cmap cache now supports UCS-4 charmaps when available in Asian fonts. * src/sfnt/ttload.c, src/base/ftobjs.c: Changed `asian' to `Asian' in comments. 2003-02-25 David Turner <david@freetype.org> * src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that caused FreeType to loop endlessly when trying to read certain compressed gzip files. The following test reveals the bug: touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz Several fixes to the PFR font driver: - The list of available embedded bitmaps was not correctly set in the root FT_FaceRec structure describing the face. - The glyph loader always tried to load the outlines when FT_LOAD_SBITS_ONLY was specified. - The table loaded now scans for *undocumented* elements of a physical font's auxiliary data record. This is necessary to retrieve the `real' family and style names. NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS! * src/pfr/pfrload.c (pfr_aux_name_load): New function. (pfr_phy_font_done): Free `family_name' and `style_name' also. Remove unused variables. (pfr_phy_font_load): Extract useful information from the auxiliary bytes. * src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL. (pfr_face_init): Provide fallback values for `family_name' and `style_name'. Handle strikes. (pfr_slot_load): Handle FT_LOAD_SBITS_ONLY. * src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent', `descent', `leading', `family_name', and `style_name'. * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug when computing the scale factors for a given character size in points with resolution. * devel/ft2build.h, devel/ftoption.h: New files (in a new directory) which are special development versions of include/ft2build.h and include/freetype/config/ftoption.h, respectively. 2003-02-18 David Turner <david@freetype.org> Fixing the slight distortion problem that occurred due to the latest auto-hinter changes. * src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding. * src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'. [!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed. * src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'. * src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of `metrics'. [FT_CONFIG_CHESTER_ASCENDER]: Code removed. (Reset_SBit_Size): Fix initialization of `metrics'. * src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of `exec->metrics'. * src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width `correction' which seemed to provide more trouble than benefits. 2003-02-13 Graham Asher <graham.asher@btinternet.com> Changed the incremental loading interface in a way that makes it simpler and allows glyph metrics to be changed (e.g., by adding a constant, as required by CFF fonts) rather than just overridden. This was required to make the GhostScript-to-FreeType bridge work. * src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]: Allow metrics to be overridden. * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Ditto. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Simplify. (compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block moved down. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * include/freetype/ftincrem.h: Updated. 2003-01-31 David Turner <david@freetype.org> * docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation for the 2.1.4 release. * builds/win32/visualc/freetype.dsp, builds/win32/visualc/index.html: Updating the project file for 2.1.4. * src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c, src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c, src/gzip/infutil.c: Removed old-style (K&R)function definitions. This avoids warnings with Visual C++ at its most pedantic mode. * src/pfr/pfrsbit.c: Removed compiler warnings. * src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR into an FT_TRACE1 since it caused `ftview' and others to dump too much junk when trying to display a waterfall with a font without a Unicode charmap (e.g. SYMBOL.TTF). Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last patch from David Chester, but with a much simpler (and saner) implementation. * src/autohint/ahhint.c (ah_hinter_load_glyph) [FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that the top of non-capital letters is aligned on a pixel boundary whenever possible. * src/base/ftobjs.c (FT_Set_Char_Size) [FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently. * src/truetype/ttdriver.c (Set_Char_Sizes) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only if this macro is defined. * src/truetype/ttobjs.c (Reset_Outline_Size) [FT_CONFIG_CHESTER_ASCENDER]: Round differently. * src/pshinter/pshalgo3.c: Improved the Postscript hinter. Getting rid of stem snapping seems to work well here (though the stems are still slightly moved to increase contrast). (psh3_dimension_quantize_len): Commented out. (psh3_hint_align_light): New function. (psh3_hint_align): Comment out some code. THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES STILL SUCK. 2003-01-22 David Chester <davidchester@qmx.net> * src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the stem width optimization. 2003-01-22 David Turner <david@freetype.org> Adding a new API `FT_Get_BDF_Property' to retrieve the BDF properties of a given PCF or BDF font. * include/freetype/ftbdf.h (BDF_PropertyType): New enumeration. (BDF_Property, BDF_PropertyRec): New structure. FT_Get_BDF_Property): New function. * include/freetype/internal/bdftypes.h: Include FT_BDF_H.

(bdf_driver_class): Use `bdf_driver_requester'. * src/pcf/pcfdrivr.c: Include FT_BDF_H. (pcf_get_bdf_property, pcf_driver_requester): New functions (pcf_driver_class): Use `pcf_driver_requester'. * src/pcf/pcfread.c: Include `pcfread.h'. (pcf_find_property): Decorate it with FT_LOCAL_DEF. * src/pcf/pcfread.h: New file, providing `pcf_find_property'. * src/sfnt/ttload.c (sfnt_dir_check): Relaxed the `head' table size verification to accept a few broken fonts who pad the size incorrectly (the table should be padded, but its `size' field shouldn't according to the specification). 2003-01-18 Werner Lemberg <wl@gnu.org> * builds/unix/ltmain.sh: Regenerated with `libtoolize --force --copy' from libtool 1.4.3. * builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from automake 1.7.1. * builds/unix/configure: Regenerated with autoconf 2.54. * builds/unix/config.guess, builds/unix/config.sub: Updated from `config' CVS module at subversions.gnu.org. * builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from `automake' CVS module at subversions.gnu.org. 2003-01-15 David Turner <david@freetype.org> * include/freetype/freetype.h: Fixed documentation for FT_Size_Metrics. 2003-01-15 James Su <suzhe@turbolinux.com.cn> * src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read certain gzip-ed font files (typo: `&&' -> `&'). 2003-01-15 Huw D M Davies <h.davies1@physics.ox.ac.uk> Added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty bug in the header loader which would cause invalid memory overwrites. * include/freetype/config/ftheader.h (FT_WINFONTS_H): New macro for ftwinfnt.h. * include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H. (FNT_FontRec): Updated. Move Windows FNT definition to... * include/freetype/ftwinfnt.h: This new file. (FT_WinFNT_HeaderRec): Rename `reserved2' to `reserved1'. * src/base/ftwinfnt.c: New file, providing `FT_Get_WinFNT_Header'. * src/winfonts/winfnt.c (winfnt_header_fields): Updated. Rename `reserved2' to `reserved1'. (fnt_font_load): Updated. * src/base/Jamfile, src/base/descrip.mms, src/base/rules.mk: Updated. 2003-01-14 Graham Asher <graham.asher@btinternet.com> * include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to the type of the first argument to FT_Matrix_Multiply, which isn't changed -- this adds documentation and convenience. 2003-01-13 Graham Asher <graham.asher@btinternet.com> * src/sfnt/ttload.c (tt_face_load_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without horizontal metrics (without the `hmtx' table) are now tolerated if an incremental interface has been specified that has a get_glyph_metrics function, implying that metrics will be supplied from outside. This happens for certain Type 42 fonts passed from GhostScript. 2003-01-11 David Chester <davidchester@qmx.net> Patches to the auto-hinter in order to slightly improve the output. Note that everything is controlled through the new FT_CONFIG_OPTION_CHESTER_HINTS defined in `ftoption.h'. There are also individual FT_CONFIG_CHESTER_XXX macros to control individual `features'. Note that all improvements are enabled by default, but can be tweaked for optimization and testing purposes. The configuration macros will most likely disappear in the short future. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_CHESTER_HINTS): New macro. (FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE}) [FT_CONFIG_OPTION_CHESTER_HINTS]: New macros to control individual features. * src/autohint/ahglobal.c (blue_chars) [FT_CONFIG_CHESTER_SMALL_F]: Add blue zone for `fijkdbh'. * src/autohint/ahglobal.h (AH_IS_TOP_BLUE) [FT_CONFIG_CHESTER_SMALL_F]: Use `AH_BLUE_SMALL_F_TOP'. * src/autohint/ahglyph.c (ah_outline_compute_edges) [FT_CONFIG_CHESTER_SERIF]: Use `AH_EDGE_SERIF'. (ah_outline_compute_blue_edges) [FT_CONFIG_CHESTER_SMALL_F]: Increase threshold for `best_dist'. * src/autohint/ahhint.c (ah_compute_stem_width) [FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif handling. (ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special version of `ah_compute_stem_width'. (ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem alignment when stem widths are less than 1.5 pixels wide centers the stem slightly off-center of the center of a pixel (this increases sharpness and consistency). [FT_CONFIG_CHESTER_SERIF]: Use special version of `ah_compute_stem_width'. * src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add `AH_BLUE_SMALL_F_TOP'. 2003-01-11 David Turner <david@freetype.org> * include/freetype/internal/fnttypes.h (WinFNT_HeaderRec): Increase size of `reserved2' to avoid memory overwrites. 2003-01-08 Huw Davies <huw@codeweavers.com> * src/winfonts/winfnt.c (winfnt_header_fields): Read 16 bytes into `reserved2', not `reserved'. * src/base/ftobjs.c (find_unicode_charmap): Fixed the error code returned when the font doesn't contain a Unicode charmap. This allows FT2 to load `symbol.ttf' and a few others correctly since the last release. (open_face): Fix return value. 2003-01-08 Owen Taylor <owen@redhat.com> Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and postscript hinters. * src/autohint/ahtypes.h (AH_HinterRec): Add `do_stem_adjust'. * src/autohint/ahhint.c (ah_compute_stem_width): Handle hinter->do_stem_adjust.

(ps3_hints_apply): Handle FT_RENDER_MODE_LIGHT. * include/freetype/freetype.h (FT_Render_Mode): Add FT_RENDER_MODE_LIGHT. * src/truetype/ttgload.c: Fixing the TrueType loader to handle invalid composites correctly by limiting the recursion depth. (TT_MAX_COMPOSITE_RECURSE): New macro. (load_truetype_glyph): Add argument `recurse_count'. Load a composite only if the numbers of contours is -1, emit error otherwise. (TT_Load_Glyph): Updated. 2003-01-08 David Turner <david@freetype.org> * Jamrules, Jamfile, Jamfile.in, src/*/Jamfile: Small changes to support the compilation of FreeType 2 as part of larger projects with their own configuration options (only with Jam). 2003-01-07 David Turner <david@freetype.org> * src/base/ftstroker.c: Probably the last bug-fixes to the stroker; the API is likely to change, however. (ft_stroke_border_close): Don't record empty paths. (ft_stroke_border_get_counts): Increase `num_points' also in for loop. (ft_stroke_border_export): Don't increase `write' twice in for loops. (ft_stroker_outside): Handle `phi' together with `theta'. (FT_Stroker_ParseOutline): New function. * src/base/fttrigon.c (FT_Angle_Diff): Fixing function: It returned invalid values for large negative angle differences (resulting in incorrect stroker computations, among other things). * src/cache/ftccache.c (ftc_node_hash_unlink): Removing incorrect assertion, and changing code to avoid hash table size contraction. * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Adding `ftstroker' to default build, as optional component. 2002-12-26 David Turner <david@freetype.org> * src/gzip/adler32.c, src/gzip/infblock.c, src/gzip/inflate.c, src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h, src/gzip/zutil.h: Updates to allow compilation without compiler warnings with LCC-Win32. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 4. * builds/unix/configure.ac (version_info): Increased to 9:3:3. * builds/unix/configure: Regenerated. * docs/VERSION.DLL: Updated. 2002-12-23 Anthony Fok <anthony@thizlinux.com> * builds/unix/configure.ac, builds/unix/unix-cc.in (LINK_LIBRARY), builds/unix/unix-def.in (SYSTEM_ZLIB): Small fix to configure sub-system on Unix to allow other programs to correctly link with zlib when needed. 2002-12-19 David Turner <david@freetype.org> * include/freetype/internal/sfnt.h (SFNT_Load_Table_Func): New function pointer. * include/freetype/tttables.h (FT_Load_Sfnt_Table): New function. * src/base/ftobjs.c: Implement it. * src/sfnt/sfdriver.c (sfnt_get_interface): Handle `load_sfnt' module request. 2002-12-17 David Turner <david@freetype.org> * src/base/ftobjs.c (find_unicode_charmap): Added some comments to better explain what's happening there. (open_face): Included Graham Asher's fix to prevent faces without Unicode charmaps from loading. * src/winfonts/winfnt.c: Included George Williams's fix to support version 2 fonts correctly. (winfnt_header_fields): Updated. (fnt_font_load): Handle version 2 fonts. (FNT_Load_Glyph): Updated. 2002-12-16 David Turner <david@freetype.org> * docs/VERSION.DLL: Updating document to better explain the differences between the three version numbers being used on Unix, as well as providing an autoconf fragment provided by Lars Clausen. * src/smooth/ftgrays.c (gray_render_conic): Fixed small bug that prevented Bézier arcs with negative vertical coordinates to be rendered appropriately. 2002-12-02 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * src/base/ftobjs.c: Modified the logic to get Unicode charmaps. Now it loads UCS-4 charmaps when there is one. (find_unicode_charmap): New function. (open_face): Refer to the above one. (FT_Select_Charmap): Idem. 2002-11-29 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * include/freetype/ftgzip.h: Correct the name of the controlling macro (was __FTXF86_H__ ...). 2002-11-27 Vincent Caron <v.caron@zerodeux.net> * builds/unix/unix-def.in, builds/unix/freetype-config.in, builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Adding support for system zlib installations if available on the target platform (Unix only). 2002-11-23 David Turner <david@freetype.org> * src/cff/cffload.c (cff_charset_load, cff_encoding_load): Modified charset loader to accept pre-defined charsets, even when the font contains fewer glyphs. Also enforced more checks to ensure that we never overflow the character codes array in the encoding. 2002-11-22 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * include/freetype/ttnameid.h: Updated to latest OpenType specification. 2002-11-18 David Turner <david@freetype.org> * Version 2.1.3 released. ========================= 2002-11-07 David Turner <david@freetype.org> * src/cache/ftcsbits.c (ftc_sbit_node_load): Fixed a small bug that caused problems with embedded bitmaps. * src/otlayout/otlayout.h, src/otlayout/otlconf.h, src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otlparse.c, src/otlayout/otlparse.h, src/otlayout/otlutils.h: Updating the OpenType Layout code, adding support for the first GSUB lookups. Nothing that really compiles for now though. * src/autohint/ahhint.c (ah_align_serif_edge): Disabled serif stem width quantization. It produces slightly better shapes though this is not distinguishable with many fonts. Remove other dead code. * src/Jamfile, src/*/Jamfile: Simplified. Use $(FT2_SRC_DIR). 2002-11-06 David Turner <david@freetype.org> * include/freetype/freetype.h (FT_LOAD_TARGET_LIGHT): New macro. (FT_LOAD_TARGET, FT_LOAD_TARGET_MODE): Use `& 15' instead of `& 7'. 2002-11-05 David Turner <david@freetype.org> * include/freetype/config/ftoption.h, src/gzip/ftgzip.c: Added support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify the use of system-wide zlib. Note that this macro, as well as TT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore. This allows the build system to define them depending on the configuration (typically by adding -D flags at compile time). * src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler warnings in optimized mode relative to the `volatile' local variables. This was not a compiler bug after all, but the fact that a pointer to a volatile variable is not the same as a volatile pointer to a variable :-) The fix was to change `volatile FT_Byte* p' into `FT_Byte* volatile p'. * src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c (pfr_get_metrics), src/gzip/inftrees.c: Removed compiler warnings in optimized modes. * src/gzip/*.[hc]: Modified our zlib copy in order to prevent exporting any zlib function names outside of the component. This prevents linking problems on some platforms, when applications want to link FreeType _and_ zlib together. 2002-11-05 Juliusz <jch@pps.jussieu.fr> * src/psaux/psobjs.c (ps_table_add): Modified increment loop in order to implement exponential behaviour. 2002-11-01 David Turner <david@freetype.org> Added PFR-specific public API.

(FT_EXPORT, FT_EXPORT_DEF, FT_DEBUG_LEVEL_ERROR, FT_DEBUG_LEVEL_TRACE, FT_DEBUG_MEMORY): Comment out definitions so that platform specific configuration file can override. * include/freetype/internal/ftstream.h: Include FT_SYSTEM_H. 2002-10-30 David Turner <david@freetype.org> * FreeType 2.1.3rc3 released. 2002-10-25 David Turner <david@freetype.org> * include/freetype/ftcache.h (FT_POINTER_TO_ULONG): New macro. (FTC_FACE_ID_HASH): Rewritten, using FT_POINTER_TO_ULONG. 2002-10-22 Giuseppe Ghibò <ghibo@mandrakesoft.com> * include/freetype/freetype.h (FT_Encoding): Fix entry for latin-2. 2002-10-07 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FT_Open_Face): Use `const' for `args' (suggested by Graham). * src/base/ftobjs.c (FT_Open_Face): Updated. (ft_input_stream_new): Ditto. 2002-10-05 David Turner <david@freetype.org> Adding support for embedded bitmaps to the PFR driver, and rewriting its kerning loader/handler to use all kerning pairs in a physical font (and not just the first item). * src/pfr/pfr.c: Include `pfrsbit.c'. * src/pfr/pfrgload.c: Include `pfrsbit.h'. * src/pfr/pfrload.c (pfr_extra_item_load_kerning_pairs): Rewritten.

Type 1 faces supplied by PostScript interpreters like GhostScript will typically not provide any charstrings at load time, so this is essential if they are to work. 2002-08-01 Graham Asher <graham.asher@btinternet.com> Modified incremental loading interface to be closer to David's preferences. The header freetype.h is not now affected, the interface is specified via an FT_Parameter, the pointer to the interface is hidden in an internal part of the face record, and all the definitions are in ftincrem.h. * include/freetype/freetype.h [FT_CONFIG_OPTION_INCREMENTAL]: Removed. * include/freetype/internal/ftobjs.h [FT_CONFIG_OPTION_INCREMENTAL]: Include FT_INCREMENTAL_H.

The FT_Incremental_Interface structure, defined in freetype.h, is designed to be passed to FT_Open_Face to provide callback functions to obtain glyph recipes and metrics, for fonts like those passed from PostScript that do not necessarily provide all, or any, glyph information, when first opened. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL): New configuration macro to enable incremental face loading. By default it is not defined. * include/freetype/freetype.h (FT_Basic_Glyph_Metrics, FT_Get_Glyph_Data_Func, FT_Get_Glyph_Metrics_Func, FT_Incremental_Interface_Funcs, FT_Incremental_Interface) [FT_CONFIG_OPTION_INCREMENTAL]: New.

They provide a new API (FT_Get_X11_Font_Format) to retrieve an X11-compatible string describing the font format of a given face. This was put in a new optional base source file, corresponding to a new public header (named FT_XFREE86_H since this function should only be used within the XFree86 font server IMO). * include/freetype/config/ftheader.h (FT_XFREE86_H): New macro (not documented yet). * src/base/fttype1.c: New file, providing two new API functions (FT_Get_PS_Font_Info and FT_Has_PS_Glyph_Names). * include/freetype/t1tables.h: Updated. * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Updating build control files for the new files `ftxf86.c' and `fttype1.c' in src/base. * src/pshinter/pshglob.c (psh_blues_scale_zones): Fixed a bug that prevented family blue zones substitution from happening correctly. * include/freetype/ftbdf.h FT_Get_BDF_Charset_ID): Adding documentation comment. 2002-05-28 Werner Lemberg <wl@gnu.org> * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT but FT_STREAM_READ. Declare `stream' variable. * src/bdf/bdflib.c (_bdf_parse_glyphs): Replace floating point math with calls to `FT_MulDiv'. 2002-05-28 David Turner <david@freetype.org> Fixing the SFNT name table loader to support various buggy fonts. It now ignores empty name entries, entries with invalid pointer Offsets and certain fonts containing tables with broken `storageOffset' fields. Name strings are now loaded on demand, which reduces the memory requirements for a given FT_Face tremendously (for example, the name table of Arial.ttf is about 10Kb and contains 70 names). This is a temporary fix. The whole name table loader and interface will be rewritten in a much more cleanly way shortly, once CSEH have been introduced in the sources. * include/freetype/internal/tttypes.h (TT_NameEntryRec): Change type of `stringOffset' to FT_ULong. (TT_NameTableRec): Change type of `numNameRecords' and `storageOffset' to FT_UInt.

Make code more robust. * src/sfnt/sfobjs.c (TT_NameEntry_ConvertFunc): New typedef. (tt_face_get_name): Use it. Make code more robust. * src/sfnt/ttload.c (TT_Load_Names): Use `static' for arrays. Handle invalid `storageOffset' data better. Set length fields to zero for invalid or ignored data. Remove code within FT_DEBUG_LEVEL_TRACE. (TT_Free_Names): Updated. 2002-05-24 Tim Mooney <enchanter@users.sourceforge.net> * builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be rebuilt from sources. Set macro serial to 1, and use third argument to AC_DEFINE for our two custom symbols, so ftconfig.in could one day be rebuilt with autoheader (not recommended now, ftconfig.in is a custom source file) 2002-05-22 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftheader.h (FT_BEZIER_H): Removed. (FT_BDF_H): New macro for accessing `ftbdf.h'. * src/type42/t42drivr.c (hexval): Fix typo. 2002-05-21 Martin Muskens <mmuskens@aurelon.com> * src/psaux/psobjs.c (T1Radix): New function. (t1_toint): Use it to handle numbers in radix format. * src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings): Add dummy for undocumented, obsolete opcode 15. 2002-05-21 David Turner <david@freetype.org> * src/bdf/bdflib.c: Removed compiler warning, and changed all tables to the `static const' storage specifier (instead of simply `static'). * src/type42/t42drivr.c (hexval): Use more efficient code. Removing compiler warnings. * src/bdf/bdfdrivr.c: Removing compiler warnings. * include/freetype/internal/ftbdf.h, src/base/ftbdf.c, src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk (FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings from a face. This is much cleaner than accessing the internal types `BDF_Public_Face' defined in FT_INTERNAL_BDF_TYPES_H. 2002-05-21 Werner Lemberg <wl@gnu.org> * src/bdf/README: Mention Microsoft's SBIT tool. * src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/winfonts/winfnt.c, src/type42/t42drivr.c, src/bdf/bdfdrivr.c [FT_CONFIG_OPTION_DYNAMIC_DRIVERS]: Completely removed. It has been never used. 2002-05-21 Roberto Alameda <ojancano@geekmail.de>. * src/type42/t42drivr.c: s/T42_ENCODING_TYPE_/T1_ENCODING_TYPE_/. (parse_font_matrix): Remove unnecessary code. (parse_sfnts): Initialize some variables. (t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use ft_module_driver_has_hinter conditionally.

The culprit was a single-bit flag that wasn't set correctly by the TrueType glyph loader. * src/otlayout/otlayout.h, src/otlayout/otlbase.c, src/otlayout/otlbase.h, src/otlayout/otlconf.h, src/otlayout/otlgdef.c, src/otlayout/otlgdef.h, src/otlayout/otlgpos.c, src/otlayout/otlgpos.h, src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otljstf.c, src/otlayout/otljstf.h, src/otlayout/otltable.c, src/otlayout/otltable.h, src/otlayout/otltags.h: New OpenType Layout source files.

The charmap validator now accepts overlapping ranges in format 4 charmaps. * src/sfnt/ttcmap0.c (tt_cmap4_char_index): Switched to a binary search algorithm. Certain fonts contain more than 170 distinct segments! * include/freetype/config/ftstdlib.h: Adding an alias for the `exit' function. This will be used in the near future to panic in case of unexpected exception (which shouldn't happen in theory). * include/freetype/internal/fthash.h, src/base/fthash.c: New files. This is generic implementation of dynamic hash tables using a linear algorithm (to get rid of `stalls' during resizes). In the future this will be used in at least three parts of the library: the cache sub-system, the object sub-system, and the memory debugger. * src/base/Jamfile: Updated. * include/freetype/internal/internal.h (FT_INTERNAL_HASH_H, FT_INTERNAL_OBJECT_H): New macros. * include/freetype/internal/ftcore.h: New file to group all new definitions related to exception handling and memory management.

(psh1_print_zone): This. * include/freetype/freetype.h, include/freetype/internal/ftobjs.h, src/base/ftobjs.c: Adding the new FT_Library_Version API to return the library's current version in dynamic links. * src/base/ftinit.c (FT_Init_FreeType): Updated. 2002-03-06 Werner Lemberg <wl@gnu.org> * src/pshinter/pshglob.h (PSH_DimensionRec): s/std/stdw/. * src/pshinter/pshglob.c (psh_global_scale_widths, psh_dimension_snap_width, psh_globals_destroy, psh_globals_new): Ditto. 2002-03-05 David Turner <david@freetype.org> * src/type1/t1objs.c (T1_Face_Init), src/cff/cffobjs.c (CFF_Face_Init), src/cid/cidobjs.c (CID_Face_Init): Removing the bug that returned global BBox values in 16.16 fixed format (instead of integer font units). * src/cid/cidriver.c (cid_get_postscript_name): Fixed a bug that caused the CID driver to return Postscript font names with a leading slash (`/') as in `/MOEKai-Regular'. * src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name), src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so that it accepts broken fonts like `foxjump.ttf', which made FreeType crash when trying to load them. Also improved the name table parser to be able to load Windows-encoded entries before Macintosh or Unicode ones, since it seems some fonts don't have reliable values here anyway. * include/freetype/internal/psnames.h: Add typedef for `PSNames_Service'. 2002-03-05 Werner Lemberg <wl@gnu.org> * builds/unix/aclocal.m4, builds/unix/ltmain.sh: Update to libtool 1.4.2. Apply a small patch for AIX to make shared libraries work (this patch is already in the CVS version of libtool). * builds/unix/config.sub, builds/unix/config.guess: Updated to recent versions. * builds/unix/configure.ac: Fix typo (AC_CONFIG_FILE->AC_CONFIG_FILES). * builds/unix/configure: Regenerated. 2002-02-28 David Turner <david@freetype.org> * include/freetype/ftconfig.h: Changed `FT_LOCAL xxxx' to `FT_LOCAL( xxxx )' everywhere in the source. The same goes for `FT_LOCAL_DEF xxxx' which is translated to `FT_LOCAL_DEF( xxxxx )'. * include/freetype/freetype.h (FREETYPE_MINOR, FREETYPE_PATCH): Changing version to 2.1.0 to indicate an unstable branch. Added the declarations of FT_Get_First_Char and FT_Get_Next_Char. * src/base/ftobjs.c: Implement FT_Get_First_Char and FT_Get_Next_Char. * include/freetype/t1tables.h: Renaming structure types. This typedef T1_Struct_ { } T1_Struct; becomes typedef PS_StructRec_ { } PS_StructRec, *PS_Struct; typedef PS_StructRec T1_Struct; /* backward compatibility */ Hence, we increase the coherency of the source code by effectively using the `Rec' prefix for structure types. 2002-02-27 David Turner <david@freetype.org> * src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the names table loader. Invalid individual name entries are now handled correctly. This allows the loading of very buggy fonts like `foxjump.ttf' without allocating tons of memory and causing crashes. * src/otlayout/otlcommon.h, src/otlayout/otlcommon.c: Adding (still experimental) code for OpenType Layout tables validation and parsing. * src/type1/t1cmap.h, src/type1/t1cmap.c: Adding (still experimental) code for Type 1 charmap processing. * src/sfnt/ttcmap0.c: New file. It contains a new, still experimental SFNT charmap processing support. * include/freetype/internal/ftobjs.h: Adding validation support as well as internal charmap object definitions (FT_CMap != FT_CharMap). 2002-02-24 David Turner <david@freetype.org> * Renaming stream functions to the FT_<Subject>_<Action> scheme: FT_Seek_Stream => FT_Stream_Seek FT_Skip_Stream => FT_Stream_Skip FT_Read_Stream => FT_Stream_Read FT_Read_Stream_At => FT_Stream_Read_At FT_Access_Frame => FT_Stream_Enter_Frame FT_Forget_Frame => FT_Stream_Exit_Frame FT_Extract_Frame => FT_Stream_Extract_Frame FT_Release_Frame => FT_Stream_Release_Frame FT_Get_XXXX => FT_Stream_Get_XXXX FT_Read_XXXX => FT_Stream_Read_XXXX FT_New_Stream( filename, stream ) => FT_Stream_Open( stream, filename ) (The function doesn't create the FT_Stream structure, it simply initializes it for reading.) FT_New_Memory_Stream( library, FT_Byte* base, size, stream ) => FT_Stream_Open_Memory( stream, const FT_Byte* base, size ) FT_Done_Stream => FT_Stream_Close FT_Stream_IO => FT_Stream_IOFunc FT_Stream_Close => FT_Stream_CloseFunc ft_close_stream => ft_ansi_stream_close (in base/ftsystem.c only) ft_io_stream => ft_ansi_stream_io (in base/ftsystem.c only) * src/base/ftutil.c: New file. Contains all memory and list management code (previously in `ftobjs.c' and `ftlist.c', respectively). * include/freetype/internal/ftobjs.h: Moving all code related to glyph loaders to ... * include/freetype/internal/ftgloadr.h: This new file. `FT_GlyphLoader' is now a pointer to the structure `FT_GlyphLoaderRec'. (ft_glyph_own_bitmap): Renamed to ... (FT_GLYPH_OWN_BITMAP): This. * src/base/ftobjs.c: Moving all code related to glyph loaders to ... * src/base/ftgloadr.c: This new file. 2002-02-22 Werner Lemberg <wl@gnu.org> * include/freetype/internal/ftdebug.h (FT_Trace): Remove comma in enum to avoid compiler warnings. 2002-02-21 David Turner <david@freetype.org> Modified the debug sub-system initialization. Trace levels can now be specified within the `FT2_DEBUG' environment variable. See the comments within `ftdebug.c' for more details. * src/base/ftdebug.c: (FT_SetTraceLevel): Removed. (ft_debug_init): New function. (ft_debug_dummy): Removed. Updated to changes in ftdebug.h * include/freetype/internal/ftdebug.h: Always define FT_DEBUG_LEVEL_ERROR if FT_DEBUG_LEVEL_TRACE is defined. (FT_Assert): Renamed to ... (FT_ASSERT): This. Some stuff from ftdebug.h has been moved to ... * include/freetype/internal/fttrace.h: New file, to define the trace levels used for debugging. It is used both to define enums and toggle names for FT2_DEBUG. * include/freetype/internal/internal.h: Updated. * src/base/ftobjs.c, src/base/ftstream.c: Updated. * include/freetype/internal/ftextend.h, src/base/ftextend.c: Removed. Both files are now completely obsolete. * src/base/Jamfile, src/base/rules.mk: Updated. * include/freetype/fterrors.h: Adding `#undef FT_ERR_CAT' and `#undef FT_ERR_XCAT' to avoid warnings with certain compilers (like LCC). * src/pshinter/pshalgo2.c (print_zone): Renamed to ... (psh2_print_zone): This to avoid errors during compilation of debug library. * src/smooth/ftgrays.c (FT_COMPONENT): Change definition to as `trace_smooth'. 2002-02-20 David Turner <david@freetype.org> * README: Adding `devel@freetype.org' address for bug reports. 2002-02-20 Werner Lemberg <wl@gnu.org> * builds/unix/install.mk (check): New dummy target. (.PHONY): Add it. 2002-02-19 Werner Lemberg <wl@gnu.org> * builds/freetype.mk (FT_CFLAGS): Use $(INCLUDE_FLAGS) first. * src/cache/ftccache.c (ftc_cache_resize): Mark `error' as unused to avoid compiler warning. * src/cff/cffload.c (CFF_Get_String): Ditto. * src/cff/cffobjs.c (CFF_StrCopy): Ditto. * src/psaux/psobjs.c (PS_Table_Done): Ditto. * src/pcf/pcfread.c (pcf_seek_to_table_type): Ditto. * src/sfnt/sfdriver.c (get_sfnt_postscript_name): Ditto.
