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 <david@freetype.org> * 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 <wl@gnu.org> * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): Remove compiler warning. 2007-01-02 David Turner <david@freetype.org> * src/sfnt/sfobjs.c: Add documentation comment. 2006-12-31 Masatake YAMATO <jet@gyve.org> * 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 <david@freetype.org> * 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 <anders@kaseorg.com> * src/base/ftlcdfil.c (FT_Library_SetLcdFilter) [FT_FORCE_LIGHT_LCD_FILTER]: Fix typo. 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * 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 <mpsuzuki@hiroshima-u.ac.jp> * 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 <mpsuzuki@hiroshima-u.ac.jp> * 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 <mpsuzuki@hiroshima-u.ac.jp> * 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 <wl@gnu.org> * builds/toplevel.mk (version): Protect against `distclean' target. 2006-12-09 Werner Lemberg <wl@gnu.org> * 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 <wl@gnu.org> * builds/toplevel.mk (dist): Extract version number from freetype.h. 2006-12-08 Vladimir Volovich <vvv@vsu.ru> * src/tools/apinames (State): Remove final comma in structure -- xlc v5 under AIX 4.3 doesn't like this. 2006-12-07 David Turner <david@freetype.org> * 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 <wl@gnu.org> * src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c. 2006-12-01 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are encoded in UTF-16BE.

(af_latin_hints_compute_edges): Increase `segment_length_threshold' value and use `height' member for comparisons. (af_latin_hint_edges): Extend logging message. Improve handling of remaining edges. 2006-11-22 Werner Lemberg <wl@gnu.org> Fix Savannah bug #15553. * src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT program after a change from mono to grayscaling (and vice versa). Use correct constant for comparison to get `exec->grayscale'. 2006-11-18 Werner Lemberg <wl@gnu.org> 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 <david@freetype.org> * 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 <david@freetype.org> * 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'. (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering callback and update other fields. * src/smooth/ftsmooth.c (ft_smooth_render_generic) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update. 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 <david@freetype.org> * src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix typo which created a variable-used-before-initialized bug. 2006-11-07 Zhe Su <james.su@gmail.com> * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout also. 2006-11-03 Werner Lemberg <wl@gnu.org> * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'. 2006-11-02 David Turner <david@freetype.org> 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 <wl@gnu.org> * 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 <zsu@novell.com> * 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 <david@freetype.org> 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) <Populate>: 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. (psh_glyph_interpolate_normal_points): Rewrite for efficiency. 2006-10-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (FT_New_Face_From_FOND): Initialize variable `error' with FT_Err_Ok. 2006-10-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * docs/INSTALL.CROSS: New document file for cross-building. * builds/unix/configure.raw: Preliminary cross-building support. Find native C compiler and pass it by CC_BUILD, and find suffix for native executable and pass it by EXEEXT_BUILD. 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 <wl@gnu.org> * 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 <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw (FT2_EXTRA_LIBS): New variable.

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 the second part of Savannah bug #16590. 2006-05-18 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again. 2006-05-17 David Turner <david@freetype.org> 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. (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out. [TEST]: Remove. * src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test code. * src/autofit/afhints.c (af_axis_hints_new_segment): Don't call `FT_ZERO' (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten. (af_glyph_hints_reload: Rewrite recognition of weak points. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move constant values out of the loops. * src/autofit/aftypes.h: Updated. * src/base/ftcalc.c (FT_MulFix): Use inline assembler code. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector product to get orientation. * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function. (FT_Stream_OpenGzip): Use it to handle small files directly in memory. * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode): Improve performance. * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and `limit'. (TT_Load_Glyph_Header, TT_Load_Simple_Glyph, TT_Load_Composite_Glyph): Updated. Add threshold to protect against exceedingly large values of number of contours. Speed up by reducing the number of loops. * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold used to detect rogue clients from 4 to 16. This is to prevent some segmentation faults with fonts like `KozMinProVI-Regular.otf' which comes from the Japanese Adobe Reader Asian Font pack. 2007-05-17 Werner Lemberg <wl@gnu.org> * src/cff/cffload.c (cff_font_done): Deallocate subfont array. This fixes the first part of Savannah bug #16590. 2006-05-16 Werner Lemberg <wl@gnu.org> * docs/PROBLEMS: Updated icl issues. ---------------------------------------------------------------------------- Copyright 2006, 2007 by David Turner, Robert Wilhelm, and Werner Lemberg.
