Werner Lemberg 3f542498 2013-09-11T23:08:31 [autofit] Improve Hebrew rendering. This change introduces a new blue zone property `AF_BLUE_PROPERTY_LATIN_LONG' to make the auto-hinter ignore short top segments. * src/autofit/afblue.dat: Fix Hebrew blue strings. Use AF_BLUE_PROPERTY_LATIN_LONG for AF_BLUE_STRING_HEBREW_TOP. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_LONG): New macro. * src/autofit/afblue.c, src/autofit/afblue.h: Updated. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle `AF_LATIN_IS_LONG_BLUE'. * src/autofit/aflatin.h (AF_LATIN_IS_LONG_BLUE): New macro.
Werner Lemberg 00ea2a13 2013-09-03T11:33:10 [doc] s/which/that/ where appropriate. Note that this is a try by a non-native English speaker whose mother language (German) doesn't have this distinction at all...
Werner Lemberg 504f5b4a 2013-09-02T22:08:12 Fix Savannah bug #39905 (documentation only).
Werner Lemberg 85a7fdf3 2013-08-29T21:03:05 [sfnt] Fix frame access while reading WOFF table directory. * src/sfnt/sfobjs.c (woff_open_font): Using single memory frame while reading the directory entries for the whole loop.
Werner Lemberg d689d1cf 2013-08-29T17:53:40 Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'. (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.
Werner Lemberg dc240524 2013-08-29T17:53:24 [gzip] New function `FT_Gzip_Uncompress'. This is modeled after zlib's `uncompress' function. We need this for WOFF support. * include/freetype/ftgzip.h, src/gzip/ftgzip.c (FT_Gzip_Uncompress): New function. * src/gzip/rules.mk: Rewrite to better reflect dependencies.

Behdad Esfahbod bd3849e7 2013-08-27T21:43:38 FT_Open_Face: Improve external stream handling. If the font's `clazz->init_face' function wants to swap to new stream, handling of whether original stream was external could result to either memory leak or double free. Mark externality into face flags before calling `init_face' such that the clazz can handle external streams properly. * src/base/ftobjs.c (FT_Open_Face): Move code to set FT_FACE_FLAG_EXTERNAL_STREAM to... (open_face): This function.
Werner Lemberg bcd8c0b0 2013-08-27T21:36:03 Remove `FT_SqrtFixed' function. It's no longer used. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c: Do it.

Werner Lemberg 5e53db25 2013-08-27T18:37:39 [autofit] While tracing, report script names instead of ID values. * src/autofit/afglobal.c (af_script_names) [FT_DEBUG_LEVEL_TRACE]: New array. * src/autofit/afglobal.h: Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_hint_edges): Use `af_script_names'. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hint_edges): Ditto.
Werner Lemberg 278f64b3 2013-08-26T20:20:03 [autofit] Report used script while hinting a glyph. * src/autofit/afcjk.c (af_cjk_hint_edges), src/autofit/aflatin.c (af_latin_hint_edges): Implement it.
Werner Lemberg 371f5c3b 2013-08-26T20:11:24 [autofit] Add support for Hebrew script. * src/autofit/afblue.dat: Add blue strings for Hebrew. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.c (af_hebr_uniranges): New array. (af_hebr_script_class): New script. * src/autofit/aflatin.h, src/autofit/afscript.h: Updated.
Werner Lemberg 098121db 2013-08-26T18:54:05 [autofit] Improve tracing messages. * src/autofit/afcjk.c (af_cjk_metrics_init_widths): Mention script ID in tracing message. (af_cjk_metrics_init_blues): Initialize `axis' outside of the inner loop. Improve tracing messages. (af_cjk_hint_edges) [FT_DEBUG_LEVEL_TRACE]: New variable `num_actions' to count hinting actions. Improve tracing messages. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Mention script ID in tracing message. (af_latin_metrics_init_blues, af_latin_hint_edges): Improve tracing messages.
Werner Lemberg ffee64af 2013-08-26T12:55:48 Better tracing of loaded glyphs. Previously, the loading of a glyph was traced at level 4, if at all. With this change, all font loading routines emit a tracing message at level 1, making it easier to select tracing output (for example using F2_DEBUG="any:1 afhints:7 aflatin:7"). * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message. * src/cff/cffdrivr.c (cff_glyph_load): Ditto. * src/cff/cffgload.c (cff_decoder_prepare): Improve tracing messages. * src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing message. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. * src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto.
Werner Lemberg 33655a96 2013-08-26T09:58:50 [autofit] Fix script selection. * src/autofit/afglobal.c (af_face_globals_get_metrics): Use `AF_SCRIPT_DFLT', not value 0. Simplify code. * src/autofit/afscript.h: Sort by script name.

(AF_CJK_BLUE_TYPE_*): Removed. (af_cjk_metrics_init_blues): Replace AF_CJK_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Instead of three dimensions (as used in the old blue string array) we now use properties to do the same, saving one loop nesting level. * src/autofit/afcjk.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE, AF_CJK_IS_RIGHT_BLUE): New macros, to be used in `af_cjk_metrics_init_blues'. (AF_CJK_BLUE_IS_RIGHT): Remove this now redundant enum value. (AF_CJK_BLUE_IS_TOP): Renamed to... (AF_CJK_BLUE_TOP): This. (AF_CJK_MAX_BLUES): Remove. (AF_CJKAxisRec): Updated.
Werner Lemberg 5c4a23a4 2013-08-25T19:29:07 [autofit] Typo. * src/autofit/afblue.hin, src/autofit/afblue.c (GET_UTF8_CHAR): Use cast.
Werner Lemberg 306f8c5d 2013-08-25T13:07:08 [autofit] Synchronize `cjk' with `latin' module (and vice versa). * src/autofit/afcjk.c (af_cjk_metrics_init_widths): Add tracing messages. (af_cjk_metrics_init_blues): Don't pass blue string array as argument but use the global array directly. Use `outline' directly. Update and add tracing messages. (af_cjk_metrics_init): Simplify code. (af_cjk_metrics_scale_dim): Improve tracing message. (af_cjk_metrics_scale): Synchronize. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues): Improve and add tracing messages.

(af_latin_metrics_init_blues): Replace AF_LATIN_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Use `AF_LATIN_IS_SMALL_TOP_BLUE' macro. * src/autofit/aflatin.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_LATIN_IS_TOP_BLUE): Updated definition. (AF_LATIN_IS_SMALL_TOP_BLUE): New macro. (AF_LATIN_MAX_BLUES): Remove. (AF_LatinAxisRec): Updated.

(AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/autofit.c: Include `afblue.c'. * src/autofit/afcjk.c (af_hani_script_class), src/autofit/afdummy.c (af_dflt_script_class), src/autofit/afindic.c (af_deva_script_class), src/autofit/aflatin.c (af_latn_script_class), src/autofit/aflatin2.c (af_ltn2_script_class): Updated. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `afblue.c'.
Werner Lemberg 8b8be783 2013-08-25T08:01:41 [autofit] Introduce data file for blue strings. The idea is to have a central file which gets processed by a Perl script to create proper `.c' and `.h' files using templates. There are two other reasons to do that: . The data file should be easily readable. We use UTF-8 encoding which then gets converted to single bytes. . Since the number of supported scripts will increase soon, the current usage of blue string arrays is a waste of space. Using the Perl script it is possible to imitate jagged arrays, defining enumeration constants as offsets into the arrays. This commit only adds files without changing any functionality. * src/autofit/afblue.dat: New data file. * src/tools/afblue.pl: New Perl script for processing `afblue.dat'. * src/autofit/afblue.cin, src/autofit/afblue.hin: New template files for... * src/autofit/afblue.c, src/autofit/afblue.c: New source files. To avoid a dependency on Perl, we add them too.

John Tytgat 9bcfab87 2013-08-06T08:55:19 Fix Savannah bug #39702. * src/cff/cffload.c (cff_index_get_pointers): Check for `cur_offset != 0'; this stronger test is mandated by the CFF specification. Fix test for INDEX structures which have one or more empty entries at the end.
Werner Lemberg a32682f1 2013-08-06T00:21:46 Fix gcc pragmas, part 2. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): `#pragma gcc diagnostic {push,pop}' has been introduced with gcc version 4.6.
Werner Lemberg 69e524d5 2013-08-05T23:38:32 Fix gcc pragmas. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): Older gcc versions don't accept diagnostic pragmas within a function body.
Werner Lemberg 9e6de36a 2013-08-05T16:37:21 Fix Savannah bug #39700. * builds/unix/ftconfig.h: Synchronize with `include/freetype/config/ftconfig.h'. * builds/vms/ftconfig.h: Ditto. Make the differences to the master `ftconfig.h' file as small as possible for easier maintainance.

Werner Lemberg cc25e3ae 2013-08-05T08:46:15 [autofit] Improve handling of `near' points. Points which are very near to each other are now marked as such. The `weak' flag is then computed by using the `in' vector of the first and the `out' vector of the last point of a group of near points. For example, this fixes the rendering of glyph `Oslash' in `Roboto-Thin.ttf'. * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. * src/autofit/afhints.c (af_glyph_hints_reload): Introduce the heuristic value `near_limit' to decide whether the current point is near to the previous one, then set `AF_FLAG_NEAR' accordingly. Store good `in' vector (of last non-near point) in `last_good_in_{x,y}' and use it as an argument to `ft_corner_is_flat' if necessary.

Werner Lemberg 72f5ff5b 2013-07-31T22:49:29 [autofit] Introduce `writing systems'. This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts. For example, the `latin' writing system (in file `aflatin.c') is able to support scripts like Latin, Cyrillic, Armenian, etc., which can be handled similarly. Scripts are now named using four-letter OpenType tags. * src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members to... (AF_WritingSystemClassRec): This new structure.

Behdad Esfahbod 21c32b08 2013-07-25T21:53:18 Add FT_FACE_FLAG_COLOR and FT_HAS_COLOR. Also disambiguate Google's color bitmap tables. * include/freetype/freetype.h (FT_FACE_FLAG_COLOR, FT_HAS_COLOR): New macros. * include/freetype/internal/tttypes.h (TT_SbitTableType): Add TT_SBIT_TABLE_TYPE_CBLC. * src/sfnt/sfobjs.c (sfnt_load_face): Handle FT_FACE_FLAG_COLOR. * src/sfnt/ttsbit.c (tt_face_load_sbit, tt_face_load_strike_metrics, tt_face_load_sbit_image): Handle TT_SBIT_TABLE_TYPE_CBLC.
suzuki toshiya b4725cb7 2013-07-24T14:25:39 [sfnt] Fix for `make multi' target. * src/sfnt/pngshim.c (Load_SBit_Png): Use FT_LOCAL_DEF().
Werner Lemberg 6a7df625 2013-07-20T10:48:37 * docs/INSTALL.GNU: Updated.
Behdad Esfahbod ff269528 2013-07-20T08:02:39 [sfnt] Fix `sbix' table version handling. * src/sfnt/ttsbit.c (tt_face_load_sbit) [TT_SBIT_TABLE_TYPE_SBIX]: USHORT version numbers are to be considered as `minor'.
Werner Lemberg 05c1421f 2013-07-19T23:11:23 [autofit] Fix segment classification for blue zones. The old code (essentially unchanged since the very beginning) incorrectly handled this configuration x -o- x / \ / \ / \ o o as flat and this o o / / x| x| | | o---------------o as round. (`o' and `x' are on and off points, respectively). This is a major change which should improve the rendering results enormously for many TrueType fonts, especially in the range approx. 20-40ppem, fixing the appearance of many overshoots. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Look at the first and last points of the segment, not the points right before and after.
Behdad Esfahbod 778a7e6a 2013-07-19T14:28:28 [sfnt] `sbix' fix-ups. * src/sfnt/sfobjs.c (sfnt_load_face): Apple's `sbix' color bitmaps are rendered scaled and then the `glyf' outline rendered on top. We don't support that yet, so just ignore the `glyf' outline and advertise it as a bitmap-only font. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) [TT_SBIT_TABLE_TYPE_SBIX]: Return metrics in 26.6 units. (tt_face_load_sbix_image): Typo.
Werner Lemberg 01705395 2013-07-18T13:13:12 [sfnt] Add support for Apple's `sbix' color bitmap table. * include/freetype/internal/tttypes.h (TT_SBit_MetricsRec): Widen fields to FT_Short and FT_UShort, respectively. (TT_SBitTableType): New enumeration. (TT_FaceRec): Add `sbit_table_type' field. * include/freetype/tttags.h (TTAG_sbix): New macro. * src/sfnt/pngshim.c (Load_SBit_Png): Pass a more generic FT_GlyphSlot argument instead FT_Bitmap. Add flag to control map and metrics handling. Update all users. * src/sfnt/ttsbit.c: Include `ttmtx.h'. (tt_face_load_eblc): Renamed to... (tt_face_load_sbit): This. Handlic `sbix' bitmaps. (tt_face_free_eblc): Renamed to... (tt_face_load_sbit): This. Updated. (tt_face_load_strike_metrics): Handle `sbix' bitmaps. (tt_face_load_sbix_image): New function.

(tt_sbit_decoder_load_bitmap) [!FT_CONFIG_OPTION_USE_PNG]: Better handle formats 17-19. Move color to grayscale conversion to... (tt_face_load_sbit_image): Here. Handle `sbix' bitmaps. * src/sfnt/pngshim.h: Updated. * src/sfnt/ttsbit.h: Updated. * src/sfnt/sfdriver.c: Updated.
Werner Lemberg 274207eb 2013-07-18T12:38:57 [sfnt] Ignore invalid magic number in `head' or `bhed'. Other font engines seem to ignore it also. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/sfnt/ttload.c (check_table_dir): Don't abort but warn only if we have an invalid magic number.
Werner Lemberg 9a7951d9 2013-07-16T15:25:24 [smooth] Fix segfault caused by previous commit. * src/smooth/ftgrays.c (gray_set_cell): Always compute `ras.invalid'.
David Turner 89929ec6 2013-07-16T13:36:07 [smooth] Improve performance. Provide a work-around for an ARM-specific performance bug in GCC. This speeds up the rasterizer by more than 5%. Also slightly optimize `set_gray_cell' and `gray_record_cell' (which also improves performance on other platforms by a tiny bit (<1%). * src/smooth/ftgrays.c (FT_DIV_MOD): New macro. Use it where appropriate. (gray_record_cell, gray_set_cell, gray_move_to, gray_convert_glyph_inner): Streamline condition handling.
David Turner f66d48e9 2013-07-16T13:18:00 Add assembler code for TT_MulFix14 and TT_DotFix14. This patch provides slightly optimized versions for ARM, x86, and x86_64 CPUs if built with GCC. Also remove some dead code. * src/truetype/ttinterp.c (TT_MulFix14_arm, TT_MulFix14_long_long, TT_DotFix14_long_long): New functions.
David Turner b2890886 2013-07-16T12:52:18 Optimize FT_MulFix for x86_64 GCC builds. This patch provides an optimized `FT_MulFix' implementation for x86_64 machines when FreeType is built with GCC, or compatible compilers like Clang. Example: bin/ftbench -p -t 5 -s 14 -f 0008 Arial.ttf Before: Load 4.863 us/op Load_Advances (Normal) 4.816 us/op Load_Advances (Fast) 0.028 us/op Render 2.753 us/op Get_Glyph 0.463 us/op Get_CBox 0.077 us/op Get_Char_Index 0.023 us/op Iterate CMap 13.898 us/op New_Face 12.368 us/op Embolden 0.028 us/op Get_BBox 0.302 us/op After: Load 4.617 us/op Load_Advances (Normal) 4.645 us/op Load_Advances (Fast) 0.027 us/op Render 2.789 us/op Get_Glyph 0.460 us/op Get_CBox 0.077 us/op Get_Char_Index 0.024 us/op Iterate CMap 13.403 us/op New_Face 12.278 us/op Embolden 0.028 us/op Get_BBox 0.301 us/op * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h (FT_MulFix_x86_64): New function.
David Turner a5f33eeb 2013-07-16T12:40:03 Speed up ARMv7 support. When building for ARMv7 with thumb2 instructions, the optimized `FT_MulFix_arm' assembly routine was not being used. The reason for this is in the `ftconfig.h' header, namely: - The assembly routine uses the `smull' instruction which is not available when generating Thumb-1 machine code. It is available in Thumb-2 mode, though. - The header was written a long time ago before Thumb-2 became widely popular (e.g. with Android). So it simply doesn't use the assembly routine if the `__thumb__' built-in macro is defined. - When compiling in Thumb-2 mode, the compiler will define both `__thumb__' and `__thumb2__'. By checking for `(__thumb2__ || !__thumb__)', we ensure that the assembly routine is only avoided when generating Thumb-1 code. Given that this is performance-sensitive function, this improves `ftbench' as follows on a Galaxy Nexus: Before (us/op) After (us/op) - loading Arial.ttf glyphs at 14 ppem [1] Load 34.285 33.098 - same operation with the light auto-hinter [2] Load 31.317 29.590 - same operation without hinting [3] Load 6.143 5.376 - loading Arial.ttf advances at 14 ppem [4] Load_Advances (normal) 34.216 33.016 Load_Advances (fast) 0.176 0.176 [1] ftbench -t 5 -p -s 14 -b a -f 0008 Arial.ttf [2] ftbench -t 5 -p -s 14 -b a -r 1 -f 0028 Arial.ttf [3] ftbench -t 5 -p -s 14 -b a -f 000a Arial.ttf [4] ftbench -t 5 -p -s 14 -b b -f 0008 Arial.ttf * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER): Fix handling for ARMv7.

Werner Lemberg 841e49a7 2013-06-19T00:25:06 Update CHANGES; tag some auto-hinter properties as still experimental.
Werner Lemberg f56691a8 2013-06-18T10:17:48 Fix Savannah bug #39269. * src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Free memory in case of reacollocation failures.
Andrew Church 67cf7a88 2013-06-18T09:35:34 Fix Savannah bug #39266. If memory allocations fail at certain points while opening a font, FreeType can either crash due to a NULL dereference or leak memory. * include/freetype/internal/ftobjs.c (FT_Face_InternalRec, FT_LibraryRec): Make `refcount' a signed integer. If, for example, FT_Open_Face() fails in a memory allocation before the face's reference count is set to 1, a subsequent `FT_Done_Library' call would otherwise loop over `FT_Done_Face' 2^32 times before freeing the face. * src/base/ftobjs.c (open_face): Initialize `stream' and friends earlier. (FT_Open_Face) <Fail>: Behave correctly if `node' is NULL. (FT_Destroy_Module) <Fail>: Check that `renderer_clazz' is valid.
Werner Lemberg d7e3444b 2013-06-14T18:33:39 * src/smooth/ftgrays.c One final pragma to silence 64-bit MSVC.
Werner Lemberg 9d043dae 2013-06-13T10:45:56 Minor doc improvement. Suggested by Ulrich Eckhardt <ulrich.eckhardt@dominolaser.com>.
Dave Arnold cb23a628 2013-06-13T07:46:32 [cff] Add code to Adobe's engine to handle ppem > 2000. * src/cff/cffgload.c (cff_slot_load): If we get FT_Err_Glyph_Too_Big, retry unhinted and scale up later on.
Werner Lemberg 294ce11b 2013-06-12T23:33:11 Another try on pragmas. * include/freetype/internal/ftdebug.h: Move pragmas to... * include/freetype/internal/internal.h: ... this file since it gets included by all source files. * include/freetype/internal/ftserv.h: Remove pragma which has no effect.
Werner Lemberg 25b6e600 2013-06-12T11:06:34 * include/freetype/internal/ftdebug.h: Disable MSVC warning C4127. This partially undoes commit 3f6e0e0c.
Werner Lemberg c06889eb 2013-06-12T10:58:06 More compiler warning fixes. */*: Use cast to `FT_Bool' (or `Bool') where appropriate.

Werner Lemberg 5e094c6f 2013-06-10T14:59:21 [truetype] Improve handling of broken sbit advance widths. * src/truetype/ttgload.c (TT_Load_Glyph): Use the glyph's (scaled) `linearHoriAdvance' if the sbit's `horiAdvance' value is zero. Cf. font `Fixedsys Excelsior' v3.01 (FSEX300.ttf), glyph A, 16ppem.
Werner Lemberg a25ecfdd 2013-06-10T12:57:16 [sfnt] Improve embedded bitmap tracing. * src/base/ftobjs.c (FT_Request_Size): Move trace message regarding bitmap strike match to...
