Alexei Podtelezhnikov b6de8e66 2013-01-23T23:31:41 [base, truetype] New internal FT_Hypot function. * include/freetype/fttrigon.h (FT_Hypot): Declare it. * src/base/fttrigon.c (FT_Hypot): Define it. * src/truetype/ttgload.c (TT_Process_Composite_Component): Use it instead of explicit expressions. * src/truetype/ttinterp.c (Current_Ratio, Normalize): Use it instead of TT_VecLen. (TT_VecLen): Removed.
Werner Lemberg e0469372 2013-01-22T11:07:07 [truetype] Fix font height. * src/truetype/ttobjs.c (tt_size_reset): The Windows rendering engine uses rounded values of the ascender and descender to compute the TrueType font height.

David Turner 3a406127 2013-01-16T19:48:31 [truetype] Improve sub-pixel code. This patches fixes many issues with the ttsubpix implementation. 1. Data tables are defined, instead of declared, in the header, and thus copied into each source file that includes it. 2. These tables were defined as global, mutable, visible variables, and thus costing private RAM to every process that loads the library (> 50 KB / process, this is huge!). Additionally, this also made the library export the symbols completely needlessly. 3. Missing `sph_' and `SPH_' prefixes to some of the definitions. Note that this doesn't try to fix the incredibly inefficient storage format for the data tables used by the code. This one will require another pass in the future. * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS): Renamed to... (SPH_MAX_NAME_SIZE, SPH_MAX_CLASS_MEMBERS): This. Update all users. (SPH_TweakRule, SPH_ScaleRule): Decorate with `const' where appropriate. (Font_Class): Rename to... (SPH_Font_Class): This. Decorate with `const' where appropriate. * src/truetype/ttsubpix.h (scale_test_tweak, sph_test_tweak): Decorate arguments with `const' where appropriate. Move font tweaking tables to... * src/truetype/ttsubpic.c: This file and decorate them with `static' and `const' where appropriate. (X_SCALING_Rules, X_SCALING_RULES_SIZE): Renamed to... (spu_X_SCALING_Rules, SPH_X_SCALING_RULES_SIZE): This. Update all users.
Alexei Podtelezhnikov 0e0fdc5d 2013-01-12T23:05:55 [truetype] Improve accuracy of normalization of short vectors. Unit vector components are stored as 2.14 fixed-point numbers. In order to calculate all 14 bits accurately, a short vector to be normalized has to be upscaled to at least 14 bits before its length is calculated. This has been safe since accurate CORDIC algorithms were adopted. * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000.
Alexei Podtelezhnikov 081aba39 2013-01-12T22:36:37 [truetype] Kill very old vector normalization hacks. Back in the days, vector length calculations were not very accurate and the vector normalization function, Normalize, had to meticulously correct the errors for long vectors [commit b7ef2b096867]. It was no longer necessary after accurate CORDIC algorithms were adopted, but the code remained. It is time to kill it. * src/truetype/ttinterp.c (Normalize): Remove error compensation. (TT_VecLen): Remove any mention of old less accurate implementation.
Werner Lemberg 7d6dc907 2012-12-27T01:08:24 * src/truetype/ttgload.c (tt_loader_init): Add more tracing.

Werner Lemberg a9f6f85e 2012-12-17T09:08:09 Various compiler warning fixes. * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use `logical not' operator instead of negation. The idea is that `~' returns exactly the data type enforced by the cast to a pointer (be it 32bit or 64bit or whatever), while a negative integer has not this flexibility. * src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto. * src/truetype/ttgxvar.c (ALL_POINTS, TT_Get_MM_Var): Ditto. * src/type/t1load.c (T1_Get_MM_Var): Ditto.

Alexei Podtelezhnikov 65d65721 2012-12-10T06:59:29 [truetype] Scale F_dot_P down. The dot product between freeVector and projVector or cosine of the angle between these FT_F2Dot14 unit vectors used to be scaled up by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P. This patch scales the value down by 2^14 instead, which simplifies its use throughout the bytecode interpreter. This does not lead to the loss of precision because the lower bits are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8) for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. These vectors are stored as (0x4000,0) and (0x2666,0x3333) after rounding and F_dot_P is assigned 0x26660000. The lower bits were already lost while rounding the unit vector components. Besides code simplification, this change can lead to better performance when FT_MulDiv with the scaled-down F_dot_P is less likely to use the costly 64-bit path. We are not changing the type of F_dot_P to FT_F2Dot14 at this point. * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 bits and modify its use accordingly. (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify the use of F_dot_P field. * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary assignment of F_dot_P to its theoretical maximum in case we decide to scale back its type later.

Alexei Podtelezhnikov cece4d3b 2012-12-06T20:23:38 [truetype] Tweak the previous commit. * src/truetype/ttinterp.c (Current_Ratio): Put unit vector components as the second TT_MulFix14 arguments. This is required on 16-bit systems.
Alexei Podtelezhnikov 5ad05f97 2012-12-06T00:27:20 [truetype] Microoptimizations in bytecode interpreter. * src/truetype/ttinterp.c (TT_DivFix14): New macro. (Normalize): Use it here. (Current_Ratio): Use TT_MulFix14 instead of FT_MulDiv. (Ins_SHPIX): Cancel out two TT_MulFix14 calls.
Alexei Podtelezhnikov b50088bd 2012-12-05T23:05:47 [truetype] Cosmetic improvement in bytecode interpreter. * src/truetype/ttinterp.c: Use explicit calls to FT_MulDiv, FT_MulFix, and FT_DivFix instead of macros.

Alexei Podtelezhnikov 24e897db 2012-10-20T22:23:01 [truetype] Cheaper way to threshold angles between vectors. * src/truetype/ttinterp.c (Ins_ISECT): Thresholding tangent is a lot cheaper than thresholding sine.
Werner Lemberg 2df16761 2012-10-17T11:34:22 [truetype] Fix Savannah bug #37572. * src/truetype/ttinterp.c (Ins_ISECT): Use angle between vectors to avoid grazing intersections. The previous threshold was too coarse, incorrectly rejecting short but valid vectors.

Infinality 79e36bae 2012-06-18T10:36:06 [truetype] Support subpixel hinting. This is the large, famous `Infinality' patch to support ClearType bytecode which has been available from http://www.infinality.net/blog/ for some time, and which has been refined over the last years. While still experimental, it is now mature enough to be included directly into FreeType. Most of the code is based on the ClearType whitepaper written by Greg Hitchcock http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx which gives a detailed overview of the necessary changes to the Microsoft rasterizer so that older fonts are supported. However, a lot of details are still missing, and this patches provides a framework to easily handle rendering issues down to the glyph level of certain fonts. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. * src/truetype/ttsubpix.c: New file, providing code to handle `tweaks', this is, rules for certain glyphs in certain fonts (including wildcards) which need a special treatment. * src/truetype/ttsubpix.h: New file, holding the tweaking rules. * include/freetype/config/ftoption.h, src/devel/ftoption.h (TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro. * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros. * src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include `ttsubpix.c'. * src/truetype/ttgload.c: Include `ttsubpix.h'.

(TT_Process_Simple_Glyph): Compensate emboldening if necessary. (compute_glyph_metrics): Handle `compatible widths' option. (tt_loader_init): Handle ClearType GETINFO information bits. * src/truetype/rules.mk (TT_DRC_SRC): Updated. * src/truetype/ttinterp.c: Include `ttsubpix.h'. [Where necessary, changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.] (Direct_Move, Direct_Move_X): Extended. (Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45, SetSuperRound): Add parameter to handle the number of grid lines per pixel.

(Ins_GETINFO): Handle new ClearType bits. (TT_RunIns): Handle tweaks. * src/truetype/ttinterp.h: Updated. (SPH_TweakRule, SPH_ScaleRule): New structures for tweaks. (TT_ExecContextRec): Add members for subpixel hinting support. * src/truetype/ttobjs.h (TT_DefRecord): Add `inline_delta' member.
suzuki toshiya 6c7c3de1 2012-06-14T01:38:20 [truetype] Add new versions of NEC FA family to tricky font list. NEC FA family dated in 1996 have different checksum. Reported by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>; see http://lists.gnu.org/archive/html/freetype-devel/2012-06/msg00023.html * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): 4 sets of fpgm & prep table checksums for FA-Gothic, FA-Minchou, FA-RoundedGothicM, FA-RoundedGothicB are added.

suzuki toshiya 3c966818 2012-01-15T23:35:31 Fix redundant declaration warning in PIC mode. Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were designed to declare xxx_pic_{free,init} by themselves. Because these macros are used at the end of the module interface (e.g. ttdriver.c) and the wrapper source to build a module as a single object (e.g. truetype.c) includes the PIC file (e.g. ttpic.c) before the module interface, these macros are expanded AFTER xxx_pic_{free,init} body when the modules are built as single object. The declaration after the implementation causes the redundant declaration warnings, so the declarations are moved to module PIC headers (e.g. ttpic.h). Separating to other header files are needed for multi build. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): Remove class_##_pic_free and class_##_pic_init declarations. * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE): Ditto. * src/base/basepic.h: Insert a comment and fix coding style. * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, init}. * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, init}. * src/psnames/pspic.h: Declare psnames_module_class_pic_{free, init}. * src/raster/rastpic.h: Declare ft_raster{1,5}_renderer_class_pic_{free,init} * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. * src/smooth/ftspic.h: Declare ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.

Previously, FreeType misleadingly returned FT_Err_Unknown_File_Format if a module was missing (or a test was missing completely). * include/freetype/fterrdef.h (FT_Err_Missing_Module): Define. * src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c (cid_face_init), src/sfnt/sfobjs.c (sfnt_init_face), src/truetype/ttobjs.c (tt_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init, T42_Driver_Init): Updated. * src/type1/t1afm.c (T1_Read_Metrics), src/type/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Remove now redundant test for `psaux'.
Werner Lemberg f4ec60fd 2011-10-25T20:25:32 [truetype] Fix MD instruction for twilight zone. * src/truetype/ttinterp.c (Ins_MD): Without this fix, the MD instruction applied to original coordinates of twilight points always returns zero.
Werner Lemberg 9c98fbf6 2011-10-01T09:25:55 Handle some border cases. * include/freetype/config/ftstdlib.h (FT_USHORT_MAX): New macro. * src/base/ftbitmap.c (FT_Bitmap_Convert): Protect against invalid value of `target->rows'. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Add check for flex start. * src/raster/ftrend1.c (ft_raster1_render): Check `width' and `height'. * src/truetype/ttgxvar.c (TT_Vary_Get_Glyph_Deltas): Protect against invalid values in `localpoints' array.
Werner Lemberg bad0160c 2011-08-12T19:50:13 [truetype] Fix degenerate case in S{P,F,DP}VTL opcodes. * src/truetype/ttinterp.c (Ins_SxVTL): Handle p1 == p2 specially. (Ins_SDPVTL): Handle v1 == v2 specially.
Werner Lemberg 22e44e06 2011-08-05T09:57:17 [truetype] Remove incorrect comments.
Werner Lemberg f2573a06 2011-08-05T09:07:21 [truetype] Fix some comments in the bytecode interpreter. Thanks to Greg Hitchcock!
Steven Chu b0962ac3 2011-07-16T09:12:42 [truetype] Fix metrics on size request for scalable fonts. * src/truetype/ttdriver.c (tt_size_request): Fix copying metrics from TT_Size to FT_Size if scalable font.
Werner Lemberg f4b63326 2011-07-03T11:24:46 Fix previous commit. We want to unset FT_FACE_FLAG_SCALABLE only if there are bitmap strikes in the font. * src/truetype/ttobjs.c (tt_face_init): Implement it. * docs/CHANGES: Updated.
Just Fill Bugs 07598339 2011-07-02T18:41:36 Fix Savannah bug #33246. * src/truetype/ttobjs.c (tt_check_single_notdef): New function. (tt_face_init): Use it to test FT_FACE_FLAG_SCALABLE.
suzuki toshiya e62c876b 2011-06-15T02:48:33 Fix g++4.6 compiler warnings in module drivers. The background is same with previous commit. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Init `points'. (TT_Vary_Get_Glyph_Deltas): Init `delta_xy'. (TT_Get_MM_Var): Init `mmvar'. * src/type1/t1load.c (T1_Get_MM_Var): Ditto. * src/cff/cffdrivr.c (cff_ps_get_font_info): Init `font_info'. * src/cff/cffload.c (cff_index_get_pointers): Init `t'. (cff_font_load): Init `sub'. * src/cff/cffobjs.c (cff_size_init): Init `internal'. (cff_face_init): Init `cff'. * src/pfr/pfrload.c (pfr_extra_item_load_stem_snaps): Init `snaps'. * src/pcf/pcfread.c (pcf_get_properties): Init `properties'. (pcf_get_bitmaps): Init `offsets'. (pcf_get_encodings): Init `tmpEncoding'. * src/sfnt/ttload.c (tt_face_load_gasp): Init `gaspranges'. * src/sfnt/ttsbit.c (Load_SBit_Image): Init `components'. * src/cache/ftcmru.c (FTC_MruList_New): Init `node'. * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Init `zip' and `zip_buff'. * src/lzw/ftlzw.c (FT_Stream_OpenLZW): Init `zip'. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Init `zip'.
Daniel Zimmermann 3ad8f355 2011-05-24T06:22:32 Reduce warnings for MS Visual Studio 2010. * src/autofit/afhints.c (af_glyph_hints_get_num_segments, af_glyph_hints_get_segment_offset) [!FT_DEBUG_AUTOFIT]: Provide return value. * src/cff/cffgload.c (cff_slot_load): Add cast. * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Use proper loop variable type.
suzuki toshiya 58cb3593 2011-05-01T00:47:43 [truetype] Recalculate the sfnt table checksum always. * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate the sfnt table checksum even if non-zero value is writte in the TrueType font header. Some bad PDF generators write wrong values. For detail, see examples and benchmark tests of the latency by recalculation: http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00091.html http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00096.html
suzuki toshiya 1e89d15a 2011-04-30T17:55:57 [truetype] Register a set of tricky fonts, NEC FA family. * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Add 8 checksum sets for NEC FA family. For the tricky fonts without some tables (e.g. NEC FA fonts lack cvt table), extra check is added to assure that 0-length table in the registry is not included in the font.
suzuki toshiya 10385e37 2011-04-30T17:49:45 Remove unrequired `else' from ttobjs.c::tt_get_sfnt_checksum().
suzuki toshiya 89208861 2011-04-30T00:11:07 [truetype] Fix a bug in the sfnt table checksum getter. * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Check the return value of face->goto_table() correctly.
suzuki toshiya 86b7b2f6 2011-04-26T03:46:12 [truetype] Revert the reordering of trickyness checking. Trickyness check by the family name is faster than that by the checksum.
suzuki toshiya abc47aa1 2011-04-25T23:51:04 [truetype] Always check the checksum to identify tricky fonts. Some PDF generators mangle the family name badly, prioritize the check by the sfnt table checksums than the check by the family name. For sample PDF, see http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html * src/truetype/ttobjs.c (tt_check_trickyness): Exchange the order of tt_check_trickyness_family() and tt_check_trickyness_sfnt_ids().
Behdad Esfahbod 8c82ec5b 2011-04-21T08:21:37 Always ignore global advance. This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant, deprecated, and ignored. The new behavior is what every major user of FreeType has been requesting. Global advance is broken in many CJK fonts. Just ignoring it by default makes most sense. * src/truetype/ttdriver.c (tt_get_advances), src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics, tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph), src/truetype/ttgload.h: Implement it. * docs/CHANGES: Updated.
Werner Lemberg 01caf4a7 2011-03-23T05:19:59 * src/truetype/ttpload.c(tt_face_load_loca): Fix mismatch warning.
Werner Lemberg 6e3fee0b 2011-03-21T09:28:52 Typo.
Werner Lemberg 18931a5a 2011-02-01T07:08:43 [truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also. * src/truetype/ttgload.c (tt_loader_init): Handle `FT_LOAD_PEDANTIC'. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, tt_size_init_bytecode, tt_size_ready_bytecode): New argument to handle pedantic mode. * src/truetype/ttobjs.h: Updated.
Werner Lemberg f1a981b5 2011-01-31T22:26:53 [truetype] Protect jump instructions against endless loops. * src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error if offset is zero.
Werner Lemberg d6a213f8 2011-01-31T18:51:07 [truetype] Improve handling of invalid references. * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference error codes only if pedantic hinting is active. At the same time, try to provide sane values which hopefully allow useful continuation. Exception to this is CALL and LOOPCALL – due to possible stack corruption it is necessary to bail out.
Werner Lemberg 96f04564 2011-01-31T10:24:32 [truetype] Improve handling of stack underflow. * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, Ins_DELTAC): Exit with error only if `pedantic_hinting' is set. Otherwise, try to do something sane.
Werner Lemberg 91a97164 2011-01-30T20:12:54 Whitespace.
Werner Lemberg 0682251e 2011-01-30T16:38:09 * src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message.
LIU Sun-Liang c61b3596 2011-01-30T16:29:45 [truetype]: Fix behaviour of MIAP for invalid arguments. * src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in case of error.
Werner Lemberg dcdb3167 2011-01-18T07:35:26 [truetype] Fix handling of MIRP instruction. Thanks to Greg Hitchcock who explained the issue. * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with `>' since the description in the specification is incorrect. This fixes, for example, glyph `two' in font `Helvetica Neue LT Com 65 medium' at 15ppem.
Werner Lemberg f3ce2370 2011-01-03T07:11:54 */rules.mk: Handle `*pic.c' files.
Johnson Y. Yan 9073e7ce 2010-11-26T11:58:08 [truetype] Better multi-threading support. * src/truetype/ttinterp.c (TT_Load_Context): Reset glyph zone references.
Werner Lemberg 9871b849 2010-11-22T19:30:41 Some formatting and improvements of comments.
suzuki toshiya 9f5dd61b 2010-11-23T02:47:10 [truetype] Identify the tricky fonts by cvt/fpgm/prep checksums. Some Latin TrueType fonts are still expected to be unhinted. Fix Savannah bug #31645. * src/truetype/ttobjs.c (tt_check_trickyness): Divided to... (tt_check_trickyness_family): this checking family name, and (tt_check_trickyness_sfnt_ids): this checking cvt/fpgm/prep. (tt_get_sfnt_checksum): Function to retrieve the sfnt checksum for specified subtable even if cleared by lazy PDF generators. (tt_synth_sfnt_checksum): Function to calculate the checksum.
Werner Lemberg ec4372f5 2010-11-18T20:34:22 [truetype] Fix `loca' handling for inconsistent number of glyphs. Reported by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>. * src/truetype/ttpload.c (tt_face_load_loca): While sanitizing, handle case where `loca' is the last table in the font.
suzuki toshiya 46c371c2 2010-10-25T00:14:13 Replace "%lx" for memory address by "%p", LLP64 platforms. On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover the memory address (64-bit). Also the casts from the pointer type to long int should be removed to preserve the address correctly. * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". (End_Profile) Ditto. * src/truetype/ttinterp.c (Init_Context): Ditto.
Werner Lemberg 59eb9f8c 2010-10-12T07:49:17 Fix Savannah bug #31310. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Protect against invalid `runcnt' values.
Werner Lemberg 0edf0986 2010-10-06T11:52:27 [truetype] Improve error handling of `SHZ' bytecode instruction. Problem reported by Chris Evans <scarybeasts@gmail.com>. * src/truetype/ttinterp.c (Ins_SHZ): Check `last_point'.
suzuki toshiya 5edc2f33 2010-10-01T08:15:55 Fix Savannah bug #31040. * src/truetype/ttinterp.c (free_buffer_in_size): Remove. (TT_RunIns): Updated.
suzuki toshiya 643d49df 2010-09-20T01:07:57 [truetype] Sanitize the broken offsets in `loca'. * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the offset to the requested entry in `glyf' exceeds the end of the table, return offset=0, length=0. If `pos2', the offset to the next entry in `glyf' exceeds the end of the table, truncate the entry length at the end of `glyf' table. See Savannah bug #31040.
suzuki toshiya db053ec9 2010-09-17T23:20:00 [truetype] Don't duplicate size->twilight structure to be freed. * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate FT_GlyphZoneRec size->twilight to be freed. If duplicated, FT_FREE() erases the duplicated pointers only and leave original pointers. They can cause the double-free crash when the burst errors occur in TrueType interpreter and free_buffer_in_size() is invoked repeatedly. See Savannah bug #31040 for detail.
Werner Lemberg afd89d30 2010-09-15T13:02:35 Make bytecode debugging with FontForge work again. * src/truetype/ttinterp.c (TT_RunIns): Don't call `free_buffer_in_size' in case of error if a debugger is active.
Werner Lemberg 6abb9232 2010-09-14T09:02:10 Improve tracing messages. * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing message. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add tracing message. * src/truetype/ttgload.c (tt_loader_init): Add tracing message. * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if glyph doesn't fit into a small bitmap container.
