bf2ba9e3 | 2015-11-02 13:12:34 | [autofit] Implement darkening computation function. This is a crude adaption of the original `cf2_computeDarkening' function. * src/autofit/afloader.c (af_intToFixed, af_fixedToInt, af_floatToFixed): New macros, taken from `cf2fixed.h'. (af_loader_compute_darkening): New function. * src/autofit/afloader.h: Updated. | |
|
37c401ac | 2015-11-02 09:32:26 | [autofit] Add functions to get standard widths for writing systems. We need the computed standard horizontal and vertical widths for the emboldening calculation. This method provides a convenient way to extract it from writing-system-specific metrics structures, which all script definitions must implement. * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New function type. (AF_WritingSystemClassRec): New member `style_metrics_getstdw'. (AF_DEFINE_WRITING_SYSTEM_CLASS): Updated. * src/autofit/afcjk.c (af_cjk_get_standard_width): New function. (af_cjk_writing_system_class): Updated. * src/autofit/afdummy.c (af_dummy_writing_system_class): Updated. * src/autofit/afindic.c (af_cjk_get_standard_width): New function. (af_indic_writing_system_class): Updated. * src/autofit/aflatin.c (af_latin_get_standard_width): New function. (af_indic_writing_system_class): Updated. * src/autofit/aflatin.c (af_latin_get_standard_width): New function. (af_indic_writing_system_class): Updated. | |
|
b2a85ad3 | 2015-11-02 09:20:32 | [autofit] Extend `AF_FaceGlobalsRec' to hold emboldening data. * src/autofit/afglobal.h (AF_FaceGlobalsRec): Add fields. * src/autofit/afglobal.c (af_face_globals_new): Initialize new fields. (af_face_globals_free): Reset new fields. | |
|
d682e510 | 2015-11-02 09:06:36 | [autofit] Add stem-darkening properties. Actual code follows in a later commit. * include/freetype/ftautoh.h: Document `no-stem-darkening' and `darkening-parameters'. * src/autofit/afmodule.h: New fields `no_stem_darkening' and `darken_params'. * src/autofit/afmodule.c (af_property_set, af_property_get): Handle them. (af_autofitter_init): Initialize them. | |
 |
6bda921d | 2015-11-02 06:53:48 | [ftfuzzer] Update README file. | |
|
bcf618b2 | 2015-11-02 06:50:49 | [ftfuzzer] Add support for multiple files (patch #8779). Currently, libFuzzer only supports mutation of a single file. We circumvent this problem by using an uncompressed tar archive as multiple-file input for the fuzzer. This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing; a constructed tarball should contain a font file as the first element, and files to be attached as further elements. * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers. (archive_read_entry_data, parse_data): New functions. (LLVMFuzzerTestOneInput): Updated. * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom mutator for libFuzzer that can mutate tarballs in a sensible way. | |

|
009cc150 | 2015-10-31 17:52:56 | [sfnt] Handle infinite recursion in bitmap strikes (#46344). * src/sfnt/ttsbit.c (TT_SBitDecoder_LoadFunc, tt_sbit_decoder_load_bitmap, tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_png): Add argument for recursion depth.

|
f1c93439 | 2015-10-22 10:11:23 | [cff] Avoid overflow/module arithmetic. This modifies the addition of subroutine number to subroutine bias from unsigned to signed, but does not change any results. * src/cff/cf2ft.c (cf2_initGlobalRegionBuffer, cf2_initLocalRegionBuffer): Change variable names from (unsigned) `idx' to (signed) `subrNum', since it is not an index until after the bias is added. * src/cff/cf2ft.h: Updated. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>: Updated similarly. | |
|

|
8539915d | 2015-10-13 20:43:19 | [type1] Correctly handle missing MM axis names (#46202). * src/type1/t1load.c (T1_Get_MM_Var): Implement it. | |
|
58b61b6e | 2015-10-13 18:26:18 | [pcf] Quickly exit if font index < 0.

|
da34673e | 2015-10-10 10:21:27 | [truetype] More sanity tests for GX handling. These tests should mainly help avoid unnecessarily large memory allocations in case of malformed fonts. * src/truetype/ttgxvar.c (ft_var_readpackedpoints, ft_var_readpackeddeltas): Check number of points against stream size.

|
d353f6e0 | 2015-10-10 06:54:46 | * src/pcf/pcfread.c (pcf_read_TOC): Check stream size (#46162). | |
|
c12956e7 | 2015-10-09 09:38:32 | * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use real stream size. | |

|
6eb6158d | 2015-10-06 22:39:54 | [smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation. | |
|
066a4913 | 2015-10-06 07:55:32 | [cff] Return correct PS names from pure CFF (#46130). * src/cff/cffdrivr.c (cff_get_ps_name): Use SFNT service only for SFNT. | |

|
90e437e3 | 2015-10-01 20:00:27 | [sfnt] Make `tt_cmap4_char_map_linear' more robust (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Take care of border conditions (i.e., if the loop exits naturally). | |
|
fab67b85 | 2015-10-01 16:47:05 | * src/autofit/afranges.c (af_deva_nonbase_uniranges): Fix ranges. They should be a subset of `af_deva_uniranges'. | |

|
8bbcfb2c | 2015-09-30 23:08:53 | [smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove lightly used `last_ey'. (gray_start_cell, gray_render_line): Update. | |
|
dbd04269 | 2015-09-30 17:52:42 | [autofit] Replace `no-base' with `non-base'. * src/autofit/*: Do it. | |
|
2ff83a5c | 2015-09-30 14:44:29 | [sfnt] Rewrite `tt_cmap4_char_map_linear' (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Add code to better skip invalid segments. If searching the next character, provide a more efficient logic to speed up the code. | |
|
8651f37a | 2015-09-30 10:26:10 | [truetype] Adjust number of glyphs for malformed `loca' tables. * src/truetype/ttpload.c (tt_face_load_loca): Implement it. | |
|
52aad9df | 2015-09-29 12:38:11 | [raster] Minor style fix. | |
|
483007fc | 2015-09-29 11:22:15 | [pshinter] Avoid harmless overflow (#45984). * src/pshinter/pshglob.c (psh_blues_set_zones): Fix it. | |
|
a3046567 | 2015-09-28 09:45:56 | [autofit] Add support for Lao script. Thanks to Danh Hong <danhhong@gmail.com> for guidance with blue zone characters! * src/autofit/afblue.dat: Add blue zone data for Lao. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Lao standard characters. * src/autofit/afranges.c: Add Lao data. * src/autofit/afstyles.h: Add Lao data. | |

fb5268cf | 2015-09-28 02:01:43 | [base] Fix a leak by broken sfnt-PS or resource fork (#46028). open_face_from_buffer() frees passed buffer if valid font is not found. But if copying to the buffer is failed, the allocated buffer should be freed within the caller. * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free the buffer `sfnt_ps' if an error caused before calling open_face_from_buffer(). (Mac_Read_sfnt_Resource): Free the buffer `sfnt_data' if an error caused before calling open_face_from_buffer(); | |
|
8a05d250 | 2015-09-28 01:40:21 | [mac] Fix buffer size calculation for LWFN font. * src/base/ftmac.c (read_lwfn): Cast post_size to FT_ULong to prevent confused copy by too large chunk size. | |
|
d8a44ff9 | 2015-09-26 22:33:55 | Remove unused macro. | |
|
19188a9a | 2015-09-26 16:57:17 | [autofit] Minor tracing improvement. * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Don't emit blue zones header line if there are no blue zones. | |
|
41877539 | 2015-09-26 15:19:54 | [bzip2, gzip, lzw] Harmonize function signatures with prototype. Suggested by Hin-Tak Leung. * src/bzip2/ftbzip2.c (ft_bzip2_stream_io), src/gzip/ftgzip.c (ft_gzip_stream_io), src/lzw/ftlzw.c (ft_lzw_stream_io): Do it. | |
 |
265ade8e | 2015-09-26 14:51:30 | Add new FT_LOAD_COMPUTE_METRICS load flag. * include/freetype/freetype.h (FT_LOAD_COMPUTE_METRICS): New macro. * src/truetype/ttgload.c (compute_glyph_metrics): Usage. | |
|
d57f2271 | 2015-09-26 08:44:26 | * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add cast. | |
|
d7f456ee | 2015-09-26 08:37:14 | Formatting, minor comment corrections. | |
|
2439c515 | 2015-09-25 16:54:28 | [type1] Protect against invalid number of glyphs (#46029). * src/type1/t1load.c (parse_charstrings): Check number of `CharStrings' dictionary entries against size of data stream. | |
|
5339c75e | 2015-09-24 13:39:44 | [sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs. | |
|
c409eb18 | 2015-09-24 12:39:38 | [base, sfnt] Better checks for invalid cmaps (1/2). * src/base/ftobjs.c (FT_Get_Char_Index): Don't return out-of-bounds glyph indices. (FT_Get_First_Char): Updated. * src/sfnt/ttcmap.c (tt_cmap6_char_next): Don't return character codes greater than 0xFFFF. (tt_cmap8_char_index): Avoid integer overflow in computation of glyph index. (tt_cmap8_char_next): Avoid integer overflows in computation of both next character code and glyph index. (tt_cmap10_char_index): Fix unsigned integer logic. (tt_cmap10_char_next): Avoid integer overflow in computation of next character code. (tt_cmap12_next): Avoid integer overflows in computation of both next character code and glyph index. (tt_cmap12_char_map_binary): Ditto. (tt_cmap12_char_next): Simplify. (tt_cmap13_char_map_binary): Avoid integer overflow in computation of next character code. (tt_cmap13_char_next): Simplify. | |
