Either inexisting include/cache 125 (removed on 2006-03-20) is not needed to be listed explicitly. 126 Now ftmac.h is scanned only in the case of Mac OS & Mac OS X. 127 1282016-07-08 Alexei Podtelezhnikov <apodtele@gmail.com> 129 130 [smooth] Sub-banding protocol revision. 131 132 Rasterization sub-banding is utilized at large sizes while using a 133 rather small fixed memory pool. Indeed it is possible to make an 134 educated guess how much memory is necessary at a given size for a 135 given glyph. It turns out that, for a large majority of European 136 glyphs, you should store about 8 times more boundary pixels than 137 their height. Or, vice versa, if your memory pool can hold 800 138 pixels the band height should be 100 and you should sub-band 139 anything larger than that. Should you still run out of memory, 140 FreeType bisects the band but you have wasted some time. This is 141 what has been implemented in FreeType since the beginning. 142 143 It was overlooked, however, that the top band could grow to twice 144 the default band size leading to unnecessary memory overflows there. 145 This commit fixes that. Now the bands are distributed more evenly 146 and cannot exceed the default size. 147 148 Now the magic number 8 is really suitable for rather simple European 149 scripts. For complex Chinese logograms the magic number should be 150 13 but that is subject for another day. 151 152 * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding 153 protocol. 154 1552016-07-07 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> 156 157 [mac] Fix Savannah bug #48417. 158 159 Mac OS X linker throws errors when `-exported_symbol_list' input 160 file includes non-existing symbols. Reported by Ryan Schmidt. 161 162 * builds/exports.mk: Exclude ftmac.h from the headers for apinames 163 by default. Include it when ftmac.c would be compiled. 164 1652016-07-06 Werner Lemberg <wl@gnu.org> 166 167 * src/truetype/ttinterp.c (TInstruction_Function): Removed, unused. 168 1692016-07-05 Werner Lemberg <wl@gnu.org> 170 171 * Version 2.6.4 released. 172 ========================= 173 174 175 Tag sources with `VER-2-6-4'. 176 177 * docs/VERSION.TXT: Update documentation and bump version number to 178 2.6.4. 179 180 * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, 181 builds/windows/vc2005/index.html, 182 builds/windows/vc2008/freetype.vcproj, 183 builds/windows/vc2008/index.html, 184 builds/windows/vc2010/freetype.vcxproj, 185 builds/windows/vc2010/index.html, 186 builds/windows/visualc/freetype.dsp, 187 builds/windows/visualc/freetype.vcproj, 188 builds/windows/visualc/index.html, 189 builds/windows/visualce/freetype.dsp, 190 builds/windows/visualce/freetype.vcproj, 191 builds/windows/visualce/index.html, 192 builds/wince/vc2005-ce/freetype.vcproj, 193 builds/wince/vc2005-ce/index.html, 194 builds/wince/vc2008-ce/freetype.vcproj, 195 builds/wince/vc2008-ce/index.html: s/2.6.3/2.6.4/, s/263/264/. 196 197 * include/freetype/freetype.h (FREETYPE_PATCH): Set to 4. 198 199 * builds/unix/configure.raw (version_info): Set to 18:4:12. 200 * CMakeLists.txt (VERSION_PATCH): Set to 4. 201 202 * docs/CHANGES: Updated. 203 2042016-07-05 Werner Lemberg <wl@gnu.org> 205 206 * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Fix compiler warning. 207 2082016-07-04 Alexei Podtelezhnikov <apodtele@gmail.com> 209 210 [smooth] Variable type revision (part 2). 211 212 * src/smooth/ftgrays.c (TArea): Restore original definition as `int'. 213 (gray_render_line) [FT_LONG64]: Updated. 214 (gray_convert_glyph): 32-bit band bisection stack should be 32 bands. 215 (gray_convert_glyph_inner): Trace successes and failures. 216 2172016-07-04 Werner Lemberg <wl@gnu.org> 218 219 [autofit] Handle single-point contours as segments. 220 221 Doing so allows us to link them to edges – some fonts like 222 `NotoSansGurmukhi-Regular' have such isolated points sitting exactly 223 on other outlines. 224 225 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't 226 ignore one-point contours but handle them specially as one-point 227 segments. 228 (af_latin_hints_compute_edges): Append one-point segments to edges 229 if possible. 230 2312016-07-02 Werner Lemberg <wl@gnu.org> 232 233 [autofit] Remove unused structure members. 234 235 * src/autofit/afhints.h (AF_SegmentRec, AF_EdgeRec): Remove 236 `num_linked'. 237 238 * src/autofit/afcjk.c (af_cjk_hints_link_segments): Updated. 239 2402016-07-02 Werner Lemberg <wl@gnu.org> 241 242 [autofit] Update to Unicode 9.0.0. 243 244 * src/autofit/afranges.c (af_arab_nonbase_uniranges, 245 af_cyrl_uniranges): Add new data. 246 2472016-07-01 Alexei Podtelezhnikov <apodtele@gmail.com> 248 249 [smooth] Variable type revision (part 1). 250 251 This patch restores original `TCoord' definition as `int' so that the 252 rendering pool is used more efficiently on LP64 platforms (unix). 253 254 * src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some 255 fields to `TCoord'. 256 (gray_find_cell, gray_render_scanline, gray_render_line, gray_hline, 257 gray_sweep, gray_convert_glyph): Updated. 258 2592016-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> 260 261 [smooth] Minor clean-ups. 262 263 * src/smooth/ftgrays.c (gray_TWorker): Remove redundant `ycount'. 264 (gray_sweep, gray_convert_glyph, gray_dump_cells): Updated. 265 2662016-06-27 Alexei Podtelezhnikov <apodtele@gmail.com> 267 268 [smooth] Minor clean-ups. 269 270 * src/smooth/ftgrays.c (gray_convert_glyph): Do not use volatile 271 qualifier. 272 (gray_raster_render): Move span initializations from here. 273 (gray_sweep): ... to here and remove unused `target' argument. 274 2752016-06-26 Alexei Podtelezhnikov <apodtele@gmail.com> 276 277 [pcf] Fix handling of very large fonts (#47708). 278 279 * src/pcf/pcfread.c (pcf_get_encodings): Make `encodingOffset' an 280 unsigned short. 281 Only reject `0xFFFF' as an invalid encoding offset. 282 2832016-06-25 Werner Lemberg <wl@gnu.org> 284 285 [truetype] Really fix deallocation in case of error (#47726). 286 287 * src/truetype/ttgload.c (load_truetype_glyph): Thinko;

With this 375 change we change the files only if there are real modifications, so 376 we can avoid recompilations. 377 3782016-06-09 Werner Lemberg <wl@gnu.org> 379 380 [bdf] Check number of properties (#48166). 381 382 * src/bdf/bdflib.c (_bdf_parse_start): Implement. 383 3842016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com> 385 386 [smooth] Re-enable new line renderer on 64-bit archs. 387 388 * src/smooth/ftgrays.c (gray_render_line): Conditionally re-enable new 389 implementation, where it is safe from overflows. 390 3912016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com> 392 393 [smooth] Minor clean-ups. 394 395 * src/smooth/ftgrays.c (gray_dump_cells): Move out of the way. 396 (gray_render_span): Remove spurious casts and streamline. 397 3982016-06-07 Werner Lemberg <wl@gnu.org> 399 400 [autofit] Add support for Ethiopic script. 401 402 * src/autofit/afblue.dat: Add blue zone data for Ethiopic. 403 404 * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. 405 406 * src/autofit/afscript.h: Add Ethiopic standard characters. 407 408 * src/autofit/afranges.c: Add Ethiopic data. 409 410 * src/autofit/afstyles.h: Add Ethiopic data. 411 4122016-06-07 Werner Lemberg <wl@gnu.org> 413 414 [autofit] Fix compilation with VS2016 (#48126). 415 416 This compiler doesn't recognize the end-of-comment sequence `*/' if 417 it immediately follows non-ASCII characters. 418 419 * src/autofit/afscript.h: Ensure whitespace before `*/'. 420 4212016-06-04 Werner Lemberg <wl@gnu.org> 422 423 Fix a test for named instances (#48122). 424 425 This was missed while giving negative face indices an extended 426 meaning. 427 428 * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement. 429 4302016-05-31 Nikolaus Waxweiler <madigens@gmail.com> 431 432 [truetype] Let SHPIX move points in the twilight zone in v40. 433 434 * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in 435 the twilight zone. Otherwise, treat SHPIX the same as DELTAP. 436 Unbreaks various fonts such as older versions of Rokkitt and DTL 437 Argo T Light that would glitch severely after calling ALIGNRP after a 438 blocked SHPIX. 439 4402016-05-30 Werner Lemberg <wl@gnu.org> 441 442 [type42] Support `CharStrings' entry format as created by LilyPond. 443 444 * src/type42/t42parse.c (t42_parse_charstrings): Handle entries 445 having the format 446 447 (foo) cvn 12345 def 448 4492016-05-28 Werner Lemberg <wl@gnu.org> 450 451 * src/autofit/afranges.c: Remove `UL' postfix from hex numbers. 452 453 Suggested by Alexei. `UL' is only needed for 16bit compilers, but 454 it seems noone is using this anymore (and we no longer test whether 455 FreeType compiles in such an environment). Otherwise, it is easy to 456 add the postfix to the `AF_UNICODE_RANGE' macro. 457 4582016-05-26 Alexei Podtelezhnikov <apodtele@gmail.com> 459 460 [smooth] Shrink bisection stack. 461 462 The convergence of Bézier flatteners is fast with the deviation 463 from straight line being asymptotically cut 4-fold on each bisection. 464 This justifies smaller bisection stack size. 465 466 * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'. 467 (gray_render_conic): Create and use conic `bez_stack'. Move back the 468 band analysis from... 469 (gray_conic_to): ... here. 470 (gray_render_cubic): Create and use cubic `bez_stack'.

However, there is already a 789 proposal submitted to Unicode; see 790 791 https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf 792 793 Additionally, due to historical reasons, Unicode treats Khutsuri as 794 the same script as Mkhedruli, and so does OpenType. However, since 795 the two scripts have completely different shapes it can happen that 796 blue zones differ considerably. The tag `geok' used here (derived 797 from ISO 15924) to differentiate the two scripts is not an OpenType 798 tag in use. If we now have a font that contains both glyphs for 799 Mkhedruli and Khutsuri, and it uses OpenType features for both also, 800 HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence, 801 blue zones for `geok' are not used for glyphs involved in the 802 OpenType features. 803 804 An issue not yet resolved is which OpenType feature should be used 805 to access Mtavruli glyph shapes; right now, FreeType doesn't set up 806 support for them, but it is easy to add them later on as soon as 807 more information is available. 808 809 * src/autofit/afblue.dat: Add blue zone data for Georgian. 810 811 * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. 812 813 * src/autofit/afscript.h: Add Georgian standard characters. 814 815 * src/autofit/afranges.c: Add Georgian data. 816 817 * src/autofit/afstyles.h: Add Georgian data. 818 8192016-04-05 Werner Lemberg <wl@gnu.org> 820 821 [autofit] Provide dummy blue zone for pseudo script `none'. 822 823 Even if the dummy hinter is used as the handler for `none' (which 824 doesn't use blue zones), it is more consistent than the old value 825 (which was 0), pointing to Arabic... 826 827 * src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'. 828 * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. 829 830 * src/autofit/afstyles.h (none_dflt): Use AF_BLUE_STRINGSET_NONE. 831 8322016-03-30 Werner Lemberg <wl@gnu.org> 833 834 * src/pfr/pfrload.c (pfr_aux_name_load): Thinko (#47567). 835 8362016-03-30 Werner Lemberg <wl@gnu.org> 837 838 * src/pfr/pfrload.c (pfr_log_font_count): Better font size estimate. 839 8402016-03-30 Werner Lemberg <wl@gnu.org> 841 842 * src/pfr/pfrload.c (pfr_aux_name_load): Fix memory leak (#47567). 843 8442016-03-29 Werner Lemberg <wl@gnu.org> 845 846 * src/base/ftadvanc.c (FT_Get_Advances): Fix invalid left shift. 847 8482016-03-29 Werner Lemberg <wl@gnu.org> 849 850 [pfr] Fix binary search (#47514). 851 852 * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Handle border 853 conditions correctly. 854 8552016-03-29 Werner Lemberg <wl@gnu.org> 856 857 [pfr] Minor. 858 859 * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Replace `left', 860 `right', and `middle' with `min', `max', and `mid' as used in other 861 FreeType binary search code. 862 (pfr_load_bitmap_metrics): Fix invalid left shift. 863 8642016-03-29 Werner Lemberg <wl@gnu.org> 865 866 * src/pfr/pfrtypes.h: Replace all enums with macros. 867 868 We need `~FOO' to unset bits, and only with unsigned values (which 869 `enum' isn't normally) this works cleanly. 870 8712016-03-26 Werner Lemberg <wl@gnu.org> 872 873 [pfr] Robustify bitmap strike handling (#47514). 874 875 We did a binary search for a charcode without ensuring that the 876 searched data is ordered.

unhinted position of base 1050 point; use this to adjust the stem width depending on the PPEM so 1051 that it doesn't become too large under certain circumstances. 1052 Update all callers using value 0 for this argument except... 1053 (af_latin_align_linked_edge): Pass position delta of base point to 1054 `af_latin_compute_stem_width'. 1055 10562016-03-05 J Raynor <jxraynor@gmail.com> 1057 1058 Make FreeType compile on AIX out of the box. 1059 1060 * builds/unix/configure.raw (XX_ANSIFLAGS): Don't use `-ansi' on 1061 AIX. 1062 10632016-03-01 Werner Lemberg <wl@gnu.org> 1064 Kostya Serebryany

10942016-02-29 Werner Lemberg <wl@gnu.org> 1095 1096 [autofit] Add blue-zone support for Sinhala script. 1097 1098 This essentially moves the Sinhala script from the `Indic' hinter to 1099 the `Latin' hinter. 1100 1101 * src/autofit/afblue.dat: Add blue zone data for Sinhala. 1102 1103 * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. 1104 1105 * src/autofit/afscript.h: Add Sinhala

x-axis. 1117 1118 An example that gets better rendered is glyph `uusignTaml' (glyph 1119 index 2286) in font `FreeSerif.ttf' (Version 0412.2263) at 22ppem. 1120 1121 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly 1122 handle segments where the last point of the first segment is 1123 identical to the first point in the second one. This can happen for 1124 malformed fonts or spikes. We either merge the new segment with the 1125 previous one (both segments point into the same direction), or we 1126 discard the shorter segment if they point into different directions. 1127 11282016-02-27 Werner Lemberg <wl@gnu.org> 1129 1130 [autofit] Minor code clean-up. 1131 1132 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Change 1133 some local variable names to better differentiate between values 1134 along a segment and values orthogonal to it. 1135 11362016-02-26 Werner Lemberg <wl@gnu.org> 1137 1138 [autofit] Improve BOUND action. 1139 1140 In complex glyph shapes, the original logic was too simple to cater 1141 for situations that would actually need something similar to PS Hint 1142 masks. This fix should alleviate the worst cases. 1143 1144 * src/autofit/aflatin.c (af_latin_hint_edges): Don't allow 1145 complete disappearance of stems. 1146 11472016-02-25 Werner Lemberg <wl@gnu.org>

NULL bytes. 1229 1230 We need this to properly trace Multiple Master CFFs, which contain 1231 two SIDs that are charstrings. 1232 1233 This commit makes FreeType also show the last SID, omitted 1234 previously due to a bug. 1235 1236 * src/cff/cfftypes.h (CFF_FontRec): Add `string_pool_size' field. 1237 1238 * src/cff/cffload.c (cff_index_get_pointers): Add argument to return 1239 the pool size.

ttfautohint, commit 1498 071ae2c00e0d67f9d19418f4fade1c23d27dc185. 1499 1500 There were two bugs. 1501 1502 - We now use non-standard script tags like `khms' for special 1503 purposes. However, HarfBuzz maps such tags to `DFLT', and 1504 without this commit the associated lookups were incorrectly 1505 assigned to the non-standard tags. 1506 1507 - Let's assume we have a Bengali font, and the font's `DFLT' 1508 script tag handles the necessary lookups for Bengali, too. 1509 Without this commit, the `DFLT' lookups were assigned to 1510 ttfautohint's default script (usually `latn') before the 1511 standard lookups for Bengali were handled. 1512 1513 We now have the following order while searching for covered 1514 glyph indices. 1515 1516 special features of scripts (e.g. `sups' for Cyrillic) 1517 Unicode mappings of scripts 1518 remaining features of scripts (especially important for Indic 1519 scripts) 1520 default features of default script 1521 1522 * src/autofit/afshaper.c, src/autofit/afshaper.h 1523 (af_shaper_get_coverage): Add boolean parameter to indicate default 1524 script. 1525 Update all callers. 1526 1527 * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): 1528 Fix search order for coverages. 1529 15302016-01-19 Werner Lemberg <wl@gnu.org> 1531 1532 Various minor clang fixes. 1533 1534 * src/autofit/afcjk.c (af_cjk_metrics_init_widths), 1535 src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize 1536 `ch'. 1537 1538 * src/base/ftcalc.c (FT_MulFix) [FT_LONG64]: Add cast. 1539 1540 * src/base/ftdbgmem.c (ft_mem_table_destroy): Add cast. 1541 1542 * src/base/fthash.c (hash_num_lookup): Add cast. 1543 1544 * src/base/fttrigon.c (ft_trig_downscale) [FT_LONG64]: Fix cast. 1545 1546 * src/gxvalid/gxvcommn.c (gxv_EntryTable_validate): Comment out 1547 redundant code. 1548 1549 * src/type1/t1driver.c (t1_get_ps_font_value) <PS_DICT_SUBR>: Add 1550 cast. 1551 1552 * src/type1/t1load.c (parse_subrs): Fix type of `count'. 1553 15542016-01-19 Derek B.

This method provides a convenient way to 2386 extract it from writing-system-specific metrics structures, which 2387 all script definitions must implement. 2388 2389 * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New 2390 function type. 2391 (AF_WritingSystemClassRec): New member `style_metrics_getstdw'. 2392 (AF_DEFINE_WRITING_SYSTEM_CLASS): Updated. 2393 2394 * src/autofit/afcjk.c (af_cjk_get_standard_width): New function. 2395 (af_cjk_writing_system_class): Updated. 2396 * src/autofit/afdummy.c (af_dummy_writing_system_class): Updated. 2397 * src/autofit/afindic.c (af_cjk_get_standard_width): New function. 2398 (af_indic_writing_system_class): Updated. 2399 * src/autofit/aflatin.c (af_latin_get_standard_width): New function. 2400 (af_indic_writing_system_class): Updated. 2401 * src/autofit/aflatin.c (af_latin_get_standard_width): New function. 2402 (af_indic_writing_system_class): Updated. 2403 24042015-11-02 Nikolaus Waxweiler <madigens@gmail.com> 2405 2406 [autofit] Extend `AF_FaceGlobalsRec' to hold emboldening data. 2407 2408 * src/autofit/afglobal.h (AF_FaceGlobalsRec): Add fields. 2409 2410 * src/autofit/afglobal.c (af_face_globals_new): Initialize new 2411 fields. 2412 (af_face_globals_free): Reset new fields. 2413 24142015-11-02 Nikolaus Waxweiler <madigens@gmail.com> 2415 2416 [autofit] Add stem-darkening properties. 2417 2418 Actual code follows in a later commit. 2419 2420 * include/freetype/ftautoh.h: Document `no-stem-darkening' and 2421 `darkening-parameters'. 2422 2423 * src/autofit/afmodule.h: New fields `no_stem_darkening' and 2424 `darken_params'. 2425 2426 * src/autofit/afmodule.c (af_property_set, af_property_get): 2427 Handle them. 2428 (af_autofitter_init): Initialize them. 2429 24302015-11-02 Ben Wagner <bungeman@gmail.com> 2431 2432 [ftfuzzer] Add support for multiple files (patch #8779). 2433 2434 Currently, libFuzzer only supports mutation of a single file. We 2435 circumvent this problem by using an uncompressed tar archive as 2436 multiple-file input for the fuzzer. 2437 2438 This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing; 2439 a constructed tarball should contain a font file as the first 2440 element, and files to be attached as further elements. 2441 2442 * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers. 2443 (archive_read_entry_data, parse_data): New functions. 2444 (LLVMFuzzerTestOneInput): Updated. 2445 2446 * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom 2447 mutator for libFuzzer that can mutate tarballs in a sensible way. 2448 24492015-10-31 Werner Lemberg <wl@gnu.org> 2450 2451 [sfnt] Fix cmap 14 validation (#46346). 2452 2453 * src/sfnt/ttcmap.c (tt_cmap14_validate): Check limit

src/autofit/afhints.c (af_glyph_hints_dump_points): Minor. 2474 24752015-10-29 Werner Lemberg <wl@gnu.org> 2476 2477 * CMakeLists.txt: Remove code to set MSVC's /FD compiler switch. 2478 2479 Problem reported by David Capello <davidcapello@gmail.com>; see 2480 2481 https://lists.nongnu.org/archive/html/freetype-devel/2015-10/msg00108.html 2482 2483 for details. 2484 24852015-10-27 Werner Lemberg

(tt_face_load_loca): A thinko caused an 2508 incorrect adjustment of the number of glyphs, most often using far 2509 too large values. 2510 25112015-10-25 Werner Lemberg <wl@gnu.org> 2512 2513 [autofit] Improve tracing. 2514 2515 * src/autofit/afhints.c (af_print_idx, af_get_segment_index, 2516 af_get_edge_index): New functions. 2517 2518 (af_glyph_hints_dump_points): Remove unnecessary `|', `[', and `]'. 2519 Add segment and edge index for each point. 2520 Slightly change printing order of some elements. 2521 Don't print `-1' but `--' for missing elements. 2522 2523 (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Remove 2524 unnecessary `|', `[', and `]'. 2525 Don't print `-1' but `--' for missing elements. 2526 25272015-10-24 Werner Lemberg <wl@gnu.org> 2528 2529 [sfnt] Sanitize bitmap strike glyph height. 2530 2531 Problem reported by Nikolay Sivov <bunglehead@gmail.com>. 2532 2533 * src/sfnt/ttsbit.c (tt_face_load_strike_metrics):

I trust `ttx' (which has exactly such code) that it does 4254 the right thing here... 4255 4256 The reason that noone has ever noticed this bug is probably the fact 4257 that point-aligned subglyphs are rare, as are subglyphs with a 4258 number of points in the range [128;255], which is quite large (or 4259 even in the range [32768;65535], which is extremely unlikely). 4260 42612015-05-12 Chris Liddell <chris.liddell@artifex.com> 4262 4263 [cff] Make the `*curveto' operators more tolerant. 4264 4265 * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes 4266 `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate, 4267 pulling values off the stack until the stack is exhausted. 4268 Implicitly the stack must be a multiple (or for subtly different 4269 behaviour) a multiple plus a specific number of extra values deep. 4270 If that's not the case, enforce it (as the old code did). 4271 42722015-05-12 Chris Liddell <chris.liddell@artifex.com> 4273 4274 [cff] fix incremental interface with new cff code. 4275 4276 * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental 4277 interface to retrieve glyph data for a SEAC, it be left to the 4278 incremental interface callback to apply the encoding to raw 4279 character index (as it was in the previous code). 4280 42812015-04-29 Alexei Podtelezhnikov <apodtele@gmail.com> 4282 4283 [autofit] Speed up IUP. 4284 4285 * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to 4286 the same position from true interpolation, use `scale' to reduce 4287 divisions. 4288 42892015-04-28 Werner Lemberg <wl@gnu.org> 4290 4291 [cff] Use `name' table for PS name if we have a SFNT-CFF. 4292 4293 This follows the OpenType 1.7 specification.

[truetype] Fix regression in the incremental glyph loader. 5147 5148 * src/truetype/ttgload.c (load_truetype_glyph): For incremental 5149 fonts, the glyph index may be greater than the number of

show up with FreeType, exactly the same code 5157 leaks with ttfautohint's modified auto-hinter code (which gets used 5158 in a slightly different way). 5159 5160 It certainly doesn't harm since it is similar to already existing 5161 checks in the code for embedded arrays. 5162 5163 * src/autofit/afhints.c (af_glyph_hints_reload): Set `max_contours' 5164 and `max_points' for all cases. 5165

5197 51982015-01-18 Werner Lemberg <wl@gnu.org> 5199 5200 * src/base/ftobjs.c (FT_New_Library): Fix compiler warning. 5201 52022015-01-18 Chris Liddell <chris.liddell@artifex.com> 5203 5204 [raster] Fix Savannah bug #44022. 5205 5206 Add fallback for glyphs with degenerate bounding boxes. 5207 5208 If a glyph has only one very narrow feature, the bbox can end up 5209 with either the width or height of the bbox being 0, in which case 5210 no raster memory is allocated and no attempt is made to render the 5211 glyph. This is less than ideal when the drop-out compensation in 5212 the rendering code would actually result in the glyph being 5213 rendered. 5214 5215 This problem can be observed with the `I' glyph (gid 47) in the 5216 Autodesk RomanS TrueType font. 5217 5218 * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either 5219 dimension is zero to explicitly round up/down (instead of simply 5220 round). 5221 52222015-01-17 Werner Lemberg <wl@gnu.org> 5223 5224 Add some tools to handle yearly copyright notice updates. 5225 5226 We are now following the GNU guidelines: A new release automatically 5227 means that the copyright year of all affected files gets updated; it 5228 is no longer used to track years of modification changes. 5229 5230 * src/tools/update-copyright-year: New Perl script. 5231 * src/tools/update-copyright: New shell script that calls 5232 `update-copyright-year' on all files. 5233 * src/tools/no-copyright: Exceptions that should not be handled by 5234 `update-copyright' 5235 52362015-01-14 Werner Lemberg <wl@gnu.org> 5237 5238 * docs/CHANGES: Updated, using a description from Behdad. 5239 52402015-01-14 Behdad Esfahbod <behdad@behdad.org> 5241 5242 * src/autofit/afmodule.c (af_autofitter_done): Fix compiler warning. 5243 52442015-01-14 Behdad Esfahbod <behdad@behdad.org> 5245 5246 [autofit] Add embedded array of segments and edges. 5247 5248 Avoids multiple mallocs per typical glyphs. 5249 5250 With this and recent changes to avoid mallocs, the thread-safe 5251 stack-based loader is now as fast as the previous model that had one 5252 cached singleton. 5253 5254 * src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED): 5255 New macros. 5256 (AF_AxisHintsRec): Add two arrays for segments and edges. 5257 5258 * src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate 5259 data if number of segments exceeds given threshold value. 5260 (af_axis_hints_new_edge): Only allocate data if number of edges 5261 exceeds given threshold value. 5262 (af_glyph_hints_done): Updated. 5263 52642015-01-14 Behdad Esfahbod <behdad@behdad.org> 5265 5266 [autofit] Add embedded arrays for points and contours. 5267 5268 This avoids at least two malloc calls for typical glyphs. 5269 5270 * src/autofit/afhints.h (AF_POINTS_EMBEDDED, AF_CONTOURS_EMBEDDED): 5271 New macros. 5272 (AF_GlyphHintsRec): Add two arrays for contours and points. 5273 5274 * src/autofit/afhints.c (af_glyph_hints_init, af_glyph_hints_done): 5275 Updated. 5276 (af_glyph_hints_reload): Only allocate data if number of contours or 5277 points exceeds given threshold values. 5278 52792015-01-14 Behdad Esfahbod <behdad@behdad.org> 5280 5281 [autofit] Allocate hints object on the stack. 5282 5283 This avoids one malloc per load. 5284 5285 * src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to 5286 `AF_GlyphHints'. 5287 Update prototype. 5288 5289 * src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints' 5290 parameter instead of `FT_Memory'. 5291 (af_loader_done): Directly reset `load_hints'. 5292 (af_loader_load_g): Updated. 5293 5294 * src/autofit/afmodule.c (af_autofitter_load_glyph): Use local 5295 `hints' object. 5296 52972015-01-14 Behdad Esfahbod <behdad@behdad.org> 5298 5299 [autofit] Reuse slot glyph loader. 5300 5301 No need to create a new glyph loader; we can reuse the one from 5302 `slot->internal->loader'. It's hard to tell why it was written that 5303 way originally, but new code looks sound and correct to me, and 5304 avoids lots of allocations. 5305 5306 * src/autofit/afloader.c (af_loader_init): Change return type to 5307 `void'. 5308 Don't call `FT_GlyphLoader_New'. 5309 (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'. 5310 (af_loader_load_g): Update code to use `internal->loader', which 5311 doesn't need copying of data. 5312 5313 * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member. 5314 Update prototype. 5315 5316 * src/autofit/afmodule.c (af_autofitter_load_glyph): Updated. 5317 53182015-01-14 Behdad Esfahbod <behdad@behdad.org> 5319 5320 [autofit] Remove (unused) support for composite glyphs. 5321 5322 We never have to deal with composite glyphs in the autohinter, as 5323 those will be loaded into FORMAT_OUTLINE by the recursed 5324 `FT_Load_Glyph' function. 5325 5326 In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply 5327 FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies 5328 FT_LOAD_NO_HINTING: 5329 5330 /* resolve load flags dependencies */ 5331 5332 if ( load_flags & FT_LOAD_NO_RECURSE ) 5333 load_flags |= FT_LOAD_NO_SCALE | 5334 FT_LOAD_IGNORE_TRANSFORM; 5335 5336 if ( load_flags & FT_LOAD_NO_SCALE ) 5337 { 5338 load_flags |= FT_LOAD_NO_HINTING | 5339 FT_LOAD_NO_BITMAP; 5340 5341 load_flags &= ~FT_LOAD_RENDER; 5342 } 5343 5344 and as such the auto-hinter is never called. Thus, the recursion in 5345 `af_loader_load_g' never actually happens. So remove the depth 5346 counter as well. 5347 5348 * src/autofit/afloader.c (af_loader_load_g): Remove `depth' 5349 parameter. 5350 <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code. 5351 (af_loader_load_glyph): Updated. 5352 53532015-01-14 Behdad Esfahbod <behdad@behdad.org> 5354 5355 [raster] Fix uninitialized memory access. 5356 5357 Apparently `ras.cProfile' might be uninitialized. This will be the 5358 case if `ras.top == ras.cProfile->offset', as can be seen in 5359 `End_Profile'. The overshoot code introduced in a change `Fix B/W 5360 rasterization of subglyphs with different drop-out modes.' (from 5361 2009-06-18) violated this, accessing `ras.cProfile->flags' 5362 unconditionally just before calling `End_Profile' (which then 5363 detected that `cProfile' is uninitialized and didn't touch it). 5364 5365 This was harmless, and was not detected by valgrind before because 5366 the objects were allocated on the `raster_pool', which was always 5367 initialized. With recent change to allocate raster buffers on the 5368 stack, valgrind now reported this invalid access. 5369 5370 * src/raster/ftraster.c (Convert_Glyph): Don't access an 5371 uninitialized `cProfile'. 5372 53732015-01-14 Behdad Esfahbod <behdad@behdad.org> 5374 5375 [smooth] Fix uninitialized memory access. 5376 5377 Looks like `ras.span_y' could always be used without initialization. 5378 This was never detected by valgrind before because the library-wide 5379 `raster_pool' was used for the worker object and `raster_pool' was 5380 originally zero'ed. But subsequent reuses of it were using `span_y' 5381 uninitialized. With the recent change to not use `render_pool' and 5382 allocate worker and buffer on the stack, valgrind now detects this 5383 uninitialized access. 5384 5385 * src/smooth/ftgrays.c (gray_raster_render): Initialize 5386 `ras.span_y'. 5387 53882015-01-14 Behdad Esfahbod <behdad@behdad.org> 5389 5390 [base] Don't initialize unused `driver->glyph_loader'. 5391 5392 * src/base/ftobjs.c (Destroy_Driver): Don't call 5393 `FT_GlyphLoader_Done'. 5394 (FT_Add_Module): Don't call `FT_GlyphLoader_New'. 5395 53962015-01-14 Behdad Esfahbod <behdad@behdad.org> 5397 5398 [base] Don't allocate `library->raster_pool' anymore. 5399 5400 It's unused after the following commits: 5401 5402 [raster] Allocate render pool for mono rasterizer on the stack. 5403 [raster] Remove 5-level gray AA mode from monochrome rasterizer. 5404 5405 The value of FT_RENDER_POOL_SIZE still serves the purpose it used to 5406 serve, which is, to adjust the pool size. But the pool is now 5407 allocated on the stack on demand. 5408 5409 * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement. 5410 54112015-01-14 Behdad Esfahbod <behdad@behdad.org> 5412 5413 [base] Do not reorder library->renderers upon use. 5414 5415 Instead of keeping `library->renderers' in a MRU order, just leave 5416 it as-is. The MRU machinery wasn't thread-safe. 5417 5418 With this patch, rasterizing glyphs from different faces from 5419 different threads doesn't fail choosing rasterizer 5420 (FT_Err_Cannot_Render_Glyph). 5421 5422 Easiest to see that crash was to add a `printf' (or otherwise let 5423 thread yield in FT_Throw with debugging enabled). 5424 5425 * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c 5426 (FT_Outline_Render): Don't call `FT_Set_Renderer'. 5427 54282015-01-14 Behdad Esfahbod <behdad@behdad.org> 5429 5430 [raster] Allocate render pool for mono rasterizer on the stack. 5431 5432 Instead of using the `render_pool' member of `FT_Library' that is 5433 provided down to the rasterizer, completely ignore that and allocate 5434 needed objects on the stack instead. 5435 5436 With this patch, rasterizing glyphs from different faces from 5437 different threads doesn't crash in the monochrome rasterizer. 5438 5439 * src/raster/ftraster.c (black_TRaster): Remove `buffer', 5440 `buffer_size', and `worker' members. 5441 5442 (ft_black_render): Create `buffer' locally. 5443 (ft_black_reset): Updated. 5444 54452015-01-14 Behdad Esfahbod <behdad@behdad.org> 5446 5447 [raster] Remove 5-level gray AA mode from monochrome rasterizer. 5448 5449 It was off by default and couldn't be turned on at runtime.

As such, the code was always 5500 using the singleton `TT_ExecContext' that was stored in `TT_Driver'. 5501 This was, clearly, not threadsafe. 5502 5503 With this patch, loading glyphs from different faces from different 5504 threads doesn't crash in the bytecode loader code. 5505 5506 * src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member. 5507 (TT_DriverRec): Remove `context' member. 5508 5509 * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove 5510 `TT_ExecContext' code related to a global `TT_Driver' object. 5511 5512 (tt_driver_done): Don't remove `TT_ExecContext' object here but ... 5513 (tt_size_done_bytecode): ... here. 5514 5515 (tt_driver_init): Don't create `TT_ExecContext' object here but ... 5516 (tt_size_init_bytecode): ... here, only on demand. 5517 5518 * src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug 5519 code. 5520 (TT_New_Context): Remove `TT_ExecContext' code related to a global 5521 `TT_Driver' object. 5522 5523 * src/truetype/ttinterp.h: Updated. 5524 5525 * src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated. 5526 55272015-01-14 Behdad Esfahbod <behdad@behdad.org> 5528 5529 [autofit] Allocate AF_Loader on the stack instead of AF_Module. 5530 5531 Stop sharing a global `AF_Loader'. Allocate one on the stack during 5532 glyph load. 5533 5534 Right now this results in about 25% slowdown, to be fixed in a 5535 following commit. 5536 5537 With this patch loading glyphs from different faces from different 5538 threads doesn't immediately crash in the autohinting loader code. 5539 5540 Bugs: 5541 5542 https://bugzilla.redhat.com/show_bug.cgi?id=1164941 5543 5544 * src/autofit/afloader.c (af_loader_init): Pass 5545 `AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments. 5546 (af_loader_reset, af_loader_load_glyph): Also pass `loader' as 5547 argument. 5548 (af_loader_done): Use `AF_Loader' instead of `AF_Module' as 5549 argument. 5550 5551 * src/autofit/afmodule.c (af_autofitter_init): Don't call 5552 `af_loader_init'. 5553 (af_autofitter_done): Don't call `af_loader_done'. 5554 (af_autofitter_load_glyph): Use a local `AF_Loader' object. 5555 5556 * src/autofit/afloader.h: Include `afmodule.h'. 5557 Update prototypes. 5558 Move typedef for `AF_Module' to... 5559 5560 * src/autofit/afmodule.h: ... this place. 5561 No longer include `afloader.h'. 5562 55632015-01-14 Behdad Esfahbod <behdad@behdad.org> 5564 5565 * src/type42/t42objs.h (T42_DriverRec): Remove unused member. 5566 55672015-01-12 Werner Lemberg <wl@gnu.org> 5568 5569 Fix Savannah bug #43976. 5570 5571 Assure that FreeType's internal include directories are found before 5572 `CPPFLAGS' (which might be set by the user in the environment), and 5573 `CPPFLAGS' before `CFLAGS'. 5574 5575 * builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'. 5576 (FT_COMPILE): Make this a special variable for compiling only the 5577 files handled in `freetype.mk'. 5578 (.c.$O): Removed, unused. 5579 5580 * src/*/rules.mk (*_COMPILE): Fix order of include directories. 5581 55822015-01-11 Werner Lemberg <wl@gnu.org> 5583 5584 [truetype] Prettifying. 5585 5586 * src/truetype/ttinterp.c (project, dualproj, fast_project, 5587 fast_dualproj): Rename to... 5588 (PROJECT, DUALPROJ, FAST_PROJECT, FAST_DUALPROJ): ... this. 5589 55902015-01-11 Werner Lemberg <wl@gnu.org> 5591 5592 * src/truetype/ttinterp.c (Ins_JROT, Ins_JROF): Simplify. 5593 5594 Based on a patch from Behdad. 5595 55962015-01-11 Werner Lemberg <wl@gnu.org> 5597 5598 * src/truetype/ttinterp.c (Ins_SxVTL): Simplify function call. 5599 56002015-01-11 Werner Lemberg <wl@gnu.org> 5601 5602 * src/truetype/ttinterp.c (Normalize): Remove unused argument. 5603 56042015-01-11 Werner Lemberg <wl@gnu.org> 5605 5606 [truetype] More macro expansions. 5607 5608 * src/truetype/ttinterp.c

expansions. 5622 5623 Based on a patch from Behdad. 5624 5625 * src/truetype/ttinterp.c (DO_*): Expand macros into corresponding 5626 `Ins_*' functions. 5627 (TT_RunIns): Replace `DO_*' macros with `Ins_*' function calls. 5628 (ARRAY_BOUND_ERROR): Remove second definition, which is no longer 5629 needed. 5630 (Ins_SVTCA, Ins_SPVTCA, Ins_SFVTCA): Replaced with... 5631 (Ins_SxyTCA): New function. 5632 56332015-01-10 Werner Lemberg <wl@gnu.org> 5634 5635 [truetype] Remove TT_CONFIG_OPTION_INTERPRETER_SWITCH. 5636 5637 Behdad suggested this code simplification, and nobody objected... 5638 5639 * include/config/ftoption.h, devel/ftoption.h 5640 (TT_CONFIG_OPTION_INTERPRETER_SWITCH): Remove. 5641 5642 * src/truetype/ttinterp.c [TT_CONFIG_OPTION_INTERPRETER_SWITCH]: 5643 Remove related code.
