12017-09-16 Werner Lemberg <wl@gnu.org> 2 3 * Version 2.8.1 released. 4 ========================= 5 6 7 Tag sources with `VER-2-8-1'. 8 9 * docs/VERSION.TXT: Add entry for version 2.8.1. 10 * docs/CHANGES: Updated. 11 12 * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, 13 builds/windows/vc2005/index.html, 14 builds/windows/vc2008/freetype.vcproj, 15 builds/windows/vc2008/index.html, 16 builds/windows/vc2010/freetype.vcxproj, 17 builds/windows/vc2010/index.html, 18 builds/windows/visualc/freetype.dsp, 19 builds/windows/visualc/freetype.vcproj, 20 builds/windows/visualc/index.html, 21 builds/windows/visualce/freetype.dsp, 22 builds/windows/visualce/freetype.vcproj, 23 builds/windows/visualce/index.html, 24 builds/wince/vc2005-ce/freetype.vcproj, 25 builds/wince/vc2005-ce/index.html, 26 builds/wince/vc2008-ce/freetype.vcproj, 27 builds/wince/vc2008-ce/index.html: s/2.8/2.8.1/, s/28/281/. 28 29 * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. 30 31 * builds/unix/configure.raw (version_info): Set to 21:0:15. 32 * CMakeLists.txt (VERSION_PATCH): Set to 1. 33 342017-09-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> 35 36 [sfnt] lowest gcc for vectors (e1d0249e) is changed to 4.7. 37 38 __builtin_shuffle() was introduced in gcc-4.7. The lowest 39 gcc to enable vector operation is delayed from 4.6 to 4.7. 40 41 * src/sfnt/pngshim.c (premultiply_data): Fix cpp-macro to 42 enable the vector operation, to change the lowest gcc version 43 from 4.6 to 4.7. 44 452017-09-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> 46 47 [cache] Fix a possible overflow by signed integer comparison. 48 49 Improve the code by 5d3ff05615dda6d1325ed612381a17a0df04c975 , 50 issues are found by Behdad Esfahbod and Werner Lemberg. 51 52 * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Replace 53 a subtraction to check higher bit by a bit operation, 54 and cpp-conditionalize for appropriate systems. Add better 55 documentation to the comment. 56 (FTC_ImageCache_LookupScaler): Ditto. 57 (FTC_SBitCache_Lookup): Ditto. 58 (FTC_SBitCache_LookupScaler): Ditto. 59 602017-09-13 Werner Lemberg <wl@gnu.org> 61 62 [autofit] Really fix #41334 (#52000). 63 64 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Set 65 `segment->delta' everywhere. 66 672017-09-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> 68 69 [autofit, sfnt] Fix for `make multi'. 70 71 * src/autofit/afshaper.c: Include FT_ADVANCE_H, to use 72 FT_Get_Advance() in it. 73 * src/sfnt/ttcmap.c: Include FT_SERVICE_POSTSCRIPT_CMAPS_H 74 to use PS_Unicodes in it, also include `ttpost.h' to use 75 tt_face_get_ps_name() in it. 76 772017-09-11 Azzuro <azzuro@team-mediaportal.com> 78 79 [build] Improve builds with different MS Visual Studio versions. 80 81 * builds/windows/vc2010/freetype.vcxproj: Switch platform toolset 82 according to the Visual Studio version. 83 842017-09-11 Werner Lemberg <wl@gnu.org> 85 86 * src/sfnt/ttkern.c (tt_face_load_kern): Reject format 2 tables. 87 88 Reported by Behdad. 89 902017-09-09 Werner Lemberg <wl@gnu.org> 91 92 [autofit] Improve communication with ftgrid. 93 94 * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): 95 Provide values in font units. 96 972017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> 98 99 [base] Remove a check for resource ID in the resource fork driver. 100 101 LastResort.dfont has a marginal resource ID 0xFFFF for sfnt 102 resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' 103 (1-46), tells that some IDs are reserved and should not be used. 104 FreeType2 just uses resource ID to sort the fragmented resource. 105 To accept the marginal fonts, the checking is removed. 106 107 * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id 108 validity check, fix a trace message format. 109 1102017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> 111 112 [sfnt, truetype] Register the tags for marginal fonts. 113 114 The first 32bit of standard TrueType variants is 0x00010000, 115 `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac 116 OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources 117 starting 0xA5 followed by `kbd' or `lst'. Considering the following 118 data could be parsed as conventional TrueType fonts, the header 119 checking is updated to allow these tags. It seems that recent Mac 120 OS X has already switched to normal TTF for these fonts. 121 122 See the discussion at 123 http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 124 125 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header 126 tags for Keyboard.dfont and LastResort.dfont. 127 * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource 128 starts with TTAG_0xA5kbd or TTAG_0xA5lst. 129 * src/truetype/ttobjs.c (tt_face_init): Accept the face with the 130 format tag is TTAG_0xA5kbd or TTAG_0xA5lst. 131 1322017-09-05 Werner Lemberg <wl@gnu.org> 133 134 Fix multiple calls of `FT_Bitmap_Convert'. 135 136 The documentation of `FT_Bitmap_Convert' says that multiple calls do 137 proper reallocation of the target FT_Bitmap object. However, this 138 failed for the sequence 139 140 non-empty bitmap 141 empty bitmap 142 non-empty bitmap 143 144 Reason was that `FT_Bitmap_Convert' only reallocated the bitmap 145 buffer if it became too small; it didn't make the buffer smaller. 146 For an empty bitmap following a non-empty one, only the buffer 147 dimension got set to zero, without deallocation. If the next call 148 was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was 149 triggered. 150 151 * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target 152 buffer to the correct size. 153 154 * docs/CHANGES: Document it. 155 1562017-09-05 Werner Lemberg <wl@gnu.org> 157 158 [bdf] Fix size and resolution handling. 159 160 * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if 161 `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are 162 missing. 163 164 * docs/CHANGES: Document it. 165 1662017-08-25 Alexei Podtelezhnikov <apodtele@gmail.com> 167 168 Swap `ALLOC_MULT' arguments (#51833). 169 170 * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated. 171 * src/winfonts/winfnt.c (FNT_Load_Glyph): Updated. 172 * src/raster/ftrend1.c (ft_raster1_render): Updated. 173 1742017-08-23 Werner Lemberg <wl@gnu.org> 175 176 [sfnt] Fix clang compilation (#51788). 177 178 * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of 179 scalars. 180 (vector_shuffle): New macro to take care of a different built-in 181 function name on clang. 182 1832017-08-22 Werner Lemberg <wl@gnu.org> 184 185 [base] Don't zero out allocated memory twice (#51816). 186 187 Patch applied from bug report. 188 189 * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to 190 avoid unnecessary overhead. 191 1922017-08-22 Werner Lemberg <wl@gnu.org> 193 194 [truetype] Integer overflow. 195 196 Changes triggered by 197 198 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107 199 200 * src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use 201 NEG_LONG. 202 2032017-08-17 Alexei Podtelezhnikov <apodtele@gmail.com> 204 205 [sfnt] Avoid synthetic unicode for symbol fonts with PUA. 206 207 Reported as 208 209 https://bugs.chromium.org/p/chromium/issues/detail?id=754574 210 211 * src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL. 212 2132017-08-16 Werner Lemberg <wl@gnu.org> 214 215 * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings. 216 2172017-08-15 Behdad Esfahbod <behdad@behdad.org> 218 219 [sfnt] Speed up PNG image loading. 220 221 This reduces the overhead of `premultiply_data' by 60%. 222 223 * src/sfnt/pngshim.c (premultiply_data): Provide code which uses 224 gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a 225 time. 226 2272017-08-11 Werner Lemberg <wl@gnu.org> 228 229 [sfnt, truetype] Improve handling of missing sbits. 230 231 Requested by Behdad. 232 233 Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain 234 entries in the bitmap strike(s) for empty glyphs. Instead, they 235 rely that a space glyph gets created from the font's metrics data. 236 This commit makes FreeType behave accordingly. 237 238 * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error 239 code. 240 241 * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes 242 to make a distinction between a missing bitmap in a composite and a 243 simple missing bitmap. 244 245 * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a 246 bitmap-only font), synthesize an empty bitmap glyph if metrics are 247 available. 248 2492017-08-10 Werner Lemberg <wl@gnu.org> 250 251 [base] Minor API improvement for default variation axis setting. 252 253 * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, 254 FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, 255 FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0. 256 257 * docs/CHANGES: Updated. 258 2592017-08-08 Werner Lemberg <wl@gnu.org> 260 261 [psnames] Really fix issue #49949. 262 263 We now use a separate preprocessor macro to handle both definition 264 and declaration of the glyph name arrays. 265 266 * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. 267 268 * src/tools/glnames.py (StringTable::dump, 269 StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. 270 (dump_encoding): Ditto. 271 (main): Use `wb' mode for writing the output file, which works on 272 Windows also. 273 274 * src/psnames/pstables.h: Regenerated. 275 2762017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> 277 278 [smooth] Harmony LCD rendering. 279 280 This is a new technology for LCD-optimized rendering. It capitalizes 281 on the fact that each color channel grid is shifted by a third of a 282 pixel. Therefore it is logical to render 3 separate monochrome 283 bitmaps shifting the outline by 1/3 pixel, and then combine them. 284 Importantly, the resulting output does not require additional LCD 285 filtering. 286 287 * src/smooth/ftsmooth.c (ft_smooth_render_generic) 288 [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized 289 rendering. 290 291 * include/freetype/ftlcdfil.h, include/freetype/freetype.h, 292 include/freetype/config/ftoption.h, devel/ftoption.h: Updated 293 documentation. 294 2952017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> 296 297 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up. 298 2992017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> 300 301 * src/sfnt/ttpost.c (format): Use otspec-compliant versions. 302 3032017-08-05 Werner Lemberg <wl@gnu.org> 304 305 [truetype] Integer overflow. 306 307 Reported as 308 309 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2868 310 311 * src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG. 312 3132017-08-05 Werner Lemberg <wl@gnu.org> 314 315 [base, truetype] New function `FT_Get_Var_Axis_Flags'. 316 317 The reserved `flags' field got a value in OpenType version 1.8.2; 318 unfortunately, the public `FT_Var_Axis' structure misses the 319 corresponding element. Since we can't add a new field, we add an 320 access function. 321 322 * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function. 323 324 * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro. 325 Updated. 326 327 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory 328 of `mmvar' to hold axis flags. 329 Fill the axis flags array. 330 331 * docs/CHANGES: Updated. 332 3332017-08-03 Nikolaus Waxweiler <madigens@gmail.com> 334 335 [truetype] Fix metrics of B/W hinting in v40 mode. 336 337 Phantom points are now saved outside v40 backwards compatibility 338 mode. This fixes the jumping glyphs when switching between v35 and 339 v40 monochrome mode. 340 341 * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic. 342 3432017-08-03 Nikolaus Waxweiler <madigens@gmail.com> 344 345 [truetype] Do not set any ClearType flags in v40 monochrome mode. 346 347 This fixes weird behavior of instructions that resulted in rendering 348 differences between v35 and v40 in monochrome mode, e.g., in 349 `timesbi.ttf'. 350 351 * src/truetype/ttinterp.c (Ins_GETINFO) 352 [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check 353 `subpixel_hinting_lean'. 354 3552017-08-01

363 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position 364 while loading the `avar' table. 365 3662017-08-01 Werner Lemberg <wl@gnu.org> 367 368 [sfnt, truetype] Minor adjustments for OpenType 1.8.2. 369 370 * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now 371 (tighter) limits. 372 373 * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType 374 version explicitly allows all negative values for the number of 375 contours if we have a composite glyph (this is for better backwards 376 compatibility I guess), but it still recommends value -1. 377 3782017-07-26 Werner Lemberg <wl@gnu.org> 379 380 [cff] Integer overflow. 381 382 Reported as 383 384 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2738 385 386 * src/cff/cf2hints.c

overflow run-time errors (#46149, #48979). 957 958 This commit (mainly for 32bit CPUs) is the first of a series of 959 similar commits to handle known integer overflows. Basically, all 960 of them are harmless, since they affect rendering of glyphs only, 961 not posing security threats. It is expected that fuzzying will show 962 up more overflows, to be fixed in due course. 963 964 The idea is to mark places where overflows can occur, using macros 965 that simply cast to unsigned integers, because overflow arithmetic 966 is well defined in this case. Doing so suppresses run-time errors 967 of sanitizers without adding computational overhead. 968 969 * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, 970 OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, 971 OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. 972 973 * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, 974 FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, 975 ft_corner_orientation): Use new macros. 976 977 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. 978 9792017-05-28 Werner Lemberg <wl@gnu.org> 980 981 * include/freetype/internal/ftcalc.h (FLOAT_TO_FIXED): Remove. 982 983 This macro is not used. 984 9852017-05-28 Werner Lemberg <wl@gnu.org> 986 987 [cff] s/cf2_floatToFixed/cf2_doubleToFixed/. 988 989 The new name better describes what the macro actually does; 990 additionally, we don't need a trailing `f' for literals (there was 991 only a single such instance in the code, but this caused a clang 992 warning because the macro itself uses `double' literals). 993 994 * src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h, 995 src/cff/cf2font.c, src/cff/cf2hints.c: Updated. 996 9972017-05-28 Werner Lemberg <wl@gnu.org> 998 999 Fix negation of INT_MIN and LONG_MIN (#46149). 1000 1001 * src/base/ftcalc.c (FT_MOVE_SIGN): Add argument to pass unsigned 1002 value, to be used as the result. 1003 (FT_MulDiv, FT_MulDiv_No_Round, FT_DivFix, FT_MulFix, 1004 FT_Vector_NormLen): Updated. 1005 10062017-05-27 Werner Lemberg <wl@gnu.org> 1007 1008 [truetype] Fix handling of design coordinates (#51127). 1009 1010 * src/truetype/ttgxvar.c (tt_set_mm_blend): Compute all design 1011 coordinates if we have to create the `blends->coord' array. 1012 (TT_Get_MM_Blend, TT_Get_Var_Design): Select default instance 1013 coordinates if no instance is selected yet. 1014 10152017-05-24 Werner Lemberg <wl@gnu.org> 1016 1017 [bdf, pcf] Support ISO646.1991-IRV character encoding (aka ASCII). 1018 1019 Problem reported by Marek Kašík <mkasik@redhat.com>, cf. 1020 1021 https://bugzilla.redhat.com/show_bug.cgi?id=1451795 1022 1023 * src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdrivr.c 1024 (PCF_Face_Init): Implement it. 1025 10262017-05-20 Nikolaus Waxweiler <madigens@gmail.com> 1027 1028 [truetype] Always use interpreter v35 for B/W rendering (#51051). 1029 1030 * src/truetype/ttgload.c (tt_loader_init) 1031 [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Adjust 1032 `subpixel_hinting_lean', `grayscale_cleartype', and 1033 `vertical_lcd_lean' accordingly. 1034 1035 * src/truetype/ttinterp.c (Ins_GETINFO): Updated. 1036 (TT_RunIns): Update `backward_compatibility' flag. 1037 10382017-05-20 Alexei Podtelezhnikov <apodtele@gmail.com> 1039 1040 [smooth] Implement minimal dynamic padding for LCD filtering. 1041 1042 Extra bitmap padding for LCD filtering depends on the filter.

To be more precise, 1463 the behaviour is restored for TrueType fonts only; for other font 1464 formats like Type 1, this is a new feature of the `light' hinting 1465 mode. 1466 1467 *

Updated. 1476 1477 * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use 1478 `autohint_metrics'. 1479 (af_loader_load_glyph): s/internal/slot_internal/. 1480 Initialize `autohint_metrics'

2415 [autofit] Prevent overlapping blue zones. 2416 2417 Problem reported as 2418 2419 https://github.com/google/fonts/issues/632 2420 2421 The font in question (Nunito) has values 705 and 713 for the 2422 reference and overshoot values, respectively, of the first blue 2423 zone. Blue zone 2, however, has value 710 for both the reference 2424 and overshoot. At 12ppem, reference and overshoot of blue zone 0 2425 becomes 8px, while blue zone 2 becomes 9px. 2426 2427 A peculiarity of this font is that the tops of isolated vertical 2428 stems like `N' have a slight overshoot also. The auto-hinter tries 2429 to find the nearest blue zone using the *original* coordinates. For 2430 vertical stems, this is value 713. For normal horizontal tops like 2431 in character `E', this is value 710. Since value 713 is mapped to 2432 8px but value 710 to 9px, `N' and similar characters are one pixel 2433 higher than `E', which looks very bad. 2434 2435 This commit sanitizes blue zones to avoid such a behaviour. 2436 2437 * src/autofit/aflatin.c (af_latin_sort_blue): New function. 2438 (af_latin_metrics_init_blues): Sort blue values and remove overlaps. 2439 24402017-02-12 Alexei Podtelezhnikov <apodtele@gmail.com> 2441 2442 * src/smooth/ftgrays.c (gray_sweep): Improve code. 2443 24442017-02-06 Werner Lemberg <wl@gnu.org> 2445 2446 [truetype] Implement `VVAR' table support. 2447 2448 * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to... 2449 (GX_HVVarTable): ...This. 2450 (GX_Blend): Add fields for `VVAR' table handling. 2451 Other minor updates. 2452 2453 * src/truetype/ttgxvar.c (ft_var_load_hvar): Renamed to... 2454 (ft_var_load_hvvar): ...This. 2455 Handle VVAR loading also (controlled by an additional parameter). 2456 (tt_hadvance_adjust): Renamed to... 2457 (tt_hvadvance_adjust): ...This. 2458 Handle application of advance height also (controlled by an 2459 additional parameter). 2460 (tt_hadvance_adjust, tt_vadvance_adjust): Wrappers for 2461 `tt_hvadvance_adjust'. 2462 2463 * src/truetype/ttdriver.c (tt_service_metrics_variations): Updated. 2464 24652017-02-05 Werner Lemberg <wl@gnu.org> 2466 2467 [autofit] Use better blue zone characters for lowercase latin. 2468 2469 The number of lowercase characters for computing the top flat blue 2470 zone value was too small (in most cases only `x' and `z').
