variable. 163 164 2018-01-07 Ewald Hew <ewaldhew (a] gmail.com> 165 166 [psaux] Fix Type 1 glyphs with too many stem hints. 167 168 According to the CFF specification, charstrings can have up to 96 stem 169 hints. Due to hint replacement routines in Type 1 charstrings, some 170 glyphs are rejected by the Adobe engine, which implements the above 171 limit. This fix turns off hinting for such glyphs. 172 173 * src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling 174 `cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off 175 hinting. 176 177 2018-01-06 Werner Lemberg <wl (a] gnu.org> 178 179 Add `FT_Done_MM_Var'. 180 181 This is necessary in case the application's memory routines differ 182 from FreeType. A typical example is a Python application on Windows 183 that calls FreeType compiled as a DLL via the `ctypes' interface. 184 185 * include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare 186 and define. 187 188 * docs/CHANGES: Updated. 189 190 2018-01-03 Werner Lemberg <wl (a] gnu.org> 191 192 [truetype] Round offsets of glyph components only if hinting is on. 193 194 * src/truetype/ttgload.c (TT_Process_Composite_Component): Implement 195 it. 196 197 2018-01-03 Werner Lemberg <wl (a] gnu.org> 198 199 * src/truetype/ttgxvar.c (ft_var_to_design): Remove dead code. 200 201 This is a better fix than the previous commit, which is now 202 reverted. 203 204 2018-01-03 Alexei Podtelezhnikov <apodtele (a] gmail.com> 205 206 Move internal LCD-related declarations. 207 208 * include/freetype/ftlcdfil.h (ft_lcd_padding, ft_lcd_filter_fir): 209 Move from here... 210 * include/freetype/internal/ftobjs.h: ... to here. 211 212 2018-01-03 Alexei Podtelezhnikov <apodtele (a] gmail.com> 213 214 * include/freetype/config/ftconfig.h (FT_EXPORT, FT_EXPORT_DEF) 215 [_MSC_VER]: Limit Visual C++ attributes. 216 217 2018-01-03 Werner Lemberg <wl (a] gnu.org> 218 219 [truetype] Make blend/design coordinate round-tripping work. 220 221 Behdad reported that setting blend coordinates, then getting design 222 coordinates did incorrectly return the default instance's 223 coordinates. 224 225 * src/truetype/ttgxvar.c (tt_set_mm_blend): Fix it. 226 227 2017-12-31 Werner Lemberg <wl (a] gnu.org> 228 229 * src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix endless loop. 230 231

src/base/ftbitmap.c (ft_bitmap_assure_buffer): Make `pitch' and 268 `new_pitch' unsigned. 269 270 * src/base/ftpsprop.c: Include FT_INTERNAL_POSTSCRIPT_PROPS_H. 271 272 2017-12-27 Werner Lemberg <wl (a] gnu.org> 273 274 Fixes for `make multi'. 275 276 * include/freetype/internal/ftpsprop.h: Use `FT_BASE_CALLBACK'. 277 (ps_property_get): Harmonize declaration with corresponding 278 function typedef. 279 280 * include/freety[e/internal/fttrace.h: Add `trace_psprops'. 281 282 * src/base/ftpsprop.c: Include necessary header files. 283 (FT_COMPONENT): Define. 284 (ps_property_set): Tag with `FT_BASE_CALLBACK_DEF'. 285 (ps_property_get): Tag with `FT_BASE_CALLBACK_DEF'. 286 Harmonize declaration with corresponding function typedef. 287 288 2017-12-27 Werner Lemberg <wl (a] gnu.org> 289 290 Provide support for intra-module callback functions. 291 292 This is needed especially for `make multi' with C++. 293 294 * include/freetype/config/ftconfig.h (FT_BASE_CALLBACK, 295 FT_BASE_CALLBACK_DEF): New macros. 296 297 2017-12-25 Ewald Hew <ewaldhew (a] gmail.com> 298 299 Move PostScript drivers' property handlers to `base'. 300 301 This reduces the amount of duplicated code across PostScript 302 drivers. 303 304 * src/cff/cffdrivr.c, src/cid/cidriver.c, src/type1/t1driver.c 305 ({cff,cid,t1}_property_{get,set}): Moved to... 306 * include/freetype/internal/ftpsprop.h: ...this new file. 307 (ps_property_{get,set}): New functions to replace moved ones. 308 309 * src/base/ftpsprop.c: New file that implements above functions. 310 311 * include/freetype/internal/internal.h 312 (FT_INTERNAL_POSTSCRIPT_PROPS_H): New macro. 313 314 * src/cff/cffdrivr.c, src/cid/cidriver.c, src/type1/t1driver.c: 315 Updated. 316 317 * src/base/Jamfile, src/base/rules.mk (BASE_SRC), src/base/ftbase.c: 318 Updated. 319 320 2017-12-20 Werner Lemberg <wl (a] gnu.org> 321 322 Speed up FT_Set_Var_{Design,Blend}_Coordinates if curr == new. 323 324 We exit early if the current design or blend coordinates are 325 identical to the new ones. 326 327 * src/truetype/ttgxvar.c (tt_set_mm_blend, TT_Set_Var_Design): 328 Implement it, returning internal error code -1 if there will be no 329 variation change. 330 331 * src/type1/t1load.c (t1_set_mm_blend): Ditto. 332 333 * src/base/ftmm.c (FT_Set_Var_Design_Coordinates, 334

font of the report that exhibits the bug has a 341 very unusual type 2 cmap for Unicode(!): It contains only two 342 sub-headers, one for one-byte characters (covering the range 0x20 to 343 0xFA), and a second one for higher byte 0x01 (just for character 344 code U+0131). 345 346 Before this commit, the iterator wasn't able to correctly handle a 347 sub-header for higher byte 0x01. 348 349 * src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment 350 for outer loop. 351 352 2017-12-18 Matthias Clasen <matthias.clasen (a] gmail.com> 353 354 [truetype] Fix clamping, minor tracing code beautification. 355 356 * src/truetype/ttgxvar.c (ft_var_to_normalized): Trace number of 357 design coordinates. 358 Use clamped value. 359 360 2017-12-18 Werner Lemberg <wl (a] gnu.org> 361 362 * src/*/*: Only use `ft_' and `FT_' variants of stdc library stuff. 363 364 2017-12-18 Werner Lemberg <wl (a] gnu.org> 365 366 * src/truetype/ttgxvar.c (tt_face_vary_cvt): Add size guard (#52688). 367 368 2017-12-18 Werner Lemberg <wl (a] gnu.org> 369 370 [truetype] Fix previous commit. 371 372 * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Correctly handle 373 unhinted phantom points, which must be properly scaled. 374 375 2017-12-18 Werner Lemberg <wl (a] gnu.org> 376 377 [truetype] Don't apply HVAR and VVAR deltas twice (#52683). 378 379 * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Always adjust 380 `pp1' to `pp4', except if we have an HVAR and/or VVAR table. 381 382 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Handle 383 alternative code branch identically w.r.t. presence of an HVAR 384 and/or VVAR table. 385 386 2017-12-17 Jonathan Kew <jfkthame (a] gmail.com> 387 388 [truetype] Correctly handle variation font phantom points (#52683). 389 390 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix phantom 391 point indices. 392 393 2017-12-17 Jonathan Kew <jfkthame (a] gmail.com> 394 395 Fix incorrect advance width

builds/windows/vc2010/freetype.vcxproj: AfterBuild copy. 403 * objs/.gitignore: Ignore almost everything. 404 405 2017-12-11 Werner Lemberg <wl (a] gnu.org> 406 407 Fix compiler warning (#52640). 408 409 * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Remove unused 410 variable. 411 412 2017-12-08 Azzuro <azzuro (a] team-mediaportal.com> 413 414 * builds/windows/vc2010/freetype.vcxproj: Adjust

Type 1 requires large integers to be followed by 1276 `div'; cf. `Adobe Type 1 Font Format', section 6.2. 1277 <op == 255>: Push Type 1 four-byte numbers as `Int' always. This is 1278 to ensure `div' and `callsubr' get values they can use. 1279 1280 2017-09-25 Ewald Hew <ewaldhew (a] gmail.com> 1281 1282 [psaux] Extend Adobe interpreter (hints). 1283 1284 * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, 1285 cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode. 1286 Allow adding hints mid-charstring. 1287 <cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands 1288 for three normal stem hints.

This is used in the 1379 interpreter to access Private dict data, which are stored in 1380 different places for Type 1 and CFF.

Tytgat <John.Tytgat (a] esko.com> 1905 1906 [cff] Fix family name logic of pure CFF fontdata (#52056). 1907 1908 1. If `FamilyName' is present in the CFF font, use this for 1909 FT_Face's `family_name'. 1910 2. Otherwise, use the face name and chop off any subset prefix. 1911 3. If at this point FT_Face's `family_name' is set, use this 1912 together with the full name to determine the style. 1913 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 1914 5. If we don't have a valid style, use "Regular". 1915 1916 Previously, FT_Face's `family_name' entry for pure CFF fontdata 1917 nearly always was the fontname itself, instead of the `FamilyName' 1918 entry in the CFF font (assuming there is one). 1919 1920 * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it. 1921 1922 2017-09-18 Alexei Podtelezhnikov <apodtele (a] gmail.com> 1923 1924 [build] Declutter Visual C++ 2010-2017 project. 1925 1926 * build/windows/vc2010/freetype.vcxproj: Use MaxSpeed (/02) 1927 optimization for Release configuration throughout the project. 1928 1929 2017-09-16 Werner Lemberg <wl (a] gnu.org> 1930 1931 * Version 2.8.1 released. 1932 ========================= 1933 1934 1935 Tag sources with `VER-2-8-1'. 1936 1937 * docs/VERSION.TXT: Add entry for version 2.8.1. 1938 * docs/CHANGES: Updated. 1939 1940 * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, 1941 builds/windows/vc2005/index.html, 1942 builds/windows/vc2008/freetype.vcproj, 1943 builds/windows/vc2008/index.html, 1944 builds/windows/vc2010/freetype.vcxproj, 1945 builds/windows/vc2010/index.html, 1946 builds/windows/visualc/freetype.dsp, 1947 builds/windows/visualc/freetype.vcproj, 1948 builds/windows/visualc/index.html, 1949 builds/windows/visualce/freetype.dsp, 1950 builds/windows/visualce/freetype.vcproj, 1951 builds/windows/visualce/index.html, 1952 builds/wince/vc2005-ce/freetype.vcproj, 1953 builds/wince/vc2005-ce/index.html, 1954 builds/wince/vc2008-ce/freetype.vcproj, 1955 builds/wince/vc2008-ce/index.html: s/2.8/2.8.1/, s/28/281/. 1956 1957 * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. 1958 1959 * builds/unix/configure.raw (version_info): Set to 21:0:15. 1960 * CMakeLists.txt (VERSION_PATCH): Set to 1. 1961 1962 2017-09-13 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 1963 1964 [sfnt] lowest gcc for vectors (e1d0249e) is changed to 4.7. 1965 1966 __builtin_shuffle() was introduced in gcc-4.7.

Inside Macintosh: More Macintosh Toolbox, `Resource IDs' 2031 (1-46), tells that some IDs are reserved and should not be used. 2032 FreeType2 just uses resource ID to sort the fragmented resource. 2033 To accept the marginal fonts, the checking is removed. 2034 2035 * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id 2036 validity check, fix a trace message format. 2037 2038 2017-09-08 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 2039 2040 [sfnt, truetype] Register the tags for marginal fonts. 2041 2042 The first 32bit of standard TrueType variants is 0x00010000, 2043 `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac 2044 OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources 2045 starting 0xA5 followed by `kbd' or `lst'. Considering the following 2046 data could be parsed as conventional TrueType fonts, the header 2047 checking is updated to allow these tags. It seems that recent Mac 2048 OS X has already switched to normal TTF for these fonts. 2049 2050 See the discussion at 2051 http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 2052 2053 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header 2054 tags for Keyboard.dfont and LastResort.dfont. 2055 * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource 2056 starts with TTAG_0xA5kbd or TTAG_0xA5lst. 2057 * src/truetype/ttobjs.c (tt_face_init): Accept the face with the 2058 format tag is TTAG_0xA5kbd or TTAG_0xA5lst. 2059 2060 2017-09-05 Werner Lemberg <wl (a] gnu.org> 2061 2062 Fix multiple calls of `FT_Bitmap_Convert'. 2063 2064 The documentation of `FT_Bitmap_Convert' says that multiple calls do 2065 proper reallocation of the target FT_Bitmap object. However, this 2066 failed for the sequence 2067 2068 non-empty bitmap 2069 empty bitmap 2070 non-empty bitmap 2071 2072 Reason was that `FT_Bitmap_Convert' only reallocated the bitmap 2073 buffer if it became too small; it didn't make the buffer smaller. 2074 For an empty bitmap following a non-empty one, only the buffer 2075 dimension got set to zero, without deallocation. If the next call 2076 was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was 2077 triggered. 2078 2079 * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target 2080 buffer to the correct size. 2081 2082 * docs/CHANGES: Document it. 2083 2084 2017-09-05 Werner Lemberg <wl (a] gnu.org> 2085 2086 [bdf] Fix size and resolution handling. 2087 2088 * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if 2089 `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are 2090 missing. 2091 2092 * docs/CHANGES: Document it. 2093 2094 2017-08-25 Alexei Podtelezhnikov <apodtele (a] gmail.com> 2095 2096 Swap `ALLOC_MULT' arguments (#51833). 2097 2098 * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated. 2099 * src/winfonts/winfnt.c (FNT_Load_Glyph): Updated. 2100 * src/raster/ftrend1.c (ft_raster1_render): Updated. 2101 2102 2017-08-23 Werner Lemberg <wl (a] gnu.org> 2103 2104 [sfnt] Fix clang compilation (#51788). 2105 2106 * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of 2107 scalars. 2108 (vector_shuffle): New macro to take care of a different built-in 2109 function name on clang. 2110 2111 2017-08-22 Werner Lemberg <wl (a] gnu.org> 2112 2113 [base] Don't zero out allocated memory twice (#51816). 2114 2115 Patch applied from bug report. 2116 2117 * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to 2118 avoid unnecessary overhead. 2119 2120 2017-08-22 Werner Lemberg <wl (a] gnu.org> 2121 2122 [truetype] Integer overflow. 2123 2124 Changes triggered by 2125 2126 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107 2127 2128 * src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use 2129 NEG_LONG. 2130 2131 2017-08-17 Alexei Podtelezhnikov <apodtele (a] gmail.com> 2132 2133 [sfnt] Avoid synthetic unicode for symbol fonts with PUA. 2134 2135 Reported as 2136 2137 https://bugs.chromium.org/p/chromium/issues/detail?id=754574 2138 2139 * src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL. 2140 2141 2017-08-16 Werner Lemberg <wl (a] gnu.org> 2142 2143 * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings. 2144 2145 2017-08-15 Behdad Esfahbod <behdad (a] behdad.org> 2146 2147 [sfnt] Speed up PNG image loading. 2148 2149 This reduces the overhead of `premultiply_data' by 60%. 2150 2151 * src/sfnt/pngshim.c (premultiply_data): Provide code which uses 2152 gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a 2153 time. 2154 2155 2017-08-11 Werner Lemberg <wl (a] gnu.org> 2156 2157 [sfnt, truetype] Improve handling of missing sbits. 2158 2159 Requested by Behdad. 2160 2161 Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain 2162 entries in the bitmap strike(s) for empty glyphs. Instead, they 2163 rely that a space glyph gets created from the font's metrics data. 2164 This commit makes FreeType behave accordingly. 2165 2166 * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error 2167 code. 2168 2169 * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes 2170 to make a distinction between a missing bitmap in a composite and a 2171 simple missing bitmap. 2172 2173 * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a 2174 bitmap-only font), synthesize an empty bitmap glyph if metrics are 2175 available. 2176 2177 2017-08-10 Werner Lemberg <wl (a] gnu.org> 2178 2179 [base] Minor API improvement for default variation axis setting. 2180 2181 * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, 2182 FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, 2183 FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0. 2184 2185 * docs/CHANGES: Updated. 2186 2187 2017-08-08 Werner Lemberg <wl (a] gnu.org> 2188 2189 [psnames] Really fix issue #49949. 2190 2191 We now use a separate preprocessor macro to handle both definition 2192 and declaration of the glyph name arrays. 2193 2194 * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. 2195 2196 * src/tools/glnames.py (StringTable::dump, 2197 StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. 2198 (dump_encoding): Ditto. 2199 (main): Use `wb' mode for writing the output file, which works on 2200 Windows also. 2201 2202 * src/psnames/pstables.h: Regenerated. 2203 2204 2017-08-08 Alexei Podtelezhnikov <apodtele (a] gmail.com> 2205 2206 [smooth] Harmony LCD rendering. 2207 2208 This is a new technology for LCD-optimized rendering. It capitalizes 2209 on the fact that each color channel grid is shifted by a third of a 2210 pixel. Therefore it is logical to render 3 separate monochrome 2211 bitmaps shifting the outline by 1/3 pixel, and then combine them. 2212 Importantly, the resulting output does not require additional LCD 2213 filtering. 2214 2215 * src/smooth/ftsmooth.c (ft_smooth_render_generic) 2216 [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized 2217 rendering. 2218 2219 * include/freetype/ftlcdfil.h, include/freetype/freetype.h, 2220 include/freetype/config/ftoption.h, devel/ftoption.h: Updated 2221 documentation. 2222 2223 2017-08-08 Alexei Podtelezhnikov <apodtele (a] gmail.com> 2224 2225 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up. 2226 2227 2017-08-08 Alexei Podtelezhnikov <apodtele (a] gmail.com> 2228 2229 * src/sfnt/ttpost.c (format): Use otspec-compliant versions. 2230 2231 2017-08-05 Werner Lemberg <wl (a] gnu.org> 2232 2233 [truetype] Integer overflow. 2234 2235 Reported as 2236 2237 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2868 2238 2239 * src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG. 2240 2241 2017-08-05 Werner Lemberg <wl (a] gnu.org> 2242 2243 [base, truetype] New function `FT_Get_Var_Axis_Flags'. 2244 2245 The reserved `flags' field got a value in OpenType version 1.8.2; 2246 unfortunately, the public `FT_Var_Axis' structure misses the 2247 corresponding element.

the first of a series of 2887 similar commits to handle known integer overflows. Basically, all 2888 of them are harmless, since they affect rendering of glyphs only, 2889 not posing security threats. It is expected that fuzzying will show 2890 up more overflows, to be fixed in due course. 2891 2892 The idea is to mark places where overflows can occur, using macros 2893 that simply cast to unsigned integers, because overflow arithmetic 2894 is well defined in this case. Doing so suppresses run-time errors 2895 of sanitizers without adding computational overhead. 2896 2897 * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, 2898 OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, 2899 OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. 2900 2901 * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, 2902 FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, 2903 ft_corner_orientation): Use new macros. 2904 2905 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. 2906 2907 2017-05-28 Werner Lemberg <wl (a] gnu.org> 2908 2909 * include/freetype/internal/ftcalc.h (FLOAT_TO_FIXED): Remove. 2910 2911 This macro is not used. 2912 2913 2017-05-28 Werner Lemberg <wl (a] gnu.org> 2914 2915 [cff] s/cf2_floatToFixed/cf2_doubleToFixed/. 2916 2917 The new name better describes what the macro actually does; 2918 additionally, we don't need a trailing `f' for literals (there was 2919 only a single such instance in the code, but this caused a clang 2920 warning because the macro itself uses `double' literals). 2921 2922 * src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h, 2923 src/cff/cf2font.c, src/cff/cf2hints.c: Updated. 2924 2925 2017-05-28 Werner Lemberg <wl (a] gnu.org> 2926 2927 Fix negation of INT_MIN and LONG_MIN (#46149). 2928 2929 * src/base/ftcalc.c (FT_MOVE_SIGN): Add argument to pass unsigned 2930 value, to be used as the result. 2931 (FT_MulDiv, FT_MulDiv_No_Round, FT_DivFix, FT_MulFix, 2932 FT_Vector_NormLen): Updated. 2933 2934 2017-05-27 Werner Lemberg <wl (a] gnu.org> 2935 2936 [truetype] Fix handling of design coordinates (#51127). 2937 2938 * src/truetype/ttgxvar.c (tt_set_mm_blend): Compute all design 2939 coordinates if we have to create the `blends->coord' array. 2940 (TT_Get_MM_Blend, TT_Get_Var_Design): Select default instance 2941 coordinates if no instance is selected yet. 2942 2943 2017-05-24 Werner Lemberg <wl (a] gnu.org> 2944 2945 [bdf, pcf] Support ISO646.1991-IRV character encoding (aka ASCII). 2946 2947 Problem reported by Marek Kak <mkasik (a] redhat.com>, cf. 2948 2949 https://bugzilla.redhat.com/show_bug.cgi?id=1451795 2950 2951 * src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdrivr.c 2952 (PCF_Face_Init): Implement it. 2953 2954 2017-05-20 Nikolaus Waxweiler <madigens (a] gmail.com> 2955 2956 [truetype] Always use interpreter v35 for B/W rendering (#51051). 2957 2958 * src/truetype/ttgload.c (tt_loader_init) 2959 [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Adjust 2960 `subpixel_hinting_lean', `grayscale_cleartype', and 2961 `vertical_lcd_lean' accordingly. 2962 2963 * src/truetype/ttinterp.c (Ins_GETINFO): Updated. 2964 (TT_RunIns): Update `backward_compatibility' flag. 2965 2966 2017-05-20 Alexei Podtelezhnikov <apodtele (a] gmail.com> 2967 2968 [smooth] Implement minimal dynamic padding for LCD filtering. 2969 2970 Extra bitmap padding for LCD filtering depends on the filter.

4341 2017-02-13 Werner Lemberg <wl (a] gnu.org> 4342 4343 [autofit] Prevent overlapping blue zones. 4344 4345 Problem reported as 4346 4347 https://github.com/google/fonts/issues/632 4348 4349 The font in question (Nunito) has values 705 and 713 for the 4350 reference and overshoot values, respectively, of the first blue 4351 zone. Blue zone 2, however, has value 710 for both the reference 4352 and overshoot. At 12ppem, reference and overshoot of blue zone 0 4353 becomes 8px, while blue zone 2 becomes 9px. 4354 4355 A peculiarity of this font is that the tops of isolated vertical 4356 stems like `N' have a slight overshoot also. The auto-hinter tries 4357 to find the nearest blue zone using the *original* coordinates. For 4358 vertical stems, this is value 713. For normal horizontal tops like 4359 in character `E', this is value 710. Since value 713 is mapped to 4360 8px but value 710 to 9px, `N' and similar characters are one pixel 4361 higher than `E', which looks very bad. 4362 4363 This commit sanitizes blue zones to avoid such a behaviour. 4364 4365 * src/autofit/aflatin.c (af_latin_sort_blue): New function. 4366 (af_latin_metrics_init_blues): Sort blue values and remove overlaps. 4367 4368 2017-02-12 Alexei Podtelezhnikov <apodtele (a] gmail.com> 4369 4370 * src/smooth/ftgrays.c (gray_sweep): Improve code. 4371 4372 2017-02-06 Werner Lemberg <wl (a] gnu.org> 4373 4374 [truetype] Implement `VVAR' table support. 4375 4376 * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to... 4377 (GX_HVVarTable): ...This. 4378 (GX_Blend): Add fields for `VVAR' table handling. 4379 Other minor updates. 4380 4381 * src/truetype/ttgxvar.c (ft_var_load_hvar): Renamed to... 4382 (ft_var_load_hvvar): ...This. 4383 Handle VVAR loading also (controlled by an additional parameter). 4384 (tt_hadvance_adjust): Renamed to... 4385 (tt_hvadvance_adjust): ...This. 4386 Handle application of advance height also (controlled by an 4387 additional parameter). 4388 (tt_hadvance_adjust, tt_vadvance_adjust): Wrappers for 4389 `tt_hvadvance_adjust'. 4390 4391 * src/truetype/ttdriver.c (tt_service_metrics_variations): Updated. 4392 4393 2017-02-05 Werner Lemberg <wl (a] gnu.org> 4394 4395 [autofit] Use better blue zone characters for lowercase latin. 4396 4397 The number of lowercase characters for computing the top flat blue 4398 zone value was too small (in most cases only `x' and `z'). If one 4399 of the two characters has a large serif, say, it can happen that 4400 FreeType must select between two different values, having a 50% 4401 chance to use the wrong one. As a result, rendering at larger PPEM 4402 values could yield uneven lowercase glyph heights. 4403 4404 Problem reported by Christoph Koeberlin <christoph (a] koe.berlin>. 4405 4406 * src/autofit/afblue.dat (AF_BLUE_STRING_LATIN_SMALL): Replaced 4407 with... 4408 (AF_BLUE_STRING_LATIN_SMALL_TOP, AF_BLUE_STRING_LATIN_SMALL_BOTTOM): 4409 ...
