Their implementations in src/base/ 94 ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar. 95 96 Some macros in otvcommn.h assume the exist of the variable 97 `valid' typed as OTV_Validator in the caller. 98 99 Mixing these two conventions cause invalid pointer conversion 100 and unexpected SEGV in longjmp. To prevent it, all variables 101 typed as OTV_Validator are renamed to `otvalid'. 102 103 * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'. 104 * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c, 105 otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid' 106 if it is typed as OTV_Validator. 107 108 2014-12-09 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 109 110 [ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros. 111 112 Original patch is designed by Werner Lemberg.

This improves 1836 hinting of slanted fonts (especially if the inner parts of serifs 1837 have non-horizontal `shoulders'), avoiding false stem links. 1838 1839 * src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest 1840 stem width (if available) to compute better demerits for distances 1841 between stems. 1842 (af_latin_hints_detect_features): Pass stem width array and

1862 1863 Work around a bug in pkg-config version 0.28 and earlier: If a 1864 variable value gets surrounded by doublequotes (in particular values 1865 for the `prefix' variable), the prefix override mechanism fails. 1866 1867 * builds/unix/freetype2.in: Don't use doublequotes. 1868 * builds/unix/unix-def.in (freetype.pc): Escape spaces in directory 1869 names with backslashes. 1870 1871 2014-03-24 Werner Lemberg <wl (a] gnu.org> 1872 1873 Fix Savannah bug #41946. 1874 1875 Based on a patch from Marek Kak <mkasik (a] redhat.com>. 1876 1877 * builds/unix/configure.raw (LIBS_CONFIG): Remove. 1878 * builds/unix/freetype-config.in (libs): Hard-code value. 1879 * builds/unix/unix-def.in: Updated. 1880 1881 2014-03-22 Werner Lemberg <wl (a] gnu.org> 1882 1883 Another revert for the

<wl (a] gnu.org> 2021 2022 Minor fix for `make devel'. 2023 2024 * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Don't use 2025 pkg-config for bzip2 since not all GNU/Linux distributions have 2026

The data itself gets then parsed line by line, simply 2172 increasing the current pointer into the buffer; if the search for 2173 the final newline character exceeds the buffer size, more data gets 2174 read. 2175 2176 However, in case the current line's end is very near to the buffer 2177 end, and the keyword to compare with is longer than the current 2178 line's length, an out-of-bounds read

The effect 3491 is to use a previous darkening amount when producing an unhinted, 3492 unscaled outline. This can cause autohint samples in ftgrid and 3493 ftview to be based on darkened CFF outlines instead of unhinted, 3494 undarkened ones. 3495 3496 2013-09-29 Dave Arnold <darnold (a] adobe.com> 3497 3498 Fix Savannah bug #39295. 3499 3500 The bug was caused by switching to the initial hintmap (the one in 3501 effect when `moveto' executes) just before drawing the final element 3502 in the charstring. This ensured that the path was closed (in both 3503 Character Space and Device Space). But if the final element was a 3504 curve and if the final hintmap was different enough from the initial 3505 one, then the curve was visibly distorted. 3506 3507 The first part of the fix is to draw the final curve using the final 3508 hintmap as specified by the charstring. This corrects the 3509 distortion but does not ensure closing in Device Space. It may 3510 require the rasterizer to automatically generate an extra closing 3511 line. Depending on the hintmap differences, this line could be from 3512 zero to a couple pixels in length. 3513 3514 The second part of the fix covers the case where the charstring 3515 subpath is closed with an explicit line. We now modify that line's 3516 end point to avoid the distortion. 3517 3518 Some glyphs in the bug report font (TexGyreHeros-Regular) that show 3519 the change are: 3520 3521 25ppem S (98) 3522 24ppem eight (52) 3523 25.5ppem p (85) 3524 3525 Curves at the *end* of a subpath are no longer distorted. However, 3526 some of these glyphs have bad hint substitutions in the middle of a 3527 subpath, and these are not affected. 3528 3529 The patch has been tested with a set of 106 fonts that shipped with 3530 Adobe Creative Suite 4, together with 756 Open Source CFF fonts from 3531 Google Fonts. There are 1.5 million glyphs, of which some 20k are 3532 changed with the fix.

It is available 4454 in Thumb-2 mode, though. 4455 4456 - The header was written a long time ago before Thumb-2 became 4457 widely popular (e.g. with Android). So it simply doesn't use the 4458 assembly routine if the `__thumb__' built-in macro is defined. 4459 4460 - When compiling in Thumb-2 mode, the compiler will define both 4461 `__thumb__' and `__thumb2__'. 4462 4463 By checking for `(__thumb2__ || !__thumb__)', we ensure that the 4464 assembly routine is only avoided when generating Thumb-1 code. 4465 4466 Given that this is performance-sensitive function, this improves 4467 `ftbench' as follows on a Galaxy Nexus: 4468 4469 Before (us/op) After (us/op) 4470 4471 -
