1.56 +
1.57 +2014-03-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.58 +

1.63 +
1.64 +2014-03-04 Werner Lemberg <wl@gnu.org>
1.65 +
1.66 + Minor fix for `make devel'.
1.67 +
1.68 + * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Don't use
1.69 + pkg-config for bzip2 since not all GNU/Linux distributions have
1.70 + `bzip2.pc' (and the header file `bzlib.h' is located in /usr/include
1.71 + normally).
1.72 +
1.73 +2014-03-04 Sean McBride <sean@rogue-research.com>

1.86 +
1.87 +2014-03-03 Werner Lemberg <wl@gnu.org>
1.88 +
1.89 + Rewrite library option handling in `configure'.
1.90 +
1.91 + o Introduce `auto' value for `--with-XXX' library options; this is
1.92 + now the default.
1.93 +
1.94 + o First use `pkg-config' for library detection, then fall back to
1.95 + other tests.
1.96 +
1.97 + * builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,
1.98 + --with-harfbuzz): Rewrite.
1.99 + Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf'
1.100 + variables to collect data for `freetype2.pc' and `freetype-config'.
1.101 + (FT2_EXTRA_LIBS): Renamed to ...
1.102 + (ft2_extra_libs): This since it gets no longer substituted.
1.103 + (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBS_CONFIG, LIBSSTATIC_CONFIG):
1.104 + New output variables, replacing `XXX_PKG' and `LIBXXX'.
1.105 + Add notice at the end of `configure' showing the library
1.106 + configuration.
1.107 +
1.108 + * builds/unix/freetype-config.in (--static): New command line
1.109 + option.
1.110 + (libs): Updated.
1.111 + (staticlibs): New variable, to be used if `--static' is given.
1.112 + * builds/doc/freetype-config.1: Document `--static'.
1.113 +
1.114 + * builds/unix/freetype2.in, builds/unix/unix-def.in: Updated.
1.115 +
1.116 +2014-03-01 Werner Lemberg <wl@gnu.org>
1.117 +
1.118 + Avoid `long long' warnings with older gcc compilers.
1.119 + Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
1.120 +
1.121 + * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for
1.122 + versions < 4.6. This is especially needed for Max OS X since this
1.123 + OS runs a gcc variant (or emulation) based on version 4.2.1.
1.124 +
1.125 +2014-03-01 Werner Lemberg <wl@gnu.org>
1.126 +
1.127 + * docs/INSTALL.CROSS: Revised and updated.
1.128 +
1.129 +2014-03-01 Werner Lemberg <wl@gnu.org>
1.130 +
1.131 + Make `make clean' remove `freetype2.pc'.
1.132 +
1.133 + This is a generated file at build time, not configure time.
1.134 +
1.135 + * builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ...
1.136 + (CLEAN): This variable.
1.137 +
1.138 +2014-03-01 Werner Lemberg <wl@gnu.org>
1.139 +
1.140 + Use pkg-config for detecting libpng and libbz2 also.
1.141 +
1.142 + * builds/unix/configure.raw (HAVE_PKG): New variable.
1.143 + Search for libbz2 using `pkg-config'; s/BZ2/BZIP2/.
1.144 + Search for libpng using `pkg-config'.
1.145 + Fix definition of `LIBHARFBUZZ' variable.
1.146 + * builds/unix/freetype-config.in ($libs): Updated.
1.147 + * builds/unix/freetype2.in: Add `URL' field.
1.148 + Update `Requires.private' and `Libs.private'.
1.149 + * builds/unix/unix-def.in: Updated.
1.150 +
1.151 +2014-03-01 Werner Lemberg <wl@gnu.org>
1.152 +
1.153 + Add configure support for HarfBuzz.
1.154 +
1.155 + * builds/unix/pkg.m4: New file.
1.156 + * builds/unix/configure.raw: Search for libharfbuzz using
1.157 + `pkg-config'.
1.158 + Add `--without-harfbuzz' option.
1.159 + * builds/unix/freetype-config.in, builds/unix/freetype2.in,
1.160 + builds/unix/unix-def.in (freetype-config, freetype2.pc): Handle
1.161 + HarfBuzz.
1.162 +
1.163 + * docs/INSTALL.UNIX: Document interdependency of Freetype with
1.164 + HarfBuzz.
1.165 +
1.166 +2014-02-28 Alexei Podtelezhnikov <apodtele@gmail.com>
1.167 +
1.168 + [cff] Math simplifications.
1.169 +
1.170 + * src/cf2blues.c (cf2_blues_init): Use `FT_MulDiv'.
1.171 + * src/cf2ft.c (cf2_getScaleAndHintFlag): Use simple division.
1.172 +
1.173 +2014-02-28 Dave Arnold <darnold@adobe.com>
1.174 +
1.175 + [cff] Fix Savannah bug #41697, part 2.
1.176 +
1.177 + * src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
1.178 + cf2_initGlobalRegionBuffer): It is possible for a charstring to call
1.179 + a subroutine if no subroutines exist. This is an error but should
1.180 + not trigger an assert. Split the assert to account for this.
1.181 +
1.182 +2014-02-28 Dave Arnold <darnold@adobe.com>
1.183 +
1.184 + [cff] Fix Savannah bug #41697, part 1.
1.185 +
1.186 + * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is
1.187 + invalid. In this case, it is not safe to use the length of
1.188 + `hStemHintArray'; the exception has already been recorded in
1.189 + `hintMask'.
1.190 +
1.191 +2014-02-26 Werner Lemberg <wl@gnu.org>
1.192 +
1.193 + [sfnt] Fix Savannah bug #41696.
1.194 +
1.195 + * src/sfnt/ttcmap.c (tt_cmap0_validate, tt_cmap2_validate,
1.196 + tt_cmap4_validate, tt_cmap14_validate): Fix limit tests.
1.197 +
1.198 +2014-02-26 Werner Lemberg <wl@gnu.org>
1.199 +
1.200 + [winfnt] Fix Savannah bug #41694.
1.201 +
1.202 + * src/winfonts/winfnt.c (FNT_Load_Glyph): Check glyph offset.
1.203 +
1.204 +2014-02-26 Werner Lemberg <wl@gnu.org>
1.205 +
1.206 + [cff] Fix Savannah bug #41693.
1.207 +
1.208 + * src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array.
1.209 +
1.210 +2014-02-26 Werner Lemberg <wl@gnu.org>
1.211 +
1.212 + [bdf] Fix Savannah bug #41692.
1.213 +
1.214 + bdflib puts data from the input stream into a buffer in chunks of
1.215 + 1024 bytes. The data itself gets then parsed line by line, simply
1.216 + increasing the current pointer into the buffer; if the search for
1.217 + the final newline character exceeds the buffer size, more data gets
1.218 + read.
1.219 +
1.220 + However, in case the current line's end is very near to the buffer
1.221 + end, and the keyword to compare with is longer than the current
1.222 + line's length, an out-of-bounds read might happen since `memcmp'
1.223 + doesn't stop properly at the string end.
1.224 +
1.225 + * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
1.226 + stop at string ends.
1.227 +
1.228 +2014-02-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1.229 +
1.230 + [autofit] Fix `make multi' compilation.
1.231 +
1.232 + * src/autofit/hbshim.c: Include `afglobal.h' and `aftypes.h'.
1.233 +
1.234 +2014-02-19 Werner Lemberg <wl@gnu.org>
1.235 + Simon Bünzli <zeniko@gmail.com>
1.236 +
1.237 + Fix Savannah bug #32902.
1.238 +
1.239 + Patch taken from
1.240 +
1.241 + https://code.google.com/p/sumatrapdf/source/browse/trunk/ext/_patches/freetype2.patch?spec=svn8620&r=8620#87
1.242 +
1.243 + with slight modifications.
1.244 +
1.245 + * src/type1/t1parse.c (T1_Get_Private_Dict): Add heuristic test to

1.262 +
1.263 +2014-02-12 Werner Lemberg <wl@gnu.org>
1.264 +
1.265 + Fix Savannah bug #41465.
1.266 +
1.267 + * builds/unix/unix-def.in (CLEAN): Add `freetype-config'.
1.268 + (DISTCLEAN): Remove `freetype-config'.
1.269 +
1.270 +2014-02-08 Sean McBride <sean@rogue-research.com>
1.271 +
1.272 + Fix clang static analyzer and compiler warnings.
1.273 +
1.274 + * src/autofit/afhints.c (af_glyph_hints_align_weak_points),
1.275 + src/autofit/afloader (af_loader_load_g) <FT_GLYPH_FORMAT_COMPOSITE>,
1.276 + src/base/ftcalc.c (FT_MSB), src/base/ftoutln.c

1.286 + af_property_set, af_property_get), src/base/ftbitmap.c
1.287 + (ft_gray_for_premultiplied_srgb_bgra): Make functions static.
1.288 +
1.289 + * src/base/ftobjs.c (ft_remove_renderer): Protect against
1.290 + library == NULL.
1.291 + (ft_property_do): Make function static.
1.292 +
1.293 + * src/base/ftrfork.c: Include `ftbase.h'.
1.294 +

1.303 +
1.304 + Fix Windows build directories.
1.305 +
1.306 + The build target is now `windows' instead of `win32'.
1.307 +
1.308 + Problem reported by Nickolas George <darknova.clan@gmail.com>.
1.309 +
1.310 + * builds/modules.mk: Don't use `win32' and `win16' (!) but
1.311 + `windows'.
1.312 +
1.313 + * builds/windows/detect.mk, builds/windows/win32-def.mk:
1.314 + s/win32/windows/.
1.315 +

1.317 +
1.318 + Fix Savannah bug #41507.
1.319 +
1.320 + * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap)
1.321 + [!FT_CONFIG_OPTION_USE_PNG] <17, 17, 19>: Fix error handling.

1.325 + [cff] Fix minor performance bug.
1.326 +
1.327 + * src/cff/cf2font.c (cf2_font_setup): Darkening amount and blue zone
1.328 + calculations are now cached and not recomputed on each glyph.

1.339 +
1.340 + Fix compilation with MinGW.
1.341 +
1.342 + Right now, compilation out of the box with latest MinGW is broken
1.343 + due to bugs in header files of mingwrt 4.0.3 in strict ANSI mode,
1.344 + cf.
1.345 +
1.346 + https://sourceforge.net/p/mingw/bugs/2024/
1.347 + https://sourceforge.net/p/mingw/bugs/2046/
1.348 +
1.349 + * builds/unix/configure.raw: Don't set `-ansi' flag for MinGW.
1.350 +
1.351 +2014-02-04 Werner Lemberg <wl@gnu.org>
1.352 +

1.370 +2014-01-26 Werner Lemberg <wl@gnu.org>
1.371 +
1.372 + [autofit] Introduce two more slots for standard characters.
1.373 +
1.374 + This is useful for OpenType features like `c2sc' (caps to small
1.375 + caps) that don't have lowercase letters by definition, or other
1.376 + features that mainly operate on numerals.
1.377 +
1.378 + * src/autofit/afscript.h: Add more standard characters.

1.399 +
1.400 +2014-01-23 Werner Lemberg <wl@gnu.org>
1.401 +
1.402 + Fix Savannah bug #41310.
1.403 +
1.404 + * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap) <glyph_format==5>:
1.405 + Don't check metrics, which this format doesn't have.
1.406 + This is another correction to the commit from 2013-11-21.
1.407 +
1.408 +2014-01-23 Werner Lemberg <wl@gnu.org>
1.409 +
1.410 + Fix Savannah bug #41309.
1.411 +
1.412 + * src/type1/t1load.c (t1_parse_font_matrix): Properly handle result
1.413 + of `T1_ToFixedArray'.

1.415 + * src/cid/cidload.c (cid_parse_font_matrix): Synchronize with
1.416 + `t1_parse_font_matrix'.
1.417 +
1.418 + * src/type42/t42parse.c (t42_parse_font_matrix): Synchronize with
1.419 + `t1_parse_font_matrix'.

1.484 +
1.485 + [autofit] Fix Indic scripts.
1.486 +
1.487 + Split the single, incorrect Indic entry into separate scripts so
1.488 + that the covered ranges are the same: Bengali, Devanagari, Gujarati,
1.489 + Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
1.490 + Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove
1.491 + entries for Meetai Mayak and Sharada – the Unicode ranges were
1.492 + incorrect (and nobody has complained about that), fonts are scarce
1.493 + for those scripts, and the Indic auto-hinter support is rudimentary
1.494 + anyways.
1.495 +
1.496 + * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
1.497 + AF_CONFIG_OPTION_CJK.
1.498 +
1.499 + * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
1.500 + Use it, together with AF_CONFIG_OPTION_INDIC and
1.501 + AF_CONFIG_OPTION_CJK, to update.
1.502 +
1.503 + * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
1.504 + [!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.
1.505 + Sort entries by tags.
1.506 +
1.507 +2014-01-03 Werner Lemberg <wl@gnu.org>
1.508 +
1.509 + [autofit] Thinko.
1.510 +
1.511 + * src/autofit/hbshim.c (af_get_char_index): Similar to
1.512 + `af_get_coverage', reject glyphs which are not substituted.
1.513 +
1.514 +2014-01-03 Werner Lemberg <wl@gnu.org>
1.515 +
1.516 + [autofit] Fix handling of default coverages.
1.517 +
1.518 + With this commit, the implementation of coverage handling is
1.519 + completed.
1.520 +
1.521 + * src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to
1.522 + do.
1.523 + Reject coverages which don't contain appropriate glyphs for blue
1.524 + zones.
1.525 +
1.526 +2014-01-03 Werner Lemberg <wl@gnu.org>
1.527 +
1.528 + [autofit] Fix handling of default coverages.
1.529 +
1.530 + * src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
1.531 + First handle non-default coverages, then the default coverage of the
1.532 + default script, and finally the other default coverages.
1.533 +
1.534 +2014-01-03 Werner Lemberg <wl@gnu.org>
1.535 +
1.536 + [autofit] Fix scaling of HarfBuzz shaping.
1.537 +
1.538 + * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM.
1.539 +
1.540 +2014-01-03 Werner Lemberg <wl@gnu.org>
1.541 +
1.542 + [autofit] Better ftgrid support.
1.543 +
1.544 + * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add
1.545 + parameters `is_blue' and `blue_offset'.
1.546 +
1.547 +2014-01-01 Werner Lemberg <wl@gnu.org>
1.548 +
1.549 + [autofit] Remove some styles.
1.550 +
1.551 + * src/autofit/afcover.h: Remove coverages for alternative fractions,
1.552 + denominators, numerators, and fractions.
1.553 +
1.554 + * src/autofit/afstyles.h (META_STYLE_LATIN): Updated.
1.555 +
1.556 +2014-01-01 Werner Lemberg <wl@gnu.org>
1.557 +
1.558 + [autofit] Add more styles.
1.559 +
1.560 + * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New
1.561 + auxiliary macros; use them to define styles for Cyrillic, Greek, and
1.562 + Latin.
1.563 +
1.564 + * src/autofit/afcover.h: Remove coverage for oldstyle figures.
1.565 + Since those digits are used in combination with ordinary letters, it
1.566 + makes no sense to handle them separately.
1.567 +
1.568 + * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit
1.569 + `options' parameter to 4 bits.
1.570 +
1.571 +2014-01-01 Werner Lemberg <wl@gnu.org>
1.572 +

1.578 +
1.579 +2014-01-01 Werner Lemberg <wl@gnu.org>
1.580 +
1.581 + * src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/.

1.583 +2014-01-01 Werner Lemberg <wl@gnu.org>
1.584 +
1.585 + [autofit] Implement and use `af_get_char_index' with HarfBuzz.
1.586 +
1.587 + * src/autofit/hbshim.c (COVERAGE) [FT_CONFIG_OPTION_USE_HARFBUZZ]:
1.588 + Redefine to construct HarfBuzz features.

1.590 +
1.591 + * src/autofit/aflatin.c (af_latin_metrics_init_blues): Use

1.599 +
1.600 + [autofit] Fix interface of `af_get_char_index'.
1.601 +
1.602 + * src/autofit/hbshim.c (af_get_char_index): Return error value.
1.603 + Add argument for y offset (to be used in a yet-to-come patch).
1.604 +
1.605 + * src/autofit/hbshim.h, src/autofit/afcjk.c,
1.606 + src/autofit/aflatin.c: Updated.
1.607 +
1.608 +2013-12-30 Werner Lemberg <wl@gnu.org>
1.609 +
1.610 + [autofit] Don't combine multiple features into one set.
1.611 +
1.612 + Combining them, as originally envisioned, would lead to much more
1.613 + complicated code, as investigations have shown meanwhile. The major
1.614 + drawback is that we run out of available style slots much earlier.
1.615 + However, this is only a theoretical issue since we don't support a
1.616 + large number of scripts currently.
1.617 +
1.618 + * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with
1.619 + a single-element `COVERAGE' macro, sort the elements by the feature
1.620 + tags, and add entry for `ruby'.
1.621 +
1.622 + * src/autofit/aftypes.h: Updated.
1.623 + * src/autofit/hbshim.c: Updated.
1.624 +
1.625 +2013-12-28 Werner Lemberg <wl@gnu.org>

1.633 +

1.638 + unconditionally.
1.639 +
1.640 +2013-12-28 Werner Lemberg <wl@gnu.org>
1.641 +
1.642 + [autofit] Add wrapper function for `FT_Get_Char_Index'.

1.645 + function.
1.646 +

1.656 +
1.657 +2013-12-28 Werner Lemberg <wl@gnu.org>
1.658 +
1.659 + [autofit] Use `global' HarfBuzz font object.
1.660 +
1.661 + We now use `hb_font' instead of `hb_face' since yet-to-come changes
1.662 + need this.
1.663 +
1.664 + * src/autofit/afglobal.h: Include `hbshim.h'.
1.665 + (AF_FaceGlobalsRec) [FT_CONFIG_OPTION_USE_HARFBUZZ]: New member

1.705 +
1.706 + [ftrfork] Fix the face order difference between POSIX and Carbon.
1.707 +
1.708 + The fragmented resources in Suitcase and .dfont should be reordered
1.709 + when `POST' resource for Type1 is being restored, but reordering of
1.710 + sfnt resources induces the different face order. Now the ordering
1.711 + is restricted to `POST' resource only, to prevent the different
1.712 + order issue (e.g. the face index in the fontconfig cache generated
1.713 + with Carbon framework is incompatible with that by FreeType 2
1.714 + without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

1.740 +2013-12-21 Werner Lemberg <wl@gnu.org>
1.741 +
1.742 + [autofit] Introduce `coverages'.
1.743 +
1.744 + Coverages are the interface to the HarfBuzz library to acces
1.745 + OpenType features for handling glyphs not addressable by the cmap.
1.746 +
1.747 + Right now, compilation of HarfBuzz is only added to the development
1.748 + build. A solution for standard build mode will be delayed until
1.749 + HarfBuzz gets split into two libraries to avoid mutual dependencies
1.750 + between FreeType and HarfBuzz.
1.751 +
1.752 + Note that this is only a first step in handling coverages, basically
1.753 + providing the framework only. Code for handling selected OpenType
1.754 + features (this is, actually using the data in `afcover.h') will
1.755 + follow.
1.756 +
1.757 + * devel/ftoption.h, include/config/ftoption.h
1.758 + (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro.
1.759 +
1.760 + * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h:
1.761 + New files.

1.763 + * src/autofit/afscript.h: Add HarfBuzz script name tags.

1.766 +
1.767 + * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.
1.768 + (AF_Coverage): New enumeration (generated by `afcover.h').
1.769 + (AF_StyleClassRec): New member `coverage'.
1.770 + (AF_DEFINE_STYLE_CLASS): Updated.
1.771 +
1.772 + * include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage
1.773 + data.

1.793 +
1.794 + * src/autofit/afranges.h: Update use of `SCRIPT' macro.
1.795 +
1.796 + * src/autofit/autofit.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: Include

1.832 + function name correctly corresponds to what the macro framework
1.833 + expects.
1.834 +
1.835 + * src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so

1.1045 + the glyph (component) by a fractional value computed from the LSB
1.1046 + phantom point. This is wrong, since the horizontal phantom points
1.1047 + get rounded horizontally later on.

1.1085 + [truetype] Next round in phantom point handling.
1.1086 +
1.1087 + Greg Hitchcock provided very interesting insights into the
1.1088 + complicated history of the horizontal positions of the TSB and BSB
1.1089 + phantom points.
1.1090 +
1.1091 + * src/truetype/ttgload.c (TT_LOADER_SET_PP)
1.1092 + [TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and

1.1123 +
1.1124 + This is a further improvement to the changes from 2013-11-06.
1.1125 +

1.1138 + * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to
1.1139 + `Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
1.1140 + `IS_HINTED' clause.
1.1141 + Also remove redundant check using `maxSizeOfInstructions' – in
1.1142 + simple glyphs, the bytecode data comes before the outline data, and
1.1143 + a validity test for this is already present.
1.1144 +
1.1145 +2013-11-27 Werner Lemberg <wl@gnu.org>

1.1261 + Simplify header file hierarchy.
1.1262 +
1.1263 + This large patch changes the header file directory layout from
1.1264 + `include/freetype/...' to `include/...', effectively removing one
1.1265 + level. Since the file `ft2build.h' is also located in `include'
1.1266 + (and it stays there even after installation), all FreeType header
1.1267 + files are now in a single directory.

1.1270 + `pkg-config' file to get the include directory for the compiler, and

1.1272 +
1.1273 + #include <ft2build.h>

1.1492 +
1.1493 + When using `ADD' with an immediate operand, the instruction is

1.1520 +
1.1521 + Note that the old code avoided using a region of the piecewise
1.1522 + linear function where the slope was zero. The recovery was to use a
1.1523 + different section of the function, which produced a different,
1.1524 + incorrect amount of darkening.

1.1532 + * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
1.1533 +
1.1534 + This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
1.1535 + is to use a previous darkening amount when producing an unhinted,
1.1536 + unscaled outline. This can cause autohint samples in ftgrid and
1.1537 + ftview to be based on darkened CFF outlines instead of unhinted,
1.1538 + undarkened ones.
1.1539 +
1.1540 +2013-09-29 Dave Arnold <darnold@adobe.com>
1.1541 +
1.1542 + Fix Savannah bug #39295.
1.1543 +
1.1544 + The bug was caused by switching to the initial hintmap (the one in
1.1545 + effect when `moveto' executes) just before drawing the final element
1.1546 + in the charstring. This ensured that the path was closed (in both
1.1547 + Character Space and Device Space). But if the final element was a
1.1548 + curve and if the final hintmap was different enough from the initial
1.1549 + one, then the curve was visibly distorted.
1.1550 +
1.1551 + The first part of the fix is to draw the final curve using the final
1.1552 + hintmap as specified by the charstring. This corrects the
1.1553 + distortion but does not ensure closing in Device Space. It may
1.1554 + require the rasterizer to automatically generate an extra closing
1.1555 + line. Depending on the hintmap differences, this line could be from
1.1556 + zero to a couple pixels in length.
1.1557 +
1.1558 + The second part of the fix covers the case where the charstring
1.1559 + subpath is closed with an explicit line. We now modify that line's
1.1560 + end point to avoid the distortion.
1.1561 +
1.1562 + Some glyphs in the bug report font (TexGyreHeros-Regular) that show
1.1563 + the change are:
1.1564 +
1.1565 + 25ppem S (98)
1.1566 + 24ppem eight (52)
1.1567 + 25.5ppem p (85)
1.1568 +
1.1569 + Curves at the *end* of a subpath are no longer distorted. However,
1.1570 + some of these glyphs have bad hint substitutions in the middle of a
1.1571 + subpath, and these are not affected.
1.1572 +
1.1573 + The patch has been tested with a set of 106 fonts that shipped with
1.1574 + Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
1.1575 + Google Fonts. There are 1.5 million glyphs, of which some 20k are
1.1576 + changed with the fix. A sampling of a few hundred of these changes
1.1577 + have been examined more closely, and the changes look good (or at
1.1578 + least acceptable).

1.1748 + FT_Open_Face: Improve external stream handling.
1.1749 +
1.1750 + If the font's `clazz->init_face' function wants to swap to new
1.1751 + stream, handling of whether original stream was external could
1.1752 + result to either memory leak or double free. Mark externality into

1.1818 +
1.1819 + Better tracing of loaded glyphs.
1.1820 +
1.1821 + Previously, the loading of a glyph was traced at level 4, if at all.
1.1822 + With this change, all font loading routines emit a tracing message
1.1823 + at level 1, making it easier to select tracing output (for example

1.1944 +
1.1945 + [autofit] Introduce data file for blue strings.
1.1946 +
1.1947 + The idea is to have a central file which gets processed by a Perl
1.1948 + script to create proper `.c' and `.h' files using templates. There
1.1949 + are two other reasons to do that:
1.1950 +
1.1951 + . The data file should be easily readable. We use UTF-8 encoding
1.1952 + which then gets converted to single bytes.
1.1953 +
1.1954 + . Since the number of supported scripts will increase soon, the
1.1955 + current usage of blue string arrays is a waste of space. Using
1.1956 + the Perl script it is possible to imitate jagged arrays,
1.1957 + defining enumeration constants as offsets into the arrays.
1.1958 +
1.1959 + This commit only adds files without changing any functionality.
1.1960 +
1.1961 + * src/autofit/afblue.dat: New data file.
1.1962 + * src/tools/afblue.pl: New Perl script for processing `afblue.dat'.

1.2180 + [autofit] Introduce `writing systems'.
1.2181 +
1.2182 + This patch adds a new top level to the auto-hinter's script class

1.2184 + scripts.
1.2185 +
1.2186 + For example, the `latin' writing system (in file `aflatin.c') is
1.2187 + able to support scripts like Latin, Cyrillic, Armenian, etc., which
1.2188 + can be handled similarly.

1.2488 +
1.2489 + Speed up ARMv7 support.
1.2490 +
1.2491 + When building for ARMv7 with thumb2 instructions, the optimized
1.2492 + `FT_MulFix_arm' assembly routine was not being used.
1.2493 +
1.2494 + The reason for this is in the `ftconfig.h' header, namely:
1.2495 +
1.2496 + - The assembly routine uses the `smull' instruction which is not
1.2497 + available when generating Thumb-1 machine code. It is available
1.2498 + in Thumb-2 mode, though.
1.2499 +
1.2500 + - The header was written a long time ago before Thumb-2 became
1.2501 + widely popular (e.g. with Android). So it simply doesn't use the
1.2502 + assembly routine if the `__thumb__' built-in macro is defined.
1.2503 +
1.2504 + - When compiling in Thumb-2 mode, the compiler will define both
1.2505 + `__thumb__' and `__thumb2__'.
1.2506 +
1.2507 + By checking for `(__thumb2__ || !__thumb__)', we ensure that the
1.2508 + assembly routine is only avoided when generating Thumb-1 code.
1.2509 +
1.2510 + Given that this is performance-sensitive function, this improves
1.2511 + `ftbench' as follows on a Galaxy Nexus:

1.2883 +
1.2884 + http://cppcheck.sourceforge.net/
1.2885 +
1.2886 + The call was (from the top-level of the FreeType tree):
1.2887 +
1.2888 + cppcheck --force \
1.2889 + --enable=all \

1.2894 + . &> cppcheck.log
1.2895 +
1.2896 + Note that the current version heavily chokes on FreeType, delivering
1.2897 + many wrong results. I will report those issues to the cppcheck team
1.2898 + so that a newer version gives improved results hopefully.

1.2939 +
1.2940 + Add support for color embedded bitmaps (eg. color emoji).
1.2941 +
1.2942 + A new load flag, FT_LOAD_COLOR, makes FreeType load color
1.2943 + embedded-bitmaps, following this draft specification
1.2944 +
1.2945 + https://color-emoji.googlecode.com/git/specification/v1.html
1.2946 +
1.2947 + which defines two new SFNT tables, `CBDT' and `CBLC' (named and
1.2948 + modeled after `EBDT' and `EBLC', respectively). The color bitmaps
1.2949 + are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
1.2950 + pre-multiplied sRGB images. If PNG support is available, PNG color
1.2951 + images as defined in the same proposed specification are supported
1.2952 + also.
1.2953 +
1.2954 + Note that color bitmaps are converted to grayscale if client didn't
1.2955 + ask for color.
