| |
| Fix several clang static analyzer dead store warnings. |
| |
| * src/autofit/afhints.c (af_glyph_hints_reload, |
| af_glyph_hints_align_weak_points): Remove unnecessary assignments. |
| |
| * src/bdf/bdflib.c (bdf_font_load): Ditto. |
| |
| * src/pshinter/pshalgo.c (psh_glyph_compute_extrema, |
| psh_glyph_interpolate_other_points): Ditto. |

| |
| Rewrite library option handling in `configure'. |
| |
| o Introduce `auto' value for `--with-XXX' library options; this is |
| now the default. |
| |
| o First use `pkg-config' for library detection, then fall back to |
| other tests. |
| |
| * builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png, |
| --with-harfbuzz): Rewrite. |
| Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf' |
| variables to collect data for `freetype2.pc' and `freetype-config'. |
| (FT2_EXTRA_LIBS): Renamed to ... |
| (ft2_extra_libs): This since it gets no longer substituted. |
| (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBS_CONFIG, LIBSSTATIC_CONFIG): |
| New output variables, replacing `XXX_PKG' and `LIBXXX'. |
| Add notice at the end of `configure' showing the library |
| configuration. |
| |
| * builds/unix/freetype-config.in (--static): New command line |
| option. |
| (libs): Updated. |
| (staticlibs): New variable, to be used if `--static' is given. |
| * builds/doc/freetype-config.1: Document `--static'. |
| |
| * builds/unix/freetype2.in, builds/unix/unix-def.in: Updated. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |
| |
| Avoid `long long' warnings with older gcc compilers. |
| Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. |
| |
| * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for |
| versions < 4.6. This is especially needed for Max OS X since this |
| OS runs a gcc variant (or emulation) based on version 4.2.1. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |
| |
| * docs/INSTALL.CROSS: Revised and updated. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |
| |
| Make `make clean' remove `freetype2.pc'. |
| |
| This is a generated file at build time, not configure time. |
| |
| * builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ... |
| (CLEAN): This variable. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |
| |
| Use pkg-config for detecting libpng and libbz2 also. |
| |
| * builds/unix/configure.raw (HAVE_PKG): New variable. |
| Search for libbz2 using `pkg-config'; s/BZ2/BZIP2/. |
| Search for libpng using `pkg-config'. |
| Fix definition of `LIBHARFBUZZ' variable. |
| * builds/unix/freetype-config.in ($libs): Updated. |
| * builds/unix/freetype2.in: Add `URL' field. |
| Update `Requires.private' and `Libs.private'. |
| * builds/unix/unix-def.in: Updated. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |
| |
| Add configure support for HarfBuzz. |
| |
| * builds/unix/pkg.m4: New file. |
| * builds/unix/configure.raw: Search for libharfbuzz using |
| `pkg-config'. |
| Add `--without-harfbuzz' option. |
| * builds/unix/freetype-config.in, builds/unix/freetype2.in, |
| builds/unix/unix-def.in (freetype-config, freetype2.pc): Handle |
| HarfBuzz. |
| |
| * docs/INSTALL.UNIX: Document interdependency of Freetype with |
| HarfBuzz. |

| * src/cf2ft.c (cf2_getScaleAndHintFlag): Use simple division. |
| |
| 2014-02-28 Dave Arnold <darnold@adobe.com> |
| |
| [cff] Fix Savannah bug #41697, part 2. |
| |
| * src/cff/cf2ft.c (cf2_initLocalRegionBuffer, |
| cf2_initGlobalRegionBuffer): It is possible for a charstring to call |
| a subroutine if no subroutines exist. This is an error but should |
| not trigger an assert. Split the assert to account for this. |
| |
| 2014-02-28 Dave Arnold <darnold@adobe.com> |
| |
| [cff] Fix Savannah bug #41697, part 1. |
| |
| * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is |
| invalid. In this case, it is not safe to use the length of |
| `hStemHintArray'; the exception has already been recorded in |
| `hintMask'. |
| |
| 2014-02-26 Werner Lemberg <wl@gnu.org> |
| |
| [sfnt] Fix Savannah bug #41696. |
| |

| |
| * src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array. |
| |
| 2014-02-26 Werner Lemberg <wl@gnu.org> |
| |
| [bdf] Fix Savannah bug #41692. |
| |
| bdflib puts data from the input stream into a buffer in chunks of |
| 1024 bytes. The data itself gets then parsed line by line, simply |
| increasing the current pointer into the buffer; if the search for |
| the final newline character exceeds the buffer size, more data gets |
| read. |
| |
| However, in case the current line's end is very near to the buffer |
| end, and the keyword to compare with is longer than the current |
| line's length, an out-of-bounds read might happen since `memcmp' |
| doesn't stop properly at the string end. |
| |
| * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons |
| stop at string ends. |
| |

| |
| Fix Windows build directories. |
| |
| The build target is now `windows' instead of `win32'. |
| |
| Problem reported by Nickolas George <darknova.clan@gmail.com>. |
| |
| * builds/modules.mk: Don't use `win32' and `win16' (!) but |
| `windows'. |
| |
| * builds/windows/detect.mk, builds/windows/win32-def.mk: |
| s/win32/windows/. |
| |
| 2014-02-08 Eugen Sawin <esawin@mozilla.com> |

| 2014-02-04 Werner Lemberg <wl@gnu.org> |
| |
| Fix compilation with MinGW. |
| |
| Right now, compilation out of the box with latest MinGW is broken |
| due to bugs in header files of mingwrt 4.0.3 in strict ANSI mode, |
| cf. |
| |
| https://sourceforge.net/p/mingw/bugs/2024/ |
| https://sourceforge.net/p/mingw/bugs/2046/ |
| |
| * builds/unix/configure.raw: Don't set `-ansi' flag for MinGW. |
| |
| 2014-02-04 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Minor fix. |
| |
| * src/autofit/afcjk.c (af_cjk_metrics_init_widths), |

| |
| 2014-01-26 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Introduce two more slots for standard characters. |
| |
| This is useful for OpenType features like `c2sc' (caps to small |
| caps) that don't have lowercase letters by definition, or other |
| features that mainly operate on numerals. |
| |
| * src/autofit/afscript.h: Add more standard characters. |
| |
| * src/autofit/aftypes.h: Update use of `SCRIPT' macro. |

| |
| [autofit] Fix Indic scripts. |
| |
| Split the single, incorrect Indic entry into separate scripts so |
| that the covered ranges are the same: Bengali, Devanagari, Gujarati, |
| Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese, |
| Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove |
| entries for Meetai Mayak and Sharada – the Unicode ranges were |
| incorrect (and nobody has complained about that), fonts are scarce |
| for those scripts, and the Indic auto-hinter support is rudimentary |
| anyways. |
| |
| * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and |
| AF_CONFIG_OPTION_CJK. |
| |
| * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro. |
| Use it, together with AF_CONFIG_OPTION_INDIC and |
| AF_CONFIG_OPTION_CJK, to update. |
| |
| * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated. |
| [!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed. |
| Sort entries by tags. |
| |

| [autofit] Thinko. |
| |
| * src/autofit/hbshim.c (af_get_char_index): Similar to |
| `af_get_coverage', reject glyphs which are not substituted. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix handling of default coverages. |
| |
| With this commit, the implementation of coverage handling is |
| completed. |
| |
| * src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to |
| do. |
| Reject coverages which don't contain appropriate glyphs for blue |
| zones. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix handling of default coverages. |
| |
| * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): |

| default script, and finally the other default coverages. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix scaling of HarfBuzz shaping. |
| |
| * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Better ftgrid support. |
| |
| * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add |
| parameters `is_blue' and `blue_offset'. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Remove some styles. |
| |
| * src/autofit/afcover.h: Remove coverages for alternative fractions, |
| denominators, numerators, and fractions. |
| |
| * src/autofit/afstyles.h (META_STYLE_LATIN): Updated. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Add more styles. |
| |
| * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New |
| auxiliary macros; use them to define styles for Cyrillic, Greek, and |
| Latin. |
| |
| * src/autofit/afcover.h: Remove coverage for oldstyle figures. |
| Since those digits are used in combination with ordinary letters, it |
| makes no sense to handle them separately. |
| |
| * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit |
| `options' parameter to 4 bits. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix style assignments to glyphs. |
| |
| * src/autofit/hbshim.c (af_get_coverage) |
| [FT_CONFIG_OPTION_USE_HARFBUZZ]: Scan GPOS coverage of features also |
| so that we can skip glyphs that have both GSUB and GPOS data. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| * src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Implement and use `af_get_char_index' with HarfBuzz. |
| |
| * src/autofit/hbshim.c (COVERAGE) [FT_CONFIG_OPTION_USE_HARFBUZZ]: |
| Redefine to construct HarfBuzz features. |
| (af_get_char_index) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Rewritten. |
| |
| * src/autofit/aflatin.c (af_latin_metrics_init_blues): Use |

| |
| [autofit] Fix interface of `af_get_char_index'. |
| |
| * src/autofit/hbshim.c (af_get_char_index): Return error value. |
| Add argument for y offset (to be used in a yet-to-come patch). |
| |
| * src/autofit/hbshim.h, src/autofit/afcjk.c, |
| src/autofit/aflatin.c: Updated. |
| |
| 2013-12-30 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Don't combine multiple features into one set. |
| |
| Combining them, as originally envisioned, would lead to much more |
| complicated code, as investigations have shown meanwhile. The major |
| drawback is that we run out of available style slots much earlier. |
| However, this is only a theoretical issue since we don't support a |
| large number of scripts currently. |
| |
| * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with |
| a single-element `COVERAGE' macro, sort the elements by the feature |
| tags, and add entry for `ruby'. |
| |
| * src/autofit/aftypes.h: Updated. |
| * src/autofit/hbshim.c: Updated. |
| |
| 2013-12-28 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Code shuffling to reduce use of cpp macros. |
| |
| * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): |
| Call `af_get_coverage' unconditionally. |
| |
| * src/autofit/autofit.c: Include `hbshim.c' unconditionally. |
| |
| * src/autofit/hbshim.c (af_get_coverage) |
| [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Provide dummy function. |
| |
| * src/autofit/hbshim.h: Provide function declarations |
| unconditionally. |
| |
| 2013-12-28 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Add wrapper function for `FT_Get_Char_Index'. |
| |
| Yet-to-come changes will provide HarfBuzz functionality for the new |

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

| |
| [autofit] Introduce `coverages'. |
| |
| Coverages are the interface to the HarfBuzz library to acces |
| OpenType features for handling glyphs not addressable by the cmap. |
| |
| Right now, compilation of HarfBuzz is only added to the development |
| build. A solution for standard build mode will be delayed until |
| HarfBuzz gets split into two libraries to avoid mutual dependencies |
| between FreeType and HarfBuzz. |
| |
| Note that this is only a first step in handling coverages, basically |
| providing the framework only. Code for handling selected OpenType |
| features (this is, actually using the data in `afcover.h') will |
| follow. |
| |
| * devel/ftoption.h, include/config/ftoption.h |
| (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. |

| (AF_SCRIPT_FALLBACK): Renamed to ... |
| (AF_STYLE_FALLBACK): ... this. |

| Update use of `SCRIPT' and `STYLE' macros. |
| (af_face_globals_compute_style_coverage) |

| |
| Simplify header file hierarchy. |
| |
| This large patch changes the header file directory layout from |
| `include/freetype/...' to `include/...', effectively removing one |
| level. Since the file `ft2build.h' is also located in `include' |
| (and it stays there even after installation), all FreeType header |
| files are now in a single directory. |
| |
| Applications that use (a) `freetype-config' or FreeType's |
| `pkg-config' file to get the include directory for the compiler, and |
| (b) the documented way for header inclusion like |
| |
| #include <ft2build.h> |
| #include FT_FREETYPE_H |
| ... |
| |
| don't need any change to the source code. |

| [truetype] Minor code refactoring. |
| |
| Two benefits: The allocated FDEF (and IDEF) array gets slightly |
| smaller, and the `ttdebug' demo program has access to function |

| |
| Fortunately, no changes to FontForge are necessary – this is the |

| [arm] Fix thumb2 inline assembly under LLVM. |
| |
| When using `ADD' with an immediate operand, the instruction is |
| actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the |
| immediate operand cannot exceed 4095. It will fail to compile with |

| |
| However, in GCC, due to some legacy compatibility considerations, |
| `ADD.W' will be automatically emitted when the immediate operand is |

| |
| * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero. |
| |
| Note that the old code avoided using a region of the piecewise |

| different section of the function, which produced a different, |
| incorrect amount of darkening. |

| |
| * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount. |
| |
| This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect |
| is to use a previous darkening amount when producing an unhinted, |
| unscaled outline. This can cause autohint samples in ftgrid and |
| ftview to be based on darkened CFF outlines instead of unhinted, |
| undarkened ones. |
| |
| 2013-09-29 Dave Arnold <darnold@adobe.com> |
| |
| Fix Savannah bug #39295. |
| |
| The bug was caused by switching to the initial hintmap (the one in |
| effect when `moveto' executes) just before drawing the final element |
| in the charstring. This ensured that the path was closed (in both |
| Character Space and Device Space). But if the final element was a |
| curve and if the final hintmap was different enough from the initial |
| one, then the curve was visibly distorted. |
| |
| The first part of the fix is to draw the final curve using the final |
| hintmap as specified by the charstring. This corrects the |
| distortion but does not ensure closing in Device Space. It may |
| require the rasterizer to automatically generate an extra closing |
| line. Depending on the hintmap differences, this line could be from |
| zero to a couple pixels in length. |
| |
| The second part of the fix covers the case where the charstring |
| subpath is closed with an explicit line. We now modify that line's |
| end point to avoid the distortion. |
| |
| Some glyphs in the bug report font (TexGyreHeros-Regular) that show |
| the change are: |
| |
| 25ppem S (98) |
| 24ppem eight (52) |
| 25.5ppem p (85) |
| |
| Curves at the *end* of a subpath are no longer distorted. However, |
| some of these glyphs have bad hint substitutions in the middle of a |
| subpath, and these are not affected. |
| |
| The patch has been tested with a set of 106 fonts that shipped with |
| Adobe Creative Suite 4, together with 756 Open Source CFF fonts from |
| Google Fonts. There are 1.5 million glyphs, of which some 20k are |
| changed with the fix. A sampling of a few hundred of these changes |
| have been examined more closely, and the changes look good (or at |
| least acceptable). |
| |
| * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing' |
| to indicate that we synthesize a closepath line. |
| |
| * src/cff/cf2hints.c (cf2_glyphpath_init): Updated. |
| (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for |
| `lineto' operator) and adjust hint zone. |
| For synthesized closing lines, use end point in first hint zone. |
| (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In |
| particular, shift the detection of zero-length lines from character |
| space to device space. |
| (cf2_glyphpath_closeOpenPath): Remove assertion. |
| Updated. |

| Better tracing of loaded glyphs. |
| |
| Previously, the loading of a glyph was traced at level 4, if at all. |
| With this change, all font loading routines emit a tracing message |
| at level 1, making it easier to select tracing output (for example |
| using F2_DEBUG="any:1 afhints:7 aflatin:7"). |

| Change loops to use offsets (in file `afblue.h') into the new arrays |
| `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). |
| Instead of three dimensions (as used in the old blue string array) |
| we now use properties to do the same, saving one loop nesting level. |
| |
| * src/autofit/afcjk.h: Remove old enumeration values superseded by |
| the new data in `afblue.h'. |
| (AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE, |

| |
| 2013-08-25 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Introduce data file for blue strings. |
| |
| The idea is to have a central file which gets processed by a Perl |
| script to create proper `.c' and `.h' files using templates. There |
| are two other reasons to do that: |
| |
| . The data file should be easily readable. We use UTF-8 encoding |
| which then gets converted to single bytes. |
| |
| . Since the number of supported scripts will increase soon, the |
| current usage of blue string arrays is a waste of space. Using |
| the Perl script it is possible to imitate jagged arrays, |
| defining enumeration constants as offsets into the arrays. |
| |
| This commit only adds files without changing any functionality. |
| |
| * src/autofit/afblue.dat: New data file. |
| * src/tools/afblue.pl: New Perl script for processing `afblue.dat'. |
| |
| * src/autofit/afblue.cin, src/autofit/afblue.hin: New template files |

| [autofit] Improve handling of `near' points. |
| |
| Points which are very near to each other are now marked as such. |
| The `weak' flag is then computed by using the `in' vector of the |
| first and the `out' vector of the last point of a group of near |
| points. |
| |
| For example, this fixes the rendering of glyph `Oslash' in |
| `Roboto-Thin.ttf'. |
| |
| * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. |
| |
| * src/autofit/afhints.c (af_glyph_hints_reload): Introduce |
| the heuristic value `near_limit' to decide whether the current point |
| is near to the previous one, then set `AF_FLAG_NEAR' accordingly. |
| Store good `in' vector (of last non-near point) in |
| `last_good_in_{x,y}' and use it as an argument to |
| `ft_corner_is_flat' if necessary. |
| |

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

| |
| For example, the `latin' writing system (in file `aflatin.c') is |

| |
| Optimize FT_MulFix for x86_64 GCC builds. |
| |
| This patch provides an optimized `FT_MulFix' implementation for |
| x86_64 machines when FreeType is built with GCC, or compatible |
| compilers like Clang. |
| |
| Example: |
| bin/ftbench -p -t 5 -s 14 -f 0008 Arial.ttf |
| |
| Before: |

| Load 4.863 us/op |
| Load_Advances (Normal) 4.816 us/op |
| Load_Advances (Fast) 0.028 us/op |
| Render 2.753 us/op |

| Get_BBox 0.301 us/op |
| |
| * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h |
| (FT_MulFix_x86_64): New function. |
| |
| 2013-07-16 David Turner <digit@google.com> |
| |
| Speed up ARMv7 support. |
| |
| When building for ARMv7 with thumb2 instructions, the optimized |
| `FT_MulFix_arm' assembly routine was not being used. |
| |
| The reason for this is in the `ftconfig.h' header, namely: |
| |
| - The assembly routine uses the `smull' instruction which is not |
| available when generating Thumb-1 machine code. It is available |
| in Thumb-2 mode, though. |
| |
| - The header was written a long time ago before Thumb-2 became |
| widely popular (e.g. with Android). So it simply doesn't use the |
| assembly routine if the `__thumb__' built-in macro is defined. |
| |
| - When compiling in Thumb-2 mode, the compiler will define both |
| `__thumb__' and `__thumb2__'. |
| |
| By checking for `(__thumb2__ || !__thumb__)', we ensure that the |
| assembly routine is only avoided when generating Thumb-1 code. |
| |
| Given that this is performance-sensitive function, this improves |
| `ftbench' as follows on a Galaxy Nexus: |
| |
| Before (us/op) After (us/op) |
| |
| - loading Arial.ttf glyphs at 14 ppem [1] |
| |
| Load 34.285 33.098 |

| - same operation with the light auto-hinter [2] |
| |
| Load 31.317 29.590 |
| |
| - same operation without hinting [3] |
| |
| Load 6.143 5.376 |
| |
| - loading Arial.ttf advances at 14 ppem [4] |
| |
| Load_Advances (normal) 34.216 33.016 |

| |
| Add support for color embedded bitmaps (eg. color emoji). |
| |
| A new load flag, FT_LOAD_COLOR, makes FreeType load color |
| embedded-bitmaps, following this draft specification |
| |
| https://color-emoji.googlecode.com/git/specification/v1.html |
| |
| which defines two new SFNT tables, `CBDT' and `CBLC' (named and |
| modeled after `EBDT' and `EBLC', respectively). The color bitmaps |
| are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA |
| pre-multiplied sRGB images. If PNG support is available, PNG color |
| images as defined in the same proposed specification are supported |
| also. |
| |
| Note that color bitmaps are converted to grayscale if client didn't |
| ask for color. |
| |
| * builds/unix/configure.raw: Search for libpng. |
| Add `--without-png' option. |
