This generalizes magic outline shifts that make Harmony LCD rendering work in terms of precise two-dimensional RGB subpixel positions. These coordinates are now set in time of the `smooth' module initialization and later used to shift a glyph outline for rendering.

This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS. There are still some issues with metrics; additionally, an API to fetch color layers is missing. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_OPTION_COLOR_LAYERS): New macro. * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec, FT_Colr_InternalRec): New structures.

AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them. Tested on Solaris 11.4 beta with compiler versions: Sun Studio 8 (Sun C 5.5) Sun Studio 10 (Sun C 5.7) Sun Studio 11 (Sun C 5.8) Sun Studio 12 (Sun C 5.9) Sun Studio 12.1 (Sun C 5.10) Oracle Solaris Studio 12.2 (Sun C 5.11) Oracle Solaris Studio 12.3 (Sun C 5.12) Oracle Solaris Studio 12.4 (Sun C 5.13) Oracle Developer Studio 12.5 (Sun C 5.14) Oracle Developer Studio 12.6 (Sun C 5.15) gcc 5.5.0 gcc 7.3.0 and verified the libfreetype.so.6 generated by each of those compilers exported the same set of symbols. * builds/unix/configure.raw: Implement it. 2018-05-08 Werner Lemberg <wl@gnu.org> [autofit] Avoid potential SEGV if running out of memory.

This brings up the minimum required CMake version to 2.8.12. The installation paths follow the GNU defaults now, e.g. installing on a 64 bit host will place binaries into the lib64/ folder on e.g. Fedora. Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC). CMake will no longer look for a C++ compiler. Library and .so version now match the Autotools build. Comments in the build file and informational messages now use platform agnostic example commands. ftoption.h and ftconfig.h are written directly without a redundant `-new' copy. External dependencies are expressed as option()s and will turn up as such in cmake-gui. Internal: Properties such as dependencies and include directories are now privately set on the freetype library instead of globally. The CPack definitions have been cleaned up, the `make dist' has been removed. Source packages generated with CPack don't contain Autotools files and aren't used by the maintainers anyway. On Windows, src/base/ftver.rc is compiled to decorate the library with version and copyright information. A pkg-config file is now generated and installed. 2018-04-09 Werner Lemberg <wl@gnu.org> [truetype] Integer overflow issues.

Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts.

Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it. 2017-10-20 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Improve complex rendering at high ppem. At large sizes almost but not exactly horizontal segments can quickly drain the rendering pool. This patch at least avoids filling the pool with trivial cells. Beyond this, we can only increase the pool size. Reported, analyzed, and tested by Colin Fahey. * src/smooth/ftgrays.c (gray_set_cell): Do not record trivial cells. 2017-10-20 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Improve tracing in FT_Load_Glyph, FT_*_Size. * src/base/ftobjs.c (FT_Load_Glyph): Tag tracing messages with function name, glyph index, and load flags.

Type 1 requires large integers to be followed by `div'; cf. `Adobe Type 1 Font Format', section 6.2. <op == 255>: Push Type 1 four-byte numbers as `Int' always. This is to ensure `div' and `callsubr' get values they can use. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Extend Adobe interpreter (hints). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode. Allow adding hints mid-charstring. <cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands for three normal stem hints. This requires some recalculation of stem positions. Correction for left sidebearing. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Extend Adobe interpreter (hsbw, sbw). * src/psaux/psintrp.c (cf2_doStems): `hsbw' or `sbw' must be the first operation in a Type 1 charstring.

We can use the `haveWidth' boolean already present, instead of implementing `parse_state'. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Add Type 1 operations to Adobe CFF interpreter. The following Type 1 specific ops have been added (copied from `t1decode'): closepath vstem3 hstem3 seac sbw callothersubr pop setcurrentpoint hsbw The following require a Type 1 mode, because of differences in specification: hstem vstem vmoveto callsubr div rmoveto hmoveto Numbers The subsequent commits will implement these changes and adapt accesses of data and objects to the new interpreter. NOTE: Will not compile in the meantime! * src/psaux/psintrp.c: Add opcodes to enum.

Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Add missing objects for Type 1 (1/2). Move `CF2_Font' instance to `PS_Decoder'.

If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it. 2017-09-18 Alexei Podtelezhnikov <apodtele@gmail.com> [build] Declutter Visual C++ 2010-2017 project. * build/windows/vc2010/freetype.vcxproj: Use MaxSpeed (/02) optimization for Release configuration throughout the project. ---------------------------------------------------------------------------- Copyright 2017-2018 by David Turner, Robert Wilhelm, and Werner Lemberg.
