* [autofit] Synchronize with ttfautohint.Werner Lemberg2020-09-258-114/+214
| | | | | | | | | | | | | | | | This corresponds to the following commits in the ttfautohint git repository: bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting. d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa Add Medefaidrin script. * src/autofit/afblue.dat: Add blue zone data for Medefaidrin. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Medefaidrin standard characters. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin data.
* Move `scripts/make_distribution_archives.py` to `src/tools`.Werner Lemberg2020-09-252-5/+17
| | | | | | | | | | * scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR, _SCRIPT_DIR): Updated to new location. (main): s/shutils.copyfile/shutils.copy/ to preserve file permissions. (main): Prefix source file paths with `git_dir` while copying files to allow calls of the script from other places than the top-level directory.
* * src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`.Werner Lemberg2020-09-242-4/+17
| | | | | | | | | Towards the end of the the function there is a call to `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` is left alone, and is not scaled. Patch from Eric Muller <emuller@amazon.com>.
* * src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics.Werner Lemberg2020-09-242-0/+23

* [meson] Move auxiliary scripts to `builds/meson`.Werner Lemberg2020-09-227-8/+19
| | | | | | | | | Suggested by Alexei. * scripts/*.py: Move meson scripts to... * builds/meson/*.py: ... this new location. * meson.build: Updated.
* Add python script for building tarballs.David Turner2020-09-212-0/+240
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * scripts/make_distribution_archives.py: New file. This standalone Python script should be equivalent to running `make dist` with the Make-based build system, with the following minor differences: - Since `make distclean` doesn't always clean up `objs/` properly, `make dist` archives may contain some stale binaries like `objs/.libs/libfreetype.so.6` or others. - `config.guess` and `config.sub` are not updated unless option `--gnu-config-dir=DIR` is used to specify the location of these files. - Some bits of the auto-generated reference documentation may appear in slightly different order, probably due to issues related to mkdocs and docwriter. As an example, the call scripts/make_distribution_archives.py /tmp/freetype2-dist creates the following files under `/tmp/freetype2-dist`: freetype-<version>.tar.gz freetype-<version>.tar.xz ft<winversion>.zip
* * scripts/extract_freetype_version.py: Fix regex typos.Werner Lemberg2020-09-212-3/+7

* Add Meson build project file.David Turner2020-09-219-1/+1038
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Example usage: # Configure Meson build in directory `build-meson` to generate # release binaries comparable to to the ones from the # autotools/make build system. meson setup build-meson \ --prefix=/usr/local \ --buildtype=debugoptimized \ --strip \ -Db_ndebug=true # After configuring the Meson build with the above command, # compile and install to `/usr/local/`; this includes a pkg-config # file. ninja -C build-meson install # Alternatively, compile and install to `/tmp/aa/usr/local/...` # for packaging. DESTDIR=/tmp/aa ninja -C build-meson install # Generate documentation under `build-meson/docs`. ninja -C build-meson docs Library size comparison for stripped `libfreetype.so` generated by all three build systems: - Default build (autotools + libtool): 712 KiB - CMake build (RelWithDebInfo): 712 KiB - Meson build: 712 KiB * meson.build: New top-level Meson build file for the library. * meson_options.txt: New file. It holds user-selectable options for the build, which can be printed with `meson configure`, and selected at `meson setup` or `meson --reconfigure` time with `-D<option>=<value>`. * scripts/parse_modules_cfg.py: A script invoked by `meson.build` to parse `modules.cfg` and extract important information out of it (i.e., the list of modules). * scripts/process_ftoption_h.py: New script invoked by `meson.build` to process the original `ftoption.h` file. It enables or disables configuration macro variables based on the available dependencies. This is similar to what other build systems are using (i.e., Meson's `configure_file()` command is not used here). * scripts/extract_freetype_version.py: New script invoked by `meson.build` to extract the FreeType version number from `<freetype/freetype.h>`. * scripts/extract_libtool_version.py: New script invoked by `meson.build` to extract the libtool `revision_info` data from `builds/unix/configure.raw`, and to generate the corresponding shared library suffix. * scripts/generate_reference_docs.py: New script invoked by `meson.build` to generate the FreeType 2 reference documentation (using the `docwriter` and `mkdocs` packages, which must be already installed).

* [raster] Improve the second pass (#58373).Alexei Podtelezhnikov2020-09-112-23/+58
| | | | | | | | | | Besides dropout control the second horizontal sweep is supposed to clean up straight horizontal edges that are mishandled by the first vertical sweep when a line passes through pixel centers. This line would present as perfectly aligned span edges in the second sweep. * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old implementation with a better one focusing on aligned span edges only.
* [raster] Tune SMART macro (#58352).Alexei Podtelezhnikov2020-09-112-2/+13
| | | | | | | | Windows seems to perform smart dropout control at 26.6 precision. To mimick Windows independent of increased precision, we need to tweak the macro so that some close calls break down rather than up. * src/raster/ftraster.c (SMART): Tweak the macro.
* [raster] Introduce SMART macro.Alexei Podtelezhnikov2020-09-082-4/+14
| | | | | * src/raster/ftraster.c (SMART): New macro for smart dropout rounding. (Verstical_Sweep_Drop, Horizontal_Sweep_Drop): Use it.

* [truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND.Alexei Podtelezhnikov2020-08-054-4/+29
| | | | | | | | | | | | | For glyphs with OVERLAP_SIMPLE or OVERLAP_COMPOUND, set FT_OUTLINE_OVERLAP to render them with direct oversampling, which mitigates artifacts (see 3bb512bc9f62). * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): Redefine to rhyme with OVERLAP_SIMPLE. * src/base/ftgloadr.c (FT_GlyphLoader_Rewind): Reset outline flags. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Retain OVERLAP_SIMPLE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This file can be used to reformat FreeType sources and commits using one of these methods: - Direct formatting of a whole file: clang-format -i path/to/file For example, to reformat all sources at once: echo builds/unix/ftconfig.h.in $(git ls-files *.[hc]) | xargs clang-format -i - Only reformat the changed lines in the current work directoy: git clang-format The style settings in this file are very close to the FreeType formatting style, with the following exceptions which are not supported here: - Mminimal 2-space margin on each non-empty line. (no left margin instead). - 2 empty lines between variable declarations and statements in C blocks. (only 1 is kept). { int x = ...; foo(x); } becomes { int x = ...; foo(x); } - Aignment of declarations uses 2 spaces to separate types and variable names (only 1 space is kept). int x; => int x; int y; int y; - The start used for output parameters in function signature should be near the variable name (always near the type). void foo(int* input_ptr, int *output_ptr) => void foo(int* input_ptr, int* output_ptr)

* Document `FT_Face_Rec_::box' with variable fonts (#54969).Ben Wagner2020-07-101-0/+3
| | | | | | | | | | | | | As pointed out in the "Note:" in the section of https://docs.microsoft.com/en-us/typography/opentype/spec/otvaroverview#variation-data-tables-and-miscellaneous-requirements ... the xMin, yMin, xMax, yMax, macStyle and lowestRecPPEM fields in the font header ('head') table are not supported by variation data and should only be used in relation to the default instance for the font. Document that `FT_Face_Rec_::box' does not vary with OpenType variable fonts.

* [build] Really fix multi and C++ builds.David Turner2020-07-077-18/+58
| | | | | | | | | | | | | | | | | | | | | | | | The following builds were still failing due to previous changes: make multi make multi CC="c++" make CC="c++" This patch fixes the issues, which were missing includes to get the right macro definitions in multi-build mode. Also, `FT_UNUSED' is actually used by third-party code, so move it back to `public-macros.h' to avoid breaking it. * include/freetype/config/public-macros.h (FT_EXPORT): Remove special definition for C++. (FT_UNUSED): Define here instead of... * include/freetype/config/compiler-macros.h: ... here. (FT_FUNCTION_DECLARATION): Remove special definition for C++. (FT_LOCAL_ARRAY_DEF): Fix definition. * src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h, src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.
* [build] Fix multi and C++ builds.David Turner2020-07-0611-15/+40
| | | | | | | | | | | | | | | | | | The following builds were failing due to previous changes: make multi make multi CC="c++" * include/freetype/config/ftconfig.h: Remove `FT_END_HEADER'. * include/freetype/config/ftheader.h (FT_BEGIN_HEADER, FT_END_HEADER): Protect against redefinition. * src/cache/ftccache.h, src/cache/ftcmru.h, src/pcf/pcfutil.h, src/psaux/pserror.h, src/psaux/psft.h, src/psaux/psstack.h, src/sfnt/woff2tags.h: Include `compiler-macros.h'. * src/sfnt/woff2tags.c: Include `woff2tags.h'.
* [psaux] Improve `t1_decoder_parse_metrics' (#58646).Werner Lemberg2020-07-062-11/+116
| | | | | | * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function to handle `op_callsubr' and `op_return'.
* [build] Improve visibility support of library function names.David Turner2020-07-053-120/+178
| | | | | | | | | | | | | | | | | | | | | * include/freetype/config/public-macros.h (FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as public (and thus exportable). (FT_EXPORT): Use it. * include/freetype/config/compiler-macros.h (FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as internal to the library (and thus hidden). Note that on ELF systems, all internal functions have hidden visibility, which avoids the need to enforce this when invoking the compiler (e.g., with an option like `-fvisibility=hidden'). (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros to deal with C and C++ linkage issues at the same time. (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF, FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK, FT_BASE_CALLBACK_DEF): Redefined using new macros.
* [build] Split off more stuff from `ftconfig.h'.David Turner2020-07-0514-808/+369
| | | | | | | | | | | | | | | * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions required by the FreeType API headers to... * include/freetype/config/public-macros.h: ...this new file. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions used by the library but not to be exposed to clients to... * include/freetype/config/compiler-macros.h: ...this new file. * include/freetype/internal/*.h, src/raster/ftraster.h: Include `compiler-macros.h' where needed.
* [build] Move mac support code to `mac-support.h'.David Turner2020-07-057-111/+66
| | | | | | | | | | | * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off mac-specific stuff to... * include/freetype/config/mac-support.h: ...this new file. * CMakeLists.txt, builds/unix/configure.raw: Remove `/undef -> #undef' string replacement; the affected code is no longer part of the `ftconfig.h' template.
* [build] Put integer type definitions into `integer-types.h'.David Turner2020-07-056-685/+292
| | | | | | | | | | | | | | | | | | | | | Refactor some of the `ftconfig.h' headers and template to move the definition of the FreeType integer types (e.g., `FT_Int16') to a common header file `freetype/config/integer-types.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off integer type definition stuff to... * include/freetype/config/integer-types.h: ...this new file. * builds/unix/ftconfig.h.in: Control the definition of `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto detection happens in `integer-types.h' as usual based on `INTXX_MAX' values. Otherwise the autoconf-detected values are used. * builds/unix/configure.raw (CPPFLAGS): Don't include path to `config' directory. Instead, ... (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.
* [build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'.David Turner2020-07-054-8/+18
| | | | | | | | | | Since we are no longer limited to 8.3 file names, it is simpler to follow the usual conventions for template files. * builds/unix/ftconfig.in: Renamed to... * builds/unix/ftconfig.h.in: ...this. * CMakeLists.txt, builds/unix/configure.raw: Updated.
* [smooth] Introduce direct oversampling for overlaps.Alexei Podtelezhnikov2020-07-033-6/+121
| | | | | | | | | | | | | This implements oversampling to metigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... (ft_smooth_raster_overlap): ... inflate outline and set up direct rendering for oversampling with... (ft_smooth_overlap_spans): ... new span function that integrates them.
