f6be9276	2020-12-16T06:03:10	[truetype] Fix incremental metrics (#59503). * src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph): Previously, the code would populate the phantom points before calling the `get_glyph_metrics` callback. For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros). (tt_get_metrics_incr_overrides): Renamed to... (tt_get_metrics_incremental): ... this. Updated caller * include/freetype/ftincrem.h: Update the documentation to make it clearer that `get_glyph_metrics` is to retrieve metrics from a non-standard source, but not for the purpose of imposing custom metrics.

a3edbfa9	2020-12-14T16:11:06	[type42] Pacify static analysis tools (#59682). * src/type42/t42objs.c (T42_Size_Init, T42_GlyphSlot_Init): Avoid warnings about uninitialized variables.
bd6d8e42	2020-12-10T20:23:12	.mailmap: Add Priyesh.
505943a6	2020-12-07T17:08:37	* builds/unix/configure.raw: Don't set `FT_DEBUG_LOGGING`. All debug options are handled exclusively in `ftoption.h`.
272ae5ee	2020-12-07T10:29:24	* src/*: More fixes for using a '\n' in `FT_TRACE` and `FT_ERROR`.
015a9b8d	2020-12-07T10:27:42	/: s/FT_LOGGING/FT_DEBUG_LOGGING/.
9f94d853	2020-12-05T09:41:36	docs/CHANGES: Mention `FT_LOGGING`.

f6b0fd7b	2020-12-02T07:08:24	Improve setup for 'dlg' library. * autogen.sh (copy_submodule_file), builds/toplevel.mk: Redirect stderr to `/dev/null`. * builds/toplevel.mk: Move code block to handle 'dlg' stuff into `check_platform` conditional. Also fix wildcard expressions for guarding `git submodule` commands. Also make file copying work with non-Unix platforms (untested).
fcdab61e	2020-12-01T23:07:21	[build] Use gcc (and clang) in C99 mode. Other compilers are unchanged. * builds/compiler/gcc-dev.mk, builds/compiler/gcc.mk (ANSIFLAGS): s/-ansi/-std=c99/. * builds/freetype.mk (FT_CFLAGS): Remove `-std=c99`. * builds/unix/configure.raw: Handle C99. Remove no longer needed test for gcc 4.6 and earlier.

1c229af2	2020-12-01T22:13:40	[dlg] Fix compiler warnings. * src/dlg/dlgwrap.c: Duplicate some feature test macros from `dlg.c`, which must come first before loading standard headers. For example, `freetype.h` loads `stdio.h` if compiled in debug mode.
047f295f	2020-12-01T21:23:04	Typos.
76915880	2020-12-01T15:43:11	* src/type42/t42parse.c: Fix `-Wformat` warnings.
33bd25ca	2020-08-31T18:02:47	[builds/unix] Check for 'pthread' library. * builds/unix/ax_pthread.m4: New file, taken from 'autoconf-archive' git repository. * builds/unix/configure.raw: Check for 'pthread'; also check whether it works.
ce43d808	2020-12-01T12:20:43	[base] Implement vertical alignment of log printing. Based on a patch by Priyesh. * include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH): New macro. * src/base/ftdebug.c, builds/windows/ftdebug.c (ft_log_handler): Print logs after a fixed width to handle different lengths of `FT_COMPONENT` entries. Use `ft_strrchr` to check for final newline character.
ab0ea068	2020-08-28T11:28:17	Update logging related documentation. * docs/DEBUG: Updates related to `FT_LOGGING`. * README.git: Updates related to logging.
6d9e6b21	2020-08-28T09:56:38	* src/*: Fix `-Wformat` warnings.
2a5d8e8f	2020-08-27T23:28:05	[builds/windows] Changes to build 'dlg' with FreeType on Windows. We only support Visual C++ 2010 and newer. * builds/windows/vc2010/script.bat: New windows batch file to copy necessary 'dlg' files from `submodules/dlg` to `src/dlg`. This file is used as a pre-built event in Visual C++. * builds/windows/ftdebug.c: Synchronize with `src/base/ftdebug.c`. * builds/windows/vc2010/freetype.vcxproj.filters: Add `src/dlgwrap.c`. * builds/windows/vc2010/freetype.vcxproj (AdditionalIncludeDirectories): Add include files of dlg for 'Debug' and 'Debug Static' configurations on both 'x64' and 'win32' platforms.

Add `DLG_STATIC' for 'Debug' configuration on 'x64' and 'win32' platforms. (DisableLanguageExtensions): We need to disable the `/Za` option when building 'dlg' with FreeType as 'dlg' strictly follows the C99 standard. Visual C++ produces behaves unexpectedly when compiling a C99 file with `/Za` option enabled.

(FT_Done_FreeType) [FT_LOGGING]: Call `ft_logging_deinit`. * src/base/ftobjs.c (FT_New_Library): Call `ft_debug_init` only if `FT_LOGGING` is not defined.
34b1c897	2020-08-26T12:27:52	[builds] Necessary changes to make 'dlg' compile. * autogen.sh (copy_submodule_files): New script to copy all the necessary source and include files from `submodules/dlg` to `src/dlg`. * src/dlg/dlgwrap.c: New wrapper file for `src/dlg.c`. It enables the build of 'dlg' if the `FT_LOGGING` macro is defined. * src/dlg/rules.mk: New sub-Makefile. * builds/freetype.mk (DLG_DIR): New variable to include the header files of the 'dlg' library. (INCLUDES): Add `DLG_DIR`. (FT_CFLAGS): Add `-std=c99' flag. Include `src/dlg/rules.mk` file to build 'dlg' library. (OBJ_S, OBJ_M): Add `DLG_OBJS_M` and `DLG_OBJS_S`. * builds/toplevel.mk: For builds directly from the git repository we need to copy files from `submodule/dlg` to `src/dlg`. * include/freetype/config/ftoption.h, devel/ftoption.h (FT_LOGGING): New macro to enable or disable the logging facility in FreeType.

c9f588be	2020-10-10T12:48:18	Document changes to last release.
40479fad	2020-09-25T17:44:00	[autofit] Synchronize with ttfautohint. 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.
e8ee98e6	2020-09-25T07:22:08	Move `scripts/make_distribution_archives.py` to `src/tools`. * 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.
4f13a43a	2020-09-24T09:35:24	* src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`. 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>.
bed960d9	2020-09-24T09:31:56	* src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics.
3ce0df52	2020-09-22T20:05:37	[meson] Move auxiliary scripts to `builds/meson`. Suggested by Alexei. * scripts/.py: Move meson scripts to... builds/meson/.py: ... this new location. meson.build: Updated.
d686f2ff	2020-08-25T20:52:32	Add python script for building tarballs. * 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
46417607	2020-09-21T09:03:13	* scripts/extract_freetype_version.py: Fix regex typos.
66978a58	2020-05-17T18:45:41	Add Meson build project file. 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).

20186d1b	2020-09-11T23:47:54	[raster] Improve the second pass (#58373). 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.
c3721642	2020-09-11T23:13:02	[raster] Tune SMART macro (#58352). 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.
cb473313	2020-09-08T22:41:53	[raster] Introduce SMART macro. * src/raster/ftraster.c (SMART): New macro for smart dropout rounding. (Verstical_Sweep_Drop, Horizontal_Sweep_Drop): Use it.
3594eaee	2020-09-08T22:20:11	[raster] Improve tracing.

600d59e3	2020-09-02T15:48:03	[truetype] Reduce Infinality footprint (cont'd). * src/truetype/ttinterp.c (Ins_DELTAP): Shrink variable scope. (Ins_SHPIX, Ins_MIRP): Revise if-logic.
51a5e338	2020-09-02T00:02:28	[truetype] Reduce Infinality footprint. * src/truetype/ttinterp.c (Ins_SHPIX, Ins_MSIRP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Shrink variable scopes and consolidate ifdefs.
e6c7e4b4	2020-09-01T21:49:52	[truetype] Refactor compensation color. * src/truetype/ttinterp.h (TT_Round_Func): Change the last argument. * src/truetype/ttinterp.c (Ins_ROUND, Ins_NROUND, Ins_MDAP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Move compensation retrieval from here... (Round_): ... to here. src/truetype/ttobjs.c (tt_size_init_bytecode): Reserve zero compensation at color index 3.
16ee2a22	2020-08-28T23:08:42	[smooth] Don't set target in direct mode. * src/smooth/ftsmooth.c (ft_smooth_raster_overlap): Remove assignment. (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Ditto.
d8228a00	2020-08-28T22:28:47	Improve FT_Outline_Render docs.

cdc009c2	2020-08-22T13:30:11	* src/truetype/ttgload.c (TT_Get_VMetrics): Add tracing message.
f9f6adb6	2020-08-05T08:24:15	[truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND. 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. (load_truetype_glyph): Retain OVERLAP_COMPOUND.
3a1f4b7a	2020-08-04T22:17:05	* src/truetype/ttgload.c (TT_Load_Glyph): More tracing.
8b360132	2020-08-04T10:48:42	Minor typos, formatting.

ee19a6cb	2020-05-01T15:37:56	Add .clang-format file 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)

0f35b042	2020-07-06T10:56:36	[build] Really fix multi and C++ builds. 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'.
cb4a943b	2020-07-06T10:56:36	[build] Fix multi and C++ builds. 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'.

b0667d2d	2020-07-02T11:20:10	[build] Improve visibility support of library function names. * 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.
bb66c8d8	2020-07-02T11:09:57	[build] Split off more stuff from `ftconfig.h'. * 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.

[truetype] Fix incremental metrics (#59503). * src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph): Previously, the code would populate the phantom points before calling the `get_glyph_metrics` callback. For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros). (tt_get_metrics_incr_overrides): Renamed to... (tt_get_metrics_incremental): ... this. Updated caller * include/freetype/ftincrem.h: Update the documentation to make it clearer that `get_glyph_metrics` is to retrieve metrics from a non-standard source, but *not* for the purpose of imposing custom metrics.

Move `scripts/make_distribution_archives.py` to `src/tools`. * 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`. 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>.

Add python script for building tarballs. * 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

Add Meson build project file. 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). 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.

Add .clang-format file 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)

[build] Really fix multi and C++ builds. 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++.
