5a1b9d01	2020-08-16T09:06:59	[base] Allow renderers of different formats. * src/base/ftobjs.c (FT_Render_Glyph_Internal): Do not return if the glyph's slot format is `FT_GLYPH_FORMAT_BITMAP`. The forthcoming 'bsdf' renderer will require bitmaps for processing. * src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove renderer's glyph format check before adding and removing them. The 'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`.

2373074a	2020-12-23T22:02:48	* builds/windows/detect.mk (COPY): Make it work with `shell`. Without this patch, we get the error builds/toplevel.mk:127: *** missing separator. Stop. Reported by Anuj, with a solution from Alexei.
768022b9	2020-12-23T11:30:19	meson.build (ft2_defines): Fix builds on Windows.
0d5f1dd3	2020-12-18T22:10:30	[autofit] Fix double division in stem darkening. The old code used to divide the darkening amount by em_ratio twice, leading to unnecessarily bold stems on certain fonts with higher units per em (e.g. Inter). This patch fixes it. The return value of af_loader_compute_darkening was also changed to use 16.16 fixed point to get rid of a redundant truncation operation. This should slightly improve the precision, although it's still bottlenecked by the emboldening function, which uses 26.6 fixed point. * src/autofit/afloader.[ch] (af_loader_compute_darkening): Return FT_Fixed. (af_loader_embolden_glyph_in_slot): Revise calculations.

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.
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/.
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).
7d3ab6a7	2020-12-05T09:29:25	* builds/toplevel.mk (do-dist): Remove `submodules` directory.
a6adb256	2020-12-02T14:15:07	* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested).
74822f64	2020-12-02T08:32:37	[base] Don't close 'stderr' after logging. * src/base/ftdebug.c, builds/windows/ftdebug.c (ft_logging_deinit): Fix it.
c764686b	2020-12-02T08:00:41	* submodules/dlg: Updated to commit 9f0c8b22.

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.
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.

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.
2a46d1f0	2020-08-27T13:01:05	[base] Add public API to change log handling function. * include/freetype/ftlogging.h (FT_Custom_Log_Handler): New function typedef to store the custom callback logging function.

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.

(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.
6730854c	2020-08-25T23:16:27	* src/smooth/ftsmooth.c (ft_smooth_raster_overlap): Limit width. Segmentation fault reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=24729

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.

[autofit] Fix double division in stem darkening. The old code used to divide the darkening amount by em_ratio twice, leading to unnecessarily bold stems on certain fonts with higher units per em (e.g. Inter). This patch fixes it. The return value of af_loader_compute_darkening was also changed to use 16.16 fixed point to get rid of a redundant truncation operation. This should slightly improve the precision, although it's still bottlenecked by the emboldening function, which uses 26.6 fixed point. * src/autofit/afloader.[ch] (af_loader_compute_darkening): Return FT_Fixed. (af_loader_embolden_glyph_in_slot): Revise calculations.

[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.

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.
