Note that `get_min_distance_conic` comes with two implementations (using an analytical and an iterative method, to be controlled with the `USE_NEWTON_FOR_CONIC` macro). | |
|
c918b54f | 2020-08-18 10:28:16 | [sdf] Add function to resolve corner distances. * src/sdf/ftsdf.c (resolve_corner): New function. | |
|
5a1b9d01 | 2020-08-16 09:06:59 | [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.

|
cd6ff28a | 2020-08-16 17:09:22 | [sdf] Add files for new 'sdf' module. Here is a breakdown of what the files will contain. * src/sdf/ftsdfrend.c, src/sdf/ftsdfrend.h: The 'sdf' and 'bsdf' renderers. * src/sdf/ftsdf.c, src/sdf/ftsdf.h: The rasterizer for the 'sdf' renderer. * src/sdf/ftbsdf.c, src/sdf/ftbsdf.h: The rasterizer for the 'bsdf' renderer. * src/sdf/ftsdfcommon.h: Commmon properties and functions for both rasterizers. * src/sdf/ftsdferrs.h: Common error defines. * src/sdf/sdf.c: For building a single object of the entire module. | |

 |
768022b9 | 2020-12-23 11:30:19 | meson.build (ft2_defines): Fix builds on Windows. | |
 |
0d5f1dd3 | 2020-12-18 22:10:30 | [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. | |
 |
c948df52 | 2020-12-17 15:53:51 | * include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): New public macro. The driver name is needed for `FT_Property_Set' and `FT_Property_Get'. | |
 |
f6be9276 | 2020-12-16 06:03:10 | [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 | 2020-12-14 16:11:06 | [type42] Pacify static analysis tools (#59682). * src/type42/t42objs.c (T42_Size_Init, T42_GlyphSlot_Init): Avoid warnings about uninitialized variables. | |
|

|
015a9b8d | 2020-12-07 10:27:42 | */*: s/FT_LOGGING/FT_DEBUG_LOGGING/. | |
|
7d3ab6a7 | 2020-12-05 09:29:25 | * builds/toplevel.mk (do-dist): Remove `submodules` directory. | |
|
a6adb256 | 2020-12-02 14:15:07 | * 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 | 2020-12-02 08:32:37 | [base] Don't close 'stderr' after logging. * src/base/ftdebug.c, builds/windows/ftdebug.c (ft_logging_deinit): Fix it. | |
|
c764686b | 2020-12-02 08:00:41 | * submodules/dlg: Updated to commit 9f0c8b22. | |
|

|
f6b0fd7b | 2020-12-02 07:08:24 | 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 | 2020-12-01 23:07:21 | [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 | 2020-12-01 22:13:40 | [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 | 2020-12-01 15:43:11 | * src/type42/t42parse.c: Fix `-Wformat` warnings. | |
 |

Use `ft_strrchr` to check for final newline character. | |
|
ab0ea068 | 2020-08-28 11:28:17 | Update logging related documentation. * docs/DEBUG: Updates related to `FT_LOGGING`. * README.git: Updates related to logging. | |
|
6d9e6b21 | 2020-08-28 09:56:38 | * src/*: Fix `-Wformat` warnings. | |
|
2a5d8e8f | 2020-08-27 23:28:05 | [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. (PreprocessorDefinitions): Add `FT_LOGGING` 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. | |
|

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>. | |

3ce0df52 | 2020-09-22 20:05:37 | [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 | 2020-08-25 20:52:32 | 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 | |

66978a58 | 2020-05-17 18:45:41 | 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 | 2020-09-11 23:47:54 | [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. | |

0f35b042 | 2020-07-06 10:56:36 | [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++.

b0667d2d | 2020-07-02 11:20:10 | [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. | |

bd7251ac | 2020-07-02 10:24:20 | [build] Put integer type definitions into `integer-types.h'. 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. | |

3bb512bc | 2020-07-03 22:29:34 | [smooth] Introduce direct oversampling for overlaps. 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. | |

19d39f43 | 2020-07-03 09:17:22 | [smooth] Use direct rendering mode in Harmony. Instead of rendering 3 bitmaps side by side and reshuffling, we use direct rendering to deliver the bitmaps on each third byte. * src/smooth/ftsmooth.c (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with... (ft_smooth_lcd_spans): ... new span function. | |

2d67511a | 2020-07-03 09:02:09 | [smooth] Separate LCD paths from gray rendering. This makes `ft_smooth_render' a lot smaller and easier to follow. It also cleanly separates Harmony and ClearType-style LCD rendering algorithms. Now I only wish to move LCD filtering and geometry from FT_Library to FT_Renderer. * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here... (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here. [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's. | |
