Werner Lemberg 92bd99bd 2021-02-16T14:07:18 Move 'dlg' submodule to `subprojects` directory. This is for future changes with Meson, which doesn't allow a different name for its `subprojects` directory. Having both a `submodules` and a `subprojects` directory is confusing. * .gitmodules, autogen.sh (copy_submodule_files, DLG_INC_DIR, DLG_SRC_DIR): Updated. * builds/toplevel.mk (<top-level>, do-dist), builds/windows/vc2010/script.bat: Updated. * src/tools/no-copyright: Updated.
Dominik Röttsches 215ae253 2021-02-16T12:53:45 [sfnt] Update paint format values to support non-variable paints. * freetype.h (FT_PaintFormat): Update paint format identifiers after a specification change. The specification was updated to have sibling formats, variable and non-variable variants for each. Reflect that here. * sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as the non-variable formats no longer have them.
Daniel E b2aeca5f 2021-02-14T20:25:21 * CMakeLists.txt: Improve 'bz2' support. Not all distributions such as FreeBSD provide a `.pc` file for '(lib)bz2' so follow autotools and add it to `Libs.private` instead.
Werner Lemberg 7849316c 2021-02-13T09:21:37 * src/tools/update-copyright-year: Fix single-year entry handling. The fix from 2021-01-17 didn't cover the case where the year to be updated is identical to the current year.
Werner Lemberg d51452e3 2021-02-13T08:52:58 Add new function `FT_Get_Transform`. See https://github.com/harfbuzz/harfbuzz/issues/2428 for some reasons to introduce this function. * include/freetype/freetype.h, src/base/ftobjs.c (FT_Get_Transform): Implement it.
Werner Lemberg d93a0119 2021-02-13T07:50:04 Minor editing of last commit; formatting.
Alexei Podtelezhnikov 70fd20e6 2021-02-12T19:28:05 Decorate qsort callbacks with cdecl. * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF): Add new macro. * src/base/ftrfork.c, src/bdf/bdflib.c, src/gxvalid/gxvcommn.c, src/psaux/afmparse.c, src/psnames/psmodule.c, src/type1/t1afm.c, src/sfnt/sfwoff.c, src/sfnt/sfwoff2.c: Update qsort callbacks. Fixes #1026 when compiling FreeType with an unusual calling convention while the C library qsort still expects cdecl.
Dominik Röttsches 54c5ad5c 2021-02-10T19:24:13 [sfnt] Implement 'COLR' v1 sweep gradients. * freetype.h (FT_PaintSweepGradient): Add `FT_PaintSweepGradient` to represent a 'COLR' v1 sweep gradient. Update format. (FT_PaintFormat): Update shifted paint formats. Sync with spec. * sfnt/ttcolr.c (read_paint): Logic to parse sweep gradients. Fix struct access in radial gradient implementation.
Werner Lemberg c8dede7b 2021-02-10T18:58:21 [dlg] Update submodule to upstream's current master.
Dominik Röttsches 64f01bfe 2021-01-20T13:04:50 [sfnt] Provide optional root transform for 'COLR' v1 glyph graph. * include/freetype/freetype.h (FT_Get_Color_Glyph_Paint): Additional function argument root_transform to control whether root transform should be returned. (FT_OpaquePaint): Additional tracking field to denote whether root transform is to be returned. * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_Paint_Func): Propagate additional argument. * src/base/ftobjs.c (FT_Get_Color_Glyph_Paint): Ditto. * src/sfnt/ttcolr.c (tt_face_get_colr_glyph_paint): Return root transform reflecting the size and tranform configured on FT_Face. (read_paint): Initialize and track status of insert_root_transform flag.
Xavier Claessens cc90307d 2021-02-10T09:30:40 * meson.build: s/freetype2_dep/freetype_dep/. Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep` variable name to use FreeType as subproject because that was the variable name in Centricular's Meson port of FreeType. While they should stop hardcoding that variable name, it does not cost us anything to keep using that name to ease transition.
Xavier Claessens 3dbdb78a 2021-02-10T09:25:42 [meson] Fix handling of HarfBuzz library. * meson.build (harfbuzz_dep): Do not fall back to HarfBuzz by default. Otherwise it causes a dependency cycle: cairo => fontconfig => freetype2 => harfbuzz => cairo Meson will still fall back to HarfBuzz subprojects if the `harfbuzz` option is set to `enabled` instead of `auto` and a `subprojects/harfbuzz.wrap` file is present. In that case it is the responsibility of the main project to set the proper options on each subproject to break the dependency cycle. Fixes: #1028.
Xavier Claessens 0565c5ba 2020-10-26T11:31:19 * meson.build: Use `meson.override_dependency`. This is a new meson mechanism to avoid other projects to hard-code the `freetype2_dep` variable name in their build definition. It also ensures that meson does not mix system and subproject versions of FreeType inside of the same project. Also remove outdated TODO because `declare_dependency` was already there.
Xavier Claessens 2c405596 2020-10-26T14:56:05 Meson: Fix dependency lookup and generate ftconfig.h [meson] Fix dependency lookup and generate `ftconfig.h`. - zlib: If not found on the system, meson can build it as a subproject. We thus never use the (outdated) zlib support that comes with FreeType. Doing so has the additional advantage that the zlib code can be shared with other projects like GLib if both are subprojects of an application. - harfbuzz: Build as a subproject if not found on the system. - 'QUESTION: What if the compiler doesn't support `-D` but uses `/D` instead as on Windows?' Answer: Meson translate arguments for us. - visibility: Replace self-made code with meson-specific solution. * meson.build (ft2_defines): Rewrite logic to set and handle it. (process_header_command): New variable, previously called `ftoption_command`. (ftoption_command, ftconfig_command): New variables. (zlib_option): Removed. (zlib_dep): New variable. (ft2_deps): Updated. (harfbuzz_dep): Updated. (ftconfig_h_in, ftconfig_h): New variables. (ft2_sources): Updated. (ft2_lib): Updated, handle visibility. (summary): Updted. * meson_options.txt (zlib): Updated.
Xavier Claessens e11cc40a 2020-10-26T14:21:19 * meson.build: Fix resource compilation on Windows. This is copied from GStreamer's meson port of FreeType. (ft2_sources): Add both debug and resource file (the latter for Windows only). (ft2_debug_src): Removed.
Xavier Claessens 69e0faa8 2020-10-26T13:39:19 * meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/. (freetype2_dep): Use it. `ft2_libtool_version` would be the shared library version, not the one we should use in file `freetype2.pc`.
Xavier Claessens 5c81e09b 2020-10-26T11:26:04 * meson.build (bzip2_dep): Simplify. We remove `static:false` from `find_library('bz2')`. I don't know whether the previous code was a workaround for an old meson bug, but at least with version >=0.55.0 (which FreeType uses) it picks the shared library when both are available. With this commit, file `freetype2.pc` no longer contains the full path to file `libbz2.so`; instead, it correctly uses `-lbz2`. Note that this is a meson bug is still present in the current version (0.57.0).
Xavier Claessens 1b69fb9b 2020-10-26T11:25:08 * meson.build: Set project version.
Werner Lemberg 947e4752 2021-02-04T10:19:26 [base] Fix Netpbm tracing message. * src/base/ftobjs.c (FT_Render_Glyph_Internal): Don't emit Netpbm warning if there is nothing to output.
Werner Lemberg d924a66a 2021-02-04T07:44:06 * 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). This is a continuation of a similar patch from 2020-12-02, which missed some locations.

Werner Lemberg 324612ce 2021-01-31T14:28:44 Always provide logging API. It's easier to have stubs if FT_DEBUG_LOGGING is undefined than to modify `ftexport.sym` conditionally. Problem reported by Alexei. * src/base/ftdebug.c: Include `ftlogging.h`. (FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler, FT_Set_Default_Log_Handler) [!FT_DEBUG_LOGGING]: Provide stubs.
Werner Lemberg 939e8444 2021-01-30T06:32:38 * builds/unix/configure.raw: Fix typo. Bug introduced in Vincent's last commit bb33f03. Fixes issue #1021.
Alexei Podtelezhnikov 7ae5609d 2021-01-27T16:08:08 * src/base/ftstroke.c (FT_Stroker_EndSubPath): Ignore tiny gaps. Fixes bug #1020.
Alexei Podtelezhnikov 4c3bd2ab 2021-01-27T15:54:34 [stroker] Minor clean-up. * src/base/ftstroke.c (FT_Stroker_{ConicTo,CubicTo}): Reset the last line length. (FT_Stroker_EndSubPath): Call `ft_stroker_process_corner'.

Dominik Röttsches 268bdd77 2021-01-15T14:49:32 CHANGES: Mention 'COLR' v1 support.
Werner Lemberg ba1a6acf 2021-01-15T10:09:00 [sfnt] Additional checks for 'colr' table presence. * sfnt/ttcolr.c (tt_face_get_colr_glyph_paint, tt_face_get_colorline_stops, tt_face_get_paint): Additional checks for whether colr table is present. Prevents crashes when these methods are called on non-COLR fonts.
Dominik Röttsches 53fea877 2021-01-14T16:06:03 Add config option to test for 'COLR' v1 support in headers. * include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro so that clients can test whether the FreeType checkout that they are building against supports the 'COLR' v1 API. This is intended to be a temporary solution until 'COLR' v1 support is released in a FreeType version and such a check can be made by using the version number instead.
Dominik Röttsches 4b58cf47 2020-12-16T17:18:56 [base] Fill 'COLR' v1 API templates to make them work (#59703). * src/base/ftobjs.c (FT_Get_Color_Glyph_Paint, FT_Get_Paint_Layers, FT_Get_Paint, FT_Get_Colorline_Stops): Add basic sanity checks, check for existence of `FT_Face`, check arguments and delegate calls for the respective 'COLR' v1 API to the SFNT driver.

Dominik Röttsches be06a9d0 2020-12-16T17:02:22 [sfnt] Add 'COLR' v1 API to iterate color stops (#59703). * src/sfnt/ttcolr.c (tt_face_get_colorline_stops): New function to return the current `FT_ColorStop` object from `FT_ColorStopIterator`. Also increment the iterator. * src/sfnt/ttcolr.h: Updated.
Dominik Röttsches cdad4db4 2020-12-16T16:52:24 [sfnt] Add API to get actual paint from `FT_OpaquePaint` (#59703). * src/sfnt/ttcolr.c (tt_face_get_paint): New function to resolve an `FT_OpaquePaint` paint reference into an `FT_COLR_Paint` object of a certain format, which contains the detailed information stored in a paint of the respective format. (read_paint): New function to provide the format specific parsing and to populate the data members of each specific `FT_COLR_Paint` subtype. (read_color_line): New function to parse retrieved color line information into an `FT_ColorLine` object, which has information about the color line extend mode as well as an `FT_ColorStopIterator` object. * src/sfnt/ttcolr.h: Updated.
Dominik Röttsches 9e422b67 2020-12-16T16:44:34 [sfnt] Add API to retrieve 'COLR' v1 root paint (#59703). * src/sfnt/ttcolr.c (BaseGlyphV1Record): New structure. (tt_face_load_colr): Handle version 1 table header. (find_base_glyph_v1_record): New auxiliary function. (tt_face_get_colr_glyph_paint): New function to find the root `FT_OpaquePaint` object for a given glyph ID. * src/sfnt/ttcolr.h: Updated.
Dominik Röttsches 08dba4dc 2020-12-16T16:14:19 Add new methods required for 'COLR' v1 to public API (#59703). * include/freetype/freetype.h (FT_Get_Color_Glyph_Paint): New method for retrieving the root paint object for a color glyph by specifying a glyph ID. (FT_Get_Paint_Layers): New method for retrieving the layers of a `PaintColorGlyph`. (FT_Get_ColorLine_Stops): New method for retrieving the stops of a color. (FT_Get_Paint): New method for resolving an `FT_OpaquePaint` into an `FT_COLR_Paint` object.
Dominik Röttsches f57c24db 2020-12-16T16:02:02 Add types required for 'COLR' v1 to public API (#59703). * include/freetype/freetype.h (FT_PaintFormat, FT_ColorStopIterator, FT_ColorIndex, FT_ColorStop, FT_PaintExtend, FT_ColorLine, FT_Affine23, FT_CompositeMode, FT_OpaquePaint, FT_PaintColrLayers, FT_PaintSolid, FT_PaintLinearGradient, FT_PaintRadialGradient, FT_PaintGlyph, FT_PaintColrGlyph, FT_PaintTransformed, FT_PaintTranslate, FT_PaintRotate, FT_PaintSkew, FT_PaintComposite, FT_COLR_Paint): Adding structs and enum to represent paint format, color stop information, gradient extend information, structs to reference paint offsets, and to define transforms and compositions. Adding a union type to represent the union of the structs, distinguished by `FT_PaintFormat`.

Anuj Verma 05f6088d 2020-08-20T07:54:13 [sdf] Added basic overlapping contour support. * src/sdf/ftsdf.c (sdf_generate_with_overlaps): New function. (sdf_raster_render): Enable it.
Anuj Verma 879ca87f 2020-08-19T16:57:38 [sdf] Add build infrastructure. * src/sdf/module.mk, src/sfd/rules.mk: New files. * src/sdf/ftsdf.h (ft_sdf_raster): New forward declaration. * include/freetype/ftmoderr.h (FT_MODERRDEF): Add error definition for the 'sdf' module. * include/freetype/internal/fttrace.h (FT_TRACE_DEF): Add trace definition for the `sdf' module. * modules.cfg (RASTER_MODULES): Add the `sdf' module to the list of rasterizers.
Anuj Verma 665ac967 2020-08-19T16:29:51 [sdf] Add interface functions for the 'sdf' rasterizer. * src/sdf/ftsdf.c (sdf_raster_new, sdf_raster_reset, sdf_raster_set_mode, sdf_raster_render, sdf_raster_done): New functions. (ft_sdf_raster): New structure.
Anuj Verma 1010f2c3 2020-08-19T16:25:08 [sdf] Add subdivision and bounding box optimization. * src/sdf/ftsdf.c (sdf_generate_bounding_box): New function, which is an optimized version of `sdf_generate`. (sdf_generate_subdivision): New function.
Anuj Verma 986d3108 2020-08-19T12:56:58 [sdf] Add function to generate SDF. * src/sdf/ftsdf.c (sdf_generate): New function, currently disabled. This is a proof-of-concept implementation: It doesn't use any optimization, it simply checks all grid points against all contours.
Anuj Verma 0d52f4ae 2020-08-19T12:22:34 [sdf] Add functions to get shortest distance from any edge/contour. * src/sdf/ftsdf.c (sdf_edge_get_min_distance): New function. (sdf_contour_get_min_distance): New function, currently disabled.
