Dominik Röttsches 47cf8ebf 2021-07-28T17:36:57 [sfnt] Add API for retrieving a 'COLR' v1 'ClipBox' table. The optional 'COLR' v1 glyph-specific clip box helps upstream graphics libraries allocate a sufficiently large bitmap for a glyph without having to traverse the glyph graph for that. See https://github.com/googlefonts/colr-gradients-spec/issues/251 for background on the introduction of this specification change. * include/freetype/ftcolor.h (FT_ClipBox): New structure.

Alex Richardson f7c6a06c 2021-07-12T13:58:10 Support architectures where `long` is smaller than pointers. I am currently trying to compile FreeType for CHERI-extended ISAs (CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI Clang compiler, not using `uinptr_t` for casts between integers an pointers results in the following `-Werror` build failures: ``` In file included from .../src/truetype/truetype.c:22: .../src/truetype/ttgload.c:1925:22: error: cast from provenance-free integer type to pointer type will give pointer that can not be dereferenced [-Werror,-Wcheri-capability-misuse] node->data = FT_UINT_TO_POINTER( glyph_index ); ^ .../include/freetype/internal/compiler-macros.h:79:34: note: expanded from macro 'FT_UINT_TO_POINTER' ``` * include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER): The ISO C standard compliant fix for this would be to use `uintptr_t` from `stdint.h`, but I am not sure if this is supported by the minimum compiler version. Therefore, use the compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and Clang since about 3.0) before checking for `_WIN64` and falling back to `unsigned long`.
Oleg Oshmyan 5d27b10f 2021-07-13T10:59:32 [base] Fix `FT_Open_Face`'s handling of user-supplied streams. This was already true (though undocumented) most of the time, but not if `FT_NEW` inside `FT_Stream_New` failed or if the `FT_OPEN_XXX` flags were bad. Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the user-supplied stream unchanged, and in case of any subsequent error in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`. Up to now, however, `FT_Stream_New` allocates a new stream even if it is already given one by the user. If this allocation fails, the user-supplied stream is not returned to `FT_Open_Face` and never closed. Moreover, the user cannot detect this situation: all they see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that can also happen after a different allocation fails within the main body of `FT_Open_Face`, when the user's stream has already been closed by `FT_Open_Face`. It is plausible that the user stream's `close` method frees memory allocated for the stream object itself, so the user cannot defensively free it upon `FT_Open_Face` failure lest it ends up doubly freed. All in all, this ends up leaking the memory/resources used by user's stream. Furthermore, `FT_Stream_New` simply returns an error if the `FT_OPEN_XXX` flags are unsupported, which can mean either an invalid combination of flags or a perfectly innocent `FT_OPEN_STREAM` on a FreeType build that lacks stream support. With this patch, the user-supplied stream is closed even in these cases, so the user can be sure that if `FT_Open_Face` failed, the stream is definitely closed. * src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer unnecessarily. Move error-handling code to make the control flow more obvious. Close user-supplied stream if the flags are unsupported. `FT_Stream_Open` always sets `pathname.pointer`, so remove the redundant (re)assignment. None of the `FT_Stream_Open...` functions uses `stream->memory`, so keep just one assignment at the end, shared among all possible control flow paths. ('Unsupported flags' that may need a stream closure can be either an invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean `FT_OPEN_STREAM` flag on a FreeType build that lacks stream support.)
Oleg Oshmyan a4c8f21a 2021-07-13T10:44:38 [base] Reject combinations of incompatible `FT_OPEN_XXX` flags. The three modes are mutually exclusive, and the documentation of the `FT_OPEN_XXX` constants notes this. However, there was no check to validate this in the code, and the documentation on `FT_Open_Args` claimed that the corresponding bits were checked in a well-defined order, implying it was valid (if useless) to specify more than one. Ironically, this documented order did not agree with the actual code, so it could not be relied upon; hopefully, nobody did this and nobody will be hurt by the new validation. Even if multiple mode bits were allowed, they could cause memory leaks: if both `FT_OPEN_STREAM` and `stream` are set along with either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New` allocated a new stream but `FT_Open_Face` marked it as an 'external' stream, so the stream object was never released. * src/base/ftobjs.c (FT_Stream_New): Reject incompatible `FT_OPEN_XXX` flags.
Anuj Verma e592982a 2021-07-13T10:00:22 [sdf] Improve documentation.
Werner Lemberg 205d1ae4 2021-07-12T22:03:25 Small clean-ups for the last few commits. * include/freetype/fttrace.h (afwarp): Removed.
David Turner 2f11522a 2021-06-02T19:05:09 Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably nevery worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purpose.
David Turner 15e88980 2021-06-02T18:54:41 Remove experimental "Latin2" writing system (FT_OPTION_AUTOFIT2) This code has always been experimental and was never compiled anyway (FT_OPTION_AUTOFIT2 does not appear in ftoption.h or even any of our build files).
Dominik Röttsches 286da6c5 2021-06-22T15:01:19 [sfnt] Support PaintScale in 'COLR' v1 parsing. * include/freetype/ftcolor.h (FT_PaintFormat): Renumber values, add `FT_COLR_PAINTFORMAT_SCALE`. (FT_PaintScale): New structure to represent 'PaintScale*' tables. (FT_COLR_Paint): Updated. * src/sfnt/ttcolr.c (FT_PaintFormat_Internal): New enumeration. (read_paint): Parse 'PaintScale' and friends.

Werner Lemberg ff407765 2021-06-25T09:19:51 [base] Add trace level to logging output. Some practical debugging work has shown that displaying level X of an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be very helpful to find out which trace level should be selected. As an example, we now get output like ``` [ttobjs:2] TTF driver [ttobjs:2] SFNT driver [sfobjs:2] not a font using the SFNT container format [t1objs:2] Type 1 driver [stream:7] FT_Stream_EnterFrame: 14 bytes ``` * include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro. (FT_LOG): Use it to add the trace level to the logging tag. * include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH): Adjust. * docs/DEBUG: Updated.

Dominik Röttsches 4cb21b9a 2021-06-22T20:50:48 [sfnt] s/PaintTransformed/PaintTransform/, s/transformed/transform/. * include/freetype/ftcolor.h (FT_PaintTransformed, FT_PaintFormat, FT_COLR_Paint): Do it to make it harmonize with other names such as 'PaintTranslate'. * src/sfnt/ttcolr.c (read_paint, tt_face_get_paint): Ditto.
Dominik Röttsches 284eec1e 2021-06-22T14:21:49 Move 'COLR' API to `ftcolor.h`. * include/freetype/freetype.h: Cut section layer managament containing 'COLR' v0 and v1 API and move it to `ftcolor.h` as requested by Werner on freetype-devel. * include/freetype/ftcolor.h: Paste that section.

Werner Lemberg 36ee7171 2021-06-08T09:00:39 [sdf] Formatting and improved comments.
Anuj Verma 2b1d5562 2021-06-08T08:29:34 [sdf] Use 8 bits for final SDF output instead of 16bits. Since 8-bits is enough to represent SDF data we no longer require 16-bits for this purpose. Also, we now normalize the output data to use the entire 8-bit range efficiently. For example: if we use 3.5 format with a spread of 1 we basically only use the starting 5-bits. By normalizing we can use the entire 8-bit range. * include/freetype/freetype.h (FT_Render_Mode): Updated description for `FT_RENDER_MODE_SDF` regarding this change. * include/freetype/ftimage.h (FT_Pixel_Mode): Removed `FT_PIXEL_MODE_GRAY16` since no longer required. * include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer required. * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit bitmap instead of 16-bit buffer. * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert 16.16 distance value to our desired format. * src/sdf/ftsdf.c (sdf_generate_with_overlaps, sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function and also use 8-bit output buffer. * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead of 16-bit buffer.

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.
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.

(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.
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.

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.

Chris Liddell 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.

Ben Wagner b1286b32 2020-07-09T14:31:00 Document `FT_Face_Rec_::box' with variable fonts (#54969). 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.

David Turner 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'.
David Turner 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'.
David Turner 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.
David Turner 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.
David Turner 0322efb5 2020-07-02T10:31:28 [build] Move mac support code to `mac-support.h'. * 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.
David Turner bd7251ac 2020-07-02T10:24:20 [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.
