766b2c19 | 2021-09-24 22:14:22 | Propagate sign when reading OFF3. Signed 24-bit values are extremely rare. FreeType only reads them in PFR fonts with bitmap strikes conditionally. They have not been seen in the known fonts. That is why this bug could never be discovered. `FT_FRAME_OFF3` propagates sign correctly. * include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE): Propagate sign into 32-bit value. (FT_GET_OFF3, FT_READ_OFF3): Needed fixing but removed as unused. | |

47cf8ebf | 2021-07-28 17:36:57 | [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.

f7c6a06c | 2021-07-12 13:58:10 | 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`. | |

5d27b10f | 2021-07-13 10:59:32 | [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.) | |
|
a4c8f21a | 2021-07-13 10:44:38 | [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. | |

e592982a | 2021-07-13 10:00:22 | [sdf] Improve documentation. | |
|
205d1ae4 | 2021-07-12 22:03:25 | Small clean-ups for the last few commits. * include/freetype/fttrace.h (afwarp): Removed. | |
 |
2f11522a | 2021-06-02 19:05:09 | 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. | |
|
15e88980 | 2021-06-02 18:54:41 | 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). | |
|
286da6c5 | 2021-06-22 15:01:19 | [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. | |

ff407765 | 2021-06-25 09:19:51 | [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. | |

2b1d5562 | 2021-06-08 08:29:34 | [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. | |

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. | |
