|
| +2015-11-15 Werner Lemberg <wl@gnu.org>
|
| +
|
| + * src/autofit/afhints.c (af_get_segment_index): Fix it.
|
| +
|

|
| +
|
| + [autofit] Add functions to get standard widths for writing systems.
|
| +
|
| + We need the computed standard horizontal and vertical widths for the

|
| + all script definitions must implement.
|
| +
|
| + * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New
|
| + function type.
|
| + (AF_WritingSystemClassRec): New member `style_metrics_getstdw'.

|
| +
|
| +2015-11-02 Nikolaus Waxweiler <madigens@gmail.com>
|
| +
|
| + [autofit] Extend `AF_FaceGlobalsRec' to hold emboldening data.
|

| +
|
| +2015-11-02 Bungeman <bungeman@gmail.com>
|
| +
|
| + [ftfuzzer] Add support for multiple files (patch #8779).
|
| +
|
| + Currently, libFuzzer only supports mutation of a single file. We
|
| + circumvent this problem by using an uncompressed tar archive as
|
| + multiple-file input for the fuzzer.
|
| +
|
| + This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing;
|
| + a constructed tarball should contain a font file as the first
|
| + element, and files to be attached as further elements.
|
| +
|
| + * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers.
|
| + (archive_read_entry_data, parse_data): New functions.

| + (LLVMFuzzerTestOneInput): Updated.
|
| +
|
| + * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom
|
| + mutator for libFuzzer that can mutate tarballs in a sensible way.

|
| +

|
| +2015-10-25 Werner Lemberg <wl@gnu.org>
|
| +
|
| + [autofit] Improve tracing.
|

|
| + af_get_edge_index): New functions.
|

|
| + (af_glyph_hints_dump_points): Remove unnecessary `|', `[', and `]'.

|
| + Slightly change printing order of some elements.

|
| + [cff] Avoid overflow/module arithmetic.
|
| +
|
| + This modifies the addition of subroutine number to subroutine bias
|
| + from unsigned to signed, but does not change any results.
|
| +
|
| + * src/cff/cf2ft.c (cf2_initGlobalRegionBuffer,
|

|

|
| +
|
| + [autofit] Redesign code ranges (1/2).
|
| +
|
| + This patch introduces auxiliary code ranges that identify no-base
|
| + characters; they refer to glyphs of a script that should be hinted
|
| + without alignments to blue zones (mostly diacritics).
|
| +
|
| + It also splits off ranges for fallback scripts that handle subscript
|
| + and superscript characters not covered by OpenType features. For
|
| + example, this greatly helps improve the hinting of various phonetic
|
| + alphabets, which contain a large amount characters that look like
|
| + superscript glyphs.
|
| +
|
| + Finally, code ranges are updated to Unicode 8.0, and enclosed
|
| + characters are removed in general since they normally look better if
|
| + they stay unhinted.
|
| +
|
| + * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
|
| + 8.0.
|
| + Split off superscript-like and subscript-like glyphs into...
|
| +
|
| + (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
|
| +
|
| + (af_xxxx_nobase_uniranges): New arrays that hold no-base characters
|
| + of the corresponding character ranges.

|
| +
|
| + [type42] Fix glyph access.
|
| +
|
| + This is a severe bug: We've missed one level of indirection, as
|
| + described in the Type 42 specification. As a result, ftview
|
| + sometimes showed incorrect glyphs for given glyph names, and even
|
| + displayed `error 0x0006' (invalid argument!) in case the number of
|
| + glyph indices differed between the Type 42 font and the embedded
|
| + TTF.
|
| +
|
| + Apparently, noone ever noticed it; this shows how much Type 42 fonts
|
| + are in use...
|
| +
|
| + * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index
|
| + to embedded TTF's glyph index.

|
| +
|
| + * src/type42/t42parse.c (t42_parse_font_matrix): Type 42 FontMatrix
|
| + does not need scaling by 1000. Units_per_EM are taken from the

|
| +
|
| + [truetype] In GX, make private point numbers work correctly.
|
| +
|
| + This is completely missing in Apple's documentation: If a `gvar'
|
| + tuple uses private point numbers (this is, deltas are specified for
|
| + some points only), the uncovered points must be interpolated for
|
| + this tuple similar to the IUP bytecode instruction. Examples that

|
| +
|
| + * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
|
| + tt_handle_deltas): New functions.

|

|
| +
|
| + [truetype] Support selector index 3 of the INSTCTRL instruction.
|
| +
|
| + This flag activates `native ClearType hinting', disabling backwards

|
| + other words, it enables unrestricted functionality of all TrueType
|
| + instructions in ClearType.
|
| +
|
| + * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
|

|
| + `GS.instruct_control' is active.

|

|
| + [truetype] Fix loading of composite glyphs.
|
| +
|
| + * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
|
| + ARGS_ARE_XY_VALUES flag is not set, handle argument values as
|
| + unsigned. I trust `ttx' (which has exactly such code) that it does
|
| + the right thing here...
|
| +
|
| + The reason that noone has ever noticed this bug is probably the fact
|
| + that point-aligned subglyphs are rare, as are subglyphs with a
|
| + number of points in the range [128;255], which is quite large (or
|
| + even in the range [32768;65535], which is extremely unlikely).

|
| +
|
| + [cff] Make the `*curveto' operators more tolerant.
|
| +
|
| + * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
|
| + `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
|
| + pulling values off the stack until the stack is exhausted.
|
| + Implicitly the stack must be a multiple (or for subtly different
|
| + behaviour) a multiple plus a specific number of extra values deep.
|
| + If that's not the case, enforce it (as the old code did).
|
| +
|
| +2015-05-12 Chris Liddell <chris.liddell@artifex.com>
|
| +
|
| + [cff] fix incremental interface with new cff code.
|
| +
|
| + * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
|
| + interface to retrieve glyph data for a SEAC, it be left to the
|
| + incremental interface callback to apply the encoding to raw
|
| + character index (as it was in the previous code).

|
| + Add fallback for glyphs with degenerate bounding boxes.
|
| +
|

|
| +
|
| + No need to create a new glyph loader; we can reuse the one from

|
| +
|
| + [autofit] Remove (unused) support for composite glyphs.
|
| +
|
| + We never have to deal with composite glyphs in the autohinter, as
|
| + those will be loaded into FORMAT_OUTLINE by the recursed
|
| + `FT_Load_Glyph' function.
|
| +
|
| + In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
|
| + FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
|
| + FT_LOAD_NO_HINTING:
|
| +
|
| + /* resolve load flags dependencies */
|
| +
|
| + if ( load_flags & FT_LOAD_NO_RECURSE )
|
| + load_flags |= FT_LOAD_NO_SCALE |
|
| + FT_LOAD_IGNORE_TRANSFORM;
|
| +
|

| + load_flags |= FT_LOAD_NO_HINTING |
|
| + FT_LOAD_NO_BITMAP;
|
| +
|
| + load_flags &= ~FT_LOAD_RENDER;
|
| + }
|
| +
|
| + and as such the auto-hinter is never called. Thus, the recursion in
|
| + `af_loader_load_g' never actually happens. So remove the depth
|
| + counter as well.
|
| +
|
| + * src/autofit/afloader.c (af_loader_load_g): Remove `depth'

| + parameter.

|
| +
|
| + [raster] Fix uninitialized memory access.
|
| +
|
| + Apparently `ras.cProfile' might be uninitialized. This will be the
|
| + case if `ras.top == ras.cProfile->offset', as can be seen in
|
| + `End_Profile'. The overshoot code introduced in a change `Fix B/W
|
| + rasterization of subglyphs with different drop-out modes.' (from
|
| + 2009-06-18) violated this, accessing `ras.cProfile->flags'
|
| + unconditionally just before calling `End_Profile' (which then
|
| + detected that `cProfile' is uninitialized and didn't touch it).
|
| +
|
| + This was harmless, and was not detected by valgrind before because
|
| + the objects were allocated on the `raster_pool', which was always
|
| + initialized. With recent change to allocate raster buffers on the
|
| + stack, valgrind now reported this invalid access.
|
| +
|
| + * src/raster/ftraster.c (Convert_Glyph): Don't access an
|
| + uninitialized `cProfile'.
|
| +
|
| +2015-01-14 Behdad Esfahbod <behdad@behdad.org>
|
| +
|
| + [smooth] Fix uninitialized memory access.
|
| +
|
| + Looks like `ras.span_y' could always be used without initialization.
|
| + This was never detected by valgrind before because the library-wide
|
| + `raster_pool' was used for the worker object and `raster_pool' was
|
| + originally zero'ed. But subsequent reuses of it were using `span_y'
|
| + uninitialized. With the recent change to not use `render_pool' and
|
| + allocate worker and buffer on the stack, valgrind now detects this
|
| + uninitialized access.
|
| +
|
| + * src/smooth/ftgrays.c (gray_raster_render): Initialize

|
| + [raster] Remove 5-level gray AA mode from monochrome rasterizer.
|

|
| + [base] Do not reorder library->renderers upon use.
|
| +
|
| + Instead of keeping `library->renderers' in a MRU order, just leave
|
| + it as-is. The MRU machinery wasn't thread-safe.
|
| +
|
| + With this patch, rasterizing glyphs from different faces from
|
| + different threads doesn't fail choosing rasterizer
|
| + (FT_Err_Cannot_Render_Glyph).
|
| +
|
| + Easiest to see that crash was to add a `printf' (or otherwise let
|
| + thread yield in FT_Throw with debugging enabled).
|
| +
|
| + * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
|
| + (FT_Outline_Render): Don't call `FT_Set_Renderer'.

|
| +
|
| + [raster] Allocate render pool for mono rasterizer on the stack.
|
| +
|
| + Instead of using the `render_pool' member of `FT_Library' that is
|
| + provided down to the rasterizer, completely ignore that and allocate
|
| + needed objects on the stack instead.
|
| +
|
| + With this patch, rasterizing glyphs from different faces from
|
| + different threads doesn't crash in the monochrome rasterizer.
|
| +
|
| + * src/raster/ftraster.c (black_TRaster): Remove `buffer',
|
| + `buffer_size', and `worker' members.
|

|
| +
|
| + [raster] Remove 5-level gray AA mode from monochrome rasterizer.
|
| +
|
| + It was off by default and couldn't be turned on at runtime. And the
|
| + smooth rasterizer superceded it over ten years ago. No point in
|
| + keeping. Comments suggested that it was there for compatibility
|
| + with FreeType 1.

|
| + [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
|
| +
|
| + Previously the code had stipulation for using a per-TT_Size exec
|
| + context if `size->debug' was true. But there was no way that
|
| + `size->debug' could *ever* be true. As such, the code was always
|
| + using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
|
| + This was, clearly, not threadsafe.

| +
|
| + With this patch, loading glyphs from different faces from different
|
| + threads doesn't crash in the bytecode loader code.

| + [autofit] Allocate AF_Loader on the stack instead of AF_Module.
|
| +
|
| + Stop sharing a global `AF_Loader'. Allocate one on the stack during
|
| + glyph load.
|
| +
|
| + Right now this results in about 25% slowdown, to be fixed in a

|
