[truetype] Introduce dynamic limits for some bytecode opcodes.
|
|
|
|
|
|
|
|
|
|
|
|
This speeds up FreeType's handling of malformed fonts.
|
|
|
|
|
|
|
|
|
|
|
|
* src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number
|
|
|
|
|
|
of twilight points, the total number of negative jumps, and the
|
|
|
|
|
|
total number of loops in LOOPCALL opcodes. The values are based on
|
|
|
|
|
|
the number of points and entries in the CVT table.
|
|
|
|
|
|
(Ins_JMPR): Test negative jump counter.
|
|
|
|
|
|
(Ins_LOOPCALL): Test loopcall counter.
|
|
|
|
|
|
|
|

[truetype] Sanitize only last entry of `loca' table.
|
|
|
|
|
|
|
|
|
|
|
|
Without this patch, a loca sequence like `0 100000 0 100000 ...',
|
|
|
|
|
|
where value 100000 is larger than the `glyf' table size, makes
|
|
|
|
|
|
FreeType handle the whole `glyf' table as a single glyph again and
|
|
|
|
|
|
again, which is certainly invalid (and can be very slow, too).
|
|
|
|
|
|
|
|
|
|

* src/truetype/ttpload.c (tt_face_get_location): Implement.
|

[smooth] Reduce divisions in the line renderer.
|
|
|
|
|
|
|
|
|
|
|

We don't need some divisions if a line segments stays within a single
|
|
|

|
|

|
|

[smooth] Fix valgrind warning and reoptimize.
|
|
|
|
|
|
|
|
|
|
|
|
The algorithm calls `gray_set_cell' at the start of each new contour
|
|
|
|
|
|
or when the contours cross the cell boundaries. Double-checking for
|
|
|
|

that is wasteful.

[smooth] Simplify span rendering more.
|
|
|
|
|
|
|
|
|
|
|
|
It turns out that there is significant cost associated with `FT_Span'
|
|
|
|
|
|
creation and calls to `gray_render_span' because it happerns so
|
|
|
|
|
|
frequently. This removes these steps from our internal use but leaves
|
|
|
|
|
|
it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
|
|
|
|
|
|
is about 5%.
|
|
|
|
|
|
|
|
|
|
|
|
* src/smooth/ftgrays.c (gray_render_span): Removed. The code is
|
|
|
|
|
|
migrated to...
|
|
|
|
|
|
(gray_hline): ... here.

[smooth] Streamline pixmap drawing a bit more.
|
|
|
|
|
|
|
|
|

Zero coverage is unlikely (1 out of 256) to warrant checking. This

gives 0.5% speed improvement in rendering simple glyphs.

[smooth] Simplify span rendering.

|
|

|
|
|
|
|
|
This removes unnecessary complexity of span merging and buffering.

[sfnt] Fix `FT_Get_Advance' for bitmap strikes.
|
|
|
|
|
|
|
|
|
|
|
|
`FT_Get_Advance' returns 0 for bitmap fonts. It first gets the
|
|
|
|
|
|
advance value from the font table and then scales it by the
|
|
|
|
|
|
`font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
|
|
|
|
|
|
set that value for bitmap fonts and the advance gets scaled to zero.

[truetype] Add bytecode support for GX variation fonts.
|
|
|
|
|
|
|
|
|
|
|
|
This commit implements undocumented (but confirmed) stuff from
|
|
|
|
|
|
Apple's old bytecode engine.
|
|
|
|
|
|
|
|
|
|
|
|
GETVARIATION[], opcode 0x91
|
|
|
|
|
|
This opcode pushes normalized variation coordinates for all axes
|
|
|
|
|
|
onto the stack (in 2.14 format). Coordinate of first axis gets
|
|
|
|
|
|
pushed first.
|
|
|
|
|
|
|
|
|
|
|
|
GETINFO[], selector bit 3
|
|
|
|
|
|
If GX variation support is enabled, bit 10 of the result is set
|
|
|
|
|
|
to 1.
|
|
|
|
|
|
|
|
|
|
|
|
* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.

is (a) misleading, since the difference to `pos' can be almost

[truetype] Fix gxvar delta interpolation.
|
|
|
|
|
|
|
|
|
|
|
|
The coordinates of the base font should be used for interpolation
|
|
|
|
|
|
purposes, NOT the current points (i.e., the result of accumulation
|
|
|
|
|
|
of previous deltas).
|
|
|
|
|
|
|
|
|
|
|
|
* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
|
|
|
|
|
|
`points_org' before looping over all tuples.
