|
||
[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.
|
||
|
||
* src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell.
|
||
(gray_convert_glyph): Remove initialization introduced by 44b172e88.

FT_Face's `available_sizes' array.

|
||
* src/tools/ftrandom/ftrandom.c (GOOD_FONTS_DIR): Provide better

disable the stroke.

|
||
|
||
[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.
|
||
|
||
2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[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.
|
||
|
||
* src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.
|
||
|
||
2016-08-29 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|

This gives 2% speed improvement in rendering simple glyphs.
|
||
|
||
* src/smooth/ftgrays.c (TPixmap): Reduced pixmap descriptor with a
|
||
pointer to its bottom-left and pitch to be used in...
|
||
(gray_TWorker): ... here.
|
||
(gray_render_span): Move pixmap flow check from here...

[sfnt] Cache offset and size to bitmap data table.
|
||
|
||
This commit avoids `EBDT' and friends being looked up again and

again while loading a single embedded bitmap.
|
||
|
||
* include/freetype/internal/tttypes.h (TT_FaceRec)
|
||
[TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: New fields `ebdt_start' and

`ebdt_size'.

[smooth] Simplify span rendering.
|
||
|
||
This removes unnecessary complexity of span merging and buffering.
|

Instead, the spans are rendered as they come, speeding up the

|
||
|
||
* src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed.
|

[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.

[sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
|
||
|
||
Since 2016-05-16 we detect infinite recursion directly.
|
||
|
||
* src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
|
||
`maxComponentDepth'.
|
||
* src/truetype/ttgload.c (load_truetype_glyph): Don't abort if
|
||
`maxComponentDepth' is not valid. Instead, simply adjust its value
|
||
and emit a tracing message.

[truetype] Record the end of IDEFs.
|
||
|
||
To match the logic in FDEF. The value of the end is only used for
|
||
bound-checking in `Ins_JMPR', so it may not have been obvious that
|
||
it was not recorded. Tested (as part of Font Validator 2.0) all the
|
||
fonts on Fedora and did not see any change.
|
||
|
||
* src/truetype/ttinterp.c (Ins_IDEF): Updated.

[truetype] Make GETDATA work only for GX fonts.

(Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'.

[truetype] Add support for Apple's
|
||
|
||
GETDATA[], opcode 0x92
|
||
|
||
bytecode instruction. It always returns 17, and we have absolutely
|
||
no idea what it is good for...
|
||
|
||
* src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.
|
||
(Ins_GETDATA): New function.
|
||
(TT_RunIns): Add it.

|
||
|
||
[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.
|
||
(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
|
||
(Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
|
||
bit 3, checking support for variation glyph hinting.
|
||
(Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
|
||
to implement opcode 0x91.
|
||
(TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.
|
||
|
||
2016-07-16 Werner Lemberg <wl@gnu.org>
|
||
|
||
[truetype] Fix GETINFO bytecode instruction.
|
||
|
||
* src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for
|
||
stretching information.
|
||
|
||

|
||
|
||
[truetype] Make all glyphs in `Zycon' GX font work.
|
||
|
||
* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary
|
||
tests.
|
||
|
||

|
||
|
||
[truetype] Fix GX delta tracing.
|
||
|
||
* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace
|
||
relative point movements.
|
||
|
||
2016-07-16 Behdad Esfahbod <behdad@behdad.org>
|
||
|
||
[truetype] More fixes for GX.
|
||
|
||
This finally fixes the rendering of the cyclist and the lizard in
|
||
the `Zycon' font.
|
||
|
||
* src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
|
||
index is always cumulative.
|
||
|
||
(tt_handle_deltas): Rename to...
|
||
(tt_interpolate_deltas): ... This.
|
||
Add new parameter for output point array.
|
||
Update caller.
|
||
|
||
(TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
|
||
the intermediate results of `tt_interpolate_deltas' that are to be
|
||
added to `outline->points'.
|
||
|
||
2016-07-15 Werner Lemberg <wl@gnu.org>
|
||
|
||
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.
|
||
|
||
`max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.
|
||
|
||
Reported by Alexei.
|
||
|
||
2016-07-16 Nikolaus Waxweiler <madigens@gmail.com>
|
||
|
||
* src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.
|
||
|
||
Problem reported by Hin-Tak Leung.

|
||
|
||
[autofit] Update and improve segment and edge tracing.
|
||
|
||
* src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
|
||
`delta' also.
|
||
Don't show first point of segment as a replacement for `pos'; this
|
||
is (a) misleading, since the difference to `pos' can be almost
|
||
arbitrarily large in corner cases, and (b) it is better to have all
|
||
segment data in font units instead of a single value given in output
|
||
space coordinates.
|
||
Improve layout.
|
||
(af_glyph_hints_dump_edges): Show px->units and units->px conversion
|
||
values for convenience.
|
||
Improve layout.
|
||
|
||
2016-07-15 Werner Lemberg <wl@gnu.org>
|
||
|
||
[autofit] For edges, reject segments wider than 1px (#41334).
|
||
|
||
* src/autofit/afhints.h (AF_SegmentRec): New member `delta'.
|
||
|
||
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute
|
||
`delta'.
|
||
(af_latin_hints_compute_edges): Reject segments with a delta larger
|
||
than 0.5px.
|
||
|
||
2016-07-14 Werner Lemberg <wl@gnu.org>
|
||
|
||
* include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro.
|
||
|
||
2016-07-14 Werner Lemberg <wl@gnu.org>
|
||
|
||
[sfnt] Fix `face_index' value in `FT_Face' for named instances.
|
||
|
||
* src/sfnt/sfobjc.s (sfnt_init_face): Don't strip off higher 16bits.
|
||
|
||
2016-07-14 Werner Lemberg <wl@gnu.org>
|
||
|
||
* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
|
||
|
||
2016-07-14 Behdad Esfahbod <behdad@behdad.org>
|
||
|
||
[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.
