[ftfuzzer] Restrict number of tested bitmap strikes.
|
|
|
|
|
|
|
|
|
|
|
|
Malformed fonts often have large values for the number of bitmap
|
|
|
|
|
|
strikes, and FreeType doesn't check the validity of all bitmap
|
|
|
|
|
|
strikes in advance.

[truetype] Fix linear metrics of GX variation fonts (#49829).
|
|
|
|
|
|
|
|
|
|
|
|
When asking for an unhinted non-default variations,
|
|
|
|
|
|
`linearVertAdvance' is currently the value from the `hmtx' table
|
|
|
|
|
|
instead of the actual value after applying the variation. `HVAR'
|
|
|
|
|
|
support fixes this, but fonts will exist without that table and will
|
|
|
|
|
|
need sane fallback.

[sfnt] Revert change from 2016-12-08.
|
|
|

the change unnecessary.

[gzip] Improve building with external zlib (#49673).
|
|
|
|
|
|
|
|
|
|
|
|
Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
|
|
|
|
|
|
the following error.
|
|
|
|
|
|
|
|
|
|
|
|
ftgzip.c

|
|
|

|
|
|
|
error count exceeds 100; stopping compilation
|
|
|
|
|
|
|
|
|
|
|
|
The error happens because FreeType keeps an own copy of zlib-1.1.4
|
|
|
|
|
|
under `src/gzip'. When building `src/gzip/ftgzip.c' with
|
|
|
|
|
|
FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
|
|
|
|
|
|
|
|
|
|
|
|
#include <zlib.h>
|
|
|
|
|
|
|
|
|
|
|
|
which correctly finds an external `zlib.h', but `zlib.h' itself has
|
|
|
|
|
|
a line
|
|
|
|
|
|
|
|
|
|
|
|
#include "zconf.h"
|
|
|
|
|
|
|
|
|
|
|
|
which makes Visual Studio 2015 find `src/gzip/zconf.h' while
|
|
|
|
|
|
compiling the files in `src/gzip'.
|
|
|
|

[sfnt] Improve FT_LOAD_BITMAP_METRICS_ONLY for `sbix' format.
|
|
|
|
|
|
|
|
|
|

It's unavoidable to call the PNG engine, but to get the metrics it
|

is sufficient to read the PNG image's header only.

|
|
Introduce a way of quickly retrieving (embedded) bitmap metrics.
|
|
|
|
|
|
|
|
|
|
|
|
`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
|
|
|
|
|
|
until the user calls `FT_Render_Glyph'. However, it always
|
|
|
|
|
|
allocates memory for bitmaps and copies or decodes the contents of a
|
|
|
|
|
|
bitmap glyph, which can be quite slow for PNG data.

[pcf] Enrich family name with foundry name and glyph width info.
|
|
|
|
|
|
|
|
|
|
|
|
This is a very old patch from openSuSE (from 2006, submitted to
|
|

|
|
FreeType in 2011) that I forgot to apply.

|
|

|
|
|
|
|
|
|
Prepend the foundry name plus a space to the family name. There are
|
|
|
|
|
|
many fonts just called `Fixed' which look completely different, and
|
|
|
|
|
|
which have nothing to do with each other. When selecting `Fixed' in
|
|
|
|
|
|
KDE or Gnome one gets results that appear rather random, the style
|
|
|
|
|
|
changes often if one changes the size and one cannot select some
|
|
|
|
|
|
fonts at all.
|
|
|
|
|
|
|
|
|
|
|
|
We also check whether we have `wide' characters; all put together,
|
|
|
|
|
|
we get family names like `Sony Fixed' or `Misc Fixed Wide'.

FT_Face's `available_sizes' array.

[smooth] Simplify span rendering more.

[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.
|
|
|
|
|
|
(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.

[truetype] More fixes for GX.

This finally fixes the rendering of the cyclist and the lizard in

|
|
|
|
|
|
|
|
|
|
|
|
* 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'.

`max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.

[autofit] Update and improve segment and edge tracing.

`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.

[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.
