[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.

[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
|
||
zlib-1.2.8\zlib.h(86): error C2061:
|
||
syntax error: identifier 'z_const'
|
||
zlib-1.2.8\zlib.h(94): error C2054:
|
||
expected '(' to follow 'z_const'
|
||
zlib-1.2.8\zlib.h(94): error C2085:
|
||
'msg': not in formal parameter list
|
||
...
|
||
zlib-1.2.8\zlib.h(877): fatal error C1003:
|
||
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'.
|
||
|
||
* src/gzip/zconf.h: Rename to...
|
||
* src/gzip/ftzconf.h: ... this.
|

* src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

[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.
|
||
|
||
* src/sfnt/pngshim.c (Load_SBit_Png): Add argument to control the
|
||
allocation of the glyph slot.
|
||
* src/sfnt/pngshim.h: Updated.

This also fixes a bug introduced in 2016-10-01 which prevents

display of embedded bitmap fonts that use the `sbix' format.
|
||
|
||
* src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and
|
||
offset also in `ebdt_size' and `ebdt_start', respectively. This
|
||
makes the test for an embedded bitmap data table succeed for this
|
||
format.
|
||
|
||
(tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use
|

`ebdt_size' and `ebdt_start'

Werner Lemberg <wl@gnu.org>
|
||
|
||
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.
|
||
|
||
* include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
|
||
macro.
|
||
|
||
* src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
|

FT_LOAD_BITMAP_METRICS_ONLY is used.
|
||
|
||
* src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap,

[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.
|
||
|
||
https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
|
||
|
||
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'.
|
||
|
||
* src/pcf/pcfread.c (pcf_load_font): Implement it.
|
||
|
||
* docs/CHANGES: Document it.

[ftfuzzer] Speed up.
|
||
|

check for embedded bitmaps if we have a non-default instance.
|

2016-09-29 Werner Lemberg <wl@gnu.org>
|

[truetype] Disallow bitmap strokes for non-default instances.
|

Also speed up access of default instances if GX variations are

active.
|
||
|
||
* include/freetype/internal/tttypes.h (TT_FaceRec): Add
|

`is_default_instance' member.

[truetype] Clean up `TT_Face' structure.

Update documentation.

2016-09-27 Werner Lemberg <wl@gnu.org>
|

|
||
[truetype] Speed up `TT_Load_Glyph'.
|
||
|
||
This avoids additional calls to `tt_face_lookup_table' for the
|
||
`glyf' table, which can be expensive.
|
||
|
||
* include/freetype/internal/tttypes.h (TT_LoaderRec): Move
|
||
`glyf_offset' field to ...

(TT_FaceRec): ... this structure.

[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.
|
||
|

* src/truetype/ttinterp.h (TT_ExecContext): Updated.
|
||
|
||
* docs/CHANGES: Updated.
|
||
|
||
2016-09-25 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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.
|
||
Improve tracing messages.
|
||
|
||
2016-09-25 Werner Lemberg <wl@gnu.org>

||
functions only if we actually do tracing.
|
||
|
||
2016-09-22 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[smooth] Reduce divisions in the line renderer.
|
||
|
||
We don't need some divisions if a line segments stays within a single
|
||
row or a single column of pixels.
|
||
|
||
* src/smooth/ftgrays.c (gray_render_line) [FT_LONG64]: Make divisions
|
||
conditional.
|
||
|
||
2016-09-15 Alexei Podtelezhnikov <apodtele@gmail.com>

2016-09-11 Alexei Podtelezhnikov <apodtele@gmail.com>

2016-09-11 Alexei Podtelezhnikov <apodtele@gmail.com>
|
||
|
||
[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.

2016-09-09 Werner Lemberg <wl@gnu.org>
|
||
|

[sfnt] Don't provide (completely) broken strike data.

`sbit_strike_map' array pointer.

Add tracing message in case of error.
|
||
|
||
* src/sfnt/sfobjs.c (sfnt_load_face): Populate `sbit_strike_map',
|

only using (more or less) valid strike header data for
|
||
FT_Face's `available_sizes' array.
|
||
(sfnt_done_face): Updated.
|
||
|
||
* src/sfnt/ttsbit.c (tt_face_set_sbit_strike): Use

`sbit_strike_map'.

[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.
|
||
|
||
* src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.

[smooth] Simplify span rendering.
|
||
|
||
This removes unnecessary complexity of span merging and buffering.
|
||
Instead, the spans are rendered as they come, speeding up the
|
||
rendering by about 5% as a result.
|
||
|
||
* 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.

[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.

added to `outline->points'.
