FT_Offset, aka size_t, for the size arguments.
2018-09-25 Werner Lemberg <[email protected]>
Fix handling of `FT_Bool'.
Before this commit we had code like
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like
(unsigned char)( 0x8532 & 0x8000)
which in turn expanded to
(unsigned char)( 0x8000)
and finally yielded 0x00 – i.e., false – not as expected.
Problem reported and analyzed by Tony Smith <[email protected]>.
* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.
*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.
2018-09-23 Alexei Podtelezhnikov <[email protected]>
[bdf] Speed up charmap access.
This makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster.
* src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Help binary search
with continuous prediction.
2018-09-22 Alexei Podtelezhnikov <[email protected]>
* src/base/ftobjs.c (ft_glyphslot_preset_bimap): Another tweak.
This one should be clearer. When the rounded monochrome bbox collapses
we add a pixel that covers most if not all original cbox.
2018-09-21 Alexei Podtelezhnikov <[email protected]>
* src/base/ftobjs.c (ft_glyphslot_preset_bimap): Further tweak.
2018-09-21 Ben Wagner <[email protected]>
Improve auto-hinter handling of bitmap fonts (#54681).
For bitmap fonts, `FT_Load_Glyph' should either return an error or
not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this
case `FT_Load_Glyph' calls into the auto-hinter which calls back
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
(even though it doesn't have any path). It appears that the
auto-hinter should not be called when the face doesn't have
outlines. The current test for using the auto-hinter in
`FT_Load_Glyph' checks whether the driver supports scalable
outlines, but not if the face supports scalable outlines.
* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have
scalable outlines.
2018-09-21 Werner Lemberg <[email protected]>
[raster] Fix disappearing vertical lines (#54589).
* src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case
where both left and right outline exactly pass pixel centers.
2018-09-20 Alexei Podtelezhnikov <[email protected]>
* src/base/ftobjs.c (ft_glyphslot_preset_bimap): Tiny rounding tweak.
This adds pixels in case a contour goes through the center
and they need to be turned on in the b/w rasterizer.
2018-09-20 Alexei Podtelezhnikov <[email protected]>
[pcf] Replace charmap implementation.
PCF comes with charmap lookup table, aka PCF encodings. Using it
directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times
faster than the original BDF-like binary searches.
* src/pcf/pcf.h (PCF_EncodingRec): Removed.
(PCF_FaceRec): Remove `nencodings' and `encodings'.
* src/pcf/pcfdrivr.c (pcf_cmap_char_{index,next}): Replaced.
* src/pcf/pcfread.c (pcf_get_encodings): Store data differently.

font name characters is not according to specification.
(get_win_string): Make trace output work if the high byte if
non-zero.
(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
Win PS name (when there is also an Apple PS name); change this into
a fallback to Apple PS name in case the Win PS name is invalid.

* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Remove tracing.
2018-08-26 Werner Lemberg <[email protected]>
[truetype] Avoid nested frames.
Triggered by
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054
* src/truetype/ttgload.c (load_truetype_glyph): Don't use variable
`opened_frame' to trace whether a frame must be closed at the end of
function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which
gets called for space glyphs) uses a frame by itself. Instead,
close the frame after loading the header, then use another frame for
the remaining part of the glyph later on.
Also avoid calling `tt_get_metrics' twice under some circumstances.
2018-08-26 Werner Lemberg <[email protected]>
Various minor clean-ups.
* src/base/ftapi.c: Remove. Unused.
* src/base/Jamfile (_sources): Updated.
* src/base/ftstream.c (FT_Stream_ReleaseFrame): Remove redundant
code.

[truetype] Increase precision while applying VF deltas.
It turned out that we incorrectly round CVT and glyph point deltas
before accumulation, leading to severe positioning errors if there
are many delta values to sum up.
Problem reported by Akiem Helmling <[email protected]> and analyzed
by Behdad.
* src/truetype/ttgxvar.c (ft_var_readpackeddelta): Return deltas in
16.16 format.
(tt_face_var_cvt): Collect deltas in `cvt_deltas', which is a 16.16
format array, and add the accumulated values to the CVT at the end
of the function.
(TT_Vary_Apply_Glyph_Deltas): Store data in `points_org' and
`points_out' in 16.16 format.
Collect deltas in `point_deltas_x' and `point_deltas_y', which are
16.16 format arrays, and add the accumulated values to the glyph
coordinates at the end of the function.

[sfnt] Preliminary support of coloured layer outlines (#44689).
This commit enables OpenType's COLR/CPAL table handling; a typical
application are color emojis that can be scaled to any size.
If the color palette does not exist or is invalid, the rendering
step rasterizes the outline instead. The current implementation
assumes that the foreground is black.
Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.
There are still some issues with metrics; additionally, an API to
fetch color layers is missing.

2018-05-10 Alan Coopersmith <[email protected]>
Fix DLL compilation on Solaris.
AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The
Solaris Studio 12.1 through 12.5 compilers see the
`-fvisibility=hidden' flag, but ignore it with a warning of:
cc: Warning: Option -fvisibility=hidden passed to ld,
if ld is invoked, ignored otherwise
AC_LINK_IFELSE does the compile and then tries to link the result,
at which point the Solaris linker will issue an error:
ld: fatal: option '-fvisibility=hidden' is incompatible with
building a dynamic executable
If we don't use AC_LINK_IFELSE to catch the error, then configure
will fail further tests which attempt to link, such as those testing
dependencies like `libbz2'.
Also, don't try adding `-fvisibility' if we have already added
`-xldscope', just use one of them, since Sun Studio 12 and earlier
compilers only issue a warning, and don't try passing through to the
linker to generate an error, so AC_LINK_IFELSE doesn't catch them.
Tested on Solaris 11.4 beta with compiler versions:
Sun Studio 8 (Sun C 5.5)
Sun Studio 10 (Sun C 5.7)
Sun Studio 11 (Sun C 5.8)
Sun Studio 12 (Sun C 5.9)
Sun Studio 12.1 (Sun C 5.10)
Oracle Solaris Studio 12.2 (Sun C 5.11)
Oracle Solaris Studio 12.3 (Sun C 5.12)
Oracle Solaris Studio 12.4 (Sun C 5.13)
Oracle Developer Studio 12.5 (Sun C 5.14)
Oracle Developer Studio 12.6 (Sun C 5.15)
gcc 5.5.0
gcc 7.3.0
and verified the libfreetype.so.6 generated by each of those
compilers exported the same set of symbols.
* builds/unix/configure.raw: Implement it.

* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
modernization measures.
This brings up the minimum required CMake version to 2.8.12.
The installation paths follow the GNU defaults now, e.g. installing on a
64 bit host will place binaries into the lib64/ folder on e.g. Fedora.
Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).
CMake will no longer look for a C++ compiler.
Library and .so version now match the Autotools build.
Comments in the build file and informational messages now use platform
agnostic example commands.
ftoption.h and ftconfig.h are written directly without a redundant `-new'
copy.
External dependencies are expressed as option()s and will turn up as such
in cmake-gui.
Internal: Properties such as dependencies and include directories are now
privately set on the freetype library instead of globally.
The CPack definitions have been cleaned up, the `make dist' has been
removed. Source packages generated with CPack don't contain Autotools
files and aren't used by the maintainers anyway.
On Windows, src/base/ftver.rc is compiled to decorate the library with
version and copyright information.
A pkg-config file is now generated and installed.

[psaux] Fix Type 1 glyphs with too many stem hints.
According to the CFF specification, charstrings can have up to 96 stem
hints. Due to hint replacement routines in Type 1 charstrings, some
glyphs are rejected by the Adobe engine, which implements the above
limit. This fix turns off hinting for such glyphs.

Use Adobe hinting engine for `light' hinting of both CFF and Type 1.
Since Ewald Hew factored the Adobe hinting engine out of the CFF
driver code, we can now use it on Type 1 (and CID) font formats, as
both have the same hinting philosophy.
This change activates the Adobe hinter when in LIGHT mode, and
therefore always unless explicitly asking for the auto-hinter. This
makes LIGHT behavior consistent with CFF fonts. As of this commit,
the hinting engine table looks as follows.

2017-09-25 Ewald Hew <[email protected]>
[psaux] Fix Type 1 hinting.
Type 1 hinting breaks sometimes when mid-charstring hints should
have been in the initial hintmap. This fix adds a preprocessing
pass that reads all hints and builds the correct initial hintmap
first, before proceeding to build the glyph outline.
* src/psaux/psintrp.c (cf2_interpT2CharString): New
`initial_map_ready' boolean flag.
Ignore outline commands and hint changes on first pass.

have this in different places.
* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to
`FT_Face' so that CID is also accepted.
Take `PS_Private' as an argument and let caller figure out where the
Private dict actually is.

2017-09-25 Ewald Hew <[email protected]>
[psaux] Extend Adobe interpreter (div, four-byte numbers).
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add
Type 1 mode. Type 1 requires large integers to be followed by
`div'; cf. `Adobe Type 1 Font Format', section 6.2.
<op == 255>: Push Type 1 four-byte numbers as `Int' always. This is
to ensure `div' and `callsubr' get values they can use.
2017-09-25 Ewald Hew <[email protected]>

[psaux] Extend Adobe interpreter (hsbw, sbw).
* src/psaux/psintrp.c (cf2_doStems): `hsbw' or `sbw' must be the
first operation in a Type 1 charstring.
(cf2_interpT2CharString): Remove unused variables.
<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'

[psaux] Extend Adobe interpreter (closepath).
* src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>:
Use the right builder function. We can use the `haveWidth' boolean
already present, instead of implementing `parse_state'.
2017-09-25 Ewald Hew <[email protected]>
[psaux] Add Type 1 operations to Adobe CFF interpreter.
The following Type 1 specific ops have been added (copied from
`t1decode'):
closepath
vstem3
hstem3
seac
sbw
callothersubr
pop
setcurrentpoint
hsbw
The following require a Type 1 mode, because of differences in
specification:
hstem
vstem
vmoveto
callsubr
div
rmoveto
hmoveto

etc, which can cause null pointer access in the new interpreter.
Fall back to the old one for now.
Fix the large glyph retry code and ensure hinting and scaling flags
are set properly.
* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a

[otvalid] Fix handling of ValueRecords.
For GPOS pair positioning format 1 the description of ValueRecords

[cff] Fix family name logic of pure CFF fontdata (#52056).
1. If `FamilyName' is present in the CFF font, use this for
FT_Face's `family_name'.
2. Otherwise, use the face name and chop off any subset prefix.
3. If at this point FT_Face's `family_name' is set, use this
together with the full name to determine the style.
4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
5. If we don't have a valid style, use "Regular".
Previously, FT_Face's `family_name' entry for pure CFF fontdata
nearly always was the fontname itself, instead of the `FamilyName'
entry in the CFF font (assuming there is one).
* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
2017-09-18 Alexei Podtelezhnikov <[email protected]>
