|
||
|
||
[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).
|
||
|
||
As originally intended, a Type 1 SEAC charstring would be used for
|
||
an accented glyph (like `acaron' or `uumlaut'), where the advance
|
||
width of the SEAC glyph is the same as that of the `base' glyph
|
||
(like `a' or `u'). In this case it is not uncommon for the SEAC
|
||
glyph to not use an (H)SBW opcode of its own but to rely on the
|
||
value from the base glyph.
|
||
|
||
However, out-of-spec fonts also use SEAC glyphs for ligatures (like
|
||
`oe' or `fi'), and in those cases the overall advance width is
|
||
greater than that of the `base' glyph. For this reason we have to
|
||
allow that the SEAC glyph can have an (H)SBW value of its own, and
|
||
if it has, retain this value, rather than the one from the base
|
||
glyph.
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>:
|
||
Implement it.

[smooth] Restore the span buffering for direct mode only.

enough to cover the entire scanline for simple glyphs in most cases:

in-between. This is not new, we used to do it before cb4388783cecc.

[smooth] Simplify cubic Bézier flattening.
|
||
|
||
The previous implementation is correct but it is too complex.
|
||
The revised algorithm is based on the fact that each split moves
|
||
the control points closer to the trisection points on the chord.
|
||
The corresponding distances are good surrogates for the curve
|
||
deviation from the straight line.
|
||
|
||
This cubic flattening algorithm is somewhat similar to the conic
|
||
algorithm based the distance from the control point to the middle of
|
||
the chord. The cubic distances, however, decrease less predictably
|
||
but are easy enough to calculate on each step.
|
||
|
||
The new algorithm produces slightly larger number of splits, which is
|
||
compensated by its simplicity. The overall rendering performance is
|
||
improved by 1-2%. The larger number of splits does not necessarily
|
||
result in higher quality, which stays comparable.

||
|
||
* src/smooth/ftgrays.c (gray_render_cubic): Replace the split
|
||
condition.

[pcf] Fix handling of undefined glyph (#56067).
|
||
|
||
This commit fixes the changes from 2018-07-21, which broke charmap
|
||
iteration. We now add the default character as a new glyph with
|
||
index 0, thus increasing the number of glyphs by one (as before).

|
||
glyph with index 0.
|
||
Limit number of elements to 65534.
|
||
(pcf_get_bitmaps): Ditto.
|
||
Unify two loops into one; this avoids allocation of an intermediate
|
||
array.
|
||
(pcf_get_encodings): Don't flip indices but copy glyph metrics of
|
||
default character to index 0.
|
||
Also handle invalid default character.

[cff] Fix boundary checks.
|
||
|
||
642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically
|
||
allocated memory when parsing CFF files with the "old" engine. Bounds
|
||
checks have never been updated, however, leading to pointless
|
||
comparisons of pointers in some cases. This commit presents a
|
||
solution for bounds checks in the CFF module with an extended logic
|
||
for the "old" engine while staying as concise as possible for the
|
||
"new" one.
|
||
|
||
* src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and

|

* src/psaux/psintrp.c (cf2_interpT2CharString): The call to

`cf2_arrstack_setCount' may fail because the allocator ran out of

memory. When this happens the stack is still written to before the
|
||
error condition is checked. This means that FreeType writes outside

of allocated memory. This commit moves the error check prior to the

stack assignment, hence the function now properly returns with an

All of the Type 1 path building is done with code common to the

invalid outlines were possible.

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 <tony.smith@macro4.com>.

* include/freetype/fttypes.h (FT_BOOL): Add a comparison against

2018-09-21 Ben Wagner <bungeman@google.com>
|
||
|
||
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.

[pcf] Replace charmap implementation.
|

|

PCF comes with charmap lookup table, aka PCF encodings. Using it

* src/truetype/ttgload.c (load_truetype_glyph): Don't use variable

close the frame after loading the header, then use another frame for

[pcf] Massive unsigning (part 1).
|
||
|
||
Unofficial specifications hesitate to use unsigned 32-bit integers.
|
||
Negative values caused a lot of trouble in the past and it is safer
|
||
and easier to treat some properties as unsigned.

* src/pcf/pcf.h (PCF_AccelRec): Use unsigned values for `fontAscent',
|
||
`fontDescent', and `maxOverlap'.

[smooth] Formalize Harmony LCD rendering.
|
||
|
||
This generalizes magic outline shifts that make Harmony LCD
|
||
rendering work in terms of precise two-dimensional RGB subpixel
|
||
positions. These coordinates are now set in time of the `smooth'
|
||
module initialization and later used to shift a glyph outline for
|
||
rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same
|
||
coordinates. The letter, however, rotates them before using.
|
||
The LCD bitmap padding is also calculated using these coordinates.

[base] Fix mono bitmap presetting (#53896).
|
||
|
||
It is rather fundamental to set monochrome bitmap based on rounded
|
||
CBox because the b/w rasterizer turns on pixels when their centers are
|
||
inside the glyph outline. The dropout control is unpredictable and can
|
||
distort narrow glyphs if the bitmap is too wide.

[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.
|
||
|

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)
