|
||
|
||
[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.

The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be

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
|
||

Optimize Bézier bisections.

This change makes bisections faster by 20-30%. When inlined into

noticeable in the overall rendering performance.

[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.

(pcf_get_bitmaps): Ditto.

||
Unify two loops into one; this avoids allocation of an intermediate
|

|

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

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

|
||
|
||
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

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

[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)
