|

|

ftcolor.h: Redesign API.
|
||
|
||
While going to implement it I noticed that I need access to most of
|

the `CPAL' elements; I thus plan to add a `cpal' field to
|
||
`TT_FaceRec', which makes most of the previously suggested API
|
||
functions obsolete because the fields will be directly accessible.

[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.
|
||
|
||
* devel/ftoption.h, include/freetype/config/ftoption.h
|
||

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)

|
||
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.

* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive

|

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

[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.

[sfnt] Fix charmap type 2 iterator (#52646).
|
||
|
||
The subsetted demo font of the report that exhibits the bug has a
|
||
very unusual type 2 cmap for Unicode(!): It contains only two
|
||
sub-headers, one for one-byte characters (covering the range 0x20 to
|
||
0xFA), and a second one for higher byte 0x01 (just for character
|
||
code U+0131).

sub-header for higher byte 0x01.

|

|
||
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.
|
||
|
||
LIGHT NORMAL

[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251)
|
||
|
||
The interpreter in Type 1 mode rewinds the charstring after collecting
|
||
all hints for building the initial hintmap (commit d52dd7f). However,
|
||
some charstrings use `endchar' in a final subroutine call, rewinding to
|
||
the start of that subroutine, and only a small section of the actual
|
||
glyph is drawn.

[cff, truetype] Adjust behaviour of named instances.
|
||
|
||
This commit completely separates the interaction between named

instances and variation functions. In particular, resetting the

variation returns to the current named instance (if set) and not to
|

the base font.

instance index.

|
||
[psaux] Change subfont synthesis for CID fonts.
|
||
|
||
Change `t1_make_subfont' to take in the Private dict record as an
|
||
argument. This is because Type 1 and CID font records in FreeType
|
||
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.
|
||
Update references.
|
||
|
||
* include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update
|
||
declaration.
|
||
|
||
* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update
|
||
call.

|
||
|
||
[psaux] Extend Adobe interpreter (seac).
|
||
|
||
This concludes the changes needed to add Type 1 support.
|
||
|
||
* src/psaux/psintrp.c: Update includes.
|
||
(cf2_interpT2CharString) <cf2_escSEAC>: Implement this similarly to
|
||
implied seac for CFF.
|
||
|
||
* src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode_ps): New
|
||
function to look up the glyph index.
|
||
|
||
* src/psaux/psft.c (cf2_getT1SeacComponent,
|
||
cf2_freeT1SeacComponent): New functions to get the charstrings for
|
||
seac components.
|
||
|
||
* src/psaux/t1decode.h, src/psaux/psft.h: Update declarations.
|
||
|
||

|
||
[psaux] Extend Adobe interpreter (flex in callothersubr).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString)
|
||
<cf2_escCALLOTHERSUBR>: Fix Flex feature handling (OtherSubrs 0, 1,
|
||
2).
|
||
<cf2_cmdRMOVETO>: Do not actually move the `glyphPath' while doing
|
||
flex. This is to avoid closing the current contour.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[psaux] Extend Adobe interpreter (callothersubr).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString)
|
||
<cf2_escCALLOTHERSUBR>: Copy code from
|
||
`t1_decoder_parse_charstrings' (in `t1decode.c').
|
||
OtherSubr 3 (change hints) should reset the hintmask, so that the

new hints are applied.
|
||
Fix function calls and stack access.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>

||
[psaux] Extend Adobe interpreter (pop).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString): Change how unhandled
|
||
OtherSubr results are stored. Implement the PostScript stack using
|
||
an array.

|
||
|
||
* 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 <ewaldhew@gmail.com>
|
||
|
||

|
||
Allow adding hints mid-charstring.
|
||
<cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands
|
||
for three normal stem hints. This requires some recalculation of
|
||
stem positions.

Correction for left sidebearing.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>

|
||
|
||
* 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'
|
||
must be the first operation in a Type 1 charstring.
|
||
<cf2_cmdHSBW, cf2_escSBW>: Fix data access and add correction for
|
||
left sidebearing.
|
||
|
||

|
||
|
||
* 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 <ewaldhew@gmail.com>
|
||
|
||
[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
|
||
Numbers
|
||
|
||
The subsequent commits will implement these changes and adapt
|
||
accesses of data and objects to the new interpreter.
|
||
|
||
NOTE: Will not compile in the meantime!
|
||
|
||
* src/psaux/psintrp.c: Add opcodes to enum.
|
||
(cf2_interpT2CharString): Copy relevant code over from
|
||
`t1_decoder_parse_charstrings' (in `t1decode.c').
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[type1] Fixes for rendering.
|
||
|
||
The Type 1 advance width calculation passes null for glyph slot,
|
||
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
|

||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[psaux] Add missing objects (2/2).
|
||
|
||
Synthesize a `SubFont' object for Type 1 fonts. This is used in the
|
||
interpreter to access Private dict data, which are stored in
|
||
different places for Type 1 and CFF. This allows the same data to
|
||
be used in either mode.
|
||
|
||
* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy
|
||
required values to a dummy `CFF_SubFont' object. This is similar to
|
||
`cff_make_private_dict'.

* src/psaux/psobjs.h: Add the new declaration.
|
||
|
||
* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto.

|
||
|
||
[psaux] Add missing objects for Type 1 (1/2).
|
||
|
||
Move `CF2_Font' instance to `PS_Decoder'. This is the context for
|
||
the interpreter and since it is currently stored in `CFF_Font', is
|
||
unavailable in Type 1 mode.
|
||
|
||
* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New
|
||
`cf2_instance' field.
|

|
||
to choose which renderer to use.
|

2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[cff] Move and rename `CFF_Driver'.
|
||
|
||
This is so that we can use the same hinting engine parameters for
|
||
Type 1.

||
* include/freetype/internal/cffotypes.h (CFF_Driver): Rename and
|
||
move to...

|
||
|

|
||
`CFF_GlyphSlot', so that we can pretend they are the same in the
|
||
interpreter.
|
||
|
||
* src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point):
|
||
Updated with above changes.
|

||
|
||
Replace the `cf2' file name prefix with `ps' as the Adobe engine
|
||
will be used for both PostScript Types 1 and 2 (CFF) instead of just
|

[psaux, cff] Add new service for inter-module calls.
|
||
|
||
NOTE: Does not compile!
|

`PairSet' table.

[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.

||
optimization for Release configuration throughout the project.
