David Turner 0322efb5e5 [build] Move mac support code to `mac-support.h'.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off mac-specific stuff
to...
* include/freetype/config/mac-support.h: ...this new file.

* CMakeLists.txt, builds/unix/configure.raw: Remove `/undef ->
#undef' string replacement; the affected code is no longer part of
the `ftconfig.h' template.
2020-07-05 09:59:29 +02:00
David Turner bd7251ac97 [build] Put integer type definitions into `integer-types.h'.
Refactor some of the `ftconfig.h' headers and template to move the
definition of the FreeType integer types (e.g., `FT_Int16') to a
common header file `freetype/config/integer-types.h'.

* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off integer type
definition stuff to...
* include/freetype/config/integer-types.h: ...this new file.

* builds/unix/ftconfig.h.in: Control the definition of
`FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro
`FT_USE_AUTOCONF_SIZEOF_TYPES'.  If these are not defined, auto
detection happens in `integer-types.h' as usual based on `INTXX_MAX'
values.  Otherwise the autoconf-detected values are used.

* builds/unix/configure.raw (CPPFLAGS): Don't include path to
`config' directory.  Instead, ...
(FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.

David Turner a4d9206754 [build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'.
Since we are no longer limited to 8.3 file names, it is simpler to
follow the usual conventions for template files.

* builds/unix/ftconfig.in: Renamed to...
* builds/unix/ftconfig.h.in: ...this.

* CMakeLists.txt, builds/unix/configure.raw: Updated.

Alexei Podtelezhnikov 3bb512bc9f [smooth] Introduce direct oversampling for overlaps.
This implements oversampling to metigate artifacts in pixels partially
covered by overlapping contours.  It turns out that the 4x4
oversampling is sufficient but, at least, quadruples the rendering
time.  The outline has to set FT_OUTLINE_OVERLAP to use this method.

* include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag.
* src/smooth/ftsmooth.c (ft_smooth_render): Check it to...
(ft_smooth_raster_overlap): ... inflate outline and set up direct
rendering for oversampling with...
(ft_smooth_overlap_spans): ... new span function that integrates them.

Alexei Podtelezhnikov 19d39f43d2 [smooth] Use direct rendering mode in Harmony.
Instead of rendering 3 bitmaps side by side and reshuffling, we use
direct rendering to deliver the bitmaps on each third byte.

* src/smooth/ftsmooth.c (ft_smooth_raster_lcd)
[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with...
(ft_smooth_lcd_spans): ... new span function.
2020-07-03 09:17:22 -04:00
Alexei Podtelezhnikov 2d67511a14 [smooth] Separate LCD paths from gray rendering.
This makes `ft_smooth_render' a lot smaller and easier to follow. It
also cleanly separates Harmony and ClearType-style LCD rendering
algorithms. Now I only wish to move LCD filtering and geometry from
FT_Library to FT_Renderer.

* src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here...
(ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here.
[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's.

Sebastian Rasmussen a443474755 [cff] Fix handling of `style_name == NULL' (#58630).
* src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails
by returning NULL in `cff_face_init', `remove_style' is still
called.  This means that the NULL pointer is dereferenced, causing a
crash.

Sebastian Rasmussen f594ffdc35 [cff] Fix another two memory leaks (#58629).

* src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c

`internal', then the class' `done_slot' callback (called by
`ft_glyphslot_done') must not dereference the pointer to `internal'.

David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

David Turner 62fea391fa Remove obsolete HAVE_STDINT_H probing macro.
This macro was updated by the unix configure script and the

Alexei Podtelezhnikov 652f886319 [smooth] Stop using dedicated LCD modules and classes.
The LCD modules were never truly independent. They mostly served as
a way to disable patented LCD rendering, which is no longer necessary.

Moazin Khatti 6a431038c9 [gzip] Support `gzip' encoded header conditionally.
In order to support `gzip' encoded header the call to
`inflateInit2' was modified in commit 6a92b1fadd.
However, this code breaks with the outdated internal version
of zlib.  This is a temporary fix to conditionally support
`gzip' encoded header whenever a system installation of zlib
is being used.

Problem report in

  https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html

* src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to
`inflateInit2' depending on whether the system installation is
being used or the internal copy.

Ben Wagner 11975fe9f6 Fix state of `FT_Face' for buggy `gvar' tables (#57923).
By resetting the blend as implemented with this commit fonts with
invalid `gvar' tables may keep calling into `ft_var_load_gvar' from
`tt_set_mm_blend' and failing, but the font was invalid anyway and
we want to keep seeing the failure in `tt_set_mm_blend'.

* src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of
offset array once.
Allocate arrays after `FT_FRAME_ENTER' (extra check before
allocating and avoid needing to free array later if error entering
frame).
Always call `FT_FRAME_EXIT'.
Consistently set counts immediately after array initialized.
Reset the blend (particularly `blend->glyphoffsets') on failure.
