Ben Wagner 007c109b45 * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak (#59322).
The issue is that `rows` is allocated but will not be freed in the
event that the call to `png_read_image` fails and calls `longjmp`.

Werner Lemberg 40479fad93 [autofit] Synchronize with ttfautohint.
This corresponds to the following commits in the ttfautohint git
repository:

  bb6842bd3bd437b7b4a7921b0376c860f5e73d18  Typo, formatting.
  d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa  Add Medefaidrin script.

* src/autofit/afblue.dat: Add blue zone data for Medefaidrin.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

* src/autofit/afscript.h: Add Medefaidrin standard characters.

* src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin
data.
2020-09-25 17:44:00 +02:00
Werner Lemberg e8ee98e669 Move `scripts/make_distribution_archives.py` to `src/tools`.
* scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR,
_SCRIPT_DIR): Updated to new location.
(main): s/shutils.copyfile/shutils.copy/ to preserve file
permissions.
(main): Prefix source file paths with `git_dir` while copying files
to allow calls of the script from other places than the top-level
directory.
2020-09-25 08:07:43 +02:00
Werner Lemberg 4f13a43ab3 * src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`.
Towards the end of the the function there is a call to
`FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units.
That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY`
is left alone, and is not scaled.

Patch from Eric Muller <emuller@amazon.com>.

Alexei Podtelezhnikov 20186d1be6 [raster] Improve the second pass (#58373).
Besides dropout control the second horizontal sweep is supposed to
clean up straight horizontal edges that are mishandled by the first
vertical sweep when a line passes through pixel centers.  This line
would present as perfectly aligned span edges in the second sweep.

* src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old
implementation with a better one focusing on aligned span edges only.

Alexei Podtelezhnikov c3721642f1 [raster] Tune SMART macro (#58352).
Windows seems to perform smart dropout control at 26.6 precision.
To mimick Windows independent of increased precision, we need to tweak
the macro so that some close calls break down rather than up.

* src/raster/ftraster.c (SMART): Tweak the macro.

Alexei Podtelezhnikov f9f6adb625 [truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND.
For glyphs with OVERLAP_SIMPLE or OVERLAP_COMPOUND, set
FT_OUTLINE_OVERLAP to render them with direct oversampling, which
mitigates artifacts (see 3bb512bc9f).

David Turner 0f35b042e0 [build] Really fix multi and C++ builds.
The following builds were still failing due to previous changes:

  make multi
  make multi CC="c++"
  make CC="c++"

This patch fixes the issues, which were missing includes to get the
right macro definitions in multi-build mode.

Also, `FT_UNUSED' is actually used by third-party code, so move it
back to `public-macros.h' to avoid breaking it.

* include/freetype/config/public-macros.h (FT_EXPORT): Remove
special definition for C++.
(FT_UNUSED): Define here instead of...
* include/freetype/config/compiler-macros.h: ... here.
(FT_FUNCTION_DECLARATION): Remove special definition for C++.
(FT_LOCAL_ARRAY_DEF): Fix definition.

* src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h,
src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.

* include/freetype/config/ftheader.h (FT_BEGIN_HEADER,
FT_END_HEADER): Protect against redefinition.

David Turner bb66c8d8cf [build] Split off more stuff from `ftconfig.h'.
* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off macro definitions
required by the FreeType API headers to...
* include/freetype/config/public-macros.h: ...this new file.

* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h: Split off macro definitions used

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.
2020-07-03 22:29:34 -04:00
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.
2020-07-03 09:02:09 -04:00
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.
2020-06-20 05:31:34 +02:00
Sebastian Rasmussen f594ffdc35 [cff] Fix another two memory leaks (#58629).
* src/cff/cffobjs.c (cff_size_init): If a call to `funcs->create'

sure to free `internal->topfont' and any successfully allocated
subfonts.

Sebastian Rasmussen 2e2f3cb5ba [psaux] Fix memory leak (#58626).

Sebastian Rasmussen 09b98060d3 Fix memory leak (#58624).
* src/base/ftobjs.c (FT_New_Size): Avoid trying to free
  `size->internal`, unless `size' has been allocated. This
  mistake appeared in the fix for 58611.
2020-06-19 18:49:36 +02:00
Alexei Podtelezhnikov 6e722f2eaa [base] Rework d1180b5f95 until further notice.

Sebastian Rasmussen 8ed5a2477e [cff, cid] Fix segfaults in case of error (#58621).
* src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c
(cid_slot_done): If `ft_glyphslot_init' fails to allocate
`internal', then the class' `done_slot' callback (called by
`ft_glyphslot_done') must not dereference the pointer to `internal'.
