Werner Lemberg 26e2a89598 * meson.build: Fix .pc file generation.
For backwards compatibility we need the libtool version, not the .so
number.

Reported by Nikolaus.

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>.
2020-09-24 09:35:24 +02:00
Werner Lemberg bed960d948 * src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics. 2020-09-24 09:31:56 +02:00
Werner Lemberg 3ce0df52e2 [meson] Move auxiliary scripts to `builds/meson`.
Suggested by Alexei.

* scripts/*.py: Move meson scripts to...
* builds/meson/*.py: ... this new location.

* meson.build: Updated.
2020-09-22 20:05:37 +02:00
David Turner d686f2ff9c Add python script for building tarballs.
* scripts/make_distribution_archives.py: New file.

This standalone Python script should be equivalent to running `make
dist` with the Make-based build system, with the following minor
differences:

- Since `make distclean` doesn't always clean up `objs/` properly,
  `make dist` archives may contain some stale binaries like
  `objs/.libs/libfreetype.so.6` or others.

- `config.guess` and `config.sub` are not updated unless option
  `--gnu-config-dir=DIR` is used to specify the location of these
  files.

- Some bits of the auto-generated reference documentation may
  appear in slightly different order, probably due to issues related
  to mkdocs and docwriter.

As an example, the call

  scripts/make_distribution_archives.py /tmp/freetype2-dist

creates the following files under `/tmp/freetype2-dist`:

  freetype-<version>.tar.gz
  freetype-<version>.tar.xz
  ft<winversion>.zip

Werner Lemberg 46417607e6 * scripts/extract_freetype_version.py: Fix regex typos. 2020-09-21 09:21:46 +02:00
David Turner 66978a5887 Add Meson build project file.
Example usage:

  # Configure Meson build in directory `build-meson` to generate
  # release binaries comparable to to the ones from the
  # autotools/make build system.
  meson setup build-meson \
        --prefix=/usr/local \
        --buildtype=debugoptimized \
        --strip \
        -Db_ndebug=true

  # After configuring the Meson build with the above command,
  # compile and install to `/usr/local/`; this includes a pkg-config
  # file.
  ninja -C build-meson install

  # Alternatively, compile and install to `/tmp/aa/usr/local/...`
  # for packaging.
  DESTDIR=/tmp/aa ninja -C build-meson install

  # Generate documentation under `build-meson/docs`.
  ninja -C build-meson docs

Library size comparison for stripped `libfreetype.so` generated by
all three build systems:

  - Default build (autotools + libtool): 712 KiB
  - CMake build (RelWithDebInfo):        712 KiB
  - Meson build:                         712 KiB

* meson.build: New top-level Meson build file for the library.

* meson_options.txt: New file.  It holds user-selectable options for
the build, which can be printed with `meson configure`, and selected
at `meson setup` or `meson --reconfigure` time with
`-D<option>=<value>`.

* scripts/parse_modules_cfg.py: A script invoked by `meson.build` to
parse `modules.cfg` and extract important information out of it
(i.e., the list of modules).

* scripts/process_ftoption_h.py: New script invoked by `meson.build`
to process the original `ftoption.h` file.  It enables or disables
configuration macro variables based on the available dependencies.
This is similar to what other build systems are using (i.e., Meson's
`configure_file()` command is not used here).

* scripts/extract_freetype_version.py: New script invoked by
`meson.build` to extract the FreeType version number from
`<freetype/freetype.h>`.

* scripts/extract_libtool_version.py: New script invoked by
`meson.build` to extract the libtool `revision_info` data from
`builds/unix/configure.raw`, and to generate the corresponding
shared library suffix.

* scripts/generate_reference_docs.py: New script invoked by
`meson.build` to generate the FreeType 2 reference documentation
(using the `docwriter` and `mkdocs` packages, which must be already
installed).

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.
2020-09-11 23:13:02 -04:00
Alexei Podtelezhnikov cb47331369 [raster] Introduce SMART macro.

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'.

David Turner b0667d2d36 [build] Improve visibility support of library function names.
* include/freetype/config/public-macros.h
(FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as
public (and thus exportable).
(FT_EXPORT): Use it.

* include/freetype/config/compiler-macros.h
(FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as
internal to the library (and thus hidden).  Note that on ELF
systems, all internal functions have hidden visibility, which avoids
the need to enforce this when invoking the compiler (e.g., with an
option like `-fvisibility=hidden').

(FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros
to deal with C and C++ linkage issues at the same time.

(FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF,
FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK,
FT_BASE_CALLBACK_DEF): Redefined using new macros.

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
by the library but not to be exposed to clients to...
* include/freetype/config/compiler-macros.h: ...this new file.

* include/freetype/internal/*.h, src/raster/ftraster.h: Include
`compiler-macros.h' where needed.

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.
2020-07-05 09:52:23 +02:00
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.
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.

* 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.

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.
