Ben Wagner b1286b32a9 Document `FT_Face_Rec_::box' with variable fonts (#54969).
As pointed out in the "Note:" in the section of

  https://docs.microsoft.com/en-us/typography/opentype/spec/otvaroverview#variation-data-tables-and-miscellaneous-requirements

  ... the xMin, yMin, xMax, yMax, macStyle and lowestRecPPEM fields in
  the font header ('head') table are not supported by variation data and
  should only be used in relation to the default instance for the font.

Document that `FT_Face_Rec_::box' does not vary with OpenType variable
fonts.

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 cb4a943bc4 [build] Fix multi and C++ builds.
The following builds were failing due to previous changes:

* include/freetype/config/ftconfig.h: Remove `FT_END_HEADER'.

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

* src/cache/ftccache.h, src/cache/ftcmru.h, src/pcf/pcfutil.h,
src/psaux/pserror.h, src/psaux/psft.h, src/psaux/psstack.h,

2020-07-06 11:49:00 +02:00
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.

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.

inclusion of `ft2build.h'.
2020-06-13 21:15:45 +02:00
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.

* src/Jamfile, src/*/Jamfile, Jamrules: Delete.

2020-05-12 00:38:46 -04:00
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.
The `smooth' module now handles LCD modes as well.

* src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class.
ft_smooth_lcdv_renderer_class): Deleted.
(ft_render_smooth): Reworked from `ft_render_smooth_generic'.
* src/smooth/ftsmooth.h: Remove dedicated LCD classes.
* src/smooth/module.mk: Remove dedicated LCD modules.
* include/freetype/config/ftmodule.h: Ditto.
* builds/amiga/include/config/ftmodule.h: Ditto.
* include/freetype/ftmodapi.h: Do not mention LCD modules.

Werner Lemberg 26d0f579c0 * include/freetype/internal/ftmemory.h (FT_OFFSET): New macro.
Use this for `base + offset' pointer calculations where `base' can
be NULL (triggering a sanitizer warning even if the resulting
pointer gets never dereferenced since it is undefined behaviour
in C).

Avi Halachmi (:avih) cc17f852d5 [cmake] Don't fail if brotli is missing (#56894).
The libs which cmake controls are commented out at

  include/freetype/config/ftoption.h

and cmake un-comment each enabled library, but the brotli option was
not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained
defined even if brotli was missing/disabled/etc.

Comment it such that cmake can control it, which means leaving it
undefined if brotli is missing.

* include/freetype/config/ftoption.h: Fix typo.

Nikhil Ramakrishnan 1e02076815 [woff2] Avoid too many calls to `FT_REALLOC'.
We do this by using `totalSfntSize' as an initial reference, and
extending the buffer when required.  This reduces rendering time
considerably.

* include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add
`totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'.

* src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep
track of and update total size of stream.

(WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly.

(pad4, store_loca, reconstruct_glyf, reconstruct_hmtx,
reconstruct_font): Update parameters to accept `sfnt_size'.

(woff2_open_font): Add variable `sfnt_size'.  Use WOFF2 header field
`totalSfntSize' as initial reference (if value makes sense) and
allocate `totalSfntSize' bytes for the sfnt stream.  `write_buf'
handles reallocation if and when required.  Also resize the stream
to `actual_sfnt_size' after reconstruction.
