David Turner b28908860d Optimize FT_MulFix for x86_64 GCC builds.
This patch provides an optimized `FT_MulFix' implementation for
x86_64 machines when FreeType is built with GCC, or compatible
compilers like Clang.

Example:
  bin/ftbench -p -t 5 -s 14 -f 0008 Arial.ttf

Before:

  Load                       4.863 us/op
  Load_Advances (Normal)     4.816 us/op
  Load_Advances (Fast)       0.028 us/op

David Turner a5f33eeb8a Speed up ARMv7 support.
When building for ARMv7 with thumb2 instructions, the optimized
`FT_MulFix_arm' assembly routine was not being used.

The reason for this is in the `ftconfig.h' header, namely:

- The assembly routine uses the `smull' instruction which is not
  available when generating Thumb-1 machine code.  It is available
  in Thumb-2 mode, though.

- The header was written a long time ago before Thumb-2 became
  widely popular (e.g. with Android).  So it simply doesn't use the
  assembly routine if the `__thumb__' built-in macro is defined.

- When compiling in Thumb-2 mode, the compiler will define both
  `__thumb__' and `__thumb2__'.

By checking for `(__thumb2__ || !__thumb__)', we ensure that the
assembly routine is only avoided when generating Thumb-1 code.

Given that this is performance-sensitive function, this improves
`ftbench' as follows on a Galaxy Nexus:

Behdad Esfahbod 760d342d37 Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification

  https://color-emoji.googlecode.com/git/specification/v1.html

which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images.  If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.

Note that color bitmaps are converted to grayscale if client didn't
ask for color.

Werner Lemberg 06474c3e5b [cff] Add a new Type 2 interpreter and hinter.
This work, written by Dave Arnold <darnold@adobe.com> and fully
integrated into FreeType by me, is a donation by Adobe in
collaboration with Google.  It is vastly superior to the old CFF
engine, and it will replace it soon.  Right now, it is still off by
default, and you have to explicitly select it using the new
`hinting-engine' property of the cff driver.

Infinality 79e36baebb [truetype] Support subpixel hinting.
This is the large, famous `Infinality' patch to support ClearType
bytecode which has been available from
http://www.infinality.net/blog/ for some time, and which has been
refined over the last years.  While still experimental, it is now
mature enough to be included directly into FreeType.

Most of the code is based on the ClearType whitepaper written by
Greg Hitchcock

  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

which gives a detailed overview of the necessary changes to the
Microsoft rasterizer so that older fonts are supported.  However, a
lot of details are still missing, and this patches provides a
framework to easily handle rendering issues down to the glyph level
of certain fonts.

Note that ClearType support is not completely implemented!  In
particular, full support for the options `compatible_widths',
`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
instruction) is missing.

* src/truetype/ttsubpix.c: New file, providing code to handle
`tweaks', this is, rules for certain glyphs in certain fonts
(including wildcards) which need a special treatment.

* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

* include/freetype/config/ftoption.h, src/devel/ftoption.h

(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.
(TT_Process_Simple_Glyph): Compensate emboldening if necessary.

suzuki toshiya 714ee56ab1 [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
was a configurable macro to disable Carbon-dependent code.  Because
now configure script sets DARWIN_NO_CARBON by default and disables
Darwin & Carbon-dependent codes, these macros can be unified.
FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
(defined by default) is removed, because DARWIN_NO_CARBON violates
FT_XXX naming convention of public macros, and a macro configured by
default is not portable for the building without configure (e.g.
make devel).

* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
old Mac font support is requested and Carbon is available.

suzuki toshiya 0ae3271814 Restrict the number of the charmaps in a rogue-compatible mode.
Fix for Savannah bug #30059.

* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the
minimum character code passed by a legacy rogue client by...
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
This.  It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
undefined (thus the rogue client compatibility is not required).

when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE.

is found after FT_MAX_CHARMAP_CACHEABLE, ignore it and search
earlier one.

Ralph Giles bc0082d512 Improve the comment describing the FT_CONFIG_OPTION_INCREMENTAL option. 2010-01-05 19:41:22 +01:00
Ralph Giles e383729536 Enable the incremental font interface by default.
Ghostscript requires the incremental font interface for handling
some Postscript documents.  It is moving to using FreeType as its
primary renderer; supporting this in the default build makes it
Ghostscript to be linked against the system FreeType when one is
available.

Werner Lemberg ce33a312da FT_USE_MODULE declares things as:
extern const FT_Module_Class

(or similar for C++).  However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.

To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:

  All declarations that refer to the same object or function shall
  have compatible type; otherwise, the behavior is undefined.

(And they are not compatible types.)

Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does.  (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)

Patch from Savannah bug #25133.

* src/base/ftinit.c (FT_USE_MODULE): Include variable type.

* builds/amiga/include/freetype/config/ftmodule.h,
include/freetype/config/ftmodule.h, */module.mk: Updated to declare
pass correct types to FT_USE_MODULE.
