Werner Lemberg d8a83232af Minor documentation improvement. 2016-11-06 12:33:18 +01:00
Werner Lemberg 37e193e935 Introduce a way of quickly retrieving (embedded) bitmap metrics.
`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
until the user calls `FT_Render_Glyph'.  However, it always
allocates memory for bitmaps and copies or decodes the contents of a
bitmap glyph, which can be quite slow for PNG data.

* include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
macro.

* src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
FT_LOAD_BITMAP_METRICS_ONLY is used.

tt_sbit_decoder_load_bitmap): Add argument to control allocation of
the glyph slot.

`FT_LOAD_BITMAP_METRICS_ONLY' is set.

Werner Lemberg 24aa9c665e [autofit] Rewrite HarfBuzz interface to support character clusters.
Scripts like Khmer have blue zones that can't be directly
represented by Unicode characters.  Instead, it is necessary to let
HarfBuzz convert character clusters into proper glyph representation
forms, then deriving the blue zone information from the resulting
glyphs.

* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
files, providing a new API to access HarfBuzz.

The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
string with function `af_shaper_get_cluster', and the resulting
glyph data (indices, advance widths, vertical offsets) can be
iteratively accessed with function `af_shaper_get_elem'.

Werner Lemberg 14d6b5d748 [truetype] Introduce named instance access to GX fonts.

Werner Lemberg 8502c98b15 Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include).  After this commit, only `ft2build.h' stays in
the compiler's include path.

No visible changes for the user who follows the standard FreeType
header inclusion rules.

* include/*: Move to ...
* include/freetype2/*: This directory, except `ft2build.h'.

Behdad Esfahbod 5163425344 [base] Don't allocate `library->raster_pool' anymore.
It's unused after the following commits:

  [raster] Allocate render pool for mono rasterizer on the stack.
  [raster] Remove 5-level gray AA mode from monochrome rasterizer.

The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
serve, which is, to adjust the pool size.  But the pool is now
allocated on the stack on demand.

* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
2015-01-14 18:30:59 +01:00
Behdad Esfahbod 8dc8635874 [raster] Remove 5-level gray AA mode from monochrome rasterizer.
It was off by default and couldn't be turned on at runtime.  And the
smooth rasterizer superceded it over ten years ago.  No point in
keeping.  Comments suggested that it was there for compatibility
with FreeType 1.

550 lines down.

* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
RASTER_GRAY_LINES): Remove macros and all associated code.

(black_TWorker): Remove `gray_min_x' and `gray_max_x'.

Werner Lemberg a67c43e1c8 Avoid compiler warnings on x86-64 for `FT_MulFix'.
`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',
but several inline implementations of it in `ftcalc.h' take
`FT_Int32' arguments.  This is causing compiler warnings on x86-64:
If parameters of type `FT_Fixed' (= `FT_Long') are passed to the
inline implementation of this function, integer values are truncated
from 64bit to 32bit.

suzuki toshiya e2d2b1544f [ftrfork] Fix the face order difference between POSIX and Carbon.
The fragmented resources in Suitcase and .dfont should be reordered
when post resource for Type1 is being restored, but reordering of
sfnt resources induces the different face order.  Now the ordering
is restricted to post resource only, to prevent the different order
issue  (e.g. the face index in the fontconfig cache generated with
Carbon framework is incompatible with that by FreeType2 without
Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

Werner Lemberg 1924134710 Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to access
OpenType features for handling glyphs not addressable by the cmap.

Right now, compilation of HarfBuzz is only added to the development
build.  A solution for standard build mode will be delayed until
HarfBuzz gets split into two libraries to avoid mutual dependencies
between FreeType and HarfBuzz.

Note that this is only a first step in handling coverages, basically
providing the framework only.  Code for handling selected OpenType
features (this is, actually using the data in `afcover.h') will
follow.

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

Werner Lemberg fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.

When using `ADD' with an immediate operand, the instruction is

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

  Get_Glyph                  0.463 us/op
  Get_CBox                   0.077 us/op
  Get_Char_Index             0.023 us/op
  Iterate CMap              13.898 us/op
  New_Face                  12.368 us/op

  Get_BBox                   0.302 us/op

After:

  Load                       4.617 us/op
  Load_Advances (Normal)     4.645 us/op
  Load_Advances (Fast)       0.027 us/op
  Render                     2.789 us/op
  Get_Glyph                  0.460 us/op
  Get_CBox                   0.077 us/op
  Get_Char_Index             0.024 us/op
  Iterate CMap              13.403 us/op
  New_Face                  12.278 us/op
  Embolden                   0.028 us/op
  Get_BBox                   0.301 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.

For convenience, (most of) the new files are committed separately.

* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
* include/freetype/ftcffdrv.h: New file to access CFF driver
properties.

engine listens to them).
* src/cff/cffgload.c: Include `cf2ft.h'.
(cff_decoder_prepare): Initialize `current_subfont'.
(cff_build_add_point): Handle Adobe engine which uses 16.16
coordinates.
(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
separately.
Choose rendering engine based on `hinting_engine' property.
* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
engine.
* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.

The idea is to replace code like

  return FT_Err_Foo_Bar;

or

  return CFF_Err_Foo_Bar;

with

  return FT_THROW( Foo_Bar );

The FT_THROW macro has two functions:

  . It hides the module specific prefix.

  . In debug mode, it calls the empty function `FT_Throw' which can
    be thus used to set a breakpoint.
