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_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.

* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,
FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros.

* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include
`ttsubpix.c'.

* src/truetype/ttgload.c: Include `ttsubpix.h'.
[All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(tt_get_metrics): Set tweak flags.
(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.
(TT_Process_Simple_Glyph): Compensate emboldening if necessary.

(tt_loader_init): Handle ClearType GETINFO information bits.

* src/truetype/rules.mk (TT_DRC_SRC): Updated.

* src/truetype/ttinterp.c: Include `ttsubpix.h'.
[Where necessary, changes below are guarded by
TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid,
Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45,

pixel.

Oran Agra 2e7a4e9b7f Position Independent Code (PIC) support in truetype driver.
* include/freetype/internal/services/svmm.h add macros to init
instances of FT_Service_MultiMastersRec.
* include/freetype/internal/services/svttglyf.h add macros to init
instances of FT_Service_TTGlyfRec.

* src/truetype/ttdriver.h declare tt_driver_class using macros from
ftdriver.h, when FT_CONFIG_OPTION_PIC is defined create and destroy
functions will be declared.
* src/truetype/ttdriver.c when FT_CONFIG_OPTION_PIC is defined
the following structs:
tt_service_gx_multi_masters, tt_service_truetype_glyf, tt_driver_class
and tt_services array,
will have functions to init or create and destroy them
instead of being allocated in the global scope.
And macros will be used from ttpic.h in order to access them
from the pic_container.
* src/truetype/ttobjs.c change trick_names array to be
PIC-compatible by being a two dimentional array rather than array
of pointers.

New Files:
* src/truetype/ttpic.h declare struct to hold PIC globals for truetype
driver and macros to access them.
* src/truetype/ttpic.c implement functions to allocate, destroy and
initialize PIC globals for truetype driver.

* src/truetype/truetype.c add new file to build: ttpic.c.
* src/truetype/jamfile add new files to FT2_MULTI build: ttpic.c.

David Turner 6aa260ce61 support for "automatic unpatented hinting" added
we still need to determine the list of "trick" CJK fonts
that are going to toggle the bytecode interpreter instead
of the auto-hinter

David Turner 8d3a401fa8 * builds/*/*-def.mk: changed the objects directory from "obj" to "objs"
* include/freetype/config/ftheader.h: removed obsolete macros like
	FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that
	were previously defined in <freetype/ftcache.h>. Added comments to be
	included in a new API Reference section.

	* src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component
	needs to added its own directory to the include path at compile time.
	Modified all "rules.mk" and "descrip.mms" accordingly..
2001-03-20 11:14:24 +00:00
David Turner 170c0d4c0d * include/freetype/config/ft2build.h,
include/freetype/internal/internal.h: fixed header inclusion macros
	to use direct definitions. This is the only way to do these things
	in a portable way :-( The rest of the code should follow shortly
	though everything compiles now..

	* builds/compiler/intelc.mk, builds/compiler/watcom.mk,
	builds/win32/detect.mk: added support for the Intel C/C++ compiler,
	as well as _preliminary_ (read: doesn't work !!) support for Watcom.
	Also added a new setup target. Type "make setup list" for a list
	of supported command-line compilers on Win32..

Werner Lemberg d5c1b27d58 * include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):
Removed.  ANSI C doesn't (explicitly) allow macro expansion in
arguments using `##'.
(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
names directly.  Make them configurable.  Use `##' to strip leading
and trailing spaces from arguments.

* builds/unix/ft2unix.h: Adapted.

* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,
ft_close_stream): Use FT_CALLBACK_DEF.

* builds/unix/ftsystem.c: Use new header scheme.
(FT_Done_Memory): Use free() from FT_Memory structure.

* src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes.

* include/freetype/config/ft2build.h (FT2_CONFIG_ROOT,
FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE,
FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.

David Turner 19ed8afe60 - updated all source files to adhere to the new inclusion scheme
- the CFF loader now loads the encodings and charset tables
  though doesn't use them for now

Werner Lemberg 7fa51b5535 Formatting.
Adding some trivial error checking.

Adding/Fixing tracing levels.
2000-07-08 19:51:42 +00:00
David Turner a90663f591 vast clean-up of the sources in order to allow flat
directory compilation (by defining the FT_FLAT_COMPILE
macro at compile time..)

moved "freetype2/BUILD" to "freetype2/docs/BUILD"
2000-07-08 00:41:13 +00:00
Werner Lemberg 78575dc0d1 A lot of formatting.
Added more tracing levels.

More Makefile fixes.

Minor other changes.
2000-06-12 19:36:41 +00:00
David Turner 8f43c714a5 A major refresh of the TrueType driver :
- some #ifdefs were included in order to _not_
  compile support for the bytecode interpreter
  when FT_CONFIG_OPTION_BYTECODE_INTERPRETER
  is not defined in "ttconfig.h"

- the glyph loader has been seriously re-designed. It is now
  smaller, simpler and should load composites a bit faster

- works with the TrueType debugger
