encoded in UTF-16BE. Patch from Rajeev Pahuja <rpahuja@esri.com>.
(tt_name_entry_ascii_from_ucs4): Removed.
* include/freetype/ftxf86.h: Fix and extend comment so that it
appears in the documentation.
* include/freetype/ftchapters.h: Add `font_format' section.
* src/tools/docmaker/tohtml.py (HtmlFormatter::index_exit): Add link
to TOC in index page.
Formatting.
src/base/ftlcdfilt.c, src/smooth/ftsmooth.c: API change for
the LCD filter, the FT_LcdFilter value is a enum describing
which filter to apply, new values FT_LCD_FILTER_LIGHT and
FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
algorithm which produces incredible color fringes for everything
except very-well hinted text)
* src/autofit/aflatin.c: various tiny improvements that drastically
improve the handling of serif fonts and of LCD/LCD_V hinting modes.
src/base/ftobjs.c: fixed a bug in the automatic unpatented
hinting support which prevented normal bytecode hinting to
work properly
* src/autofit/aftypes.h: undefining AF_DEBUG to get rid of
traces
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
src/type1/t1gload.c:
this is a major patch used to drastically improve the performance
of loading glyphs. This both speeds up loading the glypn vector
themselves and the auto-fitter.
note that we've started using inline assembler with GCC to
implement FT_MulFix, given that this function is so damn
important for the engine's performance.
the resulting speed-up is about 25%.
src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h,
src/cache/ftcmru.h: copying the cache's internal header files which
were located in 'include/freetype/cache' to the 'src/cache' directory
instead.
Note that these files are not used by FreeType clients, all cache
public APIs have been already moved to include/freetype/ftcache.h,
and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it.
the move is to allow us to modify the internals without intereference
from rogue clients. Note that there are no known client that accesses
the cache internals at the moment.
Re-enable glyph metrics grid-fitting. It is now done in the base
layer.
(FT_Set_Char_Size, FT_Set_Pixel_Sizes): Make sure the width and height
are not too small or too large, just like we were doing in 2.1.10.
* src/autofit/afloader.c (af_loader_load_g): The vertical metrics are
not scaled.
src/base/ftobjs.c, src/base/ftutil.c, src/cff/cffobjs.c,
src/psaux/afmparse.c, src/sfnt/ttbdf.c, src/tools/apinames.c,
src/truetype/ttdriver.c:
solved compiler warnings as well as C++ compilation problems
documentation that negative strength values are possible.
Give an example call.
* include/freetype/freetype.h (FT_GlyphSlotRec): Improve
documentation of `outline' field.
* src/sfnt/sfobjc.s: Inckude FT_INTERNAL_DEBUG_H.
* src/sfnt/sfdriver.c: Include ttmtx.h.
* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
* src/autofit/aflatin.c (af_latin_metrics_init_widths): Use
AF_LatinMetricsRec as the dummy metrics because we cast the metrics to
it later in `af_latin_hints_link_segments'.
to enable autofit CJK script support. (#define'd by default)
* src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro.
* src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure that
`edge_distance_threshold' is always set.
(af_latin_hints_link_segments): Potential divide by 0 bug.
Use latin constant in the scoring formula.
* src/autofit/afcjk.c: Minor updates due to the above three changes.
* docs/TODO, docs/CHANGES: Updated.
patch. You need to #define AF_MOD_CJK in afcjk.c to enable it.
* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,
src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:
Add CJK module based on akito's autohint patch.
* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the
overlap length of the segments. (AF_SEGMENT_LEN, AF_SEGMENT_DIST):
New macros.
* src/autofit/aflatin.h (af_latin_metrics_init_widths),
src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'.
Use the character given by the caller.
(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale
the thresholds.
* src/autofit/afloader.c (af_loader_load_g): Respect
AF_SCALER_FLAG_NO_ADVANCE.
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.
This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.
Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.
* modules.cfg: New file.
* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.
* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables. Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed). We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.
* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files. We no longer use make's `wildcard' function for this.
* Makefile (USE_MODULES): Remove. Update all users.
(OBJ_DIR): Define it here.
* src/*/module.mk: Change
make_module_list: foo
foo: ...
to
FTMODULE_H_COMMANDS += FOO
define FOO
...
endef
in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.
* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.
* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.
* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).
* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.
* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.
* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed. Defined elsewhere.
* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed. Defined elsewhere.
* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.
* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.
* include/freetype/config/ftmodule.h: Add comments -- this file is
no longer used if FreeType is built with GNU make.
* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
Other minor updates.
* modules.txt: Removed. Contents included in `modules.cfg'.
* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.
* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
[FT_STRICT_ALIASING]: Implement.
the warp hinter isn't active (it shouldn't, still experimental)
* Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
and "otvalid" from the list of modules that are linked statically
to a given FreeType library. Functionality has been moved to the
"ftvalid" CVS module.
note also that current Make-based build system still compiles the
modules though...
* include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
which controls the definitions of the memory management functions
to avoid warnings with recent versions of GCC. this macro is
only here to be disabled, in case we detect problems with the
new scheme.
NOTE: disable macro to use the memory debugger. this will be fixed
later !!
