`switch' statement to make it run faster.
(ah_outline_compute_segments): Reset `segment->score' and
`segment->link'.
(ah_outline_link_segments): Provide alternative code which does
the same but runs much faster.
Handle major direction also.
(ah_outline_compute_edges): Scale `edge_distance_threshold' down
after rounding instead of scaling comparison value in loop.
* src/autohint/ahhint.c (ah_hinter_align_stong_points): Provide
alternative code which runs faster.
Handle `before->scale == 0'.
* src/autohint/ahtypes.h (AH_SegmentRec): Move some fields down.
(AH_EdgeRec): Move some fields in structure.
New field `scale'.
* src/sfnt/ttcmap0.c (tt_cmap4_char_next): Use binary search.
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.
2002-11-05 Juliusz <jch@pps.jussieu.fr>
* src/psaux/psobjs.c (ps_table_add): modified increment loop in
order to implement exponential behaviour
src/pfr/pfrgload.c, src/pfr/pfrobjs.c, src/pfr/pfrtypes.h,
Jamfile, src/base/ftobjs.c: adding support for embedded bitmaps to
the PFR driver, and rewriting its kerning loader / handler to use all
kerning pairs in a physical font (and not just the first item).
* src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
src/tools/docmaker/tohtml.py: fixing a few nasty bugs
* src/sfnt/ttcmap0.c: the validator for format 4 sub-tables is
now capable of dealing with invalid "length" fields at the start
of the sub-table. This allows fonts like "mg______.ttf" (i.e.
Marriage) to return accurate charmaps.
* src/autohint/ahtypes.h: disabling metrics hinting in the auto-hinter.
this produces much better anti-aliased text
2002-09-25 Anthony Fok <anthony@thizlinux.com>
* src/sfnt/ttcmap0.c: added support for opens___.ttf (it contains
a charmap that uses offset=0xFFFFU instead of 0x0000 to indicate a
missing glyph)
want to list them all here. The operations performed were all logical
transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE, with
#define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
include/freetype/ftimage.h: adding support for LCD-optimized rendering
though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
this is still work in progress, don't expect everything to work correctly
though most of the features have been implemented.
* adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering
note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.
src/base/ftobjs.c, src/objs/fttype1.c, src/sfnt/ttcmap0.c,
src/smooth/ftgrays.c: changed uses of "setjmp" and "longjmp"
to "ft_setjmp" and "ft_lonjmp". Removed direct references to
<stdio.h> and <setjmp.h> when appropriate, to eventually replace
them with a FT_CONFIG_STANDARD_LIBRARY_H. Useful for the XFree86
Font Server backend based on FT2.
fixed over-restrictive validation test. the charmap validator
now accepts overlapping ranges in format 4 charmaps.
* src/sfnt/ttcmap0.c (tt_cmap4_char_index):
switched to a binary search algorithm. Certain fonts contain
more than 170 distinct segments !!
src/sfnt/Jamfile, src/sfnt/rules.mk,
src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h:
updated the SFNT charmap support to use FT_CMaps
