* include/freetype/internal/ftobjs.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c,
src/pcf/pcfdriver.c, src/pfr/pfrsbit.c, src/sfnt/ttsbit.c,
src/type42/t42objs.c, src/winfonts/winfnt.c: introduced three new functions
to deal with glyph bitmaps within FT_GlyphSlot objects. these are:
ft_glyphslot_free_bitmap
ft_glyphslot_alloc_bitmap
ft_glyphslot_set_bitmap
these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP
flag manually. the font drivers have been modified to use them as well.
* src/cache/ftlru.c: fixed an invalid assertion check
to control memory debugging with FreeType. See the description of
"FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX"
in DEBUG.TXT
* src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c,
ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory
conditions.
* src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a
small memory leak
* src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that
only happened when trying to resize an array would end in an OOM.
* src/smooth/ftgrays.c: removed compiler warnings / volatile bug
* src/truetype/ttobjs.c: removed segmentation fault that happened in
tight memory environments.
when available in Asian fonts
* src/sfnt/ttload.c, src/base/ftobjs.c: changed "asian" to "Asian" in
comments
* src/truetype/ttdriver.c (Set_Char_Sizes): fixed a rounding bug when
computing the scale factors for a given character size in points with
resolution.
the API is likely to change however.
* src/base/fttrigon.c (FT_Angle_Diff): fixing function, it returned
invalid values for large negative angle differences (resulting in
incorrect stroker computations, among other things)
* src/cache/ftccache.c (ftc_node_unlink): removing incorrect
assertion, and changing code to avoid hash table size contraction
* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
adding "ftstroker.obj" to default build, as optional component
* 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
debug mode of template instantiation
* src/cff/cffparse.c: fixed the CFF table loader. It didn't accept
empty arrays, and this prevented the loading of certain fonts.
* src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to
prevent seg fault when hints are provided in an empty glyph !!
* include/freetype/ftimage.h: removed incorrect "zft_" definitions
and updated constants documentation comments
* include/freetype/freetype.h (FT_FaceRec): updating documentation
comment. The "descender" value is always *negative*, not positive !
include/freetype/config/ftmodule.h: updated to correctly support
sub-pixel rendering
* include/freetype/cache/ftcimage.h, include/freetype/cache/ftcsbits.h,
src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
rendering correctly. Definition of FTC_ImageTypeRec that replaces the
obsolete FTC_ImageDesc, and has slightly different fields. The
image type is now determined directly by "load_flags" values.
* src/autohint/ahtypes.h, src/autohint/ahhint.c,
src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
to the automatic and Postscript hinters !! and sub-pixel hinting now
works correctly (see demo programs)
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_.
- fixed the infamous bug that caused the cache to crash with large fonts.
the hash table buckets array wasn't shrinked correctly during cache
flushes..
src/cache/ftccache.i, src/cache/ftcsbits.c: adding various
experimental optimisations to the cache manager
* src/type42/t42parse.c: removing duplicate function
(parse_font_matrix): Remove unnecessary code.
(parse_sfnts): Initialize some variables.
(t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use
ft_module_driver_has_hinter conditionally.
Moved some type 42 specific structure definitions to...
* include/freetype/internal/t42types.h: New file.
* include/freetype/internal/internal.h (FT_INTERNAL_T42_TYPES_H):
New macro.
* include/freetype/cache/ftcsbits.h (FTC_SBit): Added a new field
`num_grays' for specifying the number of used gray levels.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.
Adding a driver for BDF fonts written by Francesco Zappa Nardelli
<Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to
better adapt it to FreeType, removing unneeded stuff. Additionally,
it now supports Mark Leisher's BDF extension for anti-aliased
bitmap glyphs with 2 and 4 bpp.
* src/bdf/*: New driver.
* include/freetype/internal/bdftypes.h: New file.
* include/freetype/internal/fttrace.h: Added BDF driver components.
* include/freetype/fterrdef.h: Added error codes for BDF driver.
* include/freetype/config/ftmodule.h, src/Jamfile: Updated.
* include/freetype/internal/internal.h (FT_INTERNAL_BDF_TYPES_H):
New macro.
* include/freetype/config/ftstdlib.h (ft_sprintf): New alias for
sprintf.

added the new configuration file "ftstdlib.h" used to define
aliases for all ISO C library functions used by the engine
(e.g. strlen, qsort, setjmp, etc...)
this eases the porting of FreeType 2 to exotic environments like
XFree86 modules/extensions..
also removed many #include <string.h>, #include <stdlib.h>, etc...
from the engine's sources where they're not needed..
changed the names of memory macros. Examples:
MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
MEM_Move => FT_MEM_MOVE
ALLOC => FT_ALLOC
FREE => FT_FREE
REALLOC = >FT_REALLOC
FT_NEW was introduced to allocate a new object from a _typed_
pointer..
note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
arguments.
This results in _lots_ of sources being changed, but makes the
code more generic and less error-prone..
* src/pshinter/pshalgo2.c (psh2_hint_table_init),
src/pshinter/pshalgo1.c (psh1_hint_table_init): removed compiler
warnings
* include/freetype/cache/*, src/cache/*: yet another massive rewrite of
the caching sub-system, in order to both increase performance and allow
simpler cache sub-classing. As an example, the code for the image and
sbit caches is now much simpler
I still need to update the documentation in www/freetype2/docs/cache.html
to reflect the new design though..
correct glyph names tables. This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).
* src/tools/glnames.py (mac_standard_names): Fixed.
(t1_standard_strings): Some fixes and renamed to ...
(sid_standard_names): This.
(t1_expert_encoding): Fixed.

* src/psnames/pstables.h: Regenerated.
* src/psnames/psmodule.c (PS_Unicode_Value): Fix offset.
Fix return value.
Use `sid_standard_table' and `ps_names_to_unicode' instead of
`t1_standard_glyphs' and `names_to_unicode'.
(PS_Macintosh_Name): Use `ps_glyph_names' instead of
`standard_glyph_names'.
(PS_Standard_Strings): Use `sid_standard_names' instead of
`t1_standard_glyphs'.
* doc/BUGS, doc/TODO: New documents.
* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.
setjmp() and longjmp() are now used for rollback (i.e. when memory
pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.
* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
too small on 16-bit systems). <limits.h> is included to properly
get the needed data type.
(TCell, TRaster): Use it.
(TRaster): New element `jump_buffer'.
(gray_compute_cbox): Use `RAS_ARG' as the only parameter and get
`outline' from it.
(gray_record_cell): Use longjmp().
(gray_set_cell): Use gray_record_cell() for error handling.
(gray_render_line, gray_render_conic, gray_render_cubic): Simplify.

Provide a public API to manage multiple size objects for a given
FT_Face in the new header file `ftsizes.h'.
* include/freetype/ftsizes.h: New header file,
* include/freetype/internal/ftobjs.h: Use it.
Remove declarations of FT_New_Size and FT_Done_Size (moved to
ftsizes.h).
* include/freetype/config/ftheader.h (FT_SIZES_H): New macro.
* src/base/ftobjs.c (FT_Activate_Size): New function.
* src/cache/ftcmanag.c: Include ftsizes.h.

All internal error codes are now public; unused error codes have
been removed, some are new.
* include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New
macro.
* include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro.

some already existing (internal) error codes local to a module have
been renamed to give them the same name as in the base module.
All make files have been updated to include the local error files.
* src/cid/cidtokens.h: Replaced with...
* src/cid/cidtoken.h: This file for 8+3 consistency.
* src/raster/ftraster.c: Use macros for header file names.
the structure of similar makefiles.
* builds/dos/*.mk: Ditto.
* builds/ansi/*.mk: Ditto.
* builds/win32/win32-def.mk (BUILD): Fix typo.
* builds/compiler/*.mk (CLEAN_LIBRARY): Don't use NO_OUTPUT.
This is already used in the link_*.mk files.
* src/*/Jamfile: Slight changes to make files more cryptic.
* 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..
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: New files.
* 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.
* src/base/ftdebug.c: Added dummy symbol to avoid empty file if
conditionals are off.
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..
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.

(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.
the concrete "FTC_Image_Cache" and "FTC_SBit_Cache" to the abstract
"FTC_Glyph_Cache" and "FTC_Chunk_Cache", respectively..
note: this is not the end of changes to the cache sub-system
- reworked slightly the cache manager to better
differentiate between the abstract class in "ftcglyph.h"
and the FT_Glyph sub-class in "ftcimage.h", and
slightly reduced the size of FTC_GlyphNodeRec, saving
8 bytes on a 32-bit system. Yes, I'm crazy ;-)
- added build files to compile with LCC on Unix too
(compile speeds _are_ insane with it). There is unfortunately
a bug in the version I'm using (LCC 4.1) that prevents it
to compile FT_MulTo64 correctly (in src/base/ftcalc.c)
the generated assembly is incorrect, I don't know what
to do ?? the build files are ok, though..
you should invoke "make setup lcc" to select them..
Fixed some data types/added header files to remove compiler warnings.
Added trivial input data check to FT_Outline_Get_BBox().
Fixed type1z -> type1 file inclusions.
its API to enable many kinds of glyph images..
(note that the "ftview" program has been changed to
use the caching sub-system, "ftmulti" and "ftstring"
should come soon).
