David Turner 25f845aa64 * src/cache/ftccache.i: fixed a bug that prevented compilation in
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 !
2002-09-09 23:45:29 +00:00
David Turner 00d9f40cf7 * src/smooth/ftsmooth.c, src/base/ftobjs.c,
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)
2002-09-08 21:29:11 +00:00
David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
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_.

            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..

David Turner e459d742e6 * include/freetype/internal/ftmemory.h, and a lot of other files !!:
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..

    I still need to update the documentation in www/freetype2/docs/cache.html
    to reflect the new design though..

2001-10-26 16:58:27 +00:00
Werner Lemberg 80b8d77024 Fixed a bug in `glnames.py' that prevented it from generating
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.
(the_adobe_glyph_list): Renamed to ...
(adobe_glyph_names): This.
(the_adobe_glyphs): Renamed to ...
(adobe_glyph_values): This.
(dump_mac_indices, dump_glyph_list, dump_unicode_values, main):
Updated.
* 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.
(gray_convert_glyph_inner): New function, using setjmp().
(gray_convert_glyph): Use it.


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.
(ftc_manager_init_size, ftc_manager_flush_size): Use
FT_Activate_Size.
2001-10-10 19:56:42 +00:00
David Turner b3ba40ddfd * include/freetype/ftsizes.h, src/base/ftobjs.c, src/cache/ftcmanag.c:
added a new header, named "ftsizes.h" (FT_SIZES_H) to provide a public
	API to manage multiple size objects for a given FT_Face.
2001-10-07 13:30:26 +00:00
David Turner 5b1e81411d * src/cache/ftlru.c (FT_Lru_Lookup_Node): fixed a bug that prevented

2001-03-24 17:10:09 +00:00
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

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.
2000-12-13 23:44:37 +00:00
David Turner 170c0d4c0d * include/freetype/config/ft2build.h,

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.

"FTC_Glyph_Cache" and "FTC_Chunk_Cache", respectively..

note: this is not the end of changes to the cache sub-system
2000-11-06 19:29:06 +00:00

Werner Lemberg ab8552321c Fixing include header for a `make multi' build.
Finishing formatting of cache stuff.

Fixed getDriverClass stuff -- added it to winfnt.c also.  Note that this
still has to be documented.
2000-10-31 22:13:54 +00:00
Werner Lemberg e4b32a5dc5 Removing trailing whitespace. 2000-10-31 20:42:18 +00:00
Werner Lemberg 3dc4374f43 Formatting.
Removed double src/cache/ftcimage.h.

Replaced FTC_Image_Type with #defines since this contains bit flags and not
enumerated values.
2000-10-31 17:49:07 +00:00
David Turner 2909475716 at last, the infamous cache bug is fixed !! 2000-10-31 10:58:23 +00:00
Tom Kacvinsky 6043b2404e In function FTC_ChunkSet_Destroy, changed `manaher' to `manager'. Just
a fix for a silly typo.
2000-10-29 01:47:51 +00:00
David Turner ece6379859 completed the sbit cache, though it's still buggy :-(
major reformatting of the cache subsystem (again)
added substantial documentation too in header files
2000-10-28 23:34:45 +00:00
David Turner 4e4a43631c - completed the abstract chunk cache class
- started implementin a "small-bitmaps" cache derived from it
- (soon a "metrics" cache will be written too)
2000-10-28 13:17:11 +00:00
David Turner 9b8f5c4ce1 small updates:
- 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..
2000-10-28 07:26:59 +00:00
Werner Lemberg ddbb8e7b6a Some formatting.
Fixed some data types/added header files to remove compiler warnings.

David Turner 35db73220c - fixed an horrible FT_LOAD_RENDER bug that returned empty
bitmaps !!

- tested and fixed the image cache object. I'm performing a
  few more checks though, and we'll call the cache sub-system
  completed !!
2000-08-24 12:39:40 +00:00
David Turner 98d2701c58 changed the FTC_Manager_New function to accept "max_faces" and
"max_sizes" parameters
