David Turner 5ab4136317 * include/freetype/cache/ftcglyph.h, src/cache/ftcglyph.c:
fixed a dangling pointer bug that happened in very rare cases:
        i.e. when a new family object was destroyed by an out-of-memory
        condition during a glyph node initialization. The function
        FTC_Cache_Lookup would flush the cache and restart the lookup
        with a bad pointer.

David Turner f546bacdcf * src/sfnt/Jamfile: removing "ttcmap" from the list of sources
* src/cache/*, include/freetype/cache/*: fixing a bug after heavy
        testing. The current sources are now "release candidates" for the
        final version of the cache sub-system

        * Jamfile: updating "refdoc" target, and adding "autohint" to the
        list of modules to build. Both the autohinter and autofitter will be
        built by default. But which one will be used is determined by
        the content of "ftmodule.h"

        * src/autofit/*: much updates, but the code is still buggy as hell.
        Aargh..

        src/cache/ftclru.c (removed):

          *Complete* rewrite of the cache sub-system to "solve" the
          following points:

            - all public APIs have been moved to FT_CACHE_H, everything
              under "include/freetype/cache" is only needed by client
              applications that want to implement their own caches

            - a new function named FTC_Manager_RemoveFaceID to deal
              with the uninstallation of FaceIDs

            - the image and sbit cache are now abstract classes, that
              can be extended much more easily by client applications

            - better performance in certain areas. Further optimizations
              to come shortly anyway...

            - the FTC_CMapCache_Lookup function has changed its signature,
              charmaps can now only be retrieved by index

            - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace
              FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in
              private header for the moment)

Werner Lemberg 4ee9b7bab1 * src/cache/ftcsbits.c (ftc_sbit_node_compare): Only add `size' if
there is no error.  Reported by Knut St. Osmundsen
<bird-freetype@anduin.net>.
2003-07-02 15:03:36 +00:00
Werner Lemberg 779afe4b91 * src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.

* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.


Synchronize computation of height and width for bitmap strikes.  The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes.  The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.

* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.

* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.

* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
argument to function.

* src/psnames/psmodule.c (ps_unicode_value): Handle `.' after
`uniXXXX' and `uXXXX[X[X]]'.

2003-06-12 13:14:15 +00:00
Werner Lemberg 858f310b80 Completely revised FreeType's make management.
. In all makefiles `/' is used as the path separator.  The
  conversion to the real path separators is done as late as
  possible using $(subst ...).

. $(HOSTSEP) no longer exists.  Now, $(SEP) gives the path separator
  for the operating system, and the new $(COMPILER_SEP) the path
  separator for the compiler tools.

. $(BUILD) has been renamed to $(BUILD_DIR).  In general, all
  directory variables end with `_DIR'.  The variants ending in `_'
  (like `BASE_' have been removed).

The following ChangeLog entries only describe changes which are
not related to the redesign.

* builds/beos/beos-def.mk (BUILD_DIR): Fix typo.
* builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid
overlong arguments as suggested by J. Ali Harlow
<ali@avrc.city.ac.uk>.
* builds/dos/dos-wat.mk: New file.
* builds/freetype.mk (FREETYPE_H): Include header files from the
`devel' subdirectory.

* builds/os2/os2-dev.mk, builds/unix/unixddef.mk,
builds/unix/unixddef.mk, builds/win32/w32-bccd.mk,
builds/win32/w32-dev.mk (BUILD_DIR): Fix path.

* builds/unix/configure.ac, builds/unic/configure: Updated.
* builds/unix/unix-def.in (DISTCLEAN): Add `freetype2.pc'.


* devel/ftoption.h: Updated.

David Turner d6ec6eee78 * src/autohint/ahglyph.h, src/autohint/ahglyph.c, src/autohint/ahglobal.c,
src/autohint/ahhint.c: fixed blue-scale problem

    * src/cache/ftccache.c: fixed small bug that could crash the cache
    in rare circumstances (mostly with broken fonts)
2003-03-20 20:58:57 +00:00
David Turner 66cbc20978 * docs/*: serious rewriting of the documentation
* 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
2003-03-20 07:04:40 +00:00
David Turner b280537b6d * src/base/ftdbgmem.c, docs/DEBUG.TXT: added new environment variables
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.
2003-03-13 21:07:51 +00:00
David Turner ae26c684db * src/cache/ftccmap.c: the cmap cache now supports UCS-4 charmaps
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.
2003-02-25 20:37:50 +00:00
David Turner 4bdf4350f2 various improvements for 2.1.4. see ChangeLog, I've got problems with
copy & paste on my desktop !!
2003-01-30 23:24:18 +00:00
David Turner 20e33158da * src/base/ftstroker.c: probably the last bug-fixes to the stroker,
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
2003-01-07 22:54:02 +00:00
David Turner 5237993a92 fixed a small bug in the sbit cache that caused problems with embedded bitmaps 2002-11-07 09:46:43 +00:00
David Turner 60b32e16e7 2002-11-05 David Turner <david@freetype.org>
* 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
2002-11-06 22:32:54 +00:00
Werner Lemberg 98add9e68c Formatting, minor doc fixes. 2002-09-18 11:32:12 +00:00
Werner Lemberg 7a99b507ce * src/type1/t1parse.h (T1_ParserRec): Change type of `base_len'
and `private_len' to FT_Long.

* src/cache/ftcsbits.c (ftc_sbit_node_load): Remove unused label.
* src/pshinter/pshalgo3.c (psh3_hint_align): Remove unused variable.
2002-09-17 07:31:17 +00:00
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_.
2002-08-27 20:20:29 +00:00
Werner Lemberg 3c403e4c17 Some formatting.
* src/cff/cffcmap.c: Remove compiler warnings.

src/cache/ftccache.c: cleaning up the cache sub-system code, linear
    hashing is now the default
2002-07-17 20:56:48 +00:00
David Turner 957fa85682 - removing a typo in ftccache.i that prevented it from compiling correctly
- 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..
2002-06-08 13:48:41 +00:00
Werner Lemberg 995d1165b9 * src/cache/ftccache.i (GEN_CACHE_LOOKUP): Move declaration of
`family' and `hash' up to make it compilable with g++.
2002-06-08 12:50:18 +00:00
Werner Lemberg 8c90c22dbe * src/cache/ftccache.c (ftc_node_hash_unlink, ftc_node_hash_link)

(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.

            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..
2002-04-12 09:31:48 +00:00

2002-03-30 16:41:09 +00:00
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..

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.

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'.

* 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.

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.

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

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.
