Werner Lemberg b8b8de80c6 Fix ChangeLog. 2005-05-23 21:34:17 +00:00
Werner Lemberg 92aa527a1c * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.


Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing.  The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'.  But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error.  The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.

* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
cast on lvalue, use a temporary pointer instead.
Cast temporarily to (void*) to not break strict aliasing.

* include/freetype/internal/ftmemory.h (FT_MEM_ALLOC,
FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),
src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*)
to not break strict aliasing.

* src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.

* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.

* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c --
it is currently loaded from ttsbit.c.

David Turner 68df4f732d * src/bdf/bdflib.c: various improvements to the bdf loader, mainly
used to reduce the amount of heap size required to only test wether

    before any test).

    * src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check

David Turner fa0eb0c95f * src/sfnt/ttkern.c (tt_face_load_kern): fixing a small bug which returned
invalid (random) values for the horizontal kerning
2005-02-27 21:35:50 +00:00
David Turner e5680279b2 * many, many files: several memory optimizations were implemented to
drastically reduce the heap usage of FreeType, especially in the case
  of memory-mapped files. The idea is to avoid loading and decoding tables
  in the heap, and instead access the raw data whenever possible (i.e.
  when it doesn't compromise performance).

  This had several impacts: first, opening vera.ttf uses a ridiculous amount
  of memory (when the FT_Library footprint is accounted for), until you start
  loading glyphs. Even then, you'll save at least 20 Kb compared to the non
  optimized case. performance of various operations, including open/close
  has also been dramatically improved.

  More optimisations to come. The auto-hinter eats memory like crazy? This
  must be stopped...
2005-02-26 00:12:04 +00:00
David Turner e70d553111 * include/freetype/config/ftoption.h, include/freetype/internal/ttypes.h,
src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c:
    added the temporary configuration FT_OPTIMIZE_MEMORY to control various
    optimizations used to reduce the heap footprint of memory-mapped TrueType
    files.

    * src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location,
    tt_face_done_loca): when FT_OPTIMIZE_MEMORY is set, the locations table
    is read directly from memory-mapped streams, instead of being decoded
    into the heap.

    * src/truetype/ttpload.c: only load the CVT and fpgm tables when the
    bytecode interpreter is compiled in.
2005-02-22 16:53:06 +00:00
David Turner 3e26d07e60 * src/base/ftdbgmem.c: adding the ability to list all allocation sites
in the memory debugger. Also a new function FT_DumpMemory() was added.
	It is only available in builds with FT_DEBUG_MEMORY defined, and you
	must declare it in your own code to use it, i.e. with something
	like:

	  extern void FT_DumpMemory( FT_Memory );

	  ...

	  FT_DumpMemory( memory );

	* include/freetype/config/ftoptions.h: disabling TrueType bytecode
	interpreter !

	* include/freetype/internal/ftmemory.h: adding FT_ARRAY_ZERO, as a
	convenience macro.

David Turner ebbb0089af ChangeLog update 2004-07-18 07:16:47 +00:00
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.

        * src/cache/ftcmanag.c: fixed a cache flushing bug
2004-07-18 07:15:18 +00:00

I hereby declare the stroker as OFFICIAL !
2004-07-15 21:13:54 +00:00
David Turner 0634a876d9 * src/base/ftstroke (FT_Stroker_ParseOutline): single points
are not stroked, preventing a bug with pala.ttf and other
        fonts.
2004-07-15 21:08:13 +00:00
Werner Lemberg f68cfd096f * src/base/ftstroke (ft_stroke_border_reverse): Removed. Unused. 2004-07-14 21:30:34 +00:00

David Turner 629d7df911 * src/base/ftstroke.c: fixed a bug that prevented the stroker to
correctly generate stroked paths from closed paths, i.e. nearly
        all glyphs in vectorial fonts :-)

        The code is still _very_ buggy though, treat with special care.
2004-07-11 21:09:06 +00:00
Werner Lemberg 5afaa672f3 * src/truetype/ttgload.c (load_truetype_glyph): Fix typo. 2004-06-28 14:19:15 +00:00

* src/base/ftutil.c (FT_QAlloc): Fix error and debug messages.
(FT_QRealloc): Call FT_QAlloc if original pointer is NULL.
Fix error message.
2004-06-24 06:56:06 +00:00
David Turner 4e56c0d8e3 Simple ChangeLog update:
2004-06-23  David Turner   <david@freetype.org>

        * include/freetype/internal/ftmemory.h, src/base/ftutil.c,
        src/base/ftmemdbg.c: introducing the new FT_QAlloc and FT_QRealloc
        functions that do perform allocation without zero-ing out the
        corresponding blocks. Corresponding macros like FT_QALLOC, FT_QNEW,
        etc.. have been defined too

        * include/freetype/config/ftmodule.h: changed the order of modules
        in order to _dramatically_ improve the performance of face open/close
        operations. For example, putting the TrueType driver first in the
        list results in a 5X speedup when opening Vera.ttf !!

        The problem is really that the PCF and/or BDF drivers are broken
        and do a lot more than necessary simply to detect that they
        cannot handle the font file.

        * src/sfnt/ttload.c: small optimization in the kerning table
        verifier, speeds up TrueType face opening by about 7%.

        Also changed code to use the new FT_QNEW_ARRAY call when
        appropriate to slightly improve performance.
2004-06-23 19:29:58 +00:00
Werner Lemberg 8ef4183690 * src/bdf/bdfdrivr.h (BDF_FaceRec): New element `default_glyph'.
* src/bdf/bdflib.c (_bdf_add_property, _bdf_parse_start),
src/bdf/bdf.h (bdf_font_t): s/default_glyph/default_char/.

* src/bdf/bdfdrivr.c (BDF_Face_Init): Fix number of glyphs.
Set `default_glyph'.
(BDF_Glyph_Load): Use `default_glyph' for undefined glyph.

* docs/CHANGES: Updated.
2004-06-22 12:28:17 +00:00
Werner Lemberg 83efe779e3 * src/pcf/pcfread.c (pcf_read_TOC, pcf_get_properties,

slot->metrics.width and slot->metrics.height when loading a Windows
        FNT glyph. Thanks to Huw Davies
2004-06-09 20:27:39 +00:00
David Turner 8530a22888 * include/freetype/freetype.h (FT_Glyph_Metrics, FT_GlyphSlotRec),
src/autofit/afloader.c, src/autohint/ahhint.c:
	moved the definition of 'lsb_delta' and 'rsb_delta' from FT_GlyphMetrics
	to FT_GlyphSlotRec. The old location did BREAK BINARY COMPATIBILITY
	of the library !!

        * src/sfnt/sfobjs.c: removing compiler warning

`lsb_delta' and `rsb_delta'.

* src/autohint/ahhint.c (ah_hinter_load): Set `lsb_delta' and
`rsb_delta' in slot->metrics.
2004-06-04 22:30:10 +00:00
David Turner e664efaddd * src/autofit/*: important fixes to the auto-fitter. The output
now seems to be 100% equivalent to the auto-hinter, while being
        about 2% faster (which proves that script-specific algorithm
        selection isn't a performance problem).

        to test it, change "autohint" to "autofit" in
        <freetype/config/ftmodule.h> and recompile.

        a few more testing is needed before making this the official
        auto-hinting module
