Werner Lemberg a2da05c2c5 Fix two hinting bugs as reported in
http://lists.nongnu.org/archive/html/freetype-devel/2006-06/msg00057.html.

* include/freetype/internal/tttypes.h (TT_GlyphZoneRec): Add
`first_point' member.

* src/truetype/ttgload.c (tt_prepare_zone): Initialize
`first_point'.
(TT_Process_Composite_Glyph): Always untouch points.

* src/truetype/ttinterp.c (Ins_SHC): Fix computation of
`first_point' and `last_point' in case of composite glyphs.

Werner Lemberg 8e6f8c4d79 Formatting, copyright years, documentation improvements. 2006-02-17 08:07:09 +00:00
Wu, Chia-I (吳佳一) 0d565fdc1d * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove
unused `max_points' and `max_contours'.

* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.

* include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused
`max_components'.

* src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused
`loadSize' and `loadStack'.

* src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),
src/sfnt/ttload.c (tt_face_load_maxp): Update.

* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
defined.

* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)

For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'.  Here, we try to
make this work for _all_ tables.

* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit.  Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.

* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Pretty trace messages.

* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from
`eblc'.

* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
(load_format_20, load_format_25, tt_face_get_ps_name): Use
face->max_profile.numGlyphs, instead of face->root.num_glyphs.

David Turner f7cc181425 * src/base/fttrigon.c (ft_trig_prenorm): fixed a bug that created
invalid computations, resulting in very weird bugs in TrueType
	bytecode hinted fonts

	* src/truetype/ttinterp.c: redefined FT_UNUSED_EXEC to not perform
	a structure copy each time. Wooot. !

Wu, Chia-I (吳佳一) d6d73989b0 * src/truetype/ttinterp.c, src/truetype/ttinterp.h: Update copyright

Wu, Chia-I (吳佳一) 0142e6aff1 * src/truetype/ttinterp.c, src/truetype/ttinterp.h: Remove original
TT_Done_Context and rename TT_Destroy_Context to TT_Done_Context with
slight changes.

* src/truetype/ttobjs.h (tt_slot_init): New function.

* src/truetype/ttobjs.c (tt_driver_init): Initialize execution context
here.
(tt_slot_init): New function to create extra points for the internal
glyph loader. We then use it directly, instead of face's glyph loader,
when loading glyph.

* src/truetype/ttdriver.c: Use tt_slot_init for glyph slot
initialization.
(TT_Load_Glyph): Load flag dependencies are handled here.
Return error if size is NULL.

* src/truetype/ttgload.c: Heavy cleanup and refactor.
(TT_Hint_Glyph): New funcion to hint a zone, prepared by caller.
(TT_Process_Simple_Glyph): Use loader->pp's instead of recalculating.
Use TT_Hint_Glyph.
No need to save/restore loader->stream before/after
TT_Vary_Get_Glyph_Deltas now.
(TT_LOADER_SET_PP): New macro to calculate and set the four phantom points.
(TT_Process_Composite_Component, TT_Process_Composite_Glyph,
load_truetype_glyph): Refactor load_truetype_glyph into these three functions.
Never set exec->glyphSize to 0. (close #13107)
Forget glyph frame before calling TT_Process_Simple_Glyph.
(TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into
these three functions.
Set various fields of `glyph' here, instead of in load_truetype_glyph
and compute_glyph_metrics.
2005-08-16 01:54:59 +00:00
Werner Lemberg 33febc0fb2 * docs/CHANGES: Updated.
Fix handling of NPUSHW if skipped in data stream.

* src/truetype/ttinterp.c (opcode_length): Set value for NPUSHW
to -2.
(SkipCode, TT_RunIns): Use opcode_length value for computation of
bytes to be skipped.

Werner Lemberg dea712b4eb `Activate' gray-scale specifing hinting within the TrueType
bytecode interpreter.  This is an experimental feature which
should probably be made optional.

* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
load_truetype_glyph): Move the code to set the pedantic_hinting flag
to...
(TT_Load_Glyph): Here.
Set `grayscale' flag except for `FT_LOAD_TARGET_MONO'.

* src/truetyep/ttinterp.c (Ins_GETINFO): Return MS rasterizer
version 1.7.
Return rotation and stretching info only if glyph is rotated or
stretched, respectively.
Handle grayscale info.

* src/truetype/ttinterp.h (TT_ExecContextRec): Add `grayscale'
member.

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.

    problem that occured due to the latest auto-hinter changes
2003-02-18 22:25:22 +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_.

Werner Lemberg b1e6e59782 * builds/vms/ftconfig.h: Rename LOCAL_DEF and LOCAL_FUNC to

FT_LOCAL_DEF.

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..
