Werner Lemberg eff1ee3bd3 * src/truetype/ttgload.c (load_truetype_glyph): Fix typo. 2005-08-31 20:40:00 +00:00
Werner Lemberg 3bfb1c08c1 * src/truetype/ttgload.c [TT_MAX_COMPOSITE_RECURSE]: Removed.
(load_truetype_glyph): Limit recursion depth by `maxComponentDepth'.
2005-08-29 11:59:18 +00:00
Werner Lemberg 2752bd1a46 * src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline
to (0,0) if bit 1 of the `head' table isn't set.  This improves
rendering of buggy fonts.
2005-08-22 07:11:31 +00:00
Wu, Chia-I (吳佳一) 15c1f5d36f * src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of
ttmetrics here.  TrueType fonts with only sbits always have
ttmetrics.valid set to false.

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.

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.

* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): New functions.
(tt_size_init): Add 4, instead of 2, (phantom) points to twilight zone.
Move code that runs fpgm to tt_size_run_fpgm.
(Reset_Outline_Size): Move code that runs prep to tt_size_run_prep.

David Turner c562162834 * src/sfnt/ftbitmap.c, src/truetype/ttgload.c, src/sfnt/ttcmap.c:
removing compiler warnings (Visual C++ /W4)

        * Jamfile, src/otvalid/{otvcommn.h,otvgdef.c,otvgpos.c,otvgsub.c,
        otvjstf.c}: modified the code to use a different pre-processor trick
        to implement the OTV_NEST1, OTV_NEST2 and OTV_NEST3 macros. The code
        now compiles neatly with Visual C++. The 'otvalid' module has been
        put in the Jamfile build again.
2005-06-30 11:46:46 +00:00

(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Use
ft_glyphslot_grid_fit_metrics.
FT_Outline_Get_CBox is called twice.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more
reasonable values when emboldening outline glyphs.  The theoretic
ones are unrealistic.
2005-06-20 09:04:50 +00:00
Werner Lemberg 49f4d34ed3 * src/base/ftoutln.c (FT_Outline_Embolden): Strength should be
halved.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Change the default
strength.
Don't increase slot->advance.y.



* include/freetype/freetype.h (FREETYPE_MINOR): Set to 2.
(FREETYPE_PATCH): Set to 0.

* builds/unix/configure.ac (version_info): Set to 9:9:3.
Currently, we are still binary compatible.

builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: s/219/2110/, s/2.1.9/2.1.10/.

* builds/freetype.mk (refdoc), README, Jamfile (RefDoc):
s/2.1.9/2.1.10/.

* ChangeLog.20, ChangeLog.21: These new files.



The next release will be 2.2.0, so don't worry about source code
backwards compatibility.

* include/freetype/ftimage.h (FT_Outline_MoveToFunc,
FT_Outline_LineToFunc, FT_Outline_ConicToFunc,
FT_Outline_CubicToFunc, FT_SpanFunc, FT_Raster_RenderFunc),

vertBearingY to make glyphs centered vertically.
Fix some bugs in vertical metrics:

  . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
    units.
  . As we use the glyph's cbox to calculate the top bearing now
    there iss no need to adjust `top'.



* src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
in sync with OTV_OPTIONAL_OFFSET.  Reported by YAMATO Masatake.

  * include/freetype/internal/tttypes.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c,
  src/truetype/ttobjs.c, src/cff/cffobjs.c, src/sfnt/sfobjs.c: implementing new
  heap-optimized embedded bitmap loader. This one also fixes bug #12107

  * src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without
  a 'kern' table.
2005-02-28 22:09:07 +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
Werner Lemberg 85cc0a322e * src/truetype/ttinterp.h: Fix typo. 2004-11-23 22:10:21 +00:00

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'.

2004-07-24 21:57:39 +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

Werner Lemberg ee6e92c28e * src/truetype/ttxgvar.c (ft_var_load_avar): Do free arrays in case
of error -- `avar' is optional so we can't rely on tt_done_blend
being called automatically.
2004-05-11 06:45:27 +00:00
