David Turner 281679de85 * include/freetype/internal/tttypes.h, src/autofit/afangles.c,
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
        src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
        src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

Wu, Chia-I (吳佳一) 9a2b3b6d55 * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply
return error if table is missing.
Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.

* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
tables.  The last change makes Mac bitmap-only font not load and this
fixes it.

* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error
when FT_CONFIG_OPTION_INCREMENTAL is defined.
2006-02-14 08:37:03 +00:00
Wu, Chia-I (吳佳一) f5aa47beb0 Clean up the SFNT_Interface. Table loading functions are now named
after the tables' tags;  `hdmx' is TrueType-specific and thus the code
is moved to the truetype module; `get_metrics' is moved here from the
truetype module so that the code can be shared with the cff module.

This pass involves no real changes.  That is, the code is moved
verbatim mostly.  The only exception is the return value of
`tt_face_get_metrics'.

* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,

src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.

* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading
and parsing code is moved here.
Move `tt_face_get_metrics' here from the truetype module.  The return
value is changed from `void' to `FT_Error'.

* include/freetype/internal/fttrace.h: New trace: ttmtx.

* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
parsing code is moved here.
New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'.
`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

* src/cff/cffgload.c, src/cff/cffobjs.c: Update.

* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

    units.
  . As we use the glyph's cbox to calculate the top bearing now

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

(FNT_Size_Set_Pixels): To find a strike, first check pixel_height

Synchronize computation of height and width for bitmap strikes.  The

2002-09-05 15:10:54 +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_.

Graham Asher ce12182cfc Modified incremental loading interface to be closer to David Turner's
preferences. The header freetype.h is not now affected, the interface is
specified via an FT_Parameter, the pointer to the interface is hidden in an
internal part of the face record, and all the definitions are in ftincrem.h.

variable.

Graham Asher 13217f2509 Added the incremental loading system for the TrueType driver.
Tested using my own unit test code.

David Turner 318f3befc6 * src/truetype/ttgload.c (TT_Load_Composite_Glyph),
src/base/ftoutln.c (FT_Vector_Transform): fixed Werner's latest
        fix. FT_Vector_Transform wasn't buggy, the TrueType composite loader
        was...
2002-06-26 20:30:37 +00:00
Werner Lemberg 87a2bc7b69 * src/base/ftoutln.c (FT_Vector_Transform): Fix serious typo
(xy <-> yx).
* src/truetype/ttgload.c (load_truetype_glyph): Replace `|' with
`||' to make code easier to read.

David Turner 8cd8907311 * src/truetype/ttgload.c (TT_Load_Glyph): finally fixing the last
bug that prevented FreeType 2.x and FreeType 1.x to produce
          bit-by-bit identical monochrome glyph bitmaps with native TrueType
          hinting. The culprit was a single-bit flag that wasn't set
          correctly by the TrueType glyph loader !!

        * src/otlayout/otlayout.h,
          src/otlayout/otlbase.c,

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..
2002-03-22 13:52:37 +00:00
David Turner a890c29cb0 * include/freetype/internal/ftstream.h,
src/base/ftstream.c, src/cff/cffload.c, src/pcf/pcfread.c,
          src/sfnt/ttcmap.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c,
          src/sfnt/ttpost.c, src/sfnt/ttsbit.c,
          src/truetype/ttgload.c, src/truetype/ttpload.c,
          src/winfonts/winfnt.c:

            changed the definitions of stream macros. Examples:

              NEXT_Byte     => FT_NEXT_BYTE
              NEXT_Short    => FT_NEXT_SHORT
              NEXT_UShortLE => FT_NEXT_USHORT_LE
              READ_Short    => FT_READ_SHORT
              GET_Long      => FT_GET_LONG
              etc..

            also introduced the FT_PEEK_XXXX functions..
2002-03-22 12:55:23 +00:00
David Turner 7d3a26425b * renaming stream macros. Examples:
FILE_Skip    => FT_STREAM_SKIP
           FILE_Read    => FT_STREAM_READ
           ACCESS_Frame => FT_FRAME_ENTER
           FORGET_Frame => FT_FRAME_EXIT
           etc...
