David Turner c2278680e7 * src/cff/cffload.c (cff_charser_load): modified charset loader to
accept pre-defined charsets, even when the font contains fewer glyphs
2002-11-23 15:53:57 +00:00
Antoine Leca 4b9a7f6bff Updated according to the recent OpenType from Microsoft 2002-11-15 20:05:58 +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 e57ca7dec6 * src/otlayout/otlayout.h, src/otlyaout/otlconf.h,
src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otlparse.c,
        src/otlayout/otlparse.h, src/otlayout/otlutils.h:

          updating the OpenType Layout code, adding support fot the first
          GSUB lookups. Nothing that really compiles for now though

        * src/autohint/ahhint.c: disabled serif stem width quantization. It
        produces slightly better shapes though this is not distinguishable
        with many fonts.

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.

        * src/psaux/psobjs.c (ps_table_add): modified increment loop in

        * src/pcf/pcfdriver.c: adding automatic support for gzip-compressed
        PCF files

        src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h:

        added PFR-specific public API. Fixed the kerning retrievel routine
        (it returned invalid values when the outline and metrics resolution
        differ)

        * src/base/ftsynth.c: fixed the synthetic emboldener. at last.

        * src/base/ftobjs.c: small internal fix to better support
        bitmap-based font formats

src/pfr/pfrgload.c, src/pfr/pfrobjs.c, src/pfr/pfrtypes.h,
        Jamfile, src/base/ftobjs.c: adding support for embedded bitmaps to
        the PFR driver, and rewriting its kerning loader / handler to use all
        kerning pairs in a physical font (and not just the first item).

        * src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
        src/tools/docmaker/tohtml.py: fixing a few nasty bugs

        * src/sfnt/ttcmap0.c: the validator for format 4 sub-tables is
        now capable of dealing with invalid "length" fields at the start
        of the sub-table. This allows fonts like "mg______.ttf" (i.e.
        Marriage) to return accurate charmaps.

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 !!

        and updated constants documentation comments

        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

David Turner d53bfeb810 * src/pshinter/pshalgo.c: slight modification to the Postscript hinter
to slightly increase the contrast of smooth hinting. This is very similar
    to what the auto-hinter does when it comes to stem width computations.
    However, it produces better results with well-hinted fonts..
2002-08-29 22:50:17 +00:00
David Turner d1245c0dd2 updating sources to support the new FT_LOAD_TARGET_ constants
to support target-specific hinting
2002-08-27 22:34:20 +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 9eefed125a Simplified the incremental loading system for CFF fonts and fixed
a problem with the handling of the deprecated version of the Type 2
endchar command, that emulates Type 1 'seac'.

currently under development.
