Werner Lemberg f6a25503c5 * devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.

* src/autofit/module.mk (add_autofit_module), src/bdf/module.mk
(add_bdf_module), src/type42/module.mk (add_type42_driver): Fix
whitespace.

* src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv
renderer classes.

David Turner 7213b4febd * builds/unix/configure.ac: fixed build problem on Cygwin
* builds/unix/install.mk: the installation now avoids installing
    the internal headers, and removes existing ones if finds in the
    target install directory

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!

David Turner ff0e9e6c0d * builds/freetype.mk, Jamfile: define the macro FT2_BUILD_LIBRARY
when compiling the library.

    * include/freetype/config/ftheader.h: remove inclusions of
    internal headers, except if the macro FT2_BUILD_LIBRARY is defined.

Wu, Chia-I (吳佳一) bcc438b15e * include/freetype/freetype.h (FT_Select_Size): Rename the second
argument from `idx' to `strike_index'.
(FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of
this enum.

* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,
FT_REQUEST_HEIGHT): New macros to get the width and height of a
request, in fractional pixels.

* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
FT_Request_Metrics): New base functions to set the font metrics.  They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.

* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL.  That is, drivers
should set the metrics themselves.
(FT_Match_Size): Round before matching.  This was what we did and it
does cause some problems without rounding.

* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
(tt_size_select): Set the font metrics.
s/index/strike_index/.
The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected.  This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.

* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
(tt_size_request): Set the font metrics.
Call cff_size_select/tt_size_select when some strike is matched.

src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c:
Set the font metrics.
s/index/strike_index/.

* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
files were committed.  Just a catch-up.
(PS_Conv_ToFixed): Remove the `goto'.
(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.

* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
advertised metrics in `available_sizes' are different from those
actually used.

Werner Lemberg b36bf52795 * src/autofit/afloader.c (af_loader_load_g): Move AF_USE_WARPER up
to avoid compiler warnings.

shadowing variable declarations.
Fix warning parameters and replace printf with AF_LOG.

src/autofit/aftypes.h, src/autofit/afloader.c, src/autofit/autofit.c:

    adding experimental implementation of "warp hinting" (new hinting
    algorithm for gray-level and LCD rendering). It is disabled by default,
    you need to #define AF_USE_WARPER in aftypes.h to enable it.
2006-01-21 14:31:45 +00:00

the linear advance fields as they are only for the outline glyphs.

* include/freetype/freetype.h: Documentation updates/clarificatoins.
The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real
change need be made to the code.

* src/base/ftobjs.c (FT_Load_Glyph): Resolve flag dependencies and
decide whether to use the auto-hinter according to documentation.
There should to be no real difference.
Some checks (e.g., is text height positve?) after the glyph is loaded.

Be careful that scales won't be negative.

David Turner db0182f056 small update 2005-12-14 21:16:33 +00:00
David Turner 89a2a4b531 * include/freetype/config/ftoption.h,
include/freetype/config/ftstdlib.h,
        include/freetype/internal/tttypes.h,
        src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c,
        src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c:

        Added support for an embedded 'BDF ' table within SFNT-based
        bitmap font files. This is used to store atoms & properties from
        the original BDF fonts that were used to generate the font file.

        the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
        and is used to implement FT_Get_BDF_Property for these font files.

        At the moment, this is still experimental, the BDF table format isn't
        cast into stone yet.

David Turner 8def3c897f * Jamfile: small fix to ensure that ftexport.sym is placed in the
same location than other generated objects (i.e. within the 'objs'
        directory of the current dir)
2005-12-14 16:38:31 +00:00
David Turner 5b5f382b7d * src/autofit/aflatin.c, src/autofit/afhints.c: changed the
implementation of the LIGHT hinting mode to completely disable
        horizontal hinting. This is an experimental effort to integrate
        David Chester's latest patch without fucking the other hinting
        modes as well.

        Note that this doesn't force auto-hinting for all fonts however.
