Werner Lemberg 14d6b5d748 [truetype] Introduce named instance access to GX fonts.
For functions querying a face, bits 16-30 of the face index can hold
the named instance index if we have a GX font.  The indices start
with value 1; value 0 indicates font access without GX variation
data.

Werner Lemberg ffee64afb8 Better tracing of loaded glyphs.
Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").

2013-03-14 11:21:17 +01:00
Werner Lemberg 059bc335ce */*: Use `FT_THROW'.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when

    * 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.

* include/freetype/internal/ftobjs.h (FT_Select_Metrics,

should set the metrics themselves.

does cause some problems without rounding.

(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.

Set the font metrics.

* 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.

(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
advertised metrics in `available_sizes' are different from those
actually used.

Wu, Chia-I (吳佳一) 212aee0d6e * include/freetype/internal/ftobjs.h (ft_fake_vertical_metrics),
src/base/ftobjs.c (ft_fake_vertical_metrics): New function to fake the
vertical metrics.

* src/cff/cffgload.c, src/cid/cidgload.c, src/pcf/pcfdrivr.c,
src/type1/t1gload.c, src/winfonts/winfnt.c: Fake the vertical metrics.
The fake metrics is monotone.

* src/truetype/ttgload.c (compute_glyph_metrics): Some fixes and
formattings in vertical metrics faking.  There are still rooms for
improvements (and so do the CFF module).

(PCF_Glyph_Load), src/winfonts/winfnt.c (FNT_Load_Glyph): Don't set
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.
(FT_Select_Size, FT_Request_Size): Scales are set to wrong values.
Be careful that scales won't be negative.

`pixel_height' is used for nominal height.

* src/base/ftobjs.c (FT_Request_Size): Call `FT_Match_Size' if the
face is bitmap only and driver doesn't provide `request_size'.  This
is added merely for completion as no driver satisfies the conditions.
