Werner Lemberg df41fe5791 Whitespace. 2013-08-05 16:34:32 +02:00
Werner Lemberg cc25e3ae12 [autofit] Improve handling of `near' points. 
Points which are very near to each other are now marked as such.
The `weak' flag is then computed by using the `in' vector of the
first and the `out' vector of the last point of a group of near
points.

For example, this fixes the rendering of glyph `Oslash' in
`Roboto-Thin.ttf'.

* src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'.

* src/autofit/afhints.c (af_glyph_hints_reload): Introduce
the heuristic value `near_limit' to decide whether the current point
is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
Store good `in' vector (of last non-near point) in
`last_good_in_{x,y}' and use it as an argument to
`ft_corner_is_flat' if necessary.

Werner Lemberg e3c9301581 */*: Use FT_Err_Ok only. 
This is a purely mechanical conversion.
 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.

 2006-05-17 22:55:04 +00:00
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%.
 2006-05-17 13:34:21 +00:00
Werner Lemberg 1be9ebf5f9 * src/autofit/rules.mk (AUTOF_DRV_SRC): Add afwarp.c.

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
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.
