David Turner 15e889800a Remove experimental "Latin2" writing system (FT_OPTION_AUTOFIT2)
This code has always been experimental and was never compiled
anyway (FT_OPTION_AUTOFIT2 does not appear in ftoption.h or even
any of our build files).

Tatsuyuki Ishi 0d5f1dd37c [autofit] Fix double division in stem darkening.
The old code used to divide the darkening amount by em_ratio twice,
leading to unnecessarily bold stems on certain fonts with higher
units per em (e.g. Inter). This patch fixes it.

The return value of af_loader_compute_darkening was also changed to
use 16.16 fixed point to get rid of a redundant truncation operation.
This should slightly improve the precision, although it's still
bottlenecked by the emboldening function, which uses 26.6 fixed point.

* src/autofit/afloader.[ch]
(af_loader_compute_darkening): Return FT_Fixed.
(af_loader_embolden_glyph_in_slot): Revise calculations.

David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

Armin Hasitzka a3cfed5e87 Fix pointer underflow.
The declaration of `edge2' can be reached with `edge1 == NULL' and
`axis->edges == 0' which results in undefined behaviour.

after checking `axis->num_edges > 1'.  `edge1 != NULL' can be assumed.

Alexei Podtelezhnikov a7f276a281 [autofit] Make autohint warping NORMAL option.
This moves warping option from LIGHT to NORMAL mode.  This makes LIGHT
truly void of hinting in x-direction, with left side bearing never
changed and right side bearing only altered by advance rounding.
Therefore, LIGHT is now ready to return fractional advance.  As a
NORMAL option, warping substitutes normal hinting.

2017-04-27 13:02:24 +02:00
Werner Lemberg 5aa6716a5e Add new `slight' auto-hinting mode.
This mode uses fractional advance widths and doesn't scale glyphs
horizontally, only applying vertical scaling and hinting.

At the same time, the behaviour of the `light' auto-hinter gets
restored for backwards compatibility: Both vertical and horizontal
scaling is again based on rounded metrics values (this was changed
in a commit from 2017-03-30 as a side effect).  To be more precise,
the behaviour is restored for TrueType fonts only; for other font
formats like Type 1, this is a new feature of the `light' hinting
mode.

* include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.
(FT_RENDER_MODE_SLIGHT): New render mode.

* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add

The interface to ftgrid was broken in the series of commits starting
with

  [autofit] Allocate AF_Loader on the stack instead of AF_Module.

from 2015-01-14.

* src/autofit/afmodule.c (_af_debug_hints_rec) [FT_DEBUG_AUTOFIT]:
Use a global AF_GlyphHintsRec object for debugging.
(af_autofitter_done, af_autofitter_load_glyph): Updated.

This avoids one malloc per load.

* src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to

Update prototype.

* src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints'
parameter instead of `FT_Memory'.
(af_loader_done): Directly reset `load_hints'.
(af_loader_load_g): Updated.

* src/autofit/afmodule.c (af_autofitter_load_glyph): Use local

2015-01-14 19:16:12 +01:00
Behdad Esfahbod a4117fbda7 [autofit] Reuse slot glyph loader.
No need to create a new glyph loader; we can reuse the one from
`slot->internal->loader'.  It's hard to tell why it was written that
way originally, but new code looks sound and correct to me, and
avoids lots of allocations.

* src/autofit/afloader.c (af_loader_init): Change return type to
`void'.
Don't call `FT_GlyphLoader_New'.
(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
(af_loader_load_g): Update code to use `internal->loader', which
doesn't need copying of data.

* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
Update prototype.

* src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.
2015-01-14 19:07:54 +01:00
Behdad Esfahbod ae6699f86c [autofit] Remove (unused) support for composite glyphs.
We never have to deal with composite glyphs in the autohinter, as
those will be loaded into FORMAT_OUTLINE by the recursed
`FT_Load_Glyph' function.

In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
FT_LOAD_NO_HINTING:

  /* resolve load flags dependencies */

  if ( load_flags & FT_LOAD_NO_RECURSE )
    load_flags |= FT_LOAD_NO_SCALE         |
                  FT_LOAD_IGNORE_TRANSFORM;

  if ( load_flags & FT_LOAD_NO_SCALE )
  {
    load_flags |= FT_LOAD_NO_HINTING |
                  FT_LOAD_NO_BITMAP;

    load_flags &= ~FT_LOAD_RENDER;
  }

and as such the auto-hinter is never called.  Thus, the recursion in
`af_loader_load_g' never actually happens.  So remove the depth
counter as well.

* src/autofit/afloader.c (af_loader_load_g): Remove `depth'
parameter.
<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
(af_loader_load_glyph): Updated.
2015-01-14 18:55:39 +01:00
Behdad Esfahbod 89bc8d4de7 [autofit] Allocate AF_Loader on the stack instead of AF_Module.
Stop sharing a global `AF_Loader'.  Allocate one on the stack during
glyph load.

Right now this results in about 25% slowdown, to be fixed in a
following commit.

With this patch loading glyphs from different faces from different
threads doesn't immediately crash in the autohinting loader code.
