Werner Lemberg 2df73b397d [sfnt] Fix charmap type 2 iterator (#52646).
The subsetted demo font of the report that exhibits the bug has a
very unusual type 2 cmap for Unicode(!): It contains only two
sub-headers, one for one-byte characters (covering the range 0x20 to
0xFA), and a second one for higher byte 0x01 (just for character
code U+0131).

Before this commit, the iterator wasn't able to correctly handle a
sub-header for higher byte 0x01.

* src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment
for outer loop.

Werner Lemberg 286b0c9f33 Fix `make setup dos', second try (#52622).
* builds/detect.mk (dos_setup): Don't use literal `>' character at
all.  Mixing the different escaping rules from make, dos, and
windows is too fragile.
2017-12-09 09:41:45 +01:00
Werner Lemberg ea68f1c8d3 [docmaker] Fix code section parsing.
Stuff like

  {
    <bla>
  }

confused the parser, which incorrectly treated `<bla>' as a markup
tag.

* src/tools/docmaker/content.py (ContentProcessor::process_content):
Apply `re_markup_tags' only outside of code sections.
2017-12-08 20:15:15 +01:00
Werner Lemberg 98ba0c4a37 New `ftdriver.h' file, covering all driver modules.
This reduces redundancy and increases synergy; it also reduces the
number of header files.

2017-11-28 12:43:45 +01:00
Werner Lemberg 40db4a9954 Allow (again) encoding vectors with more than 256 elements (#52464).
In version 2.6.1, this has been disallowed to better reject
malformed fonts; however, this restriction was too strong.  This
time, we only take the first 256 elements into account, since
encoding arrays are always accessed with a 8bit integer, according
to the PostScript Language Reference.

* src/type1/t1load.c (parse_encoding): Implement it.
2017-11-27 22:17:41 +01:00
Jan Alexander Steffens (heftig) 7d81ba7e17 Fix last commit (#52522).
* builds/freetype.mk: Set `FT_OPTION_H' and `FTOPTION_FLAG'

2017-11-27 07:15:04 +01:00
Werner Lemberg 8f4851997b [unix] Install a massaged `ftoption.h' file (#51780).
* builds/unix/configure.raw (ftoption_set, ftoption_unset): New
auxiliary functions to construct...
(FTOPTION_H_SED): ... this new variable.
Apply it as a sed argument while copying `ftoption.h' to the
`builds/unix' directory (using `AC_CONFIG_FILES').
Simplify code of test that checks cpp's computation of bit length
(the test previously created an empty `ftoption.h' file and deleted
it immediately afterwards); without this change, it can happen on my
GNU/Linux box that `configure's execution of `config.status' doesn't
create `ftoption.h' (no idea why this happens).

* builds/unix/install.mk (install): Install
`builds/unix/ftoption.h'.

* builds/unix/unix-def.in (DISTCLEAN): Updated.

* builds/unix/.gitignore: Updated.

Werner Lemberg 0d0e5bb1e6 Minor. 2017-11-23 20:42:57 +01:00
Tor Andersson 2f1863cfb7 Silence unused function warnings.
Some static function declarations cause unused function warnings if
certain config options are turned off via `ftoption.h'.

* src/base/ftbase.h, src/base/ftrfork.c, src/sfnt/ttbdf.h,
src/truetype/ttgxvar.h: Add #ifdef guards around these sections.

Ewald Hew b9bd2d14e2 [psaux] Fix CFF advance widths. (#52466)
Glyph advance widths were being written to the new `PS_Decoder' but not
saved to the underlying format specific decoder. This caused pure CFF
fonts to have bad advance width.

* include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width'
field to pointer.
Remove unused fields.
* src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy
to reference.
Remove unused.
* src/psaux/psft.c (cf2_setGlyphWidth): Update code.

Vlad Tsyrklevich 954710ddd7 * include/freetype/ftrender.h: Fix `FT_Renderer_RenderFunc' type. 2017-11-15 23:06:29 +01:00
Nikolaus Waxweiler a364e38ae7 Use Adobe hinting engine for `light' hinting of both CFF and Type 1.
Since Ewald Hew factored the Adobe hinting engine out of the CFF
driver code, we can now use it on Type 1 (and CID) font formats, as
both have the same hinting philosophy.

This change activates the Adobe hinter when in LIGHT mode, and
therefore always unless explicitly asking for the auto-hinter.  This
makes LIGHT behavior consistent with CFF fonts.  As of this commit,
the hinting engine table looks as follows.

             LIGHT  NORMAL
  -------------------------
   TrueType  Auto   v40
   CFF       Adobe  Adobe
   Type 1    Adobe  Adobe

Ewald Hew cdab9cfae9 [psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251)
The interpreter in Type 1 mode rewinds the charstring after collecting
all hints for building the initial hintmap (commit d52dd7f). However,
some charstrings use `endchar' in a final subroutine call, rewinding to
the start of that subroutine, and only a small section of the actual
glyph is drawn.

* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>:
Ensure we are on the top level charstring before rewinding.

`DFGyoSho-Lt', `DFHSGothic-W5', `DFHSMincho-W3' and `DFHSMincho-W7'.
(tt_check_trickyness_sfnt_ids): Add checksums for DFGothic-EB,
DFGyoSho-Lt, DFHSGothic-W5, DFHSMincho-W3 and DFHSMincho-W7.  Also

Alexei Podtelezhnikov 816516360c [smooth] Fix complex rendering at high ppem.
We used to split large glyphs into horizontal bands and continue
bisecting them still horizontally if that was not enough.  This is
guaranteed to fail when a single scanline cannot fit into the
rendering memory pool.  Now we bisect the bands vertically so that
the smallest unit is a column of the band height, which is guranteed
to fit into memory.

* src/smooth/ftgrays.c (gray_convert_glyph): Implement it.

Alexei Podtelezhnikov 91015cb41d [smooth] Improve complex rendering at high ppem.
At large sizes almost but not exactly horizontal segments can quickly
drain the rendering pool. This patch at least avoids filling the pool
with trivial cells. Beyond this, we can only increase the pool size.

Reported, analyzed, and tested by Colin Fahey.

* src/smooth/ftgrays.c (gray_set_cell): Do not record trivial cells.
