Werner Lemberg 6ab5624330 * src/truetype/ttgload.c (load_truetype_glyph)
[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Call
FT_GlyphLoader_CheckPoints before adding phantom points.  This fixes
a segfault bug with fonts (e.g. htst3.ttf) which have nested
subglyphs more than one level deep.  Reported by Anthony Fok.

* include/freetype/config/ftoption.h: Define
TT_CONFIG_OPTION_BYTECODE_INTERPRETER,
TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING, and
TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING to make it the new
default.

increased root->height by 15% if the line gap was zero.  There exist
fonts (containing e.g. form drawing characters) which intentionally
have a zero line gap value.

Werner Lemberg 26fb1bcd05 * vms_make.com: Reworked support for shareable images on VMS. The
first version was kind of a hack; the current implementation of the

which were created in the previous version.

Further work on creating descrip.mms files on the fly.

Graham Asher 9f36499fa7 Added comment for checkin of unpatented hinting system. 2003-04-25 11:43:07 +00:00
Graham Asher 3ea859f6e9 Added the unpatented hinting system, which is compiled only if
TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined
in ftoption.h
2003-04-25 11:40:46 +00:00
Graham Asher 0798f0c3ec If unpatented hinting is compiled the TrueType face object acquires a
new element, "FT_Bool unpatented_hinting".
2003-04-25 11:36:44 +00:00
Graham Asher 33671d74a2 Added configuration macros (not defined, but in comments) for the
unpatented hinting system.

similar to the PCF driver.
* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
Updated.

* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
is declared twice.  It is perhaps better to modify the zlip source
files directly instead of this hack.
(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
to make build with g++ successful.
2003-04-25 05:35:04 +00:00
David Turner 2dd1e657ba * src/pcf/pcfread.c (pcf_load_font): fixed the computation of
face->num_glyphs, this required increase the value by 1 to respect
        the convention that gindex 0 always corresponds to the "missing
        glyph".
2003-04-24 21:12:18 +00:00
Werner Lemberg 3704aa4525 * builds/unix/unix-cc.in (CFLAGS): Add @CPPFLAGS@. 2003-04-24 06:07:20 +00:00

files first.  Otherwise there are conflicts with FreeType 1
installed simultaneously.
