preferences. The header freetype.h is not now affected, the interface is
specified via an FT_Parameter, the pointer to the interface is hidden in an
internal part of the face record, and all the definitions are in ftincrem.h.
development forum: "If FT_CONFIG_OPTION_INCREMENTAL is undefined
(this is the default), the TrueType loader crashes in line 852 of
src/truetype/ttgload.c when it tries to access face->glyph_locations.".
sfnt_dir_check now ignores the tables 'glyx' and 'locx' which are hacked-out
versions of 'glyf' and 'loca' in some PostScript Type 42 fonts, and will
generally be invalid.
the SFNT loader to check for SFNT-based font files differently. We now
ignore the range "helper" fields and check the "head" table's magic
number instead.
src/psaux/psobjs.c, src/type1/t1load.c, src/type1/t1tokens.h:
fixing a bug in the Type 1 loader that prevented valid font bounding
boxes to be loaded from multiple master fonts.
to support charmaps for CFF fonts
* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c,
src/cff/cffobjs.h, src/cff/cffparse.c, src/cffparse.h, src/cff/cffgload.c,
src/cff/cffgload.h: adding support for CFF charmaps, reformatting the
sources, and removing some bugs in the Encoding and Charset loaders
* src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c
(ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): changed the
syntax of the FT2_DEBUG environment variable used to control debugging
output (i.e. logging and error messages). It must now look like:
any:6 memory:4 io:3 or
any:6,memory:4,io:3 or
any:6;memory:4;io:3
freetype/internal/ftobjs.h, freetype/internal/psaux.h,

src/cff/cffgload.c, src/pshinter/pshalgo1.h, src/pshinter/pshalgo1.c,
src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.h,
src/pshinter/pshalgo3.c: Adding support for hinter-specific bit flags,
and the new FT_Set_Hint_Flags high-level API
incorrect advances when the outline resolution was different from the
metrics resolution
* src/autohint/ahhint.c: removing compiler warnings
* src/autohint/ahglyph.c: slight improvements to the serif detection
code. More work is needed though..
* src/autohint/ahglobal.c, src/autohint/ahtypes.h, src/autohint/ahhint.c:
small improvements to the automatic hinter. un-even stem-widths have now
disappeared and everything looks much better, even if there are still
issues with serifed fonts.
(t1_face_check_cast): Removed.
(FT_Get_PS_Font_Info): Make it work with CID and Type 42 drivers
also.
* src/type42/t42parse.c (t42_parse_sfnts): Fix compiler warning.
t1_cmap_custom_char_next): Fix index computation -- indices start
with 0 and not with cmap->first.
Provide default charmaps.
* src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdriver.c
(PCF_Face_Init), src/pfr/pfrobjs.c (pfr_face_init),
src/type1/t1objs (T1_Face_Init), src/winfonts/winfnt.c
(FNT_Face_Init): Implement it.
* builds/unix/install.mk (install, uninstall): Handle it.
Fix glyph indices for PFR driver.
* src/pfr/pfrcmap.c (pfr_cmap_char_index, pfr_cmap_char_next):
Increase return value by 1.
* src/pfr/pfrobjs.c (pfr_slot_load): Decrease index by 1.
* src/bdf/bdfdrivr.c (bdf_cmap_init): Don't decrease
cmap->num_encodings.
(bdf_cmap_char_index, bdf_cmap_char_next, BDF_Get_Char_Index):
Increase result by 1 for normal cases.
(BDF_Glyph_Load): Decrease index by 1.
* src/pcf/pcfdriver.c (pcf_cmap_char_index, pcf_cmap_char_next,
PCF_Char_Get_Index): Increase result by 1 for normal cases.
(PCF_Glyph_Load): Decrease index by 1.
* src/pcf/pcfread.c (pcf_get_encodings): Don't decrease j for
allocating `encoding'.
* src/base/ftobjs.c (FT_Load_Glyph, FT_Get_Glyph_Name): Fix
bounding tests.
* src/bdf/bdfdrivr.c (BDF_CMapRec) [FT_CONFIG_OPTION_USE_CMAPS]:
New structure.
(bdf_cmap_init, bdf_cmap_done, bdf_cmap_char_index,
bdf_cmap_char_next) [FT_CONFIG_OPTION_USE_CMAPS]: New functions.
(BDF_Get_Char_Index) [!FT_CONFIG_OPTION_USE_CMAPS]: Use only
conditionally.
(BDF_Face_Init): Handle `AVERAGE_WIDTH' and `POINT_SIZE' keywords.
Implement new cmap handling.
(bdf_driver_class): Updated.
* src/sfnt/ttload.c, src/bdf/bdflib.c: removing compiler warnings
* src/type42/t42objs.c: removed the bug that prevented un-hinted
outlines to be loaded
src/base/ftobjs.c, src/objs/fttype1.c, src/sfnt/ttcmap0.c,
src/smooth/ftgrays.c: changed uses of "setjmp" and "longjmp"
to "ft_setjmp" and "ft_lonjmp". Removed direct references to
<stdio.h> and <setjmp.h> when appropriate, to eventually replace
them with a FT_CONFIG_STANDARD_LIBRARY_H. Useful for the XFree86
Font Server backend based on FT2.
- fixed the infamous bug that caused the cache to crash with large fonts.
the hash table buckets array wasn't shrinked correctly during cache
flushes..
src/cache/ftccache.i, src/cache/ftcsbits.c: adding various
experimental optimisations to the cache manager
* src/type42/t42parse.c: removing duplicate function
src/type42/t42parse.h, src/type42/t42objs.h, src/type42/t42objs.c,
src/type42/type42.c:
updated the Type42 driver by splitting it into several files since
it makes the code easier to read and maintain. Also fixed the bug
that prevented the correct display of fonts with "ftview"
(_bdf_parse_glyphs): Use correct size for allocating
`font->unencoded'.
(bdf_load_font): Free array conditionally.
Return proper error code in case of failure.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Make it more robust against
unusual fonts.
amiga/include/freetype/config/ftmodule.h: Updated to include
support for BDF and Type42 drivers.
* docs/modules.txt: Updated.
* src/bdf/bdflib.c (_bdf_parse_glyphs): Replace floating point math
with calls to `FT_MulDiv'.
FT_Get_X11_Font_Format to return an X11-compatible string describing the
font format of a given face. This was put in a new optional base source
file, corresponding to a new public header (named FT_XFREE86_H since
this function should only be used within the XFree86 font server IMO).
* include/freetype/config/ftheader.h: adding FT_XFREE86_H, though it's
not documented yet.
* include/freetype/t1tables.h, src/base/fttype1.c: adding two new APIs
named "FT_Get_PS_Font_Info" and "FT_Has_PS_Glyph_Names". This required
a new optional source in 'src/base' named "fttype1.c"
* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: updating
build control files for the new files "ftxf86.c" and "fttype1.c" in
src/base
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
fixing the SFNT name table loader to support various buggy fonts.
it now ignores empty name entries, entries with invalid pointer
offsets and certain fonts containing tables with broken "storageOffset"
fields.
name strings are now loaded on demand, which reduces the memory
requirements for a given FT_Face tremendously (for example, the
name table of Arial.ttf is about 10Kb and contains 70 names !!)
finally, this is a _quick_ fix. The whole name table loader and
interface will be rewritten in a much more cleanly way shortly,
once CSEH have been introduced in the sources.
FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be
rebuilt from sources. Set macro serial to 1, and use third argument
to AC_DEFINE for our two custom symbols, so ftconfig.in could one day
be rebuilt with autoheader (not recommended now, ftconfig.in is a
custom source file)
(t1_toint): Use it to handle numbers in radix format.
* src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings): Add dummy
for undocumented, obsolete opcode 15.
src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk:
Adding a new API called "FT_Get_BDF_Charset_ID" to retrieve
BDF-specific strings from a face. This is much cleaner
than accessing the internal types "BDF_Public_Face" defined in
FT_INTERNAL_BDF_TYPES_H
* src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdriver.c,
src/truetype/ttdriver.c, src/type1/t1driver.c,
src/winfonts/winfnt.c, src/type42/t42drivr.c, src/bdf/bdfdrivr.c
[FT_CONFIG_OPTION_DYNAMIC_DRIVERS]: Completely removed. It has
been never used.
(parse_font_matrix): Remove unnecessary code.
(parse_sfnts): Initialize some variables.
(t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use
ft_module_driver_has_hinter conditionally.
Moved some type 42 specific structure definitions to...
* include/freetype/internal/t42types.h: New file.
* include/freetype/internal/internal.h (FT_INTERNAL_T42_TYPES_H):
New macro.
* include/freetype/cache/ftcsbits.h (FTC_SBit): Added a new field
`num_grays' for specifying the number of used gray levels.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.
Adding a driver for BDF fonts written by Francesco Zappa Nardelli
<Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to
better adapt it to FreeType, removing unneeded stuff. Additionally,
it now supports Mark Leisher's BDF extension for anti-aliased
bitmap glyphs with 2 and 4 bpp.
* src/bdf/*: New driver.
* include/freetype/internal/bdftypes.h: New file.
* include/freetype/internal/fttrace.h: Added BDF driver components.
* include/freetype/fterrdef.h: Added error codes for BDF driver.
* include/freetype/config/ftmodule.h, src/Jamfile: Updated.
* include/freetype/internal/internal.h (FT_INTERNAL_BDF_TYPES_H):
New macro.
* include/freetype/config/ftstdlib.h (ft_sprintf): New alias for
sprintf.
* include/freetype/internal/fttrace.h: Added Type 42 driver
component.
* src/type42/t42drivr.c: Use it.
* include/freetype/internal/internal.h (FT_INTERNAL_PCF_TYPES_H):
New macro.
