fonts. Additionally, some entries were handled as `integer' instead
of `number'.

to prevent infinite loop.
* docs/VERSION.DLL: Provide better autoconf snippet to check
FreeType version.
* src/base/ftobjs.c (open_face): Free `internal' not

Mac_Read_sfnt_Resource, IsMacResource, IsMacBinary, load_mac_face)
[!FT_MACINTOSH]: New functions.
(FT_Open_Face) [!FT_MACINTOSH]: Use load_mac_face.
* src/base/ftobjs.c (FT_Load_Glyph): Scale linear advance width only
if FT_FACE_FLAG_SCALABLE is set (otherwise we have a division by
zero since FNT and friends don't define `face->units_per_EM').
* include/freetype/internal/ftobjs.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c,
src/pcf/pcfdriver.c, src/pfr/pfrsbit.c, src/sfnt/ttsbit.c,
src/type42/t42objs.c, src/winfonts/winfnt.c: introduced three new functions
to deal with glyph bitmaps within FT_GlyphSlot objects. these are:
ft_glyphslot_free_bitmap
ft_glyphslot_alloc_bitmap
ft_glyphslot_set_bitmap
these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP
flag manually. the font drivers have been modified to use them as well.
* src/cache/ftlru.c: fixed an invalid assertion check
src/base/ftbdf.c, src/bdf/bdfdrivr.c, src/pcf/pcfdrivr.c,
src/pcf/pcfread.h:
adding a new API, named FT_Get_BDF_Property to retrieve the BDF
properties of a given PCF or BDF font
include/freetype/ftwinfnt.h, src/base/winfnt.c, src/winfonts/winfnt.c,
src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty
bug in the header loader which would cause invalid memory overwrites
* include/freetype/config/ftoption.h, src/autohint/ahglobal.h,
src/autohint/ahglobal.c, src/autohint/ahglyph.c,
src/autohint/ahtypes.h:
included David Chester's patches to the auto-hinter in order to
slightly improve the output. Note that everything is controlled
through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the
end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX
macros to control individual "features".
Note that all improvements are enabled by default, but can be
tweaked for optimization and testing purpose. The configuration
macros will most likely disappear in the short future.
2003-01-11 David Turner <david@freetype.org>
* include/freetype/internal/fnttypes.h: fixed a structure field
definition to avoid memory overwrites
src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
src/gzip/zutil.h: updates to allow compilation without compiler
warnings with LCC-Win32
* include/freetype/freetype.h, docs/VERSION.DLL,
builds/unix/configure.ac: updates for the upcoming 2.1.4 release
* docs/VERSION.DLL: updating document to better explain the differences between
the three version numbers being used on Unix, as well as provide the AutoConf
fragment provided by Lars Clausen
* src/smooth/ftgrays.c (gray_render_conic): fixed small bug that
prevented bezier arcs with negative vertical coordinates to be rendered
appropriately
2002-11-27 Vincent Caron <v.caron@zerodeux.net>
* builds/unix/unix-def.in, builds/unix/freetype-config.in,
builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c:
adding support for system zlib installations when available on the
target platform (Unix only)
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.
2002-11-05 Juliusz <jch@pps.jussieu.fr>
* src/psaux/psobjs.c (ps_table_add): modified increment loop in
order to implement exponential behaviour

src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h:

(it returned invalid values when the outline and metrics resolution
differ)

bitmap-based font formats

(T42_GlyphSlot_Load), src/bdf/bdfdrivr.c (BDF_Glyph_Load): Change
fourth parameter to `FT_Int32'.
* src/pfr/pfrobjs.c (pfr_face_init): Add two missing parameters
and declare them as unused.
* src/cid/cidparse.h (CID_Parser): Use FT_Long for `postscript_len'.
* src/psnames/psnames.h (PS_Unicode_Value_Func): Change return
value to FT_UInt32.

* src/cid/cidgload.c (cid_load_glyph): Add missing cast for
`cid_get_offset'.
* src/psaux/t1decode.c (t1_decoder_parse_charstrings) <18>: Use
cast for `num_points'.
(t1_decoder_init): Use cast for assigning `decoder->num_glyphs'.
* src/base/ftdebug.c (ft_debug_init): Use FT_Int.
* include/freetype/internal/ftdriver.h (FT_Slot_LoadFunc): Use
`FT_Int32' for fourth parameter.
* src/base/ftobjs.c (open_face): Use cast for calling
clazz->init_face.

* src/raster/ftrend1.c (ft_raster1_render): Ditto.
* src/sfnt/sfnt_dir_check: Compare `magic' with unsigned long

include/freetype/ftstroker.h, include/freetype/ftsysio.h,
include/freetype/ftsysmem.h, include/freetype/ttnameid.h:
updating the in-source documentation

DocMaker tool

debug mode of template instantiation

prevent seg fault when hints are provided in an empty glyph !!
* include/freetype/ftimage.h: removed incorrect "zft_" definitions
and updated constants documentation comments

include/freetype/config/ftmodule.h: updated to correctly support
sub-pixel rendering
* include/freetype/cache/ftcimage.h, include/freetype/cache/ftcsbits.h,
src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
rendering correctly. Definition of FTC_ImageTypeRec that replaces the
obsolete FTC_ImageDesc, and has slightly different fields. The
image type is now determined directly by "load_flags" values.
* src/autohint/ahtypes.h, src/autohint/ahhint.c,
src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
to the automatic and Postscript hinters !! and sub-pixel hinting now
works correctly (see demo programs)
ft_encoding_symbol to be FT_ENCODING_MS_SYMBOL (instead of
the erroneous FT_ENCODING_SYMBOL)
* builds/unix/unix-def.in: added "datadir" definition
(thanks to Anthony Fok)
