2003-04-25: Graham Asher <graham.asher@btinternet.com>
Added the optional unpatented hinting system for TrueType. It
allows typefaces which need hinting to produce correct glyph forms
(e.g., Chinese typefaces from Dynalab) to work acceptably without
infringing Apple patents. This system is compiled only if
TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in
ftoption.h.
* include/freetype/ttunpat.h: New file. Defines
FT_PARAM_TAG_UNPATENTED_HINTING.
* include/freetype/config/ftheader.h (FT_TRUETYPE_UNPATENTED_H): New
macro to use when including ttunpat.h.
* include/freetype/config/ftoption.h
(TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING,
TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING): New configuration macros
(not defined, but in comments) for the unpatented hinting system.
* include/freetype/internal/tttypes.h (TT_FaceRec)
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: New element "FT_Bool
unpatented_hinting".
* src/truetype/ttinterp.c (NO_APPLE_PATENT, APPLE_THRESHOLD):
Removed.
(GUESS_VECTOR): New macro.
(TT_Run_Context) [TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]:
Set `both_x_axis'.
(tt_default_graphics_state)
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Updated.
(Current_Ratio) [TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]:
Handle `unpatented_hinting'.
(Direct_Move) [NO_APPLE_PATENT]: Removed.
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Insert assertion.
(Project, FreeProject)
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Insert assertion.
(Compute_Funcs) [TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]:
Implement unpatented hinting.
(DO_SPVTCA, DO_SFVTCA, DO_SPVTL, DO_SFVTL, DO_SPVFS, DO_SFVFS,
Ins_SDPVTL): Call `GUESS_VECTOR'.
(DO_GPV, DO_GFV) [TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]:
Handle `unpatented_hinting'.
(Compute_Point_Displacement) [NO_APPLE_PATENT]: Removed.
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Implement unpatented
hinting.
(Move_Zp2_Point, Ins_SHPIX, Ins_DELTAP, Ins_DELTAC)
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Implement unpatented
hinting.
(TT_RunIns): Updated.
* src/truetype/ttobjs.c
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Include
FT_TRUETYPE_UNPATENTED_H.
(tt_face_init) [TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING,
TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING]: Check
FT_PARAM_TAG_UNPATENTED_HINTING.
* src/truetype/ttobjs.h (TT_GraphicsState)
[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Add `both_x_axis'.
2003-04-25 Werner Lemberg <wl@gnu.org>
* src/bdf/bdflib.c (hash_bucket, hash_lookup): Use `const' for first
argument.
(bdf_get_font_property): Use `const' for third argument.
Updated all callers.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height
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.
2003-04-24 Manish Singh <yosh@gimp.org>
* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Split on `-'
also for searching the style name.
2003-04-24 David Turner <david@freetype.org>
* src/pcf/pcfread.c (pcf_load_font): Fixed the computation of
face->num_glyphs. We must increase the value by 1 to respect the
convention that glyph index 0 always corresponds to the "missing
glyph".
2003-04-24 Werner Lemberg <wl@gnu.org>
* builds/unix/unix-cc.in (CFLAGS): Add @CPPFLAGS@.
2003-04-24 Dieter Baron <dillo@netbsd.org>
* builds/unix/freetype-config.in (cflags): Emit FreeType 2's include
files first. Otherwise there are conflicts with FreeType 1
installed simultaneously.
2003-04-23 Werner Lemberg <wl@gnu.org>
Fixing bugs reported by Nelson Beebe.
* src/base/ftstroker.c (FT_Stroker_ParseOutline): Remove unused

(tt_cmap10_char_next): Remove unused variable `result'
* src/sfnt/sfobjs.c (tt_face_get_name): Mark `error' as unused.
* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Mark `error' as
unused.
* src/type1/t1objs.c (T1_Face_Init): Remove unused variable
`pshinter'.
* src/type1/t1gload.c (T1_Load_Glyph): Use `glyph_data_loaded'
only for FT_CONFIG_OPTION_INCREMENTAL.
2003-04-23 Akito Hirai <akito@kde.gr.jp>
* src/sfnt/ttcmap0.c (tt_cmap4_validate): Provide a weak variant
of the glyph ID bounding check if FT_VALIDATE_TIGHT is not active.
Without this change, many CJK fonts from Dynalab are rejected.
2003-04-23 Joe Marcus Clarke <marcus@FreeBSD.org>
* src/base/ftbdf.c (FT_Get_BDF_Property): Check for valid
`get_interface'.
2003-04-23 Paul Miller <paulm@profoundeffects.com>
* src/base/ftmac.c (parse_fond): Fix handling of style names.
2003-04-23 Werner Lemberg <wl@gnu.org>
* src/pfr/pfrload.c (pfr_extra_item_load_font_id): Use FT_PtrDist
instead of FT_Uint for `len'.
2003-04-22 Werner Lemberg <wl@gnu.org>
* src/gzip/ftgzip.c (zcalloc) [!FT_CONFIG_OPTION_SYSTEM_ZLIB]:
Convert K&R format to modern C usage.
(FT_Stream_OpenGzip): Use long constant.
2003-04-21 Werner Lemberg <wl@gnu.org>
* src/cache/ftccache.c (ftc_cache_lookup): Remove shadow declaration
of `manager'.
2003-04-20 Werner Lemberg <wl@gnu.org>
* doc/INSTALL.UNX: Cleaned up.
2003-04-09 Torrey Lyons <torrey@mrcla.com>
* src/base/ftmac.c (open_face_from_buffer): Removed a double-free
bug that had nasty consequences when trying to open an "invalid"
font on a Mac.
2003-04-09 Mike Fabian <mfabian@suse.de>
* src/bdf/bdfdrivr.h (BDF_encoding_el), src/pcf/pcf.h
(PCF_EncodingRec): Changed FT_Short to FT_UShort in order to be able
to access more than 32768 glyphs in fonts.
2003-04-08 David Turner <david@freetype.org>
* Version 2.1.4 is released.
============================
2003-04-03 Martin Muskens <mmuskens@aurelon.com>
* src/type1/t1load.c (T1_Open_Face): Fixed the code to make it
handle special cases where a font only contains a ".notdef" glyph
(happens in PDF-embedded fonts). Otherwise, FT_Panic was called.
2003-03-27 David Turner <david@freetype.org>
* README: Udpated.
* README.UNX: Removed (now replaced by docs/INSTALL.UNX).
* src/pshinter/pshalgo3.c: The hinter now performs as in 2.1.3 and
will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is
used.
(psh3_dimension_quantize_len): Enabled.
(psh3_hint_align): Enable commented code.
(psh3_hint_align_light): Commented out.
* src/base/ftobjs.c (FT_Set_Char_Size): Changed the default
computations to include rounding in all cases; this is required to
provide accurate kerning data when native TrueType hinting is
enabled.
* src/type1/t1load.c (is_name_char): The Type 1 loader now accepts
more general names according to the PostScript specification (the
previous one was too restrictive).
(parse_font_name, parse_encoding, parse_charstrings, parse_dict):
Use `is_name_char'.
(parse_subrs): Handle empty arrays.
2003-03-20 David Turner <david@freetype.org>
Serious rewriting of the documentation.

Introduced three new functions to deal with glyph bitmaps within
FT_GlyphSlot objects:
ft_glyphslot_free_bitmap
ft_glyphslot_alloc_bitmap
ft_glyphslot_set_bitmap
These functions are much more convenient to use than managing the
FT_GLYPH_OWN_BITMAP flag manually.
* include/freetype/internal/ftobjs.h (ft_glyphslot_free_bitmap,
ft_glyphslot_alloc_bitmap, ft_glyphslot_set_bitmap): New functions.
* src/base/ftobjs.c: Implement them.
(ft_glyphslot_done): Use ft_glyphslot_free_bitmap.
* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdriver.c
(PCF_Glyph_Load): Remove unused variable `memory'.
Use `ft_glyphslot_*' functions.
Don't set `FT_GLYPH_OWN_BITMAP'.
* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Use
`ft_glyphslot_alloc_bitmap'.
* src/sfnt/ttsbit.c (Load_SBit_Image): Change 5th argument to type
`FT_GlyphSlot'.
Adding argument `depth' to handle recursive calls.
Use `ft_glyphslot_alloc_bitmap'.
(tt_face_load_sbit_image): Remove unused variable `memory'.
Don't handle `FT_GLYPH_OWN_BITMAP'.
Update call to Load_SBit_Image.
* src/type42/t42objs.c (ft_glyphslot_clear): Renamed to...
(t42_glyphslot_clear): This. Updated caller.
Call `ft_glyphslot_free_bitmap'.
* src/winfonts/winfnt.c (FNT_Load_Glyph): Use
`ft_glyphslot_set_bitmap'.
Don't handle `FT_GLYPH_OWN_BITMAP'.

crash the cache in rare circumstances (mostly with broken fonts).
2003-03-15 David Turner <david@freetype.org>
* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding
bug. Actually, it seems that previous versions of FreeType didn't
perform TrueType rounding exactly as appropriate.
2003-03-14 David Turner <david@freetype.org>
* src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small
TrueType native rendering glitches; they came from a small rounding
error.
2003-03-13 David Turner <david@freetype.org>
Added new environment variables to control memory debugging with
FreeType. See the description of "FT2_DEBUG_MEMORY",
"FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX" in DEBUG.TXT.
* src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count',
`bound_total', `alloc_total_max', `bound_count', `alloc_count_max'.
(ft_mem_debug_alloc): Handle new variables.
(ft_mem_debug_init): s/FT_DEBUG_MEMORY/FT2_DEBUG_MEMORY/.
Handle new environment variables.
* docs/DEBUG.TXT: Updated.
Fixed the cache sub-system to correctly deal with out-of-memory
conditions.

(pfr_face_init): Fixing compiler warnings.
* src/psaux/psobjs.c (reallocate_t1_table): Fixed a bug (memory
leak) that only happened when a try to resize an array would end in
an out-of-memory condition.
* src/smooth/ftgrays.c (gray_convert_glyph): Removed compiler
warnings / volatile bug.
* src/truetype/ttobjs.c (tt_glyphzone_done): Removed segmentation
fault that happened in tight memory environments.
2003-02-28 Pixel <pixel@mandrakesoft.com>
* src/gzip/ftgzip.c (ft_gzip_file_done): Fixed memory leak: The ZLib
stream was not properly finalized.
2003-02-25 Anthony Fok <anthony@thizlinux.com>
* src/cache/ftccmap.c: Include FT_TRUETYPE_IDS_H.
(ftc_cmap_family_init): The cmap cache now
supports UCS-4 charmaps when available in Asian fonts.
* src/sfnt/ttload.c, src/base/ftobjs.c: Changed "asian" to "Asian"
in comments.
2003-02-25 David Turner <david@freetype.org>
* src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that
caused FreeType to loop endlessly when trying to read certain
compressed gzip files. The following test reveals the bug:
touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz
Several fixes to the PFR font driver:
- The list of available embedded bitmaps was not correctly set in
the root FT_FaceRec structure describing the face.
- The glyph loader always tried to load the outlines when
FT_LOAD_SBITS_ONLY was specified.
- The table loaded now scans for *undocumented* elements of a
physical font's auxiliary data record. This is necessary to
retrieve the "real" family and style names.
NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS!
* src/pfr/pfrload.c (pfr_aux_name_load): New function.
(pfr_phy_font_done): Free `family_name' and `style_name' also.
Remove unused variables.
(pfr_phy_font_load): Extract useful information from the auxiliary
bytes.
* src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL.
(pfr_face_init): Provide fallback values for `family_name' and
`style_name'.
Handle strikes.
(pfr_slot_load): Handle FT_LOAD_SBITS_ONLY.
* src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent',
`descent', `leading', `family_name', and `style_name'.
* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug
when computing the scale factors for a given character size in
points with resolution.
* devel/ft2build.h, devel/ftoption.h: New files (in a new directory)
which are special development versions of include/ft2build.h and
include/freetype/config/ftoption.h, respectively.
2003-02-18 David Turner <david@freetype.org>
Fixing the slight distortion problem that occurred due to the latest
auto-hinter changes.
* src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding.
* src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'.
[!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed.
* src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'.
* src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of
`metrics'.
[FT_CONFIG_CHESTER_ASCENDER]: Code removed.
(Reset_SBit_Size): Fix initialization of `metrics'.
* src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of
`exec->metrics'.
* src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width
"correction" which seemed to provide more trouble than benefits.
2003-02-13 Graham Asher <graham.asher@btinternet.com>
Changed the incremental loading interface in a way that makes it
simpler and allows glyph metrics to be changed (e.g., by adding a
constant, as required by CFF fonts) rather than just overridden.
This was required to make the GhostScript-to-FreeType bridge work.
* src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]:
Allow metrics to be overridden.
* src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]:
Ditto.
* src/truetype/ttgload.c (load_truetype_glyph)
[FT_CONFIG_OPTION_INCREMENTAL]: Simplify.
(compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block
moved down.
* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String)
[FT_CONFIG_OPTION_INCREMENTAL]: Updated.
* include/freetype/ftincrem.h: Updated.
2003-01-31 David Turner <david@freetype.org>
* docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation
for the 2.1.4 release.
* builds/win32/visualc/freetype.dsp,
builds/win32/visualc/index.html: Updating the project file for
2.1.4.
* src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c,
src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c,
src/gzip/infutil.c: Removed old-style (K&R)function definitions.
This avoids warnings with Visual C++ at its most pedantic mode.
* src/pfr/pfrsbit.c: Removed compiler warnings.
* src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR
into an FT_TRACE1 since it caused "ftview" and others to dump too
much junk when trying to display a waterfall with a font without a
Unicode charmap (e.g. SYMBOL.TTF).
Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last
patch from David Chester, but with a much simpler (and saner)
implementation.
* src/autohint/ahhint.c (ah_hinter_load_glyph)
[FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that
the top of non-capital letters is aligned on a pixel boundary
whenever possible.
* src/base/ftobjs.c (FT_Set_Char_Size)
[FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently.
* src/truetype/ttdriver.c (Set_Char_Sizes)
[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only
if this macro is defined.
* src/truetype/ttobjs.c (Reset_Outline_Size)
[FT_CONFIG_CHESTER_ASCENDER]: Round differently.
* src/pshinter/pshalgo3.c: Improved the Postscript hinter. Getting
rid of stem snapping seems to work well here (though the stems are
still slightly moved to increase contrast).
(psh3_dimension_quantize_len): Commented out.
(psh3_hint_align_light): New function.
(psh3_hint_align): Comment out some code.
THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES
STILL SUCK.
2003-01-22 David Chester <davidchester@qmx.net>
* src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the
stem width optimization.

* src/sfnt/ttload.c (sfnt_dir_check): Relaxed the "head" table size
verification to accept a few broken fonts who pad the size
incorrectly (the table should be padded, but its "size" field
shouldn't according to the specification).
2003-01-18 Werner Lemberg <wl@gnu.org>
* builds/unix/ltmain.sh: Regenerated with `libtoolize --force
--copy' from libtool 1.4.3.

2003-01-15 James Su <suzhe@turbolinux.com.cn>
* src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read
certain gzip-ed font files (typo: `&&' -> `&').
2003-01-15 Huw D M Davies <h.davies1@physics.ox.ac.uk>
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/ftheader.h (FT_WINFONTS_H): New macro
for ftwinfnt.h.
* include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H.

* include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to
the type of the first argument to FT_Matrix_Multiply, which isn't
changed -- this adds documentation and convenience.
2003-01-13 Graham Asher <graham.asher@btinternet.com>
* src/sfnt/ttload.c (tt_face_load_metrics)
[FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without
horizontal metrics (without the `hmtx' table) are now tolerated if
an incremental interface has been specified that has a
get_glyph_metrics function, implying that metrics will be supplied
from outside. This happens for certain Type 42 fonts passed from
GhostScript.
2003-01-11 David Chester <davidchester@qmx.net>
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 in "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 purposes. The configuration
macros will most likely disappear in the short future.
* include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_CHESTER_HINTS): New macro.
(FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE})
[FT_CONFIG_OPTION_CHESTER_HINTS]: New macros to control individual
features.
* src/autohint/ahglobal.c (blue_chars) [FT_CONFIG_CHESTER_SMALL_F]:

Increase threshold for `best_dist'.
* src/autohint/ahhint.c (ah_compute_stem_width)
[FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif
handling.
(ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special
version of `ah_compute_stem_width'.
(ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem
alignment when stem widths are less than 1.5 pixels wide centers the
stem slightly off-center of the center of a pixel (this increases
sharpness and consistency).
[FT_CONFIG_CHESTER_SERIF]: Use special version of
`ah_compute_stem_width'.
* src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add
`AH_BLUE_SMALL_F_TOP'.
2003-01-11 David Turner <david@freetype.org>
* include/freetype/internal/fnttypes.h (WinFNT_HeaderRec): Increase
size of `reserved2' to avoid memory overwrites.
2003-01-08 Huw Dawies <huw@codeweavers.com>
* src/winfonts/winfnt.c (winfnt_header_fields): Read 16 bytes into
"reserved2", not "reserved".
* src/base/ftobjs.c (find_unicode_charmap): Fixed the error code
returned when the font doesn't contain a Unicode charmap. This
allows FT2 to load "symbol.ttf" and a few others correctly since the
last release.
(open_face): Fix return value.
2003-01-08 Owen Taylor <owen@redhat.com>
Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and
postscript hinters.

hinter->do_stem_adjust.
(ah_hinter_load_glyph): Set hinter->do_stem_adjust.
* src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add `do_stem_adjust'.
* src/pshinter/pshalgo3.c (psh3_hint_align): Use `do_stem_adjust'.
(ps3_hints_apply): Handle FT_RENDER_MODE_LIGHT.
* include/freetype/freetype.h (FT_Render_Mode): Add
FT_RENDER_MODE_LIGHT.
* src/truetype/ttgload.c: Fixing the TrueType loader to handle
invalid composites correctly by limiting the recursion depth.
(TT_MAX_COMPOSITE_RECURSE): New macro.
(load_truetype_glyph): Add argument `recurse_count'.
Load a composite only if the numbers of contours is -1, emit error
otherwise.
(TT_Load_Glyph): Updated.
2003-01-08 David Turner <david@freetype.org>
* Jamrules, Jamfile, Jamfile.in, src/*/Jamfile: Small changes to
support the compilation of FreeType 2 as part of larger projects
with their own configuration options (only with Jam).
2003-01-07 David Turner <david@freetype.org>
* src/base/ftstroker.c: Probably the last bug-fixes to the stroker;
the API is likely to change, however.
(ft_stroke_border_close): Don't record empty paths.
(ft_stroke_border_get_counts): Increase `num_points' also in for loop.
(ft_stroke_border_export): Don't increase `write' twice in for loops.
(ft_stroker_outside): Handle `phi' together with `theta'.
(FT_Stroker_ParseOutline): New function.
* src/base/fttrigon.c (FT_Angle_Diff): Fixing function: It returned
invalid values for large negative angle differences (resulting in
incorrect stroker computations, among other things).
* src/cache/ftccache.c (ftc_node_hash_unlink): Removing incorrect
assertion, and changing code to avoid hash table size contraction.
* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Adding

differences between the three version numbers being used on Unix, as
well as providing an 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.
2002-12-02 Antoine Leca <Antoine-Freetype@Leca-Marti.org>
* src/base/ftobjs.c: Modified the logic to get Unicode charmaps.
Now it loads UCS-4 charmaps when there is one.
(find_unicode_charmap): New function.
(open_face): Refer to the above one.
(FT_Select_Charmap): Idem.
2002-11-29 Antoine Leca <Antoine-Freetype@Leca-Marti.org>
* include/freetype/ftgzip.h: Correct the name of the controlling
macro (was __FTXF86_H__ ...).
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
[FT_CONFIG_OPTION_SYSTEM_ZLIB]: Adding support for system zlib
installations if available on the target platform (Unix only).
2002-11-23 David Turner <david@freetype.org>
* src/cff/cffload.c (cff_charset_load, cff_encoding_load): Modified
charset loader to accept pre-defined charsets, even when the font
contains fewer glyphs. Also enforced more checks to ensure that we
never overflow the character codes array in the encoding.
2002-11-22 Antoine Leca <Antoine-Freetype@Leca-Marti.org>
* include/freetype/ttnameid.h: Updated to latest OpenType
specification.
2002-11-18 David Turner <david@freetype.org>
* Version 2.1.3 is released.
============================
2002-11-07 David Turner <david@freetype.org>
* src/cache/ftcsbit.c (ftc_sbit_node_load): Fixed a small bug that
caused problems with embedded bitmaps.
* src/otlayout/otlayout.h, src/otlyaout/otlconf.h,
src/otlayout/otlgsub.c, src/otlayout/otlgsub.h,
src/otlayout/otlparse.c, src/otlayout/otlparse.h,
src/otlayout/otlutils.h: Updating the OpenType Layout code, adding
support fot the first GSUB lookups. Nothing that really compiles
for now though.
* src/autohint/ahhint.c (ah_align_serif_edge): Disabled serif stem
width quantization. It produces slightly better shapes though this
is not distinguishable with many fonts.
Remove other dead code.
* src/Jamfile, src/*/Jamfile: Simplified.
Use $(FT2_SRC_DIR).
2002-11-06 David Turner <david@freetype.org>
* include/freetype/freetype.h (FT_LOAD_TARGET_LIGHT): New macro.
(FT_LOAD_TARGET, FT_LOAD_TARGET_MODE): Use `& 15' instead of `& 7'.
2002-11-05 David Turner <david@freetype.org>
* 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 as a volatile
pointer to a variable :-)
The fix was to change
`volatile FT_Byte* p'
into
`FT_Byte* volatile p'.
* src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c
(pfr_get_metrics), 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.

differ).
* include/freetype/ftpfr.h, include/freetype/internal/pfr.h: New
files.
* include/freetype/internal/internal.h (FT_INTERNAL_PFR_H): New

* src/pfr/pfrobjs.c: Remove dead code.
* src/base/ftobjs.c (ft_glyphslot_clear): Small internal fix to
better support bitmap-based font formats.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Fix handling of
`scale'.
Fix arguments to `FT_Vector_From_Polar'.
2002-10-31 David Turner <david@freetype.org>

src/pcf/pcf.h (PCF_FaceRec): Add `gzip_stream' and `gzip_source'.
* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_ZLIB):
New macro.
(T1_CONFIG_OPTION_DISABLE_HINTER, FT_CONFIG_OPTION_USE_CMAPS
FT_CONFIG_OPTION_NO_CONVENIENCE_FUNCS,
FT_CONFIG_OPTION_ALTERNATE_GLYPH_FORMATS): Removed.
(FT_EXPORT, FT_EXPORT_DEF, FT_DEBUG_LEVEL_ERROR,
FT_DEBUG_LEVEL_TRACE, FT_DEBUG_MEMORY): Comment out definitions so
that platform specific configuration file can override.
* include/freetype/internal/ftstream.h: Include FT_SYSTEM_H.
2002-10-30 David Turner <david@freetype.org>
* FreeType 2.1.3rc3 released.
2002-10-25 David Turner <david@freetype.org>
* include/freetype/ftcache.h (FT_POINTER_TO_ULONG): New macro.
(FTC_FACE_ID_HASH): Rewritten, using FT_POINTER_TO_ULONG.

2002-10-07 Werner Lemberg <wl@gnu.org>
* include/freetype/freetype.h (FT_Open_Face): Use `const' for `args'
(suggested by Graham).

(ft_input_stream_new): Ditto.
2002-10-05 David Turner <david@freetype.org>
Adding support for embedded bitmaps to the PFR driver, and rewriting
its kerning loader/handler to use all kerning pairs in a physical
font (and not just the first item).
* src/pfr/pfr.c: Include `pfrsbit.c'.
* src/pfr/pfrgload.c: Include `pfrsbit.h'.
* src/pfr/pfrload.c (pfr_extra_item_load_kerning_pairs): Rewritten.
(pfr_phy_font_done, pfr_phy_font_load): Updated.

src/tools/docmaker/tohtml.py: Fixing a few nasty bugs.
* src/sfnt/ttcmap0.c (tt_cmap4_validate): The validator for format 4
sub-tables is now capable of dealing with invalid "length" fields at
the start of the sub-table. This allows fonts like "mg______.ttf"
(i.e. Marriage) to return accurate charmaps.
* docs/CHANGES: Updated.
2002-10-05 Werner Lemberg <wl@gnu.org>
* src/smooth/ftgrays.c (SUBPIXELS): Add cast to `TPos'.

Anthony Fok).
2002-08-29 David Turner <david@freetype.org>
Slight modification to the Postscript hinter to slightly increase
the contrast of smooth hinting. This is very similar to what the
auto-hinter does when it comes to stem width computations. However,
it produces better results with well-hinted fonts.

* src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add flags to control
vertical and horizontal hints and snapping.
* README, docs/CHANGES: Updating for the 2.1.3 release.
2002-08-27 David Turner <david@freetype.org>
* Massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all
logical transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE,
#with define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c,
src/smooth/ftsmooth.c, include/freetype/ftimage.h: Adding support
for LCD-optimized rendering though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
This is still work in progress, don't expect everything to work
correctly though most of the features have been implemented.
* Adding new FT_LOAD_XXX flags, used to specify both hinting and
rendering targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated
hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated
hinting & rendering
Note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.

* docs/VERSION.DLL: New file.
2002-08-23 Graham Asher <graham.asher@btinternet.com>
* src/cff/cffgload.c (cff_operator_seac)
[FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not
incremental in the case of CFF but just using callbacks to get glyph
recipes) pass the character code, not the glyph index, to the
get_glyph_data function; they have no valid charset table.
* src/cff/cffload.c (cff_font_load): Removed special cases for
FT_CONFIG_OPTION_INCREMENTAL, which are no longer necessary; CFF
fonts provided via the incremental interface now have to conform
more closely to the CFF font format.
* src/cff/cffload.h (cff_font_load): Removed argument now unneeded.
* src/cff/cffobjs.c (cff_face_init): Changed call to cff_font_load
to conform with new signature.

* src/pshinter/pshalgo3.c (psh3_glyph_compute_inflections,
psh3_glyph_compute_extrema, psh3_hint_table_find_strong_point): Fix
compiler warnings and resolve shadowing of local variables.
2002-08-21 David Turner <david@freetype.org>
The automatic and Postscript hinter now automatically detect
inflection points in glyph outlines and treats them specially. This
is very useful to prevent nasty effect like the disappearing
diagonals of "S" and "s" in many, many fonts.
* src/autohint/ahtypes.h (ah_flag_inflection): New macro.
* src/autohint/ahangles.c (ah_angle_diff): New function.
* src/autohint/ahangles.h: Updated.
* src/autohint/ahglyph.c (ah_outline_compute_inflections): New
function.

src/tools/docmaker/tohtml.py: Updating the DocMaker tool.
* include/freetype/freetype.h: Changing the type of the "load_flags"
parameter from "FT_Int" to "FT_Int32", this in order to support more
options. This should only break binary and/or source compatibility
on 16-bit platforms (Atari?).

* src/base/ftobjs.c (FT_Load_Glyph): Updated.
Handle FT_LOAD_NO_AUTOHINT.

src/autohint/ahmodule.c [DEBUG_HINTER]: Removing compiler warnings
(only used in development builds anyway).
Improve support of local extrema and stem edge points.
* src/pshinter/pshalgo3.h (PSH3_Hint_TableRec): Use PSH3_ZoneRec
for `zones'.
(PSH3_DIR_UP, PSH3_DIR_DOWN): Exchange values.

horiBearingY.
2002-08-16 George Williams <gww@silcom.com>
Add support for Apple composite glyphs.

* src/truetype/ttgload.c (OVERLAP_COMPOUND, SCALED_COMPONENT_OFFSET,
UNSCALED_COMPONENT_OFFSET): New macros for additional OpenType
glyph loading flags.
(load_truetype_glyph): Implement it.
2002-08-16 Werner Lemberg <wl@gnu.org>
* src/cff/cffgload.c (cff_free_glyph_data),
src/cff/cffload.c (cff_font_load): Use FT_UNUSED.
2002-08-15 Werner Lemberg <wl@gnu.org>
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Initialize `error'.
* src/sfnt/sfobjs.c (SFNT_Load_Face): Fix compiler warning.
2002-08-15 Graham Asher <graham.asher@btinternet.com>
Implemented the incremental font loading system for the CFF driver.
Tested using the GhostScript-to-FreeType bridge (under development).
* src/cff/cffgload.c (cff_get_glyph_data, cff_free_glyph_data): New
functions.
(cff_operator_seac, cff_compute_max_advance, cff_slot_load): Use
them.
* src/cff/cffload.c (cff_font_load): Add `face' parameter.
Load charset and encoding only if there are glyphs.
[FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts don't need
character recipes.
* src/cff/cffload.h, src/cff/cffobjs.c: Updated.
* src/cid/cidgload.c (cid_load_glyph)
[FT_CONFIG_OPTION_INCREMENTAL]: Corrected the incremental font
loading implementation to use the new system introduced on
2002-08-01.
2002-08-06 Werner Lemberg <wl@gnu.org>
* src/cff/cffcmap.c: Remove compiler warnings.

* src/raster/ftraster.c: s/wait/waiting/.
2002-08-01 Graham Asher <graham.asher@btinternet.com>
* src/type1/t1load.c (T1_Open_Face): Tolerate a face with no
charstrings if there is an incremental loading interface. Type 1
faces supplied by PostScript interpreters like GhostScript will
typically not provide any charstrings at load time, so this is
essential if they are to work.
2002-08-01 Graham Asher <graham.asher@btinternet.com>
Modified incremental loading interface to be closer to David's
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.
* include/freetype/freeetype.h [FT_CONFIG_OPTION_INCREMENTAL]:
Removed.
* include/freetype/internal/ftobjs.h [FT_CONFIG_OPTION_INCREMENTAL]:
Include FT_INCREMENTAL_H.

[FT_CONFIG_OPTION_INCREMENTAL]: Updated.
* src/sfnt/sfobjs.c (SFNT_Load_Face) [FT_CONFIG_OPTION_INCREMENTAL]:
Updated.

* src/truetype/ttobjs.c: Fix for bug reported by Sven Neumann
[sven@gimp.org] on the FreeType 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."
2002-07-18 Graham Asher <graham.asher@btinternet.com>
Added types and structures to support incremental typeface loading.
The FT_Incremental_Interface structure, defined in freetype.h, is
designed to be passed to FT_Open_Face to provide callback functions
to obtain glyph recipes and metrics, for fonts like those passed
from PostScript that do not necessarily provide all, or any, glyph
information, when first opened.

New configuration macro to enable incremental face loading. By
default it is not defined.

They provide a new API (FT_Get_X11_Font_Format) to retrieve 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 (FT_XFREE86_H): New macro (not
documented yet).

with calls to `FT_MulDiv'.
2002-05-28 David Turner <david@freetype.org>
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).
This is a temporary 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.
* include/freetype/internal/tttypes.h (TT_NameEntryRec): Change
type of `stringOffset' to FT_ULong.
(TT_NameTableRec): Change type of `numNameRecords' and
`storageOffset' to FT_UInt.
Replace `storage' with `stream'.
* src/base/ftnames.c (FT_Get_Sfnt_Name): Load name on demand.
* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Ditto.
Make code more robust.
* src/sfnt/sfobjs.c (TT_NameEntry_ConvertFunc): New typedef.
(tt_face_get_name): Use it.
Make code more robust.
* src/sfnt/ttload.c (TT_Load_Names): Use `static' for arrays.
Handle invalid `storageOffset' data better.
Set length fields to zero for invalid or ignored data.
Remove code within FT_DEBUG_LEVEL_TRACE.
(TT_Free_Names): Updated.
2002-05-24 Tim Mooney <enchanter@users.sourceforge.net>
* builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and
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)
2002-05-22 Werner Lemberg <wl@gnu.org>
* include/freetype/config/ftheader.h (FT_BEZIER_H): Removed.

bug that prevented FreeType 2.x and FreeType 1.x to produce
bit-by-bit identical monochrome glyph bitmaps with native TrueType
hinting. The culprit was a single-bit flag that wasn't set
correctly by the TrueType glyph loader.

tests are still needed).
* include/freetype/internal/ftobjs.h, src/sfnt/Jamfile,
src/sfnt/rules.mk, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h: Updated
the SFNT charmap support to use FT_CMaps.
* include/freetype/fterrdef.h: New file.
* include/freetype/fterrors.h: Include it. It contains all error
codes.
* include/freetype/config/ftheader.h (FT_ERROR_DEFINITIONS_H): New
macro.

Changed the names of memory macros. Examples:
MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
MEM_Move => FT_MEM_MOVE
ALLOC => FT_ALLOC
FREE => FT_FREE
REALLOC = >FT_REALLOC
FT_NEW was introduced to allocate a new object from a _typed_
pointer.
Note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by
FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
arguments.
This results in _lots_ of sources being changed, but makes the code
more generic and less error-prone.

src/sfnt/ttsbit.c, src/truetype/ttgload.c, src/truetype/ttpload.c,
src/winfonts/winfnt.c: Changed the definitions of stream macros.
Examples:
NEXT_Byte => FT_NEXT_BYTE
NEXT_Short => FT_NEXT_SHORT
NEXT_UShortLE => FT_NEXT_USHORT_LE
READ_Short => FT_READ_SHORT
GET_Long => FT_GET_LONG
etc.
Also introduced the FT_PEEK_XXXX functions.
* src/cff/cffobjs.c (CFF_Build_Unicode_Charmap): Removed commented
out function.
(find_encoding): Removed.
(CFF_Face_Init): Remove charmap support.
* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_CMAPS,
TT_CONFIG_CMAP_FORMAT{0,2,4,6,8,10,12}): New macros to fine-tune
support of cmaps.

src/type1/t1cmap.c: Updating and moving the Type 1 FT_CMap support
from "src/type1" to "src/psaux" since it is going to be shared by
the Type 1 and CID font drivers.
* src/psaux/Jamfile, src/psaux/psaux.c, src/psaux/psauxmod.c,
src/psaux/rules.mk, include/freetype/internal/psaux.h: Added support
for Type 1 FT_CMaps.
2002-03-20 David Turner <david@freetype.org>
* src/base/ftgloadr.c (FT_GlyphLoader_CheckSubGlyphs): Fixed a
memory allocation bug that was due to un-careful renaming of the
FT_SubGlyph type.
* src/base/ftdbgmem.c (ft_mem_table_destroy): Fixed a small bug that
caused the library to crash with Electric Fence when memory
debugging is used.

* src/base/ftinit.c (FT_Init_FreeType): Updated.
2002-03-06 Werner Lemberg <wl@gnu.org>
* src/pshinter/pshglob.h (PSH_DimensionRec): s/std/stdw/.

2002-03-05 David Turner <david@freetype.org>
* src/type1/t1objs.c (T1_Face_Init), src/cff/cffobjs.c
(CFF_Face_Init), src/cid/cidobjs.c (CID_Face_Init): Removing the bug
that returned global BBox values in 16.16 fixed format (instead of
integer font units).
* src/cid/cidriver.c (cid_get_postscript_name): Fixed a bug that
caused the CID driver to return Postscript font names with a leading
slash ("/") as in "/MOEKai-Regular".
* src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name),
src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so
that it accepts broken fonts like "foxjump.ttf", which made FreeType
crash when trying to load them.
Also improved the name table parser to be able to load
Windows-encoded entries before Macintosh or Unicode ones, since it
seems some fonts don't have reliable values here anyway.
* include/freetype/internal/psnames.h: Add typedef for
`PSNames_Service'.
2002-03-05 Werner Lemberg <wl@gnu.org>
* builds/unix/aclocal.m4, builds/unix/ltmain.sh: Update to libtool
1.4.2.
Apply a small patch for AIX to make shared libraries work (this
patch is already in the CVS version of libtool).
* builds/unix/config.sub, builds/unix/config.guess: Updated to
recent versions.
* builds/unix/configure.ac: Fix typo
(AC_CONFIG_FILE->AC_CONFIG_FILES).
* builds/unix/configure: Regenerated.
2002-02-28 David Turner <david@freetype.org>
* include/freetype/ftconfig.h: Changed `FT_LOCAL xxxx' to
`FT_LOCAL( xxxx )' everywhere in the source. The same goes for
`FT_LOCAL_DEF xxxx' which is translated to `FT_LOCAL_DEF( xxxxx )'.
* include/freetype/freetype.h (FREETYPE_MINOR, FREETYPE_PATCH):
Changing version to 2.1.0 to indicate an unstable branch.
Added the declarations of FT_Get_First_Char and FT_Get_Next_Char.
* src/base/ftobjs.c: Implement FT_Get_First_Char and
FT_Get_Next_Char.
* include/freetype/t1tables.h: Renaming structure types. This
typedef T1_Struct_
{
} T1_Struct;
becomes
typedef PS_StructRec_
{
} PS_StructRec, *PS_Struct;
typedef PS_StructRec T1_Struct; /* backwards-compatibility */
Hence, we increase the coherency of the source code by effectively
using the `Rec' prefix for structure types.
2002-02-27 David Turner <david@freetype.org>
* src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the
names table loader. Invalid individual name entries are now handled
correctly. This allows the loading of very buggy fonts like
"foxjump.ttf" without allocating tons of memory and causing crashes.
* src/otlayout/otlcommon.h, src/otlayout/otlcommon.c: Adding (still
experimental) code for OpenType Layout tables validation and
parsing.

than one argument correctly. For example, when typing:
./configure --disable-shared --disable-nls
the "--disable-nls" was incorrectly sent to the "make" program.
2002-01-29 Werner Lemberg <wl@gnu.org>
* README.UNX: Fix typo.

2002-01-09 Maxim Shemanarev <mcseemagg@yahoo.com>
* src/smooth/ftgrays.c (gray_render_line): Small optimization to
the smooth anti-aliased renderer that deals with vertical segments.
This results in a 5-7% speedup in rendering speed.

a release build (debugging off, bytecode interpreter off).
* src/base/ftobjs.c, src/base/ftoutln.c, src/cache/ftccmap.c,
src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c,
src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler
warnings (in pedantic compilation modes).
2002-01-05 David Turner <david@freetype.org>
* src/autohint/ahhint.c (ah_align_linked_edge): Modified computation
of auto-hinted stem widths; this avoids color fringes in
"ClearType-like" rendering.
* src/truetype/ttgload.c (TT_Load_Glyph_Header,
TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph):
Modified the TrueType loader to make it more paranoid; this avoids
nasty buffer overflows in the case of invalid glyph data (as
encountered in the output of some buggy font converters).

* src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the
library when dealing with certain weird fonts like "Stalingrad", in
"sadn.pfb" (this font has no full font name entry).
* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):
New function to check the consistency of outline data.
* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to
ensure that loaded glyphs are valid. This allows certain fonts like
"tt1095m_.ttf" to be loaded even though it appears they contain
really funky glyphs.
There still is a bug there, though.
* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.
2001-12-30 David Turner <david@freetype.org>
* src/autohint/ahhint.c (ah_hinter_load): Fix advance width

spacing of letters in KDE and Gnome.
2001-12-25 Antoine Leca <Antoine-Freetype@Leca-Marti.org>

2001-12-22 David Turner <david@freetype.org>
* src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an
incorrect glyph advance in the case of mono-width fonts (like
Courier, Andale Mono, and others).
2001-12-22 Detlef W<>rkner <TetiSoft@apg.lahn.de>
* builds/amiga/*: Adaptations to latest changes.
Support added for MorphOS.
2001-12-22 Werner Lemberg <wl@gnu.org>
* src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'.

* src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter):
Ignore invalid "hintmask" and "cntrmask" operators (instead of
returning an error). Glyph 2028 of the CFF font "MSung-Light-Acro"
couldn't be rendered otherwise (it seems its charstring is buggy,
though this requires more analysis).
(FT_COMPONENT): Define.
* src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c
(T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a
bug where the X and Y axis where inversed in the postscript hinter.
This caused problem when displaying on non-square surfaces.
* src/pshinter/pshalgo2.c: s/vertical/dimension/.
* src/pshinter/pshglob.c (psh_globals_new): Replaced a floating
point constant with a fixed-float equivalent. For some reasons not
all compilers are capable of directly computing a floating pointer
constant casted to FT_Fixed, and will link a math library instead.
2001-12-20 Werner Lemberg <wl@gnu.org>
* src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix
tracing strings.
* src/cache/ftccmap.c (ftc_cmap_family_init): Ditto.

routines were never released when CID faces were destroyed.
* src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: Updated
to move the definition of encoding tables back within "cffload.c"
instead of making them part of a shared header (causing problems in
"multi" builds). This reverts change 2001-08-08.
* docs/CHANGES: Updated for 2.0.6 release.
* docs/TODO: Added "stem3 and counter hints support" to the TODO
list for the Postscript hinter.
* docs/BUGS: Closed the AUTOHINT-NO-SBITS bug.
2001-12-19 David Turner <david@freetype.org>
* include/freetype/cache/ftcache.h: Added comments to indicate that
some of the exported functions should only be used by applications
that need to implement custom cache types.
* src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug
that prevented composites from loading correctly, due to missing
parentheses around macro parameters.

(FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY):
"Fixed" the bug that prevented embedded bitmaps to be loaded when
the auto-hinter is used. This actually is a hack but will be enough
until the internal re-design scheduled for FreeType 2.1.
* src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline
shifting bug in the monochrome renderer.
* README: Updated version numbers to 2.0.6.

(T1_Load_Glyph), src/cid/cidgload.c (CID_Load_Glyph),
src/cff/cffgload.c (CFF_Load_Glyph): Fixed a serious bug common to
all font drivers (the advance width was never hinted when it
should).
* include/freetype/freetype.h (FREETYPE_PATCH): New macro.
* src/base/ftdbgmem.c (debug_mem_dummy) [!FT_DEBUG_MEMORY]: Don't
use `extern' keyword.
2001-12-12 David Turner <david@freetype.org>
* src/pshint/pshglob.c (psh_blues_scale_zones, psh_blues_snap_stem
psh_globals_new): Adding correct BlueScale/BlueShift support, plus
family blues processing.
* src/pshint/pshglob.h (PSH_BluesRec): Updated.
Started adding support for the Postscript hinter in the CFF module.
* src/cff/cffgload.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.
(CFF_Parse_CharStrings): Implement it.
* src/cff/cffgload.h: Updated.
2001-12-12 Werner Lemberg <wl@gnu.org>

2001-12-11 David Turner <david@freetype.org>
* builds/unix/freetype-config.in: Modified the script to prevent
passing "-L/usr/lib" to gcc.
* docs/FTL.TXT: Simple fix (change "LICENSE.TXT" to "FTL.TXT").
* builds/unix/freetype2.m4: New file for checking configure paths.
We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I
didn't modify builds/unix/install.mk yet.
* INSTALL: Updated the instructions to build shared libraries with
Jam. They were simply wrong.
* src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused
slightly improper results for `FT_Cos' and `FT_Sin' (example:
FT_Sin(0) == -1!).
2001-12-11 Detlef W<>rkner <TetiSoft@apg.lahn.de>
* include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE):
Fixed incorrect argument types.
2001-12-10 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr>
* src/pcf/pcfdriver.c (PCF_Init_Face): Allow Xft to use PCF fonts
by setting the "face->metrics.max_advance" correctly.

charmap cache.
* src/cache/ftcache.c: Updated.
* src/autohint/ahhint.c (ah_hinter_hint_edges): s/UNUSED/FT_UNUSED/.
2001-12-06 Leonard Rosenthol <leonardr@lazerware.com>
Added support for reading .dfont files on Mac OS X. Also added a
new routine which looks up a given font by name in the Mac OS and
returns the disk file where it resides.
* src/base/ftmac.c: Include <Files.h> and <TextUtils.h>.
(is_dfont): New auxiliary function.
(FT_New_Face_From_dfont): New function.

2001-12-06 Werner Lemberg <wl@gnu.org>
* INSTALL: Small update.
2001-12-05 David Turner <david@freetype.org>
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Re-ordered code for
debugging purposes.
Comment out use of `origin'.
* src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug
where outline shifting wasn't correctly undone after bitmap
rasterization. This created problems with certain glyphs (like '"'
of certain fonts) and the cache system.
* src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo.
* src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo.
(ps2_hints_apply): Small fix.
2001-12-05 David Turner <david@freetype.org>
* src/pshinter/pshalgo2.c (psh2_hint_table_init),
src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler
warnings.
* include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*:
Yet another massive rewrite of the caching sub-system in order to
both increase performance and allow simpler cache sub-classing. As
an example, the code for the image and sbit caches is now much
simpler.
I still need to update the documentation in
www/freetype2/docs/cache.html to reflect the new design though.
* include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New
macro.
(FT_CACHE_INTERNAL_CACHE_H): Updated.
2001-12-05 David Krause <freetype@davidkrause.com>
* docs/license.txt: s/X Windows/X Window System/.
2001-12-04 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c: Fix definition condition of MEM_Set().
* src/smooth/ftgrays.c (M_Y): Change value to 192.
* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.

and `T1_Size_Done()'.
2001-11-20 Antoine Leca <antoineleca@multimania.com>
* include/freetype/ttnameid.h: Added some new Microsoft language
codes and LCIDs as found in MSDN (Passport SDK). Also added
comments about the meaning of bit 57 of the `OS/2' table
(TT_UCR_SURROGATES) which (with OpenType v.1.3) now means "there is
a character beyond 0xFFFF in this font". Thanks to Detlef W<>rkner
<TetiSoft@apg.lahn.de> for noticing this.
2001-11-20 David Turner <david@freetype.org>
* src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting
routine that created nasty alignment artefacts.
* src/pshinter/pshrec.c, tests/gview.c: Debugging updates.
* src/smooth/ftgrays.c: De-activated experimental gamma support.
Apparently, `optimal' gamma tables depend on the monitor type,
resolution and general karma, so it's better to compute them outside
of the rasterizer itself.
(gray_convert_glyph): Use `volatile' keyword.
2001-10-29 David Turner <david@freetype.org>
Adding experimental `gamma' support. This produces smoother glyphs
at small sizes for very little cost.
* src/smooth/ftgrays.c (grays_init_gamma): New function.
(gray_raster_new): Use it.
Various fixes to the auto-hinter. They merely improve the output of
sans-serif fonts. Note that there are still problems with serifed
fonts and composites (accented characters).
* src/autohint/ahglyph.c (ah_outline_load,
ah_outline_link_segments): Implement it.
Fix typos.
(ah_outline_save, ah_outline_compute_segments): Fix typos.
* src/autohint/ahhint.c (ah_align_serif_edge): New argument
`vertical'. Implement improvement.
(ah_hint_edges_3, ah_hinter_hint_edges): Implement it.
Fix typos.
(ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix
typos.
(ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined.
* src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro.
* src/autohint/ahtypes.h: Ditto.
(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'
(making them global as `ah_debug_disable_horz' and
`ah_debug_disable_vert').
Fix typos.
* tests/gview.c: Updated the debugging glyph viewer to show the
hints generated by the "autohint" module.
2001-10-27 David Turner <david@freetype.org>
* src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that
considerably lowered the performance of the abstract chunk cache.
2001-10-26 David Turner <david@freetype.org>
* include/freetype/ftcache.h, include/freetype/cache/*.h,
src/cache/*.c: Major re-design of the cache sub-system to provide
better performance as well as an "Acquire"/"Release" API. Seems to
work well here, but probably needs a bit more testing.
2001-10-26 Leonard Rosenthol <leonardr@lazerware.com>
* builds/mac/README: Updated to reflect my taking over the project
and that is now being actively maintained.
* src/base/ftmac.c (parse_fond): Applied patches from Paul Miller
<paulm@profoundeffects.com> to support loading a face other than the
first from a FOND resource.
(FT_New_Face_From_FOND): Updated.
2001-10-25 Leonard Rosenthol <leonardr@lazerware.com>
* builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac
OS for latest version (7) of CWPro and for recent changes to the FT
source tree.
2001-10-25 David Turner <david@freetype.org>
* include/freetype/config/ftoption.h: Updated comments to explain
precisely how to use project-specific macro definitions without
modifying this file manually.
(FT_CONFIG_FORCE_INT64): Define.
(FT_DEBUG_MEMORY): New macro.
2001-10-24 Tom Kacvinsky <tkacvins@freetype.org>
* builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'.
2001-10-23 David Turner <david@freetype.org>
* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
Improvements to the memory debugger to report more information in
case of errors. Also, some allocations that occurred through REALLOC
couldn't be previously catched correctly.
* src/autohint/ahglyph.c (ah_outline_compute_segments,
ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),
src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced
liberal uses of memset() by the MEM_Set() macro.
2001-10-23 David Turner <david@freetype.org>
* src/raster/ftraster.c (Update): Removed to be inlined in ...
(Sort): Updated.
2001-10-22 David Turner <david@freetype.org>
* builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory),
builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory),
builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),
src/base/ftdbgmem.c: Updated the memory debugger and
platform-specific implementations of `ftsystem' in order to be able
to debug memory allocations on Unix, VMS and Amiga too!
* src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed
some bogus warnings.
* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
Modified the debugging memory manager to report the location (source
file name + line number) where leaked memory blocks are allocated in
the source file.
* src/base/ftdbgmem.c: New debugging memory manager. You must
define the FT_DEBUG_MEMORY macro in "ftoption.h" to enable it. It
will record every memory block allocated and report simple errors
like memory leaks and double deletes.
* src/base/Jamfile: Include ftdbgmem.
* src/base/rules.mk: Ditto.
* src/base/ftbase.c: Include ftdbgmem.c.
* include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY
macro definition.
* src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the
base component to use the debugging memory manager when the macro
FT_DEBUG_MEMORY is defined.
2001-10-21 Tom Kacvinsky <tkacvins@freetype.org>
* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if
we are working with a CID keyed CFF font. Otherwise, a variable
that was never allocated memory might freed. This is a correction
to the previous patch for freeing subfonts.
2001-10-21 Tom Kacvinsky <tkacvins@freetype.org>
* src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to
avoid a memory leak.
2001-10-21 David Turner <david@freetype.org>
* src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,
src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes
(in multi-object compilation mode, mainly).
2001-10-20 Tom Kacvinsky <tkacvins@freetype.org>
* src/type1/t1load.c (parse_encoding): Add a test to make sure
that custom encodings (i.e., neither StandardEncoding nor
ExpertEncoding) are not loaded twice when the Type 1 font is
synthetic.
* src/type1/t1load.c (parse_font_name, parse_subrs): Added a test
for when loading synthetic fonts to make sure that the font name
and subrotuines are not loaded twice. This is to remove a memory
leak that occurred because the original memory blocks for these
objects were not deallocated when the objects were parsed the
second time.
2001-10-19 David Turner <david@freetype.org>
* src/smooth/ftgrays.c, src/pshinter/pshglob.h,
src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: Getting rid of
compiler warnings.
* src/pshinter/module.mk, src/pshinter/rules.mk: Adding control

files.
2001-10-18 David Turner <david@freetype.org>
* src/psnames/pstables.h, src/tools/glnames.py: Rewrote the
"glnames.py" script used to generate the "pstables.h" header file.
The old one contained a serious bug that made FreeType return
incorrect glyph names for certain glyphs.
* src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of
pixel size from character size to use rounding. This is an
experiment to see whether this gives values similar to Windows for
scaled ascent/descent/etc.
* src/base/ftcalc.c (FT_Div64by32): Changed the implementation
slightly since the original code was mis-compiled on Mac machines
using the MPW C compiler.
* src/base/ftobjs.c (FT_Realloc): When a memory block was grown
through FT_Realloc(), the new bytes were not set to 0, which created
some strange bugs in the PostScript hinter.
(destroy_face): Don't deallocate unconditionally.
* src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):
Adding support to new PostScript hinter.
* include/freetype/internal/psglobal.h,
include/freetype/internal/pshints.h,
include/freetype/config/ftmodule.h, src/pshinter/Jamfile,

src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c,
src/pshinter/pshrec.h: Adding new PostScript hinter module.
* include/freetype/internal/ftobjs.h,
include/freetype/internal/internal.h,
include/freetype/internal/psaux.h,
include/freetype/internal/t1types.h, src/psaux/psobjs.c,
src/psaux/psobjs.h, src/psaux/t1decode.h, src/psaux/t1decode.c,
src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c,
src/type1/t1objs.h: Updates to use the new PostScript hinter.
* tests/Jamfile, tests/gview.c: Adding a new glyph hinting
viewer/debugger to the source tree. Note that you will _not_ be
able to compile it since it depends on an unavailable graphics
library named "Nirvana" to render vector images.
2001-10-17 David Turner <david@freetype.org>
* Version 2.0.5 released.
=========================
* include/freetype/freetype.h, include/internal/ftobjs.h,
src/base/ftobjs.c, src/type1/t1driver.c: Adding a new function named

2001-10-08 David Turner <david@freetype.org>
Fixed a bug in `glnames.py' that prevented it from generating
correct glyph names tables. This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).
* src/tools/glnames.py (mac_standard_names): Fixed.
(t1_standard_strings): Some fixes and renamed to ...
(sid_standard_names): This.
(t1_expert_encoding): Fixed.

2001-10-07 Richard Barber <rich@solutionuk.com>
* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.
2001-10-07 David Turner <david@freetype.org>
setjmp() and longjmp() are now used for rollback (i.e. when memory
pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.
* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
too small on 16-bit systems). <limits.h> is included to properly
get the needed data type.
(TCell, TRaster): Use it.
(TRaster): New element `jump_buffer'.
(gray_compute_cbox): Use `RAS_ARG' as the only parameter and get
`outline' from it.

(gray_convert_glyph): Use it.
2001-10-07 David Turner <david@freetype.org>
Provide a public API to manage multiple size objects for a given
FT_Face in the new header file `ftsizes.h'.

FT_Activate_Size.
2001-09-20 Detlef W<>rkner <TetiSoft@apg.lahn.de>
* builds/amiga/*: Added port to Amiga with the SAS/C compiler.
2001-09-15 Detlef W<>rkner <TetiSoft@apg.lahn.de>
* src/type1/t1afm.c (T1_Done_AFM): Free `afm'.
2001-09-10 Yao Zhang <yzhang@sharemedia.com>
* src/sfnt/ttcmap.c (code_to_index2): Handle code values with
hi-byte == 0 correctly.
2001-09-10 Werner Lemberg <wl@gnu.org>
* builds/link-std.mk ($(PROJECT_LIBRARY)): Fix typo.
2001-08-30 Martin Muskens <mmuskens@aurelon.com>
* src/type1/t1load.c (parse_font_matrix): A new way to compute the
units per EM with greater accuracy (important for embedded T1 fonts
in PDF documents that were automatically generated from TrueType
ones).
* src/type1/t1load.c (is_alpha): Now supports "+" in font names;
this is used in embedded fonts.
* src/psaux/psobjs.c (PS_Table_Add): Fixed a reallocation bug that
generated a dangling pointer reference.
2001-08-30 Anthony Feik <afeick@hotmail.com>

Undefine FT_ERR_BASE before defining again.
2001-08-22 Werner Lemberg <wl@gnu.org>
* src/truetype/ttinterp.h: Fix prototype of TT_Move_Func.
2001-08-21 Werner Lemberg <wl@gnu.org>
* builds/dos/dos-def.mk (NO_OUTPUT): Don't use `&>' but `>'.
2001-08-21 David Turner <david@freetype.org>
* include/freetype/config/ftoption.h: Changed the default setting
for FT_CONFIG_OPTION_USE_MODULE_ERRORS to undefined, since it breaks
source compatibility in a few cases. Updated the comment to explain
that too.
2001-08-17 Martin Muskens <mmuskens@aurelon.com>
* src/base/ftcalc.c (FT_MulDiv): Fixed serious typo.
2001-08-12 Werner Lemberg <wl@gnu.org>

units_per_EM from the value assigned in parse_font_matrix, if
available. Default to 1000 if not available.
* src/cff/cffparse.c (cff_parse_font_matrix): Added logic to get
the units_per_EM from the FontMatrix.
(cff_parse_fixed_thousand): New function. Gets a real number from
the CFF font, but multiplies by 1000 (this is to avoid rounding
errors when placing this real number into a 16.16 fixed number).
(cff_parse_real): Added code so that the integer part is moved
into the high sixteen bits of the 16.16 fixed number.
* src/cff/cffobjs.c (CFF_Init_Face): Added logic to get the units
per EM from the CFF dictionary, if available.
* include/freetype/internal/cfftypes.h: In struct CFF_Font_Dict_,
added a units_per_em member to facilitate passing of units_per_em
from function cff_parse_font_matrix.
* src/type1/t1load.c (is_alpha): Make `-' a legal alphanumeric
character. This is so that font names with `-' are fully parsed,
etc...

src/cff/cffgload.c, src/cff/cffgload.h: Changed to use
cffgload.{c,h} instead of t2gload.{c,h}. All occurrences of t2_
(T2_) were replaced with cff_ (CFF_, respectively).
* src/cff/t2gload.h: Renamed cffgload.h.
* src/cff/t2gload.c: Renamed cffgload.c

* src/cid/cidafm.c, src/cid/cidafm.h: removed un-needed files,
we'll work on supporting CID AFM files later I guess :-)
2000-12-21 Tom Kacvinsky <tkacvins@freetype.org>
* src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph):
Changed so that fonts with a non-standard FontMatrix render
correctly. Previously, the first glyph rendered from such a
font did not have the tranformation matrix applied.

direct rendering before testing arguments.
2000-12-13 David Turner <david.turner@freetype.org>
* include/freetype/config/ft2build.h,
include/freetype/internal/internal.h: Fixed header inclusion macros

* builds/win32/detect.mk: Added support for the Intel C/C++
compiler, as well as _preliminary_ (read: doesn't work!) support for

names directly. Make them configurable. Use `##' to strip leading
and trailing spaces from arguments.

header files (an FT_FLAT_COMPILE test was missing).
* src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused
an occasional crash when the function was called (due to a dangling
pointer).
* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:
The ANSI "free()" function was called instead of "memory->free()".
* docs/docmaker.py: Added section filtering, multi-page generation
(index page generation is still missing though).
2000-12-04 David Turner <david.turner@freetype.org>
* builds/unix/install.mk, builds/unix/ft2unix.h: The file "ft2unix.h"
is now installed as <ft2build.h> for Unix systems. Note that we
still use the "freetype2/freetype" installation path for now.
* */*.[ch]: Now using <ft2build.h> as the default build and setup
configuration file in all public headers. Internal source files
still need some changes though.
* builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new
directory to hold all development options for both the Unix and
Win32 developer builds.
* builds/win32/detect.mk, builds/win32/w32-bccd.mk,
builds/win32/w32-dev.mk: Changed the developer build targets to
"devel-gcc" and "devel-bcc" in order to be able to develop with the
Borland C++ compiler.
2000-12-01 David Turner <david.turner@freetype.org>
* Version 2.0.1 released.
=========================

builds/cygwin/configure.in, builds/cygwin/configure: Setting
"version_info" to 6:1:0 for the 2.0.1 release.
* CHANGES: Added a summary of changes between 2.0.1 and 2.0.
* builds/unix/ftconfig.in, builds/cygwin/ftconfig.in: Changes
to allow compilation under Unix with the Unix-specific config
files.
2000-12-01 Werner Lemberg <wl@gnu.org>
* INSTALL: Revised.
* builds/compiler/bcc-dev.mk, builds/compiler/visualage.mk,
builds/compiler/bcc.mk, builds/win32/w32-bcc.mk,
builds/win32/w32-bccd.mk: Revised.
* include/freetype/config/ftbuild.h,
include/freetype/internal/internal.h: Revised.
* include/freetype/ftimage.h: Updated to new header inclusion scheme.
2000-11-30 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk (.PHONY): Adding `distclean'.
* builds/unix/detect.mk (.PHONY): Adding `devel', `unix', `lcc',
`setup'.
2000-11-30 David Turner <david.turner@freetype.ogr>
* INSTALL: Slightly updated the quick starter documentation to
include IDE compilation, prevent against BSD Make, and specify "make
setup" instead of a single "make" for build configuration.
* include/config/ftbuild.h, include/internal/internal.h: Added new
configuration files used to determine the location of all public,
configuration, and internal header files for FreeType 2. Modified
all headers under "include/freetype" to reflect this change. Note
that we still need to change the library source files themselves
though.
* builds/compiler/bcc.mk, builds/compiler/bcc-dev.mk,
builds/win32/w32-bcc.mk, builds/win32/w32-bccd.mk,
builds/win32/detect.mk: Added new files to support compilation with
the free Borland C++ command-line compiler. Modified the detection
rules to recognize the new "bcc32" target in "make setup bcc32".
* src/sfnt/ttcmap.c, src/sfnt/ttpost.c, src/sfnt/ttsbit.c,
src/truetype/ttobjs.c, src/truetype/ttgload.c,
src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++
didn't really like. Basically, this compiler complains when FT_UInt
is compared to FT_UShort (apparently, it promotes `UShort' to `Int'
in these cases).
2000-11-30 Tom Kacvinsky <tkacvins@freetype.org>
* t2objs.c (T2_Init_Face): Added calculation of `face->height' for
pure CFF fonts.
* t1objs.c (T1_Init_Face): Fixed computation of `face->height'.
2000-11-29 David Turner <david.turner@freetype.org>
* src/base/ftbbox.c (BBox_Conic_Check): Fixed a really stupid
bug in the formula used to compute the conic B<>zier extrema
of non-monotonous arcs.
2000-11-29 Werner Lemberg <wl@gnu.org>
* src/base/ftcalc.c (FT_SqrtFixed), src/base/ftobjs.c
(FT_Set_Renderer): Use FT_EXPORT_DEF.
* src/cache/ftcimage.c (FTC_Image_Cache_Lookup),
src/cache/ftcmanag.c (FTC_Manager_Done, FTC_Manager_Reset,
FTC_Manager_Lookup_Face, FTC_Manager_Lookup_Size,
FTC_Manager_Register_Cache), src/cache/ftcsbits.c
(FTC_SBit_Cache_Lookup): Ditto.
* src/include/freetype/cache/ftcglyph.h (FTC_GlyphNode_Init),
src/include/freetype/ftmac.h (FT_New_Face_From_FOND): Use FT_EXPORT.
2000-11-29 Werner Lemberg <wl@gnu.org>
* src/sfnt/sfdriver.c: Include ttsbit.h and ttpost.h only
conditionally.
* src/truetype/ttdriver.c (Set_Char_Sizes, Set_Pixel_Sizes): Set
`size->strike_index' only conditionally.
* src/type1/t1driver.c, src/type1/t1objs.c: Include t1afm.h only
conditionally.
* src/winfonts/winfnt.h: Move all type definitions to...
* src/include/freetype/internal/fnttypes.h: New file.
* src/winfonts/winfnt.c: Use it.
2000-11-29 ??? ??? <darin@eazel.com>
* include/freetype/internal/ftdebug.h: Replaced FT_CAT and FT_XCAT
with a direct solution (which also satifies picky compilers).
2000-11-28 YAMANO-UCHI Hidetoshi <mer@din.or.jp>
* src/truetype/ttobjs.c (TT_Init_Size): Fix #ifdef's to work with
disabled interpreter also.
* src/base/ftnames.c (FT_Get_Sfnt_Name_Count): Fix incorrect
parentheses.
2000-11-26 Tom Kacvinsky <tkacvins@freetype.org>
* src/cff/t2gload.c (T2_Parse_CharStrings): Added logic to glyph
width setting code to take into account even/odd argument counts
and glyph width operand before endchar/hmoveto/vmoveto.
2000-11-26 Werner Lemberg <wl@gnu.org>
* builds/ansi/ansi.mk: Fix inclusion order of files.
2000-11-26 Keith Packard <keithp@keithp.com>
* src/type1/t1objs.c (T1_Init_Face): Compute style flags.
2000-11-26 Werner Lemberg <wl@gnu.org>
* builds/compiler/ansi-cc.mk (CLEAN_LIBRARY): Fix rule and
conditional.
2000-11-23 Werner Lemberg <wl@gnu.org>
* src/type1/t1load.c (parse_subrs, parse_charstrings): Use decrypt
function from PSAux module.
* src/type1/t1parse.c (T1_Done_Parse): Renamed to...
(T1_Finalize_Parser): New function (to avoid name clash with a
function in the PSAux module).
(T1_Decrypt): Removed since it is duplicated in the PSAux module.
(T1_Get_Private_Dict): Added `psaux' as new parameter; use decrypt
function from PSAux module.
* src/type1/t1parse.h: Adapted.
2000-11-22 Tom Kacvinsky <tkacvins@freetype.org>
* src/cff/t2objs.c (T2_Init_Face): For pure CFF fonts, set
`root->num_faces' to `cff->num_faces' and set `units_per_EM'
to 1000.
* src/cff/t2parse.c (parse_t2_real): Fixed real number parsing
loop.
* src/cff/t2load.c (T2_Get_String): Called T2_Get_Name with a
sid that was off by one.
2000-11-16 David Turner <david@freetype.org>
* src/autohint/ahtypes.h (AH_Hinter): Added new fields to control
auto-hinting of synthetic Type 1 fonts.
* src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph):
Added auto-hinting support of synthetic Type 1 fonts.
2000-11-12 Tom Kacvinsky <tkacvins@freetype.org>
* src/sfnt/ttload.c (TT_LookUp_Table, TT_Load_Generic_Table): Change
tracing output.
* src/sfnt/sfobjs.c (SFNT_Load_Face): Set boolean variable
`has-outline' to true only if the font has a `glyf' or `CFF ' table.
2000-11-11 Werner Lemberg <wl@gnu.org>
* builds/win32/visualc/freetype.dsp: Fix raster1->raster and
type1z->type1.
2000-11-11 Tom Kacvinsky <tkacvins@freetype.org>
* builds/unix/freetype-config.in, builds/cygwin/freetype-config.in:
Added a --libtool option. When freetype-config --libtool is
invoked, the absolute path to the libtool convenience library
is returned.
2000-11-11 Werner Lemberg <wl@gnu.org>
* builds/cygwin/cygwin-def.in: Same fix as previous.
2000-11-10 Tom Kacvinsky <tkacvins@freetype.org>
* builds/unix/unix-def.in: Add
INSTALL_PROGRAM := @INSTALL_PROGRAM@
INSTALL_SCRIPT := @INSTALL_SCRIPT@
so that installation of freetype-config does not fail.
2000-11-10 Werner Lemberg <wl@gnu.org>
* builds/cygwin/freetype-config.in, builds/unix/freetype-config.in:
Move test down for empty --exec-prefix.
