* include/freetype/freetype.h (FT_ENC_TAG): New macro.
(FT_Encoding_): Use it.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Define it
conditionally.
2001-06-14 David Turner <david@freetype.org>
Modified the TrueType interpreter to let it use the new
trigonometric functions provided in "fttrigon.h". This gets rid of
some old 64-bit computation routines, as well as many warnings when
compiling the library with the "long long" 64-bit integer type.
* include/freetype/config/ftoption.h: Undefine
FT_CONFIG_OPTION_OLD_CALCS.
* include/freetype/internal/ftcalc.h: Rearrange use of
FT_CONFIG_OPTION_OLD_CALCS.
* src/base/ftcalc.c: Add declaration of FT_Int64 if
FT_CONFIG_OPTION_OLD_CALCS isn't defined.
* src/truetype/ttinterp.c: Use FT_TRIGONOMETRY_H.
(Norm): Add a special version if FT_CONFIG_OPTION_OLD_CALCS isn't
defined.
(Current_Ratio, Normalize): Simplify code.

compiler warnings.
2001-06-08 Werner Lemberg <wl@gnu.org>
* builds/unix/configure.in: Renamed to ...
* builds/unix/configure.ac: This to make sure that autoconf 2.50 is
needed.
Run `autoupdate' on it.
Increase `version_info' to 7:0:1.
* builds/unix/configure: Regenerated.
2001-06-08 David Turner <david@freetype.org>
* src/autohint/ahhint.c (ah_hinter_load_glyph): Fixed a bug that
corrupted transformed glyphs that were auto-hinted (the transform
was applied twice).
Fixed a bug that returned an invalid linear width for composite
TrueType glyphs.
* include/internal/tttypes.h (TT_Loader_): Two new elements `linear'
and `linear_def'.
* src/truetype/ttgload.c (load_truetype_glyph,
compute_glyph_metrics): Use it.
* include/fttypes.h (FT_ERROR_BASE): New macro.
* src/base/ftobjs.c (FT_Open_Face, FT_Render_Glyph_Internal): Use it
to make source code work with the new error scheme implemented by
Werner.
* src/base/ftoutln.c (FT_Outline_Render): Ditto.
2001-06-07 Werner Lemberg <wl@gnu.org>
Updating to libtool 1.4.0 and autoconf 2.50.
* builds/unix/ltconfig: Removed.
* builds/unix/ltmain.sh, builds/unix/configure.in,
builds/unix/aclocal.m4: Updated.
* builds/unix/configure: Regenerated.
2001-06-06 Werner Lemberg <wl@gnu.org>
Complete redesign of error codes. Please check ftmoderr.h for more
details.
* include/freetype/internal/cfferrs.h,
include/freetype/internal/tterrors.h,
include/freetype/internal/t1errors.h: Removed. Replaced with files
local to the module. All extra error codes have been moved to
`fterrors.h'.
* src/sfnt/ttpost.h: Move error codes to `fterrors.h'.
* src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h,
src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h,
src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h,
src/smooth/ftsmerrs.h, src/truetype/tterrors.h,
src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the
error names for the module it belongs to.
* include/freetype/ftmoderr.h: New file, defining the module error
offsets. Its structure is similar to `fterrors.h'.

macro.
* include/freetype/config/ftoption.h

* src/raster/ftraster.c: Use macros for header file names.
* src/include/freetype/tttables.h (TT_HoriHeader_, TT_VertHeader_):
Fix length of `Reserved' array. Note that this isn't the real fix
since recent OpenType specs have introduced a `CaretOffset' field
instead of the first reserved byte.
2001-05-29 Werner Lemberg <wl@gnu.org>
* INSTALL: Minor fixes.
* Version 2.0.3 released.
=========================
2001-05-29 David Turner <david@freetype.org>

rendering, while sometimes introducing their own artefacts. This is
probably the last big change to the autohinter before the
introduction of a complete replacement.
* src/autohint/ahglobal.c (sort_values): Fix loop.
* src/autohint/ahglyph.c: Removed some obsolete code.
(ah_outline_compute_edges): Modify code to set the ah_edge_round

problems with Make on Windows 2000, as well as problems when "make
distclean" is invoked on a non-Unix platform when there is no
"config.mk" in the current directory.
* builds/freetype.mk: Fixed a problem with object deletions under
Dos/Windows/OS/2 systems.
Added new directory to hold tools and test programs.

* src/tools/docmaker.py: Improved the script to add the current date
at the footer of each web page (useful to distinguish between
versions).
* Jamfile: Fixed incorrect HDRMACRO argument.
* TODO: Removed the cubic arc bbox computation note, since it has been
fixed recently.
* src/base/ftbbox.c (test_cubic_zero): Renamed to...
(test_cubic_extrema): This function. Use `UL' for unsigned long
constants.

computation.
2001-05-08 David Turner <david@freetype.org>
* docs/docmaker.py: Updated the DocMaker script in order to add
command line options (--output,--prefix,--title), fix the erroneous
line numbers reported during errors and warnings, and other
formatting issues.
* src/base/ftcalc.c (FT_MulDiv, FT_MulFix, FT_DivFix): Various tiny
fixes related to rounding in 64-bits routines and
pseudo-"optimizations".
2001-04-27 David Turner <david@freetype.org>
* src/base/ftbbox.c (BBox_Cubic_Check): Fixed the coefficient
normalization algorithm (invalid final bit position, and invalid
shift computation).

2001-04-26 David Turner <david@freetype.org>
* src/base/ftcalc.c (FT_SqrtFixed): Corrected/optimized the 32-bit
fixed-point square root computation. It is now used even with
64-bits integers, as it is _much_ faster than calling FT_Sqrt64 :-)
* src/base/ftbbox.c: Removed invalid "#include FT_BEZIER_H" line.
2001-04-25 David Turner <david@freetype.org>
* src/base/ftbbox.c (BBox_Cubic_Check): Rewrote function to use

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...
2001-02-02 Werner Lemberg <wl@gnu.org>
* src/psaux/psobjs.c (shift_elements): Remove if clause (which is
obsolete now).
(reallocate_t1_table, PS_Table_Done): Replace REALLOC() with ALLOC()
+ MEM_Copy() to avoid a memory bug.
2001-02-01 David Turner <david.turner@freetype.org>

* src/cff/t1load.c (parse_font_matrix): Added heuristic to get
units_per_EM from the font matrix.
(parse_dict): Deleted test to see whether the FontInfo keyword has
been seen. Deletion of this test allows fonts without FontInfo
dictionaries to be parsed by the Type 1 driver.
(T1_Open_Face): Deleted empty subroutines array test to make sure
fonts with no subroutines still are parsed.
2001-01-17 Francesco Zappa Nardelli <francesco.zappa.nardelli@ens.fr>
* src/pcfread.c (pcf_get_properties, pcf_get_metrics,

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

(CFF_Load_Charset, CFF_Load_Encoding): Remove unnecessary variable
definition.
2000-12-30 Tom Kacvinsky <tjk@ams.org>
* include/freetype/internal/t2types.h,
include/freetype/internal/cfftypes.h: Changed the structures for
CFF_Encoding and CFF_Encoding for the new implementations of the
charset and encoding parsers in the CFF driver.

CFF driver is finished with them. Added tables
cff_isoadobe_charset
cff_expert_charset
cff_expertsubset_charset

* src/cff/t2gload.c (T2_Load_Glyph): Added code so that the font
transform is applied.
* src/cff/cffparse.c (cff_parse_font_matrix): Added code so that
the font matrix numbers are scaled by 1/(matrix->yy). Also, the
offset vector now contains integer values instead of 16.16 fixed
numbers.
2000-12-22 Tom Kacvinsky <tjk@ams.org>
* src/autohint/ahhint.c (ah_hinter_load_glyph):
Removed unnecessary comments and commented-out code.
2000-12-21 David Turner <david.turner@freetype.org>
* 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 <tjk@ams.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.
2000-12-17 Werner Lemberg <wl@gnu.org>
* *.mk: Added lots of `.PHONY' targets.
2000-12-17 Karsten Fleischer <kfleisc1@ford.com>
* *.mk: Implemented `platform' target to disable auto-detection.
2000-12-14 Werner Lemberg <wl@gnu.org>

* INSTALL: Updated installation instructions on Win32, listing the
new "make setup list" target used to list supported
compilers/targets.
* src/raster/ftraster.c (ft_black_render): Test for unsupported
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
to use direct definitions. This is the only way to do these things
in a portable way :-( The rest of the code should follow shortly
though everything compiles now.
* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.
* builds/win32/detect.mk: Added support for the Intel C/C++
compiler, as well as _preliminary_ (read: doesn't work!) support for
Watcom. Also added a new setup target. Type "make setup list" for
a list of supported command-line compilers on Win32.
* src/base/ftdebug.c: Added dummy symbol to avoid empty file if
conditionals are off.
2000-12-13 Werner Lemberg <wl@gnu.org>

ftconfig.h file.
2000-12-12 Werner Lemberg <wl@gnu.org>
* include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):
Removed. ANSI C doesn't (explicitly) allow macro expansion in
arguments using `##'.
(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
names directly. Make them configurable. Use `##' to strip leading
and trailing spaces from arguments.
* builds/unix/ft2unix.h: Adapted.
* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,
ft_close_stream): Use FT_CALLBACK_DEF.
* builds/unix/ftsystem.c: Use new header scheme.
(FT_Done_Memory): Use free() from FT_Memory structure.
* src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes.
2000-12-11 Werner Lemberg <wl@gnu.org>
* include/freetype/config/ft2build.h (FT2_CONFIG_ROOT,
FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE,
FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.

2000-12-05 David Turner <david.turner@freetype.org>
* src/psaux/psauxmod.c: Fixed a broken inclusion of component
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.

* 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/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 <tjk@ams.org>
* t2objs.c (T2_Init_Face): Added calculation of `face->height' for

(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.

(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 <tjk@ams.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.
