defined.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)
For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'. Here, we try to
make this work for _all_ tables.
* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit. Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.
* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Pretty trace messages.
* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from
`eblc'.
* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c

* src/sfnt/sfdriver.c: Include ttmtx.h.
* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.
This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.
Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.
* modules.cfg: New file.
* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.

(distclean): Add remove_ftmodule_h.
* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables. Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed). We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.
* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.

Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.
* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed. Defined elsewhere.
* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed. Defined elsewhere.
* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.
* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.

no longer used if FreeType is built with GNU make.
* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.

[FT_STRICT_ALIASING]: Implement.
src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox',
`Ascender', and `Descender' from an AFM.
* src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.
* include/freetype/freetype.h (FT_FaceRec): Mention that fields may be
changed after file attachment.
the warp hinter isn't active (it shouldn't, still experimental)
* Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
and "otvalid" from the list of modules that are linked statically
to a given FreeType library. Functionality has been moved to the
"ftvalid" CVS module.
note also that current Make-based build system still compiles the
modules though...
* include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
which controls the definitions of the memory management functions
to avoid warnings with recent versions of GCC. this macro is
only here to be disabled, in case we detect problems with the
new scheme.
NOTE: disable macro to use the memory debugger. this will be fixed
later !!

FT_Request_Metrics): New base functions to set the font metrics. They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.
* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL. That is, drivers
should set the metrics themselves.
(FT_Match_Size): Round before matching. This was what we did and it
does cause some problems without rounding.
* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
(tt_size_select): Set the font metrics.
s/index/strike_index/.
The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected. This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.

(tt_size_request): Set the font metrics.
Call cff_size_select/tt_size_select when some strike is matched.

Set the font metrics.
s/index/strike_index/.
* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these

advertised metrics in `available_sizes' are different from those
actually used.

vertical metrics.
* src/cff/cffgload.c, src/cid/cidgload.c, src/pcf/pcfdrivr.c,
src/type1/t1gload.c, src/winfonts/winfnt.c: Fake the vertical metrics.
The fake metrics is monotone.
* src/truetype/ttgload.c (compute_glyph_metrics): Some fixes and
formattings in vertical metrics faking. There are still rooms for
improvements (and so do the CFF module).

(FT_Select_Size, FT_Request_Size): API additions to export the new
size selection interface.

face->cid_stream so that we can deallocate it safely.
Make the PS parser more tolerant w.r.t. non-standard font data. In
general, an error is only reported in case of a syntax error; a
wrong type is now simply ignored (if possible). To be independent
of the order of various MM-specific keywords, the parse_shared_dict
routine has been removed -- the PS parser is now capable to skip
this data. It no longer fails on parsing e.g.
dup /WeightVector exch def
Since the token following /WeightVector isn't `[' (starting an
array) it is simply ignored.
* include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a
new internal error value.
* src/type1/t1load.c (parse_blend_axis_types,

Set keyword_flag only in case of success.
Check error code if skipping an unrecognized token.

if blend commands haven't set up a proper MM font.
* src/psaux/psobjs.c (ps_parser_load_field_table): Remove special
code for synthetic fonts.
Return PSaux_Err_Ignore if no proper value has been found.

in first run.
(parse_charstrings): Parse /CharStrings in second run without
assigning values.
(parse_dict): Skip all /CharStrings arrays but the first. We need
this for non-standard fonts like `Optima' which have different
outlines depending on the resolution. Note that there is no
guarantee that we get fitting /Subrs and /CharStrings arrays; this
can only be done by a real PS interpreter.
(cff_get_name_index): Return if no PSNames service is available.
(cff_ps_has_glyph_names): Handle CID-keyed fonts correctly.
* src/cff/cfftypes.h (CFF_CharsetRec): New field `cids', used for

Initialize charset->cids if `invert' is set.
(cff_font_load): In call to cff_charset_load, set `invert' to true

. In all makefiles `/' is used as the path separator. The
conversion to the real path separators is done as late as
possible using $(subst ...).
. $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator
for the operating system, and the new $(COMPILER_SEP) the path
separator for the compiler tools.
. $(BUILD) has been renamed to $(BUILD_DIR). In general, all
directory variables end with `_DIR'. The variants ending in `_'
(like `BASE_' have been removed).

first version was kind of a hack; the current implementation of the
procedure to extract the required symbols is much cleaner.
Reworked creation of MMS files, avoiding a number of temporary files
which were created in the previous version.
Further work on creating descrip.mms files on the fly.
* builds/vms/descrip.mms, src/autohint/descrip.mms,
src/type1/descrip.mms: Removed.

FreeType version.
* src/base/ftobjs.c (open_face): Free `internal' not
`face->internal' in case of error to avoid possible segfault.

* 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>

Use FT_PtrDist where appropriate.
(parse_encoding): Use FT_Long for `count' and `n'.
(read_binary_data): Use FT_Long* for second parameter.
* src/type1/t1afm.c (afm_atoindex): Use FT_PtrDist.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Remove unused label.
* src/pshinter/pshalgo3.c (psh3_hint_align): Remove unused variable.
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_.
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.
src/psaux/psobjs.c, src/type1/t1load.c, src/type1/t1tokens.h:
fixing a bug in the Type 1 loader that prevented valid font bounding
boxes to be loaded from multiple master fonts.
t1_cmap_custom_char_next): Fix index computation -- indices start
with 0 and not with cmap->first.
Provide default charmaps.
* src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdriver.c
(PCF_Face_Init), src/pfr/pfrobjs.c (pfr_face_init),
src/type1/t1objs (T1_Face_Init), src/winfonts/winfnt.c

added the new configuration file "ftstdlib.h" used to define
aliases for all ISO C library functions used by the engine
(e.g. strlen, qsort, setjmp, etc...)
this eases the porting of FreeType 2 to exotic environments like
XFree86 modules/extensions..

MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
MEM_Move => FT_MEM_MOVE
ALLOC => FT_ALLOC
FREE => FT_FREE

FT_NEW was introduced to allocate a new object from a _typed_

note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer

these contain some fields that may change between releases
of FreeType, without affecting the size of FT_FaceRec,
FT_SizeRec, FT_GlyphSlotRec, etc.., which means that
drivers wouldn't need to be recompiled if we only add new
fields to an internal structure..
I plan to hack a few things related to the auto-hinter and
I need this move to ensure that we will not break binary
compatibility between 2.0 and 2.1 :-)
- David
Fixed some data types/added header files to remove compiler warnings.
Added trivial input data check to FT_Outline_Get_BBox().
Fixed type1z -> type1 file inclusions.
"type1z" -> "type1"
"raster1" -> "raster"
note that I didn't rename all files. We'll have to endure
the "z1..." crazyness unless we perform a _big_ sed on
the sources :-)
More C++ fixes: Introducing LOCAL_FUNC_X for local functions used in
function pointers (there are no local anonymous functions in C++) and
FT_CPLUSPLUS (instead of FT_EXPORT_VAR) to define linkage of structures
which contain function pointers.
Instead, define BASE_DEF() and BASE_FUNC() similarly to FT_EXPORT_DEF() and
FT_EXPORT_FUNC(), respectively, allowing the programmer to define proper
types and/or export lists for multiple DLLs if necessary (e.g. ftbase.dll --
standalone, fttype1.dll -- needs ftbase.dll, etc.).
The library is finally compiling and linking natively with a C++ compiler!
- disabled the TrueType interpreter by default
- disabled the "type1" driver, "type1z" is now used
by default (the internal driver name is "type1" now !!)
Formatting.
Replacing many enums with #defines since we do arithmetics (especially
ORing which would produce undefined enum values). The ideal thing instead
of #defines is `const int' as provided in C++...
Adding header files to rules.mk
to access individual glyph names. Changed some
drivers to support it through a new interface named
"glyph_name".
- introduced FT_Get_Sfnt_Name (see ftnames.h)
to access the SFNT name table in a TrueType/OpenType
file..
Moving some internal structures and constants from freetype.h to ftobjs.h.
Finally removing FT_LOAD_ANTI_ALIAS.
Cleaning up all error codes. Only the used ones have survived :-)
Removed unused FT_MAX_GLYPH_FORMATS constant.
T2 error codes are now in the range 0x500-0x5FF (instead of `TrueDoc').
Some minor improvements of error return values.
Finally fixing error code values in ftraster and ftgrays to be compliant
with all other FT error codes.
C++ programs easier:
Renamed FT_WordXX to FT_UIntXX.
Changed a lot of void* to FT_Byte* if related to i/o streams -- FreeType
always accesses streams byte-wise, so this makes sense IMHO.
Added a lot of #ifdef __cplusplus to header files (and removed a few).
Other minor syntax fixes (mostly casts).
Replaced the variable `private' with `private_dict' -- `private' is
reserved in C++.
- using FT_UNUSED instead of UNUSED
- using FT_LONG64 and FT_INT64 instead of LONG64 & INT64
- using FT_SIZEOF_INT & FT_SIZEOF_LONG instead of...
- removed the #ifdefs that used SIZEOF_INT, instead we now
use FT_Int32 and FT_UInt32 when needed to support
32-bits quantity correctly on 64-bits systems..
It is now really the "glyph factory" that Stefan was probably
dreaming about..
fixed some recent formatting errors from Werner ;-)
cleaned up the demonstration programs from most of the
rust that they had, though I'm sure someone is going to
re-format them really soon !!
"ftstring" now uses the new ftglyph.h API, and is now
faster and smaller.. yep..
the lenIV field is set to -1 to indicate unencoded charstrings
fixed some source code to prevent a compiler bug on IRIX
fixed the module version's in the "type1z" driver
A lot of internal modifications have been performed lately on the
source in order to provide the following enhancements:
- more generic module support:
The FT_Module type is now defined to represent a handle to a given
module. The file <freetype/ftmodule.h> contains the FT_Module_Class
definition, as well as the module-loading public API
The FT_Driver type is still defined, and still represents a pointer
to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
FT_Get_Driver by FT_Get_Module, etc..
- support for generic glyph image types:
The FT_Renderer type is a pointer to a module used to perform various
operations on glyph image.
Each renderer is capable of handling images in a single format
(e.g. ft_glyph_format_outline). Its functions are used to:
- transform an glyph image
- render a glyph image into a bitmap
- return the control box (dimensions) of a given glyph image
The scan converters "ftraster.c" and "ftgrays.c" have been moved
to the new directory "src/renderer", and are used to provide two
default renderer modules.
One corresponds to the "standard" scan-converter, the other to the
"smooth" one.
The current renderer can be set through the new function
FT_Set_Renderer.
The old raster-related function FT_Set_Raster, FT_Get_Raster and
FT_Set_Raster_Mode have now disappeared, in favor of the new:
FT_Get_Renderer
FT_Set_Renderer
see the file <freetype/ftrender.h> for more details..
These changes were necessary to properly support different scalable
formats in the future, like bi-color glyphs, etc..
- glyph loader object:
A new internal object, called a 'glyph loader' has been introduced
in the base layer. It is used by all scalable format font drivers
to load glyphs and composites.
This object has been created to reduce the code size of each driver,
as each one of them basically re-implemented its functionality.
See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
more information..
- FT_GlyphSlot had new fields:
In order to support extended features (see below), the FT_GlyphSlot
structure has a few new fields:
linearHoriAdvance: this field gives the linearly scaled (i.e.
scaled but unhinted) advance width for the glyph,
expressed as a 16.16 fixed pixel value. This
is useful to perform WYSIWYG text.
linearVertAdvance: this field gives the linearly scaled advance
height for the glyph (relevant in vertical glyph
layouts only). This is useful to perform
WYSIWYG text.
Note that the two above field replace the removed "metrics2" field
in the glyph slot.
advance: this field is a vector that gives the transformed
advance for the glyph. By default, it corresponds
to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
was specified when calling FT_Load_Glyph or FT_Load_Char
bitmap_left: this field gives the distance in integer pixels from
the current pen position to the left-most pixel of
a glyph image WHEN IT IS A BITMAP. It is only valid
when the "format" field is set to
"ft_glyph_format_bitmap", for example, after calling
the new function FT_Render_Glyph.
bitmap_top: this field gives the distance in integer pixels from
the current pen position (located on the baseline) to
the top-most pixel of the glyph image WHEN IT IS A
BITMAP. Positive values correspond to upwards Y.
loader: this is a new private field for the glyph slot. Client
applications should not touch it..
- support for transforms and direct rendering in FT_Load_Glyph:
Most of the functionality found in <freetype/ftglyph.h> has been
moved to the core library. Hence, the following:
- a transform can be specified for a face through FT_Set_Transform.
this transform is applied by FT_Load_Glyph to scalable glyph images
(i.e. NOT TO BITMAPS) before the function returns, unless the
bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..
- once a glyph image has been loaded, it can be directly converted to
a bitmap by using the new FT_Render_Glyph function. Note that this
function takes the glyph image from the glyph slot, and converts
it to a bitmap whose properties are returned in "face.glyph.bitmap",
"face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
native image might be lost after the conversion.
- when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
and FT_Load_Char functions will call FT_Render_Glyph automatically
when needed.
rid of most of the basic types redefinitions (i.e. FT_Int instead
of "FT_Int", etc..)
The format-specific prefixs like "TT_", "T1_", "T2_" & 'CID_"
are now only used in relevant structures..
fixed Werner's fix to t2gload.c :-)
other small bug fixes
compiler warnings with GCC + "-ansi -pedantic -Wall -W"
and LCC.
Also fixed the compilation of "type1z" with Win32-LCC
(its pre-processor is broken !!)
Updated the BUILD document too
EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to
let them take an argument..
This is needed to compile the library as a DLL on some platforms
that have different compiler conventions..
Generates a Unicode charmap on the fly
through the "psnames" module..
Now, we only need to support afm/pfm
files (and maybe multiple masters) to call
this driver finished !!
use "$(FT_COMPILE)" instead of "$(FT_CC)" in order to
compile the library.
$(FT_COMPILE) uses the $(ANSI_FLAGS) variable used to
define ANSI-compliance flags for the current compiler. It is used
to compile the library exclusively (some demo programs will _not_
compile properly with these flags set).
reflect the new modules/drivers list management performed through the
file `freetype2/config/modules.mk'
Changed the driver header files to reflect the new modules/drivers
list management. We get rid, at last, of the infamous pre-processor
tricks used to build the list at compile time.
`src/base/ftinit.c' is also modified to reflect the changes..
