After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only. For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction. Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).
* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
`advance_v' field to hold the vertical component of the advance
value.

quickly load the glyph header only.
Update all callers.
(tt_loader_init): Add parameter to quickly load the `glyf' table
only.
Update all callers.
(TT_Load_Glyph): Compute linear advance values for embedded bitmap
glyphs too.
The calculation of `vertBearingX' is not defined in the OTF font
spec so FreeType does a `best effort' attempt. However, this value
is defined in the PDF and PostScript specs, and that algorithm is
better than the one FreeType currently uses:
FreeType: Use the middle of the bounding box as the X coordinate
of the vertical origin.
Adobe PDF spec: Use the middle of the horizontal advance vector as
the X coordinate of the vertical origin.
FreeType's algorithm goes wrong if you have a really small glyph
(like the full-width, circle-like dot at the end of the sentence, as
used in CJK scripts) with large bearings. With the FreeType
algorithm this dot gets centered on the baseline; with the PDF
algorithm it gets the correct location (in the top right). Note
that this is a serious issue, it's like printing the dot at the end
of a Roman sentence at the center of the textline instead of on the
baseline like it should. So i believe the PDF spec's algorithm
should be used in FreeType as well.
The `vertBearingY' value for such small glyphs is also very strange
if no `vmtx' information is present, since the height of the bbox is
not representable for the height of the glyph visually (the
whitespace up to the baseline is part of the glyph). The fix also
includes some code for a better estimate of `vertBearingY'.
* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
is now calculated as described by the Adobe PDF Spec. Estimate for
`vertBearingY' now works better for small glyphs completely above or
below the baseline into account.
* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
calculated as described by the Adobe PDF Spec. Vertical metrics
information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
was not defined.
* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
now calculated as described by the Adobe PDF Spec.
* src/truetype/ttobjs.c (tt_size_init_bytecode): Don't reset x_ppem
and y_ppem. Otherwise the `*_CVT_Stretched' functions in ttinterp.c
get never called.
An anonymous guy suggested this change on Savannah, and it seems to
be the right solution.
Normally, the SCANMODE instruction (if present) to set the drop-out
mode in a TrueType font is located in the `prep' table only and thus
valid for all glyphs. However, there are fonts like `pala.ttf'
which additionally contain this instruction in the hinting code of
some glyphs (but not all). As a result it can happen that a
composite glyph needs multiple drop-out modes for its subglyphs
since the rendering state gets reset for each subglyph.
FreeType collects the hinted outlines from all subglyphs, then it
sends the data to the rasterizer. It also sends the drop-out mode
-- after hinting has been applied -- and here is the error: It sends
the drop-out mode of the last subglyph only; drop-out modes of all
other subglyphs are lost.
This patch fixes the problem; it adds a second, alternative
mechanism to pass the drop-out mode: For each contour, the
rasterizer now checks the first `tags' array element. If bit 2 is
set, bits 5-7 contain the contour's drop-out mode, overriding the
global drop-out mode.
* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
`tags[0]'.
* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
Use bits 3-5 instead of 0-2.

necessary.
(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out

the following structs:
tt_service_gx_multi_masters, tt_service_truetype_glyf, tt_driver_class

instead of being allocated in the global scope.
And macros will be used from ttpic.h in order to access them
from the pic_container.
* src/truetype/ttobjs.c change trick_names array to be
PIC-compatible by being a two dimentional array rather than array
of pointers.
New Files:
* src/truetype/ttpic.h declare struct to hold PIC globals for truetype
driver and macros to access them.
* src/truetype/ttpic.c implement functions to allocate, destroy and
initialize PIC globals for truetype driver.
* src/truetype/truetype.c add new file to build: ttpic.c.
* src/truetype/jamfile add new files to FT2_MULTI build: ttpic.c.
extern const FT_Module_Class
(or similar for C++). However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.
To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:
All declarations that refer to the same object or function shall
have compatible type; otherwise, the behavior is undefined.
(And they are not compatible types.)
Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does. (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)

drastically reduce the heap usage of FreeType, especially in the case
of memory-mapped files. The idea is to avoid loading and decoding tables
in the heap, and instead access the raw data whenever possible (i.e.
when it doesn't compromise performance).
This had several impacts: first, opening vera.ttf uses a ridiculous amount
of memory (when the FT_Library footprint is accounted for), until you start
loading glyphs. Even then, you'll save at least 20 Kb compared to the non
optimized case. performance of various operations, including open/close
has also been dramatically improved.
More optimisations to come. The auto-hinter eats memory like crazy? This
must be stopped...
src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c:

optimizations used to reduce the heap footprint of memory-mapped TrueType
files.
* src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location,

(Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid,
Round_Up_To_Grid, Round_To_Double_Grid, Round_Super,
Round_Super_45): Fix rounding of value zero.
(DO_DIV): Don't use TT_MULDIV.
(Ins_SHC): This instruction actually touches the points.
(Ins_MSIRP): Fix undocumented behaviour.
* src/truetype/ttinterp.h (TT_ExecContextRec): Updated.
* docs/VERSION.DLL: Updated.
* src/base/ftobjs.c (FT_Set_Char_Size): Make metrics->x_scale and
metrics->y_scale really precise.
(FT_Load_Glyph): Update computation of linearHoriAdvance and
linearVertAdvance.
* src/true/type/ttinterp.c (Update_Max): Use FT_REALLOC.
include/freetype/internal/psnames.h (removed),
include/freetype/internal/internal.h (FT_SERVICE_POSTSCRIPT_NAMES):
added new service to handle glyph name dictionaries, replacing
the old internal header named "psnames.h" by "services/svpsname.h"
note that this is different from "services/svpostnm.h" which only
handles the retrieval of Postscript font name for a given face.
(should we merge these two services into a single header ??)
* include/freetype/internal/ftserv.h: adding
FT_FACE_FIND_GLOBAL_SERVICE (used to lookup a service globally,
instead of only within the current module)
* include/freetype/internal/ftobjs.h, src/base/ftobjs.c: adding
the new base function ft_module_get_service
include/freetype/internal/service/svpfr.h,
include/freetype/internal/pfr.h,
src/base/ftpfr.c:
migrating the functions of "ftpfr.h" to the new

heavy internal modifications to introduce the concept of
"module services". This is the first step towards a massive
simplification of the engine's internals, in order to
get rid of various numbers of hacks.
Note that this changes will break source & binary compatibility
for authors of external font drivers.
Maybe 2.1.6 will be called 2.2.0 after all :-)
include/freetype/internal/ftobjs.h, include/freetype/internal/tttypes.h,
src/truetype/ttinterp.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h:
changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to
the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING
removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead,
the same effect can be used by setting a debug-hook with
FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.
* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.
Synchronize computation of height and width for bitmap strikes. The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes. The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
argument to function.

. 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).
The following ChangeLog entries only describe changes which are
not related to the redesign.

[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Call
FT_GlyphLoader_CheckPoints before adding phantom points. This fixes
a segfault bug with fonts (e.g. htst3.ttf) which have nested
subglyphs more than one level deep. Reported by Anthony Fok.
* include/freetype/config/ftoption.h: Define
TT_CONFIG_OPTION_BYTECODE_INTERPRETER,
TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING, and
TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING to make it the new
default.
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/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c,
ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory
conditions.
* src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a
small memory leak
* src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that
only happened when trying to resize an array would end in an OOM.
* src/smooth/ftgrays.c: removed compiler warnings / volatile bug
* src/truetype/ttobjs.c: removed segmentation fault that happened in
tight memory environments.
when available in Asian fonts
* src/sfnt/ttload.c, src/base/ftobjs.c: changed "asian" to "Asian" in
comments
* 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.
* include/freetype/config/ftoption.h, src/autohint/ahglobal.h,
src/autohint/ahglobal.c, src/autohint/ahglyph.c,
src/autohint/ahtypes.h:
included David Chester's patches to the auto-hinter in order to
slightly improve the output. Note that everything is controlled
through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the
end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX
macros to control individual "features".
Note that all improvements are enabled by default, but can be
tweaked for optimization and testing purpose. The configuration
macros will most likely disappear in the short future.
2003-01-11 David Turner <david@freetype.org>
* include/freetype/internal/fnttypes.h: fixed a structure field
definition to avoid memory overwrites
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.
2002-11-05 Juliusz <jch@pps.jussieu.fr>
* src/psaux/psobjs.c (ps_table_add): modified increment loop in
order to implement exponential behaviour
debug mode of template instantiation
* src/cff/cffparse.c: fixed the CFF table loader. It didn't accept
empty arrays, and this prevented the loading of certain fonts.
* src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to
prevent seg fault when hints are provided in an empty glyph !!
* include/freetype/ftimage.h: removed incorrect "zft_" definitions
and updated constants documentation comments
* include/freetype/freetype.h (FT_FaceRec): updating documentation
comment. The "descender" value is always *negative*, not positive !
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_.

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.

been never used.
bug that prevented FreeType 2.x and FreeType 1.x to produce
bit-by-bit identical monochrome glyph bitmaps with native TrueType

FT_LOCAL_DEF.
* src/truetype/ttinterp.c: s/FT_Assert/FT_ASSERT/.
* builds/unix/configure.ac: Temporarily deactivate creation of
../../Jamfile.
* builds/unix/configure: Updated.
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..

unpleasant overwrites in the case of invalid glyph data (found in
the output of buggy font converters)
the computation of auto-hinted stem widths has been modified to
avoid certain color fringes in LCD-decimation rendering (a.k.a.
"ClearType")
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: added the
FT_Outline_Check API to check the consistency of outline data
* src/base/ftobjs.c (FT_Load_Glyph): added a call to the new
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.. !!
(FT_Load_Glyph): "fixed" the bug that prevented embedded bitmaps from
begin 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
some of the exported functions should only be used by applications
that need to implement custom cache types
* src/truetype/ttgload.c: fixed a nasty bug that prevent composites
from loading correctly. Believe it or not, this was due to an invalid
macro definition !!

macros.
(FT_NOERRORDEF): Removed.
* include/*/*err*.h: Use FT_ERRORDEF_ and FT_NOERRORDEF_.
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

Fixed a bug that returned an invalid linear width for composite
TrueType glyphs.

macro.
* include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro.

some already existing (internal) error codes local to a module have
been renamed to give them the same name as in the base module.
All make files have been updated to include the local error files.

This is already used in the link_*.mk files.
* src/*/Jamfile: Slight changes to make files more cryptic.
* include/freetype/config/ftheader.h: removed obsolete macros like
FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that
were previously defined in <freetype/ftcache.h>. Added comments to be
included in a new API Reference section.
* src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component
needs to added its own directory to the include path at compile time.
Modified all "rules.mk" and "descrip.mms" accordingly..
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.
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,
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..
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.
* 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.
`__' (those which haven't converted yet). Fixed minor conversion
issues.
* src/winfonts/winfnt.c: Updated to new header inclusion scheme.
* */*.[ch]: Changed source files to adhere to the new
* src/cff/cff.c, src/cff/rules.mk: Updated.
* */*.[ch]: Now using <ft2build.h> as the default build and setup
in the "builds" directory
- modified a few files because BCC32 didn't like certain comparisons
(UInt compared with a UShort, apparently the UShort is promoted to
an Int)
- updated the INSTALL file to include IDE compilation, prevent against
BSD Make, and clarify the use of "make setup" (instead of "make")
for build configuration
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.
* include/freetype/internal/ftdebug.h: Replaced FT_CAT and FT_XCAT
with a direct solution (which also satifies picky compilers).
I've made a few modifications:
- there is no new field named "driver" in "FT_SizeRec"
- the new fields in "TT_SizeRec" are:
strike_index :: value 0xFFFF means "no sbit strike selected"
strike_metrics :: the FT_Size_Metrics structure corresponding to
the currently selected strike
- the code in "ttload.c" has been somewhat cleaned up too
thanks a lot, Y-U !!

objects:
FT_Face_Internal, FT_Size_Internal, FT_Slot_Internal
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 :-)

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!
you should #define FT_STRUCTURE to the structure which will be filled.
Replaced FT_FIELD_REF with FT_FIELD_SIZE, FT_FIELD_SIZE_DELTA, and
FT_FIELD_OFFSET to make the code more readable; additionally, it should be
more portable because we no longer cast a pointer to an FT_UShort (which
e.g. fails with Sun's C++ compiler) but computes the difference between two
pointers which is guaranteed to work.
Fixing warnings (and C++ errors) while using Sun's latest cc and CC
incarnations. Most of them are related to variable shadowing.
Now unix.in uses absolute paths also to overcome problems with libtool.
To do that in a consistent way I had to modify the rules how to handle
$OBJ_DIR (and consequently $LIB_DIR): You should set $OBJ_DIR explicitly
on the command line (or environment).
- disabled the TrueType interpreter by default
- disabled the "type1" driver, "type1z" is now used
by default (the internal driver name is "type1" now !!)
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..
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
Tons of unnecessary stuff have been removed; only the essential rules
have been retained.
The source files now depend on all header files in include/freetype,
include/freetype/config, and include/freetype/internal. This is not
optimal, I know, and I'll try to improve this, but it is better than
before (namely no dependencies on `internal').
FTDEBUG_SRC has been added (similar to FTSYS_SRC) -- I don't know
exactly whether this is really useful, but it doesn't harm.
There is now more documentation in the makefiles itself.
io-frames.html: Use of <th>, <code>, and <var> for better tagging.
Reactivating of FT_DEBUG_LEVEL_xxx macros.
Added a lot of #include directives to make `multi' builds possible -- note
that currently the modules cid, t1, and t1z have clashing structures and
functions which means that you can only use one of these three modules for a
multi build.
Added some missing function declarations to (local) header files.
Renamed some T1_Open_Face() to CID_Open_Face() in the cid module -- a lot
of other functions should be renamed also...
Replaced many FT_xxx stuff with T1_xxx in t1z driver -- this isn't finished
yet...
Fixed FT_Free() to allow a NULL pointer without an assertion (this has
always been a valid assumption in FreeType, at least in FT 1.x).
A lot of other, minor fixes (mostly documentation).
Added a lot of \n to tracing messages.
Fixed a serious bug in loading SBit offsets (missing parentheses around a
xxx ? yyy : zzz construct).
Replaced most GET_xxx() functions with calls to READ_Frame() in ttsbit.c
limit on the number of subglyphs in a TrueType font..
changed the default number of gray levels used by the
smooth renderer to 256 (instead of 128). Of course, the
human eye can't tell a difference ;-)
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..
fixed:
. Removing unused variables.
. detect.mk files now must provide $(CONFIG_FILE) and not $(CONFIG_RULE).
. ansi.mk will now be really used as a fallback if the detect mechanism
fails.
. ANSIFLAGS will now be really used (fixing a typo).
. `make clean' now works (again two typos).
. Detection of gcc on Unix has been fixed (using the `-v' option instead of
`--version').
. `make devel' now works (on Unix).
. Fixing *again* a bug in demos/graph/x11/rules.mk to allow multiple use
of `-L' compiler options.
. $(BASE_H) now contains a few more header files.
As usual, a lot of formatting (not finished yet).
