default..
- created "builds/devel" to hold developer builds options
for both Win32 and Unix
- fixed a bug in the winfonts driver, where the glyph image format
wasn't set correctly..
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 :-)
- 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.
Adding a new error, FT_Err_Invalid_Pixel_Size (used in winfnt.c)
Fixing FT_Read_Fields() which failed for ft_frame_{bytes,skip}. This bug
disabled the Winfont driver.
Minor formatting issues.
16.16 square root of a 16.16 number (this could come handy
in a later version of the auto-hinter)
- small fixes to the smooth renderer. It used to use way too
much line segments when drawing beziers !!
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.
- removed a stupid memory leak
- fixed the weird metrics hinting (the horizontal edges were used,
instead of the vertical one, to compute the metrics adjustments,
silly, silly, silly).
there is still some bugs that I'm looking at though, but we're
very near the release..
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..
Adding trivial argument checking to some functions.
Added dynamic driver interface to cidriver.
Minor `version' fixes for macfont and psnames modules.
Removed unnecessary files
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
trace level.
Since FT2 is still beta, I've activated the FT_DEBUG_xxx macros by default.
To make reasonable output, I've changed some TRACEx macros to other levels.
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..
- there is now a "convenience" API to manage glyphs in
"include/ftglyph.h". See the demo program "ftstring" for
an example..
- the raster interface has been changed in order to allow
direct composition through user-provided callbacks. This
has been tested but isn't demonstrated for now in "demos"
- the FT_LOAD_NO_RECURSE flag is supported, as this is
required by some new code in the auto-hinting engine
- some bug fixed in FT_MulFix which made FT_xxx_Transform
return incorrect results..
- ft_done_stream: remove the FREE(pathname) call, which wasn't
kosher
- FT_Open_Face: after calling open_face, don't assume driver is
the same as face->driver, use face->driver instead
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.
. $(BASE_H) now contains a few more header files.
As usual, a lot of formatting (not finished yet).
- modified the interface of the "sfnt" module. There is now a function
called "load_format_tag", and another called "load_directory".
The first one is in charge of returning the 4-byte tag located at
the beginning of a given font file. It understand TrueType collections
and parses them automatically
The second loads the table directory that is located just after
the format tag.
This is useful, because the "SFNT" storage scheme can be used by
several distinct formats, each with its own format tag.
The TrueType driver now checks the format tag in "src/truetype/ttobjs.c"
- made some changes to "src/shared/t1types.h" to clearly separate the
Type 1 font content from the rest of the T1_Face structure. This
will be useful when adding the CFF/Type2 driver that will be able
to reuse the "T1_Font" structure within a "TT_Font" one (which
really describes a SFNT-based font file).
Some changes in "src/type1" were thus performed to reflect this.
Note that the current type1 driver will be discontinued in a
distant future. More on this later..
use "$(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).
(they didn't updated the stream position in the case of
disk-based streams. This went un-noticed under Linux
which uses memory-mapped files by default)
introduced to use a constant precision and dynamic bezier decomposition
thresholding, leading some performance improvements.
Note that by now, the "high_precision" field of a FT_Outline
is ignored by the raster..
support for multiple X11R6 entries in $(PATH) added.
ftxbbox.c, ftcalc.c, ftdebug.c, ftdriver.h:
doc fixes.
ftdebug.c:
formatting.
ftdebug.h:
making makros `;'-safe (i.e., they can now be used within if-else clauses
without side effects resp. don't produce a single `;').
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..
large glyph images are generated (e.g. ` fttimer -g' runs 20% faster).
For small pixel sizes (i.e. typically less than 64 pixels), rendering
speed is unaffected.
