LATEST CHANGES BETWEEN 2.0.2 and 2.0.1
|
||||
|
||||
- changed the library header files inclusion scheme. Right now,
|
||||
a client application can do something like this:
|
||||
|
||||
#include <ft2build.h> -- include build and setup configuration file
|
||||
#include FT_FREETYPE_H -- main API file
|
||||
#include FT_GLYPH_H -- abstract glyph image handling, etc..
|
||||
|
||||
I. CHANGES TO THE MODULES / FONT DRIVERS:
|
||||
|
||||
- THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to
|
||||
avoid legal problems with the Apple patents. It seems that we
|
||||
mistakenly turned this option on in previous releases of the build.
|
||||
|
||||
note that if you want to use the bytecode interpreter, in order to
|
||||
get high-quality TrueType rendering, you'll need to toggle by hand
|
||||
the definition of the TT_CONFIG_OPTION_BYTECODE_INTERPRETER macro
|
||||
in the file "include/freetype/config/ftoption.h"
|
||||
|
||||
- The CFF driver has been improved by Tom Kacvinsky:
|
||||
|
||||
* support for "seac" emulation
|
||||
* support for "dotsection"
|
||||
* support for retrieving glyph names through "FT_Get_Glyph_Name"
|
||||
|
||||
The first two items are necessary to correctly a large number of
|
||||
Type 1 fonts converted to the CFF formats by Adobe Acrobat.
|
||||
|
||||
|
||||
- the Type 1 driver was also improved by Tom:
|
||||
|
||||
* better EM size computation
|
||||
* better support for synthetic (transformed) fonts
|
||||
* the Type 1 driver returns the charstrings corresponding to
|
||||
each glyph in the "glyph->control_data" field after a call to
|
||||
"FT_Load_Glyph"
|
||||
|
||||
|
||||
- various other bugfixes, including the following:
|
||||
|
||||
* fixed a nasty memory leak in the Type 1 driver
|
||||
|
||||
* the autohinter and the pcf driver used static writable data
|
||||
when they shouldn't
|
||||
|
||||
* many casts were added to make the code more 64-bits safe.
|
||||
it also now compiles on Windows XP 64-bits without warnings
|
||||
|
||||
* some incorrect writable statics were removed in the "autohint"
|
||||
and "pcf" drivers. FT2 now compiles on Epoc again..
|
||||
|
||||
|
||||
II. CHANGES TO THE HIGH-LEVEL API
|
||||
|
||||
- the library header files inclusion scheme has been changed. The old
|
||||
scheme looked like:
|
||||
|
||||
#include <freetype/freetype.h>
|
||||
#include <freetype/ftglyph.h>
|
||||
#include <freetype/ftcache.h>
|
||||
#include <freetype/cache/ftimage.h>
|
||||
|
||||
use:
|
||||
|
||||
#include <ft2build.h>
|
||||
#include FT_FREETYPE_H
|
||||
#include FT_GLYPH_H
|
||||
#include FT_CACHE_H
|
||||
#include FT_CACHE_IMAGE_H
|
||||
|
||||
NOTE THAT THE OLD INCLUSION SCHEME WILL STILL WORK WITH THIS RELEASE.
|
||||
HOWEVER, WE DON'T GUARANTEE THAT THIS WILL STILL BE TRUE IN THE NEXT
|
||||
ONE (A.K.A. FREETYPE 2.1)
|
||||
|
||||
the file <ft2build.h> is used to define the header filename macros.
|
||||
The complete and commented list of macros is available in the API
|
||||
reference under the section name "Header File Macros" in Chapter I.
|
||||
|
||||
- many, many comments have been added to the public source file in
|
||||
order to automatically generate the API Reference through the
|
||||
"docmaker.py" Python script.
|
||||
|
||||
The latter has been updated to support the grouping of sections
|
||||
in chapters, and better index sort. See:
|
||||
|
||||
http://www.freetype.org/freetype2/docs/reference/ft2-toc.html
|
||||
|
||||
|
||||
III. CHANGES TO THE BUILD PROCESS
|
||||
|
||||
|
||||
- if you're not building FreeType 2 with our own build system (i.e. with
|
||||
your own Makefiles or project files), you'll need to be aware that the
|
||||
build process as changed a little bit. Namely:
|
||||
|
||||
- you don't need to put the "src" directory in the include path
|
||||
when compiling any FT2 component
|
||||
|
||||
- instead, simply put the component's directory in the current
|
||||
include path.
|
||||
|
||||
So, if you were doing something like:
|
||||
|
||||
cc -c -Iinclude -Isrc src/base/ftbase.c
|
||||
|
||||
change the line to:
|
||||
|
||||
cc -c -Iinclude -Isrc/base src/base/ftbase.c
|
||||
|
||||
|
||||
If you were doing something like:
|
||||
|
||||
cd src/base
|
||||
cc -c -I../../include -I.. ftbase.c
|
||||
|
||||
change it to:
|
||||
|
||||
cd src/base
|
||||
cc -c -I../../include ftbase.c
|
||||
|
||||
|
||||
- the build system has changed slightly when compiling by hand (either
|
||||
from the command line or from an IDE). You don't need to put the "src"
|
||||
directory in the include path anymore. Rather, place each component's
|
||||
path.. See INSTALL and "docs/BUILD" for details..

@ -2,11 +2,11 @@ Here is a list of items that need to be addressed in FreeType 2:
|
|||
|
||||
* Add synthesized Unicode charmap processing to the CFF driver.
|
||||
|
||||
* Investigate usage of casts and bit width of integer types used. The idea is
|
||||
to typedef FT_Fixed, FT_Long, FT_Int, etc. to use the appropriate built in
|
||||
integer types. This is so that we may avoid unnecessary explict typecasts
|
||||
and side affects inherent in implict casts. This is mostly an issue on
|
||||
platforms where long integers are 64 bits wide (instead of 32 bits wide).
|
||||
* Fix Visual C++ project file
|
||||
|
||||
* Fix a bug in the TrueType driver: linear horizontal advances of composites
|
||||
are not returned properly.
|
||||
|
||||
* Change the build system to work with the "Jam" tool instead of the
|
||||
terribly complex and error-prone GNU Makefiles we're currently using
|
||||
|
||||
* Fix exact bbox calculation. The current code uses an iterative algorithm
|
||||
which can fail miserably.
