LATEST CHANGES BETWEEN 2.1.0 and 2.0.9
I. IMPORTANT BUG FIXES
- The TrueType bytecode interpreter has been fixed to produce
_exactly_ the same output as FreeType 1.x. Previous differences
were due to slightly distinct fixed-point computation routines
used to perform dot products and vector length measurements.
It seems that native TrueType hinting is _extremely_ sensitive
to rounding errors. The required vector computation routines have
been optimized and placed within the "ttinterp.c" file.
II. NEW FEATURES
- The 'configure' script used on Unix systems has been modified to
check that GNU Make is being used to build the library. If not,
it will display a message proposing to use the GNUMAKE environment
variable to name it..
The Unix-specific file README.UNX has been modified accordingly
III. MISCELLANEOUS
- The FreeType License in 'docs/FTL.txt' has been updated to include
a proposed preffered disclaimer. If you're using FreeType in your
products, you're encouraged (but not mandated) to use the following
text in your documentation:
"""
Portions of this software are copyright © 1996-2002 The FreeType
Project (www.freetype.org). All rights reserved.
"""
- The default size of the render pool has been reduced to 16 Kb. This
shouldn't result in any noticeable performance penalty, unless you're
using the engine as-is to render very large and complex glyphs..
- The FreeType 2 Re-Design has begun. More information can be found
at the following web address:
http://www.freetype.org/freetype2/redesign.html
The following internal changes have been performed within the sources
of this release:
- many internal types have been renamed to increase consistency.
the following should be true, except for public types:
* all structure types have a name ending in "Rec" (short for
'record').
* a pointer-to-structure type has the same name than the
structure, _without_ the "Rec" suffix.
for example:
typedef struct FooRec_
{
....
} FooRec, *Foo;
- many internal macros have been renamed to increase consistency.
the following should be true:
* all macros have a name beginning in "FT_". This required
a few changes like:
ALLOC => FT_ALLOC
FREE => FT_FREE
REALLOC => FT_REALLOC
* all macro are completely UPPERCASE. This required a few
changes like:
READ_Short => FT_READ_SHORT
NEXT_Short => FT_NEXT_SHORT
GET_ULongLE => FT_GET_ULONG_LE
MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
etc..
* whenever possible, all macro names follow the FT_<OBJECT>_<METHOD>
pattern. For example:
ACCESS_Frame => FT_FRAME_ENTER
FORGET_Frame => FT_FRAME_EXIT
EXTRACT_Frame => FT_FRAME_EXTRACT
RELEASE_Frame => FT_FRAME_RELEASE
FILE_Pos => FT_STREAM_POS
FILE_Seek => FT_STREAM_SEEK
FILE_Read => FT_STREAM_READ
FILE_ReadAt => FT_STREAM_READ_AT
READ_Fields => FT_STREAM_READ_FIELDS
- many internal functions have been renamed to follow the
FT_<Object>_<Method> pattern. For example:
FT_Seek_Stream => FT_Stream_Seek
FT_Read_Stream_At => FT_Stream_ReadAt
FT_Done_Stream => FT_Stream_Close
FT_New_Stream => FT_Stream_Open
FT_New_Memory_Stream => FT_Stream_OpenMemory
FT_Extract_Frame => FT_Stream_ExtractFrame
note that method names do not contain "_".
- the FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been removed and
are now replaced by FT_NEW_ARRAY and FT_RENEW_ARRAY which do
not take a type as the fourth argument. Instead, the array
element type size is computed automatically from the type
of the target pointer used.
- a new object class, named FT_CMap has been introduced. These
internal objects are used to model character maps. This eases
the support of additional charmap types within the engine
- a new configuration file named "ftstdlib.h" has been added
to 'include/freetype/config'. It is used to define aliases
for _every_ routine of the ISO C library that the font engine
uses. Each aliases has a "ft_" prefix (e.g. "ft_strlen" is an
alias for "strlen").
this is used to ease the porting of FT2 to exotic runtime
environments where the ISO C Library isn't available (e.g.
XFree86 extension modules).
More details are available in the "ChangeLog" file.
