Release 1.0.0 (2005-08-24 Carl Worth <cworth@cworth.org>)
|
||||
=========================================================
|
||||
Experimental backends
|
||||
---------------------
|
||||
* The PS, PDF, Quartz, and XCB backends have been declared
|
||||
experimental, and are not part of the API guarantees that accompany
|
||||
this release. They are not built by default, even when the required
|
||||
libraries are available, and must be enabled explicitly with
|
||||
--enable-ps, --enable-pdf, --enable-quartz or --enable-xcb.
|
||||
|
||||
It is very painful for us to be pushing out a major release without
|
||||
these backends enabled. There has been a tremendous amount of work
|
||||
put into each one and all are quite functional to some
|
||||
extent. However, each also has some limitations. And none of these
|
||||
backends have been tested to the level of completeness and
|
||||
correctness that we expect from cairo backends.
|
||||
|
||||
We do encourage people to experiment with these backends and report
|
||||
sucess, failure, or means of improving them.
|
||||
|
||||
Operator behavior
|
||||
-----------------
|
||||
* Prior to 0.9.0 the SOURCE, CLEAR and a number of other operators
|
||||
behaved in an inconsistent and buggy fashion and could affect areas
|
||||
outside the clip mask. In 0.9.0, these six "unbounded" operators
|
||||
were fixed to consistently clear areas outside the shape but within
|
||||
the clip mask. This is useful behavior for an operator such as IN,
|
||||
but not what was expected for SOURCE and CLEAR. So, in this release
|
||||
the behavior of SOURCE and CLEAR has been changed again. They now
|
||||
affect areas only within both the source and shape. We can write
|
||||
the new operators as:
|
||||
|
||||
SOURCE: dest' = (mask IN clip) ? source : dest
|
||||
CLEAR: dest' = (mask IN clip) ? 0 : dest
|
||||
|
||||
Behavior and API changes
|
||||
------------------------
|
||||
* Setting the filter on a gradient pattern would change the
|
||||
interpolation between color stops away from the normal linear
|
||||
interpolation. This dubious behavior has been removed.
|
||||
|
||||
* The CAIRO_CONTENT_VALID() and CAIRO_FORMAT_VALID() macros --
|
||||
implementation details that leaked into cairo.h -- have been moved
|
||||
into an internal header.
|
||||
|
||||
* The cairo_show_text function now advances the current point
|
||||
according to the total advance values of the string.
|
||||
|
||||
Features
|
||||
--------
|
||||
* When compiled against recent versions of fontconfig and FreeType,
|
||||
artificial bold fonts can now be turned on from fonts.conf using
|
||||
the FC_EMBOLDEN fontconfig key.
|
||||
|
||||
Optimization
|
||||
------------
|
||||
* The compositing code from the 'xserver' code tree has now been
|
||||
completely merged into libpixman. This includes MMX optimization of
|
||||
common operations.
|
||||
|
||||
* The image transformation code in libpixman has been improved and
|
||||
now performs significantly faster.
|
||||
|
||||
Bug fixes
|
||||
---------
|
||||
* Several crashes related to corruption in the font caches have been
|
||||
fixed.
|
||||
|
||||
* All test cases now match pixel-for-pixel on x86 and PPC; this
|
||||
required fixing bugs in the compositing, stroking, and pattern
|
||||
rendering code.
|
||||
|
||||
* Negative dash offsets have been fixed to work correctly.
|
||||
|
||||
* The stroking of paths with mutiple subpaths has now been fixed to
|
||||
apply caps to all subpaths rather than just the last one.
|
||||
|
||||
* Many build fixes for better portability on various systems.
|
||||
|
||||
* Lots of other bug fixes, but we're too tired to describe them in
|
||||
more detail here.

|

=============
|
||||
Cairo is a 2D graphics library with support for multiple output
|
||||
devices. Currently supported output targets include the X Window
|
||||
System, OpenGL, and win32 as well as image buffers and PostScript and
|
||||
PDF files.

System, OpenGL, and win32 as well as image buffers. Experimental

|

|

Cairo is designed to produce consistent output on all output media
|
||||
while taking advantage of display hardware acceleration when available
