Snapshot 0.1.6 (2005-07-28 Carl Worth <cworth@cworth.org>)
|
|

==========================================================
|
|
|
|
|
Behavioral changes
|
|
|
|
|
------------------
|
|
|
|
|
Clips are changed to only affect destination operands, not
|
|
|
|
|
sources. This gives the desired behavior for cairo. If the X server's
|
|
|
|
|
Render implementation wants to use pixman it will have to select
|
|
|
|
|
source clipping, (presumably through a new API call that we can add at
|
|
|
|
|
that point).
|
|
|
|
|
|
|
|
|
|
Bug fixes
|
|
|
|
|
---------
|
|
|
|
|
Fix leak of the clip region associated with an image in
|
|
|
|
|
pixman_image_destroy.
|
|
|
|
|
|
|
|
|
|
Fix units for stride return to be FbStip-sized, (this bug was causing
|
|
|
|
|
non antialiased text in cairo to appear as garbage).
|
|
|
|
|
|
|
|
|
|
Other changes
|
|
|
|
|
-------------
|
|
|
|
|
The implementation has been merged considerably with xserver/fb. Most
|
|
|
|
|
of the merge was just name changes, but there were likely some bug
|
|
|
|
|
fixes or performance improvements in there as well.

|
|
==========================================================
|
|
|
|
|
Bug fixes
|
|
|
|
|
---------
|
|
|
|
|
Fix confusion of depth and bpp which was causing cairo to crash on
|
|
|
|
|
some X servers.
|
|
|
|
|
|
|
|
|
|
Properly declare pixman_fixed16_16_t as int32_t which fixes
|
|
|
|
|
compilation failures on some platforms.
|
|
|
|
|
|
|
|
|
|
Fix to find inttypes.h on AIX.
|
|
|
|
|
|
|
|
|
|
Fix bug in compositing when the source image has no alpha channel.
|
|
|
|
|
|
|
|
|
|
Some fixes to the clipping code.
|
|
|
|
|
|
|
|
|
|
Fix memory leak when asked to draw a degenerate trapezoid list.

|
==========================================================
|
|
|

|
API Addition
|
|
|
|
|
------------
|
|
|
|
|
Add new function:
|
|
|
|
|
|
|
|
|
|
void
|
|
|
|
|
pixman_add_trapezoids (pixman_image_t *dst,
|
|
|
|
|
int x_off,
|
|
|
|
|
int y_off,
|
|
|
|
|
const pixman_trapezoid_t *traps,
|
|
|
|
|
int ntraps);
|
|
|
|
|
|
|
|
|
|
Performance improvement
|
|
|
|
|
-----------------------
|
|
|
|
|
Restrict size of intermediate surface used while compositing
|
|
|
|
|
trapezoids based on the bounds of the desination surface.
|
|
|
|
|
|
|
|
|
|
Bug fixes
|
|
|
|
|
---------
|
|
|
|
|
Fix rendering on 64-bit platforms.

Performance improvements
|
|
|
|
|
------------------------
|
|
|
|
|
Solid fills are now much faster, (thanks to Alexander Larsson).
|
|
|
|
|
|
|
|
|
|
Bug fixes
|
|
|
|
|
---------
|
|
|
|
|
Fixed to quiet warnings in newer versions of gcc.
|
|
|
|
|
|
|
|
|
|
Don't divide-by-zero if given an image of size 0x0.
|
|
|
|
|
|
|
|
|
|
Fixed several corner cases where values outside a trapezoid would be
|
|
|
|
|
drawn with alpha 1/255 (in the 8-bit case).
|
|
|
|
|
|
|
|
|
|
Internal changes
|
|
|
|
|
----------------
|
|
|
|
|
Imported the newer point-sampling trapezoid rasterization code that
|
|
|
|
|
Keith Packard wrote for the X server. This provide pixel-perfect
|
|
|
|
|
matching with the Render extension as well as code that is simpler,
|
|
|
|
|
more robust, and easier to maintain.

Snapshot 0.1.2 (2004-10-27 Carl Worth <cworth@cworth.org>)
|
|
|
|
|
==========================================================
|
|
|
|
|
New functionality
|
|
|
|
|
-----------------
|
|
|
|
|
Added three new functions:
|
|
|
|
|
|
|
|
|
|
pixman_image_set_component_alpha
|
|
|
|
|
pixman_format_get_masks
|
|
|
|
|
pixman_image_get_format
|
|
|
|
|
|
|
|
|
|
The first enables component-alpha compositing which can be used for
|
|
|
|
|
optimizing sub-pixel rendering of text and other geometry. This is
|
|
|
|
|
useful when the geometrical relationship of the sub-pixel components
|
|
|
|
|
of the display device are known, (eg. with flat-panel monitors rather
|
|
|
|
|
than CRTs).
|
|
|
|
|
|
|
|
|
|
The other two functions are simple query functions that were missing.
|
|
|
|
|
|
|
|
|
|
Bug fixes
|
|
|
|
|
---------
|
|
|
|
|
Enabling both transform and repeat simultaneously now works.
|
|
|
|
|
Some byte-order fixes.
|
|
|
|
|
Clipping fixes: pixman now takes a copy of the client clipping region
|
|
|
|
|
client clipping is now actually used, it wasn't earlier.
|

Build fixes for cygwin
|
|
|
|
|
----------------------
|
|
|
|
|
This snapshot adds the -no-undefined flag during compilation which is
|
|
|
|
|
necessart for building a shared library under cygwin.
|
|
|
|
|
|
|
|
|
|
Cleanup of the public API
|
|
|
|
|
-------------------------
|
|
|
|
|
We recently noticed that there were a coupld of bugs in the script
|
|
|
|
|
that renamed libic to libpixman. Fixing this requires the following
|
|
|
|
|
changes in the public API:
|
|
|
|
|
|
|
|
|
|
PIXMAN_FORMAT_AR_GB32 -> PIXMAN_FORMAT_ARGB32
|
|
|
|
|
PIXMAN_FORMAT_RG_B24 -> PIXMAN_FORMAT_RGB24
|
|
|
|
|
|
|
|
|
|
While we're changing that, we also normalized the names of structure
|
|
|
|
|
tags, for example:
|
|
|
|
|
|
|
|
|
|
struct _pixman_region16_t -> struct pixman_region16
|
|
|
|
|
etc.
|
|
|
|
|
|
|
|
|
|
but users are expected to use typedefs such as pixman_region16_t
|
|
|
|
|
anyway.
|
