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. + +Snapshot 0.1.5 (2005-05-18 Carl Worth <cworth@cworth.org>) +========================================================== +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. + +Snapshot 0.1.4 (2005-03-07 Carl Worth <cworth@cworth.org>) +========================================================== +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. + +Snapshot 0.1.3 (2005-01-21 Carl Worth <cworth@cworth.org>) +========================================================== +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. + +Snapshot 0.1.1 (2004-04-16 Carl Worth <cworth@east.isi.edu>) +============================================================ +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. |
