[Pixman] [PATCH 2/6] Add a test program for pixman_composite_trapezoids().

From: Søren Sandmann Pedersen s...@redhat.com A CRC32 based test program to check that pixman_composite_trapezoids() actually works. --- test/Makefile.am|5 + test/composite-traps-test.c | 253 +++ 2 files changed, 258 insertions(+), 0

[Pixman] [PATCH 3/6] Add support for triangles to pixman.

From: Søren Sandmann Pedersen s...@redhat.com The Render X extension can draw triangles as well as trapezoids, but the implementation has always converted them to trapezoids. This patch moves the X server's triangle conversion code into pixman, where we can reuse the pixman_composite_trapezoid()

[Pixman] [PATCH 5/6] Optimize adding opaque trapezoids onto a8 destination.

From: Søren Sandmann Pedersen s...@redhat.com When the source is opaque and the destination is alpha only, we can avoid the temporary mask and just add the trapezoids directly. --- pixman/pixman-trap.c | 133 - 1 files changed, 76 insertions(+),

[Pixman] [PATCH 6/6] Add new public function pixman_add_triangles()

From: Søren Sandmann Pedersen s...@redhat.com This allows some more code to be deleted from the X server. The implementation consists of converting to trapezoids, and is shared with pixman_composite_triangles(). --- pixman/pixman-trap.c | 61 -

[Pixman] [PATCH 2/3] Move miTriangles to fb as fbTriangles().

From: Søren Sandmann Pedersen s...@redhat.com The fb version simply calls the new pixman_composite_triangles(). This allows us to get rid of miCreateAlphaPicture(). Signed-off-by: Søren Sandmann s...@redhat.com --- fb/fbpict.c |1 + fb/fbpict.h | 10 + fb/fbtrap.c | 109

[Pixman] [PATCH 3/3] Implement fbAddTriangles() in terms of pixman_add_triangles().

From: Søren Sandmann Pedersen s...@redhat.com This allows the remaining triangle-to-trap conversion code to be deleted. Signed-off-by: Søren Sandmann s...@redhat.com --- fb/fbtrap.c | 91 ++- 1 files changed, 9 insertions(+), 82

Re: [Pixman] needing user_manual of pixman(渴望得到pixman的用户手册)
