I'm confusing the per-pixel alpha blending.
My OSD plane is over video plane. the background of OSD plane is covered
by a picture, which alphas are all 1. and then I blend another picture
on the backgound. This picture is created by photoshop and some alphas
are belong to (0, 1). I want to see the backgound, you know. But the
result is, I see the video plane.
What's happened and how to do it ?
I'm using Qt 4.5.1, and DFB 1.2.6.
Thanks!

Hi, guys,
I'm working directfb to support QT plugin. Some bugs are found
out and some issues still confusing me. If you are working on this
path, or you are interesting it, or you are an expert, Pls. reply
this mail, and let's talk.
BTW: Could anyone provide some good reference documents for the
architecture of DFB? I mean the design, not only the interfaces.
Thanks!
