Hi - my hardware supports two frame buffers, one overlaid upon the other. I can independently adjust the transparency factor of one of the frame buffers. What I'd like to do is:

- draw QImage "A" into fb0
- draw QImage "B" into fb1, with fb1's opacity set to 0 (fully transparent)
- increase the opacity of fb1 to 255 (fully opaque) on a QTimeLine, for a smooth transition from image A to image B

Is there a way to direct QT to support more than one frame buffer?
