I want to Draw on AndRop Mode

There is a background image, foreground image, and mask image.

I want to make a sprite animation program.

so I need function of setRasterop. but there is no setRasterOp in qt4

How can I draw bmp files in AndRop mode?

or How can I implement sprite animation on qt4?

In Qt4 it's called "composition mode". Note that it works only with QImages (on all platforms) and QPixmaps (on X11 and windows).
