I'm intested in writing a screen blanking program, and I was thinking of using GfxBase->ActiView to get access to the current view and compare it to the previous view (I would have copied the bitmap). However, I have a few questions. If there happens to be two overlapping screens when I get the address of GfxBase->ActiView, how will this figure into the structure? Would they be linked together in View->ViewPort.next? Can I assign the bitmap associated with the view's viewport to a RastPort structure and read the color of a pixel at that location with ReadPixel() (?). I thank you in advance for you help.
