[comp.sys.amiga] GfxBase->ActiView

ahinds@hvrunix.UUCP (Alexander Hinds) (01/19/88)

	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.
