[comp.sys.mac.programmer] Copy color screen image?

gt4586c@prism.gatech.EDU (WILLETT,THOMAS CARTER) (08/30/90)

I need some help in figuring out how to save the screen image on a
color monitor.  I want to save the current color image, throw up a
dialog box, then restore the original image after the box has gone
away.  Since the dialog box may straddle multiple windows, using
the GetPort routine won't give me access to all the screen.  I've
attempted to get directly to the image from the device record and to
save it using CopyBits, but Think Pascal 3.0 doesn't like you trying
to stuff pixmaps where it wants a bitmap.  Any help would be
greatly appreciated.  thanks.
