- In a nutshell: Can I change the BitMap of an open SuperBitMap window and
- how do I do it properly?
-
- A program of mine uses a SuperBitMap window to display graphics. I want
- the graphics to be zoomable in/out as well as fast'n'smooth scrolling
- (That's why the SuperBitMap). Now zooming in on the gfx would increase
- its size, so I'd need to switch to a larger BitMap. The question is, can
- the BitMap be changed while Intuition is displaying the window?
-
- As far as I can see, neither RKMs nor autodocs say anything about doing
- something like this. Is it allowed or do I have to have just the
- visible part rendered and render the new visible parts while scrolling?
