- I am having trouble using SetPortPix. I want to temporarily
- set the portpixmap to an offscreen pixmap, do some drawing there, and
- then switch back to do normal screen drawing again. I've
- done this with bitmaps and SetPortBits, but am having troubles with
- pixmaps. I think my trouble might be just in grabbing the original
- portpix before switching it. It's a handle (unlike portbits), and I'm
- a little confused as to how to deal with it.
- I just want to have a global pixmaphandle which i can always pass to
- SetPortPix to resume screen drawing.
-
- confused and appreciative of any help,
- pat
