[comp.windows.x] Need help for accessing the double buffer with Xlib

ii@lezvax.oeaw.ac.at (iinform users) (05/17/91)

We have a Decstation 5000/200PXG with 48 bitplanes (24 bit true color +
24 bit double buffer), running ULTRIX 4.1.  Since we would like to use
the double buffer for some kind of animation, our questions are:

- How is it possible to access the double buffer ?
- How to copy between true-color <---> double-buffer ?
- Can the double buffer be accessed by Xlib calls ?

Any hints are greatly appreciated.
