thanks a lot for the tip - I'll have a look how much speed improvement
I can get.
However for what I want to do I think Xvfb is quite better - since
thanks to its system-ram based nature its very fast and even allows
direct access through its files.
However Xvfb stores its screen in a format called "XWD X Window Dump
image data, "Xvfb lukihost:1.0", 1024x768x24" - however I was not able
to find a format-description so that I can read this file into a
default int using default file/io.
Any ideas where to find informations regarding the format of this image?
Thanks, lg Clemens
