Hi There,
I have a bit of X11 code that I've compiled on both a linux machine
(with XFree86 Version 3.3.6 / X Window System) and
and a mac running apple's x11 implementation. The code is the Open
Dynamics Engine (www.ode.org), if you're interested.
Anyhow, they've built rudimentary frame-grabbing of openGL rendered
windows via XGetImage. This works fine on the linux machine, but on the
mac all of the images are blank (0 values). What distinction is there
between the two X11 servers that might cause this?
Thanks,
John
