Re: animate
Hello Patrick -
As far as creating animations on your Linux system goes, I think you'll find that
the reason you are getting blank pages after the first image is drawn is because
your Xserver isn't using backing store. If you do a "xdpyinfo", you should see a
line like:
options: backing-store YES, save-unders YES
Except in your case, I believe both options will be "NO". When starting the
Xserver, you'll want to make sure that the option "+bs" is used - this will turn on
the backing store and enable you to see the animations on your Linux machine.
I'm not sure what is going on with the Alpha/OSF problem - I will look into that...
Let me know if you have any questions -
