Re: Creating a gif file from a visad display

[Tom Whittaker <tomw@xxxxxxxxxxxxx>]

As a footnote:  Since Unisys holds a patent on the LZW encoding used in 
GIF images, if you are developing this software for commercial purposes, 
you would be required to secure a license from them in order to use GIF 
images (see: http://lpf.ai.mit.edu/Patents/Gif/unisys.html).  At least 
they are no longer going after _everyone_ who generates GIF images...but 
it's still another reason to use PNG.
