[Image-SIG] Remove Noise from a National Weather Service Radar Image (.gif)

[J.D. Main]

Hi Fredrik,

You're right about GIF being dead but that's what the Weather Service uses.  
GIF image transparency always works though and that's what I need for this 
application.  I'm placing the Radar images over the top of GIS map layers.

Question:  I tried to use the point method and kept getting errors.  I guess I 
wasn't using proper syntax.  How would you do it?

By the way, PIL is very handy.  Thanks!

J.D.
