[mapserver-users] How TO: Flashing / Blinking Polygon?

[Stephen Lime]

You need to create an animated gif. Let's say you create a single frame
with the mapserver where the selected polygon is, say, yellow. You could
use GD or ImageMagick to create a second frame changing the yellow to
redm and then yet another tool to wrap the frames into the animated gif. 
What that tool is I don't know but there's got to be one out there, perhaps
ImageMagick. Could do it. Finally that animated gif is returned to the user
and the process continues.

I have an application where the user selects a value from a dropdown menu,
and the corresponding polygon on the map turns red.

I'd like to figure out a way to make the polygon "blink" or "flash" a number
of times in rapid succession, but have absolutely no idea how to do it.

Anyone have any suggestions / examples?

Thanks!
