How to make Moving Symbols using MapScript

[Stephen Woodbridge]

Vdharan,

Not that I know of. I would be a great extension to Rosa or to Mapplet.
You might want to check on the Rosa list and see if anyone has done
this. If you get something like this working post a note back here
because I would be interested and I'm sure some others would be also.
