Hi,
I am trying to do this same thing. However, I get the following error shown
in the stack trace. Does anyone have any ideas? I am not using this with
any GUI code, but rather as a backend process to extract an image from a
shapefile. Is there something special I need to setup in my map?
Thanks,
Cliff
