Hello,
The ProjectionPainter interface is used by the
com.bbn.openmap.image.ImageServer, to create images from the layers.
If you want the layer to paint new information, I suggest you make
your layer extend the OMGraphicHandlerLayer, and override the prepare
() method, returning an OMGraphicList with the OMGraphics you want on
it. Use the DemoLayer as an example.
Hope this helps,
Don
