Hi John,
Is any part of OpenMap visible to the user, are the layers being used to display anything?
If you don't have a map display, I would use the ImageServer object to create the images for you, it'll use the Layers' renderDataForProjection() methods which allows the layers to process the projection and render the OMGraphics for that projection in a serialized manner.
Hope this helps,
Don
