Thanks - I tried your suggestion with the following code and it had some success. The OMPoly rotates, but it puts it at random locations on the map. (I tried to clone Graphics g, but I get an error saying that method is protected). polyLat and polyLon are the latitude and longitude of the OMPoly. Am I missing something?

_at_Override
public void render(Graphics g){
Graphics2D image = (Graphics2D) g;
AffineTransform transform = image.getTransform();
transform.rotate(Math.toRadians(45),polyLat,polyLon);
image.transform(transform);
super.render((Graphics) image);
}

Hi Pat,
There's really no support built-in for rotating OMPolys, but you can
do that easily by extending OMPoly and overriding the render(Graphics)
method. Create a clone of the Graphics object, rotate it, and then
call super.render(Graphics). Don't forget to dispose of the clone
when you are done.
The only other thing you'll have to decide is where to center the
rotation of the Graphics object, and you can use the location of the
poly for that.
Hope this helps,
Don
