Hi Laura,
I think I'd create an ImageServer on the fly, with a Layers[] that you
want to be in the image along with the image formatter you want (like
the AcmeJpegImageFormatter). Then, call imageServer.create(projection)
to get the image bytes, which you can push out to a file.
This method will work for layers that are or are not part of the
current map, although you probably want to be careful of the projection
of the image is different than the image of the map, making sure that
the projection of the layer is set back to the MapBean's projection
before the map gets repainted, if the layer is part of the map.
