Thanks MD. I don't know when I'll get to this, but when I get it done I'll make the code available to others. Would you be willing to add a method to the Envelope class whose signature looks something like this?:
public List<Envelope> subdivideEnvelope(int rows, int columns) If you don't think this is a good addition, then I'll park it in my own utility class.
