public class RecorderGraphics

extends java.awt.Graphics

Class that extends the awt.Graphics class with a recording functionality. It also makes it possible to save the drawing operations into a file, from which they can be re-read in a standardized way. Image passing at least between Java applications through the clipboard also becomes feasible since the comminucating programs just need to implement this class for understanding each other.
