      • dispose

        public void dispose()
        Description copied from interface: PrintPiece
        Disposes the system resources allocated by this PrintPiece. The dispose method is not a permanent disposal of a PrintPiece. It is intended to reclaim system resources, however future calls to paint(GC,int,int) may require that the resources be allocated again.
        Specified by:
        dispose in interface PrintPiece
