public class EpsGraphics2D
extends Graphics2D

This class provides postscript generation. Use this class just like the Graphics2D class to draw geometric figures. Usage: Process every drawing operation (except redrawing after resizing/restoring the window), coordinate system transformation, color or font setting, clipping, stroke type changing etc. that you perform on the standard graphics object (for screen output) on this class too. This class will save every information necessary for postscript output. Moreover, you can add comments to the postscript source file. If you want to generate the output just call either the toPS() or toEPS() method.
