Class PostscriptGraphics

java.lang.Object
java.awt.Graphics
java.awt.Graphics2D
weka.gui.visualize.PostscriptGraphics
public class PostscriptGraphics extends Graphics2D
The PostscriptGraphics class extends the Graphics2D class to produce an encapsulated postscript file rather than on-screen display.

Currently only a small (but useful) subset of Graphics methods have been implemented. To handle the ability to Clone a Graphics object, the graphics state of the eps is set from the graphics state of the local PostscriptGraphics before output. To use, create a PostscriptGraphics object, and pass it to the PaintComponent method of a JComponent.

If necessary additional font replacements can be inserted, since some fonts might be displayed incorrectly.
