# Class PostscriptWriter

java.lang.Object
weka.gui.visualize.JComponentWriter
weka.gui.visualize.PostscriptWriter

public class PostscriptWriter extends JComponentWriter
This class takes any Component and outputs it to a Postscript file.

Note:
This writer does not work with Components that rely on clipping, like e.g. scroll lists. Here the complete list is printed, instead of only in the borders of the scroll list (may overlap other components!). This is due to the way, clipping is handled in Postscript. There was no easy way around this issue. :-(
