Class ImageImposter

java.lang.Object
  java.awt.Image
      cytoscape.render.export.ImageImposter

public final class ImageImposter
extends Image

The primary purpose of this class is to enable an arbitrary Graphics object to receive rendering calls from a cytoscape.render.immed.GraphGraphics instance. This, in turn, can be used to render a graph directly to a scalar vector graphic.

public ImageImposter(Graphics graphics,
                     int width,
                     int height)
