Examples of org.apache.batik.gvt.filter.GraphicsNodeRable

org.apache.batik.gvt.filter.GraphicsNodeRable
This interface allows GraphicsNode to be seen as RenderableImages, which can be used for operations such as filtering, masking or compositing. Given a GraphicsNode, a GraphicsNodeRable can be created through a GraphicsNodeRableFactory. @author Vincent Hardy @version $Id: GraphicsNodeRable.java,v 1.5 2004/08/18 07:14:33 vhardy Exp $
