Examples of org.apache.batik.ext.awt.geom.RectListManager

org.apache.batik.ext.awt.geom.RectListManager
RectListManager is a class to manage a list of rectangular regions. This class contains methods to add new rectangles to the List, to merge rectangles in the list (based on a cost function), and functions to subract one RectListManager from another. The main purpose of this class is to manage dirty regions on a display (for this reason it uses Rectangle not Rectangle2D). @author Thomas DeWeese @version $Id: RectListManager.java,v 1.3 2002/02/19 19:22:23 deweese Exp $
