diva.canvas.toolbox.BasicFigure
A BasicFigure is one that contains a single instance of Shape. The figure can have a fill with optional compositing (for translucency), and a stroke with a different fill. With this class, simple objects can be created on-the-fly simply by passing an instance of java.awt.Shape to the constructor. This class is mainly intended for use for simple open and closed shapes. For more complex Figures, use the VectorFigure class. @version $Id: BasicFigure.java,v 1.20 2006/03/28 23:55:54 cxh Exp $ @author John Reekie @author Nick Zamora
