Examples of LabelFigure

diva.canvas.toolbox.LabelFigure
A figure which draws a string. If the string contains newlines, then it will be broken up into multiple lines. Strings can be "anchored" in the center or on one of the edges or corners, so that when the font or text changes, the label appears to stay in the right location. @author Michael Shilman @author John Reekie @version $Id: LabelFigure.java,v 1.16 2005/07/08 19:54:58 cxh Exp $
