Examples of net.sf.jasperreports.engine.JRLineBox

net.sf.jasperreports.engine.JRLineBox
This is useful for drawing borders around text elements and images. Boxes can have borders and paddings, which can have different width and colour on each side of the element. @author Teodor Danciu (teodord@users.sourceforge.net) @version $Id: JRLineBox.java 3033 2009-08-27 11:46:22Z teodord $
