public class JUImageControl

extends javax.swing.JPanel

implements java.awt.event.ActionListener, java.awt.event.FocusListener, JUDefaultControlInterface

Implements a data-aware Image Control. JUImageControl can be bound to BC4J row attributes. The ImageControl treats the data stream as an image (JPEG or GIF) and displays it.
