Class ImageColorbar

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              jsky.image.gui.ImageColorbar

All Implemented Interfaces:

java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.swing.event.MouseInputListener

public class ImageColorbar
extends javax.swing.JComponent
implements javax.swing.event.MouseInputListener

This widget displays a color bar with the colors used in the image and allows you to manipulate the color lookup table by dragging the mouse over the bar (based on the JAITutor demo by Dennis Sigel).
