public class HorizonColorModelDisplay

extends java.awt.Panel

implements java.awt.event.ActionListener

Display a HorizonColorModel highlighting the colors representing undefined, underflow, and overflow values.

The display is made up of a HorizonColorBar and three LabeledColors, the latter representing the undefined, underflow, and overflow color values. ColorModels can be passed to this class (via the constructor or the setActiveColorModel() method) in the form of an IndexColorModel or a HorizonColorModel. If the color model reference is of the last kind, the bar will allow the user to mutate the model via mouse drags on the canvas and mouse clicks on the LabeledColors.

Fiddling the color model via the color bar is the same as for the HorizonColorBar. This fiddling comes in two modes: shifting and stretching. Shifting is done by dragging the mouse left or right; this causes the values in the color table to be shifted. By dragging the mouse up or down, one can compress or stretch the array of colors in the color table.

The special colors representing undefined, underflow, and overflow values can be edited by clicking on the corresponding colored box. This will bring up a widget that allows the red, green, blue, and alpha components to be edited.
