public class JPanelVolOpacityRGB
extends JPanelVolOpacityBase

Deprecated.

This class produces a frame where the histogram of the image data is displayed using the color mapping. All frames using the color map are dynamically updated with the new color map. This is the color image volume opacity control panel. In addition to the JPanelColorHisoRGB, the panel hold the gradient magnitude hisogram control panel.

Version:

1.0
