public class ViewJComponentHistoLUT extends ViewJComponentHLUTBase
This class extends the ViewJComponentHLUTBase class and used to coordinate how a histogram and LUT for an image are to be displayed to the screen. For display purposes, this component has a LUT Model. Note y inversion in transfer segment because graphical origin is in upper left corner.
