Class GrayColorModel

java.lang.Object
  java.awt.image.ColorModel
      com.archimed.dicom.image.GrayColorModel

All Implemented Interfaces:

java.awt.Transparency

public class GrayColorModel
extends java.awt.image.ColorModel

This class represents a ColorModel for use with Grayscale images. For images with pixel depth 8, it is possible to use IndexColorModel. But for higher pixel depths, use an int[] for pixeldata in combination with this ColorModel (where the window/level has to be adjustable).
