BogusColorSpace

public class BogusColorSpace extends ColorSpace
A dummy ColorSpace to enable ColorModel for image data which do not have an innate color representation.

Fields Summary
Constructors Summary
public BogusColorSpace(int numComponents)
Constructs a bogus ColorSpace.

param
numComponents The number of components in the ColorSpace.
exception
IllegalArgumentException if numComponents is less than 1.
