public class CalGray
extends PColorSpace

A CalGray colour space (PDF 1.1) is a special case of a single-component CIE-based colour space, known as a CIE-based A colour space. This type of space is the one-dimensional (and usually achromatic) analog of CIE-based ABC spaces. Colour values in a CIE-based A space shall have a single component, arbitrarily named A.Figure 23 illustrates the transformations of the A component to X, Y, and Z components of the CIE 1931 XYZ space.
