LabColorSpace Class

A CIE Lab* (Lab) color space in a PDF document.

Declaration

public class LabColorSpace extends ColorSpace

Remarks

The Lab color space is device-independent and describes colors using three components: lightness (L), green-red (a), and blue-yellow (b). It uses a white point to define the reference illuminant and can optionally specify a black point and valid ranges for the a and b* components.
