Class LabColorSpace

java.lang.Object

java.awt.color.ColorSpace

imagingbook.pub.color.image.LabColorSpace

All Implemented Interfaces:

Serializable

public class LabColorSpace
extends ColorSpace

This class implements the CIELab color space. Conversion from/to sRGB is implemented directly through D65-based XYZ coordinates, i.e., without conversion to Java's D50-based profile connection space. The methods fromCIEXYZ/toCIEXYZ still return D50-based XYZ coordinates in Java's profile connection space.
