Detailed Description

A Lab color space is a CIE-based ABC color space with two transformation stages. In this type of space, A, B, and C represent the L*, a*, and b* components of a CIE 1976 L*a*b* space. The range of the first (L*) component is always 0 to 100; the ranges of the second and third (a* and b*) components are defined by the Range.

Constructor & Destructor Documentation

LabColorSpace

LabColorSpace(java.util.List< Double >whitePoint)

Parameters

whitePoint: java.util.List< Double >

An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.

Create a Lab color space.

The blackPoint defaults to [0.0, 0.0, 0.0].

The range defaults to [-100 100 -100 100]

LabColorSpace

LabColorSpace(java.util.List< Double >whitePoint, java.util.List< Double >blackPoint, java.util.List< Double >range)

Parameters

whitePoint: java.util.List< Double >

An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.

blackPoint: java.util.List< Double >

An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse black point. All three of these numbers must be non-negative.

range: java.util.List< Double >

An array of four numbers [ amin amax bmin bmax ] specifying the range of valid values for the a* and b* (B and C) components of the color space.

Create a Lab color space.
