public class CalRGBColorSpace
extends ColorSpace

A calibrated RGB color space. A CalRGB color space (Red, Green, Blue) is a CIE-based ABC color space with only one transformation stage instead of two.

In this type of space, A, B, and C represent calibrated red, green, and blue color values. These three color components must be in the range 0.0 to 1.0; component values falling outside that range are adjusted to the nearest valid value without error indication.

CalRGBColorSpace

public CalRGBColorSpace(List<Double> whitePoint,
 List<Double> blackPoint,
 List<Double> gamma,
 List<Double> matrix)

Create a CalRGB color space.

Parameters:

whitePoint - 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 - 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.

gamma - An array of three numbers [ GR GG GB ] specifying the gamma for the red, green, and blue (A, B, and C) components of the color space.

matrix - An array of nine numbers [ XA YA ZA XB YB ZB XC YC ZC ] specifying the linear interpretation of the decoded A, B, and C components of the color space with respect to the final XYZ representation.

CalRGBColorSpace

public CalRGBColorSpace(List<Double> whitePoint)

Create a CalRGB color space.

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

The gamma defaults to [1.0, 1.0, 1.0].

The matrix defaults to [1 0 0 0 1 0 0 0 1]

Parameters:

whitePoint - 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.

getWhitePoint

public List<Double> getWhitePoint()

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.

getBlackPoint

public List<Double> getBlackPoint()

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.

getGamma

public List<Double> getGamma()

A number G defining the gamma for the gray component. G must be positive and is generally greater than or equal to 1.

getMatrix

public List<Double> getMatrix()

An array of nine numbers [ XA YA ZA XB YB ZB XC YC ZC ] specifying the linear interpretation of the decoded A, B, and C components of the color space with respect to the final XYZ representation.
