Description:

Calculates white point corresponding to neutral color in camera color space based on two known color matrices corresponding to different light conditions.

If only one color matrix is known, pass null (Nothing) to XYZToCam2.

Dimensions of XYZToCam1 and XYZToCam2 must be equal to (n, 3); length of NeutralColor array must be equal to n, where n is channel count of native camera color space (3 or 4).

Syntax:

      CalculateCameraWhitePoint (
        XYZToCam1 As IGDoubleMatrix,    
        Illuminant1 As enumIGIlluminant,        
        XYZToCam2 As IGDoubleMatrix,            
        Illuminant2 As enumIGIlluminant,        
        NeutralColor As IGDataArray 
        ) As IGDoublePoint

Parameters:

Name	Description
XYZToCam1	XYZ to camera matrix under Illuminant 1
Illuminant1	Illuminant 1
XYZToCam2	XYZ to camera matrix under Illuminant 2
Illuminant2	Illuminant 2
NeutralColor	Array of Double containing normalized coordinates of a neutral color

Return Value:

Returns the calculated white point coordinates.
