Dim colorMatrix2 As IGDoubleMatrix
Dim illuminant2 As ImGearIlluminant
Dim neutralColor() As Double
Dim value As ImGearDoublePoint
 
value = ImGearCameraRawProcessing.CalculateWhitePoint(colorMatrix1, illuminant1, colorMatrix2, illuminant2, neutralColor)

Parameters

colorMatrix1
XYZ to camera colorspace conversion matrix under Illuminant 1.
illuminant1
Illuminant 1.
colorMatrix2
XYZ to camera colorspace conversion matrix under Illuminant 2.
illuminant2
Illuminant 2.
neutralColor
Normalized coordinates of a neutral color.

Return Value

Remarks
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 to >colorMatrix2.

Dimensions of >colorMatrix1 and >colorMatrix2 must be equal to (n, 3), where n is channel count of native camera color space (3 or 4).
