Method Detail

xyToXyz

public static double[] xyToXyz(double x,
                               double y)

Calculates the XYZ coordinates for a given point (x,y) in the CIE xy-color diagram. XYZ is located on the 3D plane X + Y + Z = 1.

Parameters:

x - x-coordinate

y - y-coordinate

Returns:

the associated XYZ coordinate

xyToXyz

public static double[] xyToXyz(double x,
                               double y,
                               double Y)

xyzToxy

public static double[] xyzToxy(double[] XYZ)

Calculates the (x, y) color diagram coordinates for XYZ color coordinates (X,Y,Z).

Parameters:

XYZ - the XYZ coordinate

Returns:

the xy-coordinate
