Convert RGB to CIEXYZ

Description

R, G, and B give the levels of red, green and blue as values in the interval [0., 1.]. XN, YN, and ZN allow to specify additional CIE chromaticities to specify a specific white point.

Usage

colorlib.RGB_to_XYZ(R, G, B, XN=None, YN=None,
                    ZN=None)

Arguments

Rnumpy.ndarray

Intensities for red ([0., 1.]).

Gnumpy.ndarray

Intensities for green ([0., 1.]).

Bnumpy.ndarray

Intensities for blue ([0., 1.]).

XNNone, numpy.ndarray

Chromaticity of the white point. If of length 1, the white point specification will be recycled if needed. When not specified (all None) a default white point is used.

YN

See XN.

ZN

See XN.

Return

list: Returns corresponding coordinates of CIE chromaticities, a list of numpy.ndarrays of the same length as the inputs ([X, Y, Z]).
