Convert CIELAB to CIEXYZ

Description

L, A, and B specify the values in the three coordinates of the CIELAB color space, XN, YN, and ZN allow to specify additional CIE chromaticities to specify a specific white point.

Usage

colorlib.LAB_to_XYZ(L, A, B, XN=None, YN=None,
                    ZN=None)

Arguments

Lnumpy.ndarray: Values for the L dimension.
Anumpy.ndarray: Values for the A dimension.
Bnumpy.ndarray: Values for the B dimension.
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 as a list of numpy.ndarrays of the same length as the inputs ([X, Y, Z]).
