Convert CIELUV to CIELAB

Description

L, U, and V 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.LUV_to_XYZ(L, U, V, XN=None, YN=None,
                    ZN=None)

Arguments

Lnumpy.ndarray: Values for the L dimension.
Unumpy.ndarray: Values for the U dimension.
Vnumpy.ndarray: Values for the V 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 ([L, A, B]).
