Create CIELUV Color Object

Description

Creates a color object in the CIELUV color space. Can be converted to: CIEXYZ, CIELUV, CIELAB, RGB, sRGB, polarLAB, and hexcols. Not allowed (ambiguous) are transformations to HSV and HLS.

Usage

CIELUV(L, U, V, alpha=None)

Arguments

Lint, float, list, numpy.array: Numeric value(s) for L dimension.
Uint, float, list, numpy.array: Numeric value(s) for U dimension.
Vint, float, list, numpy.array: Numeric value(s) for L dimension.
alphaNone, float, list, numpy.array: Numeric value(s) for the alpha channel ([0., 1.]) where 0. equals full transparency, 1. full opacity. If None (default) no transparency is added.

Methods

CIELUV.colors(fixup=True, rev=False): Extract Hex Colors
CIELUV.dropalpha(): Remove Alpha Channel
CIELUV.get(dimname=None): Extracting Color Coordinates
CIELUV.get_whitepoint(): Get White Point
CIELUV.hasalpha(): Check for Alpha Channel
CIELUV.hclplot(**kwargs): Palette Plot in HCL Space
CIELUV.length(): Get Number of Colors
CIELUV.set(**kwargs): Set Coordinates/Manipulate Colors
CIELUV.set_whitepoint(**kwargs): Set White Point
CIELUV.specplot(**kwargs): Color Spectrum Plot
CIELUV.swatchplot(**kwargs): Palette Swatch Plot
CIELUV.to(to, fixup=True): Transform Color Space
