Create Standard RGB (sRGB) Color Object

Description

Allows conversions to: CIELAB, CIELUV, CIEXYZ, HLS, HSV, RGB, hexcols. polarLAB and polarLUV.

Usage

sRGB(R, G, B, alpha=None, gamma=None)

Arguments

Rint, float, list, numpy.array

Numeric value(s) for red intensity ([0., 1.]).

Gint, float, list, numpy.array

Numeric value(s) for green intensity ([0., 1.]).

Bint, float, list, numpy.array

Numeric value(s) for blue intensity ([0., 1.]).

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.

gammaNone, float

If None (default) the default gamma value is used. Can be specified to overwrite the default.

Examples

from colorspace import sRGB
# Constructing color object with one single color via float
sRGB(1., 0.3, 0.5)

sRGB color object (1 colors)
            R       G       B
  1:     1.00    0.30    0.50

# Constructing object via lists
sRGB([1., 0.8], [0.5, 0.5], [0.0, 0.2])

sRGB color object (2 colors)
            R       G       B
  1:     1.00    0.50    0.00
         0.80    0.50    0.20

# Constructing object via numpy arrays
from numpy import asarray
sRGB(asarray([1., 0.8]), asarray([0.5, 0.5]), asarray([0.0, 0.2]))

sRGB color object (2 colors)
            R       G       B
