PYME.misc.colorsys module

Conversion functions between RGB and other color systems.

This modules provides two functions for each color system ABC:

rgb_to_abc(r, g, b) –> a, b, c abc_to_rgb(a, b, c) –> r, g, b

All inputs and outputs are triples of floats in the range [0.0...1.0] (with the exception of I and Q, which covers a slightly larger range). Inputs outside the valid range may cause exceptions or invalid outputs.

Supported color systems: RGB: Red, Green, Blue components YIQ: Luminance, Chrominance (used by composite video signals) HLS: Hue, Luminance, Saturation HSV: Hue, Saturation, Value

hacked from the original colorsys module to work with numpy arrays
