Struct kolor_64::ColorSpace

pub struct ColorSpace { /* fields omitted */ }

See spaces for defined color spaces.

ColorSpace assumes that a color space is one of

• the CIE XYZ color space
• an RGB color space
• an invertible mapping from one the above (TransformFn)

An example of a TransformFn is the sRGB “opto-eletronic transfer function”, or “gamma compensation”.

kolor makes the distinction between “linear” and “non-linear” color spaces, where a linear color space can be defined as a linear transformation from the CIE XYZ color space.

ColorSpace contains a reference WhitePoint to represent a color space’s reference illuminant.

A linear RGB ColorSpace can be thought of as defining a relative coordinate system in the CIE XYZ color coordinate space, where three RGB primaries each define an axis pointing from the black point (0,0,0) in CIE XYZ. Non-linear ColorSpaces - such as sRGB with gamma compensation applied - are defined as a mapping from a linear ColorSpace’s coordinate system.
