Class KnownChromaticAdaptationMatrices

Namespace

SixLabors.ImageSharp.ColorProfiles

Assembly

SixLabors.ImageSharp.dll

Provides matrices for chromatic adaptation, facilitating the adjustment of color values under different light sources to maintain color constancy. This class supports common adaptation transforms based on the von Kries coefficient law, which assumes independent scaling of the cone responses in the human eye. These matrices can be applied to convert color coordinates between different illuminants, ensuring consistent color appearance across various lighting conditions.

Remarks

Supported adaptation matrices include the Bradford, von Kries, and Sharp transforms. These matrices are typically used in conjunction with color space conversions, such as from XYZ to RGB, to achieve accurate color rendition in digital imaging applications.
