hpe: Hunt-Pointer-Estevez

hpe defines conversions between XYZ (and sRGB) and LMS (long, medium short) cone responses, according to the older HPE algorithms. This is updated in the CAM02 model.

Functions

func SRGBLinToLMS 

func SRGBLinToLMS(rl, gl, bl float32) (l, m, s float32)

SRGBLinToLMS converts sRGB linear to Long, Medium, Short cone-based responses, using the Hunt-Pointer-Estevez transform. This is closer to the actual response functions of the L,M,S cones apparently.

func SRGBToLMS 

func SRGBToLMS(r, g, b float32) (l, m, s float32)

SRGBToLMS converts sRGB to Long, Medium, Short cone-based responses, using the Hunt-Pointer-Estevez transform. This is closer to the actual response functions of the L,M,S cones apparently.

func XYZToLMS 

func XYZToLMS(x, y, z float32) (l, m, s float32)

XYZToLMS convert XYZ to Long, Medium, Short cone-based responses, using the Hunt-Pointer-Estevez transform. This is closer to the actual response functions of the L,M,S cones apparently.
