Trait dssim::GammaPixel

pub trait GammaPixel {
    type Component: GammaComponent;
    type Output;
    fn to_linear(&self, gamma_lut: &[f32]) -> Self::Output;

    fn make_lut() -> Vec<f32> { ... }
}

Downsampling should be done in linear RGB color space.

Used by ToRGBAPLU

This trait provides gamma to linear conversion via lookup table, and there's implementation for sRGB for common RGB types.

Associated Types
