Enum ColourMatrix 

pub enum ColourMatrix {
    BeforeCurve([[f32; 4]; 3]),
    AfterCurve([[f32; 4]; 3]),
}

Three rows applied to (R, G, B, 1), with negative results clamped to zero. Placement matters: a tone curve is nonlinear, so a colour transform of HDR before the curve is a different operation from a transform after it.

Variants

BeforeCurve([[f32; 4]; 3])

Transform exposed HDR before forming the tone-table coordinates.

AfterCurve([[f32; 4]; 3])

Transform the tone-table result, before vignette and lookup.

Implementations

impl ColourMatrix

pub fn rows(&self) -> &[[f32; 4]; 3]
