Expand description

Premultiplied alpha wrapper.

Premultiplied, or alpha masked, or associated alpha colors have had their component values multiplied with their alpha value. They are commonly used in composition algorithms and as output from computer generated graphics. It may also be preferred when interpolating between colors and in other image manipulation operations, such as blurring or resizing images.

use palette::{LinSrgb, LinSrgba};
use palette::blend::{Blend, PreAlpha};

let a = PreAlpha::from(LinSrgba::new(0.4, 0.5, 0.5, 0.3));
let b = PreAlpha::from(LinSrgba::new(0.3, 0.8, 0.4, 0.4));
let c = PreAlpha::from(LinSrgba::new(0.7, 0.1, 0.8, 0.8));

let res: LinSrgba = a.screen(b).overlay(c).into();

Note that converting to and from premultiplied alpha will cause the alpha component to be clamped to [0.0, 1.0], and fully transparent colors will become black.

Fields§

§color: C

The premultiplied color components (original.color * original.alpha).

§alpha: <C as Premultiply>::Scalar

The transparency component. 0.0 is fully transparent and 1.0 is fully opaque.
