Enum luminance::blending::Factor

pub enum Factor {
    One,
    Zero,
    SrcColor,
    SrcColorComplement,
    DestColor,
    DestColorComplement,
    SrcAlpha,
    SrcAlphaComplement,

}

Blending factors. Pixel data are multiplied by these factors to achieve several effects driven by blending equations.

Variants

One

1 * color = factor

Zero

0 * color = 0

SrcColor

src * color

SrcColorComplement

(1 - src) * color

DestColor

dst * color

DestColorComplement

(1 - dst) * color

SrcAlpha

srcA * color

SrcAlphaComplement

(1 - src) * color

DstAlpha

dstA * color

DstAlphaComplement

(1 - dstA) * color

SrcAlphaSaturate

This behavior is still not well understood. Dammit.

Trait Implementations

impl Eq for Factor

impl Clone for Factor

fn clone(&self) -> Factor
