Enum BlendMode 

pub enum BlendMode {
    Normal,
    Multiply,
    Screen,
    Overlay,
    Darken,
    Lighten,
    ColorDodge,
    ColorBurn,
    HardLight,
    SoftLight,
    Difference,
    Exclusion,
    Hue,
    Saturation,
    Color,
    Luminosity,
}

Artistic RGB operation applied before Porter-Duff source-over coverage.

The modes and their formulas are those of W3C Compositing and Blending Level 1, evaluated in the renderer’s BlendSpace. The first twelve are separable (each channel on its own); Hue, Saturation, Color, and Luminosity are not.

Variants

Normal

Preserve the source color.

Multiply

Multiply source and backdrop components.

Screen

Inverse-multiply source and backdrop components.

Overlay

Multiply dark backdrop regions and screen light regions.

Darken

The darker of source and backdrop, per channel.

Lighten

The lighter of source and backdrop, per channel.

ColorDodge

Brighten the backdrop to reflect the source.

ColorBurn

Darken the backdrop to reflect the source.

HardLight

Multiply or screen, depending on the source.

SoftLight

Darken or lighten, depending on the source: a diffused hard light.

Difference

The absolute difference of source and backdrop.

Exclusion

Like difference, with lower contrast.

Hue

The source’s hue with the backdrop’s saturation and luminosity.

Saturation

The source’s saturation with the backdrop’s hue and luminosity.

Color

The source’s hue and saturation with the backdrop’s luminosity.

Luminosity

The source’s luminosity with the backdrop’s hue and saturation.
