Enum BlendMode 

pub enum BlendMode {
    Normal,
    Multiply,
    Screen,
    Overlay,
    HardLight,
    ColorDodge,
    ColorBurn,
    LinearBurn,
    Exclusion,
}

Blend mode for layer compositing.

Variants

Normal

Standard alpha-compositing (Porter-Duff over).

Multiply

Multiply blend: dst * src per channel.

Screen

Screen blend: 1 - (1 - dst) * (1 - src) per channel.

Overlay

Overlay: multiply for dark areas, screen for light areas.

HardLight

Hard Light: overlay with source and destination roles swapped. Multiply if src < 0.5, screen otherwise.

ColorDodge

Color Dodge: brightens the base colour to reflect the blend colour. dst / (1 - src), clamped to 1.

ColorBurn

Color Burn: darkens the base colour to reflect the blend colour. 1 - (1 - dst) / src, clamped to 0.

LinearBurn

Linear Burn: dst + src - 1, clamped to 0.

Exclusion

Exclusion: dst + src - 2 * dst * src.

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for BlendMode

impl Debug for BlendMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BlendMode

fn default() -> Self

Returns the “default value” for a type.

impl Eq for BlendMode

impl PartialEq for BlendMode

fn eq(&self, other: &BlendMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
