Blend mode used for draw primitives.

This mirrors Jetpack Compose’s blend-mode vocabulary while the renderer currently guarantees SrcOver and DstOut behavior.

Variants

Clear

Clears the destination to transparent where the source draws.

Src

Replaces the destination with the source.

Dst

Keeps the destination and discards the source.

SrcOver

Draws the source over the destination. This is the default.

DstOver

Draws the destination over the source.

SrcIn

Keeps the source only where the destination is opaque.

DstIn

Keeps the destination only where the source is opaque.

SrcOut

Keeps the source only where the destination is transparent.

DstOut

Keeps the destination only where the source is transparent.

SrcAtop

Draws the source over the destination, only where the destination is opaque.

DstAtop

Draws the destination over the source, only where the source is opaque.

Xor

Keeps the source and the destination where the other is transparent.

Plus

Adds the source and destination colors and alphas.

Modulate

Multiplies the source and destination colors and alphas.

Screen

Inverts, multiplies and inverts again, which lightens the result.

Overlay

Multiplies or screens depending on the destination color, which raises contrast.

Darken

Keeps the darker color of each channel.

Lighten

Keeps the lighter color of each channel.

ColorDodge

Brightens the destination by the source color.

ColorBurn

Darkens the destination by the source color.

HardLight

Multiplies or screens depending on the source color.

SoftLight

A softer version of HardLight: darkens or lightens depending on the source color.

Difference

Subtracts the darker color from the lighter one in each channel.

Exclusion

Like Difference with lower contrast.

Multiply

Multiplies the source and destination colors, which darkens the result.

Hue

Takes the hue of the source with the saturation and luminosity of the destination.

Saturation

Takes the saturation of the source with the hue and luminosity of the destination.

Color

Takes the hue and saturation of the source with the luminosity of the destination.

Luminosity

Takes the luminosity of the source with the hue and saturation of the destination.

Implementations

impl BlendMode

pub const ALL: [BlendMode; 29]

Every mode in declaration order, so mode as u32 indexes it.

Trait Implementations
