How a shader draw is composited with the destination.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Normal

Standard source-over compositing (premultiplied alpha).

Add

Adds source and destination.

Multiply

Multiplies source and destination.

Screen

Inverts the product of inverted source and destination.

Subtract

Subtracts the source from the destination.

Overlay

Combines Multiply and Screen using the destination as the mask.

Darken

Keeps the darker of source and destination.

Lighten

Keeps the lighter of source and destination.

ColorDodge

Brightens the destination to reflect the source.

ColorBurn

Darkens the destination to reflect the source.

HardLight

Combines Multiply and Screen using the source as the mask.

SoftLight

Softens the contrast between source and destination.

Difference

Absolute difference between source and destination.

Exclusion

Inverted difference with lower contrast.

Hue

Takes hue from the source and saturation/lightness from the destination.

Saturation

Takes saturation from the source and hue/lightness from the destination.

Color

Takes hue and saturation from the source and lightness from the destination.

Luminosity

Takes lightness from the source and hue/saturation from the destination.

AlphaMask

Selects the source where the destination is opaque.
