Class PremultiplyEffect

Namespace

PaintDotNet.Direct2D1.Effects

Assembly

PaintDotNet.Windows.Core.dll

Use this effect to convert an image from unpremultiplied alpha to premultiplied alpha.

The effect replaces each input pixel P = { R, G, B, A } with P' = { R * A, G * A, B * A, A } in the output.
