Class BackdropLayerEffect

Namespace

SixLabors.ImageSharp.Drawing.Processing

Assembly

SixLabors.ImageSharp.Drawing.dll

Describes an effect applied to the backdrop of a compositing layer: the pixels already on the canvas beneath the layer's region are filtered when the layer is opened, and the layer's content then renders above the filtered backdrop. This is the CSS backdrop-filter model; the filtered result is clipped to the layer's region.
