SKNoDrawCanvas Class

Definition

A type of SKCanvas that provides a base type for canvases that do not need to rasterize.

public class SKNoDrawCanvas : SkiaSharp.SKCanvas

Remarks

These canvases are not backed by any device/pixels and they use conservative clipping (clipping calls only use rectangles).
