Event Type
Examples
myView.PaintSurface += (sender, e) => {
var surface = e.Surface;
var surfaceWidth = e.Info.Width;
var surfaceHeight = e.Info.Height;
var canvas = surface.Canvas;
// draw on the canvas
canvas.Flush ();
};
Remarks
There are two ways to draw on this surface: by overriding the OnPaintSurface(SKPaintSurfaceEventArgs) method, or by attaching a handler to the PaintSurface event.
Note
If a version of SkiaSharp prior to version v1.68.x is being used, then the DrawInSurface(SKSurface, SKImageInfo) method should be overridden instead of OnPaintSurface(SKPaintSurfaceEventArgs).
