Scale an image to fit using C#, Xamarin and SpriteKit

ScaleToFit.cs

var image = SKSpriteNode.FromTexture(SKTexture.FromImageNamed("image-name"));
image.Position = new CGPoint(Frame.GetMidX(), Frame.GetMidY());

var widthScaleFactor = device.DeviceSize.Width / image.Size.Width;
var heightScaleFactor = device.DeviceSize.Height / image.Size.Height;
var scaleFactor = widthScaleFactor < heightScaleFactor ? widthScaleFactor : heightScaleFactor;

image.SetScale(scaleFactor);
