Set image from bitmap

Image image = new Image ();
Bitmap bitmap = Bitmap.CreateBitmap (200, 100, Bitmap.Config.Argb8888);
Canvas canvas = new Canvas(bitmap);

var paint = new Paint();
paint.Color = Android.Graphics.Color.Red;
paint.SetStyle(Paint.Style.Fill);

Rect rect = new Rect(0, 0, 200, 100);
canvas.DrawRect(rect, paint);

Android.Widget.ImageView contains method SetImageBitmap.
What the best way to set Xamarin.Forms.Image from my bitmap?
