WPF - find actual top and left of an image after rotating it

Question

I am using WPF and I have an image of an 8.5" * 11" piece of paper on a Canvas. I am then rotating the image using a RotateTransform, with the axis being in the middle of the page (that is, RotateTransformOrigin="0.5,0.5"). How can I find the actual location on the canvas of the corners of the image?

(this is the geometry way)

Answer 2

_image.TranslatePoint(new Point(0, 0), _canvas);

Will this do?
