You can programmatically scroll the BitmapViewer using HScrollPos and VScrollPos properties. So you should just analyze the selection dimensions (SelectionWidth and SelectionHeight) to calculate zoom ratio and the selection position (SelectionLeft and SelectionTop) to calculate where to scroll. Hope this helps.
