Zoom able image control
Image control with zoom in and out by double tap or Slider's value in desktop and pinch zoom in touch enabled screen.
On pc, user has to press Ctrl + wheel to zoom, the author means just using wheel.

You should be able to add the Image to the ScrollViewer to accomplish this
