This is an example of resizing the enabled image
When the enabled element's width or height changes, you must call resize() so cornerstone can update
the canvas width and height. The image is automatically rescaled. When the image fitted the window
before the resize then it will also fit after the resize. If the image was zoomed or panned before
the resize then the image will be rescaled accordingly. Try this out here by dragging the red square
in the right corner of the image.
