Eg, if an image had a 20 pixel row of white at the top, and this method was invoked with Color.White then the image returned would have that 20 pixel row removed.

Returns a new image that is scaled to fit the specified bounds while retaining the same aspect ratio as the original image.
Returns a new image that is scaled to fit the specified bounds while retaining the same aspect ratio as the original image.
