Any possible to support self-adaption proportional width or height ?

In some case, need resize image to fixed width with proportional height, or fixed height with proportional width.

@ycrao this seems a useful feature and possible thing to add btw just to be clear, as an example if the image width,height (1000, 500) and the fixed width is 250 the proportional height should be 500
