Possible to crop "inside" cropWidth/cropHeight?

[isaachinman]

Hello! Thanks for a cool component here.

I wasn't exactly sure how to phrase the title of this issue. I am wondering if "Instagram-style" cropping, where one dimension of the photo (either width or height) is actually inside the crop bounds, giving a white-border effect, is possible with this component.

I've installed this component into my project and it seems as though this functionality is not possible out of the box.
