How can I get pure cropRect without image like ToCropViewController

[kobunketsu]

Hi, thank you for writing such a good framework, implementing a system photo crop editor becomes so easy with it now. But I have some problem while using it. It is hard to get a pure cropRect which size is relative to the original image's size. I don't really need the cropped image rendered, only the size matters, but I have no idea how to retrieve it through the method:

public func cropped(withCropperState cropperState: CropperState) -> UIImage?

Can you give me some hint how to do it?

You can get all the information you need through the CropperViewControllerDelegate's cropperDidConfirm(_:state:).
But you need to calculate it yourself through CropperState
