How to create a document from an existing picture

[Caipirinia 8]

I know how to create a document note using the camera of a smartphone. However, is there a way to create a document note from an already taken photo. I have a photo of a receipt and I want it cropped and sharpened in the usual way as when you take a document photo via the iOS app. Is this possible either in web or in iOS? The only thing I was able to do is to attach a photo to a note, but without the cropping and image fine tuning. Thank you in advance.

Hi.  AFAIK there's no current option to apply any 'fixes' to an existing image - your only possibility would be to take a live document photo of the image onscreen.
