I got some old photos to my hand. Unfortunately, I didn't have a possibility to make a direct scan of them and I could make a quick photo of them with my mobile phone.
Their quality is acceptable, but the image is distorted (= photo in the image is not rectangular). Is there any way to fix the distortion with Gimp?
I know there is a Perspective-tool but it does not do what I need. I would expect that I make a (non-rectangular) selection of image area and click "This should be rectangle".
