I have two images. One is the original (let's say it's 830 x 1222 pixels. The other is a cropped image (let's say 300 x 300 pixels) takend from the original. Cropped image is as per the ratio of the Green rectangle shown in to the sample image below.
What I'm looking for is a way using objective C (iOS) to look at both images and find the coordinates of the cropped image within the original.
Hope that makes sense? Any help appreciated.
