Cropping an UIImage

Question

I\'ve got some code that resizes an image so I can get a scaled chunk of the center of the image - I use this to take a UIImage and return a small, square repre

Answer 1

Looks a little bit strange but works great and takes into consideration image orientation:

var image:UIImage = ...

let img = CIImage(image: image)!.imageByCroppingToRect(rect)
image = UIImage(CIImage: img, scale: 1, orientation: image.imageOrientation)
