Crop an image into a rectangle shape when the cropping points are on any shape which has 4 points - IOS/Swift

In my project, I want to set 4 cropping points manually on an image and crop that image according to set points. For example have a look on below image.

enter image description here

Like this, all I want is to crop the image according to that path and after cropping it should be a rectangle. This is just like image cropping in CamScanner IOS application. If anyone have any idea how to do this any help would be highly appreciated.

I think you need geometric_transformations.

If you plan to use opencv, here is a good example: http://www.pyimagesearch.com/2014/08/25/4-point-opencv-getperspective-transform-example/
