Golang relative image cropping
import "image"
type SubImager interface {
SubImage(r image.Rectangle) image.Image
}
// RelativeSubImage return cropped image relative to the previous crop
// If you try to make a sub image from another sub image, you may run into
// unusual behavior due to the fact that absolute coordinates are used for each crop,
// instead you can use this function so as not to constantly remember this nuance.
