    Functions

    func Border

    func Border(r image.Rectangle, inset int) [4]image.Rectangle

      Border returns four rectangles that together contain those points between r and r.Inset(inset). Visually:

      00000000
      00000000
      11....22
      11....22
      11....22
      33333333
      33333333
      

      The inset may be negative, in which case the points will be outside r.

      Some of the returned rectangles may be empty. None of the returned rectangles will overlap.
