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
11....22
11....22
11....22

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.
