        var width : int := Pic.Width (pic)
        var height : int := Pic.Height (pic)
        var x, y : int := 0
        loop
            exit when y > maxy
            loop
                exit when x > maxx
                Pic.Draw (pic, x, y, picCopy)
                x := x + width
            end loop
            x := 0
            y := y + height
        end loop
