I am trying to get the intersection of 2 rectangles. What happens if the 2 rectangles do not intersect at all ? Will it give me an error ? Because the output below is what I am getting. The limits are (0,0,1242,375)

[1170 x 232 from (72, 0)]
[1242 x 375 from (0, 0)]
[1242 x 375 from (0, 0)]
[967 x 211 from (275, 0)]
[1242 x 375 from (0, 0)]
[1242 x 375 from (0, 0)]
[1242 x 375 from (0, 0)]
[2147449647 x 375 from (2147483647, 0)]
[1242 x 375 from (0, 0)]

The limits are (0,0,1242,375)(0,0,1242,375). I don't know the rectangles I am passing in. I just want to keep those that intersect and to retain the intersection.
