Question

Answer 1

Don't think of coordinates as indicating where pixels are. Think of them as being between the pixels. That way, the area of a 2x2 rectangle should be 4, not 9.

bool bOverlap = !((A.Left >= B.Right || B.Left >= A.Right)
               && (A.Bottom >= B.Top || B.Bottom >= A.Top));
