I have a block arrow and want to rotate it by an angle theta relative to a point in the middle of the base of the arrow... If you rotate point px py around point ox oy by angle theta you'll get p'x cos theta px ox sin theta py oy ox p'y sin theta.. px py around point ox oy by angle theta you'll get p'x cos theta px ox sin theta py oy ox p'y sin theta px ox cos theta py oy..
