rect = cv.RotatedRect.boundingRect2f(rrect)

Input

• rrect rotated rectangle. A structure with the following fields:
  • center The rectangle mass center [x,y].
  • size Width and height of the rectangle [w,h].
  • angle The rotation angle in a clockwise direction. When the angle is 0, 90, 180, 270 etc., the rectangle becomes an up-right rectangle.
