pts = cv.RotatedRect.points(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.

Output

• pts 4-by-2 points matrix of the rectangle vertices [x1 y1; x2 y2; x3 y3; x4 y4]. The order is bottom-left, top-left, top-right, bottom-right.
