.. ocv:class:: RotatedRect
Template class for rotated rectangles specified by the center, size, and the rotation angle in degrees.
The class represents rotated (i.e. not up-right) rectangles on a plane. Each rectangle is specified by the center point (mass center), length of each side (represented by cv::Size2f structure) and the rotation angle in degrees.
.. ocv:function:: RotatedRect::RotatedRect()
.. ocv:function:: RotatedRect::RotatedRect(const Point2f& center, const Size2f& size, float angle)
.. ocv:function:: RotatedRect::RotatedRect(const CvBox2D& box)
:param center: The rectangle mass center.
:param size: Width and height of the rectangle.
:param angle: The rotation angle in a clockwise direction. When the angle is 0, 90, 180, 270 etc., the rectangle becomes an up-right rectangle.
:param box: The rotated rectangle parameters as the obsolete CvBox2D structure.
.. ocv:function:: void RotatedRect::points(Point2f* pts) const
.. ocv:function:: Rect RotatedRect::boundingRect() const
.. ocv:function:: RotatedRect::operator CvBox2D() const
:param pts: The points array for storing rectangle vertices.
The sample below demonstrates how to use RotatedRect:
::
Mat image(200, 200, CV_8UC3, Scalar(0));
RotatedRect rRect = RotatedRect(Point2f(100,100), Size2f(100,50), 30);
Point2f vertices[4];
rRect.points(vertices);
for (int i = 0; i < 4; i++)
line(image, vertices[i], vertices[(i+1)%4], Scalar(0,255,0));
Rect brect = rRect.boundingRect();
rectangle(image, brect, Scalar(255,0,0));
imshow("rectangles", image);
waitKey(0);
