Detailed Description

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 Size2f structure) and the rotation angle in degrees.

The sample below demonstrates how to use RotatedRect:

Constructor & Destructor Documentation

◆ RotatedRect() [1/3]

CV_WRAP cv::RotatedRect::RotatedRect ( )

default constructor

◆ RotatedRect() [2/3]

CV_WRAP cv::RotatedRect::RotatedRect	(	const Point2f &	center,
		const Size2f &	size,
		float	angle
	)

full constructor

Parameters

center	The rectangle mass center.
size	Width and height of the rectangle.
angle	The rotation angle in a clockwise direction. When the angle is 0, 90, 180, 270 etc., the rectangle becomes an up-right rectangle.

◆ RotatedRect() [3/3]

CV_WRAP cv::RotatedRect::RotatedRect	(	const Point2f &	point1,
		const Point2f &	point2,
		const Point2f &	point3
	)

Any 3 end points of the RotatedRect. They must be given in order (either clockwise or anticlockwise).

Member Function Documentation

◆ boundingRect()

CV_WRAP Rect cv::RotatedRect::boundingRect ( ) const

returns the minimal up-right integer rectangle containing the rotated rectangle

◆ boundingRect2f()

CV_WRAP Rect2f cv::RotatedRect::boundingRect2f ( ) const

returns the minimal (exact) floating point rectangle containing the rotated rectangle, not intended for use with images

◆ points() [1/2]

CV_WRAP void cv::RotatedRect::points ( CV_OUT std::vector< Point2f > & pts ) const

◆ points() [2/2]

void cv::RotatedRect::points ( Point2f pts[] ) const

returns 4 vertices of the rotated rectangle

Parameters

pts	The points array for storing rectangle vertices. The order is bottomLeft, topLeft, topRight, bottomRight.

Note: Bottom, Top, Left and Right sides refer to the original rectangle (angle is 0), so after 180 degree rotation bottomLeft point will be located at the top right corner of the rectangle.

Member Data Documentation

◆ angle

CV_PROP_RW float cv::RotatedRect::angle

returns the rotation angle. When the angle is 0, 90, 180, 270 etc., the rectangle becomes an up-right rectangle.

◆ center

CV_PROP_RW Point2f cv::RotatedRect::center

returns the rectangle mass center

◆ size

CV_PROP_RW Size2f cv::RotatedRect::size

returns width and height of the rectangle
