Метод	Описание
Angle ( System.Windows v1, System.Windows v2 ) : float	Angle between two vectors in radians.
BetweenX ( Point p, Point p1, Point p2 ) : bool	Returns true iff p lies somewhere between p1 and p2 on x-coordinate
Center ( this rect ) : Point
ClosestPointToLine ( PointF a, PointF b, PointF p ) : PointF
CrossProduct ( System.Windows v1, System.Windows v2 ) : float	Returns the scalar value of the cross product of two vectors.
Distance ( Point p1, Point p2 ) : double	Returns distance between p1 and p2.
Distance ( PointF p1, PointF p2 ) : double	Returns distance between p1 and p2.
Distance2 ( double x1, double y1, double x2, double y2 ) : double
Distance2 ( Point p1, Point p2 ) : float	Squared Euclidean distance of two 2D points.
Distance2 ( PointF p1, PointF p2 ) : float	Squared Euclidean distance of two 2D points.
DotProduct ( System.Windows v1, System.Windows v2 ) : float
EllipseAxes ( MCvBox2D ellipse ) : System.Drawing.PointF[]	Returns the end points of the major and minor axes of an ellipse.
Extend ( PointF p1, PointF p2, float extension ) : PointF	Extends segment (p1, p2) by certain length. The direction of extension is from p1 to p2. If extension is negative, it is equivalent to shortening the segment. The length of the segment cannot be zero.
GradientInDegree ( Point p1, Point p2 ) : float	Returns the angle in degree of the gradient of the line defined by two points.
IsAngleClockwise ( PointF a, PointF b, PointF c ) : bool	Returns true if the angle from vector bc to vector ba is clockwise.
IsAngleClockwise ( System.Windows v1, System.Windows v2 ) : bool
LineIntersection ( PointF a, PointF b, PointF c, PointF d ) : PointF	Point of intersection between line ab and line cd.
LinePointDistance ( PointF p1, PointF p2, PointF p ) : float	Calculates the signed perpendicular distance from a point to a line. Point on the right side of the vector (P1 -> P2) will be NEGATIVE.
LineSegPointDistance ( Point a, Point b, Point p ) : double	Line segement (a, b) to point p distance.
Midpoint ( DepthImagePoint p1, DepthImagePoint p2 ) : DepthImagePoint
Midpoint ( Point p1, Point p2 ) : Point
Midpoint ( PointF p1, PointF p2 ) : PointF
Offset ( Point p1, System.Windows dir, float len ) : Point	Offsets a point in a particular direction by certian length.
Offset ( PointF p1, System.Windows dir, float len ) : PointF
Perp ( System.Windows v ) : System.Windows.Vector	Returns a new vector which is perpendicular to v.
ProjectionDistance ( PointF a, PointF b, PointF p ) : float	Signed length of projection of (a->p) to vector (a->b).
Rotate ( PointF p, PointF pivot, double theta ) : PointF
SegmentsIntersect ( Point a1, Point a2, Point b1, Point b2 ) : bool	Returns true if segment (a1, a2) intersects with segment (b1, b2) including end points.
SegmentsIntersect ( PointF a1, PointF a2, PointF b1, PointF b2 ) : bool
Sign ( double n ) : int
Slope ( Point p1, Point p2 ) : double
Vector ( PointF a, PointF b ) : System.Windows.Vector	Returns a new Vector from a to b.
