Detailed Description

template<typename _Tp> class CV_EXPORTS Point_

// C++ code:


typedef _Tp value_type;

// various constructors


Point_(_Tp _x, _Tp _y);

Point_(const Point_& pt);

Point_(const CvPoint& pt);

Point_(const CvPoint2D32f& pt);

Point_(const Size_<_Tp>& sz);

Point_(const Vec<_Tp, 2>& v);

Point_& operator = (const Point_& pt);

//! conversion to another data type

template<typename _Tp2> operator Point_<_Tp2>() const;

//! conversion to the old-style C structures

operator CvPoint() const;

operator CvPoint2D32f() const;

operator Vec<_Tp, 2>() const;

//! dot product

_Tp dot(const Point_& pt) const;

//! dot product computed in double-precision arithmetics

double ddot(const Point_& pt) const;

//! cross-product

double cross(const Point_& pt) const;

//! checks whether the point is inside the specified rectangle

bool inside(const Rect_<_Tp>& r) const;

_Tp x, y; //< the point coordinates


Template class for 2D points specified by its coordinates

x and y. An instance of the class is interchangeable with C structures, CvPoint and CvPoint2D32f. There is also a cast operator to convert point coordinates to the specified type. The conversion from floating-point coordinates to integer coordinates is done by rounding. Commonly, the conversion uses thisoperation for each of the coordinates. Besides the class members listed in the declaration above, the following operations on points are implemented:

// C++ code:

pt1 = pt2 + pt3;

pt1 = pt2 - pt3;

pt1 = pt2 * a;

pt1 = a * pt2;

pt1 += pt2;

pt1 -= pt2;

pt1 *= a;

double value = norm(pt); // L2 norm

pt1 == pt2;

pt1 != pt2;

For your convenience, the following type aliases are defined:

typedef Point_<int> Point2i;

typedef Point2i Point;

typedef Point_<float> Point2f;

typedef Point_<double> Point2d;


Point2f a(0.3f, 0.f), b(0.f, 0.4f);

Point pt = (a + b)*10.f;

cout << pt.x << ", " << pt.y << endl;
