struct Rect

Rect structure

x,y coordinates together with width and height that define a rectangle. Can be either normalized [0,1] or absolute representation.

Public Functions

Rect() = default

inline Rect(float x, float y, float width, float height)

inline Rect(float x, float y, float width, float height, bool normalized)

inline Rect(const Rect &r)

inline Rect(const Point2f &org, const Size2f &sz)

inline Rect(const Point2f &org, const Size2f &sz, bool normalized)

inline Rect(const Point2f &pt1, const Point2f &pt2)

inline Rect(const Point2f &pt1, const Point2f &pt2, bool normalized)

Rect &operator=(const Rect &r) = default

Rect &operator=(Rect &&r) = default

inline Point2f topLeft() const

The top-left corner.

inline Point2f bottomRight() const

The bottom-right corner

inline Size2f size() const

Size (width, height) of the rectangle

inline float area() const

Area (width*height) of the rectangle

inline bool empty() const

True if rectangle is empty.

inline bool contains(const Point2f &pt) const

Checks whether the rectangle contains the point.

inline bool isNormalized() const

Whether rectangle is normalized (coordinates in [0,1] range) or not.

inline Rect denormalize(int destWidth, int destHeight) const

Denormalize rectangle.

Parameters:

• destWidth – Destination frame width.

• destHeight – Destination frame height.

inline Rect normalize(int srcWidth, int srcHeight) const

Normalize rectangle.

Parameters:

• srcWidth – Source frame width.

• srcHeight – Source frame height.
