public class RotatedRect
extends FloatPointer

\brief 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: \snippet snippets/core_various.cpp RotatedRect_demo

Constructor Detail

RotatedRect

public RotatedRect(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

RotatedRect

public RotatedRect(long size)

Native array allocator. Access with Pointer.position(long).

RotatedRect

public RotatedRect()

default constructor

RotatedRect

public RotatedRect(@Const @ByRef
                   Point2f center,
                   @Const @ByRef
                   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

public RotatedRect(@Const @ByRef
                   Point2f point1,
                   @Const @ByRef
                   Point2f point2,
                   @Const @ByRef
                   Point2f point3)

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

Method Detail

position

public RotatedRect position(long position)

Overrides:

position in class FloatPointer

points

public void points(Point2f pts)

returns 4 vertices of the rectangle

Parameters:

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

boundingRect

@ByVal
public Rect boundingRect()

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

boundingRect2f

@ByVal
public Rect2f boundingRect2f()

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

center

@ByRef
public Point2f center()

returns the rectangle mass center

center

public RotatedRect center(Point2f setter)

size

@ByRef
public Size2f size()

returns width and height of the rectangle

size

public RotatedRect size(Size2f setter)

angle

public float angle()

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

angle

public RotatedRect angle(float setter)
