@Namespace(value="cv")
 @NoOffset
public static class opencv_core.RotatedRect
extends org.bytedeco.javacpp.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(org.bytedeco.javacpp.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
                   opencv_core.Point2f center,
                   @Const @ByRef
                   opencv_core.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
                   opencv_core.Point2f point1,
                   @Const @ByRef
                   opencv_core.Point2f point2,
                   @Const @ByRef
                   opencv_core.Point2f point3)

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

Method Detail

position

public opencv_core.RotatedRect position(long position)

Overrides:

position in class org.bytedeco.javacpp.FloatPointer

points

public void points(opencv_core.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 opencv_core.Rect boundingRect()

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

boundingRect2f

@ByVal
public opencv_core.Rect2f boundingRect2f()

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

center

@ByRef
public opencv_core.Point2f center()

returns the rectangle mass center

center

public opencv_core.RotatedRect center(opencv_core.Point2f center)

size

@ByRef
public opencv_core.Size2f size()

returns width and height of the rectangle

size

public opencv_core.RotatedRect size(opencv_core.Size2f size)

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 opencv_core.RotatedRect angle(float angle)
