[−][src]Struct opencv::core::RotatedRect

pub struct RotatedRect { /* fields omitted */ }

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 image

Methods

impl RotatedRect[src]

pub fn as_raw_RotatedRect(&self) -> *mut c_void[src]

pub unsafe fn from_raw_ptr(ptr: *mut c_void) -> Self[src]

impl RotatedRect[src]

pub fn center(&self) -> Result<Point2f>[src]

returns the rectangle mass center

pub fn set_center(&mut self, val: Point2f) -> Result<()>[src]

returns the rectangle mass center

pub fn size(&self) -> Result<Size2f>[src]

returns width and height of the rectangle

pub fn set_size(&mut self, val: Size2f) -> Result<()>[src]

returns width and height of the rectangle

pub fn angle(&self) -> Result<f32>[src]

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

pub fn set_angle(&mut self, val: f32) -> Result<()>[src]

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

pub fn default() -> Result<RotatedRect>[src]

default constructor

pub fn new(center: Point2f, size: Size2f, angle: f32) -> Result<RotatedRect>[src]

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.

pub fn for_points(
    point1: Point2f,
    point2: Point2f,
    point3: Point2f
) -> Result<RotatedRect>[src]

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

pub fn points(&self, pts: &mut [Point2f]) -> Result<()>[src]

returns 4 vertices of the rectangle

Parameters

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

pub fn bounding_rect(&self) -> Result<Rect>[src]

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

pub fn bounding_rect2f(&self) -> Result<Rect2f>[src]

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