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: RotatedRect_demo

Implementations

impl RotatedRect

pub fn default() -> Result<RotatedRect>

default constructor

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

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>

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

Trait Implementations

impl Boxed for RotatedRect

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

fn as_raw_mut(&mut self) -> *mut c_void

Return the underlying mutable raw pointer

impl Debug for RotatedRect

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for RotatedRect

fn drop(&mut self)

Executes the destructor for this type.

impl RotatedRectTrait for RotatedRect

fn as_raw_mut_RotatedRect(&mut self) -> *mut c_void

fn set_center(&mut self, val: Point2f)

returns the rectangle mass center

fn set_size(&mut self, val: Size2f)

returns width and height of the rectangle

fn set_angle(&mut self, val: f32)

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

impl RotatedRectTraitConst for RotatedRect

fn as_raw_RotatedRect(&self) -> *const c_void

fn center(&self) -> Point2f

returns the rectangle mass center

fn size(&self) -> Size2f

returns width and height of the rectangle

fn angle(&self) -> f32

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

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

returns 4 vertices of the rectangle

fn bounding_rect(&self) -> Result<Rect>

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

fn bounding_rect2f(&self) -> Result<Rect_<f32>>

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