Struct cv::core::Rect

#[repr(C)]pub struct Rect {
    pub x: c_int,
    pub y: c_int,
    pub width: c_int,
    pub height: c_int,
}

The Rect defines a rectangle in integer.

Fields

x: c_int

x coordinate of the left-top corner

y: c_int

y coordinate of the left-top corner

width: c_int

width of this rectangle

height: c_int

height of this rectangle

Implementations

impl Rect

pub fn new(x: c_int, y: c_int, width: c_int, height: c_int) -> Self

Creates a new Rect with (x, y, width, height) parameters.

pub fn scale(&self, ratio: f32) -> Rect

Scales the rectangle by the specified ratio.

pub fn normalize_to_mat(&self, mat: &Mat) -> Rect2f

Normalize the rectangle according to the image (if the rectangle is inside the image, then the result should be all within (0, 1).
