Struct cv::Rect

#[repr(C)]
pub struct Rect {
    pub x: i32,
    pub y: i32,
    pub width: i32,
    pub height: i32,
}

The Rect defines a rectangle in integer.

Fields

x: i32

x coordinate of the left-top corner

y: i32

y coordinate of the left-top corner

width: i32

width of this rectangle

height: i32

height of this rectangle

Methods

impl Rect

pub fn new(x: i32, y: i32, width: i32, height: i32) -> 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).
