Function opencv::imgproc::rectangle

pub fn rectangle(
    img: &mut Mat, 
    rec: Rect, 
    color: Scalar, 
    thickness: i32, 
    line_type: i32, 
    shift: i32
) -> Result<()>

Draws a simple, thick, or filled up-right rectangle.

The function cv::rectangle draws a rectangle outline or a filled rectangle whose two opposite corners are pt1 and pt2.

Parameters

• img: Image.
• pt1: Vertex of the rectangle.
• pt2: Vertex of the rectangle opposite to pt1 .
• color: Rectangle color or brightness (grayscale image).
• thickness: Thickness of lines that make up the rectangle. Negative values, like #FILLED, mean that the function has to draw a filled rectangle.
• lineType: Type of the line. See #LineTypes
• shift: Number of fractional bits in the point coordinates.

Overloaded parameters

use rec parameter as alternative specification of the drawn rectangle: r.tl() and r.br()-Point(1,1) are opposite corners

C++ default parameters

• thickness: 1
• line_type: LINE_8
• shift: 0
