Function opencv::imgproc::line

pub fn line(
    img: &mut dyn ToInputOutputArray, 
    pt1: Point, 
    pt2: Point, 
    color: Scalar, 
    thickness: i32, 
    line_type: i32, 
    shift: i32
) -> Result<()>

Draws a line segment connecting two points.

The function line draws the line segment between pt1 and pt2 points in the image. The line is clipped by the image boundaries. For non-antialiased lines with integer coordinates, the 8-connected or 4-connected Bresenham algorithm is used. Thick lines are drawn with rounding endings. Antialiased lines are drawn using Gaussian filtering.

Parameters

• img: Image.
• pt1: First point of the line segment.
• pt2: Second point of the line segment.
• color: Line color.
• thickness: Line thickness.
• lineType: Type of the line. See #LineTypes.
• shift: Number of fractional bits in the point coordinates.

C++ default parameters

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