Function opencv::imgproc::polylines

pub fn polylines(
    img: &mut dyn ToInputOutputArray, 
    pts: &dyn ToInputArray, 
    is_closed: bool, 
    color: Scalar, 
    thickness: i32, 
    line_type: i32, 
    shift: i32
) -> Result<()>

Draws several polygonal curves.

Parameters

• img: Image.
• pts: Array of polygonal curves.
• isClosed: Flag indicating whether the drawn polylines are closed or not. If they are closed, the function draws a line from the last vertex of each curve to its first vertex.
• color: Polyline color.
• thickness: Thickness of the polyline edges.
• lineType: Type of the line segments. See #LineTypes
• shift: Number of fractional bits in the vertex coordinates.

The function cv::polylines draws one or more polygonal curves.

C++ default parameters

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