Draws several polygonal curves.
- color_in – Polyline color.
- image_in – Input image.
- isClosed_in – 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.
- lineType_in – Type of the line segments. See the line description.
- pts_in – Array of polygonal curves.
- shift_in – Number of fractional bits in the vertex coordinates.
- thickness_in – Thickness of the polyline edges.
- image_out – Output image.
