#### 8.1.12 Line (polyline)

• Line( <list>, <closed> [, radius] ) or Ligne( <list>, <closed> [, radius] ).
• Description: draw the polyline defined by the list. If the parameter <closed> is 1, the polyline will be closed, if the value is 0, the line is open. If the argument <rayon> is set (0 by default), then the polyline “angles” are rounded with a circle arc whose radius is <radius>.
