      Returns:
      A copy of the shape or shape outline (never null).

      Parameters:
      xPoints - the x-coordinates, read up to index nPoints - 1
      yPoints - the y-coordinates, read up to index nPoints - 1
      nPoints - the number of points to use for the polyline.
      close - true to draw a line back to the first point
