<p>If <var>swept_object</var> is a point list and there is no closure tag,

<a name="index-closure-tag_002c-_003c_003e-3"></a>
then <code>sweep</code> connects <em><var>n</var>+1</em> successive copies of each
point (including the original) with straight line segments to form a
polyline. If there are <em>m</em> points in the original point list,
<a name="index-point-list"></a>
then <em>m</em> polylines with <var>n</var> segments each are formed by the
sweep. In this manner, <code>sweep</code> forms a set of one-dimensional
objects (polylines) from zero-dimensional ones (points).

<p>When there <em>is</em> a closure tag,

<code>sweep</code> connects <var>n</var>
successive copies of each point (including the original) with straight
line segments and finally connects the last copy back to the original
to form a polygon with <var>n</var> sides. If there are <em>m</em> points in
the original point list, then <em>m</em> polygons with <var>n</var> sides
each are formed by the sweep. In this manner, <code>sweep</code> forms a
set of two-dimensional objects (polygons) from zero-dimensional ones
(points).

<p>Options

of the <code>sweep</code> are copied directly to the resulting
polyline(s).
