Options</p>
<ul>
<li>:x and :y – as center of the circle.</li>
<li>:radius – as radius(in points).</li>
<li>:ang1 – the angle of a vector from (:x , :y ) of length :radius to the first endpoint of the circle.</li>
<li>:ang2 – the angle of a vector from (:x, :y) of length :radius to the second endpoint of the circle.</li>
<li>:content – facade to ShapeConent with same parameters.</li>
<li>:border – facade to Border with same parameters.</li>
<li>:use – :arc draws counterclockwise and :arcn (arc negative) clockwise direction.</li>
</ul>
