<p class="Body"> When adding paths to a <a href="../Classes/ClipperOffset/_Body.htm">ClipperOffset</a> object via the <a href="../Classes/ClipperOffset/Methods/AddPaths.htm">AddPaths</a> method, the joinType parameter may be one of three types - jtMiter, jtSquare or jtRound.<br><br> <img src="../../../../Images/jointypes.png" alt="" border="0"><br><br>
<ul>
<li>jtMiter: There's a necessary limit to mitered joins since offsetting edges that join at very acute angles will produce excessively long and narrow 'spikes'. To contain these potential spikes, the ClippOffset object's <a href="../Classes/ClipperOffset/Properties/MiterLimit.htm"><b>MiterLimit</b></a> property specifies a maximum distance that vertices will be offset <em>(in multiples of delta)</em>. For any given edge join, when miter offsetting would exceed that maximum distance, 'square' joining is applied.<br></li>
<li>jtRound: While flattened paths can never perfectly trace an arc, they are approximated by a series of arc chords (see ClipperObject's <a href="../Classes/ClipperOffset/Properties/ArcTolerance.htm"><b>ArcTolerance</b></a> property).<br></li>
<li>jtSquare: Squaring is applied uniformally at all convex edge joins at 1 × delta.</li>
