+ <p class="Body"> Once <em>subject</em> and <em>clip</em> paths have been assigned (via <a href="../../ClipperBase/Methods/AddPath.htm">AddPath</a> and/or <a href="../../ClipperBase/Methods/AddPaths.htm">AddPaths</a>), <b>Execute</b> can then perform the clipping operation (intersection, union, difference or XOR) specified by the <a href="../../../Types/ClipType.htm">clipType</a> parameter.<br><br> The <b>solution</b> parameter can be either a <a href="../../../Types/Paths.htm">Paths</a> or <a href="../../PolyTree/_Body.htm">PolyTree</a> structure. <span class="maroon">The Paths structure is simpler than the PolyTree stucture.</span> Because of this it is quicker to populate and hence clipping performance is a little better (it's roughly 10% faster). However, the PolyTree data structure provides more information about the returned paths which may be important to users. Firstly, <span class="maroon">the PolyTree structure preserves nested parent-child polygon relationships</span> (ie outer polygons owning/containing <em>holes</em> and holes owning/containing other outer polygons etc). Also, <span class="maroon"><b>only the PolyTree structure can differentiate between open and closed paths</b></span> since each PolyNode has an <a href="../../PolyNode/Properties/IsOpen.htm"><b>IsOpen</b></a> property. (The <a href="../../../Types/Path.htm"><b>Path</b></a> structure has no member indicating whether it's open or closed.) For this reason, <span class="maroon"><b>when <em>open</em> paths are passed to a Clipper object, the user must use a PolyTree object as the solution parameter</b></span>, otherwise an exception will be raised.<br><br> When a PolyTree object is used in a clipping operation on <b>open</b> paths, two ancilliary functions have been provided to quickly separate out <em>open</em> and <em>closed</em> paths from the solution - <a href="../../../Functions/OpenPathsFromPolyTree.htm"><b>OpenPathsFromPolyTree</b></a> and <a href="../../../Functions/ClosedPathsFromPolyTree.htm"><b>ClosedPathsFromPolyTree</b></a>. <a href="../../../Functions/PolyTreeToPaths.htm"><b>PolyTreeToPaths</b></a> is also available to convert path data to a Paths structure (irrespective of whether they're <em>open</em> or <em>closed</em>).<br><br> <img src="../../../../../../Images/common_edges.png" alt="" border="0" align="right"> There are several things to note about the solution paths returned:
+ <ul>
+
+ <li>they aren't in any specific order</li>
+
+ <li>they should never overlap or be self-intersecting (but see notes on <a href="../../../../../Overview/Rounding.htm"><b>rounding</b></a>)</li>
+
+ <li>holes will be oriented opposite outer polygons</li>
+
+ <li>the <strong>solution fill type</strong> can be considered either <em>EvenOdd</em> or <em>NonZero</em> since it will comply with either filling rule</li>
+
+ <li>polygons may rarely share a common edge (though this is now <em>very rare</em> as of version 6)</li>
+
+ </ul> </p><br>
+
+
+ <p class="Body"> The <b>subjFillType</b> and <b>clipFillType</b> parameters define the polygon <a href="../../../Types/PolyFillType.htm"><b>fill rule</b></a> to be applied to the polygons (ie closed paths) in the subject and clip paths respectively. (It's usual though obviously not essential that both sets of polygons use the same fill rule.)<br><br> <b>Execute</b> can be called multiple times without reassigning subject and clip polygons (ie when different clipping operations are required on the same polygon sets).<br><br> </p>
