+ <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>

+<br>
+
+ <p class="Body"> Firstly, this field/property is only relevant when JoinType = jtRound and/or EndType = etRound.<br><br> Since flattened paths can never perfectly represent arcs, this field/property specifies a maximum acceptable imprecision ('tolerance') when arcs are approximated in an offsetting operation. Smaller values will increase 'smoothness' up to a point though at a cost of performance and in creating more vertices to construct the arc.<br><br> The default ArcTolerance is 0.25 units. This means that the maximum distance the flattened path will deviate from the 'true' arc will be no more than 0.25 units (before rounding).<br><br> <span class="maroon">Reducing tolerances below 0.25 will <b>not</b> improve smoothness since vertex coordinates will still be rounded to integer values.</span> The only way to achieve sub-integer precision is through coordinate scaling before and after offsetting (see example below).<br><br> <span class="maroon">It's important to make ArcTolerance a sensible fraction of the offset delta (arc radius)</span>. Large tolerances relative to the offset delta will produce poor arc approximations but, just as importantly, very small tolerances will substantially slow offsetting performance while providing unnecessary degrees of precision. This is most likely to be an issue when offsetting polygons whose coordinates have been scaled to preserve floating point precision.<br><br> <b>Example:</b> Imagine a set of polygons (defined in floating point coordinates) that is to be offset by 10 units using <em>round</em> joins, and the solution is to retain floating point precision up to at least 6 decimal places.<br> To preserve this degree of floating point precision, and given that Clipper and ClipperOffset both operate on integer coordinates, the polygon coordinates will be scaled up by 10<sup>8
+ </sup> (and rounded to integers) prior to offsetting. Both offset delta and ArcTolerance will also need to be scaled by this same factor. <em>If ArcTolerance was left unscaled at the default 0.25 units, every arc in the solution would contain a fraction of 44 THOUSAND vertices</em> while the final arc imprecision would be 0.25 × 10<sup>-8
+ </sup> units (ie once scaling was reversed). However, if 0.1 units was an acceptable imprecision in the final <em>unscaled</em> solution, then ArcTolerance should be set to 0.1 × scaling_factor (0.1 × 10<sup>8
+ </sup>). Now if scaling is applied equally to both ArcTolerance and to Delta Offset, then in this example the number of vertices (steps) defining each arc would be a fraction of 23.<br><br> The <a href="../../../../../../offset_triginometry2.svg">formula</a> for the number of steps in a full circular arc is ... Pi / acos(1 - arc_tolerance / abs(delta)) </p>

+ <p class="Body"> <b>PolyTree</b> is intended as a <b>read-only</b> data structure that should only be used to receive <em>solutions</em> from clipping and offsetting operations. It's an alternative to the <a href="../../Types/Paths.htm">Paths</a> data structure which also receives these solutions. PolyTree's two major advantages over the <em>Paths</em> structure are: it properly represents the <b>parent-child relationships</b> of the returned polygons; it differentiates between <b>open</b> and <b>closed</b> paths. However, since PolyTree is a more complex structure than the <em>Paths</em> structure, and since it's more computationally expensive to process (the Execute method being roughly 5-10% slower), <span class="maroon">it should used only be when parent-child polygon relationships are needed, or when open paths are being 'clipped'.</span><br><br> An empty PolyTree object can be passed as the <em>solution</em> parameter in <a href="../Clipper/Methods/Execute.htm"><b>Clipper.Execute</b></a> and in <a href="../ClipperOffset/Methods/Execute.htm"><b>ClipperOffset.Execute</b></a>. Once the clipping or offseting operation is completed, the method returns with the PolyTree structure filled with data representing the solution.<br><br> A <b>PolyTree</b> object is a container for any number of <a href="../PolyNode/_Body.htm"><b>PolyNode</b></a> children, with each contained PolyNode representing a single polygon contour (either an <a href="../../../../Overview/_Body.htm#terminology">outer</a> or <a href="../../../../Overview/_Body.htm#terminology">hole</a> polygon). <span class="maroon">PolyTree itself is a specialized PolyNode whose immediate children represent the top-level <em>outer</em> polygons of the solution. (Its own <a href="../PolyNode/Properties/Contour.htm">Contour</a> property is always empty.)</span> The contained top-level PolyNodes may contain their own PolyNode children representing hole polygons that may also contain children representing nested outer polygons etc. Children of <em>outers</em> will always be <em>holes</em>, and children of <em>holes</em> will always be <em>outers</em>.<br><br> <b>PolyTrees</b> can also contain <b>open</b> paths. Open paths will always be represented by <em>top level</em> PolyNodes. Two functions are provided to quickly separate out <em>open</em> and <em>closed</em> paths from a polytree - <a href="../../Functions/OpenPathsFromPolyTree.htm"><b>OpenPathsFromPolyTree</b></a> and <a href="../../Functions/ClosedPathsFromPolyTree.htm"><b>ClosedPathsFromPolyTree</b></a>. <br><br> <div align="left">
