+ <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 &times; 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 &times; scaling_factor (0.1 &times; 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">The ClipperOffset class encapsulates the process of offsetting (inflating/deflating) both open and closed paths using a number of different join types and end types.<br><br> <em>(This class replaces the now deprecated OffsetPaths function which was less flexible.)</em><br><br> <b>Preconditions for offsetting:</b><br> 1. The orientations of closed paths must be consistent such that outer polygons share the same orientation, and any holes have the opposite orientation (ie non-zero filling). Open paths must be oriented with closed outer polygons.<br> 2. Polygons must not self-intersect. <br><br> <b>Limitations:</b><br> When offsetting, small artefacts may appear where polygons overlap. To avoid these artefacts, offset overlapping polygons separately.<br><br><br> <img src="../../../../../Images/offset1.png" alt="" width="310" height="314" border="0" align="right">

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">

+ <p class="Body"> <b>cInt</b> is the integer type used by the Clipper Library to represent vertex coordinate values. (See also <a href="./IntPoint.htm">IntPoint</a>.)<br><br> The library uses integers instead of floating point values to preserve <a href="http://www.mpi-inf.mpg.de/~kettner/pub/nonrobust_cgta_06.pdf" target="_blank">numerical robustness</a>. (Very early versions of the library used floating point coordinates, but it became apparent that floating point imprecision was always going to cause occasional errors.)<br><br> By default <b>cInt</b> represents a signed 64bit integer and polygon coordinates can have any value in the range &plusmn; 9.2e+18. This accommodates the scaling of floating point coordinate values to very large integers so that very high degrees of precision can be retained during clipping. However, if coordinate values can be kept within the range &plusmn; 3.0e+9, then by avoiding large integer math, a modest ~10% improvement in clipping performance is achieved.<br><br> If the preprocessor directive <a href="../PreProcessor/Defines.htm"><b>use_int32</b></a> is defined, cInt will represent a signed 32bit integer. This improves clipping performance by 20-30% but the trade-off is that coordinate values are restricted to the much narrower range of &plusmn; 46340. </p>

An <em>integer</em> storage type has been deliberately chosen to preserve <a href="http://www.mpi-inf.mpg.de/~kettner/pub/nonrobust_cgta_06.pdf" target="_blank"><b>numerical robustness</b></a>. (Early versions of the library used floating point coordinates, but it became apparent that floating point imprecision would always cause occasional errors.)<br><br> A sequence of IntPoints are contained within a <a href="./Path.htm">Path</a> structure to represent a single contour.<br><br> As of version 6, IntPoint now has <span class="maroon">an optional third member 'Z'</span>. This can be enabled by exposing (ie uncommenting) the PreProcessor define '<a href="../PreProcessor/Defines.htm"><b>use_xyz</b></a>'. When the Z member is used, its values will be copied to corresponding verticies in solutions to clipping operations. However, at points of intersection where there's no corresponding Z value, the value will be assigned zero unless a new value is provided by a user supplied <a href="../Classes/Clipper/Properties/ZFillFunction.htm"><b>callback function</b></a>.<br><br> Users wishing to clip or offset polygons containing <em>floating point</em> coordinates need to use appropriate scaling when converting these values to and from <em>IntPoints</em>.<br><br> See also the notes on <a href="../../../Overview/Rounding.htm">rounding</a>. </p>

+
+
+ <p class="Body"> <em>Filling</em> indicates those regions that are <em>inside</em> a closed path (ie 'filled' with a brush color or pattern in a graphical display) and those regions that are <em>outside</em>. The Clipper Library supports 4 filling rules: Even-Odd, Non-Zero, Positive and Negative.<br><br> The simplest filling rule is <em>Even-Odd</em> filling (sometimes called <em>alternate</em> filling). Given a group of closed paths start from a point outside the paths and progress along an imaginary line through the paths. When the first path is crossed the encountered region is filled. When the next path is crossed the encountered region is <em>not</em> filled. Likewise, each time a path is crossed, filling starts if it had stopped and stops if it had started.<br><br> With the exception of <em>Even-Odd</em> filling, all other filling rules rely on <b>edge direction</b> and <b>winding numbers</b> to determine filling. Edge direction is determined by the order in which vertices are declared when constructing a path. Edge direction is used to determine the <b>winding number</b> of each polygon subregion.<br><br> <img src="../../../../Images/wn.png" alt="" width="16" height="16" border="0" align="absmiddle"> The winding number for each polygon sub-region can be derived by: <ol>
+
+ <li>starting with a winding number of zero and</li>
+
+ <li>from a point (P1) that's outside all polygons, draw an imaginary line to a point that's inside a given sub-region (P2)</li>
+
+ <li>while traversing the line from P1 to P2, for each path that crosses the imaginary line from right to left increment the winding number, and for each path that crosses the line from left to right decrement the winding number.</li>
+
+ <li>Once you arrive at the given sub-region you have its winding number.</li>
+
+ </ol> </p>
+
+ <p class="Body"> <img src="../../../../Images/winding_number.png" alt="" width="720" height="250" border="0"><br> <b>Even-Odd (Alternate)</b>: Odd numbered sub-regions are filled, while even numbered sub-regions are not.<br> <b>Non-Zero (Winding)</b>: All non-zero sub-regions are filled.<br> <b>Positive</b>: All sub-regions with winding counts &gt; 0 are filled.<br> <b>Negative</b>: All sub-regions with winding counts &lt; 0 are filled.<br><br> Paths are added to a Clipper object using the <a href="../Classes/ClipperBase/Methods/AddPath.htm">AddPath</a> or <a href="../Classes/ClipperBase/Methods/AddPaths.htm">AddPaths</a> methods and the filling rules (for subject and clip polygons separately) are specified in the <a href="../Classes/Clipper/Methods/Execute.htm">Execute</a> method.<br><br> Polygon regions are defined by one or more closed paths which may or may not intersect. A single polygon region can be defined by a single non-intersecting path or by multiple non-intersecting paths where there's typically an 'outer' path and one or more inner 'hole' paths. Looking at the three shapes in the image above, the middle shape consists of two concentric rectangles sharing the same clockwise orientation. With even-odd filling, where orientation can be disregarded, the inner rectangle would create a hole in the outer rectangular polygon. There would be no hole with non-zero filling. In the concentric rectangles on the right, where the inner rectangle is orientated opposite to the outer, a hole will be rendered with either even-odd or non-zero filling. A single path can also define multiple subregions if it self-intersects as in the example of the 5 pointed star shape below.<br><br> <img src="../../../../Images/evenodd.png" alt="" width="175" height="200" border="0">&nbsp;&nbsp; <img src="../../../../Images/nonzero.png" alt="" width="175" height="200" border="0">&nbsp;&nbsp; <img src="../../../../Images/positive.png" alt="" width="175" height="200" border="0">&nbsp;&nbsp; <img src="../../../../Images/negative.png" alt="" width="175" height="200" border="0"><br><br> By far the most widely used fill rules are Even-Odd (aka Alternate) and Non-Zero (aka Winding). Most graphics rendering libraries (<a href="http://www.antigrain.com/__code/include/agg_basics.h.html#filling_rule_e">AGG</a>, <a href="http://developer.android.com/reference/android/graphics/Path.FillType.html">Android Graphics</a>, <a href="http://cairographics.org/manual/cairo-cairo-t.html#cairo-fill-rule-t">Cairo</a>, <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms534120(v=vs.85).aspx">GDI+</a>, <a href="http://www.glprogramming.com/red/chapter11.html">OpenGL</a>, <a href="http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_paths/dq_paths.html#//apple_ref/doc/uid/TP30001066-CH211-TPXREF101">Quartz 2D</a> etc) and vector graphics storage formats (<a href="http://www.w3.org/TR/SVG/painting.html#FillRuleProperty">SVG</a>, Postscript, <a href="http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/PhotoshopFileFormats.htm#50577409_17587">Photoshop</a> etc) support both these rules. However some libraries (eg Java's <a href="http://docs.oracle.com/javase/6/docs/api/java/awt/Graphics.html#fillPolygon(int[], int[], int)">Graphics2D</a>) only support one fill rule. <em>Android Graphics</em> and <em>OpenGL</em> are the only libraries (that I'm aware of) that support multiple filling rules.<br><br> It's useful to note that <em>edge direction</em> has no affect on a winding number's odd-ness or even-ness. (This is why <span class="maroon"><a href="../Functions/Orientation.htm">orientation</a> is ignored when the <em>Even-Odd</em> rule is employed.)</span><br><br> The direction of the Y-axis does affect polygon orientation and <em>edge direction</em>. However, changing Y-axis orientation will only change the <em>sign</em> of winding numbers, not their magnitudes, and has no effect on either <em>Even-Odd</em> or <em>Non-Zero</em> filling.<br><br> </p>
