+ <ul class="dots">
+Input polygon coordinates can now contain the full range of signed
+64bit integers (ie +/-9,223,372,036,854,775,807). This means that
+floating point values can be converted to and from Clipper's 64bit
+vertex structure (<a href="../Units/ClipperLib/Types/IntPoint.htm">IntPoint</a>)
+and still retain a precision of up to 18 decimal places. However, since
+the large-integer math that supports this expanded range imposes a
+small cost on performance (~15%), a new property UseFullCoordinateRange
+has been added to the Clipper class to allow users the choice of
+whether or not to use this expanded coordinate range. If this property
+is disabled, coordinate values are restricted to +/-1,500,000,000. (By
+default, this property is enabled.)

+
+ <li>
+ <h2>v4.0 (4 April 2011)</h2>
+ <ul>
+
+ <li>
+ <h2>Major update:</h2>
+ <ul class="dots">
+Clipper is a major rewrite of earlier versions. The biggest change is
+that floating point values are no longer used, except for the storing
+of edge slope values. The main benefit of this is the issue of
+numerical robustness has been addressed. Due to other major code
+improvements Clipper v4 is approximately 40% faster than Clipper v3.
+
+ </ul> </li>
+
+ <li>
+ <h2>Changes:</h2>
+ <ul class="dots">
+The AddPolyPolygon method has been renamed to AddPolygons, and the
+IgnoreOrientation property has been removed. The clipper_misc library
+has been merged back into the clipper library.

+ <h1>FAQ</h1>
+
+
+ <p class="Decl5">Why does Clipper use integer coordinates, not floats?</p>
+
+ <p class="Decl4">This has been done to preserve <a href="http://www.mpi-inf.mpg.de/~kettner/pub/nonrobust_cgta_06.pdf" target="_blank">numerical robustness</a>. Early versions of the library did use floating point coordinates, but it became apparent that floating point imprecision was always going to cause occasional errors.<br><br> </p>
+
+
+ <p class="Decl5">How do I use floating point coordinates with Clipper?</p>
+
+ <p class="Decl4">It's a simple task to multiply your floating point coordinates by a scaling factor (that's typically a power of 10 depending on the desired precision). Then with the solution paths, divide the returned coordinates by this same scaling factor. Clipper accepts integer coordinates as large as ±4.6e18, so it can accommodate very large scaling.<br><br> </p>
+
+
+ <p class="Decl5">Does Clipper handle polygons with holes?</p>
+
+ <p class="Decl4">'Holes' are defined by the specified <a href="../Units/ClipperLib/Types/PolyFillType.htm">polygon filling rule</a>. (See also <a href="../Units/ClipperLib/Classes/Clipper/Methods/Execute.htm">Clipper.Execute</a>)<br><br> </p>
+
+
+ <p class="Decl5">Some polygons in the solution share a common edge. Is this a bug?</p>
+
+ <p class="Decl4"> No, though this should happen rarely as of version 6. (See <a href="../Units/ClipperLib/Classes/Clipper/Methods/Execute.htm">Clipper.Execute</a> for more about this.)<br><br> </p>
+
+
+ <p class="Decl5">I have lots of polygons that I want to 'union'. Can I do this in one operation?</p>
+
+ <p class="Decl4"> Yes. Just add all the polygons as subject polygons to the Clipper object. (You don't have to assign both subject and clip polygons.)<br><br> </p>
+
+
+ <p class="Decl5"> <img src="../../Images/kangaroo_small.png" width="292" height="292" alt="" align="right"> The polygons produced by <a href="../Units/ClipperLib/Classes/ClipperOffset/_Body.htm">ClipperOffset</a> have tiny artefacts? Could this be a bug?</p>
+
+ <p class="Decl4"> Make sure the input polygons don't self-intersect. Tiny self-intersections can sometimes be produced by previous clipping operations. These can be cleaned up using the <a href="../Units/ClipperLib/Functions/CleanPolygon.htm">CleanPolygon</a> and <a href="../Units/ClipperLib/Functions/CleanPolygons.htm">CleanPolygons</a> functions. Also, make sure the supplied polygons don't overlap. If they do, offset these separately. Finally, the precision of the input coordinates may be a problem. Because the Clipper Library only operates on integer coordinates, you may need to scale your coordinates (eg by a factor of 10) to improve precision. <br><br> </p>
+
+
+ <p class="Decl5">Is there an easy way to reverse polygon orientations?</p>
+
+ <p class="Decl4"> Yes, see <a href="../Units/ClipperLib/Functions/ReversePaths.htm">ReversePaths</a>. <br><br> </p>
+
+<div style="clear:both"> </div>
+
+
+ <p class="Decl5">My drawings contain lots of beziers, ellipses and arcs. How can I perform clipping operations on these?</p>
+
+ <p class="Decl4"> You'll have to convert them to 'flattened' paths. For an example of how this can be done (and even reconstructed back into beziers, arcs etc), see the CurvesDemo application included in this library. <br><br> </p>

+ <h1>Rounding</h1>
+
+
+ <p class="Body"> By using an integer type for polygon coordinates, the Clipper Library has been able to avoid problems of <a href="http://www.mpi-inf.mpg.de/~kettner/pub/nonrobust_cgta_06.pdf"><b>numerical robustness</b></a> that can cause havoc with geometric computations. Problems associated with integer <b>rounding</b> and their possible solutions are discussed below.<br><br> <img src="../../Images/clipper_rounding.png" width="488" height="365" alt="" align="left"> <span class="maroon">It's important to stress at the outset that rounding causes vertices to move fractions of a unit away from their 'true' positions. Nevertheless, the resulting imprecision can be very effectively managed by appropriate scaling.</span><br><br> The Clipper Library supports scaling to <span class="maroon">very high degrees of precision</span> by accepting integer coordinate values in the range ±0x3FFFFFFFFFFFFFFF (± 4.6e+18).<br><br> Another complication of using a discrete numbers (as opposed to <a href="http://en.wikipedia.org/wiki/Real_number" target="_blank">real numbers</a>) is that very occasionally tiny <b>self-intersection</b> artefacts arise. In the unscaled image on the left (where one unit equals one pixel), the area of intersection of two polygons has been highlighted in bright green.<br><br> </p>
+
+
+ <p class="Body" style="clear='both'"> <img src="../../Images/clipper_rounding2.png" width="440" height="316" alt="" align="right"><br><br> A 30X 'close up' of the lower points of intersection of these same two polygons shows the presence of a tiny self-intersecting artefact. The three 'black dots' highlight the actual points of intersection (with their fractional coordinates displayed). The 'red dots' show where these points of intersection are located once rounding is applied. With a little care you can see that rounding reverses the orientation of these vertices and causes a tiny self-intersecting artefact.<br><br> Although these tiny self-intersections are uncommon, if it's deemed necessary, they are best removed with <a href="../Units/ClipperLib/Functions/CleanPolygons.htm">CleanPolygons</a>. (Setting Clipper's <a href="../Units/ClipperLib/Classes/Clipper/Properties/StrictlySimple.htm">StrictlySimple</a> property to true would also address this self-intersection but the tiny (sub-unit) polygon 'artefact' with incorrect orientation would still appear in the solution.) <br><br> </p>
+
+
+ <p class="Body" style="clear='both'"> <img src="../../Images/clipper_rounding4.png" width="292" height="224" alt="" align="left"><br><br> In this final example, the single polygon on the left also has a tiny self-intersection. However, the clipping algorithm sees this vertex (88,50) as simply 'touching' rather than intersecting the right edge of the polygon (though only by a fraction of a unit). Since this intersection won't normally be detected, the clipping solution (eg following a union operation) will still contain this tiny self-intersection. Setting Clipper's <a href="../Units/ClipperLib/Classes/Clipper/Properties/StrictlySimple.htm">StrictlySimple</a> property to true avoids this uncommon problem.<br><br> </p>

+
+ <p class="Body" id="terminology"> <img src="../../Images/int.png" alt="" border="0" align="right"> <b>Terminology:</b><br>
+ <ul>
+
+ <li><b>Clipping:</b> commonly refers to the process of cutting away from a set of 2-dimensional geometric shapes those parts that are outside a rectangular '<em>clipping</em>' window. This can be achieved by <em>intersecting</em> subject paths (lines and polygons) with a clipping rectangle. In a more general sense, the clipping window need not be rectangular but can be any type of polygon, even multiple polygons. Also, while clipping typically refers to an <em>intersection</em> operation, in this documentation it will refer to any one of the <a href="../Units/ClipperLib/Types/ClipType.htm">four boolean operations</a> (intersection, union, difference and exclusive-or).</li>
+
+ <li><b>Path:</b> is an ordered sequence of vertices defining a single geometric contour that's either a line (an open path) or a polygon (a closed path).</li>
+
+ <li><b>Line:</b> or polyline is an <em>open</em> path containing 2 or more vertices.</li>
+
+ <li><b>Polygon:</b> commonly refers to a two-dimensional region bounded by an outer non-intersecting closed contour. That region may also contain a number of 'holes'. In this documentation however, polygon will simply refer to a <em>closed</em> path.</li>
+
+ <li><b>Contour:</b> synonymous with path.</li>
+
+ <li><b>Hole:</b> is a closed region within a polygon that's not part of the polygon. A 'hole polygon' is a closed path that forms the outer boundaries of a hole.</li>
+
+ <li><b>Polygon Filling Rule:</b> the <a href="../Units/ClipperLib/Types/PolyFillType.htm"><b>filling rule</b></a>, together with a list of closed paths, defines those regions (bounded by paths) that are <em>inside</em> (ie regions 'brush filled' in a graphical display) and those which are <em>outside</em> (ie 'holes').</li>
+
+ </ul><br> </p>
+
+
+ <p class="Body"> <b>Distribution package contents:</b><br><br> The ZIP package contains the Clipper library's source code, a Windows CHM help file, HTML help, and a number of compiled demo applications (with full source code). The library was initially written in <strong>Delphi Pascal</strong> (and compiles with Delphi version 7 or above) but now contains <strong>C++</strong>, <strong>C#</strong> and <strong>Python</strong> translations too. The library's source code in each language is about 5000 lines. The Delphi code contains reasonably extensive comments, but comments are fewer in the C++ and C# code. The included sample applications show how Clipper can be used with the different languages using a number of graphics display libraries including - <b>AGG, Cairo, OpenGL, Graphics32, GDI+</b> and <b>SVG</b>.<br><br> <b>Download Link:</b><br><br> <a href="http://sourceforge.net/projects/polyclipping">SourceForge</a><br><br> <b>References:</b><br><br> The Library is based on but significantly extends Bala Vatti's polygon clipping algorithm as described in <a href="http://portal.acm.org/citation.cfm?id=129906" target="_blank">"A generic solution to polygon clipping"</a>, Communications of the ACM, Vol 35, Issue 7 (July 1992) pp 56-63.<br><br> A section in <a href="http://books.google.com/books?q=vatti+clipping+agoston" target="_blank">"Computer graphics and geometric modeling: implementation and algorithms"</a> by By Max K. Agoston (Springer, 2005) discussing <em>Vatti Polygon Clipping</em> was also helpful in creating the initial Clipper implementation.<br><br> The paper titled <a href="http://www.me.berkeley.edu/~mcmains/pubs/DAC05OffsetPolygon.pdf">"Polygon Offsetting by Computing Winding Numbers"</a> by Chen & McMains (Paper no. DETC2005-85513, ASME 2005. Pages 565-575) contains helpful discussion on the complexities of polygon offsetting together with some solutions.<br><br> </p>

+ <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.

+
+ <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">

(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 ± 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 ± 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 ± 46340. </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 > 0 are filled.<br> <b>Negative</b>: All sub-regions with winding counts < 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"> <img src="../../../../Images/nonzero.png" alt="" width="175" height="200" border="0"> <img src="../../../../Images/positive.png" alt="" width="175" height="200" border="0"> <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>

This last parameter is passed by reference so that its Z member can be assigned with a custom value.<br><br> </p>
