FAQ

+ + +

Why does Clipper use integer coordinates, not floats?

+ +

This has been done to preserve numerical robustness. 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.

+ + +

How do I use floating point coordinates with Clipper?

+ +

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.

+ + +

Does Clipper handle polygons with holes?

+ +

'Holes' are defined by the specified polygon filling rule. (See also Clipper.Execute)

+ + +

Some polygons in the solution share a common edge. Is this a bug?

+ +

No, though this should happen rarely as of version 6. (See Clipper.Execute for more about this.)

+ + +

I have lots of polygons that I want to 'union'. Can I do this in one operation?

+ +

Yes. Just add all the polygons as subject polygons to the Clipper object. (You don't have to assign both subject and clip polygons.)

+ + +

The polygons produced by ClipperOffset have tiny artefacts? Could this be a bug?

+ +

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 CleanPolygon and CleanPolygons 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.

+ + +

Is there an easy way to reverse polygon orientations?

+ +

Yes, see ReversePaths.

+ +
 
+ + +

My drawings contain lots of beziers, ellipses and arcs. How can I perform clipping operations on these?

+ +

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.

Rounding

+ + +

By using an integer type for polygon coordinates, the Clipper Library has been able to avoid problems of numerical robustness that can cause havoc with geometric computations. Problems associated with integer rounding and their possible solutions are discussed below.

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.

The Clipper Library supports scaling to very high degrees of precision by accepting integer coordinate values in the range ±0x3FFFFFFFFFFFFFFF (± 4.6e+18).

Another complication of using a discrete numbers (as opposed to real numbers) is that very occasionally tiny self-intersection 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.

+ + +



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.

Although these tiny self-intersections are uncommon, if it's deemed necessary, they are best removed with CleanPolygons. (Setting Clipper's StrictlySimple 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.)

+ + +



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 StrictlySimple property to true avoids this uncommon problem.

Overview

+ + +

The Clipper Library performs clipping, and offsetting of both lines and polygons.

A number of features set Clipper apart from other clipping libraries: +

    + +
  • it accepts all types of polygons including self-intersecting ones
    • + +
  • it supports multiple polygon filling rules (EvenOdd, NonZero, Positive, Negative)
    • + +
  • it's very fast relative to other libraries
    • + +
  • it's numerically robust
    • + +
  • it also performs line and polygon offsetting
    • + +
  • it's free to use in both freeware and commercial applications
    • + +

Terminology:
+

    + +
  • Clipping: commonly refers to the process of cutting away from a set of 2-dimensional geometric shapes those parts that are outside a rectangular 'clipping' window. This can be achieved by intersecting 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 intersection operation, in this documentation it will refer to any one of the four boolean operations (intersection, union, difference and exclusive-or).
    • + +
  • Path: 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).
    • + +
  • Line: or polyline is an open path containing 2 or more vertices.
    • + +
  • Polygon: 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 closed path.
    • + +
  • Contour: synonymous with path.
    • + +
  • Hole: 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.
    • + +
  • Polygon Filling Rule: the filling rule, together with a list of closed paths, defines those regions (bounded by paths) that are inside (ie regions 'brush filled' in a graphical display) and those which are outside (ie 'holes').
    • + +

Distribution package contents:

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 Delphi Pascal (and compiles with Delphi version 7 or above) but now contains C++, C# and Python 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 - AGG, Cairo, OpenGL, Graphics32, GDI+ and SVG.

References:

The Library is based on but significantly extends Bala Vatti's polygon clipping algorithm as described in "A generic solution to polygon clipping", Communications of the ACM, Vol 35, Issue 7 (July 1992) pp 56-63.

A section in "Computer graphics and geometric modeling: implementation and algorithms" by By Max K. Agoston (Springer, 2005) discussing Vatti Polygon Clipping was also helpful in creating the initial Clipper implementation.

The paper titled "Polygon Offsetting by Computing Winding Numbers" 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.

+ +

Once subject and clip paths have been assigned (via AddPath and/or AddPaths), Execute can then perform the clipping operation (intersection, union, difference or XOR) specified by the clipType parameter.

The solution parameter can be either a Paths or PolyTree structure. The Paths structure is simpler than the PolyTree stucture. 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, the PolyTree structure preserves nested parent-child polygon relationships (ie outer polygons owning/containing holes and holes owning/containing other outer polygons etc). Also, only the PolyTree structure can differentiate between open and closed paths since each PolyNode has an IsOpen property. (The Path structure has no member indicating whether it's open or closed.) For this reason, when open paths are passed to a Clipper object, the user must use a PolyTree object as the solution parameter, otherwise an exception will be raised.

When a PolyTree object is used in a clipping operation on open paths, two ancilliary functions have been provided to quickly separate out open and closed paths from the solution - OpenPathsFromPolyTree and ClosedPathsFromPolyTree. PolyTreeToPaths is also available to convert path data to a Paths structure (irrespective of whether they're open or closed).

There are several things to note about the solution paths returned: +

    + +
  • they aren't in any specific order
    • + +
  • they should never overlap or be self-intersecting (but see notes on rounding)
    • + +
  • holes will be oriented opposite outer polygons
    • + +
  • the solution fill type can be considered either EvenOdd or NonZero since it will comply with either filling rule
    • + +
  • polygons may rarely share a common edge (though this is now very rare as of version 6)
    • + +


+ + +

The subjFillType and clipFillType parameters define the polygon fill rule 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.)

Execute can be called multiple times without reassigning subject and clip polygons (ie when different clipping operations are required on the same polygon sets).

By default, when three or more vertices are collinear in input polygons (subject or clip), the Clipper object removes the 'inner' vertices before clipping. When enabled the PreserveCollinear property prevents this default behavior to allow these inner vertices to appear in the solution.

Terminology:
+

    + +
  • A simple polygon is one that does not self-intersect.
    • + +
  • A weakly simple polygon is a simple polygon that contains 'touching' vertices, or 'touching' edges.
    • + +
  • A strictly simple polygon is a simple polygon that does not contain 'touching' vertices, or 'touching' edges.
    • + +

+ +

Vertices 'touch' if they share the same coordinates (and are not adjacent). An edge touches another if one of its end vertices touches another edge excluding its adjacent edges, or if they are co-linear and overlapping (including adjacent edges).

Polygons returned by clipping operations (see Clipper.Execute()) should always be simple polygons. When the StrictlySimply property is enabled, polygons returned will be strictly simple, otherwise they may be weakly simple. It's computationally expensive ensuring polygons are strictly simple and so this property is disabled by default.

Note: There's currently no guarantee that polygons will be strictly simple since 'simplifying' is still a work in progress.


+ + +

In the image above, the two examples show weakly simple polygons being broken into two strictly simple polygons. (The outlines with arrows are intended to aid visualizing vertex order.)

This property is only exposed when the pre-processor directive use_xyz has been defined. If this is the case, a 'Z' member will be included in the IntPoint structure where users can store custom data. While most vertices in a clipping solution will correspond to input (subject and clip) vertices, there will also be new vertices wherever edges intersect. This property assigns a custom callback function to the Clipper object so that custom 'Z' values can be assigned to these intersection vertices. (Note that 'Z' values in the solution at non-intersecting vertices will simply be copied from matching input vertices along with the X and Y values.)

It is up to the library user to assign 'Z' values for new intersection vertices (otherwise these values will remain 0). The four vertices that define the intersecting line segments will be passed to the callback function (together with the new intersection vertex) to aid the user in determining appropriate Z values.

ClipperBase

+
+ +

The Clipper class encapsulates boolean operations on polygons (intersection, union, difference and XOR), which is also called polygon clipping.

Input polygons, both subject and clip sets, are passed to a Clipper object by its AddPath and AddPaths methods, and the clipping operation is performed by calling its Execute method. Multiple boolean operations can be performed on the same input polygon sets by repeat calls to Execute.

+
+ + +

Any number of subject and clip paths can be added to a clipping task, either individually via the AddPath() method, or as groups via the AddPaths() method, or even using both methods.

'Subject' paths may be either open (lines) or closed (polygons) or even a mixture of both, but 'clipping' paths must always be closed. Clipper allows polygons to clip both lines and other polygons, but doesn't allow lines to clip either lines or polygons.

With closed paths, orientation should conform with the filling rule that will be passed via Clippper's Execute method.

+ + + +

Path Coordinate range:
Path coordinates must be between ± 0x3FFFFFFFFFFFFFFF (± 4.6e+18), otherwise a range error will be thrown when attempting to add the path to the Clipper object. If coordinates can be kept between ± 0x3FFFFFFF (± 1.0e+9), a modest increase in performance (approx. 15-20%) over the larger range can be achieved by avoiding large integer math. If the preprocessor directive use_int32 is defined (allowing a further increase in performance of 20-30%), then the maximum range is restricted to ± 32,767.

+ + +

Return Value:
The function will return false if the path is invalid for clipping. A path is invalid for clipping when: +

  • it has less than 2 vertices

The second parameter is the amount to which the supplied paths will be offset. Negative delta values shrink polygons and positive delta expand them.

Firstly, this field/property is only relevant when JoinType = jtRound and/or EndType = etRound.

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.

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).

Reducing tolerances below 0.25 will not improve smoothness since vertex coordinates will still be rounded to integer values. The only way to achieve sub-integer precision is through coordinate scaling before and after offsetting (see example below).

It's important to make ArcTolerance a sensible fraction of the offset delta (arc radius). 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.

Example: Imagine a set of polygons (defined in floating point coordinates) that is to be offset by 10 units using round joins, and the solution is to retain floating point precision up to at least 6 decimal places.
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 108 + (and rounded to integers) prior to offsetting. Both offset delta and ArcTolerance will also need to be scaled by this same factor. If ArcTolerance was left unscaled at the default 0.25 units, every arc in the solution would contain a fraction of 44 THOUSAND vertices while the final arc imprecision would be 0.25 × 10-8 + units (ie once scaling was reversed). However, if 0.1 units was an acceptable imprecision in the final unscaled solution, then ArcTolerance should be set to 0.1 × scaling_factor (0.1 × 108 + ). 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.

The formula for the number of steps in a full circular arc is ... Pi / acos(1 - arc_tolerance / abs(delta))

This property sets the maximum distance in multiples of delta that vertices can be offset from their original positions before squaring is applied. (Squaring truncates a miter by 'cutting it off' at 1 × delta distance from the original vertex.)

The default value for MiterLimit is 2 (ie twice delta). This is also the smallest MiterLimit that's allowed. If mitering was unrestricted (ie without any squaring), then offsets at very acute angles would generate unacceptably long 'spikes'.

An example of an offsetting 'spike' at a narrow angle that's a consequence of using a large MiterLimit (25) ...

ClipperOffset

+
+ +

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.

(This class replaces the now deprecated OffsetPaths function which was less flexible.)

Preconditions for offsetting:
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.
2. Polygons must not self-intersect.

Limitations:
When offsetting, small artefacts may appear where polygons overlap. To avoid these artefacts, offset overlapping polygons separately.

PolyNode

+
+ +

PolyNodes are encapsulated within a PolyTree container, and together provide a data structure representing the parent-child relationships of polygon contours returned by Clipper's Execute method.

A PolyNode object represents a single polygon. Its IsHole property indicates whether it's an outer or a hole. PolyNodes may own any number of PolyNode children (Childs), where children of outer polygons are holes, and children of holes are (nested) outer polygons.

PolyNode

+
+ +

PolyTree is intended as a read-only data structure that should only be used to receive solutions from clipping and offsetting operations. It's an alternative to the Paths data structure which also receives these solutions. PolyTree's two major advantages over the Paths structure are: it properly represents the parent-child relationships of the returned polygons; it differentiates between open and closed paths. However, since PolyTree is a more complex structure than the Paths structure, and since it's more computationally expensive to process (the Execute method being roughly 5-10% slower), it should used only be when parent-child polygon relationships are needed, or when open paths are being 'clipped'.

An empty PolyTree object can be passed as the solution parameter in Clipper.Execute and in ClipperOffset.Execute. Once the clipping or offseting operation is completed, the method returns with the PolyTree structure filled with data representing the solution.

A PolyTree object is a container for any number of PolyNode children, with each contained PolyNode representing a single polygon contour (either an outer or hole polygon). PolyTree itself is a specialized PolyNode whose immediate children represent the top-level outer polygons of the solution. (Its own Contour property is always empty.) 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 outers will always be holes, and children of holes will always be outers.

PolyTrees can also contain open paths. Open paths will always be represented by top level PolyNodes. Two functions are provided to quickly separate out open and closed paths from a polytree - OpenPathsFromPolyTree and ClosedPathsFromPolyTree.

Minkowski Difference is performed by subtracting each point in a polygon from the set of points in an open or closed path. A key feature of Minkowski Difference is that when it's applied to two polygons, the resulting polygon will contain the coordinate space origin whenever the two polygons touch or overlap. (This function is often used to determine when polygons collide.)

In the image on the left the blue polygon is the 'minkowski difference' of the two red boxes. The black dot represents the coordinate space origin.

Minkowski Addition is performed by adding each point in a polygon 'pattern' to the set of points in an open or closed path. The resulting polygon (or polygons) defines the region that the 'pattern' would pass over in moving from the beginning to the end of the 'path'.

Orientation is only important to closed paths. Given that vertices are declared in a specific order, orientation refers to the direction (clockwise or counter-clockwise) that these vertices progress around a closed path.

Orientation is also dependent on axis direction:
+

    + +
  • On Y-axis positive upward displays, Orientation will return true if the polygon's orientation is counter-clockwise.
    • + +
  • On Y-axis positive downward displays, Orientation will return true if the polygon's orientation is clockwise.
    • + +

+ + +



Notes:
+

    + +
  • Self-intersecting polygons have indeterminate orientations in which case this function won't return a meaningful value.
    • + +
  • The majority of 2D graphic display libraries (eg GDI, GDI+, XLib, Cairo, AGG, Graphics32) and even the SVG file format have their coordinate origins at the top-left corner of their respective viewports with their Y axes increasing downward. However, some display libraries (eg Quartz, OpenGL) have their coordinate origins undefined or in the classic bottom-left position with their Y axes increasing upward.
    • + +
  • For Non-Zero filled polygons, the orientation of holes must be opposite that of outer polygons.
    • + +
  • For closed paths (polygons) in the solution returned by Clipper's Execute method, their orientations will always be true for outer polygons and false for hole polygons (unless the ReverseSolution property has been enabled).

cInt is the integer type used by the Clipper Library to represent vertex coordinate values. (See also IntPoint.)

The library uses integers instead of floating point values to preserve numerical robustness. (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.)

By default cInt 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.

If the preprocessor directive use_int32 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.

There are four boolean operations - AND, OR, NOT & XOR.

Given that subject and clip polygon brush 'filling' is defined both by their vertices and their respective filling rules, the four boolean operations can be applied to polygons to define new filling regions: +

    + +
  • AND (intersection) - create regions where both subject and clip polygons are filled
    • + +
  • OR (union) - create regions where either subject or clip polygons (or both) are filled
    • + +
  • NOT (difference) - create regions where subject polygons are filled except where clip polygons are filled
    • + +
  • XOR (exclusive or) - create regions where either subject or clip polygons are filled but not where both are filled
    • + +

+ + +


     

All polygon clipping is performed with a Clipper object with the specific boolean operation indicated by the ClipType parameter passed in its Execute method.


+ + +

With regard to open paths (polylines), clipping rules generally match those of closed paths (polygons).
However, when there are both polyline and polygon subjects, the following clipping rules apply: +

    + +
  • union operations - polylines will be clipped by any overlapping polygons so that non-overlapped portions will be returned in the solution together with the union-ed polygons
    • + +
  • intersection, difference and xor operations - polylines will be clipped only by 'clip' polygons and there will be not interaction between polylines and subject polygons.
    • + +


+ + +

The IntPoint structure is used to represent all vertices in the Clipper Library. An integer storage type has been deliberately chosen to preserve numerical robustness. (Early versions of the library used floating point coordinates, but it became apparent that floating point imprecision would always cause occasional errors.)

A sequence of IntPoints are contained within a Path structure to represent a single contour.

As of version 6, IntPoint now has an optional third member 'Z'. This can be enabled by exposing (ie uncommenting) the PreProcessor define 'use_xyz'. 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 callback function.

Users wishing to clip or offset polygons containing floating point coordinates need to use appropriate scaling when converting these values to and from IntPoints.

When adding paths to a ClipperOffset object via the AddPaths method, the joinType parameter may be one of three types - jtMiter, jtSquare or jtRound.

    + +
  • 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 MiterLimit property specifies a maximum distance that vertices will be offset (in multiples of delta). For any given edge join, when miter offsetting would exceed that maximum distance, 'square' joining is applied.
    • + +
  • jtRound: While flattened paths can never perfectly trace an arc, they are approximated by a series of arc chords (see ClipperObject's ArcTolerance property).
    • + +
  • jtSquare: Squaring is applied uniformally at all convex edge joins at 1 × delta.

This structure contains a sequence of IntPoint vertices defining a single contour (see also terminology). Paths may be open and represent a series of line segments bounded by 2 or more vertices, or they may be closed and represent polygons. Whether or not a path is open depends on context. Closed paths may be 'outer' contours or 'hole' contours. Which they are depends on orientation.

Multiple paths can be grouped into a Paths structure.

This structure is fundamental to the Clipper Library. It's a list or array of one or more Path structures. (The Path structure contains an ordered list of vertices that make a single contour.)

Paths may open (a series of line segments), or they may closed (polygons). Whether or not a path is open depends on context. Closed paths may be 'outer' contours or 'hole' contours. Which they are depends on orientation.

Filling indicates those regions that are inside a closed path (ie 'filled' with a brush color or pattern in a graphical display) and those regions that are outside. The Clipper Library supports 4 filling rules: Even-Odd, Non-Zero, Positive and Negative.

The simplest filling rule is Even-Odd filling (sometimes called alternate 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 not filled. Likewise, each time a path is crossed, filling starts if it had stopped and stops if it had started.

With the exception of Even-Odd filling, all other filling rules rely on edge direction and winding numbers 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 winding number of each polygon subregion.

The winding number for each polygon sub-region can be derived by:

    + +
  1. starting with a winding number of zero and
    2. + +
  2. from a point (P1) that's outside all polygons, draw an imaginary line to a point that's inside a given sub-region (P2)
    3. + +
  3. 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.
    4. + +
  4. Once you arrive at the given sub-region you have its winding number.
    5. + +

+ +


Even-Odd (Alternate): Odd numbered sub-regions are filled, while even numbered sub-regions are not.
Non-Zero (Winding): All non-zero sub-regions are filled.
Positive: All sub-regions with winding counts > 0 are filled.
Negative: All sub-regions with winding counts < 0 are filled.

Paths are added to a Clipper object using the AddPath or AddPaths methods and the filling rules (for subject and clip polygons separately) are specified in the Execute method.

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.

        

By far the most widely used fill rules are Even-Odd (aka Alternate) and Non-Zero (aka Winding). Most graphics rendering libraries (AGG, Android Graphics, Cairo, GDI+, OpenGL, Quartz 2D etc) and vector graphics storage formats (SVG, Postscript, Photoshop etc) support both these rules. However some libraries (eg Java's Graphics2D) only support one fill rule. Android Graphics and OpenGL are the only libraries (that I'm aware of) that support multiple filling rules.

It's useful to note that edge direction has no affect on a winding number's odd-ness or even-ness. (This is why orientation is ignored when the Even-Odd rule is employed.)

The direction of the Y-axis does affect polygon orientation and edge direction. However, changing Y-axis orientation will only change the sign of winding numbers, not their magnitudes, and has no effect on either Even-Odd or Non-Zero filling.

Boolean (clipping) operations are mostly applied to two sets of Polygons, represented in this library as subject and clip polygons. Whenever Polygons are added to the Clipper object, they must be assigned to either subject or clip polygons.

UNION operations can be performed on one set or both sets of polygons, but all other boolean operations require both sets of polygons to derive meaningful solutions.

If the use_xyz pre-processor directive is enabled, then the IntPoint class will have an extra 'Z' member and the Clipper class's ZFillFunction property will be exposed so it can be assigned a custom callback function.

This custom callback procedure requires five IntPoint parameters: the first 2 parameters are the vertices that define one line segment involved in the intersection and the next two parameters the other line segment. (Since the Clipper library has been developed in an environment that uses an inverted Y axis display, e1bot and e2bot will always have Y values greater than or equal to their corresponding e1top and e2top Y values.) The last IntPoint parameter contain the actual coordinates at the intersection. This last parameter is passed by reference so that its Z member can be assigned with a custom value.
