- Detailed description

A polygon consists of an outer hull and zero to many holes. Each contour consists of several points. The point list is normalized such that the leftmost, lowest point is the first one. The orientation is normalized such that the orientation of the hull contour is clockwise, while the orientation of the holes is counterclockwise.

It is in no way checked that the contours are not overlapping. This must be ensured by the user of the object when filling the contours.

A polygon can be asked for the number of holes using the holes method. each_point_hull delivers the points of the hull contour. each_point_hole delivers the points of a specific hole. each_edge delivers the edges (point-to-point connections) of both hull and holes. bbox delivers the bounding box, area the area and perimeter the perimeter of the polygon.

Here's an example of how to create a polygon:

hull = [ RBA::Point::new(0, 0), RBA::Point::new(6000, 0), RBA::Point::new(6000, 3000), RBA::Point::new(0, 3000) ] hole1 = [ RBA::Point::new(1000, 1000), RBA::Point::new(2000, 1000), RBA::Point::new(2000, 2000), RBA::Point::new(1000, 2000) ] hole2 = [ RBA::Point::new(3000, 1000), RBA::Point::new(4000, 1000), RBA::Point::new(4000, 2000), RBA::Point::new(3000, 2000) ] poly = RBA::Polygon::new(hull) poly.insert_hole(hole1) poly.insert_hole(hole2) # ask the polygon for some properties poly.holes # -> 2 poly.area # -> 16000000 poly.perimeter # -> 26000 poly.bbox # -> (0,0;6000,3000)

The Polygon class stores coordinates in integer format. A class that stores floating-point coordinates is DPolygon.

## == |
| ||||||||

## PO_any |
This value indicates that there is not cut preference This constant has been introduced in version 0.25. | ||||||||

## PO_horizontal |
This value indicates that there only horizontal cuts are allowed This constant has been introduced in version 0.25. | ||||||||

## PO_htrapezoids |

## PO_vtrapezoids |
This value indicates that cuts shall favor decomposition into vertical trapezoids This constant has been introduced in version 0.25. | ||||||||

## TD_htrapezoids |
This value indicates simple decomposition mode. This mode produces horizontal trapezoids and tries to minimize the number of trapezoids. This constant has been introduced in version 0.25. | ||||||||

## TD_simple |
This value indicates simple decomposition mode. This mode is fast but does not make any attempts to produce less trapezoids. This constant has been introduced in version 0.25. | ||||||||

## TD_vtrapezoids |
This value indicates simple decomposition mode. This mode produces vertical trapezoids and tries to minimize the number of trapezoids. | ||||||||

## _create |
Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. | ||||||||

## _destroy |
Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | ||||||||

## _destroyed? |
This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. | ||||||||

## _is_const_object? |
This method returns true, if self is a const reference. In that case, only const methods may be called on self. | ||||||||

## _manage |
After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. | ||||||||

## _unmanage |
Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. | ||||||||

## area |
The area is correct only if the polygon is not self-overlapping and the polygon is oriented clockwise.Orientation is ensured automatically in most cases. | ||||||||

## area2 |
This method is provided because the area for an integer-type polygon is a multiple of 1/2. Hence the double area can be expresses precisely as an integer for these types. This method has been introduced in version 0.26.1 | ||||||||

## assign |
| ||||||||

## assign_hole |
If the hole index is not valid, this method does nothing. This method was introduced in version 0.18. The 'raw' argument was added in version 0.24. | ||||||||

If the hole index is not valid, this method does nothing. This method was introduced in version 0.23. | |||||||||

## assign_hull |
If the 'raw' argument is set to true, the points are taken as they are. Specifically no removal of redundant points or joining of coincident edges will take place. In effect, polygons consisting of a single point or two points can be constructed as well as polygons with duplicate points. Note that such polygons may cause problems in some applications. Regardless of raw mode, the point list will be adjusted such that the first point is the lowest-leftmost one and the orientation is clockwise always. The 'assign_hull' variant is provided in analogy to 'assign_hole'. The 'raw' argument was added in version 0.24. | ||||||||

## bbox |
The bounding box is the box enclosing all points of the polygon. | ||||||||

## compress |
This method removes redundant points from the polygon, such as points being on a line formed by two other points. If remove_reflected is true, points are also removed if the two adjacent edges form a spike. This method was introduced in version 0.18. | ||||||||

## create |
Use of this method is deprecated. Use _create instead Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. | ||||||||

## decompose_convex |
This method returns a decomposition of the polygon that contains convex pieces only. If the polygon was convex already, the list returned has a single element which is the original polygon. This method was introduced in version 0.25. | ||||||||

## decompose_trapezoids |
This method returns a decomposition of the polygon into trapezoid pieces. It supports different modes for various applications. See the TD_... constants for details. This method was introduced in version 0.25. | ||||||||

## destroy |
Use of this method is deprecated. Use _destroy instead Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | ||||||||

## destroyed? |
Use of this method is deprecated. Use _destroyed? instead This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. | ||||||||

## dup |
| ||||||||

## each_edge |
This iterator will deliver all edges, including those of the holes. Hole edges are oriented counterclockwise while hull edges are oriented clockwise. | ||||||||

This iterator will deliver all edges of the contour specified by the contour parameter. The hull has contour number 0, the first hole has contour 1 etc. Hole edges are oriented counterclockwise while hull edges are oriented clockwise. This method was introduced in version 0.24. | |||||||||

## each_point_hole |
The hole number must be less than the number of holes (see holes) | ||||||||

## each_point_hull |
| ||||||||

## ellipse |
This method has been introduced in version 0.23. | ||||||||

## extract_rad |
Attempts to extract the radii of rounded corner polygon. This is essentially the inverse of the round_corners method. If this method succeeds, if will return an array of four elements: - The polygon with the rounded corners replaced by edgy ones
- The radius of the inner corners
- The radius of the outer corners
- The number of points per full circle
This method is based on some assumptions and may fail. In this case, an empty array is returned. If successful, the following code will more or less render the original polygon and parameters p = ... # some polygon p.round_corners(ri, ro, n) (p2, ri2, ro2, n2) = p.extract_rad # -> p2 == p, ro2 == ro, ri2 == ri, n2 == n (within some limits) This method was introduced in version 0.25. | ||||||||

## is_rectilinear? |
| ||||||||

## minkowski_sum |

## round_corners |
Replaces the corners of the polygon with circle segments. This method was introduced in version 0.20 for integer coordinates and in 0.25 for all coordinate types. | ||||||||

## size |
Shifts the contour outwards (dx,dy>0) or inwards (dx,dy<0). dx is the sizing in x-direction and dy is the sizing in y-direction. The sign of dx and dy should be identical. The sizing operation create invalid (self-overlapping, reverse oriented) contours. The mode defines at which bending angle cutoff occurs (0:>0, 1:>45, 2:>90, 3:>135, 4:>approx. 168, other:>approx. 179) In order to obtain a proper polygon in the general case, the sized polygon must be merged in 'greater than zero' wrap count mode. This is necessary since in the general case, sizing can be complicated operation which lets a single polygon fall apart into disjoint pieces for example. This can be achieved using the EdgeProcessor class for example: poly = ... # a RBA::Polygon poly.size(-50, 2) ep = RBA::EdgeProcessor::new # result is an array of RBA::Polygon objects result = ep.simple_merge_p2p([ poly ], false, false, 1) | ||||||||

## split |
This method will break the polygon into parts. The exact breaking algorithm is unspecified, the result are smaller polygons of roughly equal number of points and 'less concave' nature. Usually the returned polygon set consists of two polygons, but there can be more. The merged region of the resulting polygons equals the original polygon with the exception of small snapping effects at new vertexes. The intended use for this method is a iteratively split polygons until the satisfy some maximum number of points limit. This method has been introduced in version 0.25.3. | ||||||||
