Complement Functions

The complement function is overloaded. Depending on the type of polygon pgn the complement is either a single (general) polygon with holes, or several (general) poylgons with holes. In the latter case the complement function writes them into an output iterator oi.

Parameters

pgn	The input polygon for the complement function. It may be of the type Polygon_2, General_polygon_2, Polygon_with_holes_2, or General_polygon_with_holes_2.

Function Documentation

complement() [1/2]

template<class Traits , class OutputIterator >

OutputIterator CGAL::complement	(	const Polygon_with_holes_2< Kernel, Container > &	pgn,
		OutputIterator	oi
	)

#include <CGAL/Boolean_set_operations_2.h>

writes the complement of the polygon with holes pgn into the output iterator oi.

The value type of oi is Polygon_with_holes_2.

complement() [2/2]

template<class Traits , class OutputIterator >

OutputIterator CGAL::complement	(	const General_polygon_with_holes_2< General_polygon_2< Traits > > &	pgn,
		OutputIterator	oi
	)

#include <CGAL/Boolean_set_operations_2.h>

writes the complement of the general polygon with holes pgn into the output iterator oi.

The value type of oi is General_polygon_with_holes_2.
