CGAL::create_offset_polygons_2

The function create_offset_polygons_2 creates a straight skeleton in the interior of a 2D polygon with holes.

template<class Polygon, class FT, class Straight_skeleton, class K>

std::vector< boost::shared_ptr<Polygon> >

create_offset_polygons_2 ( FT offset,
Straight_skeleton s,
,
K k = Exact_predicates_inexact_constructions_kernel)

returns a container with all the offset polygons at distance offset obtained from the straight skeleton s.

K is any CGAL kernel.
FT is any number type implicitly convertible to K::FT.
Straight_skeleton is Straight_skeleton_2<K2>. If K != K2 the straight skeleton is converted to Straight_skeleton_2<K>.
Polygon is a model of VertexContainer_2. If this first template parameter is omitted, Polygon_2 is used.
