The class Straight_skeleton_converter_2<SrcSs,TgtSs,ItemsCvt> converts a straight skeleton instantiated using certain traits into another straight skeleton instantiated using a different traits.

The first and second template parameters are the source and target straight skeleton types, resp.

The third template parameter ItemsConverter is a function object that must model the concept StraightSkeletonItemsConverter_2. The default value of this parameter is CGAL::Straight_skeleton_items_converter_2<SrcSs,TgtSs>.

This conversion can be used to produce a straight skeleton with the fast Exact_predicates_inexact_constructions_kernel but then input that skeleton into Polygon_offset_builder<Ss,Gt,Container> instantiated with the slower Exact_predicates_exact_constructions_kernel obtaining only simple offset polygons without paying the runtime overhead of exact constructions for the straight skeleton itself.


SrcSs Source_skeleton; The SrcSs template parameter corresponding to the source straight skeleton.
TgtSs Target_skeleton; The TgtSs template parameter corresponding to the target straight skeleton.
ItemsCvt Items_converter; The ItemsCvt template parameter corresponding to the items converter.

#include <CGAL/Straight_skeleton_converter_2.h>


Straight_skeleton_converter_2<SrcSs,TgtSs,ItemsCvt> c ( Items_converter c);
Default constructor


c.operator() ( Source_skeleton const& s) const
returns a new straight skeleton data structure with the same combinatorial and geometric data as s using the items converter to convert the geometric embeeding to the types of the target traits.
