## Definition

The class `Straight_skeleton_converter_2` 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 `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.

## Types

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.

## Creation

| Straight_skeleton_converter_2 (Items_converter const &c)
| Default constructor .

## Operations

boost::shared_ptr < Target_skeleton > | 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.
