##### Boost.Polygon's rectangle_data

Boost.Polygon's rectangle type (boost::polygon::rectangle_data) is adapted to the Boost.Geometry Point Concept.

###### Description

Boost.Polygon's points (as well as polygons) can be used by Boost.Geometry. The two libraries can therefore be used together. Using a boost::polygon::rectangle_data<...>, algorithms from both Boost.Polygon and Boost.Geometry can be called.

###### Model of

Box Concept

###### Header

`#include <boost/geometry/geometries/adapted/boost_polygon.hpp>`

The standard header `boost/geometry.hpp` does not include this header.

###### Example

Shows how to use Boost.Polygon rectangle_data within Boost.Geometry

    #include <iostream>
    #include <boost/geometry.hpp>
    #include <boost/geometry/geometries/adapted/boost_polygon.hpp>

    int main()
    {
        typedef boost::polygon::rectangle_data<int> rect;

        rect b = boost::polygon::construct<rect>(1, 2, 3, 4);

        std::cout << "Area (using Boost.Geometry): "
            << boost::geometry::area(b) << std::endl;
        std::cout << "Area (using Boost.Polygon): "
            << boost::polygon::area(b) << std::endl;

        return 0;
    }

Output:

    Area (using Boost.Geometry): 4
    Area (using Boost.Polygon): 4
