boost boost get_rectangles

boost库中没有直接提供获取矩形的函数。如果您想要获取一个矩形的坐标和尺寸，可以使用boost.geometry库来进行处理。以下是一个示例代码，展示了如何使用boost.geometry库来获取矩形的坐标和尺寸：

#include <iostream>
#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point.hpp>
#include <boost/geometry/geometries/box.hpp>

int main()
{
    typedef boost::geometry::model::d2::point_xy<double> point_type;
    typedef boost::geometry::model::box<point_type> box_type;

    box_type rectangle(point_type(0, 0), point_type(10, 5));

    double x_min = boost::geometry::get<boost::geometry::min_corner, 0>(rectangle);
    double y_min = boost::geometry::get<boost::geometry::min_corner, 1>(rectangle);
    double x_max = boost::geometry::get<boost::geometry::max_corner, 0>(rectangle);
    double y_max = boost::geometry::get<boost::geometry::max_corner, 1>(rectangle);

    std::cout << "Rectangle coordinates: (" << x_min << ", " << y_min << ") - (" << x_max << ", " << y_max << ")" << std::endl;
    std::cout << "Rectangle width: " << x_max - x_min << std::endl;
    std::cout << "Rectangle height: " << y_max - y_min << std::endl;

    return 0;
}
