Assign two coordinates to a geometry (usually a 2D point)
template<typename Geometry, typename Type> void assign_values(Geometry & geometry, Type const & c1, Type const & c2)
| Type | Concept | Name | Description | 
|---|---|---|---|
| Geometry & | Any type fulfilling a Geometry Concept | geometry | A model of the specified concept | 
| Type const & | numerical type (int, double, ttmath, ...) to specify the coordinates | c1 | First coordinate (usually x-coordinate) | 
| Type const & | numerical type (int, double, ttmath, ...) to specify the coordinates | c2 | Second coordinate (usually y-coordinate) | 
Either
            #include <boost/geometry.hpp>
          
Or
            #include <boost/geometry/algorithms/assign.hpp>
          
Shows the usage of assign to set point coordinates
#include <iostream> #include <iomanip> #include <boost/geometry.hpp> #include <boost/geometry/geometries/point_xy.hpp> int main() { using boost::geometry::assign_values; boost::geometry::model::d2::point_xy<double> p1; assign_values(p1, 1.2345, 2.3456); std::cout << std::setprecision(20) << boost::geometry::dsv(p1) << std::endl; return 0; }
Output:
(1.2344999999999999, 2.3456000000000001) (1.2345, 2.3456)
