voronoi warning: conversion from '__int64' to 'const int' at insert(const Segment& segment, VB* vb)

[yoavmil]

My datatype is int64, and for some reason Boost is converting it to int. struct Point { int64 X, Y; }

polygon\voronoi.hpp(68,8): warning C4244: 'argument': conversion from '__int64' to 'const int', possible loss of data

template <typename Segment, typename VB>
typename enable_if<
  typename gtl_if<
    typename is_segment_concept<
      typename geometry_concept<Segment>::type
    >::type
  >::type,
  std::size_t
>::type insert(const Segment& segment, VB* vb) {
  return vb->insert_segment(
      x(low(segment)), y(low(segment)), // this is where the warning comes from
      x(high(segment)), y(high(segment)));
}

Maybe I'm doing something wrong, please advise, and maybe it is similar to this.

By default the vertices are int32. If you want the full scale of 64bit int, then you have to provide your own traits

Actually I am using traits and I'm following the tutorial. Please take a glance at my code.

struct Point { int64 X, Y; }

namespace boost {
namespace polygon {

template <>
struct geometry_concept<Point> {
    typedef point_concept type;
};

template <>
struct point_traits<Point> {
    typedef int64 coordinate_type;

    static inline coordinate_type get(
        const Point& point, orientation_2d orient) {
        return (orient == HORIZONTAL) ? point.X : point.Y;
    }
};

template <>
struct geometry_concept<BoostSegment> {
    typedef segment_concept type;
};

template <>
struct segment_traits<BoostSegment> {
    typedef Point point_type;

    static inline point_type get(const BoostSegment& segment, direction_1d dir) {
        return dir.to_int() ? segment.first : segment.second;
    }
};

}  // polygon
}  // boost
