lsst::geom::Point< T, N >::Point ( Point< U, N > const &  other )

explicitnoexcept

Explicit converting constructor.

Converting from floating point to integer rounds to the nearest integer instead of truncating. This ensures that a floating-point pixel coordinate converts to the coordinate of the pixel it lies on (assuming the floating point origin is the center of the first pixel).
