lsst::afw::geom::Point< T, N >::Point ( T val = static_cast<T>(0) )

template<typename U >

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

explicit

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).

template<typename T, int N = 2>

Construct a Point from an Eigen vector.
