Detailed Description

template<typename T, int N>
class lsst.afw.geom::Point< T, N >

Constructor & Destructor Documentation

template<typename T, int N>

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

inlineexplicit

Construct a Point with all elements set to the same scalar value.

Definition at line 156 of file Point.h.

: Super(val) {}

template<typename T, int N>

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>

lsst.afw.geom::Point< T, N >::Point ( EigenVector const &  vector )

inlineexplicit

Construct a Point from an Eigen vector.

Definition at line 169 of file Point.h.

: Super(vector) {}

template<typename T, int N>

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

inlineexplicit

Explicit constructor from Extent.
