Member Data Documentation

template<typename T >

T(* npl::NDView< T >::castget) (void *ptr)

protected

Function pointer to the correct function for casting from the underlying type.

ptr	location in memory where the pixel is stored

Definition at line 303 of file accessors.h.

template<typename T >

void(* npl::NDView< T >::castset) (void *ptr, const T &v)
