[Insight-users] casting of smart pointers

[Lodron, Gerald]

Hello,
 
Can anybody tell me what the conventional way is to cast a smartpointer?

typedef typename itk::InterpolateImageFunction<ImageType,double> InterpType; 
typedef typename itk::BSplineInterpolateImageFunction<ImageType, double, double> SplineInterpType; 


InterpType::Pointer interpolator;      

interpolator = SplineInterpType::New();     
dynamic_cast<SplineInterpType::Pointer>(interpolator)->SetSplineOrder(3);      //does not work


Best regards
