How do I pass the ownership from a filter? Is this enough?

typedef itk::ImageDuplicator<ImageType> DuplicatorType;
DuplicatorType::Pointer duplicatorFilter = DuplicatorType::New();
duplicatorFilter->SetInputImage ( filter->GetOutput());
duplicatorFilter->Update();
ImageType::Pointer pImage = duplicatorFilter->GetOutput();

Or should I also allocate first  ImageType::Pointer pImage = ImageType::New(); ?

Thank you so much, never used this filter!

As I isolated it from my other code, the whole pipeline works fine, so
I don't seem to correctly use the smart pointers.

Thanks,
