[Insight-users] Polymorphism while using Registration Framework

[Stefan König]

Hmm ok, this was an error by taking the wrong objects.

but there is another one remaining:

Error	1	error C2664:
'itk::ImageRegistrationMethod<TFixedImage,TMovingImage>::SetTransform'
: cannot convert parameter 1 from
'itk::Transform<TScalarType,NInputDimensions> *' to
'itk::Transform<TScalarType,NInputDimensions,NOutputDimensions> *'

	m_pRegistrator->SetTransform(trans->getTransformation());

my return value is
        itk::Transform<double, Dimension>::Pointer

and the SetTransform inside the documentation of
itkImageRegistrationMethod.h tells me, that the parameter should be a
"	TransformType *  	_arg	" which is linked to itk::Transform.

whats wrong here
