[Insight-users] Class doesn't pass the data

[soheilghafurian]

when I write the same think this way it works. Does anyone have any idea, why
it doesn't work the first way? Is it related to itk smart pointers?

Header:

class C_GetDicomDifference
{
	typedef itk::SubtractImageFilter < DicomImageType , DicomImageType ,
DicomImageType > DifferenceFilterType ;

	DifferenceFilterType::Pointer DifferenceFilter ; 
	

public:
	C_GetDicomDifference ( DicomImageType::Pointer , DicomImageType::Pointer )
;

	DicomImageType::Pointer Difference;
};

source:

#include "GetDicomDifference.h"

C_GetDicomDifference::C_GetDicomDifference ( DicomImageType::Pointer Dicom1, 
											DicomImageType::Pointer Dicom2 ) 
{
	DifferenceFilter = DifferenceFilterType::New() ;
	DifferenceFilter->SetInput1 ( Dicom1 ) ;
	DifferenceFilter->SetInput2 ( Dicom2 ) ;

	Difference = DifferenceFilter->GetOutput()  ;
}
