[Insight-users] VTK to ITK

Hi Marta, 

You need to assign the connector to an smart pointer so it keeps a
reference. Otherwise the newly created object is automatically destroyed

Try

VtkToItkConnectorType::Pointer filter = VtkToItkConnectorType::New();

And then use filter the same way. 
Hope that helps

Iván

Hi,

I'm having trouble converting a SLC vtk volume to an itk image. I am using
the itk::VTKImageToImageFilter but whenever I try to set the input to the
filter I get a segmentation fault (the code is below)... would anyone have
any ideas?

Thanks,
Marta


// read SLC file
 vtkSLCReader *slcReader = vtkSLCReader::New();
slcReader->SetFileName(filename);
slcReader->Update();

vtkImageData *volume = slcReader->GetOutput();
volume->PrintSelf(std::cout, 4);

typedef  itk::Image<short,3>  ImageType;
typedef  itk::VTKImageToImageFilter<ImageType>    VtkToItkConnectorType;

VtkToItkConnectorType *filter = VtkToItkConnectorType::New();
filter->SetInput(volume);  /****************seg faults
here**********************/
filter->Update();

ImageType::ConstPointer itkImage = filter->GetOutput(); .....
