Hi, everyone,

I have a problem with vtkImageDilateErode3D filter. For some reasons it
doesn't return the processed volume.
Here is the information about the input volume:

Here is the code:
            /
            connector->GetOutput()->Print(std::cout); //before
            vtkSmartPointer<vtkImageDilateErode3D> dilateErode =
            vtkSmartPointer<vtkImageDilateErode3D>::New();
            dilateErode->SetInputData(connector->GetOutput());
            dilateErode->SetDilateValue(0);
            dilateErode->SetErodeValue(255);
            dilateErode->SetKernelSize(5, 5, 3);
            dilateErode->GetOutput()->Print(std::cout); //after/

Could you point me in the right direction?
