Hi, John :

My code is

// Map the image through the lookup table
    vtkSmartPointer<vtkImageMapToColors> color =
vtkSmartPointer<vtkImageMapToColors>::New();
    color->SetLookupTable(table);
    color->SetInputConnection(reslice->GetOutputPort());

    m_imgDataOnImagePlaneX->DeepCopy(color->GetOutput());

These code are in a class member function, and m_imgDataOnImagePlaneX is a
class member variable. I used vtkImageViewer2 to display the image data from
m_imgDataOnImagePlaneX, but nothing is on the VTK window. However, when I
used vtkImageViewer2 to display the image data from color->GetOutput() in
that class member function, that is ok. I don't know why.
