     * 2. Temporary PNG (intermediate) file     (Activiz)
     * 3. Final DICOM file                      (SWIG)

     * Footnote:
     * this test originally used vtkBMPWriter / vtkBMPReader combination to store intermediate
     * image file, but BMP file are 24bits by default. Instead use PNG format which supports seems
     * to be closer to what was expected in this simple test.
