[Insight-users] Get the number of components per pixel without reading image

[Bill Lorensen]

Something like this:
      typedef itk::Image<unsigned char, 3> ImageType;
      itk::ImageFileReader<ImageType>::Pointer imageReader =
        itk::ImageFileReader<ImageType>::New();
      imageReader->SetFileName(fileName.c_str());
      imageReader->UpdateOutputInformation();

      pixelType = imageReader->GetImageIO()->GetPixelType();
      componentType = imageReader->GetImageIO()->GetComponentType();
