Arnaud, Luis,

That enum lets you check the pixel type manually (in a loop, comparing
the GetComponentType() result to all of the entires in the enum, but
can you do something more like this?

  const ScalarPixelType pixelType = imageIO->GetComponentType();
  const int numberOfComponents = imageIO->GetNumberOfComponents();

  typedef itk::VectorImage<pixelType, 2> ImageType;
  image->SetNumberOfComponentsPerPixel(numberOfComponents);

Of course it is complaining because the enum value in pixelType is not
equivalent to the actual word 'float' which would need to be passed as
the template parameter.
