[vtkusers] vtkImageColorViewer and slice orientation

[Lic. José M. Rodriguez Bacallao]

thanks, and another question:

I need to display the images in a dicom serie in several
configurations: just one image, 2 images side by side, 2x2 images and
so on. Which is the recommended way to display those configurations in
a render window, with several renderers or with several image actors?
