Yes, that is what I needed!

I find it quite confusing that SetSpacing does not work as I (new
user) expected.
I don't thing this is gdcm issue, it has nothing to do with dicom. Of
course it would be better if the reader had proper spacing at the
beginning.

This question was stated several times on vtk forum and I did not
found the wright answer.
Maybe this case should be stretch out on some FAQ?


Thank you all for help.
