Hi,
thanks Kent, I can now answer my own question, as your message prompted me
to have another, deeper look at the VTk books. Actually in "The Visualization
Toolkit", page 144, is written "..in the direction of increasing x, then y,
then z", which I hadn't spotted earlier.
Thanks,
Marc
NB: a suggestion for the authors of the documentation: maybe it would be useful
to add this also to the user guide, in particular
to the file formats section or to the chapter on ImageData?
