[vtkusers] imageSliceMapper->GetSliceNumber() problem

[José M. Rodriguez Bacallao]

ohh, I got it, the think is that I am only using vtkImageResliceMapper
because of its capability to manage big images very well, no to do
oblique reformats, just orthogonal ones. I understand what you say
about calculating the distance between planes, but, there is a ready
made example?
