[vtkusers] How to read a tiff file into volume

[James Carroll]

Using the SetFilePrefix method is necessary, VTK can't read tiff volumes
(the ITK does read tiff volumes, so some people will read the multi-tiff
into ITK, and then convert to VTK.)

If you need to separate out the individual levels of your stack
you can use the tiffsplit utility from libtiff.

(the link might just have the source, and not binaries...)

If you have a series of tiff tiles, then use the SetFilePrefix method of

vtkImageReader2 (superclass of vtkTIFFReader) instead of SetFileName.
