[vtkusers] How read stack of TIF images

[Carl Trapani]

Hi All,

I'm trying to display a stack of 10 RGB cross section images as a 
volume. The images are in-situ hybridization cross sections of the mouse 
cerebellum that have been manually segmented and thresholded. You can 
see them here:

The files are TIF or PNG or I can convert to some other standard format.

1) vtkVolume16Reader doesn't seem appropriate, is it? Are there any 
other vtkVolumeReader sub-classes that I might use?
2) What format are the images in VTKData/Data/headsq/quarter?
3) Any suggestions on classes to use or example to look at?

I'm using VTK 5.2.

Thanks,
Carl
