Filtering slices

[Mark Huenken]

Hello everybody,

a vtkBMPReader reads a run of images (SetFilePrefix, SetFilePattern).
There is one visualization pipeline for each slice. The first filter
that I add to the pipeline should limit the whole run to the one
specific slice as follows:

vtkImageCast cast = new vtkImageCast();
cast.SetInput(reader.GetOutput());
vtkImageCache cache = cast.GetOutput();
cache.SetWholeExtent(...,...,...,...,slice,slice); 
cache.UpdateImageInformation();

But what happens is that every visualization pipeline connected
to a viewport shows slice no. 0 instead of a different slice.

Am I missing something?

Any help would be appreciated 

Mark

P.S. I'm using vtk 2.2 and the Java wrapper
