[vtkusers] shrinking StructuredPoints

[Kyle Johnson]

Hi,

I am trying to shrink data read from a vtk file.  I tried to use
vtkImageShrink3D as well as ImageResample but they do not shrink it
enough.  By that, I mean that the data gets shrunk but the dimensions
stay the same.  Is there an efficient way to shrink the dimensions and
the data at the same time?  When I set the dimensions (originally the
data is 256x256x128; set to 128x128x128), whenever I update the reader
the dimensions change back.

Thanks,
Kyle
