[vtkusers] Error in vtkImageChangeInformation

[David Gobbi]

Hi Matthias,

When I tried your example with the 'headsqr' image from
the vtk example data it worked fine.  The problem might
be with the extent you set in the data reader, if your
images are 512x512x120 then you should set up the
reader like this:

reader.SetDataExtent(0,511,0,511,1,120)

I'll take a look through vtkImageChangeInformation and
try to figure out why it was reporting the error, however.
