I think there's a new bug in vtkExtractVOI in VTK-4.2.2, which was not
present in VTK-4.1. The filter seems to screw up the origin of the
dataset when using a sample-rate > 1.
The attached python script illustrates the problem: On running the
script, the Bounds and Origin of the output of vtkExtractVOI() are
printed. The dataset origin should coincide with the lower values of the
dataset bounds. With VTK-4.2.2, the Origin is clearly incorrect (looks
like a sign-problem). Running the script on VTK-4.1 gives the expected,
Can someone else verify this effect. What's the procedure for
