[vtk-developers] reproducible bug with vtkExtractVOI and vtkImageShiftScale

[Charl P. Botha]

Hi Lisa,

I've rebuilt with a fresh CVS update, and I can still reproduce the problem
with the examples I attached on my original mail about this matter.  So, can
it perhaps be that the vtkExtractVOI fix wasn't checked in?

Thanks for any help,
Charl
