[ITK-users] question about wiki example ResampleDICOM

[Arnaud Gelas]

Hi Nick,

I can confirm that with the example I get a difference of -1024 (+/- 1) in
between the input and the output, using the ShiftScaleImage part...
While without this part of code the difference is (+/-1)

I would like to make sure this is the expected behaviour!?
