The LargestPossibleRegion can have an index other than (0,0,0). But there
are only a few instances where this occurs. PadImageFilter is one.
There was a bug in the ChangeInformationImageFilter when using a reference
image.
I checked in a fix to the CVS repository. The filter should work for you
now.
Thanks for sending your test code. It was a big help.
Let me know if you any additional problems.
