I'm sorry if I'm abit thick, but this doesn't work.
I tried to read documents and old mailing list entries, but I don't find an answer, just in the past someone with a similar problem wound up using CropImageFilter instead.
Can someone clarify why this doesn't work? I'd specifically LIKE to maintain the origin of the region as the origin of the original image.

But the output image should be getting created (returned) by the filter?So how can it not be consistent???
Or what's going on?
Especially since it worked fine in a previous program with 2d data.
I tried a bit harder and used the object interface, and compare 2d and 3d, and try to set the collapse strategy..
And it works in 2d but not in 3d, I really can't see why.
