[ITK] write BufferedRegion to file

[David Froger]

Dear all,

I'm reading in an HDF5 file a subregion of an image, and want to create a new
file with this subregion.

For example, the HDF5 file contains a vector image of dimensions (4,4,4,4),
and I read (2,2,2) pixels starting from pixel (1,1,1).

If I try to write the subregion in a new file, ITK try to write the largest
possible region, and it yields to a segfault.

I tried to use image->SetLargestPossibleRegion, image->SetRequestedRegion, 
image->SetBufferedRegion, writer->SetIORegion, RegionOfInterestImageFilter,
ExtractImageFilter without success.

Does someone has the solution?

Example files of what I'm trying to do are attached.

Thanks for reading.

Best regards,
David
