pydicom does not yet handle pixel compression schemes, so if you need to 
manipulate pixels in such dicom files using pydicom, then you should first pass 
the files through a decompression program. This could be done, for example, 
with command-line tools in dcmtk.

Closing the issue as not handling compressed pixel data is standard behaviour 
in current pydicom.
