Hi Invisible Human,

  Could you please send me such DICOM produced by ITK-GDCM that cannot
be reread.

Thanks !

Compression is needed only to transport the images over a slow wan network i.e. i want to compress an image or image series, transport it and then uncompress it to its original format.  Simple zip or rar compression has about a 50% gain but i am hoping that with JPEG2000, it will be around 70%.

The problem with GDCMImageIO is that when the input is a dicom series or image, the output is correct but when the input is raw volumetric data, the GDCMImageIO output is garbage and in fact the program crashes.
