Description

In DICOM PS 3.5-2011 Section A.4.2: "Each frame shall be encoded in one and only one Fragment."

However, the current implementation ignores this. A warning during compression and decompression would be appropriate. In fact, the creation of such erroneous files should be prevented in the first place.

The command line tool "dcmcrle" has a small note saying that the --fragment-size option is "(non-standard)". However, the underlying class DcmRLEEncoderRegistration is silent on this violation of the DICOM standard.
