31 * \brief Utility class for summerizing the informations of a JPEG
32 * fragment of an "Encapsulated JPEG Compressed Image".
33 * This information is a mix of:
34 * - the fragment offset
35 * - the fragment length
37 * Each instance of this class (they can be as many instances for
38 * a given Document as they are JPEG fragments and they are
39 * collected in a \ref JPEGFragmentsInfo )
