31 * \brief *very* internal class . Shouldn't appear here !
32 * Utility class for summerizing the informations of a JPEG
33 * fragment of an "Encapsulated JPEG Compressed Image".
34 * This information is a mix of:
35 * - the fragment offset
36 * - the fragment length
38 * Each instance of this class (they can be as many instances for
39 * a given Document as they are JPEG fragments and they are
40 * collected in a \ref JPEGFragmentsInfo )
