31 * \brief Utility class for gathering the informations of the collection
32 * of JPEG fragment[s] (see JPEGFragment) when handling
33 * "Encapsulated JPEG Compressed Images".
34 * The informations on each frame are obtained during the pixel parsing
35 * of a gdcm::File (refer to File::ComputeJPEGFragmentInfo() ).
36 * They shall be used when (if necessary) decoding the fragments.
38 * This class is simply a stl list<> of JPEGFragment.
