00025  * to register the format into the IM core library. \n

00049     Comments:
00050       We read code stream syntax and JP2, but we write always as JP2.
00051       Used definitions EXCLUDE_JPG_SUPPORT,EXCLUDE_MIF_SUPPORT,
00052                        EXCLUDE_PNM_SUPPORT,EXCLUDE_RAS_SUPPORT,
00053                        EXCLUDE_BMP_SUPPORT,EXCLUDE_PGX_SUPPORT
00054       Changed jas_config.h to match our needs.
00055       New file jas_binfile.c
00056       Changed jas_stream.c to export jas_stream_create and jas_stream_initbuf.
00057       Changed jp2_dec.c and jpc_cs.c to remove "uint" and "ulong" usage.
