JPEG 2000 Profiles, see Table A.10 from 15444-1 (updated in various AMD) These values help chosing the RSIZ value for the J2K codestream.

The RSIZ value triggers various encoding options, as detailed in Table A.10. If OPJ_PROFILE_PART2 is chosen, it has to be combined with one or more extensions described hereunder. Example: rsiz = OPJ_PROFILE_PART2 | OPJ_EXTENSION_MCT; For broadcast profiles, the OPJ_PROFILE value has to be combined with the targeted mainlevel (3-0 LSB, value between 0 and 11): Example: rsiz = OPJ_PROFILE_BC_MULTI | 0x0005; (here mainlevel 5) For IMF profiles, the OPJ_PROFILE value has to be combined with the targeted mainlevel (3-0 LSB, value between 0 and 11) and sublevel (7-4 LSB, value between 0 and 9): Example: rsiz = OPJ_PROFILE_IMF_2K | 0x0040 | 0x0005; (here main 5 and sublevel 4)
