The value can be either an integer number, or "ALL_CPUS". If OPJ_NUM_THREADS is set and this function is called, this function will override the behaviour of the environment variable.</p>

PLT=YES/NO. Defaults to NO. If set to YES, PLT marker segments, indicating the length of each packet in the tile-part header, will be written. Since 2.4.0 </li>

<li>

GUARD_BITS=value. Number of guard bits in [0,7] range. Default value is 2. 1 may be used sometimes (like in SMPTE DCP Bv2.1 Application Profile for 2K images). Since 2.5.0 </li>
