para>The following routines are provided for client-control of the I/O buffers
10139N/Aused by the library. Applications need never use these routines. The routines
10139N/Aare provided only for “intelligent clients” that wish to optimize
10139N/Amemory usage
and/
or eliminate potential copy operations that can occur when
10139N/Aworking with images that have data stored without compression.</
