The following routines are provided for client-control of
the I/O buffers used by the library. Applications need never
use these routines; they are provided only for ``intelligent
clients'' that wish to optimize memory usage and/or
eliminate potential copy operations that can occur when
working with images that have data stored without
compression.</td></table>

<i>TIFFReadBufferSetup</i> sets up the data buffer used to
read raw (encoded) data from a file. If the specified
pointer is <small>NULL</small> (zero), then a buffer of the
appropriate size is allocated. Otherwise the caller must
guarantee that the buffer is large enough to hold any
individual strip of raw data. <i>TIFFReadBufferSetup</i>
returns a non-zero value if the setup was successful and
zero otherwise.</td></table>

<i>TIFFWriteBufferSetup</i> sets up the data buffer used to
write raw (encoded) data to a file. If the specified
<i>size</i> is -1 then the buffer size is selected to hold a
complete tile or strip, or at least 8 kilobytes, whichever
is greater. If the specified <i>buffer</i> is
<small>NULL</small> (zero), then a buffer of the appropriate
size is dynamically allocated. <i>TIFFWriteBufferSetup</i>
returns a non-zero value if the setup was successful and
zero otherwise.</td></table>
