<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">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.</p>
<p style="margin-left:11%; margin-top: 1em"><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.</p>
<p style="margin-left:11%; margin-top: 1em"><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.</p>
