<h2>DESCRIPTION</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>
