- <p>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>
- <!-- INDENTATION -->
- <p><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>
- <!-- INDENTATION -->
- <p><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>
