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.
