<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> | |
