<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFSetField</i></b>
sets the value of a field or pseudo-tag in the current
directory associated with the open <small>TIFF</small> file
<i>tif</i>. (A <i>pseudo-tag</i> is a parameter that is used
to control the operation of the <small>TIFF</small> library
but whose value is not read or written to the underlying
file.) To set the value of a field the file must have been
previously opened for writing with <i>TIFFOpen</i>(3TIFF);
pseudo-tags can be set whether the file was opened for
reading or writing. The field is identified by <i>tag</i>,
one of the values defined in the include file <b>tiff.h</b>
(see also the table below). The actual value is specified
using a variable argument list, as prescribed by the
<i>stdarg</i>(3) interface (or, on some machines, the
<i>varargs</i>(3) interface.)</p>
<p style="margin-left:11%; margin-top: 1em"><i>TIFFVSetField</i>
is functionally equivalent to <i>TIFFSetField</i> except
that it takes a pointer to a variable argument list.
<i>TIFFVSetField</i> is useful for writing routines that are
layered on top of the functionality provided by
<i>TIFFSetField</i>.</p>
<p style="margin-left:11%; margin-top: 1em">The tags
understood by <i>libtiff</i>, the number of parameter
values, and the expected types for the parameter values are
shown below. The data types are: <i>char*</i> is
null-terminated string and corresponds to the
<small>ASCII</small> data type; <i>uint16</i> is an unsigned
16-bit value; <i>uint32</i> is an unsigned 32-bit value;
<i>uint16*</i> is an array of unsigned 16-bit values.
<i>void*</i> is an array of data values of unspecified
type.</p>
<p style="margin-left:11%; margin-top: 1em">Consult the
<small>TIFF</small> specification for information on the
meaning of each tag.</p>
