literal>TIFFSetField</

in the current directory associated with the open TIFF file. A pseudo-tag
is a parameter that is used to control the operation of the TIFF library but
whose value is not read or written to the underlying file.</
para>
<
para>To set the value of a field, the file must have been previously opened
for writing with <
literal>TIFFOpen(3tiff)</
literal>. Pseudo-tags can be set whether
the file was opened for reading or writing.</
para>
<
para>The field is identified by <
literal>tag</
literal>, one of the values
defined in the include file <
filename>
tiff.h</
filename> (see also the table
below). The actual value is specified using a variable argument list as prescribed
by the <

varargs(3)</

<

a pointer to a variable argument list. <
