|
<p><i>TIFFGetField</i> returns the value of a tag or
|
|
pseudo-tag associated with the the current directory of 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.) The file
|
|
must have been previously opened with <i>TIFFOpen</i>(3T).
|
|
The tag 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 type and number of values returned is
|
|
dependent on the tag being requested. The programming
|
|
interface uses a variable argument list as prescribed by the
|
|
<i>stdarg</i>(3) interface. The returned values should only
|
|
be interpreted if <i>TIFFGetField</i> returns 1.</p>
|
|
<!-- INDENTATION -->
|
|
<p><i>TIFFVGetField</i> is functionally equivalent to
|
|
<i>TIFFGetField</i> except that it takes a pointer to a
|
|
variable argument list. <i>TIFFVGetField</i> is useful for
|
|
layering interfaces on top of the functionality provided by
|
|
<i>TIFFGetField</i>.</p>
|
|
<!-- INDENTATION -->
|
|
<p><i>TIFFGetFieldDefaulted</i> and
|
|
<i>TIFFVGetFieldDefaulted</i> are identical to
|
|
<i>TIFFGetField</i> and <i>TIFFVGetField</i>, except that if
|
|
a tag is not defined in the current directory and it has a
|
|
default value, then the default value is returned.</p>
|
|
<!-- INDENTATION -->
|
|
<p>The tags understood by <i>libtiff</i>, the number of
|
|
parameter values, and the types for the returned values are
|
|
shown below. The data types are specified as in C and
|
|
correspond to the types used to specify tag values to
|
|
<i>TIFFSetField</i>(3T). Remember that <i>TIFFGetField</i>
|
|
returns parameter values, so all the listed data types are
|
|
pointers to storage where values should be returned. Consult
|
|
the <small>TIFF</small> specification for information on the
|
|
meaning of each tag and their possible values.</p></td>
