<a name="DESCRIPTION"></a>

<p style="margin-left:11%; margin-top: 1em"><b>TIFFFieldReadCount</b>
returns the number of values available to be read from the
specified TIFF field; that is, the number of arguments that
should be supplied to <b>TIFFGetField</b>. For most field
types this is a small positive integer, typically 1 or 2,
but there are some special values: <b><br>
TIFF_VARIABLE</b> indicates that a variable number of values
is possible; then, a <b>uint16</b> <i>count</i> argument and
a pointer <i>data</i> argument must be supplied to
<b>TIFFGetField</b>. <b><br>
TIFF_VARIABLE2</b> is the same as <b>TIFF_VARIABLE</b>
except that the <i>count</i> argument must have type
<b>uint32</b>. <b><br>
TIFF_SPP</b> indicates that the number of arguments is equal
to the image&rsquo;s number of samples per pixel.</p>
