<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><i>Tiffcmp</i>
compares the tags and data in two files created according to
the Tagged Image File Format, Revision 6.0. The schemes used
for compressing data in each file are immaterial when data
are compared−data are compared on a
scanline-by-scanline basis after decompression. Most
directory tags are checked; notable exceptions are:
<i>GrayResponseCurve</i>, <i>ColorResponseCurve</i>, and
<i>ColorMap</i> tags. Data will not be compared if any of
the <i>BitsPerSample</i>, <i>SamplesPerPixel</i>, or
<i>ImageWidth</i> values are not equal. By default,
<i>tiffcmp</i> will terminate if it encounters any
difference.</p>

<h2>BUGS
<a name="BUGS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Tags that are
not recognized by the library are not compared; they may
also generate spurious diagnostics.</p>
<p style="margin-left:11%; margin-top: 1em">The image data
of tiled files is not compared, since the
<i>TIFFReadScanline()</i> function is used. An error will be
reported for tiled files.</p>
<p style="margin-left:11%; margin-top: 1em">The pixel
and/or sample number reported in differences may be off in
some exotic cases.</p>
