  51 <p><i>Tiffcmp</i> compares the tags and data in two files
  52 created according to the Tagged Image File Format, Revision
  53 6.0. The schemes used for compressing data in each file are
  54 immaterial when data are compared&minus;data are compared on
  55 a scanline-by-scanline basis after decompression. Most
  56 directory tags are checked; notable exceptions are:
  57 <i>GrayResponseCurve</i>, <i>ColorResponseCurve</i>, and
  58 <i>ColorMap</i> tags. Data will not be compared if any of
  59 the <i>BitsPerSample</i>, <i>SamplesPerPixel</i>, or
  60 <i>ImageWidth</i> values are not equal. By default,
  61 <i>tiffcmp</i> will terminate if it encounters any
  62 difference.</p>
