tiffcmp - compare two TIFF files

       Tags  that  are  not  recognized  by  the  library  are  not  compared;  they  may also generate spurious
       diagnostics.

       The image data of tiled files is not compared, since the TIFFReadScanline() function is used.   An  error
       will be reported for tiled files.

       The pixel and/or sample number reported in differences may be off in some exotic cases.

Tiffcmp  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: GrayResponseCurve, ColorResponseCurve, and ColorMap tags.  Data will not
       be compared if any of the BitsPerSample,  SamplesPerPixel,  or  ImageWidth  values  are  not  equal.   By
       default, tiffcmp will terminate if it encounters any difference.

-l     List each byte of image data that differs between the files.

       -znumber
              List specified number of image data bytes that differs between the files.

       -t     Ignore any differences in directory tags.
