       tiffcmp - compare two TIFF files


       tiffcmp [ options ] file1.tif file2.tif


       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.

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

       -t     Ignore any differences in directory tags.


       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.
