NAME
       tiffcmp - compare two TIFF files

SYNOPSIS
       tiffcmp [ options ] file1.tif file2.tif

DESCRIPTION
       Tiffcmp	compares  the  tags and data in two files created according to
       the Tagged Image File Format, Revision 6.0.  The schemes used for  com‐
       pressing	 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 differ‐
       ence.

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

       -t     Ignore any differences in directory tags.

BUGS
       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	 TIFFReadScan‐
       line() function is used.	 A error will be reported for tiled files.

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