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
       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.

OPTIONS
       -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.

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
       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.
