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.

       -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 TIFFReadScan-
       line() 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.
