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 com-
       pared if any of the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal.	By default, tiffcmp will terminate if  it  encoun-
       ters any difference.

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 TIFFReadScanline() 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.
