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.
