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 dif
ference.
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 com
pared; they may also generate spurious diagnostics.
