To obtain the best answers quickly when you want help in
processing datasets -- extracting, transforming, filtering,
you should:
1. Post representative samples of your data (i.e. data that
should "succeed" and data that should "fail")
2. Post what you expect the results to be, instead of trying
only to describe them. Be clear about how the results are to be
obtained, e.g. "add field 2 in file1 to field 3 from file2"
3. Post what you have attempted to do so far.
4. Place the data and expected output within CODE tags, so that
they are more easily readable.
Special cases, exceptions, etc., are very important to include
in the samples.
cheers, drl

tiffcmp
TIFFCMP(1) General Commands Manual TIFFCMP(1)
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.
