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.
