.SH NAME

|

|
.SH SYNOPSIS
|
||
|
|
.B tiffcmp
|
||
|
|
[
|
||
|
|
.I options
|

.SH DESCRIPTION
|
||
|
|
.I 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:
|
||
|
|
.IR GrayResponseCurve ,
|
||
|
|
.IR ColorResponseCurve ,
|
||
|
|
and
|
||
|
|
.IR ColorMap
|
||
|
|
tags.
|
||
|
|
Data will not be compared if any of the
|
||
|
|
.IR BitsPerSample ,
|
||
|
|
.IR SamplesPerPixel ,
|
||
|
|
or
|
||
|
|
.I ImageWidth
|
||
|
|
values are not equal.
|
||
|
|
By default,
|
||
|
|
.I tiffcmp
|
||
|
|
will terminate if it encounters any difference.
|
||
|
|
.SH OPTIONS
|
||
|
|
.TP

||
|
|
