30
31compares the tags and data in two files created according
32to the Tagged Image File Format, Revision 6.0.
33The schemes used for compressing data in each file
34are immaterial when data are compared-data are compared on
35a scanline-by-scanline basis after decompression.
36Most directory tags are checked; notable exceptions are:
37<I>GrayResponseCurve</I>,
38
39<I>ColorResponseCurve</I>,
40
41and
42<I>ColorMap</I>
43
44tags.
45Data will not be compared if any of the
46<I>BitsPerSample</I>,
47
48<I>SamplesPerPixel</I>,
49
50or
51<I>ImageWidth</I>
52
53values are not equal.
54By default,
55<I>tiffcmp</I>
56
57will terminate if it encounters any difference.
