<p><i>Tiffcmp</i> compares the tags and data in two files

52 |
created according to the Tagged Image File Format, Revision
|
|

53 |
6.0. The schemes used for compressing data in each file are

|
54 |
immaterial when data are compared−data are compared on
|
|
|
55 |
a scanline-by-scanline basis after decompression. Most

directory tags are checked; notable exceptions are:

<i>GrayResponseCurve</i>, <i>ColorResponseCurve</i>, and

the <i>BitsPerSample</i>, <i>SamplesPerPixel</i>, or
|
|
|
60 |
<i>ImageWidth</i> values are not equal. By default,
