<p><i>Tiffcmp</i> 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: | |
<i>GrayResponseCurve</i>, <i>ColorResponseCurve</i>, and | |
<i>ColorMap</i> tags. Data will not be compared if any of | |
the <i>BitsPerSample</i>, <i>SamplesPerPixel</i>, or | |
<i>ImageWidth</i> values are not equal. By default, | |
<i>tiffcmp</i> will terminate if it encounters any | |
difference.</p> | |

<p>The image data of tiled files is not compared, since the | |
