<p><i>tiffcrop</i> combines one or more files created
|
|
|
|
|
according to the Tag Image File Format, Revision 6.0 into a
|
|
|
|
|
single <small>TIFF</small> file. The output file may be
|
|
|
|
|
compressed using a different algorithm than the input files.
|
|
|
|
|
<i>tiffcrop</i> is most often used to extract portions of an
|
|
|
|
|
image for processing with bar code recognizer or OCR
|
|
|
|
|
software when that software cannot restrict the region of
|
|
|
|
|
interest to a specific portion of the image or to improve
|
|
|
|
|
efficiency when the regions of interest must be rotated.</p>
|
|
|
|
|
<!-- INDENTATION -->
|
|
|
|
|
<p>By default, <i>tiffcrop</i> will copy all the understood
|
|
|
|
|
tags in a <small>TIFF</small> directory of an input file to
|
|
|
|
|
the associated directory in the output file.</p>
|
|
|
|
|
<!-- INDENTATION -->
|
|
|
|
|
<p><i>tiffcrop</i> can be used to reorganize the storage
|
|
|
|
|
characteristics of data in a file, and it will alter or
|
|
|
|
|
convert the image data content as specified at the same
|
|
|
|
|
time, unlike tiffcp.</p>
|
|
|

<!-- INDENTATION -->
|
