Readiris can deskew (straighten) documents and
rotate them by means of Page orientation
detection.
When your scanner generates black borders around
your documents, or when your documents contain
information that is partially cut from the page,
Readiris tends to create recognition zones on the
borders of the document, even though they do not
contain any useful content. In such cases it is
recommended to use the option Ignore Border
Zones.
