when you scan text from columns (like in magazines, etc.): if
you start scanning slightly on the previous word/column and end
scanning on the next one, the unwanted parts can be deleted.
Select this option if you want to ignore the rejected characters at
the beginning and at the end of the scan. If characters are
rejected within the lines, these will be kept for the output.
Also see: Additional options, Unknown Symbol.
Restore paragraph
You must indicate how to interpret hyphens occurring at the end
of a line. If you scan the lines "The new presi-" and "dent waved
from the balcony", the hyphen must obviously be dropped so as
to recompose the word "president" in the output: "The new
president waved from the balcony".
Select this option if you want to delete end hyphens.
Note: If hyphens are deleted, the suffixes (see below) will
automatically be deleted so that the words can be properly
recomposed.

The default prefix is: <None>.

You can have the IRISPen execute operations automatically in
the target application, either before or after the output result.
