Changing Zone Properties
You can set certain properties for zones to customize how each zone will
be treated during OCR. The Zone Properties dialog box contains settings
for
zone type
and
zone content
.
Zone Type
Every zone on a page has a zone type setting. You can select the
following zone types:
•
Single-column zone
for text zones that contain a single column
•
Multiple-column zone
for text zones that contain multiple columns
•
Table zone
for text zones that contain text in tabbed columns
•
Mixed zone
for text zones that contain a mixture of column
layouts
•
Graphic zone
for photos, drawings, and areas of text that you want
to retain as a graphic. The letter
G
appears within graphic zones.
OCR is not performed on graphic zones.
Zone Content
All text zones on a page also have a zone content setting. This specifies
the characters OmniPage Pro looks for within a zone during OCR. You
can select
Alphanumeric
or
Numeric
as the zone content setting. The letter
A
appears within an alphanumeric zone and the letter
N
appears within
a numeric zone.
For example, if a particular zone only contains numbers and
mathematical signs, you can specify the contents of that zone to be
Numeric
. OmniPage Pro will only look for numeric characters in that
zone during recognition.
OmniPage Pro assigns zone properties to each zone when it creates
zones automatically. You do not need to change the zone properties
unless you want to modify the way zones will be treated during OCR.
