Customizing Zones
72 Chapter 5
Zone Type
Every zone on a page has a zone-type setting. You can select the
following zone types:
•
Single-column text zone
for text zones that contain a single column
•
Multiple-column text zone
for text zones that contain multiple
columns
•
Table zo ne
for text or numeric zones that contain data in rows and
columns
•
Auto-detect zone
for the automatic detection of zone-content type
(not usually recommended)
•
Graphic zone
for photos, drawings, and areas of text that you want
to retain as a graphic
•
Reverse-text zone
for single columns of light text on dark
background
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.
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 a zone type and Alphanumeric contents to each
zone when it creates zones automatically. This is true for all zones
recognized automatically, except graphic-content zones. You do not
need to change the zone properties unless you want to modify the way
zones will be treated during OCR.
To change the properties of a zone:
1 Select the zone you want to modify by clicking it.
You can Shift-click to select multiple zones. Selected zones are
shaded.
