Single column, no table
Choose this setting if your pages contain only one column of text and no
table. Business letters or pages from a book are normally like this. Choose
it also for a page with words or numbers arranged in columns if you do
not want these placed in a table or decolumnized or treated as separate
columns. Graphics may be detected.
Multiple columns, no table
Choose this if some of your pages contain text in columns and you want
this decolumnized or kept in separate columns, similar to the original
layout. Columns can be retained in the output document, either with
frames (if True Page is set) or without frames (if Retain Flowing Columns
is set). If tabular data is encountered, it is likely to be treated as flowing
text. Graphics may be detected.
Single column with table
Choose this if your page contains only one column of text and a table.
Auto-zoning will not look for columns but will try to find a table and
place it in a grid in the Text Editor.
Y
ou can later specify whether to
export it in a grid or as tab separated text columns. Graphics may be
detected.
Spreadsheet
Choose this if your whole page consists of a table which you want to
export to a spreadsheet program, or have treated as single table. No
flowing text or graphics zones will be detected.
Custom
Choose this for maximum control over auto-zoning.
Y
ou can prevent or
encourage the detection of columns, graphics and tables. Make your
settings in the Custom Layout panel of the Options dialog box.
Template
Choose a zone template file if you wish to have its zones and properties
applied to all acquired pages from now on. In manual processing the
template zones are also applied to the current page, replacing any existing
zones. Other zones are permitted in addition to template zones. For more
detail, see the section U

is active.
Y
ou cannot use this with a table type zone.
Reorder zones
Click this for the zone reordering tool. Then click in zones in the desired
reading order. For your order to be respected, choose ‘Use current zones
only’ and avoid having multiple-column or auto-detect zones types on
the page.
Zone properties

Each zone has a zone type. Zones containing text can also have a zone
contents setting: alphanumeric or numeric. The zone type and zone
contents together constitute the zone properties. Right-click in a zone for
a shortcut menu allowing you to change the zone’s properties. Select
multiple zones to change their properties in one move. The zone
properties button in the Image toolbar can be used for the same purpose.
The following types are available:
Single-column flowing text zone
Use this to have zone contents treated as flowing text, without columns
being found.
Multiple-column flowing text zone
Use this to have zone contents treated as flowing text. The program will try
to detect columns inside the zone. Text will be decolumnized or retained in
columns, depending on the Text Editor view. During recognition, a multi-
column zone may be replaced by separate zones for each column. To do
this, auto-zoning must run, which may also result in changed zone order.

Table zone
Use this to have the zone contents treated as a table. Table grids can be
automatically detected, or placed manually as described in the next
section. Table zones must be rectangular. The Text Editor displays the
table in an editable grid.
Y
ou can choose whether to export tables in grids
or in columns separated by tabs.
Auto-detect zone
Use this to let the program decide the zone type. To do this, auto-zoning
runs, which may also result in changed zone order on the page. After
recognition you can see the type that was applied. If you use an auto-
detect zone to cover a page area with varied contents, the program may
replace the auto-detect zone with a number of smaller zones.
Graphic zone
Use this to enclose a picture, diagram, drawing, signature or anything you
want transferred to the Text Editor as an embedded image, and not as
recognized text. A graphics zone has a green border. Embedded images
can be exported with the document to target applications supporting
graphics.
Ignore zone
Use this to define a page area you do not want in the Text Editor. Auto-
zoning will not place zones here. To exclude a given page area from many
pages (for example a header or page numbers), place ignore zones in a
template and select ‘Find zones in addition to template/current zones’ in
the Process panel of the Options dialog box.
Zone contents
This is available for zone types containing text. Alphanumeric contents
validates all characters needed for your language choice. Recognition
results from a numeric zone will contain only numbers and number-
related punctuation. No letters will be placed.
N
ote
Right-click outside a zone for a shortcut menu tailored for the whole
image. It allows you to zoom in or out or rotate the image. When an image is
rotated, all zones on it are deleted.

After automatic processing you may see table zones placed on a page.
They are denoted with a table zone icon in the top right corner of the
zone. To change a zone to or from a table zone, use its shortcut menu.
Y
ou can also draw a table type zone. If there is already a table zone on the
page, select it, then draw the new rectangular zone. It will inherit the
table type. Otherwise draw a rectangular zone and use its shortcut menu
to change it to a table type.
Y
ou draw or move table dividers to determine where gridlines will appear
when the table is placed in the Text Editor.
Y
ou can use the Add or
Subtract tools to enlarge or reduce a table zone, but it must remain
rectangular.
Y
ou can do this to discard unneeded columns or rows from a
table.
The five table handling tools on the Imaging toolbar become active if the
current page contains a table type zone. Use them as follows:
Move row or column dividers
Click the tool and move the cursor to the divider to be moved. It displays
a double-headed arrow. Drag the border as desired.
Y
ou cannot drag it
beyond its neighbor. Avoid placing dividers so they overlap one another
or cut through text. Press the Ctrl key as you drag a column divider, to
move it in the current row only.
Insert column dividers
Click the tool then click at the location in a table zone where you want to
place a column divider. Press the Ctrl key as you click to place the divider
in the current row only.
Insert row dividers
Click the tool then click at the location in a table zone where you want to
place a row divider. Avoid placing a divider on top of another one or so it
cuts through text.
Remove column or row dividers
Click the tool then click on a single divider you want to delete. Do this if
a divider is wrongly located, or if you want to change the appearance of
the table in the final document. For example, you can place two columns
of data in a single column by deleting the divider between the columns.

A template is a set of zones, their properties and reading order, stored in a
file. A zone template file can be loaded to have template zones used
during recognition. Load a template file in the Perform OCR drop-down
list or from the Tools menu.
When you load a template with the Manual OCR toolbar, its zones
appear immediately on the current page, replacing any already there.
Existing pages are not affected. The template zones are placed on all
further acquired pages until the template is unloaded.
Y
ou can modify the
template zones and add new zones before performing recognition.
When you load a template with the AutoOCR toolbar, it does not affect
the current or existing pages. The template zones are placed on all further
acquired pages until the template is unloaded. The Process panel of the
Options dialog box presents the option ‘Find zones in addition to
template/current zones’. If this is turned on during automatic processing,
auto-zoning will run on page areas outside the template zones.
How to save a zone template
Prepare zones on a page. Check their
locations, properties and reading order.
Click Zone Template File... in the Tools
menu. In the dialog box, select
[zones on
page]
and click Save.
How to modify a zone template
Load the template and acquire a suitable
image with manual processing. The template zones appear. Modify the
zones and/or properties as desired. Open the Zone Template File dialog
box. The current template is selected. Click Save and then Close.

How to unload a template
Select a non-template setting for layout description in the Perform OCR
drop-down list. The template zones are not removed from the current or
existing pages, but template zones will no longer be used for future
processing.
Y
ou can also open the Zone Template Files dialog box, select
[none]
and click the Set As Current button. In this case, the layout
description setting returns to Automatic.
How to replace one template with another
Select a different template in the Perform OCR drop-down list, or open
the Zone Template Files dialog box, select the desired template and click
the Set As Current button. When the AutoOCR toolbar is active, no
existing zones are changed and the new template is used for future
processing. When the Manual OCR toolbar is active, zones from the new
template are applied to the current page, replacing any existing zones.
How to delete a template file
Open the Zone Template Files dialog box. Select a template and click the
Delete button. Zones already placed by this template are not removed.

Templates accept ignore and auto-detect type zones. A template can
therefore be useful to define which parts of the page to read, and which
parts to ignore.
N
ote
Auto-detect type zones from a template may be replaced during
recognition by smaller ones; specific zone types will be assigned to these
zones. Multi-column zones may also be split into smaller single-column
zones, one for each detected column.

Templates and the additional auto-zoning feature are available in
Schedule OCR and Direct OCR, but not in the OCR Wizard.
