n Reference Zone: A defined static zone. It is used to locate the text or barcode. If the Reference
Zone moves on the page all fields that reference it are adjusted to accommodate for the movement.
n ShowValue: The True/False field specifies if the field will be displayed on the validation screen.
n Filter: Allows the entry of a regular expression or database lookup to validate data that was OCR’d
from a zone. A regular expression filter sample is provided in the Step by Step Invoice Example
section of this guide.
l Regular Expression: For details see pages like www.regular-expressions.info for
information on building regular expressions.
l ODBC query: these filters are used by the system to connect to a database and run simple
queries. If the recognized text of the zone is included in the result list of the query, then the
filter criterion is considered met; if not, a Filter failed error message is displayed. To use it,
you have to enter the following data:
n Connection String: SQL connection string, used to connect to the database. For example, an
MSSQLServer 2008 connection string has the following format: Driver={SQL Server Native
Client 10.0}; Server=<your IP address or DNS>; Database=<your database name>;
Uid=<your user account>; Pwd=<your password>;
n Query: enter an SQLquery, which, when run, will compile the value list used to check the
recognition results. The query may contain a ##value## constant, which denotes the value
recognized for the zone. For example:
SELECT Value FROM dbo.CustomValues
WHERE Id <> ##value##
n Test: Displays the results of the query prior to saving the filter settings.
Zone Properties can be viewed in categorized or alphabetical order.
15.3- Testing Templates
The template design tool lets you open a sample form and visually verify the results without having to scan a
page or run the ShareScan client. After a successful test we recommend that you also do actual scanner tests.
To test a template, follow the steps below:
1. Click Test Template in the editor. The Template Tester window is displayed.
2. Select the Template library you want to test via the dropdown list.
3. Select the image on which you want to test the process by clicking the ... button next to the Image
file field.
4. Optionally, you can set Image Cleanup settings via the Image modification settings pane by
clicking the Add button and selecting the relevant cleanup operation (for example, Autorotate,
Deskew, and so forth).
5. Click Recognize to start the test.
