FAQ: How is ICR enabled?

This forum post is maintained for legacy purposes and links may no longer be applicable. A separate post exists for v22:

By default, the LEADTOOLS SDK main installer does not include libraries and components for Intelligent Character Recognition (ICR). These components are in a separate installer available on our downloads page under the header "ICR and Additional OCR Languages". This can also be retrieved using our Download Manager.

To ensure this package installs correctly, make sure that there aren't any LEADTOOLS demos running or debugging. Also ensure any other projects currently in development aren't running or debugging as well. Note ICR functionality is only available when using the OmniPage engine.

This adds "Icr" to the OcrZoneType enumeration. The OcrZone.ZoneType property can be set to this value in code programatically.

This package also includes additional runtime files. See our documentation on "Files to be Included with your Application" and ensure the proper ones are deployed alongside your application.

For a demonstration of ICR functionality, open the OCR Multi-Engine Demo located in your installation folder.
C:\LEADTOOLS21\Shortcuts\OCR - MICR - ICR - OMR\.NET Framework Class Libraries\Main OCR Demos

The LEAD engine supports ICR in a 64-bit environment. It'll be necessary to run the 64-bit demo to test with this engine. The OmniPage engine supports ICR in both 32 and 64-bit environments, so either demo can be used.

When prompted, select either the "LEADTOOLS - LEAD Engine" or the "LEADTOOLS - OmniPage OCR Engine" option in the dropdown.

Draw a new zone.


Select the "Zone Properties" option.


In the dialogue for the Properties, set the dropdown for Type to Icr.


This instructs the OCR engine to treat the contents of that zone as handwritten characters when the recognition is performed. To recognize the document, select OCR -> "Recognize Document", then OCR -> "Show Recognized Words" to view the results.
