   state ,
   value

Parameters

state
The OMR state for this character.
value
The character value.
Remarks

OMR stands for Optical Mark Recognition. For more information refer to Using OMR in LEADTOOLS .NET OCR.

When performing OMR recognition, you can obtain the OMR results by inspecting the OcrZone.OmrState property. Moreover the engine will add a character to represent each zone (mark) state into the recognition results. This character will then be outputted to the final document when IOcrDocument.Save or IOcrDocument.SaveXml is called.

The character will also be present as the zone data when calling IOcrPage.GetRecognizedCharacters.

The default characters used in the IOcrEngine is as follows:

State Value
OcrOmrZoneState.Unfilled 0
OcrOmrZoneState.Filled 1

You can get the current values using the GetStateRecognitionCharacter method, you can also change them using the SetStateRecognitionCharacter method. If you do not want any OMR characters to show up in the final document, you can set all state characters to ' ' (a space character).

Example
For an example, refer to IOcrOmrOptions.
