public int OmrConfidence {get; set;}

'Declaration
 
Public Property OmrConfidence As Integer

'Usage
 
Dim instance As OcrZone
Dim value As Integer
 
instance.OmrConfidence = value
 
value = instance.OmrConfidence

public int OmrConfidence {get; set;}

 get_OmrConfidence();
 set_OmrConfidence(value);

public:
property int OmrConfidence {
   int get();
   void set (    int value);
}

Property Value

A number between 0 and 100 (where 100 is maximum confidence) that indicate the after-recognition confidence this IOcrEngine has in the OmrState value of this zone.

Remarks

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

After you call IOcrPage.Recognize, all the OMR zones in the page will have the OMR properties updated as follows:

Property	Description
OcrZone.OmrState	Either OcrOmrZoneState.Filled if the mark is recognized to be filled or checked, or OcrOmrZoneState.Unfilled if the mark is recognized to be unfilled or unchecked.
OcrZone.OmrConfidence	A number between 0 and 100 (where 100 is maximum confidence) that specifies the OCR engine confidence in the recognition status in OcrZone.OmrState.

The OMR zones of a page are zones with the following properties:

Property	Value
OcrZone.FillMethod	Set to OcrZoneFillMethod.Omr.
OcrZone.RecognitionModule	Set to OcrZoneRecognitionModule.Omr.

All LEADTOOLS OCR engines support OMR. However, there isn't any current support for auto-detecting OMR zones in a page, you have to add the OMR zones manually to the page by setting their boundary (through OcrZone.Bounds, the fill method and recognition module as described above and adding the zone to the page using the IOcrPage.Zones collection before calling IOcrPage.Recognize.

To use OMR in LEADTOOLS, you need a special key to unlock the OMR capabilities. For more information, refer to Unlocking Special LEAD Features.

Example

For an example, refer to IOcrOmrOptions.
