public int OmrConfidence {get; set;}

'Declaration

Public Property OmrConfidence As Integer

'Usage

Dim instance As NativeOcrZone
Dim value As Integer
 
instance.OmrConfidence = value
 
value = instance.OmrConfidence

public int OmrConfidence {get; set;}

public int getOmrConfidence()
public void setOmrConfidence(int value)

 <br/>get_OmrConfidence();<br/>set_OmrConfidence(value);<br/>Object.defineProperty('OmrConfidence');

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
NativeOcrZone.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.
NativeOcrZone.OmrConfidence	A number between 0 and 100 (where 100 is maximum confidence) that specifies the OCR engine confidence in the recognition status in NativeOcrZone.OmrState.

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

Property	Value
NativeOcrZone.FillMethod	Set to NativeOcrZoneFillMethod.Omr.
NativeOcrZone.RecognitionModule	Set to NativeOcrZoneRecognitionModule.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 NativeOcrZone.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.
