[SerializableAttribute()]
public enum class OcrOmrZoneState : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable

Value	Member	Description
0x00000000	Unfilled	The mark is unfilled (or unchecked).
0x00000001	Filled	The mark is filled (or checked).

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 is no 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.

For an example, refer to IOcrOmrOptions.
