ValueMemberDescription
0Auto Automatically detect whether there is a printed frame (e.g. check box).
1WithoutFrame The OMR zone is inside the printed frame, so the printed frame is not visible.
2WithFrame The OMR zone is outside the printed frame, so the printed frame is visible.
Remarks

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

Frames stand for the check boxes that may exist around OMR fields. You can set the LEADTOOLS OCR engine to automatically detect these frames and take them into consideration when recognizing OMR fields. If you know whether the OMR fields contain frames, set the IOcrOmrOptions.FrameDetectionMethod accordingly to increase recognition performance and accuracy.

Example

For an example, refer to IOcrOmrOptions.
