Remarks

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

The OMR zones of a page are zones with OcrZone.ZoneType set to OcrZoneType.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.

Example
