The OMR zones of a page have the L_OcrZone.ZoneType property set to L_OcrZoneType_OMR.
Currently LEADTOOLS OCR Module - LEAD Engines does not supports auto detection of OMR zones. Instead, you need to: add the OMR zones manually to the page by setting their boundary (through L_OcrZone.Bounds, the zone type through L_OcrZone.ZoneType and adding the zone to the page using the L_OcrPage_AddZone or L_OcrPage_InsertZone before calling L_OcrPage_Recognize.
To use OMR in LEADTOOLS, you need a special key to unlock the OMR capabilities. For more information, refer to Setting a Runtime License.
