You can access the instance of the IOcrZoneManager used by an IOcrEngine through the IOcrEngine.ZoneManager property.
When calling the IOcrPage.AutoZone method on a page, the generated zone's type (OcrZone.ZoneType), recognition module (OcrZone.RecognitionModule) and fill method (OcrZone.FillMethod) will always be one of the supported values as reported by the IOcrZoneManager.
Before manually changing any of the above zone properties, you must determine whether the particular value is supported by this instance of IOcrEngine. You do this by using the instance of IOcrZoneManager of the engine through the IOcrEngine.ZoneManager property as follows:
To get all the supported zone types, recognition modules or fill methods use GetSupportedZoneTypes, GetSupportedRecognitionModules and GetSupportedFillMethods respectively.
