Support for determining the various zone types, recognition modules and fill methods supported by the OCR engine.

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) 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 by using IsZoneTypeSupported first.
To get all the supported zone types use GetSupportedZoneTypes.
This example will show the different zone types supported by the LEADTOOLS OCR Module - LEAD Engine.
