Members

Member	Description
Asian	The zone contains Asian characters.
DashDigit	Dash-digit zone filling method.
Default	Default zone filling method. The IOcrPage.AutoZone(OcrProgressCallback callback) method will set all the fill method of the zones found to this value. You can set the zone filling method to another type by using IOcrPage.AutoZone(OcrZoneParser zoneParser, OcrZoneFillMethod fillMethod, LogicalUnit zonesUnit, OcrProgressCallback callback) with fillMethod set the zone type desired.
DotDigit	Dot-digit zone filling method.
DraftDotMatrix24	24-pin draft dot-matrix zone filling method. It denotes a 24-pin draft dot-matrix printout.
DraftDotMatrix9	9-pin draft dot-matrix zone filling method. It denotes a 9-pin draft dot-matrix printout.
Icr	Handprinted zone filling method.
Micr	Magnetic ink character filling method. Mostly used in bank checks.
NoRecognition	No recognition will be attempted.
OcrA	OCR-A zone filling method.
OcrB	OCR-B zone filling method.
OmniFont	Omnifont zone filling method. It denotes a machine printed text with any typeface which is not too stylized.
Omr	Optical mark zone filling method. It denotes a possible marking within the zone.

Remarks

A fill method must have been assigned to all zones in their OcrZone.FillMethod properties before processing.

Not all fill methods are available to all engines. To determine which fill methods are available use IOcrZoneManager.GetSupportedFillMethods. Trying to set a fill method not available to the engine will cause an error.

Each zone needs to be associated with a OcrZoneRecognitionModule and OcrZoneFillMethod. This is needed because some recognition modules support more than one fill method, and some fill methods are accepted by more than one recognition module.

It is important to ensure that the recognition module/fill method pair is suitable. For more information on permitted recognition module/fill method pairs refer to An Overview of OCR Recognition Modules.

Note that the auto-zoning IOcrPage.AutoZone will create the zones with the value OcrZoneFillMethod.Default in their OcrZone.FillMethod properties.

Example

For an example, refer to IOcrPage.AutoZone.
