This method tries to determine the type of the text in the zones of this IOcrPage (e.g. handprinted, machine printed or dot-matrix printed text). This method only looks into zones having the OcrZoneFillMethod.Default value in their OcrZone.FillMethod property. When a zone with this qualification is found, this method will update the following:

• OcrZone.FillMethod will be updated to the detected value.
• OcrZone.RecognitionModule will be updated to OcrZoneRecognitionModule.Default.

If the detection was unsuccessful, both properties of the zone remain intact.

The types of zones that can be detected with this method are:

1. OcrZoneFillMethod.OmniFont
2. OcrZoneFillMethod.DraftDotMatrix9
3. OcrZoneFillMethod.DraftDotMatrix24
4. OcrZoneFillMethod.Icr
5. OcrZoneFillMethod.NoRecognition

To detect the global fill method of a page, use DetectFillMethod

Note: This method is not supported in the LEADTOOLS OCR Advantage Engine, any call to this method will have no effect.

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
