OcrZoneFillMethod DetectFillMethod()

function Leadtools.Forms.Ocr.IOcrPage.DetectFillMethod()

OcrZoneFillMethod DetectFillMethod(); 

Return Value

This method tries to determine the type of the text in the IOcrPage globally (e.g. handprinted, machine printed or dot-matrix printed text).

This method is useful when this is a page with an unknown or uncertain type of text. (This case quite often occurs when you work with filled forms.) 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

Note, you must either add zones manually or automatically to this page (with AutoZone) before you can call DetectFillMethod.

To update the zones of this IOcrPage with the detected fill method, use UpdateFillMethod

Note: This method will always return OcrZoneFillMethod.Defaultfor the LEADTOOLS OCR Advantage Engine since this engine doesn't support fill methods.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
