Leadtools.Forms.Ocr Namespace > IOcrPage Interface : DetectFillMethod Method



Detects the type of text in this IOcrPage.

Syntax

Visual Basic (Declaration) 
Overridable Function DetectFillMethod() As OcrZoneFillMethod
Visual Basic (Usage)Copy Code
Dim instance As IOcrPage
Dim value As OcrZoneFillMethod
 
value = instance.DetectFillMethod()
C# 
virtual OcrZoneFillMethod DetectFillMethod()
C++/CLI 
virtual OcrZoneFillMethod DetectFillMethod(); 

Return Value

An OcrZoneFillMethod enumeration member that specifies the type of text in this IOcrPage.

Example

For an example, refer to AutoZone.

Remarks

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.

Requirements

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