Leadtools.Forms.Ocr Namespace > IOcrDocumentManager Interface : MissingSymbol Property



The MissingSymbol Property is available as an add-on to the LEADTOOLS Document and Medical Imaging toolkits.

Gets or sets the character used as a symbol for the missing characters in the final output document.

Syntax

Visual Basic (Declaration) 
Property MissingSymbol As Char
Visual Basic (Usage)Copy Code
Dim instance As IOcrDocumentManager
Dim value As Char
 
instance.MissingSymbol = value
 
value = instance.MissingSymbol
C# 
char MissingSymbol {get; set;}
C++/CLI 
property char MissingSymbol {
   char get();
   void set (    char value);
}

Property Value

The character used as a symbol for the missing characters in the final output document.

Example

For an example, refer to IOcrDocumentManager.

Remarks

The missing symbol is a special character that replaces another character that was recognized by the engine but could not be represented in the final output document, since the character does not exist in the current code page.

During the conversion to the final output document the IOcrDocument.Save or IOcrDocument.SaveXml methods will try to find a replacement character with a similar shape for one not supported by the current code page. Only if this attempt was not successful the missing symbol will be sent into the final output document.

The default missing symbol is "^" (the circumflex character)

For more information on recognition and rejected and missing symbols, refer to IOcrPage.Recognize.

Note: This property is not supported in the LEADTOOLS OCR Advantage Engine

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
