Returns all words that have been recognized for specific recognized page.

Syntax

Visual Basic (Declaration)
Public Function GetRecognizedWords( _ ByVal pageIndex As Integer _ ) As IList(Of RasterDocumentRecognizedWords)

Visual Basic (Usage)	Copy Code
`Dim instance As RasterDocumentEngine Dim pageIndex As Integer Dim value As IList(Of RasterDocumentRecognizedWords) value = instance.GetRecognizedWords(pageIndex)`

C#
public IList<RasterDocumentRecognizedWords> GetRecognizedWords( int pageIndex )

Managed Extensions for C++
public: IList<RasterDocumentRecognizedWords>* GetRecognizedWords( int pageIndex )

C++/CLI
public: IList<RasterDocumentRecognizedWords>^ GetRecognizedWords( int pageIndex )

Parameters

pageIndex: Index of the page for which all of the recognized words are being retrieved. This is a zero-based index.
