Working with Recognition Results

Take the following steps to add code to the existing project that will let you recognize pages:

1.

Start with the program you created in Working with Zones.

2.

Add a command button to your form and name it as follows:

 

Name

Caption

 

GETOUTPUTFORMAT

Get Output Format

 

SAVEDOCUMENT

Save Document

3.

Code the GETOUTPUTFORMAT button's click procedure as follows:

Private Sub GETOUTPUTFORMAT_Click()
   Dim nRet As Long
   nRet = LEADRasterDoc.GetOutputFileFormats
   If (nRet <> 0) Then
      MsgBox "Error" + Str(nRet) + "in enumerating available file formats"
   End If
End Sub

4.

Code the SAVEDOCUMENT button's click procedure as follows:

Private Sub SAVEDOCUMENT_Click()
   Dim nRet As Long
   nRet = LEADRasterDoc.GetRecognitionResultOptions
   If (nRet = 0) Then
      LEADRasterDoc.ResultOptions.FormatLevel = FORMATLEVEL_FULL
      LEADRasterDoc.ResultOptions.DocumentOptions.PaperSizeMode = SELPREDEFINED
      LEADRasterDoc.ResultOptions.DocumentOptions.PaperType = PAPER_A4
   End If

   LEADRasterDoc.SetRecognitionResultOptions
   nRet = LEADRasterDoc.SaveDocument ("c:\test.doc")
   If (nRet <> 0) Then
      MsgBox "Error" + Str(nRet) + "in saving recognition result to a file"
   End If
End Sub

5.

Code the EnumOutputFileFormats Event procedure as follows:

Private Sub LEADRasterDoc_EnumOutputFileFormats (ByVal Format As LTRASTERDOCLib.FORMATTYPE) 
   Dim nRet As Long

   nRet = LEADRasterDoc.GetFileFormatInfo (Format) 
   If (nRet = 0) Then
      MsgBox "Format Name = " + LEADRasterDoc.FileFormatInfo.FormatName + Chr$(13) + _
      "Format DLL Name = " + LEADRasterDoc.FileFormatInfo.DLLName + Chr$(13) + _
      "Format Ext Name = " + LEADRasterDoc.FileFormatInfo.ExtName

      Select Case (LEADRasterDoc.FileFormatInfo.Type) 
         Case OUTTYPE_PLAIN
            MsgBox "Format Type = Plain"
   
         Case OUTTYPE_WORD_PROCESSOR
            MsgBox "Format Type = Word Processor"

         Case OUTTYPE_TRUE_WORD_PROCESSOR: 
            MsgBox "Format Type = True Word Processor"
   
         Case OUTTYPE_TABLE
            MsgBox "Format Type = Table"
   
         Case OUTTYPE_UNKNOWN
            MsgBox "Format Type = Unknown"
   
      End Select

   End If
End Sub

6.

Run your program to test it.

7.

Save this project to use for testing other code samples.
