Working with Recognition Results(C++ Builder 6.0)

Working with Recognition Results (C++ Builder 6.0)

Take the following steps to add code to the existing project that will let you work with Recognition options:

1.	Start with the program you created in Working with Zones
2.	Add 2 buttons to your form and name them as follows:
	Name	Caption
	btnGetOutputFormat	Get Output Format
	btnSaveDocument	Save Document
3.	Handle the LEADRasterDocument1 OnEnumOutputFileFormats event, and code the LEADRasterDocument1EnumOutputFileFormats procedure as follows:

void __fastcall TForm1::LEADRasterDocument1EnumOutputFileFormats(
      TObject *Sender, FORMATTYPE Format)
{
   int nRet;
   AnsiString Msg;

   nRet= LEADRasterDocument1->GetFileFormatInfo ( Format );
   if ( nRet == 0 )
   {
      Msg= "Format Name = ";
      Msg= Msg + LEADRasterDocument1->FileFormatInfo->FormatName + "\n";
      Msg= Msg + "Format DLL Name = ";
      Msg= Msg + LEADRasterDocument1->FileFormatInfo->DLLName+ "\n";
      Msg= Msg + "Format Ext Name = ";
      Msg= Msg + LEADRasterDocument1->FileFormatInfo->ExtName;

      ShowMessage ( Msg );

      switch ( LEADRasterDocument1->FileFormatInfo->Type)
      {
         case OUTTYPE_PLAIN:
            ShowMessage ( "Format Type = Plain" );
         break;

         case OUTTYPE_WORD_PROCESSOR:
            ShowMessage ( "Format Type = Word Processor" );
         break;

         case OUTTYPE_TRUE_WORD_PROCESSOR:
            ShowMessage ( "Format Type = True Word Processor" );
         break;

         case OUTTYPE_TABLE:
            ShowMessage ( "Format Type = Table" );
         break;

         case OUTTYPE_UNKNOWN:
            ShowMessage ( "Format Type = Unknown" );
         break;
      }
   }
}

4.	Code the btnGetOutputFormat button's click procedure as follows:

void __fastcall TForm1::btnGetOutputFormatClick(TObject *Sender)
{
   int nRet;

   nRet= LEADRasterDocument1->GetOutputFileFormats ( );
   if ( nRet != 0 )
      ShowMessage ( "Error" + IntToStr(nRet) + "in enumerating available file formats" );
}

5.	Code the btnSaveDocument button's click procedure as follows:

void __fastcall TForm1::btnSaveDocumentClick(TObject *Sender)
{
   int nRet;

   nRet= LEADRasterDocument1->GetRecognitionResultOptions ( );
   if ( nRet == 0 )
   {
      LEADRasterDocument1->ResultOptions->FormatLevel= FORMATLEVEL_FULL;
      LEADRasterDocument1->ResultOptions->DocumentOptions->PaperSizeMode= SELPREDEFINED;
      LEADRasterDocument1->ResultOptions->DocumentOptions->PaperType= PAPER_A4;
   }

   LEADRasterDocument1->SetRecognitionResultOptions ( );
   nRet= LEADRasterDocument1->SaveDocument ( AnsiToOLESTR("c:\\test.doc") );
   if ( nRet != 0 )
      ShowMessage ( "Error" + IntToStr(nRet) + "in saving recognition result to a file" );
}

6.	Run your program to test it.
7.	Save the project to use as a starting point for other tasks in this tutorial.
