Working with Recognition Results Using OCR Professional

Show in webframe

To add code to an existing project in order to work with recognition results:

1.	Start with the program you created in Recognize Pages.
2.	Define the following global IDs in Ezfunc.h in the OCR_Ltdoc2 directory:

#define IDM_GET_OUTPUTFORMAT 207
#define IDM_SAVE_RESULTS 208

3.	Edit EZFUNC.RC file in the OCR_Ltdoc2 directory and add the following lines:

MAIN_MENU   MENU
BEGIN
   ...
   ...
   MENUITEM "Get Output Formats"    IDM_GET_OUTPUTFORMAT
   MENUITEM "Save Results"          IDM_SAVE_RESULTS
END

4.	In the MainWndProc procedure, add the following code to the switch statement for WM_COMMAND:

      case IDM_GET_OUTPUTFORMAT:
         {
            nRet = L_Doc2EnumOutputFileFormats(hDoc, EnumOutputFileFormatsCB, NULL);
            if (nRet != SUCCESS)
            {
               wsprintf (achBuff, TEXT("Error %d enumerating available file formats"), nRet);
               MessageBox (NULL, achBuff, TEXT("Error"), MB_OK);
            }
         }
         break;
      case IDM_SAVE_RESULTS:
         {
            RESULTOPTIONS2 ResOpts;

            memset(&ResOpts, 0, sizeof(RESULTOPTIONS2));
            nRet = L_Doc2GetRecognitionResultOptions(hDoc, &ResOpts, sizeof(RESULTOPTIONS2));
            if (nRet == SUCCESS)
            {
               ResOpts.Format = DOC2_WORD_2000;
               ResOpts.FormatLevel = DOC2_FORMAT_LEVEL_AUTO;

               L_Doc2SetRecognitionResultOptions(hDoc, &ResOpts);
               nRet = L_Doc2SaveResultsToFile (hDoc, TEXT("c:\\test.doc"));
               if (nRet != SUCCESS)
               {
                  wsprintf (achBuff, TEXT("Error %d in saving recognition results to a file"), nRet);
                  MessageBox (NULL, achBuff, TEXT("Error"), MB_OK);
               }
            }
         }
         break;

5.	Add the following function at the end of the code in EZFUNC.CPP in OCR_Ltdoc2 directory.

L_INT EXT_CALLBACK EnumOutputFileFormatsCB(DOC2_FORMATTYPE Format, L_VOID * pUserData)
{
   UNREFERENCED_PARAMETER(pUserData);

   TEXTFORMATINFO2 FormatInfo;
   L_INT nRet;
   L_TCHAR szBuffer[1024];

   memset(&FormatInfo, 0, sizeof(TEXTFORMATINFO2));
   nRet = L_Doc2GetTextFormatInfo(hDoc, Format, &FormatInfo, sizeof(TEXTFORMATINFO2));
   if (nRet == SUCCESS)
   {
      wsprintf(szBuffer, TEXT("Format Name = %s\nFormat DLL Name = %s\nFormat Ext Name = %s\n"),
              (FormatInfo.pszName) ? FormatInfo.pszName : TEXT(" "),
              (FormatInfo.pszDLLName) ? FormatInfo.pszDLLName : TEXT(" "),
              (FormatInfo.pszExtName) ? FormatInfo.pszExtName : TEXT(" "));

      MessageBox(NULL, szBuffer, TEXT("Format Info"), MB_OK);
      if (FormatInfo.pszName)
         GlobalFreePtr(FormatInfo.pszName);
      if (FormatInfo.pszDLLName)
         GlobalFreePtr(FormatInfo.pszDLLName);
      if (FormatInfo.pszExtName)
          GlobalFreePtr(FormatInfo.pszExtName);

   }

   return SUCCESS;
}

6.	Also, add the following statement before the MainWndProc function

L_INT EXT_CALLBACK EnumOutputFileFormatsCB(DOC2_FORMATTYPE Format, L_VOID * pUserData);

7.	Build SimpleLoad.exe.
8.	Run SimpleLoad.exe.
