Working with Recognition Results Using LEADTOOLS OCR Module - LEAD Engine

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

1. Start with the program you created in Recognize Pages Using LEADTOOLS OCR Module - LEAD Engine.

2. Define the following global IDs in Ezfunc.h in the OCR_Ltocr directory:

   #define IDM_SAVE_RESULTS            207 

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

   MAIN_MENU   MENU   
   BEGIN   
      ...    
      ...    
      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_SAVE_RESULTS: 
   { 
      L_TCHAR szFileName[MAX_PATH] = {0}; 
      lstrcpy(szFileName, TEXT("C:\\Users\\Public\\Documents\\output.pdf")); 
      nRet = L_OcrDocument_Save(hDocument, szFileName, DOCUMENTFORMAT_PDF, MyCallback, NULL); 
      if (nRet != SUCCESS) 
      { 
         wsprintf (achBuff, TEXT("Error %d in saving recognition results to a file"), nRet); 
         MessageBox (NULL, achBuff, TEXT("Error"), MB_OK); 
      } 
      else 
      { 
         wsprintf (achBuff, TEXT("Successfully saved recognition results to %s"), szFileName); 
         MessageBox (NULL, achBuff, TEXT("Notice"), MB_OK); 
      } 
   } 
   break; 

5. Build SimpleLoad.exe.

6. Run SimpleLoad.exe.
