I'm trying to save Searchable PDF from TIF format images after OCR.
I writed PdfDocumentOptions, ImageOverText = true.
But Result pdf image is not searchable.
I'm using 17.5 .net C#, Advantate OCR.
Could you please explain to me what is wrong ?

 

         public void ThreadProc(object data)
        {
            ThreadData threadData = (ThreadData)data;
            string strImageFilePath = threadData.strImageFilePath;

            using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
            {
                 try
                {
                    string strModuleDirectory = String.Concat(m_strModuleDirectory, @"OcrAdvantageRuntime\");
                    ocrEngine.Startup(null, null, null, strModuleDirectory); //OcrAdvantageRuntime path

                    ocrEngine.LanguageManager.EnableLanguages(m_strLang); //"en"

                    CIniUtil clsIni = new CIniUtil();
                    string strPath = clsIni.getIniValue("ENVIR", "DstPath", threadData.strIniFilePath);
                    Directory.CreateDirectory(strPath);

                    string strFileName = Path.GetFileName(strImageFilePath);
                    string strDstImageFilePath = String.Concat(strPath, strFileName);

                    strDstImageFilePath = Path.ChangeExtension(strDstImageFilePath, "pdf");

                    DocumentWriter docWriter = ocrEngine.DocumentWriterInstance;
                    PdfDocumentOptions pdfOption = docWriter.GetOptions(DocumentFormat.Pdf) as PdfDocumentOptions;
                    pdfOption.ImageOverText = true;
                    pdfOption.AssemblyEnabled = true;
                    pdfOption.CopyEnabled = true;
                    pdfOption.EditEnabled = true;
                    pdfOption.Protected = false;
                    pdfOption.PageRestriction = DocumentPageRestriction.Relaxed;
                    docWriter.SetOptions(DocumentFormat.Pdf, pdfOption);
                   
                    using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument())
                    {
                        ocrDocument.Pages.AddPages(strImageFilePath, 1, -1, null);
                        ocrDocument.Pages.Recognize(null);
                        ocrDocument.Save(strDstImageFilePath, DocumentFormat.Pdf, null);
                    }
                }
                catch (Exception ex){}
                finally{}
            }

            threadData.WaitHandle.Set();
        } //ThreadProc

Debug Output of Debug/Release Mode is not searchable PDF.

Not debug mode (direct execution) is searchable PDF.

please why?

The version you provided is the product version. I need to know the File Version.

The only issue I can think of is if different dlls are being loaded when you directly execute, apposed from when you run from the Visual studios debugger.

Are you familiar with process explorer?

You can test and see which DLLs are being loaded by your application at any time by using Process Explorer. This is a free program that is available from http://technet.microsoft...sinternals/bb896653.aspx . Use this program and see what DLLs loaded when you run from the IDE as apposed to running from direct execution.

To see the DLLs, click on View -> Lower Pane View -> DLLs.

To see the path of the DLLs, click on View -> Select Columns, go to the DLL tab, and select the Path checkbox.

Hello! First, thank you for your response.

I have used process explorer but directory of  Leadstools dlls is same.

File version of Leadtools.Forms.Document.dll is 17.5.0.5,  Product Version is 17.5.4.0 and Runtime version is v4.0.30319.

What can i do for checking difference result between debug mode and not?

Try comparing the files being loaded by the process when run from the IDE as apposed to the process when your running from direct Execution.

The application is executing the same code regardless. The only thing I can think of would be if VS is loading different assemblies.

Another test would be to try this with the MainOCR Demo project.
