You can use the TWAIN and OCR Engine provided through the LEADTOOLS SDK to scan a paper through a scanner, and then display the information in your application. After scanning your document, you can get access to the scanned image of your document through the TwainAcquirePageEventArgs Image property, and then pass the image you will receive into the IOcrPageCollection AddPage method which will allow you to read the information. You can try building on the following code for this: private void Form1_Load(object sender, EventArgs e) { _viewer = new ImageViewer(); _viewer.Dock = DockStyle.Fill; _viewer.BackColor = Color.DarkGray; Controls.Add(_viewer); _viewer.BringToFront(); } // This will start the TWAIN session private void acquireImageToolStripMenuItem_Click(object sender, EventArgs e) { _session = new TwainSession(); _session.Startup( this .Handle, "manufacturer" , "productFamily" , "version" , "application" , TwainStartupFlags.None); _session.SelectSource(string.Empty); _session.AcquirePage += new EventHandler (_session_AcquirePage); _session.Acquire(TwainUserInterfaceFlags.Show); } private void _session_AcquirePage(object sender, TwainAcquirePageEventArgs e) { // Set the scanned image in the ImageViewer _viewer.Image = e.Image; // Get and Set the scanned image to the viewer using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD)) { // Start the engine using default parameters ocrEngine.Startup( null , null , null , OcrRuntimeDir); // Create an OCR document using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument()) { // Add this image to the document IOcrPage ocrPage = ocrDocument.Pages.AddPage(e.Image, null ); // Pass the Image for OCR to grab data ocrPage.AutoZone( null ); // Auto Recognize } } } https://www.leadtools.com/help/sdk/v21/tutorials/dotnet-core-minimum-code-required-to-ocr-files.html https://www.leadtools.com/help/sdk/v21/tutorials/dotnet-winforms-acquire-an-image-from-a-twain-source.html
