## Description

Learn how to generate a PDF document and add a barcode to it.

![Pdf with Barcodes](https://www.telerik.com/document-processing-libraries/documentation/assets/96ee907cfae942d3492877522d419d32/pdf-with-barcodes.png)

> note Starting with **Q1 2025**, RadPdfProcessing provides support for adding barcodes (1D and 2D) to a PDF document: [Adding Barcode into a Document](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/model/formsource/barcode).

## Solution

To add a barcode to a PDF document, consider using the [WinForms BarcodeView](https://docs.telerik.com/devtools/winforms/controls/barcodeview/overview):

1. [Generate an image of the barcode](https://docs.telerik.com/devtools/winforms/controls/barcodeview/how-to/export-to-image).

2. Add the [image to the PDF document](https://www.telerik.com/document-processing-libraries/documentation/knowledge-base/pdf-from-images-with-radfixeddocumenteditor). The following example demonstrates this approach:

```csharp
   Telerik.WinControls.UI.Barcode.QRCode qrCode1 = new Telerik.WinControls.UI.Barcode.QRCode();
   RadBarcodeView radBarcodeView = new RadBarcodeView();
   radBarcodeView.BindingContext = new BindingContext();
   qrCode1.Version = 1;
   radBarcodeView.Symbology = qrCode1;
   radBarcodeView.Text = "radBarcodeView1";
   radBarcodeView.Value = "1234567";
   radBarcodeView.Invalidate();
   System.Drawing.Image img = radBarcodeView.ExportToImage(200, 200);
   string imageFilePath = "barcodeImage.png";
   img.Save(imageFilePath, System.Drawing.Imaging.ImageFormat.Png);

   RadFixedDocument fixedDocument = new RadFixedDocument();     
   RadFixedDocumentEditor documentEditor = new RadFixedDocumentEditor(fixedDocument);
   FileStream fileStream = new FileStream(imageFilePath, FileMode.Open);
   Telerik.Windows.Documents.Fixed.Model.Resources.ImageSource _imageSource = new Telerik.Windows.Documents.Fixed.Model.Resources.ImageSource(fileStream);
   documentEditor.InsertImageInline(_imageSource);
   documentEditor.InsertLineBreak();
   documentEditor.Dispose();
   PdfFormatProvider provider = new PdfFormatProvider();
   string outputFilePath = "output.pdf";
   File.Delete(outputFilePath);
   using (Stream output = File.OpenWrite(outputFilePath))
   {
       provider.Export(fixedDocument, output);
   }
   Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
```

## Notes

* The WinForms BarcodeView method is suitable for applications where a barcode image can be generated and saved before adding it to the PDF: [Generating a Bar Code Image outside WinForms](https://docs.telerik.com/devtools/winforms/knowledge-base/gridview-generating-barcode-image-non-winforms).
