How to generate linear barcodes on PDF Page in C#.NET

This is a simple C# example for PDF barcode creation.

// generate a Code 39 barcode
Linear linearBarcode = new Linear();
linearBarcode.Type = BarcodeType.CODE39;
linearBarcode.Data = "123456789";
linearBarcode.Resolution = 96;
linearBarcode.Rotate = Rotate.Rotate0;

// load PDF document, you can also load document like TIFF, Word, Excel & PPT
PDFDocument doc = new PDFDocument(@"c:\sample.pdf");

// get the first page
PDFPage page = (PDFPage)doc.GetPage(0);

// generate reimage of this barcode
Bitmap barcodeImage = linearBarcode.ToImage();

// add barcode image to the first page and the top left vertex of barcode image rectangle is at point(100,100)
page.AddImage(barcodeImage, new System.Drawing.PointF(100f, 100f));

// save changes to the PDF
doc.Save(@"c:\output.pdf ");

How to create QR Code 2D barcodes using C#.NET

Below are the steps and C# sample code to add QR Code barcode to a PDF page, and add a web link over the QR Code area on page.

  1. Create a QRCode object
  2. Set the QR Code properties
  3. Set the QR Code data value to a web link ""
  4. Set QR Code image width and height to 1 inch both.
  5. Create a PDFDocument object from an existing PDF file
  6. Add the qr code to the first page of the PDF document.
  7. Add a link action PDFLinkAction object to jump to a web page
  8. Save the PDF file

//  Create an QRCode
RasterEdge.XImage.BarcodeCreator.QRCode qrcode = new RasterEdge.XImage.BarcodeCreator.QRCode();
//  Set QRCode Version
qrcode.Version = RasterEdge.XImage.BarcodeCreator.QRCodeVersion.V1;
//  Set data encoding mode
qrcode.DataMode = RasterEdge.XImage.BarcodeCreator.QRCodeDataMode.Auto;
//  Set error correction level
qrcode.ECL = RasterEdge.XImage.BarcodeCreator.QRCodeECL.M;
//  Set data message to encode
qrcode.Data = "";
//  Set barcode size to 1 inch x 1 inch
qrcode.UOM = RasterEdge.XImage.BarcodeCreator.UnitOfMeasure.INCH;
qrcode.BarcodeWidth = 1F;
qrcode.BarcodeHeight = 1F;
//  Set image resolution to 96 dpi.
qrcode.Resolution = 96;
qrcode.AutoResize = true;
//  Set all margins to 0
qrcode.LeftMargin = 0;
qrcode.RightMargin = 0;
qrcode.TopMargin = 0;
qrcode.BottomMargin = 0;

String inputFilePath = "C:\\1.pdf";
String outputFilePath = "C:\\output.pdf";

PDFDocument doc = new PDFDocument(inputFilePath);
//  Draw the barcode at position (100, 200) in pixels on the 1st page.
BasePage page = doc.GetPage(0);
qrcode.DrawBarcode(page, 100, 200);

//  Create and add a link to the same area of the QRCode
PDFLinkAction action = PDFLinkActionURI.Create("");
//  Position (100, 200) in pixels; Width 96 pixels, Height 96 pixels
RectangleF area = new RectangleF(100, 200, 96, 96);
PDFLinkSetting link = new PDFLinkSetting(area, action);
//  Add the link to the 1st page.
PDFLinkHandler.AddLink(doc, 0, link);
