How to scale the QR Code?

The QR barcode can be scaled by setting the XDimension property of the PdfQRBarcode class. The following code example is for scaling QR Code.

C#

//Loads the pdf
PdfLoadedDocument pdfDoc = new PdfLoadedDocument("sample.pdf");
//create the barcode 
PdfQRBarcode qrCode = new PdfQRBarcode();
qrCode.Text = "Ac-42";
//Set dimension to scale the barcode
qrCode.XDimension = 10;
//Draw the Barcode
qrCode.Draw(pdfDoc.Pages[0], new PointF(10, 10));
//Save the File 
pdfDoc.Save("Output.pdf");
pdfDoc.Close();
