Add barcodes to PDF

This article demonstrates how to add barcodes to a PDF document.

With PDFKit it is possible to add multiple types of barcodes to your PDF document, such as regular 128 bit barcodes, PDF barcodes and QR codes among others.

//create a new PDF and add a single page to it
Document doc = new Document();
Page page = new Page(PageSize.Letter);
doc.Pages.Add(page);

//create a new barcode shape and add it to the page
Code3of9BarcodeShape shape = new Code3of9BarcodeShape();
page.VisualOverlay.Add(shape);

//specify some members of the barcode shape
shape.Location = TextLocation.BelowEmbedded;
shape.Transform = new TranslateTransform(50, 600);
shape.Width = 200;
shape.Height = 50;
shape.Data = "123456789";

//create a new qr code shape and add it to the page
QRBarcodeShape qr = new QRBarcodeShape();
page.VisualOverlay.Add(qr);

//specify some members of the qr shape
qr.Location = TextLocation.BelowEmbedded;
qr.Transform = new TranslateTransform(50, 400);
qr.Width = 50;
qr.Height = 50;
qr.Data = "your data here";

using (FileStream stream = new FileStream(
    @"..\..\out.pdf", FileMode.Create, FileAccess.Write))
{
    doc.Write(stream);
}

'create a new PDF and add a single page to it
Dim doc As New Document()
Dim page As New Page(PageSize.Letter)
doc.Pages.Add(page)

'create a new barcode shape and add it to the page
Dim shape As New Code3of9BarcodeShape()
page.VisualOverlay.Add(shape)

'specify some members of the barcode shape
shape.Location = TextLocation.BelowEmbedded
shape.Transform = New TranslateTransform(50, 600)
shape.Width = 200
shape.Height = 50
shape.Data = "123456789"

'create a new qr code shape and add it to the page
Dim qr As New QRBarcodeShape()
page.VisualOverlay.Add(qr)

'specify some members of the qr shape
qr.Location = TextLocation.BelowEmbedded
qr.Transform = New TranslateTransform(50, 400)
qr.Width = 50
qr.Height = 50
qr.Data = "your data here"

Using stream As New FileStream("..\..\out.pdf", FileMode.Create, FileAccess.Write)
	doc.Write(stream)
End Using
