To show a linear or a 2D barcode in your application you should simply create a barcode widget, set its properties and place it somewhere in you application. The following code demonstrates how to create and initialize an EAN13 linear barcode and place it in a stack panel:

NLinearBarcode barcode = new NLinearBarcode();
barcode.HorizontalPlacement = ENHorizontalPlacement.Center;
barcode.VerticalPlacement = ENVerticalPlacement.Center;
barcode.Symbology = ENLinearBarcodeSymbology.EAN13;
barcode.Text = "0123456789012";
stackPanel.Add(barcode);

This code results in the following barcode:

Nevron Open Vision's barcode library lets you easily create barcode images by using the proper barcode painter class. For example the code below creates a 2D barcode image by the QR code standard:

NMatrixBarcodePainter painter = new NMatrixBarcodePainter();
painter.Symbology = ENMatrixBarcodeSymbology.QrCode;
painter.Text = "https://www.nevron.com";
NRaster qrRaster = painter.CreateRaster(100, 100, NRaster.DefaultResolution);
NImage qrImage = new NImage(qrRaster);

This code results in the following QR code image:

You can easily insert barcodes in rich text documents. All you have to do is to create and initialize a barcode widget and then create and add a widget inline to a paragraph of the rich text document. As all other widgets barcode widgets used in rich text documents are automatically converted to images when saving the document to a text format not native to NOV Text Editor (DOCX, HTML, RTF, etc.).

// Create a barcode widget
NBarcode barcode = new NLinearBarcode(ENLinearBarcodeSymbology.EAN13,"0123456789012");
NWidgetInline widgetInline = new NWidgetInline(barcode);

// Add the linear barcode widget inline to a paragraph
paragraph.Inlines.Add(widgetInline);

You can easily insert barcodes in Nevron Diagram shapes. All you have to do is to create and initialize a barcode widget and set it to the Widget property of a shape:

// Create a barcode widget
NMatrixBarcode barcode = new NMatrixBarcode(ENMatrixBarcodeSymbology.QrCode, "https://www.nevron.com");
           
// Create a shape and place the barcode widget in it
NShape shape = new NShape();
shape.SetBounds(100, 100, 100, 100);
shape.Widget = barcode;
activePage.Items.Add(shape);
