How do I use the NetBarcode library to display an Barcode?

Question

It's the first time I've used library. Hence the question I asked about the library: link

Add a barcode to my label? On the Website it says for a label it goes with it:

var barcode = new Barcode ("543534", Type.Code128, true);

But when I try to assign the value to the label, it doesn't work. So how do I have to use this library to add the barcode to a label?

Because I can't do much here:

if I want to get a barcode on a label?

The easy way is to define a ValueConverter

public class StringToBarcodeConverter : IValueConverter
{
    public object? Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value is string s)
        {
            var bc = new NetBarcode.Barcode(s, true);
            return bc.GetByteArray();
        }
        return null;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

and use that inside the XAML.

<Image Source="{Binding Barcode, 
  Converter={StaticResource StringToBarcodeConverter}, 
  Mode=OneWay}" />
