Barcode not working

[jakobschonberg]

Expected Behavior

Produce a visible barcode (works in 1.31.3066.0)

Actual Behavior

Compiles and runs, but shows no barcode.

Steps to Reproduce the Behavior

Add this code to IssueSubmission/Program.cs

            MigraDoc.DocumentObjectModel.Tables.Table table = section.AddTable();
            table.AddColumn();
            table.AddRow();
            Barcode b = table[0, 0].Elements.AddBarcode();
            b.Type = BarcodeType.Barcode39;
            b.Code = "79834278";
            b.Width = 200;
            b.Height = 50;
            b.BearerBars = true;
            b.LineHeight = 50;
            b.LineRatio = 2;

Further information

This function does not handle the case where documentObject is a Barcode, so the object is never rendered:

Today I took the code that was originally provided in https://forum.pdfsharp.net/viewtopic.php?f=3&t=1215 (in 2010!) and modified it to render barcodes. The original patch needed very little modification to work with the current codebase and I made one additional change to add a default minimum font size for the readable text printed below a barcode. I'll see if I can create a pull request. I've only ever done that once before on Github so I'll have to try to remind myself how it is done.
