I wondering if there is any workaround to add text with barby (something like the wiki link).
<% barcode_value = "099999333" %>
<% barcode = Barby::Code39.new(barcode_value) %>
<% File.open('code39XQW.png', 'w'){|f| %>
<% f.write barcode.to_png(:margin => 3, :xdim => 2, :height => 55) %>
<% } %>
Thanks.
