I think I was able to do it by copying the COSDictionary object directly (I found I can set it at the Widget level, not the PDField level). However, the question remains how can I create a COSDictionary from scratch, only using its textual value? Or should I keep a file with a Barcode field somewhere on the system and copy the value from it whenever I want to create such a field?
