As for barcodes: They are only lines of different widths. If you have the source of that Java class, you could reimplement it in Python, and, if they are part of the documents you are going to print with PDF, integrate that with your generated document. Both PDF libraries mentioned allow you to directly draw lines of a specified width, and import a GIF.
Recently there was an article in http://slashdot.org about some nice college where students were forced to wear an ID sign with their Social Security Number as barcode (and a Pepsi logo ;). The school authorities claimed that it was OK as the number was "encoded". It included a link to the description of the barcode format which seemed quite easy both to read and to implement, even as alternating black and white gif stripes. -------------- Hannu
