Barcode Generation : Code 128

Anyone know of any libraries for creating code 128 barcodes ? Ideally we would like to include them in a PDF form.

Any suggestions greatly appreciated.

I use gbarcode quite heavily and with great success:

What you really need is something to generate pdf's for you and then you can use any barcode font to generate your text as a barcode format... i will suggest pdflib as it really integrates nicely with its ruby api's

that example there is java but you will have a very similar one in ruby..

have you gotten it out? code 128can be generated using many platforms,you can take this code 128 for example
