Barcode decoding project

I'm in processing to build a lib of barcode decoder, which can get image of scanned barcode, and decode the corresponding code as the return. I'm looking for programmer who has experience on this kind of work, pick up a couple of you, then wen can talk about how we can work together on my project. So when you bid, please let me know about your experience. If you have code that does certain type of barcode decoding, pls also let me know ownership of the code. Thanks!
