We have an existing iPhone application with barcode functionality based off of the zxing library. The app serves our needs perfectly, except that it cannot handle PDF417 barcodes. We need to have this portion of the library updated. We need someone who has previous experience with the zxing library and its issues with PDF417s; ideally someone who has resolved them in a previous build. Attached is a sample PDF417 file. We also need the solution to be completed quickly.
