it's part of PDF 2 specified by the PMD entry in the fields dictionary. {quote} (Required; barcode fields only; PDF 2.0) The PaperMetaData generation parameters dictionary. The entries of this dictionary are instructions to a barcode encoding module of an interactive PDF processor on how to generate the barcode image. {quote} Barcode symbologies are PDF417, QRCode, or DataMatrix. The output format generated by Adobe (with a quick test - so might not be generally the case) is a bitmap but quickly scanning through the spec I couldn't find if that is required by the spec or if it could als be vectors.
