Normative standards: The normative standard for the PDF 417 barcode symbology is called ISO/IEC 15438:2001 (ISO International Standard).

The term Macro PDF (or Macro PDF417) is used when concatenating multiple PDF417 barcode symbols (see below - Structured Append). PDF417 is also known under the names PDF-417, Portable Data File and PDF 417. In the year 2007 the company was acquired by Motorola. PDF 417 was developed 1991 by the company Symbol. Pure 2-D barcode symbologies like Data Matrix or QR Code encode the information in the presence of black or white dots at specific positions - and not by using bar:space ratios. For that reason the printing accuracy and a suitable printer resolution are important for high quality PDF417 symbols. The ratio of the widths of the bars (or spaces) to each other encode the information in a PDF417 symbol.

The size of the symbol can be modified by the user. The overall shape of a PDF417 is rectangular. This is the reason why the PDF417 symbology is sometimes called a "stacked linear symbology". A single PDF417 symbol can be imagined as multiple linear bar-codes (called "rows") stacked above each other. PDF417 is a 2D barcode symbology (two-dimensional barcode) with very high data density. driver licenses, passports) and document management. for shipping labels), identification (e.g. The 2D barcode symbology is mostly utilized in the areas of logistic applications (especially in the automotive industry), transport systems (e.g. The PDF417 symbology is mainly used in Europe and in the United States. I need to edit this data and re-generate a valid PDF417 barcode.PDF-417 is used for encoding large amounts of data, usually up to one or two-hundred characters are encoded in a single symbol. Parsing the real barcode gives such data in AAMVA format. I've also tried to parse it and many online parsing tools worked well. The result barcode image was different with the original one.

I've tried to read the original barcode with barcode parser, convert it to ASCII string, and re-generate a new PDF417 barcode with that string.
