PDF417 (Portable Data File) Barcode

PDF417 (Portable Data File) is a stacked linear two-dimensional bar code used in a variety of applications; primarily transport, postal, identification card and inventory management. It has spawned an Open Source decoder project together with an Open Source encoder.

The PDF417 bar code is also called a symbol bar code and usually consists of 3 to 90 rows, each of which is like a small linear bar code.

The following properties are specific to the PDF417 type and available in the Property Grid under the Symbology property:

  • Columns
  • Specifies the number of bar code columns, which allows you to control the logic width of the bar code.
  • Compaction Mode
  • Specifies whether textual information or a byte array should be used as the bar code's data.
  • Error Correction Level
  • Specifies the amount of redundancy built into the bar code's coding, to compensate for calculation errors.
  • Rows
  • Specifies the number of bar code rows, which allows you to control the logic height of the bar code.
  • Truncate Symbol
  • Specifies whether the special end-symbol should be appended to the bar code.
  • Y to X Ratio
  • Specifies the height-to-width ratio of a logical unit's graphic representation.
