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 Properties panel under the Symbology property:
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.
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.
