PDF 417 Specification



PDF 417 (Portable Data File 417) is a stacked symbology and was invented by Ynjiun Wang in 1991 at Symbol Technologies. PDF 417 consists of 17 modules each containing 4 bars and spaces. PDF417 also utilizes Reed-Solomon error correction routines, enabling damaged symbols to be reconstructed. The symbology is capable of encoding the entire (255 character) ASCII set as well as 2725 data characters in a single barcode.

Use Caret (^)
The UseCaret propeties is set to true by default which is only apply to Code128, UccEan128, Sscc18, Scc14, PDF417, MacroPDF417, QR Code, and DataMarix etc. where full ASCII is accepted as encoding. The 3 digits data following the caret will be treated as ASCII code, e.g. ^010 is \n; ^009 is a tab; ^065 is character 'A'.
