PDF417 Barcode

PDF417 is a 2D barcode format used in a variety of applications such as transport, identification cards, and inventory management.

Variants:

• Compact PDF417 is a shortened form of the PDF417 barcode that is used in applications where the space for the symbol is restricted.
• MicroPDF417 is a smaller variant of the PDF417 barcode.

Data and Options

• The data field supports all 256 ASCII characters.
• The Error Correction allows the symbol to endure some damage without causing loss of data. You can choose an Error correction level from 0 to 8, the default is to choose a standard level of error correction that is determined by the encoded data length.
• The Columns option specifies the number of columns in the output symbol, from 1 to 30.
• The Compact option is used to create a Compact PDF417 symbol, also known as Truncated PDF417, that uses less area than the normal PDF417 barcode. This option should be used primarily in a clean environment, since it is more susceptible to damage.

If you want to use non-printable or special characters in a barcode, you can use escape sequences. An escape sequence always start with a backslash ('\') followed by the sequence itself.

• \n      New Line
• \r       Carriage Return
• \\      The backslash \ itself
• \xhh   For encoding bytes or ASCII-characters in hexadecimal notation

You can also enter the names of these control characters as plain text embedded in « »:
