Compact PDF417

Compact PDF417

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

Also known as: Truncated PDF417

Variants:

• PDF417 is the larger, more popular variant.
• MicroPDF417 is a smaller variant of the PDF417 barcode.
• HIBC PDF417 is a variant of PDF417 that should be used when encoding HIBC formatted data.

Standards: ISO/IEC 15438, DD ENV 12925, AIM USS - PDF417.

Data and Options

• The data field can contain any extended ASCII data. The default interpretation of data by readers is in accordance with ISO/IEC 8859-1. When supported by the receiver characters from other code pages can be encoded using Extended Channel Interpretation (ECI).
• When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters.
• When the parsefnc option is specified, non-data function characters can be specified by escape sequences:
  • ^ECI000000 to ^ECI811799: ECI indicators
• The eclevel option is used to specify the error correction level, from 1 to 5. The default is to choose a standard level of error correction that is determined by the encoded data length.
• The fixedeclevel option will prevent the error correction level from being opportunistically raised when a better fix to the current matrix is possible.
• The columns option specifies the number of columns (or groups of bars) in the output symbol, from 1 to 30.
• The rows option specifies the minimum number of rows in the symbol, from 3 to 90.
• If rows is unspecified the encoder will select a number that creates a symbol that is the minimum size to represent the given data.
• The rowmult option is used to specify how tall each bar is, with respect to the minimum module width. The default is 3.
• The raw option denotes that the data field is providing the input as a pre-encoded codewords in ^NNN format, suitable for direct low-level encoding.
