#summary Reference for PDF417

=PDF417=

The PDF417 barcode symbology is 2D stacked-linear barcode that can encode full 256 character extended-ASCII.

Variants:

• Truncated PDF417 is a shortened form of the PDF417 barcode that is used in applications where the space for the symbol is restricted.
• [MicroPdf417 MicroPDF417] is a smaller variant of the PDF417 barcode.
• [Hibc HIBC PDF417] is a variant of PDF417 that should be used when encoding HIBC formatted data.

Standards: ISO/IEC 15438, DD ENV 12925.

===Data and Options===

• The data field can contain any extended ASCII data.
• 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.
• 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 columns option specifies the number of columns (or groups of bars) in the output symbol, from 1 to 30.
• The rows option specifies the minumum 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 compact option is used to create a compact/truncated PDF417 symbol that has fewer bars per row that a standard symbol and hence is more narrow.
• The format option is used to select between full and micro format symbol types. By default, format=full symbols will be generated.
• 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.
• The ccc option identifies this symbol as a CC-C 2D component of a [Gs1Composite GS1 Composite] symbol.
