The Codablock F barcode symbology is 2D stacked-linear barcode that consists of a number of stacked Code 128 symbols. It can encode full 256 character extended-ASCII.

Variants:

• HIBC Codablock F is a variant of Codablock F that should be used when encoding HIBC formatted data.

Standards: USS Codablock F.

• The data field can consist of any extended-ASCII data. The default interpretation of data by readers is in accordance with ISO/IEC 8859-1.
• FNC4 function characters will be inserted automatically to allow the encoding of extended ASCII characters.
• 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:
  • ^FNC1: FNC1
  • ^FNC3: FNC3
• The columns option specifies the number of columns in the symbol, default 8.
• The rows option specifies the number of rows in the symbol, between 2 and 44.
• If rows is unspecified the encoder will default to the smallest number of rows that can hold the given data.
