Overview

Code One was the earliest public domain 2D matrix-style barcode. It is used by the health care and recycling industry and can encode full 256 character extended-ASCII.

Invoking

• The data field can consist of any ASCII data for standard and T-type symbols.
• Note: S-type symbols are special in that they represent a numeric value which must be binary encoded using ^NNN notation.
• 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, e.g. ^029 for GS, etc.
• The version option is used to specify the size and type of the symbol:
• A, B, C, D, E, F, G, H - for standard format symbols (default automatic selection)
• version=T-16, version=T-32, version=T-48 - T-type symbols
• version=S-10, version=S-20, version=S-30 - S-type symbols
• 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.
