Overview

The QR Code symbology is 2D matrix-style barcode. It can encode full 256 character extended-ASCII.

Invoking

• 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, either L, M, Q or H. The default is M.
  
• The version option is used to specify the size of the symbol, 1 to 40 for full format symbols or M1, M2, M3 or M4 of micro format symbols.
• If unspecified, the encoder will select the version of the symbol that is the minimum size to represent the given data.
  
• The format option is used to select between full and micro format symbol types. By default, full format symbols will be generated.
• The raw option denotes that the data field is providing the input as a pre-encoded bitstream suitable for direct low-level encoding.
  
• Note: Micro format symbols require that the data be supplied in raw mode.
