Overview

The Data Matrix 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 encoding option denotes the high-level encoding scheme for the input data, either byte, ascii, edifact, c40, text or x12. The default is byte encoding which permits any extended-ASCII character in the data but may be less compact than other formats for certain types of input.
  
• The rows and columns options are used to specify the size of the symbol, either square or rectangular, one of:
  
• Square: 10x10,12x12, 14x14, 16x16, 18x18, 20x20, 22x22, 24x24, 26x26, 32x32, 36x36, 40x40, 44x44, 48x48, 52x52, 64x64, 72x72, 80x80, 88x88, 96x96, 104x104, 120x120, 132x132, 144x144
• Rectangular: 8x18, 8x32, 12x26, 12x36, 16x36, 16x48
• If the columns and rows are unspecified, the encoder will default to creating a (non-rectangular) symbol that is the minimum size to represent the given data.
  
• 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.
