Data Matrix Rectangular - bwipp/postscriptbarcode GitHub Wiki

The Data Matrix Rectangular symbology is a rectangular variant of Data Matrix.

Variants:

• Data Matrix is the standard square variant of the symbology.
• Data Matrix Rectangular Extension is a variant of Data Matrix Rectangular that provides a greater range of symbol dimensions.

Standards: ISO/IEC 16022, ANSI/AIM BC11 - ISS Data Matrix.

• The data field can contain any extended ASCII data. The default interpretation of data by readers is in accordance with ISO/IEC 8859-1. When supported by the receiver characters from other code pages can be encoded using Extended Channel Interpretation (ECI).
• When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value. This is useful for specifying unprintable characters.
• When the parsefnc option is specified, non-data function characters can be specified by escape sequences:
  • ^FNC1: FNC1. Recommendation: Use GS1 DataMatrix for encoding GS1 AI syntax data.
  • ^PROG: PROG - Reader programming
  • ^ECI000000 to ^ECI999999: ECI indicators
• Whenever the data field contains suitable input, the encoder will compress ISO/IEC 15434 structured data (internally using the 05 Macro and 06 Macro codewords.)
• When the dotty option is specified the modules are rendered as dots rather than squares. The dot radius can be adjusted using the inkspread option.
• Deprecated: Use Data Matrix Rectangular Extension. The dmre option enables Data Matrix Rectangular Extension symbols based on the ISO/IEC standard, which increases the number of rectangular symbol sizes available.
• The columns and rows options are used to specify the size of the symbol.
• The version option can also be used to specify the symbol size, as version=RxC. Valid options are 8x18, 8x32, 12x26, 12x36, 16x36, 16x48.
• If columns, rows and version are unspecified the encoder will default to creating a symbol that is the minimum size to represent the given data.
• The raw option denotes that the data field is providing the input as pre-encoded codewords in ^NNN format, suitable for direct low-level encoding.
