Rectangular Micro QR Code - bwipp/postscriptbarcode GitHub Wiki

The Rectangular Micro QR Code (rMQR) symbology is a rectangular variant of QR Code that provides a compact symbol suitable for applications where a narrow, elongated symbol is required, such as labels and small cylindrical items.

Also known as: rMQR.

Variants:

• QR Code is the standard square variant of the symbology.
• Micro QR Code is a smaller square variant.

Standards: ISO/IEC 23941.

• 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, 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 QR Code for encoding GS1 AI syntax data.
  • ^ECI000000 to ^ECI999999: ECI indicators
• The version option is required and specifies the size of the symbol in RHxW format, where H is the height and W is the width in modules:
  • R7x43, R7x59, R7x77, R7x99, R7x139
  • R9x43, R9x59, R9x77, R9x99, R9x139
  • R11x27, R11x43, R11x59, R11x77, R11x99, R11x139
  • R13x27, R13x43, R13x59, R13x77, R13x99, R13x139
  • R15x43, R15x59, R15x77, R15x99, R15x139
  • R17x43, R17x59, R17x77, R17x99, R17x139
• The eclevel option is used to specify the error correction level:
  • eclevel=M - Medium (default)
  • eclevel=H - High
• The fixedeclevel option will prevent the error correction level from being opportunistically raised when a better fit to the selected symbol is possible.
• Deprecated: The suppresskanjimode option will prevent the use of Kanji Mode internal encodation. Some readers erroneously consider a Kanji Mode section as an indication that the affected part of the message should be interpreted using a Shift-JIS character set rather than as a data compaction strategy.
