DotCode

DotCode

The DotCode symbology is 2D matrix-style barcode that can encode full 256 character extended-ASCII.

Also known as: Ribbon Code

Variants:

• GS1 DotCode is a variant of DotCode that should be used when encoding data that is in GS1 Application Identifier standard format.

Standards: AIM - ISS DotCode.

Data and Options

• 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 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 DotCode for encoding GS1 AI syntax data.
  • ^FNC2: FNC2
  • ^FNC3: FNC3
• The ratio is used to specify the aspect ratio of the symbol. The default is 1.5.
• The columns and rows options are used to specify the size of the symbol. When these are not specified a symbol is generated that maintains the selected aspect ratio.
• Deprecated: Use only if performance is a concern. The fast option is used to enable the optional high-speed symbol masking algorithm.
