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.

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.
