Compact Aztec Code

Compact Aztec Code is a reduced form of the Aztec Code barcode that is used in applications where the space for the symbol is restricted.

Variants:

Aztec Code is the larger, more popular variant.
Aztec Runes are a set of small barcode symbols that are used for special applications.

Standards: ISO/IEC 24778, ANSI/AIM BC13 - ISS Aztec Code

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
- ^ECI000000 to ^ECI999999: ECI indicators
The eclevel option is used to specify the percentage of error correction to be applied when expanding the data, by default 23.
The ecaddchars option is used to specify how many additional error correction characters to apply the data once expanded by the eclevel percentage, by default 3.
The layers option is used to specify a particular number of layers in which to encode the data, between 1 and 4. By default the encoder will create a symbol with be minimal number of layers to encode the given data.
The readerinit option denotes that the symbol is used for programming the barcode reader. Reader programming is only compatible with 1-layer Compact Aztec Code symbols.
The raw option denotes that the data field is providing the input as a pre-encoded bitstream suitable for direct low-level encoding.
