The Aztec barcode is a matrix barcode type that does not require quiet zones:
From the 2D Barcode Action dialog box, select Properties:
The Aztec Properties dialog box will display:
The density of the barcode. 96 dpi (dots-per-inch) is low resolution, while 600 dpi is high resolution. The default is 96 dpi.
Error correction level
The Reed-Solomon error correction level placed in the symbol. More error correction creates a bigger symbol that is less likely to be damaged. Exceeding a level of 23 is not recommended, especially with larger amounts of data.
Add reader initialization symbol
Default unchecked. The reader intialization symbol is needed for older barcode scanners. If checked, the reader initilization symbol will be added to the Aztec barcode.
NOTE: Characters, text, numeric values and bytes of data can be encoded in an Aztec barcode. A two-dimensional imaging device such as a CCD (charge-coupled device) camera is necessary to scan the symbology.
