This Symbology is also known as Aztec Barcode, ANSI/AIM BC13 ITS/97/002

Aztec Code is a two-dimensional matrix symbology containing dark and light square data modules. It has a finder pattern of concentric square rings centered on a single dark module located in the center of the symbol. A two-dimensional imaging device such as a CCD camera is necessary to scan the symbology. Aztec Code can encode all 8-bit values (0-127 ASCII and 128-255 ISO 8859-1, Latin Alphabet No.1) and performs Reed Solomon Error Correction based on user-selectable percentages (5% to 95%). Aztec Code is used for small item marking applications using a wide variety of printing and marking technologies.

Aztec Code implementation in Barcode Professional supports FNC1, Extended Channel Interpretation (ECI) and "Aztec Runes" which is a series of 256 small machine-readable marks compatible with Aztec Code, available for special applications.

Aztec Code Barcode

In order to get an Aztec Code barcode image, please follow these steps:

• Set the Symbology property to AztecCode.
• Set the AztecCodeFormat property.
• Set the AztecCodeErrorCorrection property.
• Set the AztecCodeRune property if needed to a value from 0 up to 255.
• Setting up dimensions and quiet zones:
  • Set the AztecCodeModuleSize property (Value is expressed in Inches)
  • Set the QuietZoneWidth property (Value is expressed in Inches)
  • Set the TopMargin and BottomMargin properties (Values are expressed in Inches)
• Set the Code property with the value to encode.
• If desired, you can use the tilde character "~" to specify special characters in the input data. To do that you must set the AztecCodeProcessTilde property to True. Read more about how it works.

When working with Aztec Code tilde processing keep in mind the following rules:

• ~1: is used to represent the FNC1 code
• ~7NNNNNN: is used to specify the Extended Channel Interpretation (ECI) and NNNNNN is a value between 000000 and 999999. Default is ECI 000003 which represents the ISO 8859-1 Latin Alphabet No. 1
• ~dNNN: is used to represent a byte value in decimal notation. NNN must be a numeric value ranging from 000 to 255
• ~hXX: is used to represent a byte value in hexadecimal notation. XX must be a hexadecimal value ranging from 00 to FF
