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.
Note: Note: Please refer to the Class
Reference documentation for more information about the properties and methods
stated in this document.
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.

Setting up dimensions and quiet zones:
All values for barcode dimensions are expressed
in INCHES by default. However, Barcode Professional supports other unit
of measurement such as Millimeter, Centimeter, and Mils.
For modifying the unit of measurement for barcoding, please set up the BarcodeUnit
property as needed.
-
Set the BarWidth and BarHeight
properties (Values are expressed in Inches)
-
Set the QuietZone property (Value is expressed in Inches)
-
Set the Code property with the value to encode.

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
