BCGaztec Class
Aztec code comes from the 2D barcode family. You can encode a lot of information in only one barcode.
All the ASCII characters from 0 to 255 are supported. The barcode size will be determined by the number of data needed to be encoded and the chosen error correction level.
You can pass in ECI mode with the function setTilde().
This class inherits from the BCGBarcode2D class.
This class is also available for WebControl: BCGaztec

Methods Explanation
setErrorLevel(int level) — Sets the error correction level of the barcode
Description
It is the error correction level percentage before drawing the barcode.
The level must be between 0 and 99.
The default value is 23.
It is the error correction level percentage before drawing the barcode.
The level must be between 0 and 99.
The default value is 23.
setSize(int size) — Sets the size of the barcode
Description
The size of the final barcode will be decided automatically depending on the data you give and the error correction level percentage you have chosen.
But, you can specify different values to this method to get a different code. There are the possible values:
The size of the final barcode will be decided automatically depending on the data you give and the error correction level percentage you have chosen.
But, you can specify different values to this method to get a different code. There are the possible values:
- BCGaztec.AZTEC_SIZE_SMALLEST : The code will be the smallest possible
- BCGaztec.AZTEC_SIZE_COMPACT : The code will try to be a compact code if possible
- BCGaztec.AZTEC_SIZE_FULL : The code will be in full mode (with the reference grid)
setStructureAppend(int snum, int st) — Specifies the data will be expended on many barcodes without identifier
Description
The Aztec code data can be separated on many different barcodes.
The first argument is the barcode number (beginning with 1), the second argument is the total number of barcodes you have. No identifier is set for the barcode. Make sure you have no identifier for every barcode in the group.
It is possible to encode the data on a maximum of 26 different barcodes.

Returns
true on success, false on failure.
true on success, false on failure.
setStructureAppend(int snum, int st, string sname) — Specifies the data will be expended on many barcodes with identifier
Description
The Aztec code data can be separated on many different barcodes.
The first argument is the barcode number (beginning with 1), the second argument is the total number of barcodes you have. The last argument specifies an identifier for you barcodes group. This argument must stay the same for every barcode.

setTilde(bool accept) — Modifies the use of the tilde character ~
Description
By putting true to this the argument for this method, the tilde characters (ASCII 126) will be processed as special characters. There are the special characters you can write.
The default value is true.

setOffsetX(int offsetX) — Specifies the X offset
Description
Specifies the X offset of the barcode in pixel multiplied by the scale. The required size returned by getMaxSize() will sera modified accordingly.
