The BARCODEWRITEAZTEC structure contains information for writing Aztec symbols.

Members

uStructSize

Size of this structure in bytes. Use the sizeof() operator to calculate this value.

ulFlags

Reserved for future use.

nXModule

Specifies the module size of the printed AZTEC barcode, in 0.001 inches. The module size = (the value of nXModule) X (the number of Modules in each row). The module is a "cell" that is used to make the symbol's grid. In the middle of the symbol is a set of concentric squares (used to orient the symbol), at the center of which is a single, black "module".

SymbolSize

Specifies which symbol size to use when writing an Aztec barcode. The following values are possible:
BARCODE_AZTEC_CODE
BARCODE_AZTEC_CODE_Compact1
BARCODE_AZTEC_CODE_Compact2
BARCODE_AZTEC_CODE_Compact3
BARCODE_AZTEC_CODE_Compact4
BARCODE_AZTEC_CODE_Full1
BARCODE_AZTEC_CODE_Full2
BARCODE_AZTEC_CODE_Full3
BARCODE_AZTEC_CODE_Full4
BARCODE_AZTEC_CODE_Full5
BARCODE_AZTEC_CODE_Full6
BARCODE_AZTEC_CODE_Full7
BARCODE_AZTEC_CODE_Full8
BARCODE_AZTEC_CODE_Full9
BARCODE_AZTEC_CODE_Full10
BARCODE_AZTEC_CODE_Full11
BARCODE_AZTEC_CODE_Full12
BARCODE_AZTEC_CODE_Full13
BARCODE_AZTEC_CODE_Full14
BARCODE_AZTEC_CODE_Full15
BARCODE_AZTEC_CODE_Full16
BARCODE_AZTEC_CODE_Full17
BARCODE_AZTEC_CODE_Full18
BARCODE_AZTEC_CODE_Full19
BARCODE_AZTEC_CODE_Full20
BARCODE_AZTEC_CODE_Full21
BARCODE_AZTEC_CODE_Full22
BARCODE_AZTEC_CODE_Full23
BARCODE_AZTEC_CODE_Full24
BARCODE_AZTEC_CODE_Full25
BARCODE_AZTEC_CODE_Full26
BARCODE_AZTEC_CODE_Full27
BARCODE_AZTEC_CODE_Full28
BARCODE_AZTEC_CODE_Full29
BARCODE_AZTEC_CODE_Full30
BARCODE_AZTEC_CODE_Full31
BARCODE_AZTEC_CODE_Full32
The default value is BARCODE_AZTEC_CODE, which allows the function to choose the smallest value that can contain the complete input message.

ErrorCorrectionRate

Specifies the error detection and correction rate (Reed-Solomon error encoding) when writing an Aztec barcode, in percent. Possible values range from 5% to 95%. The specification suggests that 23% be used. The ErrorCorrectionRate is the percentage of error correction codewords out of all codewords. The default value is 23%.

QuietZone

(Optional) Specifies the quiet zone value when writing an Aztec barcode. The default value is 0.

AztecRune

Specifies whether to write an Aztec Rune barcode.

AztecRuneValue

Specifies the value to be encoded when writing an Aztec Rune barcode. Possible values range from 0 to 255.

Comments

pBARCODEWRITEAZTEC is a pointer to a BARCODEWRITEAZTEC structure. Where the function parameter type is pBARCODEWRITEAZTEC, you can declare a BARCODEWRITEAZTEC variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pBARCODEWRITEAZTEC variable is necessary only if your program requires a pointer.

The smallest symbol size is 15 x 15 pixels. Sizes increase by increments of 4.

The AZTEC standard specifies 37 different sizes of the Aztec code (see the values for SymbolSize). The maximum data capacity varies, depending on the size and Error Correction level.

LEADTOOLS supports the ECI 000003 encodable character set:

• All 8-bit values can be encoded.
• Values 0 to 127 are interpreted according to the U.S. national version of ISO/IEC 646.
• Values 128-255 are interpreted in accordance with ISO/IEC 8859-1.
