SymbolModel Property

Summary

Gets or sets the chosen symbol size when writing an Aztec barcode.

Syntax

Objective-C

C++/CLI

Java

Python

public AztecBarcodeSymbolModel SymbolModel { get; set; }

@property (nonatomic, assign) LTAztecBarcodeSymbolModel symbolModel;

public AztecBarcodeSymbolModel getSymbolModel() 
public void setSymbolModel(AztecBarcodeSymbolModel value)

public: 
property AztecBarcodeSymbolModel SymbolModel { 
   AztecBarcodeSymbolModel get(); 
   void set (    AztecBarcodeSymbolModel ); 
}

SymbolModel # get and set (AztecBarcodeWriteOptions)

Property Value

A AztecBarcodeSymbolModel enumeration member that determines the symbol size to use when writing an Aztec barcode. The default value is AztecBarcodeSymbolModel.AutoSize.

Remarks

The smallest Aztec Code symbol is AztecBarcodeSymbolModel.Compact1 (15x15 modules square), and the largest is AztecBarcodeSymbolModel.Full32(151 x 151). When the default value AztecBarcodeSymbolModel.AutoSize is used the encoder will choose a symbol size based on the size of input message and the ratio of error detection and correction
