# aztecCodeGenerator()

Generates a low-density barcode.

## Declaration

```swift
class func aztecCodeGenerator() -> any CIFilter & CIAztecCodeGenerator
```

## Return Value

Return Value The generated image.

## Discussion

Discussion This method generates an Aztec code as an image. The Aztec barcode code is a low-density barcode defined in the ISO/IEC 24778:2008 standard. This code is commonly used for transport ticketing or boarding passes. The Aztec code generator filter uses the following properties: The following code creates a filter that generates an Aztec barcode: func aztecCode(inputMessage: String) -> CIImage {     let aztecCodeGenerator = CIFilter.aztecCodeGenerator()     aztecCodeGenerator.correctionLevel = 15     aztecCodeGenerator.compactStyle = 0     aztecCodeGenerator.message = inputMessage.data(using: .ascii)!     aztecCodeGenerator.layers = 10     return aztecCodeGenerator.outputImage! }
