# code128BarcodeGenerator()

Generates a high-density, linear barcode.

## Declaration

```swift
class func code128BarcodeGenerator() -> any CIFilter & CICode128BarcodeGenerator
```

## Return Value

Return Value The generated image.

## Discussion

Discussion This method generates a Code 128 barcode as an image. Code 128 is a high-density linear barcode defined in the ISO/IEC 15417:2007 standard. Use this filter to generate alphanumeric or numeric-only barcodes. The barcode can contain any of the 128 ASCII characters. The Code 128 barcode filter uses the following properties: The following code creates a filter that generates a Code 128 barcode: func code128Barcode(barcode: String) -> CIImage {     let code128Barcode = CIFilter.code128BarcodeGenerator()     code128Barcode.message = barcode.data(using: .ascii)!     code128Barcode.quietSpace = 5     code128Barcode.barcodeHeight = 20     return code128Barcode.outputImage! }
