# barcodeGenerator()

Generates a barcode as an image from the descriptor.

## Declaration

```swift
class func barcodeGenerator() -> any CIFilter & CIBarcodeGenerator
```

## Return Value

Return Value The generated image.

## Discussion

Discussion This method generates a custom barcode as an image. The effect uses barcode descriptors to specify properties of the generated barcode. The barcode generator uses the following property: The following code creates a filter that generates a QR code containing the text Johnny Appleseed. func barcode(inputMessage: Data) -> CIImage {    let barcodeGenerator = CIFilter.barcodeGenerator()     barcodeGenerator.barcodeDescriptor = CIQRCodeDescriptor(payload: inputMessage, symbolVersion: 1, maskPattern: 4, errorCorrectionLevel: .levelL)!     return barcodeGenerator.outputImage! }

let johnnyAppleseed: [UInt8] = [0x41, 0x04, 0xA6, 0xF6, 0x86, 0xE6, 0xE7, 0x92, 0x04, 0x17, 0x07, 0x06, 0xC6, 0x57, 0x36, 0x56, 0x56, 0x40, 0xEC] let data = Data(johnnyAppleseed)

let bImage = barcode(inputMessage: data)
