# checkerboardGenerator()

Generates a checkerboard image.

## Declaration

```swift
class func checkerboardGenerator() -> any CIFilter & CICheckerboardGenerator
```

## Return Value

Return Value The generated image.

## Discussion

Discussion This method generates a checkerboard pattern as an image. The effect requires the size, sharpness, and color properties to create the pattern. The checkerboard generator filter uses the following properties: The following code creates a filter that generates a black-and-white checkered pattern: func checkerBoard() -> CIImage {     let checkerBoardGenerator = CIFilter.checkerboardGenerator()     checkerBoardGenerator.setDefaults()     checkerBoardGenerator.center = CGPoint(x: 0, y: 0)     checkerBoardGenerator.color0 = .white     checkerBoardGenerator.color1 = .black     checkerBoardGenerator.width = 40     checkerBoardGenerator.sharpness = 1     return checkerBoardGenerator.outputImage! }
