# droste()

Stylizes an image with the Droste effect.

## Declaration

```swift
class func droste() -> any CIFilter & CIDroste
```

## Return Value

Return Value The distorted image.

## Discussion

Discussion This method applies the Droste filter to an image. This effect creates a Droste effect that distorts the image by repeating smaller versions of the same image within itself. The Droste filter uses the following properties: The following code creates a filter that results in the image becoming a repeated, scaled pattern: func drosteFilter(inputImage: CIImage) -> CIImage {     let filter = CIFilter.droste()     filter.inputImage = inputImage     filter.insetPoint1 = CGPoint(         x: inputImage.extent.size.width * 0.2,         y: inputImage.extent.size.height * 0.2     )     filter.insetPoint0 = CGPoint(         x: inputImage.extent.size.width * 0.8,         y: inputImage.extent.size.height * 0.8     )     filter.periodicity = 1     filter.rotation = 0     filter.strands = 1     filter.zoom = 1     return filter.outputImage!.cropped(to: inputImage.extent) }
