# pointillize()

Applies a pointillize effect to an image.

## Declaration

```swift
class func pointillize() -> any CIFilter & CIPointillize
```

## Return Value

Return Value A CIImage containing the pointillized image.

## Discussion

Discussion This filter applies a pointillize effect to an image. The effect generates an output image made of small, single-color, circular points distributed on a randomly perturbed grid. The pointillize filter uses the following properties: The following code applies the pointillize filter with a radius of 40 pixels. func pointillize(inputImage: CIImage) -> CIImage {     let pointillizeFilter = CIFilter.pointillize()     pointillizeFilter.inputImage = inputImage     pointillizeFilter.radius = 40     pointillizeFilter.center = CGPoint(x: 0,y: 0)     return pointillizeFilter.outputImage! }
