# zoomBlur()

Creates a zoom blur centered around a single point on the image.

## Declaration

```swift
class func zoomBlur() -> any CIFilter & CIZoomBlur
```

## Return Value

Return Value The blurred image.

## Discussion

Discussion This method applies the zoom blur filter to an image. This effect mimics the zoom of a camera when capturing the image. The zoom blur filter uses the following properties: The following code creates a filter that adds a zoom blur to the input image:     func zoomBlur(inputImage: CIImage) -> CIImage? {

let zoomBlurFilter = CIFilter.zoomBlur()         zoomBlurFilter.inputImage = inputImage         zoomBlurFilter.amount = 5         zoomBlurFilter.center = CGPoint(x: 150, y: 150)         return zoomBlurFilter.outputImage     }
