# bokehBlur()

Applies a bokeh effect to an image.

## Declaration

```swift
class func bokehBlur() -> any CIFilter & CIBokehBlur
```

## Return Value

Return Value The blurred image.

## Discussion

Discussion This method applies the bokeh blur filter to an image. The effect targets a circular area of pixels defined by the radius and blurs the area. The filter adds smaller intense blur rings. The bokeh blur filter uses the following properties: The following code creates a filter that adds a softer blur to the input image:     func bokehBlur(inputImage: CIImage) -> CIImage? {

let bokehBlurFilter = CIFilter.bokehBlur()         bokehBlurFilter.inputImage = inputImage         bokehBlurFilter.ringSize = 0.1         bokehBlurFilter.ringAmount = 0         bokehBlurFilter.softness = 1         bokehBlurFilter.radius = 20         return bokehBlurFilter.outputImage     }
