# motionBlur()

Creates motion blur on an image.

## Declaration

```swift
class func motionBlur() -> any CIFilter & CIMotionBlur
```

## Return Value

Return Value The blurred image.

## Discussion

Discussion This method applies the motion blur filter to an image. The filter uses the angle of a single row of pixels to determine the direction of the motion effect. The motion blur filter uses the following properties: The following code creates a filter that adds a motion blur to the input image:     func motionBlur(inputImage: CIImage) -> CIImage? {

let motionBlurFilter = CIFilter.motionBlur()         motionBlurFilter.inputImage = inputImage         motionBlurFilter.angle = 0         motionBlurFilter.radius = 20         return motionBlurFilter.outputImage     }
