# blurredRectangleGenerator()

Generates a blurred rectangle.

## Declaration

```swift
class func blurredRectangleGenerator() -> any CIFilter & CIBlurredRectangleGenerator
```

## Return Value

Return Value A CIImage containing a blurred rectangle.

## Discussion

Discussion Creates a CIImage containing a blurred rectangle. The resulting image size is the extent of the rectangle plus any additional space required for the blur effect. The blurred rectangle filter uses the following properties: The following code creates a filter that generates a blurred red rectangle with a width of 200 x 100 pixels. func blurredRectangle() -> CIImage {     let filter = CIFilter.blurredRectangleGenerator()     filter.extent = CGRect(x: 0, y: 0, width: 200, height: 100)     filter.color = CIColor.red     filter.sigma = 10.0     return filter.outputImage! }
