# blur(radius:opaque:)

Applies a Gaussian blur to this view.

## Declaration

```swift
nonisolated func blur(radius: CGFloat, opaque: Bool = false) -> some View

```

## Parameters

- `radius`: The radial size of the blur. A blur is more diffuse when its radius is large.
- `opaque`: A Boolean value that indicates whether the blur renderer permits transparency in the blur output. Set to true to create an opaque blur, or set to false to permit transparency.

## Discussion

Discussion Use blur(radius:opaque:) to apply a gaussian blur effect to the rendering of this view. The example below shows two Text views, the first with no blur effects, the second with blur(radius:opaque:) applied with the radius set to 2. The larger the radius, the more diffuse the effect. struct Blur: View {     var body: some View {         VStack {             Text("This is some text.")                 .padding()             Text("This is some blurry text.")                 .blur(radius: 2.0)         }     } }
