# circularWrap()

Distorts an image by increasing the distance of the center of the image.

## Declaration

```swift
class func circularWrap() -> any CIFilter & CICircularWrap
```

## Return Value

Return Value The distorted image.

## Discussion

Discussion This method applies the circular wrap filter to an image. This effect wraps an image around a transparent circle. The distortion of the image increases with the distance from the center of the circle. The circular wrap filter uses the following properties: The following code creates a filter that results in a circular image generated from the input image: func circularWrap(inputImage: CIImage) -> CIImage {    let filter = CIFilter.circularWrap()     filter.inputImage = inputImage     filter.center = CGPoint(         x: inputImage.extent.size.width/2,         y: inputImage.extent.size.height/2     )     filter.angle = .pi     filter.radius = 90     return filter.outputImage! }

let text = CIFilter.textImageGenerator() text.text = "Core Image" text.fontSize = 100 text.fontName = "Chalkboard" text.outputImage! circularWrap(inputImage: text.outputImage!)
