# ninePartStretched()

Distorts an image by stretching it between two breakpoints.

## Declaration

```swift
class func ninePartStretched() -> any CIFilter & CINinePartStretched
```

## Return Value

Return Value The distorted image.

## Discussion

Discussion This method applies the nine-part stretched filter to an image. This effect distorts an image by stretching an image to the breakpoint properties while distorting the image based on the grow amount. The nine-part stretched filter uses the following properties: The following code creates a filter that results in a significantly warped image: func ninePartStretch(inputImage: CIImage) -> CIImage {     let filter = CIFilter.ninePartStretched()     filter.inputImage = inputImage     filter.setDefaults()     filter.breakpoint0 = CGPoint(x: 200, y: 200)     filter.breakpoint1 = CGPoint(x: inputImage.extent.size.width-200, y: inputImage.extent.size.height - 200)     filter.growAmount = CGPoint(x: 500, y: 500)     return filter.outputImage! }
