# glassDistortion()

Distorts an image by applying a glass-like texture.

## Declaration

```swift
class func glassDistortion() -> any CIFilter & CIGlassDistortion
```

## Return Value

Return Value The distorted image.

## Discussion

Discussion This method applies the glass distortion filter to an image. This effect distorts an image by applying a glass texture from the raised portions of the texture map image. The glass distortion filter uses the following properties: The following code creates a filter that results in a glass-like distortion applied to the image: func glassDistortion(inputImage: CIImage, textureImage: CIImage) -> CIImage {     let filter = CIFilter.glassDistortion()     filter.inputImage = inputImage     filter.textureImage = textureImage     filter.center = CGPoint(x: 1791, y: 1344)     filter.scale = 500     return filter.outputImage! }
