The key for the default input image.

## Declaration

```swift
let IKFilterBrowserDefaultInputImage: String
```

## Discussion

Discussion The associated value is the CIImage object to use as the default input image for the filter preview. Setting the image to nil causes Image Kit to use the image supplied by the framework. You can also set the input image and other parameters during the notification IKFilterBrowserWillPreviewFilterNotification.
