# linearLightBlendMode()

A combination of linear burn and linear dodge blend modes.

## Declaration

```swift
class func linearLightBlendMode() -> any CIFilter & CICompositeOperation
```

## Return Value

Return Value The blended image as a CIImage.

## Discussion

Discussion The linear-light blend mode combines the linear-dodge and linear-burn blend modes (rescaled so that neutral colors become middle gray). If the input image’s values are lighter than middle gray, the filter uses dodge; for darker values, the filter uses burn. The following code sample applies the linear-light blend mode filter to two images: func linearLightBlendMode(inputImage: CIImage, backgroundImage: CIImage) -> CIImage {     let filter = CIFilter.linearLightBlendMode()     filter.inputImage = inputImage     filter.backgroundImage = backgroundImage     return filter.outputImage! }
