# divideBlendMode()

Divides color values to blend colors.

## Declaration

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

## Return Value

Return Value The modified image.

## Discussion

Discussion This method applies the divide-blend mode filter to an image. The effect divides the background image color values by the color values of the input image, resulting in the output image. The divide-blend mode filter uses the following properties: The following code creates a filter that brightens and inverts colors in the background image: func divideBlendMode(inputImage: CIImage, backgroundImage: CIImage) -> CIImage {     let divideBlendMode = CIFilter.divideBlendMode()     divideBlendMode.inputImage = inputImage     divideBlendMode.backgroundImage = backgroundImage     return divideBlendMode.outputImage! }
