# minimumCompositing()

Blends colors from two images by computing minimum values.

## Declaration

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

## Return Value

Return Value The modified image.

## Discussion

Discussion This method applies the minimum compositing filter to an image. The effect calculates the minimum value for each color component in the input and background images. The filter then uses the resulting color to create the output image. The minimum compositing filter uses the following properties: The following code creates a filter that results in the output image becoming brighter with both images’ colors: func minimumCompositing(inputImage: CIImage, backgroundImage: CIImage) -> CIImage {     let colorBlendFilter = CIFilter.minimumCompositing()     colorBlendFilter.inputImage = inputImage     colorBlendFilter.backgroundImage = backgroundImage     return colorBlendFilter.outputImage! }
