# applyGamma(_:destination:)

Applies a gamma function to a 32-bit pixel buffer.

## Declaration

```swift
func applyGamma(_ gamma: vImage.Gamma, destination: vImage.PixelBuffer<Format>)
```

## Parameters

- `gamma`: An enumeration that specifies either a used-defined or constant gamma.
- `destination`: The destination pixel buffer.

## Discussion

Discussion For example, the following code applies a gamma of `2.0` to a one-pixel pixel buffer: let buffer = vImage.PixelBuffer<vImage.PlanarF>(     pixelValues: [0.5],     size: vImage.Size(width: 1,                       height: 1))

buffer.applyGamma(.fullPrecision(2),                   destination: buffer)

// Prints "[0.25]" = [0.5²]. print(buffer.array)
