# boxConvolve(kernelSize:edgeMode:destination:)

Convolves an 8-bit-per-channel, 4-channel interleaved pixel buffer with a box filter.

## Declaration

```swift
func boxConvolve(kernelSize: vImage.Size, edgeMode: vImage.EdgeMode<Pixel_8888>, destination: vImage.PixelBuffer<Format>)
```

## Parameters

- `kernelSize`: The convolution kernel size. The operation interprets even dimensions as the next odd number.
- `edgeMode`: The convolution edge mode.
- `destination`: The destination pixel buffer.
