# convolve(with:bias:edgeMode:destination:)

Convolves a 32-bit-per-channel, 4-channel interleaved pixel buffer.

## Declaration

```swift
func convolve(with kernel: vImage.ConvolutionKernel2D<Float>, bias: Float? = nil, edgeMode: vImage.EdgeMode<Pixel_FFFF>, destination: vImage.PixelBuffer<Format>)
```

## Parameters

- `kernel`: The convolution kernel.
- `bias`: An optional value that the operation adds to the sum of weighted pixels before it applies the divisor.
- `edgeMode`: The convolution edge mode.
- `destination`: The destination pixel buffer.
