# convolve(with:divisors:biases:edgeMode:destination:)

Convolves an 8-bit-per-channel, 4-channel interleaved pixel buffer with separate kernels for each channel.

## Declaration

```swift
func convolve(with kernels: (vImage.ConvolutionKernel2D<Int16>, vImage.ConvolutionKernel2D<Int16>, vImage.ConvolutionKernel2D<Int16>, vImage.ConvolutionKernel2D<Int16>), divisors: (Int32, Int32, Int32, Int32)?, biases: (Int32, Int32, Int32, Int32) = (0, 0, 0, 0), edgeMode: vImage.EdgeMode<Pixel_8888>, destination: vImage.PixelBuffer<Format>)
```

## Parameters

- `kernels`: The convolution kernels.
- `divisors`: An optional tuple of four values that the operation adds to the sum of weighted pixels before it applies the divisor.
- `biases`: A tuple of four values 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.
