# convolve(with:divisors:biases:edgeMode:destination:) Convolves an 8-bit-per-channel, 4-channel interleaved pixel buffer with separate kernels for each channel. ``` func convolve(with kernels: (vImage.ConvolutionKernel2D, vImage.ConvolutionKernel2D, vImage.ConvolutionKernel2D, vImage.ConvolutionKernel2D), divisors: (Int32, Int32, Int32, Int32)?, biases: (Int32, Int32, Int32, Int32) = (0, 0, 0, 0), edgeMode: vImage.EdgeMode, destination: vImage.PixelBuffer) ``` ## 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. ## See Also --- Copyright © 2026 Apple Inc.
