# encode(commandBuffer:sourceImage:destinationImage:)

Encodes a kernel into a command buffer.  The ensuing operation proceeds out-of-place.

## Declaration

```swift
func encode(commandBuffer: any MTLCommandBuffer, sourceImage: MPSImage, destinationImage: MPSImage)
```

## Parameters

- `commandBuffer`: A valid command buffer to receive the encoded filter.
- `sourceImage`: A valid source image.
- `destinationImage`: A valid destination image to be overwritten by the results.

## Discussion

Discussion The destinationImage object may not alias the sourceImage object.
