# copy(sourceTexture:destinationTexture:)

Encodes a command that copies data from a texture to another.

## Declaration

```swift
func copy(sourceTexture: any MTLTexture, destinationTexture: any MTLTexture)
```

## Parameters

- `sourceTexture`: An doc://com.apple.metal/documentation/Metal/MTLTexture instance the command copies data from.
- `destinationTexture`: Another doc://com.apple.metal/documentation/Metal/MTLTexture instance the command copies the data into that has the same doc://com.apple.metal/documentation/Metal/MTLTexture/pixelFormat and doc://com.apple.metal/documentation/Metal/MTLTexture/sampleCount as sourceTexture.
