# init(size:pixelFormat:)

Returns a new multiplane pixel buffer with a size that you specify.

## Declaration

```swift
init(size: vImage.Size, pixelFormat: Format.Type = Format.self)
```

## Parameters

- `size`: The width and height of the buffer.
- `pixelFormat`: The pixel format of the buffer.

## Discussion

Discussion This initializer allocates but doesn’t initialize the pixel buffer’s memory. That is, the operation doesn’t guarantee that all pixel values are zero.
