# CVPixelBufferGetExtendedPixels(_:_:_:_:_:)

Returns the amount of extended pixel padding in the pixel buffer.

## Declaration

```swift
func CVPixelBufferGetExtendedPixels(_ pixelBuffer: CVPixelBuffer, _ extraColumnsOnLeft: UnsafeMutablePointer<Int>?, _ extraColumnsOnRight: UnsafeMutablePointer<Int>?, _ extraRowsOnTop: UnsafeMutablePointer<Int>?, _ extraRowsOnBottom: UnsafeMutablePointer<Int>?)
```

## Parameters

- `pixelBuffer`: The pixel buffer whose extended pixel size you want to obtain.
- `extraColumnsOnLeft`: On output, the pixel row padding to the left. Pass NULL if you do not want this information.
- `extraColumnsOnRight`: On output, the pixel row padding to the right. Pass NULL if you do not want this information.
- `extraRowsOnTop`: On output, the pixel row padding to the top. Pass NULL if you do not want this information.
- `extraRowsOnBottom`: On output, the pixel row padding to the bottom. Pass NULL if you do not want this information.
