# renderTransform

A transform to apply to the source image.

```
var renderTransform: CGAffineTransform { get }
```

## Discussion

The transform to apply to the source image incorporating the [`renderScale`](/documentation/AVFoundation/AVVideoCompositionRenderContext/renderScale), [`pixelAspectRatio`](/documentation/AVFoundation/AVVideoCompositionRenderContext/pixelAspectRatio), and [`edgeWidths`](/documentation/AVFoundation/AVVideoCompositionRenderContext/edgeWidths).

The coordinate system origin is the top left corner of the buffer.
