# init(frameWidth:frameHeight:scaleFactor:inputType:usePrecomputedFlow:qualityPrioritization:revision:)

Creates a new super-resolution scaler processor configuration.

## Declaration

```swift
init?(frameWidth: Int, frameHeight: Int, scaleFactor: Int, inputType: VTSuperResolutionScalerConfiguration.InputType, usePrecomputedFlow: Bool, qualityPrioritization: VTSuperResolutionScalerConfiguration.QualityPrioritization, revision: VTSuperResolutionScalerConfiguration.Revision)
```

## Parameters

- `frameWidth`: Width of source frame in pixels. With VTSuperResolutionScalerConfigurationInputTypeVideo, maximum width is 1920 on macOS and 1440 on iOS. With VTSuperResolutionScalerConfigurationInputTypeImage, maximum width is 1920.
- `frameHeight`: Height of source frame in pixels. With VTSuperResolutionScalerConfigurationInputTypeVideo, maximum height is 1080. With VTSuperResolutionScalerConfigurationInputTypeImage, maximum height is 1920 on macOS and 1080 on iOS.
- `scaleFactor`: Indicates the scale factor between input and output.
- `inputType`: Indicates the type of input, either video or image.
- `usePrecomputedFlow`: Boolean value to indicate that you provide optical flow; if false, this configuration computes the optical flow on the fly.
- `qualityPrioritization`: A level you use to prioritize quality or performance; for more information about supported levels, see doc://com.apple.videotoolbox/documentation/VideoToolbox/VTSuperResolutionScalerConfiguration/QualityPrioritization-swift.enum.
- `revision`: The specific algorithm or configuration revision you use to perform the request.

## Discussion

Discussion This processor increases resolution of an image or video. Returns nil if dimensions are out of range or revision is unsupported.
