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

Declaration

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 Qualityprioritization Swift.enum.

• revision:

  The specific algorithm or configuration revision you use to perform the request.

Discussion

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