maximumPixelCount(forSpatialScaleFactor:)
The maximum total number of pixels in the source frame for a given spatial scale factor.
Declaration
class func maximumPixelCount(forSpatialScaleFactor spatialScaleFactor: Int) -> IntDiscussion
The product of frameWidth and frameHeight must be less than or equal to this value. Use in conjunction with maximumDimension(forSpatialScaleFactor:) to determine valid frame dimensions. Pass 1 for spatialScaleFactor when using the processor for temporal interpolation without spatial scaling. Returns 0 if an unsupported scale factor is provided.
