pub unsafe static kCIContextPriorityRequestLow: &'static CIContextOptionAvailable on crate feature
CIContext only.Expand description
A Boolean value to control the priority Core Image context renders.
If this value is True, then rendering with the context from a background thread takes lower priority than other GPU usage from the main thread. This allows your app to perform Core Image rendering without disturbing the frame rate of UI animations.
