where Self: Sized + Message,

Available on crate feature CIImage only.

Setter for inputImage.

unsafe fn lightPosition(&self) -> Retained<CIVector>

where Self: Sized + Message,

Available on crate feature CIVector only.

The x and y position of the spotlight.

unsafe fn setLightPosition(&self, light_position: &CIVector)

where Self: Sized + Message,

Available on crate feature CIVector only.

Setter for lightPosition.

unsafe fn lightPointsAt(&self) -> Retained<CIVector>
