Expand description

The protocol for the Tone Curve filter.

Adjusts tone response of the R, G, and B channels of an image. The input points are five x,y values that are interpolated using a spline curve. The curve is applied in a perceptual (gamma 2) version of the working space.

Provided Methods§

unsafe fn inputImage(&self) -> Option<Retained<CIImage>>
where Self: Sized + Message,

Available on crate feature CIImage only.

The image to use as an input for the effect.

unsafe fn setInputImage(&self, input_image: Option<&CIImage>)
where Self: Sized + Message,

Available on crate feature CIImage only.

Setter for inputImage.

unsafe fn point0(&self) -> CGPoint
where Self: Sized + Message,

Available on crate feature objc2-core-foundation only.

A vector containing the position of the first point of the tone curve.

unsafe fn setPoint0(&self, point0: CGPoint)
where Self: Sized + Message,

Available on crate feature objc2-core-foundation only.

Setter for point0.

unsafe fn point1(&self) -> CGPoint
where Self: Sized + Message,

where Self: Sized + Message,

Available on crate feature objc2-core-foundation only.

Setter for point4.

unsafe fn extrapolate(&self) -> bool
where Self: Sized + Message,

If true, then the color effect will be extrapolated if the input image contains RGB component values outside the range 0.0 to 1.0.

unsafe fn setExtrapolate(&self, extrapolate: bool)
where Self: Sized + Message,

Setter for extrapolate.
