Trait CIGammaAdjust

    // Provided methods
    unsafe fn inputImage(&self) -> Option<Retained<CIImage>>
       where Self: Sized + Message { ... }

Available on crate features CIFilter and CIFilterBuiltins only.

The protocol for the Gamma Adjust filter.

Adjusts midtone brightness. This filter is typically used to compensate for nonlinear effects of displays. Adjusting the gamma effectively changes the slope of the transition between black and white.

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 power(&self) -> c_float

where Self: Sized + Message,

A gamma value to use to correct image brightness. The larger the value, the darker the result.

unsafe fn setPower(&self, power: c_float)

where Self: Sized + Message,

Setter for power.
