Available on crate features CIFilter and CIFilterBuiltins only.

The protocol for the Tone Map Headroom filter.

Apply a global tone curve to an image that reduces colors from a source headroom value to a target headroom value.

Provided Methods

unsafe fn inputImage(&self) -> Option<Retained<CIImage>>

where Self: Sized + Message,

Available on crate feature CIImage only.

Specifies input image with an optional content headroom property.

unsafe fn setInputImage(&self, input_image: Option<&CIImage>)

where Self: Sized + Message,

Available on crate feature CIImage only.

Setter for inputImage.

unsafe fn sourceHeadroom(&self) -> c_float

where Self: Sized + Message,

If non-nil, this overrides the headroom property of the input image.

unsafe fn setSourceHeadroom(&self, source_headroom: c_float)

where Self: Sized + Message,

Setter for sourceHeadroom.

unsafe fn targetHeadroom(&self) -> c_float

where Self: Sized + Message,

Specifies the target headroom of the output image.

unsafe fn setTargetHeadroom(&self, target_headroom: c_float)

where Self: Sized + Message,

Setter for targetHeadroom.
