Available on crate features CIFilter and CIFilterBuiltins only.

The protocol for the Line Overlay filter.

Creates a sketch that outlines the edges of an image in black, leaving the non-outlined portions of the image transparent. The result has alpha and is rendered in black, so it won’t look like much until you render it over another image using source over compositing.

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 NRNoiseLevel(&self) -> c_float

where Self: Sized + Message,

The noise level of the image (used with camera data) that gets removed before tracing the edges of the image. Increasing the noise level helps to clean up the traced edges of the image.

unsafe fn setNRNoiseLevel(&self, nr_noise_level: c_float)

where Self: Sized + Message,

Setter for NRNoiseLevel.

unsafe fn NRSharpness(&self) -> c_float

where Self: Sized + Message,

The amount of sharpening done when removing noise in the image before tracing the edges of the image. This improves the edge acquisition.

unsafe fn setNRSharpness(&self, nr_sharpness: c_float)

where Self: Sized + Message,

Setter for NRSharpness.

unsafe fn edgeIntensity(&self) -> c_float

where Self: Sized + Message,

The accentuation factor of the Sobel gradient information when tracing the edges of the image. Higher values find more edges, although typically a low value (such as 1.0) is used.

unsafe fn setEdgeIntensity(&self, edge_intensity: c_float)

where Self: Sized + Message,

Setter for edgeIntensity.

unsafe fn threshold(&self) -> c_float

where Self: Sized + Message,

This value determines edge visibility. Larger values thin out the edges.

unsafe fn setThreshold(&self, threshold: c_float)

where Self: Sized + Message,

Setter for threshold.

unsafe fn contrast(&self) -> c_float

where Self: Sized + Message,

The amount of anti-aliasing to use on the edges produced by this filter. Higher values produce higher contrast edges (they are less anti-aliased).

unsafe fn setContrast(&self, contrast: c_float)

where Self: Sized + Message,

Setter for contrast.
