Available on crate features CIFilter and CIFilterBuiltins only.

The protocol for the Signed Distance Gradient From Red Mask filter.

Produces an infinite image where the red channel contains the distance in pixels from each pixel to the mask.

Provided Methods

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

where Self: Sized + Message,

Available on crate feature CIImage only.

The input image whose red channel defines a mask. If the red channel pixel value is greater than 0.5 then the point is considered in the mask and output pixel will be a value between zero and negative one. Otherwise the output pixel will be a value between zero and one.

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

where Self: Sized + Message,

Available on crate feature CIImage only.

Setter for inputImage.

unsafe fn maximumDistance(&self) -> c_float

where Self: Sized + Message,

Determines the maximum distance to the mask that can be measured. Distances between zero and the maximum will be normalized to negative one and one.

unsafe fn setMaximumDistance(&self, maximum_distance: c_float)

where Self: Sized + Message,

Setter for maximumDistance.
