Available on crate features CIFilter and CIFilterBuiltins only.

The protocol for the Hue/Saturation/Value Gradient filter.

Generates a color wheel that shows hues and saturations for a specified value.

Provided Methods

unsafe fn value(&self) -> c_float

where Self: Sized + Message,

The color value used to generate the color wheel.

unsafe fn setValue(&self, value: c_float)

where Self: Sized + Message,

Setter for value.

unsafe fn radius(&self) -> c_float

where Self: Sized + Message,

The radius of the color wheel in pixels.

unsafe fn setRadius(&self, radius: c_float)

where Self: Sized + Message,

Setter for radius.

unsafe fn softness(&self) -> c_float

where Self: Sized + Message,

The amount to smooth the hue angle to make it appear more continuous.

unsafe fn setSoftness(&self, softness: c_float)

where Self: Sized + Message,

Setter for softness.

unsafe fn dither(&self) -> c_float

where Self: Sized + Message,

The amount of dithered noise to add to the color wheel to avoid banding artifacts.

unsafe fn setDither(&self, dither: c_float)

where Self: Sized + Message,

Setter for dither.

unsafe fn colorSpace(&self) -> Option<Retained<CGColorSpace>>

where Self: Sized + Message,

Available on crate feature objc2-core-graphics only.

unsafe fn setColorSpace(&self, color_space: Option<&CGColorSpace>)

where Self: Sized + Message,

Available on crate feature objc2-core-graphics only.

Setter for colorSpace.
