Methods
getHue(_:saturation:brightness:alpha:)
Returns the components that form the color in the HSB color space.
public func getHue(_ hue: UnsafeMutablePointer<Double>?,
saturation: UnsafeMutablePointer<Double>?,
brightness: UnsafeMutablePointer<Double>?,
alpha: UnsafeMutablePointer<Double>?) -> Bool
If the color is in a compatible color space, it converts into the HSB color space, and its components return to your application. If the color isn’t in a compatible color space, the parameters don’t change.
getRed(_:green:blue:alpha:)
Returns the components that form the color in the RGB color space.
public func getRed(_ red: UnsafeMutablePointer<Double>?,
green: UnsafeMutablePointer<Double>?,
blue: UnsafeMutablePointer<Double>?,
alpha: UnsafeMutablePointer<Double>?) -> Bool
If the color is in a compatible color space, it converts into RGB format and its components return to your application. If the color isn’t in a compatible color space, the parameters don’t change.
getWhite(_:alpha:)
Returns the grayscale components of the color.
public func getWhite(_ white: UnsafeMutablePointer<Double>?,
alpha: UnsafeMutablePointer<Double>?) -> Bool
If the color is in a compatible color space, it converts into grayscale format and its returned to your application. If the color isn’t in a compatible color space, the parameters don’t change.
resolvedColor(with:)
Returns the version of the current color that results from the specified traits.
public func resolvedColor(with traitCollection: TraitCollection) -> Color
hash(into:)
public func hash(into hasher: inout Hasher)
