GraphicsContext.ShadowOptions

struct · iOS 15.0+ · SDK 27.1

@frozen struct ShadowOptions

Options that configure the graphics context filter that creates shadows. You can use a set of these options when you call ``Filter/shadow(color:radius:x:y:blendMode:options:)`` to create a ``Filter`` that adds a drop shadow to an object that you draw into a ``GraphicsContext``.

shadowOnly

TypeScript

get shadowOnly(): GraphicsContext_ShadowOptions

Swift declaration

static var shadowOnly: GraphicsContext.ShadowOptions { get }

An option that causes the filter to draw only the shadow, and omit the source object.

get · iOS 15.0+

shadowAbove

TypeScript

get shadowAbove(): GraphicsContext_ShadowOptions

Swift declaration

static var shadowAbove: GraphicsContext.ShadowOptions { get }

An option that causes the filter to draw the shadow above the object, rather than below it.

get · iOS 15.0+

invertsAlpha

TypeScript

get invertsAlpha(): GraphicsContext_ShadowOptions

Swift declaration

static var invertsAlpha: GraphicsContext.ShadowOptions { get }

An option that causes the filter to invert the alpha of the shadow. You can create an "inner shadow" effect by combining this option with ``shadowAbove`` and using the ``GraphicsContext/BlendMode-swift.struct/sourceAtop`` blend mode.

disablesGroup

TypeScript

get disablesGroup(): GraphicsContext_ShadowOptions

Swift declaration

static var disablesGroup: GraphicsContext.ShadowOptions { get }

An option that causes the filter to composite the object and its shadow separately in the current layer.

init · iOS 15.0+

init

TypeScript

init(rawValue: number): GraphicsContext_ShadowOptions

Swift declaration

init(rawValue: UInt32)

Creates a new option set from the given raw value. This initializer always succeeds, even if the value passed as `rawValue` exceeds the static properties declared as part of the option set. This example creates an instance of `ShippingOptions` with a raw value beyond the highest element, with a bit mask that effectively contains all the declared static members. let extraOptions = ShippingOptions(rawValue: 255) print(extraOptions.isStrictSuperset(of: .all)) // Prints "true" - Parameter rawValue: The raw value of the option set to create. Each bit of `rawValue` potentially represents an element of the option set, though raw values may include bits that are not defined as distinct values of the `OptionSet` type.

rawValue

TypeScript

getRawValue($self: GraphicsContext_ShadowOptions): number

Swift declaration

let rawValue: UInt32

The corresponding value of the raw type. A new instance initialized with `rawValue` will be equivalent to this instance. For example: enum PaperSize: String { case A4, A5, Letter, Legal } let selectedSize = PaperSize.Letter print(selectedSize.rawValue) // Prints "Letter" print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!) // Prints "true"
