GraphicsContext.BlurOptions

struct · iOS 15.0+ · SDK 27.1

@frozen struct BlurOptions

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

dithersResult

TypeScript

get dithersResult(): GraphicsContext_BlurOptions

Swift declaration

static var dithersResult: GraphicsContext.BlurOptions { get }

An option that causes the filter to dither the result, to reduce banding.

opaque

TypeScript

get opaque(): GraphicsContext_BlurOptions

Swift declaration

static var opaque: GraphicsContext.BlurOptions { get }

An option that causes the filter to ensure the result is completely opaque. The filter ensure opacity by dividing each pixel by its alpha value. The result may be undefined if the input to the filter isn't also completely opaque.

init · iOS 15.0+

init

TypeScript

init(rawValue: number): GraphicsContext_BlurOptions

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_BlurOptions): 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"
