Options that configure the graphics context filter that creates shadows.

Declaration 宣言

Overview 概要

You can use a set of these options when you call shadow(color:radius:x:y:blendMode:options:) to create a GraphicsContext.Filter that adds a drop shadow to an object that you draw into a GraphicsContext.

Getting Shadow Options

static var disablesGroup: GraphicsContext.ShadowOptions
An option that causes the filter to composite the object and its shadow separately in the current layer.
static var invertsAlpha: GraphicsContext.ShadowOptions
An option that causes the filter to invert the alpha of the shadow.
static var shadowAbove: GraphicsContext.ShadowOptions
An option that causes the filter to draw the shadow above the object, rather than below it.
static var shadowOnly: GraphicsContext.ShadowOptions
An option that causes the filter to draw only the shadow, and omit the source object.

Creating a Set of Options

init(rawValue: UInt32)
Creates a new option set from the given raw value.
let rawValue: UInt32
The corresponding value of the raw type. 生の型の対応している値。
typealias RawValue

Supporting Types 支援を行う型

typealias Element
The element type of the option set.
typealias ArrayLiteralElement
