init

TypeScript
init(rawValue: _CoreFoundation_CFString): CMFormatDescription_Extensions_Value_ChromaLocation
Swift declaration
init(rawValue: CFString)

Creates a new instance with the specified raw value. If there is no value of the type that corresponds with the specified raw value, this initializer returns `nil`. For example: enum PaperSize: String { case A4, A5, Letter, Legal } print(PaperSize(rawValue: "Legal")) // Prints "Optional(PaperSize.Legal)" print(PaperSize(rawValue: "Tabloid")) // Prints "nil" - Parameter rawValue: The raw value to use for the new instance.

rawValue

TypeScript
getRawValue($self: CMFormatDescription_Extensions_Value_ChromaLocation): _CoreFoundation_CFString
Swift declaration
var rawValue: CFString

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"

rawValue

TypeScript
setRawValue($self: CMFormatDescription_Extensions_Value_ChromaLocation, value: _CoreFoundation_CFString): void
Swift declaration

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"
