Type members

• init(T)

  Creates an opaque grayscale-alpha color.

• init(T, T)

  Creates a grayscale-alpha color.

• static func pack([`Self`], as: PNG.Format, indexer: ([(r: UInt8, g: UInt8, b: UInt8, a: UInt8)]) -> (Aggregate) -> Int) -> [UInt8]

  Packs an array of grayscale-alpha pixels to an image data storage buffer.

• static func unpack([UInt8], of: PNG.Format, deindexer: ([(r: UInt8, g: UInt8, b: UInt8, a: UInt8)]) -> (Int) -> Aggregate) -> [`Self`]

  Unpacks an image data storage buffer to an array of grayscale-alpha pixels.

Instance members

• var premultiplied: `Self`

  The color obtained by premultiplying the gray component of this color with its alpha channel.

• var straightened: `Self`

  The color obtained by straightening the gray component of this color according to its alpha channel.

• func premultiplied<U>(as: U.Type) -> PNG.VA<T>

  The color obtained by premultiplying the gray component of this color with its alpha channel, performing the premultiplication in the given integer type.

• func straightened<U>(as: U.Type) -> PNG.VA<T>

  The color obtained by straightening the gray component of this color according to its alpha channel, performing the straightening in the given integer type.
