Instance members

• var premultiplied: `Self`

  The color obtained by premultiplying the red, green, and blue components of this color with its alpha channel.

• var straightened: `Self`

  The color obtained by straightening the red, green, and blue components of this color according to its alpha channel.

• var va: PNG.VA<T>

  The grayscale-alpha color obtained by discarding the green and blue components of this color.

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

  The color obtained by premultiplying the red, green, and blue components of this color with its alpha channel, performing the premultiplication in the given integer type.

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

  The color obtained by straightening the red, green, and blue components of this color according to its alpha channel, performing the straightening in the given integer type.
