	 func Decode(r io.Reader) (image.Image, error)
		Decode reads a JPEG image from r and returns it as an image.Image.
	 func DecodeConfig(r io.Reader) (image.Config, error)
		DecodeConfig returns the color model and dimensions of a JPEG image without
		decoding the entire image.
	const DefaultQuality = 75
		DefaultQuality is the default quality encoding parameter.
	 func Encode(w io.Writer, m image.Image, o *Options) error
		Encode writes the Image m to w in JPEG 4:2:0 baseline format with the given
