	/// Implementations of this interface can decode an image of a barcode in some format into
	/// the String it encodes. For example, <seealso cref="com.google.zxing.qrcode.QRCodeReader"/> can
	/// decode a QR code. The decoder may optionally receive hints from the caller which may help
	/// it decode more quickly or accurately.
	/// 
	/// See <seealso cref="com.google.zxing.MultiFormatReader"/>, which attempts to determine what barcode
	/// format is present within the image as well, and then decodes it accordingly.
