ZXing.Reader Unit

Implementations of this interface can decode an image of a barcode in some format into the String it encodes. For example, 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 MultiFormatReader , which attempts to determine what barcode format is present within the image as well, and then decodes it accordingly.
