  • Class
    Description
    BarcodeFormat
    Enumerates barcode formats known to this package.
    Binarizer
    This class hierarchy provides a set of methods to convert luminance data to 1 bit data.
    BinaryBitmap
    This class is the core bitmap class used by ZXing to represent 1 bit data.
    ChecksumException
    Thrown when a barcode was successfully detected and decoded, but was not returned because its checksum feature failed.
    DecodeHintType
    Encapsulates a type of hint that a caller may pass to a barcode reader to help it more quickly or accurately decode it.
    Dimension
    Simply encapsulates a width and height.
    EncodeHintType
    These are a set of hints that you may pass to Writers to specify their behavior.
    FormatException
    Thrown when a barcode was successfully detected, but some aspect of the content did not conform to the barcode's format rules.
    GrayscaleLuminanceSource
    This class is used to help decode images from files which arrive as a grayscale pixel array.
    InvertedLuminanceSource
    A wrapper implementation of LuminanceSource which inverts the luminances it returns -- black becomes white and vice versa, and each value becomes (255-value).
    LuminanceSource
    The purpose of this class hierarchy is to abstract different bitmap implementations across platforms into a standard interface for requesting greyscale luminance values.
    MultiFormatReader
    MultiFormatReader is a convenience class and the main entry point into the library for most uses.
    MultiFormatWriter
    This is a factory class which finds the appropriate Writer subclass for the BarcodeFormat requested and encodes the barcode with the supplied contents.
    NotFoundException
    Thrown when a barcode was not found in the image.
    PlanarYUVLuminanceSource
    This object extends LuminanceSource around an array of YUV data returned from the camera driver, with the option to crop to a rectangle within the full data.
    Reader
    Implementations of this interface can decode an image of a barcode in some format into the String it encodes.
    ReaderException
    The general exception class throw when something goes wrong during decoding of a barcode.
    Result
    Encapsulates the result of decoding a barcode within an image.
    ResultMetadataType
    Represents some type of metadata about the result of the decoding that the decoder wishes to communicate back to the caller.
    ResultPoint
    Encapsulates a point of interest in an image containing a barcode.
    ResultPointCallback
    Callback which is invoked when a possible result point (significant point in the barcode image such as a corner) is found.
    RGBLuminanceSource
    This class is used to help decode images from files which arrive as RGB data from an ARGB pixel array.
    Writer
    The base class for all objects which encode/generate a barcode image.
    WriterException
    A base class which covers the range of exceptions which may occur when encoding a barcode using the Writer framework.
