  • 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.
    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.
