Package com.google.zxing

Interface Summary

Reader	Implementations of this interface can decode an image of a barcode in some format into the String it encodes.
ResultPointCallback	Callback which is invoked when a possible result point (significant point in the barcode image such as a corner) is found.
Writer	The base class for all objects which encode/generate a barcode image.

Class Summary

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.
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.
Result	Encapsulates the result of decoding a barcode within an image.
ResultPoint	Encapsulates a point of interest in an image containing a barcode.

Enum Summary

BarcodeFormat	Enumerates barcode formats known to this package.
DecodeHintType	Encapsulates a type of hint that a caller may pass to a barcode reader to help it more quickly or accurately decode it.
EncodeHintType	These are a set of hints that you may pass to Writers to specify their behavior.
ResultMetadataType	Represents some type of metadata about the result of the decoding that the decoder wishes to communicate back to the caller.

Exception Summary

ChecksumException	Thrown when a barcode was successfully detected and decoded, but was not returned because its checksum feature failed.
FormatException	Thrown when a barcode was successfully detected, but some aspect of the content did not conform to the barcode's format rules.
NotFoundException	Thrown when a barcode was not found in the image.
ReaderException	The general exception class throw when something goes wrong during decoding of a barcode.
WriterException	A base class which covers the range of exceptions which may occur when encoding a barcode using the Writer framework.
