Class Summary

Class

Description

BitArray

A simple, fast array of bits, represented compactly by an array of ints internally.

BitMatrix

Represents a 2D matrix of bits.

BitSource

This provides an easy abstraction to read bits at a time from a sequence of bytes, where the number of bits read is not often a multiple of 8.

DecoderResult

Encapsulates the result of decoding a matrix of bits.

DefaultGridSampler

DetectorResult

Encapsulates the result of detecting a barcode in an image.

GlobalHistogramBinarizer

This Binarizer implementation uses the old ZXing global histogram approach.

GridSampler

Implementations of this class can, given locations of finder patterns for a QR code in an image, sample the right points in the image to reconstruct the QR code, accounting for perspective distortion.

HybridBinarizer

This class implements a local thresholding algorithm, which while slower than the GlobalHistogramBinarizer, is fairly efficient for what it does.

PerspectiveTransform

This class implements a perspective transform in two dimensions.

StringUtils

Common string-related functions.
Enum Summary

Enum

Description

CharacterSetECI

Encapsulates a Character Set ECI, according to "Extended Channel Interpretations" 5.3.1.1 of ISO 18004.
