| Interface | Description |
|---|---|
| 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 | Description |
|---|---|
| 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.
|
| Dimension |
Simply encapsulates a width and height.
|
| HtmlAssetTranslator |
A utility which auto-translates the English-language text in a directory of HTML documents using
Google Translate.
|
| 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.
|
| 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.
|
| Result |
Encapsulates the result of decoding a barcode within an image.
|
| ResultPoint |
Encapsulates a point of interest in an image containing a barcode.
|
| RGBLuminanceSource |
This class is used to help decode images from files which arrive as RGB data from
an ARGB pixel array.
|
| StringsResourceTranslator |
A utility which auto-translates English strings in Android string resources using
Google Translate.
|
| Enum | Description |
|---|---|
| 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 | Description |
|---|---|
| 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.
