| 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. Reader objects
accept a BinaryBitmap and attempt to decode it. |
| 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. This could have
been due to a mis-detection. |
| GDLuminanceSource |
This class is used to help decode images from files which arrive as GD Resource
It does not support rotation. |
| IMagickLuminanceSource |
This class is used to help decode images from files which arrive as GD Resource
It does not support rotation. |
| LuminanceSource |
The purpose of this class hierarchy is to abstract different bitmap implementations across
platforms into a standard interface for requesting greyscale luminance values. The interface
only provides immutable methods; therefore crop and rotation create copies. This is to ensure
that one Reader does not modify the original luminance source and leave it in an unknown state
for other Readers in the chain. |
| NotFoundException |
Thrown when a barcode was not found in the image. It might have been
partially detected but could not be confirmed. |
| 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. This can be used to exclude
superfluous pixels around the perimeter and speed up decoding. |
| QrReader |
|
| ReaderException |
The general exception class throw when something goes wrong during decoding of a barcode. |
| Result |
<p>Encapsulates the result of decoding a barcode within an image.</p> |
| ResultPoint |
<p>Encapsulates a point of interest in an image containing a barcode. Typically, this
would be the location of a finder pattern or the corner of the barcode, for example.</p> |
| RGBLuminanceSource |
This class is used to help decode images from files which arrive as RGB data from
an ARGB pixel array. It does not support rotation. |
