Implements decoding of the EAN-13 format.
ZXing.OneD.OneDReader.TOneDReader
ZXing.OneD.UPCEANReader.TUPCEANReader
ZXing.OneD.EAN13Reader.TEAN13Reader
The TEAN13Reader type exposes the following members.
| Name | Description | |
|---|---|---|
 | G_PATTERNS | "Even", or "G" patterns used to encode UPC/EAN digits. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
 | INTEGER_MATH_SHIFT | (Inherited from ZXing.OneD.OneDReader.TOneDReader .) |
| L_PATTERNS | (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| MAX_AVG_VARIANCE | (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| MAX_INDIVIDUAL_VARIANCE | (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| MIDDLE_PATTERN | Pattern marking the middle of a UPC/EAN pattern, separating the two halves. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| START_END_PATTERN | Start/end guard pattern. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| Name | Description | |
|---|---|---|
 | Create | Initializes a new instance of the TUPCEANReader class. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| Destroy | (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| Name | Description | |
|---|---|---|
| BarcodeFormat | Get the format of this decoder. The 1D format. (Overrides ZXing.OneD.UPCEANReader.TUPCEANReader.BarcodeFormat .) |
| DecodeMiddle | Subclasses override this to decode the portion of a barcode between the start and end guard patterns. (Overrides ZXing.OneD.UPCEANReader.TUPCEANReader.DecodeMiddle .) |
| DoDecodeRow | Like decodeRow(int, BitArray, java.util.Map), but allows caller to inform method about where the UPC/EAN start pattern is found. This allows this to be computed once and reused across many implementations. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
 | RecordPatternInReverse | Records the pattern in reverse. (Inherited from ZXing.OneD.OneDReader.TOneDReader .) |
| checkChecksum | (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| decode | Overloaded. Locates and decodes a barcode in some format within an image. This method also accepts hints, each possibly associated to some data, which may help the implementation decode. Note that we don't try rotation without the try harder flag, even if rotation was supported. (Inherited from ZXing.OneD.OneDReader.TOneDReader .) |
 | decodeDigit | Attempts to decode a single UPC/EAN-encoded digit. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| decodeEnd | Decodes the end. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| decodeRow | Attempts to decode a one-dimensional barcode format given a single row of an image. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| findGuardPattern | Overloaded. (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| findStartGuardPattern | (Inherited from ZXing.OneD.UPCEANReader.TUPCEANReader .) |
| patternMatchVariance | Determines how closely a set of observed counts of runs of black/white values matches a given target pattern. This is reported as the ratio of the total variance from the expected pattern proportions across all pattern elements, to the length of the pattern. (Inherited from ZXing.OneD.OneDReader.TOneDReader .) |
| recordPattern | Records the size of successive runs of white and black pixels in a row, starting at a given point. The values are recorded in the given array, and the number of runs recorded is equal to the size of the array. If the row starts on a white pixel at the given start point, then the first count recorded is the run of white pixels starting from that point; likewise it is the count of a run of black pixels if the row begin on a black pixels at that point. (Inherited from ZXing.OneD.OneDReader.TOneDReader .) |
| reset | Resets any internal state the implementation has after a decode, to prepare it for reuse. (Inherited from ZXing.OneD.OneDReader.TOneDReader .) |
