Result |
decode(BinaryBitmap image)
Locates and decodes a barcode in some format within an image. |
|
Result |
decode(BinaryBitmap image,
Hashtable hints)
Locates and decodes a barcode in some format within an image. |
|
Result |
decodeRow(int rowNumber,
BitArray row,
int[] startGuardRange)
Like OneDReader.decodeRow(int, BitArray, java.util.Hashtable), but
allows caller to inform method about where the UPC/EAN start pattern is
found. |
|
Result |
decodeRow(int rowNumber,
BitArray row,
Hashtable hints)
Attempts to decode a one-dimensional barcode format given a single row of an image. |

public Result decodeRow(int rowNumber,
BitArray row,
int[] startGuardRange)
throws ReaderException
UPCEANReaderLike OneDReader.decodeRow(int, BitArray, java.util.Hashtable), 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.
decodeRow in interface UPCEANReaderReaderException
public Result decodeRow(int rowNumber,
BitArray row,
Hashtable hints)
throws ReaderException
OneDReaderAttempts to decode a one-dimensional barcode format given a single row of an image.
decodeRow in interface OneDReaderrowNumber - row number from top of the rowrow - the black/white pixel data of the rowhints - decode hints
Result containing encoded string and start/end of barcode
ReaderException - if an error occurs or barcode cannot be found
public Result decode(BinaryBitmap image)
throws ReaderException
Reader
decode in interface Readerimage - image of barcode to decode
ReaderException - if the barcode cannot be located or decoded for any reason
public Result decode(BinaryBitmap image,
Hashtable hints)
throws ReaderException
Reader
decode in interface Readerimage - image of barcode to decodehints - passed as a Hashtable from DecodeHintType
to arbitrary data. The
meaning of the data depends upon the hint type. The implementation may or may not do
anything with these hints.
ReaderException - if the barcode cannot be located or decoded for any reason
