方法详细资料

decode

public Result decode(BinaryBitmap image)
              throws NotFoundException,
                     ChecksumException,
                     FormatException

Locates and decodes a MaxiCode in an image.

指定者:

decode 在接口中 Reader

参数:

image - image of barcode to decode

返回:

a String representing the content encoded by the MaxiCode

抛出:

NotFoundException - if a MaxiCode cannot be found

FormatException - if a MaxiCode cannot be decoded

ChecksumException - if error correction fails

decode

public Result decode(BinaryBitmap image,
                     java.util.Map<DecodeHintType,?> hints)
              throws NotFoundException,
                     ChecksumException,
                     FormatException

从接口复制的说明: Reader

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.

指定者:

decode 在接口中 Reader

参数:

image - image of barcode to decode

hints - passed as a Map 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.

返回:

String which the barcode encodes

抛出:

NotFoundException - if no potential barcode is found

ChecksumException - if a potential barcode is found but does not pass its checksum

FormatException - if a potential barcode is found but format is invalid

reset

public void reset()

从接口复制的说明: Reader

Resets any internal state the implementation has after a decode, to prepare it for reuse.

指定者:

reset 在接口中 Reader
