TYPES

public static final java.lang.String[] TYPES

A list of type identifiers for the Code39 barcode format

构造器详细资料

Code39Barcode

public Code39Barcode(java.lang.String data,
             boolean requiresChecksum)
              throws BarcodeException

Constructs a basic mode Code 39 barcode with the specified data and an optional checksum.

参数:

data - The data to encode

requiresChecksum - A flag indicating whether a checksum is required or not

抛出:

BarcodeException - If the data to be encoded is invalid

Code39Barcode

public Code39Barcode(java.lang.String data,
             boolean requiresChecksum,
             boolean extendedMode)
              throws BarcodeException

Constructs an extended mode Code 39 barcode with the specified data and an optional checksum. The extended mode encodes all 128 ASCII characters using two character pairs from the basic Code 39 character set. Note that most barcode scanners will need to be configured to accept extended Code 39.

参数:

data - The data to encode

requiresChecksum - A flag indicating whether a checksum is required or not

extendedMode - Puts the barcode into extended mode, where all 128 ASCII characters can be encoded

抛出:

BarcodeException - If the data to be encoded is invalid
