|
|
* ### Input Data Format ###
|
|
*
|
|
* The *Code 39* specification defines 43 characters, consisting of upper
|
|
* case letters (A-Z), decimal digits (0-9), space, and several special
|
|
* characters (-.$/+%). The BarcodeCode39 validator will also accept
|
|
* lower case letters (a-z). The encoder will automatically upshift
|
|
* any lower case letters prior to encoding.
|
|
*
|
|
* For full ASCII support see BarcodeCode39Ext.
|
|
*
|
|
*
|
|
* ### Checksum Property ###
|
|
*
|
|
* If the *checksum* property is *true*, a modulo 43 check digit will be
|
|
* automatically generated and appended to input data before encoding.
|
|
* By default, the check digit will not be generated.
|
|
*
|
|
* See setChecksum().
|
|
*
|
|
*
|
|
* ### Show Text Property ###
|
|
*
|
|
* If the *Show Text* property is *true*, the input data will be printed
|
|
* below the barcode. By default, the data will not be printed.
|
|
*
|
|
* See setShowText().
|
|
