Code 39 barcodes can be generated using either fonts or software such as embedded objects.\u00a0When using a font, the text should include the start\/stop * character at either end of the barcode, but software generated barcodes will often add the * characters automatically. This can sometimes result in barcodes with 2 * characters at either end.<\/p>\n
e.g. **12345** rather than *12345*<\/p>\n
This can be identified in a barcode by checking to see if the first 10 black bars conform to the pattern:<\/p>\n
NNWWNNNWWN where N = narrow and W = wide.<\/p>\n
Such a barcode doesn’t conform to the Code 39 specification, but can be read by the toolkit using the following settings:<\/p>\n
Code39NeedStartStop = false or 0
\nPattern = “^\\*\\*[^\\*]+\\*\\*$”<\/p>\n
Note that the barcode returned by the toolkit will contain the leading and trailing * characters.<\/p>\n","protected":false},"excerpt":{"rendered":"
