getPattern()
The getPattern() function returns a pattern string consisting of zeros and ones which represent the bars and spaces of the barcode. For the 4-State clocked codes the Pattern string consists of the characters “0”, “1”, “2” and “3”, representing the four bar types present in these codes (short, long up, long down, and long both).
