* @param array $style array of options:<ul><li>string $style['position'] barcode position inside the specified width: L = left (default for LTR); C = center; R = right (default for RTL); S = stretch</li><li>boolean $style['border'] if true prints a border around the barcode</li><li>int $style['padding'] padding to leave around the barcode in user units</li><li>array $style['fgcolor'] color array for bars and text</li><li>mixed $style['bgcolor'] color array for background or false for transparent</li><li>boolean $style["text"] boolean if true prints text below the barcode</li><li>string $style['font'] font name for text</li><li>int $style['fontsize'] font size for text</li><li>int $style['stretchtext']: 0 = disabled; 1 = horizontal scaling only if necessary; 2 = forced horizontal scaling; 3 = character spacing only if necessary; 4 = forced character spacing</li></ul>
* @param string $align Indicates the alignment of the pointer next to barcode insertion relative to barcode height. The value can be:<ul><li>T: top-right for LTR or top-left for RTL</li><li>M: middle-right for LTR or middle-left for RTL</li><li>B: bottom-right for LTR or bottom-left for RTL</li><li>N: next line</li></ul>
