 /**
  * Print 2D Barcode.
  * @param $code (string) code to print

  * @param $x (int) x position in user units
  * @param $y (int) y position in user units
  * @param $w (int) width in user units
  * @param $h (int) height in user units
  * @param $style (array) array of options:<ul>
  * <li>boolean $style['border'] if true prints a border around the barcode</li>
  * <li>int $style['padding'] padding to leave around the barcode in barcode units (set to 'auto' for automatic padding)</li>
  * <li>int $style['hpadding'] horizontal padding in barcode units (set to 'auto' for automatic padding)</li>
  * <li>int $style['vpadding'] vertical padding in barcode units (set to 'auto' for automatic padding)</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>string $style['position'] barcode position on the page: L = left margin; C = center; R = right margin; S = stretch</li><li>$style['module_width'] width of a single module in points</li>
  * <li>$style['module_height'] height of a single module in points</li></ul>
  * @param $align (string) 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>
  * @param $distort (boolean) if true distort the barcode to fit width and height, otherwise preserve aspect ratio
