  * Overrides the TCPDF::Image method to decrypt encrypted $file paths from the Image widget, then pass
  * them to the normal TCPDF::Image along with all of the other (unmodified) parameters.
  *
  * @param string $file    Name of the file containing the image.
  * @param float  $x       Abscissa of the upper-left corner.
  * @param float  $y       Ordinate of the upper-left corner.
  * @param float  $w       Width of the image in the page. If not specified or equal to zero, it is automatically calculated.
  * @param float  $h       Height of the image in the page. If not specified or equal to zero, it is automatically calculated.
  * @param string $type    Image format. Possible values are (case insensitive): JPEG and PNG (whitout GD library) and all images supported by GD: GD, GD2, GD2PART, GIF, JPEG, PNG, BMP, XBM, XPM;. If not specified, the type is inferred from the file extension.
  * @param mixed  $link    URL or identifier returned by AddLink().
  * @param string $align   Indicates the alignment of the pointer next to image insertion relative to image 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 bool   $resize  If true resize (reduce) the image to fit $w and $h (requires GD library).
  * @param int    $dpi     dot-per-inch resolution used on resize
  * @param string $palign  Allows to center or align the image on the current line. Possible values are:<ul><li>L : left align</li><li>C : center</li><li>R : right align</li><li>'' : empty string : left for LTR or right for RTL</li></ul>
  * @param bool   $ismask  true if this image is a mask, false otherwise
  * @param mixed  $imgmask image object returned by this function or false
  * @param mixed  $border  Indicates if borders must be drawn around the image. The value can be either a number:<ul><li>0: no border (default)</li><li>1: frame</li></ul>or a string containing some or all of the following characters (in any order):<ul><li>L: left</li><li>T: top</li><li>R: right</li><li>B: bottom</li></ul>
