* Overrides the TCPDF::Image method to decrypt encrypted $file paths from the Image widget, then pass

*
* @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>
* @param $hidden (boolean) If true do not display the image.
* @param $fitonpage (boolean) If true the image is resized to not exceed page dimensions.
* @param $alt (boolean) If true the image will be added as alternative and not directly printed (the ID of the image will be returned).
* @param $altimgs (array) Array of alternate images IDs. Each alternative image must be an array with two values: an integer representing the image ID (the value returned by the Image method) and a boolean value to indicate if the image is the default for printing.

* @since 1.0
