	/**
	 * Embedd a Scalable Vector Graphics (SVG) image.
	 * NOTE: SVG standard is not yet fully implemented, use the setRasterizeVectorImages() method to enable/disable rasterization of vector images using ImageMagick library.
	 * @param string $file Name of the SVG file or a '@' character followed by the SVG data string.
	 * @param float|null $x Abscissa of the upper-left corner.
	 * @param float|null $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 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:
T: top-right for LTR or top-left for RTL
M: middle-right for LTR or middle-left for RTL
B: bottom-right for LTR or bottom-left for RTL
N: next line
 If the alignment is an empty string, then the pointer will be restored on the starting SVG position.
	 * @param string $palign Allows to center or align the image on the current line. Possible values are:
L : left align
C : center
R : right align
'' : empty string : left for LTR or right for RTL
	 * @param mixed $border Indicates if borders must be drawn around the cell. The value can be a number:
0: no border (default)
1: frame
 or a string containing some or all of the following characters (in any order):
L: left
T: top
R: right
B: bottom
 or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0)))
	 * @param boolean $fitonpage if true the image is resized to not exceed page dimensions.
