Gmagick Gmagick::raiseimage( $width, $height, $x, $y, $raise )

- $x: This parameter stores the value of the x-coordinate.
- $y: This parameter stores the value of the y-coordinate.
- $raise: This parameter stores the value of the raise where value other than zero creates a 3-D raise effect, otherwise it has a lowered effect.
