    // shadow( x, y, sigma, alpha, colour )
    // basically i dont get any sort of blurred shadow
    // x and y dont seem to do anything at all
    // sigma seems to be shadow size and not the amount of blur
    // alpha doesnt seem to do anything either
    shadow.Shadow( 10, 10, 0.5, new Percentage( 80 ), MagickColor.FromRgb( 127, 127, 127 ) ); // this makes the shadow size tiny
//    shadow.Shadow( 10, 10, 20, new Percentage( 80 ), MagickColor.FromRgb( 127, 127, 127 ) ); // this makes the shadow size bigger, but why its supposed to be the blur size
