how can I use this using perl and goo::canvas? please see the documentation: http://library.gnome.org/devel/goocanvas/unstable/goocanvas-goocanvasitem.html#goo-canvas-item-get-simple-transform i have tried the following.

my $x;
my $y;
my $scale;
my $angle;

$canvasitem->get_simple_transform($x,$y,$scale,$angle);
[download]

and

print $canvasitem->get_simple_transform;
[download]

all of this gives me an error, "something is very broken"
