Dear Monks: I am using Tk:GraphViz to display a graph and all is working fine. I would like to create a background image on the "Canvas" (GraphViz is derived from Canvas) but it is not working (image does not appear on canvas; Also no error messages) I can set a background color when creating the GraphViz widget though.

$gv = $frame->Scrolled(
        'GraphViz',

         -width=>600,
        -height=>600,
        -scrollbars => 'sw',
        -background => 'lightblue',
    )->pack(qw/-expand 1 -fill both -padx 10 -pady 5/);



my $img = $poe_main_window->Photo( -file => './test.png');
$gv->createImage(0,0,-image=>$img,-anchor=>'nw', -tags=>['img'],);
