Dear bretheren, I'm am asking you help because I have this #$!%&** client (oops, need to do more prayers now) who does not like the gauges Tk::Gauge provides. He is able to use printscreen and photoshop and he found some very flashy dials and he is making me do all that I can to use these awful things. My question is. If I save this dial to like a png or gif, how can I use the Tk::Gauge gauge to be placed over it and be transparent so that the needle moves while the picture underneath shows. Or should I use some other module. Canvas? Or gd with tk, or what?

#!/usr/bin/perl

$mw->title("map voltmeter");
$mw->optionAdd("*font", "*utf-8");

my $Vdc;

$Vdc = 125;
