You already have the image as a pie so why not just overlay a background-coloured circle on the middle?

I can draw a circle separately. Here's the separate code. I use GD::Simple 


#!/usr/bin/perl 
use CGI ':standard';
use strict;
use warnings;
use GD::Simple;
 
# create a new image (width, height)
my $img = GD::Simple->new(200, 100);
 

$img->bgcolor('white');
$img->fgcolor('blue');
$img->moveTo(60, 50);    # (x, y)
$img->ellipse(80, 80);

binmode STDOUT;
print "Content-type: image/png\n\n";
print $img->png;

How can I insert it to the Pie chart code... Can you help me?

Can I use like this? 


my $img = (GD::Simple->new(200, 100),
       GD::Graph::pie->new(500, 600));
