Re: CGI Graphics on Internet Information Server

The following test script (say, trygd.pl) should work on Apache + ActiveState + Win32 (sorry, not really what you wanted, though):

#! /usr/local/bin/perl -w
use strict;
use Apache::Request ();                  # Apache stuff
use GD::Graph::pie;
use constant TITLE => "Morning Commute Time: Pie Chart";

my $r = shift;                           # Apache stuff
my $graph = new GD::Graph::pie( 300, 300 );
my @data  = (
    [ qw( Monday  Tuesday  Wednesday  Thursday  Friday ) ],
    [      33,  24,  23,  19,  21   ],
);
$graph->set( 
    title           => TITLE,
    '3d'            => 2
);
my $gd_image = $graph->plot( \@data );
$r->content_type('image/jpg');          # Apache stuff
$r->send_http_header;                   # Apache stuff
binmode STDOUT;
print $gd_image->jpeg;
exit;

You could just include the script in a HTML like:

<html><body>
<p>My Pie Chart</p>
<img src=trygd.pl>
</body></html>

At least, you (or I) want to know you can stream binary directly to a browser from your Web server (as opposed to writing a graph to a temporary file).
