Hi everyone!
 
This is my first posting on here. I just wasn't able to find the right terms to feed a search engine with. Sorry if my answer is too stupid or something.
 
Suppose there's a CGI script that shall output a PNG graphic, like this:
 
#!/usr/bin/perl
use strict;
use GD;
my $infile = "/opt/apache/icons/apache_pb.png";
my $data;
open (my $in_fh, $infile) or die;
while (<$in_fh>){
        $data .= $_;
}
close $in_fh;
my $image = GD::Image->newFromPngData($data, 1);
print "content-type: image/png\n\n";
print $image->png;

In reality, I'm going to draw a few annotations onto the PNG, using the GD library.
 
What I'd like to accomplish is that the script should bring its own data, without having to do a read operation, the path to the file needing to be configured, and needing to catch open errors in a more graceful way than I did in my example.
 
How would I encapsulate my data in the script?
 
Thanks in advance everyone!
