Hi Monks.

I am quite interested in using perl (ideally) to extract GPS coordinates embedded in an image taken with a modern cell phone camera. I have started writing such a (fledgling) application (see below) but I was wondering if there was a convenient way to transform the binary data into a more "user friendly", i.e., readable, format? Perhaps using pack? 

use warnings;
use strict;

my $file;
my $data;

print "Please enter the file name: ";
chomp($file = <STDIN>);

open IMG, $file or die "Error : $!\n";
binmode IMG;

$data = do{local $/; <IMG>};
close IMG, $file or die "Error : $!\n";

Thanks.
