First the others are right there is no real reason to complcate this with references a simple copy by value is fine here, and there is no need to redo what has been done...

Now looking at the question I have to say that I grabbed your code and stripped to the most simple form and tested it. It doesn't have the derefeencing problem you mention 
($width, $height) = gifdim('test_text');
print "Height = $$height  Width = $$width \n";
exit;
sub gifdim ($) {
    my $filename = $_[0];
    my $height =200;
    my $width =300;
    return \($width, $height);

}

[download]
output:Height = 200 Width = 300

So im not sure what problem you are having.
