Feeding video data to Imager

[saintmike]

When feeding RGB (or, more accurately, BGR) data from a video source to Imager, a wise perlmonk once suggested to use this trick:

    use Imager;
    my $i = Imager->new();
    $nfr = reverse $nfr;
    $i->read(
      type => "pnm", 
      data => "P6\n$width $height\n255\n" . $nfr
    );
    $i->flip(dir => "hv");

Is this still the best way to do it? It seems awkward that the mighty Imager wouldn't allow feeding it RGB data directly.
