Don't do it the hard way! If you do end up needing to do this, use

Until they change the software without telling you.

There's also GD, which is a bit older, but I find that Imager covers
all the image manipulation I want to do. Creating a reduced-size image
with the same aspect ratio, which I think was what you were talking
about, is as simple as:
my $img=Imager->new(file => $in);
my $tn=$img->scale(xpixels => 512,
ypixels => 512,
type => 'min');
$tn->write(file => $out);
which will result in one no bigger than 512 pixels in either
dimension. Other options are available.
