Firstly, I don't do a lot of work with images, so this mightn't be the 
best way to do it:)
Gtk2::Gdk::Pixbuf has image scaling support, eg:

$pixbuf = $pixbuf->scale_simple(
  $width,
  $height,
  'nearest'
);

I don't know if you can make a Gtk2::Gdk::Pixbuf directly from an xpm - 
never tried, probably works, but I'm sure there's a way. Once you've got 
your scaled image, you can go:

$img = Gtk2::Image->new_from_pixbuf ( $pixbuf );
