Hi, again, you were right. 
I think of a "drawable" as a Gtk2::Drawable object. A Gtk2::Gdk::Pixmap
is a Gtk2::Drawable, so not realizing that was the problem.

With a fresh mind this morning, I finally
realized that I was reading from the viewport, but that $pixmap itself
is a Drawable object. I was getting confused by trying to make sure the
HRuler was visible in the saved file. A bit of redesign should fix that.

$lpixbuf->get_from_drawable ($pixmap,  # not $viewport->window
           undef, 0, 0, 0, 0, $width, $height);                

# now printing $lpixbuf to file saves the whole 2400 pixels. 

So this solves it, thanks again.
