Try something like in this example code. After getting your bbox('all'), do your configure, then adjust the scrollbars.

# add these lines to force scroll to the ends my @bbox = $can->bbox( 'img' ); $can->configure(-scrollregion => [@bbox] ); $can->xviewMoveto(1); $can->yviewMoveto(1);
See example code in Tk photo pixel colors
