Aha! I think you want to set the -scrollregion. Set the -scrollregion after you have populated the canvas so that the scrollbars can reset to where they need to be. I loaded a 300x300 image and the scrollbars were not there, then I loaded a 400x400 image and the scrollbars both appeared.

use Tk 800.000; use Tk::Canvas; use strict; my $main = Tk::MainWindow->new(); my $canvas=$main->Scrolled('Canvas', -scrollbars => 'osoe', -bg=>'white', -width=>300, -height=>300, )->pack(); my $image300x300 = $canvas->Photo(-file=>'300x300.gif'); my $image400x400 = $canvas->Photo(-file=>'400x400.gif'); my $id = $canvas->createImage(200,200,-image => $image400x400); # configure the scrollregion AFTER you populate the # canvas widget to reset the scrollbars $canvas->configure( -scrollregion => [ $canvas->bbox("all") ]); MainLoop;

Is this what you're looking for?
