[Bioperl-l] FeatureFile and pad_left

[Ken]

I'd like to use a FeatureFile object but I can't figure out how to pad the 
left and right sides of the panel.
I've tried to put pad_left in the input file and in the script (see below)
Any suggestions?
Thanks

open OUT, ">/home/ken/outtest.png" or die;
# create a new panel and render contents of the file onto it
my $panel = $data->new_panel;
my $tracks_rendered = $data->render($panel);
print OUT  $panel->png;
