Dear friends,
I am trying to use the following module in a project of mine...
https://metacpan.org/pod/Bio::Graphics::DrawTransmembrane

[download]

It works fine, but I was wondering, is there a way that I can tilt the bars to have an angle, instead of being vertical?
My code, based on the module, which uses GD-graph, is the following:
use DrawTransmembrane;
$topology_final = 'IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
+IIIIIIIII0IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
+IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIMMMMMMMMMOOOOO
+OOOOOOOOOOMMMMMMMIIIMMMMMMMMMOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMM
+MMMMMMIIIMMMMMMMMMOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMIIIIIIIMMMM
+MMMMMMMOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMIIIMMMMMMMMMMMOOOO
+OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMIIIIIMMMMMMMMMOOOOOOOM
+MMMMMMMMMMIIIMMMMMMMMMMMOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMM
+MMMMMIIIIMMMMMMMOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMIIIMMM
+MMMMMMMMOOOOOOOOOOOOOOMMMMMMMMMMMIIIIIMMMMMMMMMOOOOOOOOOOOOOOOOOOOOOO
+OOOOOMMMMMMMMMMMIIIMMMMMMMOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMM
+MMMMMM';

@total_top = ();
if($topology_final=~/M/)    
{
    while ($topology_final =~/(.)\1*/g)
    {
        if ($1 eq "M")
        {
            my $start_TM = $-[0] + 1;
            my $end_TM = $+[0];
    
            push @total_top, $start_TM;
            push @total_top, $end_TM;
        }
    }
            

    my $image = DrawTransmembrane->new
    (
        -title=>"topology prediction image",
        -n_terminal=>'in',
        -topology=>\@total_top,
        -bold_helices=> 1,
        -bold_labels=>1,
        -text_offset=>-25,
        -helix_label=>'b',
        -outside_label=>'Extracellular',
        -inside_label=>'Periplasm',
        -membrane_label=>'Membrane',
        -helix_width=>30,
        -vertical_padding=>150,
        -horizontal_padding=>120,
        -n_terminal_offset=>50,
        -n_terminal_height=>220,
        -c_terminal_offset=>30,
        -c_terminal_height=>220,
        -helix_label=>'Sheet',
        -colour_scheme=>'yellow'
    );    

    open (OUTPUT, '>', 'test.png');
    binmode OUTPUT;
    print OUTPUT $image->png; 
    close (OUTPUT);
}

Any tips would be greatly appreciated... The goal should be to tilt the bars a bit, like, e.g. in:
