use warnings;
use strict;

use GD;
use GD::Text::Align;

@ARGV or die "Need an image file\n";

for my $img_file (@ARGV)
{
    my $gd = GD::Image->new($img_file) or die;
    my ($w, $h) = $gd->getBounds();
                        
    my $gdt = GD::Text::Align->new($gd,
       valign => 'bottom',
       halign => 'right',
       text   => 'Some Text',
       colour => $gd->colorResolve(0,0,0),
    ) or die;
    $gdt->set_font('arial', $h/10) or die;
    $gdt->draw($w, $h, 0) or die;

    open(GD, ">$0.png") or die;
    binmode GD;
    print GD $gd->png;
    close GD;
