Well, I'm not using HTML::HTMLDoc ... just doing it behind the scenes w/ 
that system() call.  Once the file is done, if you wanted to pass this 
into the browser, you could open() the file and read the bits into an 
$output variable and return that in your runmode.  Or you could trigger 
a download like so:

sub my_runmode {
  # ...
  $self->header_props(
      -type	=> 'application/octet-stream',
      -attachment	=> "$filebase.pdf",
    );
  # gather up $output
  return $output;
}

Don't forget to clean up after yourself by unlinking the pdf file.

Hmm, again, I would put the images and everything into that 
HTML::Template, create a dummy HTML file and let htmldoc do the rest.

Expanding that:

sub my_runmode {
  # Generating png files, writing the files in the same temp directory
  # as the soon-to-be html template file
  $template->param( 'graph1' => 'graph1.png' );
  # You see, in your template file, you'd have something like
  # <img src="<!-- tmpl_var name="graph1" -->" ...>
  $html = $template->output();
  open( FILE, ">/temp/dir/output.html" );
  print FILE $html;
  close ( FILE );

  # ...
  $self->header_props(
      -type	=> 'application/octet-stream',
      -attachment	=> "$filebase.pdf",
    );
  # gather up $output
  return $output;
}

HTH,

Jason
