[Bioperl-l] Clickable Glyphs...

Get the latest CVS version of bioperl-live and read the section of the 
Bio::Graphics::Panel manual page labeled "Creating Imagemaps."  
Essentially what you need to do is to replace the section after you 
create the panel with this:

	my ($url,$map,$mapname) - $panel->image_and_map(
						-root => '/var/www/html',
						-url   => '/tmpimages');
	print $q->header(),$q->start_html('A Bitmap Rendering');
	print $q->img({-src=>$url,-usemap=>"#$mapname");
	print $map;
	print $q->end_html;

I'm frankly more fond of the function-oriented CGI calls, so I would 
bring in the standard functions and then:

	print header(),
		start_html('A Bitmap Rendering'),
		img({-src=>$url,-usemap=>"#$mapname"),
		$map,
		end_html();
