Hello,

I have this code using Geo::GoogleEarth::Pluggable to create KML documents. I would like to add a "ScreenOverlay" to a KML generated with such module that would store a BMP legend for my point but I don't know how I can add it. This is the code generating the two KMLs:

use strict;
use Geo::GoogleEarth::Pluggable;

my $document=Geo::GoogleEarth::Pluggable->new(
    name=>'dummy',
    description=>'bbb',
);

$document->LookAt(
    latitude  => 50,
    longitude => 0,
    range     => 30000,
    heading   => 0,
    tilt      => 0,
);

my $folder;
$folder = $document->Folder(name=>"FOLDER_1", description=>"FOLDER_1")
+;
my $icon_style = $folder->IconStyle(
    color   => {red=>255, green=>0, blue=>0},
    href    => "http://maps.google.com/mapfiles/kml/shapes/square.png"
+,
    scale => 0.4
);

my %point = (
    name=>'POINT_1',
    lat=>50,
    lon=>0,
    alt=> 0,
    description=>'POINT_1',
    style => $icon_style,
);
$folder->Point(%point);
my $kstring = $document->archive;
my $kfile = 'dummy.kml';
open(KK,">$kfile") or die "$kfile $!";
print KK $kstring;
close (KK);

my $kml_legend_file = 'dummy_legend.kml';
open (KML,">$kml_legend_file") or die $!;
print KML qq(<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.googl
+e.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:a

<ScreenOverlay id="idLegend">
    <name>dummy_legend</name>
    <description></description>
    <Icon>
        <href>dummy_legend.bmp</href>
    </Icon>
    <overlayXY x="0" y="1" xunits="fraction" yunits="fraction"/>
    <screenXY x="0" y="1" xunits="fraction" yunits="fraction"/>
    <rotationXY x="0.5" y="0.5" xunits="fraction" yunits="fraction"/>
    <size x="0" y="0" xunits="pixels" yunits="pixels"/>
</ScreenOverlay>
</kml>);
close (KML);

Thanks for any suggestion on how to come up with a single KML with the ScreenOverlay included.
