Can Anybody tell me how to embed scalebars and legends in mapscript?

I've tried this code without results...

function DrawMaptoPrint() {
    GLOBAL $gpoMap;
    GLOBAL $gAppletImgFmt;

    $gpoMap->scalebar->set(status , MS_EMBED);
    $gpoMap->scalebar->set(position , MS_UL);

    $img =3D $gpoMap->drawScaleBar();
    $gpoMap->embedScalebar($img);
   =20
    $img =3D $gpoMap->draw();
    $gpoMap->drawLabelCache($img);

    $url =3D $img->saveWebImage($gAppletImgFmt, 0, 0, -1);
    printf("<img src=3D%s width=3D%d height=3D%d>\n", $url, =
$gpoMap->width, $gpoMap->height);...
}

map file:

SCALEBAR
  IMAGECOLOR 255 255 255
...

 POSTLABELCACHE true

...

END

I could'n find nothing about this issue on the mailing list..

Thanks

Eduin
