A lot of robospin themes I've played about with had a panscan option in them, just copy the code and put the image you want to scan in the layout folder as "flyer.png" that or change the name in the code:
local bgart = PanAndScanArt( "flyer", 0, 0, flw, flh);
bgart.trigger = Transition.EndNavigation;
bgart.preserve_aspect_ratio = false;
bgart.set_fit_or_fill("fill");
bgart.set_anchor(::Anchor.Center);
bgart.set_zoom(4.5, 0.00008);
bgart.set_animate(::AnimateType.Bounce, 0.50, 0.50)
bgart.set_randomize_on_transition(true);
bgart.set_start_scale(1.1);
local alpha_cfg = {
when = Transition.ToNewSelection,
property = "alpha",
start = 0,
end = 200,
time = 3000
}
animation.add( PropertyAnimation( bgart, alpha_cfg ) );
