According to the docs, setIcon either takes a string or a MarkerImage object. Initially you set a MarkerImage, but in your listener code, you do not construct a MarkerImage. Try something like this instead:

    for(i=0; i< markers.length; i++ ) {
    var icon = markers[i].getIcon();
    markers[i].setIcon(new google.maps.MarkerImage(
        icon.url,
        new google.maps.Size(largeur, hauteur),
        new google.maps.Point(0, 0),
        new google.maps.Point(0, 0),
        new google.maps.Size(largeur, hauteur))
    );
}
