Map Icon Marker Size

[HIGH]/*
* Add the Town Markers
*/
for (int i = 0;i < the_points.size();i++) {
GpsPoint the_pt = the_points.get(i);
Float lat_v = the_pt.lat;
Float lng_v = the_pt.lng;
String marker_name = the_pt.name;
String marker_desc = the_pt.desc;
String marker_icon = the_pt.icon;
mMap.addMarker(new MarkerOptions().position(new LatLng(lat_v, lng_v))
.title(marker_name)
.snippet(marker_desc)
.icon(BitmapDescriptorFactory.fromAsset("scroll_images/"+marker_icon)));
}[/HIGH]So I have my map loading the icons, which is cool.
But they are coming through quite small.
ANy way I can set the rendered size?
