You can use the same styles as for a normal styled map to make a static map using GMaps.js:
url = GMaps.staticMapURL({
size: [610, 350],
lat: -12.043333,
lng: -77.028333
styles: [{
featureType: "all",
elementType: "all",
stylers: [
{ hue: '#FF0000' }
]
},
{
featureType: "landscape",
elementType: "all",
stylers: [
{ hue: '#0A2D3F'},
{ saturation: 50 },
{ lightness: -10 }
]
}]
});
$('<img/>').attr('src', url)
.appendTo('#map');
