一个简单填充的示例（有透明效果）：

var symbol = new SimpleFillSymbol(
            SimpleFillSymbol.STYLE_SOLID,
            new SimpleLineSymbol(
              SimpleLineSymbol.STYLE_SOLID,
              new Color([255,0,0,0.65]), 2
            ),
            new Color([255,0,0,0.35])
          );

图片填充：

// fill symbol used for extent, polygon and freehand polygon, use a picture fill symbol
// the images folder contains additional fill images, other options: sand.png, swamp.png or stiple.png
var fillSymbol = new PictureFillSymbol(
  "images/mangrove.png",
  new SimpleLineSymbol(
    SimpleLineSymbol.STYLE_SOLID,
    new Color(‘#000‘),
    1
  ),
  42,
  42
);

点状样式：

// markerSymbol is used for point and multipoint, see http://raphaeljs.com/icons/#talkq for more examples
var markerSymbol = new SimpleMarkerSymbol();
markerSymbol.setPath("M16,4.938c-7.732,0-14,4.701-14,10.5c0,1.981,0.741,3.833,2.016,5.414L2,25.272l5.613-1.44c2.339,1.316,5.237,2.106,8.387,2.106c7.732,0,14-4.701,14-10.5S23.732,4.938,16,4.938zM16.868,21.375h-1.969v-1.889h1.969V21.375zM16.772,18.094h-1.777l-0.176-8.083h2.113L16.772,18.094z");
markerSymbol.setColor(new Color("#00FFFF"));
