iClient如何绘制椭圆？ 我要提问

Question

如何SuperMap iClient for javascript中如何使用SuperMap.Control.DrawFeature来绘制椭圆

Answer 1

drawEllipse = new SuperMap.Control.DrawFeature(vectorLayer, SuperMap.Handler.RegularPolygon,{handlerOptions:
                                    {
                                        sides:50,
                                        irregular:true//设置为true则在第一次鼠标按下时标明多边形边界的一个角，并且随着鼠标的移动绘制其对角点，进而拉伸多边形。即为绘制椭圆；如果设置为true，radius则会被忽略。
                                    }});
