该范例程序会演示如何绘制多种样式的地标，包括：谷歌样式地标、闪动告警地标、可旋转的地标、矢量圆形地标、固定大小的圆形地标，十字地标。
注意1：太乐地图.NET控件 名称统一命名为：MapControl
注意2：该范例程序涉及到1个地图事件：DrawMarker
范例运行后界面如下图所示：
手绘谷歌样式地标

手绘闪动告警地标
/// <summary> /// 手绘地标（可自定义图标样式，并且进行闪动告警） /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void button2_Click(object sender, EventArgs e) { MapControl.ToolBar = MapToolBar.Point; MapControl.DrawMarker(DrawFlashMarkerCallBack); MessageBox.Show("请在地图上点击..."); }
