//前一视图
private void Redo(IActiveView activeView)
{ activeView.ExtentStack.Redo(); activeView.Refresh(); }//后一视图private void Undo(IActiveView activeView) { activeView.ExtentStack.Undo(); activeView.Refresh(); }
调用AE的ControlsMapZoomToLastExtentBackCommand就OK了 在你的那个工具的click事件下写入如下代码
//上一视图 ControlsMapZoomToLastExtentBackCommand LastExtent = new ControlsMapZoomToLastExtentBackCommand(); LastExtent.OnCreate(MapConMain.Object); LastExtent.OnClick();
地图平移，可以说是最重要的功能之一，许多地图的默认工具就是平移。AE实现平移，比较简单，代码如下
1: ///
2: /// 地图漫游工具
3: ///
