ae开发基础功能
放大、缩小、pan、框选要素(新建命令,建立命令HOOK,赋给当前地图控件):
ICommand cmd = new ControlsSelectFeaturesTool();
cmd.OnCreate(axMapControl1.Object);
axMapControl1.CurrentTool = cmd as ITool;
取消要素选择(层——要素选择——清空):
IFeatureSelection pfs = axMapControl1.get_Layer(0) as IFeatureSelection;
pfs.Clear();
axMapControl1.Refresh();
axMapControl1.CurrentTool = null;
