SuperMap Objects 5.2的视图操作功能扩展

The Functional Expand of View's Operation Based on SuperMap Objects 5.2

针对目前SuperMap Objects 5.2中没有直接提供视图改变时所触发事件的局限性,通过程序开发并结合Be-foreMapDraw和AfterMapDraw事件,扩展了SuperMap Objects 5.2中的视图操作功能,并以广州1∶500、1∶2 000基础地形图以及1∶2 000正射影像图动态调用为例,验证了本方法的可行性。

According to the limitation of the views＇ changing events which SuperMap Objects 5.2 does not provide at present, By using application programs and combination with the events of BeforeMapDraw and AfterMapDraw,The functional expand of viewg operation has been clone, Taking the dynamical calls of 1 ： 500,1 ： 2 000 digital map data and digital orthophoto map data of GuangZhou as an example,The method is verified.
