Q: There are multiple layers in the map. How to save the clipping results? And these are no follow-up operations after you check the "clipping region".

A: The clipping region check box in the map properties tab controls the map display range。 When you set a mask, the map only shows the data in this range, no clipping operation. To perform the clipping operation, please select the map clipping button in the map operation tab, and you can set the clipping result in the pop-up dialog box.
