Can edit map in Rviz?

edit

Thx for reply. Should this function(map editor) can be implemented by building a new plugins of rviz?I now try to make it in rviz.Can you give me some advice?

You might be able to do it, but you will probably have a hard time.

The interactive elements of Rviz are not good for image editing, so you will probably have to work hard to make a good user interface.

The ROS nodes which can publish the map (gmapping, map_server and others) are not designed to receive updates, so you will need to come up with a different way to publish and save the updated map.

ok, thx, I just want to edit the saved map to add something like glass walls、some tables that lasers can't detect and other things like these.So the function for me, it's just a image editor in Rviz.I'll try, thx for your time and advice.
