Controlling the visibility of CS and RT layers

You control the visibility of the CS layers via the View object. Use the Document object in order to determine which layers are to be displayed or hidden in runtime. You can control the visibility of the CS and RT layers with the following methods:

"IsCSLayerVisible(Index)" method: checks whether the specified CS layer is displayed.

"SetCSLayerVisible(Index, Val)" method: displays or hides the specified CS layer.

Use the IsRTLayerVisible and SetRTLayerVisible methods for the RT layers in the same way.
