    In This Topic
    Sets the visibility of all layers except those listed in the layers array, in the context of an end-user UI. The layers array can contain layer names (strings) or OptionalContentGroup references. The state is interpreted as follows:
    • true: the user explicitly made all layers (except the specified ones) visible.
    • false: the user explicitly made all layers (except the specified ones) hidden.
    • a null reference (Nothing in Visual Basic): the user did not change the visibility of the layers.
