This set of functions is available when the AppProjection plugin is loaded. This plugin allows creating multi-projector setups.
Notice
AppProjection plugin cannot be used in a Qt-based application
If the plugin is loaded together with the engine, the HAS_APP_PROJECTION definition is set. This definition can be used, for example, to avoid errors if the plugin is not loaded: the code in which the plugin functions are executed can be wrapped around as follows:
