Public Overridable Sub OnPageRenderOnDemand ( e As PageRenderOnDemandEventArgs )
Inheriting classes can override this method to perform other tasks or cancel the object data addition altogether. If this method is overridden in an inheriting class, you must call the base implementation.
This method is called whenever a request is made for an image for a document which is rendered on demand (whether the page is already rendered or not).
