I was thinking about that. Theoretically, yes, to a certain degree, but PDFs are rarely produced through the intermediate format. The problem: the feature will only work (have any effect) if the IF is serialized and rendered/painted later. When rendering is done in one pass, the painter kicks in before all the resources are known. > <snip/> > > Vincent Jeremias Maerki
