I’d like to use Aspose.XPS to modify existing XPS page content. I can see how I might insert a blank FixedPage into an XPS file, and if activate is true, subsequent Insert operations will add content to that new FixedPage.
But I don’t see how I can start with a pre-existing XPS file, and for instance select a particular FixedPage and then add an image on that page at a particular point in the z-order. Is it the SelectActivePage method?
The github samples for Aspose.XPS don’t demonstrate the required behaviour. And the on-line help doesn’t seem to have any sample code snippets at all.
Can you tell me how to select an existing XPS page and then modify it?
