>Does having tagged content not require the ParentTreeNextKey value to be >updated?! You're laboring under a misconception of how marked content and MCIDs in particular work. It should be called an MCIdx. That would cause much less confusion. MCIDs aren't unique. They're indexes into an array of their marked content container. Pages are containers, XObject forms can be containers, as can various annotations (if one is up to the task... ouch). The top level of this documents structure tree only has one container, the first (and only) page. Within that page, you'll find an array of marked content objects. The indexes within that page's content stream don't affect the ParentTreeNextKey. ***Note that the order in which objects appear in the parent tree has no bearing on their logical order.*** Yep. Logical/reading order is determined solely by the order in which children appear in the /K (kids) arrays. You're not the first person to make this mistake by a long shot. Older versions of Adobe's own LifeCycle Designer (8.0 IIRC) would pad the parentTree arrays of every page after the first with enough nulls to make the MCIndexes unique across all pages. I'd imaging there are some PDFs floating around out their in the wild with HUNDREDS of nulls just sucking up space due to this very misunderstanding. I had a boatload of fun working this out on my own a year or two ago. Not quite as much fun as implementing PDF's crypto system with the old and easily-misunderstood documentation, but still... --Mark Storer Senior Software Engineer Cardiff.com ------------------------------------------------------------------------------ _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php Check the site with examples before you ask questions: http://www.1t3xt.info/examples/ You can also search the keywords list: http://1t3xt.info/tutorials/keywords/
