Looking at the PDF spec, I think that should be possible. In PDF Reference 1.4, see 8.4 Annotations and 8.5.2 Trigger Events. You can probably control the hidden attribute of an annotation using a mouse-over trigger event using a "hide action". > any ideas whether this would be hard to implement? The part in PDF is probably not all that hard. A few minor improvements to the PDF library should get you there. The harder part is to write a Batik extension that works with the PDF transcoder to generate the right elements in PDF. Since I've never written an extension in Batik, I don't know how much work that would be. Better ask on the Batik users list for ideas on that. Good luck!
