Hi Helge, I was really looking for an automated approach. For example on Windows, there is 'PDF Factory' (although I haven't tried it with hyperlinks). So I was hoping for something similar on Linux. One reason why an automated approach would be good is that the file can be big and appear big on the page: it /needs/ to be big. But if it's big and appears /small/ on the page, then it needs to be downsampled. Another reason: a LyX document can embed PDFs, SVGs, and I imagine other 'image' files, that can in turn embed bitmaps. One needs a tool that examines the resulting PDF output, rather than the input files. Cheers JP
