Ah, I had missed this one. > Which is about all that I can find in the standard about this. In the final draft (I don't have the official standard, damned be ISO for their closed policy), a couple of lines below you have: "left-header: is an unlabeled sosofo containing only inline flow objects that is aligned with the left margin of the page in the header line." This is the one I based myself on. I don't know whether we should infer that the standard contradict itself, or whether the first statement restrict the second one. At least I don't know what's the point of duplicating 6 times an unrestricted statement, just to have all of them further restricted by another one, distant in the text :( > So, my opinion on images in headers/footers is that [...] > - If it did work it would break the standard I guess that (open)jade accepting displayed sosofos here is a bug. Maybe accepting someting other tha text is also a bug. But DSSSL is extensible. I don't know whether the extension would be allowed to use the existing "left-header" & such properties, but at the very least, propserties like "displayed-left-header" could be created as an extension. > The last point is enough to make me not want to spend any more hours > struggling with jadetex, fancyhdr etc. Yay, that's the only one against which I had something to say ! ;) > So, if you want that feature then I think the best thing is to look to > XSLT... Or to implementing page-sequence ? I've not looked deep into this, and have no idea of the difficulty to map this to TeX... -- Yann Dirson <Yann.Dirson@fr.alcove.com> http://www.alcove.com/ Free-Software Engineer Ingénieur Logiciel-Libre Free-Software time manager Responsable du temps Informatique-Libre Debian GNU/Linux developper <dirson@debian.org>
