I see you two are up to it and will probably do a better job than me. I tried to use gs as pdftk. It works but it is pretty slow.

 I suppose you can launch just gs once and do a series of commands to avoid this issue but I haven't found yet how. I also suppose Stefan will use the function doc-view-pdf->png-1 for each page when doing the lazy reconversion which will also call gs once for each page ... if I find a workaround I will share it !

Anyway lazy reconversion is ok for me, and I am happy to have been useful at least  for counting as one among others :)

Thanks to both of you !

Yes, it's far from perfect, but it has its advantages.


up to implementing a feature I don't have a need for myself.  But since
you already have it and people request it, just go ahead for Emacs 24.2.

Damn!  So now I have to go and clean up that hack!
