As an addition to my mail. I tried poppler pdfseparate and pdfunite, but the resolution is too high and my extract is much eavier than the original file. As an alternative, Is there a way to compile just a part of a context file, keeping the whole toc? My college pupils will get lost if my 3) is changed to a 1) (don't whether this is only typicall for French pupils). Regards, Damien Thiriet
