Patrick,
Thank you very much for this. It works very nicely creating a small file and
yet enabling a nice consistency in the document. It took me ages to find the
options for \clip your hint seemed to suggest that it was in details.pdf. It
turned out to be in the Metafun manual. I finally used
\clip[width=xxx,height=yyy,hoffset=xx,voffset=yy]{\externalfigure[pic]}
\scale I could find no documentation for but I discovered that the
\scale[width=xxxx] provides the appropriate magic when needed. It is a pity
that setup-en.pdf is not up to date with these commands the various texshow
and other web tools that people have developed are missing them as well. I
imagine a single source of all the commands would help these developers
enormously.
Thanks again
