The PDF_Include extension that you are using has a
bug. I took some
time today to look at this today and updated the code. You should
update your code and try again:

Thanks, Mark. I see you did a lot, and now it works.
At least, it allows to save the page
with a PDF image and shows the pic.
I made the preliminary test at
http://mizugadro.mydns.jp/h/index.php/Testpdf
There is still a strange thing:
if the PDF figure is loaded at the page,
then it intercepts the keys "command,+" and "command,-" ;
now, the zooming-in and zooming-out apply only to the PDF figures.
However, the buttons "View","Bigger" and
"View","Smaller"
at the Macintosh menu bar seem to work as previously.
At the Linux brousers, the analogies, I suspect,
are "control,+" and "control,-";
so, perhaps, you can reproduce the effect.
Such a mode (if one knows about this) could be useful
to see details of the complicated figures,
without to change the scaling of the description in the text.
however, such a behavior looks unexpected; is it intentional?
I suggest that you keep this option;
althopugh I doubt if it should be default.
Is it possible to make the <pdf> program
to get the data about sizes of the PDF figure from the included file?
I read, you suggest 400px as default size of the figure...
Is it possible to ask the <pdf> to scale the figure to fit the frame
indicated, as a default?
I think, this would correspond to the wiki style of loading of figures
in other formats.
