Hi Gigi,
I don't know how to enlarge the buffer, but this error can arise because there are too many things floating about in addition to the figure itself.  In the past when this has happened to me, I've put a \clearpage just before the figure in question and the problem went away.

Subject: [MiKTeX] Buffer size exceeded.

Hello everybody!
I have a problem to compile a miktex file because probably a figure is too large.
This is the message I've found in the log file:
! TeX capacity exceeded, sorry [buffer size=200000].
<read 0>

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.
It is possible to enlarge the default buffer size in TeX? Anybody knows how can I make it?
Thank you very much for the help!
