[Message part 1 (text/plain, inline)]

Dear Tassilo,

as far as I understood, the principle is that \psfragfig calls an external
process to perform an "encapsulated" LaTeX->PS->PDF run, applied on a
synthetical LaTeX document that contains the *.eps file. It replaces all
expressions found in the *.eps file (say, a letter "a"), by the
corresponding expression given by psfrag (say, a proper math symbol a):

\psfrag{a}[cc][cc][1.3]{$a$}

Now whether the figure environment contains this line, or the user provides
a separate file, exactly named as the corresponding *.eps file, that
contains all replacements for that *.eps figure.

So, to make psfragfig working, I always thought that -shell-escape is
absolutely needed!

I am not sure whether this was your question, but if I can help, please let
me know.

Best wishes,
Tobias

Ah, indeed, both exist.  But I specified example-image.eps at the first try
and then it complained that example-image.eps.eps did not exist.

So it seems that depending on if -shell-escape is used, \psfragfig either
expects/prefers an eps or a tex file?

Bye,
Tassilo
