I already tried this (I should have told you).
The TeXgraph program can export eps or pdf files. Right now, the plugin can
output eps file directly or eps converted from pdf (with pdftops).
The problem is that the screen quality of "pdf-to-eps files" is not really
good
and eps looses real transparency. So I wanted to know if it was possible to
include jpg or pdf files (without convertion to eps) into a TeXmacs file.
You can have a look at the tm_texgraph file below.

Thank you.
