Hello,

Is it possible to include PostScript graphics, or literal PostScript in ge=
neral, in MP files?
The purpose is to composite multiple images with correct alignment.
It's possible to do this in TeX (see below), but it would be nice to be ab=
le to do this directly in MP.

I've determined that this doesn't work:

%prologues :=3D 3;
%outputtemplate :=3D "%j_%c.ps";

outputformat:=3D"png";
outputformatoptions:=3D"format=3Drgb antialias=3Dnone";
outputtemplate :=3D "%j_%c.png";

verbatimtex \input epsf etex;

path q[];

beginfig(1);
  q0 =3D (unitsquare scaled 2cm) shifted (-1cm, -1cm);
  draw q0 withpen pencircle scaled .333mm;
  label(btex \vbox{\hbox{\epsffile{testdot1.eps}}} etex, origin);
endfig;
end;

It fails silently and the resulting PNG file is just a white square (see a=
ttachment).  It doesn't work with EPS output, either.

It does work to do this in TeX:

\input epsf
\parindent=3D0pt
\parskip=3D0pt
\baselineskip=3D0pt
\advance\hoffset by -1in
\advance\voffset by -1in
\nopagenumbers
\def\epsfsize#1#2{#1}

\vbox to 0pt{\vskip2cm\hbox to 0pt{\hskip1cm
\epsffile{testdot1.eps}\hss}\vss}
\vbox to 0pt{\vskip2cm
\hbox to 0pt{\hskip1cm\epsffile{testdot2.eps}\hss}\vss}
\vfil\eject
\bye

The result is in `testinclude.pdf' (attached).

Any help would be much appreciated.
