Error in PS generated by MetaUML

Question

If I use following example (or any other):

input metauml;

beginfig(1);
Class.A("Point")
       ("+x: int",
        "+y: int") ();

Class.B("Circle")
       ("radius: int")
       ("+getRadius(): int",
        "+setRadius(r: int):void");

topToBottom(45)(A, B);

drawObjects(A, B);

clink(aggregationUni)(A, B)
endfig;

end;

It generates PS that I cannot view in evince and gs:

What am I doing wrong?

Edit: When I use pdflatex it generates a proper pdf (at least with /usr/share/ghostscript/GS_Version/Resource/Init/Fontmap.GS modified)

Do you get the same style of errors if you generate pdf? (and not ps) — Johan, Nov 15 '10 at 05:26

I too had the same problem. Fortunately, I just now came across the solution: Displaying MetaPost output in ghostscript

To avoid this problem, as they suggested, you just have to add the following line at the beginning of your .mp file:

prologues := 2;

Then process your .mp file with gs or convert or whatever tool you like.

I'm not much knowledgeable about MetaPost, so, I don't know what exactly it does. But it atleast avoid that irritating error :)

Hope others find it useful too!

Linking the the UK FAQ is a good idea, but it's also useful to add a summary of the material here so that {TeX} stands "on it's own". Please consider editing your answer to include what you did: you'll get more upvotes that way. – Joseph Wright Feb 27 '11 at 11:49

In general, prologues:=3; is safer, as that actually includes a font subset in the generated PS, so that it will also work for fonts that do not exist in the ghostscript installation at all. – Taco Hoekwater Feb 28 '11 at 10:35

create a LaTeX document:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics{<mpfile>.1}
\end{document}

or use mptopdf from ConTeXt or use it this way

mpost -tex=tex <mpfile>
tex "\input epsf\relax\epsfbox{<mpfile>.1}\bye"
dvips zz

it will generate a ps with included ptmr8r font. replace with your file name.

If you do not want to edit your files you can create a custom memory dump:

mpost -ini <<EOF

\input plain
prologues := 2
\dump

EOF

You should get a mpout.mem file. Rename it to whatever you like (say foobar.mem) and use it with:

mpost '&foobar' file

You could define an alias:

alias mp2eps="mpost '&foobar'"

(You might want to place the mem file into the kpathsea search path but I do not know how to set it up).

There is probably something wrong with the font ptmr8r. A quick googling found some advice at http://www.mediawiki.org/wiki/Extension:UML on how to fix that.
