If you’re +debugging your MetaPost code, you may want to view it in +<i>ghostscript</i> (or some other PostScript previewer). However, +the PostScript ‘engine’ in <i>ghostscript</i> <em>doesn’t</em> +ordinarily have the fonts loaded, and you’ll experience an error such +as +<blockquote> +<pre> +Error: /undefined in cmmi10 +</pre> +</blockquote><p> +There is provision in MetaPost for avoiding this problem: issue the +command <code>prologues := 2;</code> at the start of the <code>.mp</code> file. +<p/>Unfortunately, the PostScript that MetaPost inserts in its output, +following this command, is incompatible with ordinary use of the +PostScript in inclusions into (La)TeX documents, so it’s best to +make the <code>prologues</code> command optional. Furthermore, MetaPost takes a +very simple-minded approach to font encoding: since TeX font +encodings regularly confuse sophisticated minds, this can prove +troublesome. If you’re suffering such problems (the symptom is that +characters disappear, or are wrongly presented) the only solution is +to view the ‘original’ MetaPost output after processing through +LaTeX and <i>dvips</i>. +<p/>Conditional compilation may be done either +by inputting <i>MyFigure.mp</i> indirectly from a simple wrapper +<i>MyFigureDisplay.mp</i>: +<blockquote> +<pre> +prologues := 2; +input MyFigure +</pre> +</blockquote><p> +or by issuing a shell command such as +<blockquote> +<pre> +mp '\prologues:=2; input MyFigure' +</pre> +</blockquote><p> +(which will work without the quote marks if you’re not using a Unix +shell). +<p/>A suitable LaTeX route would involve processing +<i>MyFigure.tex</i>, which contains: +<blockquote> +<pre> +\documentclass{article} +\usepackage{graphicx} +\begin{document} +\thispagestyle{empty} +\includegraphics{MyFigure.1} +\end{document} +</pre> +</blockquote><p> +Processing the resulting DVI file with the <i>dvips</i> +command +<blockquote> +<pre> +dvips -E -o MyFigure.eps MyFigure +</pre> +</blockquote><p> +would then give a satisfactory Encapsulated PostScript file. This +procedure may be automated using the <i>Perl</i> script +<i>mps2eps</i>, thus saving a certain amount of tedium. +<p/>The Plain TeX user may use an adaptation of a jiffy of Knuth’s, by +Dan Luecking. Dan’s version <i>mpsproof.tex</i> will work under +TeX to produce a DVI file for use with <i>dvips</i>, or +under PDFTeX to produce a PDF file, direct. The output is +set up to look like a proof sheet. +<p/>A script application, <i>mptopdf</i>, is available in recent +(La)TeX distributions: it seems fairly reliably to produce +PDF from MetaPost, so may reasonably be considered an answer to +the question... +<dl> +<dt><tt><i>mps2eps</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/support/mps2eps.zip">support/mps2eps</a> (<a href="ftp://cam.ctan.org/tex-archive/support/mps2eps.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/support/mps2eps/">browse</a>) +<dt><tt><i>mpsproof.tex</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/graphics/metapost/contrib/misc/mpsproof.tex">graphics/metapost/contrib/misc/mpsproof.tex</a> +<dt><tt><i>mptopdf</i></tt><dd>Part of <a href="ftp://cam.ctan.org/tex-archive/macros/pdftex/graphics.zip">macros/pdftex/graphics</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/pdftex/graphics.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/pdftex/graphics/">browse</a>) +</dl> +<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=mpprologues">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=mpprologues</a> +</body> |
