# LaTeX Error: Unknown graphics extension: .ps

When I try to compile this file http://danjer.doudouke.org/_media/tech/dokutexit/playground.zip this error occurs:

``````! LaTeX Error: Unknown graphics extension: .ps.
``````

I'm using TeXworks Version 0.4.3 (MiKTeX 2.9) and pdfLaTeX.

1. You could compile with pdfLaTeX, if you add the line

``````\usepackage{auto-pst-pdf}
``````

for automatic conversion of the PS images to PDF. It requires the option --enable-write18 set. Check the TeXworks preferences, Typesetting, Processing tools, pdfLaTeX:

2. You can compile it with XeLaTeX, which is directly supported by TeXworks. You can choose XeLaTeX in the drop-down menu.

For compiling with XeLaTeX, remove these two lines from the preamble, as XeLaTeX natively supports UTF-8:

``````\usepackage{ucs}
\usepackage[utf8x]{inputenc}
``````
3. Use LaTeX in DVI-mode, and convert as needed, using dvips and ps2pdf, or dvipdfm(x). You can call `latex` at the command prompt, or define a new tool for TeXworks in the preferences:

Seems to work! But there are now different errors. I will figure this out... –  powtac Jan 20 '12 at 17:17
@powtac I was able to successfully compile that project both with pdfLaTeX and XeLaTeX, as described. If you encounter different problems or have follow-up questions, perhaps post a new question, with a link to this question. –  Stefan Kottwitz Jan 20 '12 at 17:26
