I am using Plain TeX for a document that has illustrations and uses colored type. I find that when I load both miniltx and color I get an error message on the console. Looking at the files where the error occurs I see that I am way out of my depth. Can someone suggest how to overcome this problem? Here is my source code and the console message

Source Code

\input color


\input miniltx

\input graphicx.sty


\centerline{ \includegraphics[width=2.5in]{Klein125}}
\kern -20pt
\centerline{Figure 125}

    If I replace Klein125 with a file present on my machine (example-image-duck from duckuments or example-image from mwe) the file compiles fine for me (up-to-date MikTeX 2.9). – moewe Feb 13 at 14:34
  • I can reproduce the issue if I move the \resetatcatcode to before \input graphicx.sty in the MWE. Can you double-check its position? – moewe Feb 13 at 14:40

    in any case color.tex and graphics.tex both input miniltx so there is no need to input miniltx explicitly. Also of course just using latex is simpler and more robust than using plain but inputting half the latex format at run time. – David Carlisle Feb 13 at 14:43
  • This clarifies what is going on. I have been loading miniltx twice and that is probably what is screwing things up. I will experiment and see what happens. Thank you. – Peter Renz Feb 13 at 22:39
  • \input color \input graphics.sty \resetcatcode figure 125 \bye Gives the same problem. Switching to LaTeX would require my tossing out my macros and choices of fonts. Switching to MikTeX would require my learning a new environment, even more disruptive. The odd thing is that I am using color and graphics in a similar document on my system with no problems. – Peter Renz Feb 13 at 23:13
