I has been over 10 years since I needed to display graphics using TeX. Previously I would use:

\usepackage[pdftex]{graphicx}

and later something like

\includegraphics{Fig_02.png} \hfil

Now, TeXworks tells me that I have an undefined control sequence in my \usepackage statement. My searches on the web to find out how this is done currently keeps referring me to LaTeX.

Any pointers would be appreciated.

  • Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem.

  • Additionally, the [pdftex] option is rarely (if ever) needed any more. The graphicx package and others can almost always detect whether they're being run under pdftex or other engines.

  • But there is no problem in the \usepackage statement itself, even though it is better not to specify the pdftex option if you don't need to.

  • Mike, thank you for your answers. I am using Tex, not LaTex. I believe your document comments apply to LaTex. That being the case, my question remains. How should I display a png file using pdftex? Or using Tex?

  • \usepackage{graphicx} \includegraphics{Figure10.png} \bye

Before answering, let me ask again: Do you really want to use plain TeX?

If so, here's a document that should compile with pdftex:

\input miniltx
\input graphicx

\includegraphics{Figure10.png} 

\bye

  • Problem solved! The answer to your question is a bit more complicated. But since you favored me with an answer I should do the same. I started using plain Tex in the late 1980's and over some years developed a set of macro's that allow me to do just about anything I wish. Now I use Tex very infrequently and question whether it is worth it to me to come up the LaTex learning curve. Thank you so much for your assistance.
