Incompatibility with {eepic} #6

Open pauloney opened 4 months ago

I get an error when running the following example which seems to show an incompatibility between {eepic} and {showframe}:

\documentclass{report}

\usepackage{eepic}
\usepackage{showframe}

\begin{document}
This is a test.
\end{document}

The cause of the problem: showframe uses the ability to specify a dimension (number with unit or dimension register) for the \line command, as the LaTeX kernel has offered for some time. eepic redefines \line so that only a dimensionless parameter is allowed. Therefore, the following example produces the same error without showframe:

\documentclass{report}

\usepackage{eepic}

\begin{document}

\begin{picture}(2cm,2cm)
   \put(0,0){
     \line(1,1){2.83cm}%
   }%
\end{picture}

This is a test.
\end{document}

A solution would probably be to load the picture package after eepic:

...
\usepackage{eepic}
\usepackage{picture}
...

However, you should consider whether it still makes sense to use the outdated eepic package these days. There are plenty of better alternatives, such as pict2e, tikz or pstricks.
