pdfcolparcolumns rulebetween does not work correctly #89

Open froschkoenig101 opened 2 years ago

froschkoenig101 commented 2 years ago

Under special circumstances, the rulebeween in pdfparcolmns is split into several short line segments. This bug occurs also in the parcolumns and parallel package. However, I would be verry happy, if at least pdfcolparcolumns would be usable.

Example showing the bug:

\documentclass[a4paper]{article} \usepackage{pdfcolparcolumns} \begin{document} \begin{parcolumns}[rulebetween=true]{2} \colchunk{1 \ $\frac{1}{2}$} \end{parcolumns} \end{document}

sorry I can't reproduce that. The rule looks perfectly fine, even at large zoom. How do you compile? Which viewer do you use? Is your system up-to-date?

I am using pdflatex under texlive2022. Sorry, when posting, github made my \\ to a \. The correct code is:

\documentclass[a4paper]{article} \usepackage{pdfcolparcolumns} \begin{document} \begin{parcolumns}[rulebetween=true]{2} \colchunk{1 \\ $\frac{1}{2}$} \end{parcolumns} \end{document}

Ah, well sorry I don't think that much can be done. Increase the \baselineskip so that the line is no longer pushed apart by the the fraction, or set \lineskip=0pt inside the environment.
