# Beamer: Line separator in column

I am using pgfornament to draw line separators.

It works perfectly, but in this case, I want to place the line separator inside a column, but I get errors...

This is the MWE I made:

\documentclass[xcolor={dvipsnames,table}, hyperref={unicode}]{beamer}
\usepackage{etex}
\reserveinserts{28}
\setbeameroption{hide notes}

\mode<presentation> {
\usetheme{Singapore}
\usecolortheme{orchid}
\usepackage[dvipsnames]{xcolor}%before tikz
\usepackage[absolute,overlay]{textpos} %for positioning
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{graphicx} %Allows including images
\setbeamertemplate{navigation symbols}{} % To remove the navigation symbols from the bottom of all slides uncomment this line

decorations.pathreplacing}%calc is already called in the beamerthemeSIgN.sty file!
\usepackage{pgfplots}
\pgfplotsset{compat=1.7}%http://tex.stackexchange.com/questions/81899/what-does-running-in-backwards-compatibility-mode-mean-and-what-should-i-fix-t

\usepackage{multicol}
\usepackage{multirow}

%line separator
\usepackage[object=vectorian]{pgfornament}
\newcommand{\sectionline}[3]{%
\nointerlineskip \vspace{.5\baselineskip}\hspace{\fill}{
\resizebox{0.5\linewidth}{#3}{
\pgfornament[color = #1]{#2}
}
}
\hspace{\fill}
\par\nointerlineskip \vspace{.5\baselineskip}
}

\usefonttheme{serif} % default family is serif
\usepackage{fontspec}

\usepackage{lmodern}% http://ctan.org/pkg/lm
\defaultfontfeatures{Mapping=tex-text}
}

\begin{document}

\end{column}%
\end{columns}

This MWE produces this.

However, I want the line separator NEXT TO the image, NOT UNDER it...

If I place the line separator inside the column I get the error:

You can't use \prevdepth' in horizontal mode.

Any help?

• I don't understand your code. But I've seen that second \nointerlineskip was preceded by \par and first not. Adding it before first \nointerlineskip your code compiles. Although I don't know if the result is what you want. Jun 8, 2016 at 7:23

The error message is ! You can't use '\prevdepth' in horizontal mode. You may add a blank line before \sectionline to leave horizontal mode or, as suggested by Ignasi's comment, you may add \par before the first call to \nointerlineskip into the definition of \sectionline.

• Oh that easy? Why wasn't I aware of this? Many thanks!! Jun 8, 2016 at 7:33
• Are your answer and my comment equivalent solutions? Jun 8, 2016 at 10:42
• @Ignasi A blank line and \par` are equivalent. But your solution seems more robust in current context. Jun 8, 2016 at 11:09
