I have two columns
in a top-aligned frame
which I want to be top-aligned as well. One column
is an itemize
environment, the other column
includes a graphic via includegraphics
.
I read in the beamer
manual that the T
option should be used when strange things happen. This is why I preferred to have T
as a default option, but that is not a good idea as it does not result in proper top-alignment.
See the following example:
\documentclass{beamer}
% dummy text macro
\newcommand{\mylipsum}{bla bla bla bla bla bla bla bla bla bla bla bla bla bla}
\begin{document}
\begin{frame}[t]{A frame with 2 \texttt{columns}: \texttt{itemize} + \texttt{figure} }
\begin{columns}
\begin{column}{.5\textwidth}
\begin{itemize}
\item first item \mylipsum
\item second item \mylipsum
\item third item \mylipsum
\item fourth item \mylipsum
\end{itemize}
\end{column}
\begin{column}{.5\textwidth}
\includegraphics[width=\textwidth]{test_image.png}
\end{column}
\end{columns}
\end{frame}
\begin{frame}[t]{A frame with 2 \texttt{columns [T]}: \texttt{itemize} + \texttt{figure} }
\begin{columns}[T]
\begin{column}{.5\textwidth}
\begin{itemize}
\item first item \mylipsum
\item second item \mylipsum
\item third item \mylipsum
\item fourth item \mylipsum
\end{itemize}
\end{column}
\begin{column}{.5\textwidth}
\includegraphics[width=\textwidth]{test_image.png}
\end{column}
\end{columns}
\end{frame}
\end{document}
Surprisingly, the case with the option T
results in worse top-alignment, as can be seen when comparing the two figures (adding T
actually shifts the columns
down…).
Why is the option T
shifting the columns
down and what am I missing here?
I am not sure if it plays a role, but here are the versions of beamer and XeTeX I am using (according to the output when compiling with xelatex
):
This is XeTeX, Version 3.14159265-2.6-0.99992 (TeX Live 2015/Debian)

Edit: I do not think that this question is a duplicate of that one as suggested: First of all, none of the answers solves the problem presented here and the problem here is specifically about the weird behavior of the T
option.

With
\begin{columns}[T]
the columns are only top aligned relative to their top edges. But below the top edge of anitemize
environment their is still a vertical distance of either\topsep
or\partopsep
. So you not only need to align thecolumns
but also remove this distance. Stefan's answer to the linked question defines an environmentmyitemize
to do so:
