How to remove the two columns that form the LATEX "Article" style for a single page

  • 772

I am doing an article with two columns in Latex and in the Appendices instead of putting the title and then the image, 2 titles are put on one page and then the images on the others. It is not a problem of sizes because I have tried with everything and nothing, also specifying [h!] and [htb]. I attach photos of how it is now and how I would like it to be (marked in red in the image):

Title page only:

page with title only

Image only page:

page only with the image

Code:

\subsection{Casos de Uso}
\label{casosuso}

\begin{figure*}[ht]
\begin{minipage}[b]{0.45\linewidth}
\centering
\includegraphics[width=\linewidth]{img/CasosUsoAdmin.png}
\caption{Diagrama de casos de uso - Administrador.}
\label{casoadmin}
\end{minipage}
\hspace{0.5cm}
\begin{minipage}[b]{0.45\linewidth}
\centering
\includegraphics[width=\linewidth]{img/casosUsoUser.png}
\caption{Diagrama de casos de uso - Usuario.}
\label{casouser}
\end{minipage}
\end{figure*}

\newpage 
\subsection{Diagrama E-R}
\label{diagramaer}
\begin{figure*}[ht]
\centering
    \includegraphics[width=1\textwidth]{img/DiagramaER.png}   
    \caption{Diagrama E-R de la Base de Datos.}
    \label{er}
\end{figure*}

\end{document}

Any ideas?

    The short answer is that you can't use figure*, because Wikipedia ( LaTeX/Floats, Figures and Captions , Section: Wide figures in two-column documents ) mentions the following:

    A bad point of those environments is that they can be placed only at the top of the page or on their own page [...]

    Possible solution

    One viable option I found was to manually adjust the images to get the following result: enter image description here

    Code

    This was using:

    \documentclass[twocolumn]{article}
\usepackage{graphicx}
\usepackage{lipsum} % No es necesario, solo para generar texto aleatorio

\begin{document}
    \subsection{Casos de Uso}
    \begin{figure}[h]
        \begin{minipage}{2\linewidth}
            \begin{minipage}[b]{.5\linewidth}
                \includegraphics[width=\linewidth]{img/Dia1}
                \caption{Diagrama de casos de uso - Administrador.}
            \end{minipage}\hfill
            \begin{minipage}[b]{0.45\linewidth}
                \includegraphics[width=\linewidth]{img/Dia2}
                \caption{Diagrama de casos de uso - Usuario.}
            \end{minipage}
        \end{minipage}
    \end{figure}
    \textbf{Texto del Caso de Uso}\\ % No es necesario
    \lipsum[1-2] % No es necesario
    \newpage
    \subsection{Diagrama E-R}
    \begin{figure}
        \vspace*{7.5cm} % Ajuste manual
        \includegraphics[width=\linewidth]{img/Dia3}
        \caption{Diagrama E-R de la Base de Datos.}
        \label{er}
    \end{figure}
    \textbf{Texto del Diagrama E-R}\\ % No es necesario
    \lipsum[4] % No es necesario
\end{document}
