La barra de navegación del Beamer es demasiado larga

Question

Mi barra de navegación en Beamer es demasiado larga debido al formato actual. He considerado ir a varias líneas para la navegación circular, pero esto hace que el espacio vertical de la barra de navegación ocupe demasiado espacio. Creo recordar que en algún momento vi una presentación en la que los círculos se colapsan en un solo círculo, a menos que estén dentro de la subsección actual donde se expanden nuevamente para tener puntos para cada cuadro en ese punto.

Agradecería sugerencias sobre cómo mantener la barra de navegación de una sola línea como la que tengo, pero también sobre formas de condensar la barra para que se ajuste al ancho que tengo.

También creo recordar haber visto una presentación en la que había líneas entre los marcadores circulares de navegación para cada subsubsección de la presentación, pero todavía no he podido encontrar algo sobre cómo hacerlo. Si pudiera indicarme dónde podría estar ubicado, sería genial.

Gracias de antemano.

Answer 1

Los mini marcos de plantilla de proyector tienen 3 plantillas predefinidas:

• [default]muestra pequeños círculos como mini marcos
• [box]muestra pequeños rectángulos como mini marcos
• [tick]muestra pequeñas barras verticales como mini marcos

Entonces, por ejemplo, podrías simplemente cambiar a la tickplantilla, ya que no ocupa tanto espacio:

\setbeamertemplate{mini frame}[tick]
\setbeamertemplate{mini frame in current subsection}{tick}

Pero parece que quieres mantener los círculos. Entonces, ¿por qué no simplemente reducirlos? Para ello hay que redefinir las mini frameplantillas. Así que simplemente copié la defaultplantilla, le cambié el nombre scaled circlee introduje un factor de escala.

\defbeamertemplate{mini frame}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
    \pgfsetlinewidth{#1 * 0.4pt}
    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{fill,stroke}
  \end{pgfpicture}%
}
[action]
{
  \newlength{\myminiframesize}
  \setlength{\myminiframesize}{0.14cm}
  \newlength{\myminiframeoffset}
  \setlength{\myminiframeoffset}{0.03cm}
  \setbeamersize{mini frame size=#1\myminiframesize,mini frame offset=#1\myminiframeoffset}
}

\defbeamertemplate{mini frame in current section}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
    \pgfsetlinewidth{#1 * 0.4pt}
    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{stroke}
  \end{pgfpicture}%
}

\defbeamertemplate{mini frame in current subsection}{scaled circle}[1]
{%
  \begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
    \pgfsetlinewidth{#1 * 0.4pt}
    \pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
    \pgfusepath{stroke}
  \end{pgfpicture}%
}

Luego puedes simplemente cargarlo con

\setbeamertemplate{mini frame}[scaled circle]{0.7}
\setbeamertemplate{mini frame in current section}[scaled circle]{0.7}
\setbeamertemplate{mini frame in current subsection}[scaled circle]{0.7}

¿Dónde 0.7está el factor de escala?
