How can Tikzposter be used to create a poster with multiple pages?

Question

I'm trying to create a poster using Tikzposter with the following code:

\documentclass{tikzposter} % See Section 3
\input{Settings/Packages.tex}
\input{Settings/Administrative.tex}

\title{\myTitle} \institute{} % See Section 4.1
\author{Emanuel Enberg} \titlegraphic{\includegraphics[]{Files/MID_RGB.png}}
\usetheme{Autumn} % See Section 5
\usecolorstyle{Britain}

\renewcommand\thesection{}
\renewcommand\thesubsection{\arabic{subsection}}

\begin{document}

\maketitle
\begin{columns}


\column{0.37}% Width set relative to text width
\block{Abstract}{\input{Chapters/Sections/AbstractContents.tex}}
\block{Inledning}{\input{Chapters/Sections/Chapter1_Section1_Inledning.tex}}

\column{0.63}
\block{Syfte \& frågeställning}
{\input{Chapters/Sections/Chapter1_Section2_Syfte-och-fragestallningar.tex}}
\block{Bakgrund \& tidigare forskning}
{\input{Chapters/Sections/Chapter1_Section3_Bakgrund-och-tidigare-
forskning_Part1.tex}}

\begin{subcolumns}
    \subcolumn{0.465} 
    \block{Nervcell}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection1_Nervcell.tex}} 
    \block{Maskininlärning}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection2_Maskininlarning.tex}}

    \subcolumn{0.535} 
    \block{Vektorer \& matriser}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection3_Vektorer-och-matriser.tex}}
    \block{Artificiell neuron, del 1}{\input{Chapters/Sections/Subsections/Chapter1_Section3_Subsection4_Artificiell-neuron_Part1.tex}}
\end{subcolumns}

\end{columns}


%%%%%% HERE I WOULD NEED TO MAKE A NEW PAGE/POSTER


\end{document}

This code gives me the following output:

However, as you can see in the image, I can't fit all of the content on a single page. I figure I would need at least 3 pages in total.

So far I've tried using \newpage and placing more blocks after. However, that gives me with some nasty errors.

I have considered making separate documents for each page, but that would mean I can't reference figures and equations from other pages.

Is there any way to generate a poster with multiple pages using Tikzposter? If not, is there any other package with similar functionality to Tikzposter which would allow me to do so?

Answer 1

This shows how to use the xr package to link two tikzposters. The tricky bit was making the equation numbers continuous.

First poster (test5.tex):

\documentclass{tikzposter}
\usepackage{xr}
\externaldocument{test6}

\makeatletter
\AtEndDocument{\immediate\write\@auxout{\string\newlabel{lasteq}{{\arabic{equation}}{\thepage}}}}
\makeatother

\begin{document}
\block{First page}{\begin{equation}\label{first}
x=a
\end{equation}
See equation (\ref{second})}
\end{document}

Second poster (test6.tex):

\documentclass{tikzposter}
\usepackage{refcount}
\usepackage{xr}
\externaldocument{test5}
\AtBeginDocument{\setcounter{equation}{\getrefnumber{lasteq}}}
\begin{document}
\block{Second page}{\begin{equation}\label{second}
y=b
\end{equation}
See equation (\ref{first})}
\end{document}

Answer 2

No, there's not.

A tikzposter is basically a big tikzpicture, and that can't be broken across pages. Of course, multi-page posters doesn't make sense in the first place, so you should have less content, not more pages.

But you can have a look at baposter (http://www.brian-amberg.de/uni/poster/), which seems to allow for multiple poster environments, and thus multiple pages. Quick example:

\documentclass[a3paper]{baposter}
\usepackage{caption}

% set default options for poster(s)
\setkeys[ba]{posterbox}{
headerborder=closed,
headerColorOne=black!30,
headerColorTwo=black!50,
borderColor=blue
}
\setkeys[ba]{poster}{
bgColorOne=black!10,
bgColorTwo=black!20,
columns=2
}
\begin{document}
\begin{poster}{}
{}
{title}
{\textsc{Author}}
{}

\headerbox{Text}{name=text,column=0,row=0}{%
\captionof{figure}{Stuff \label{a}}
}
\end{poster}

\begin{poster}{
  headerheight=0pt % <- don't need space for title
}
{}
{}
{}
{}

\headerbox{Text}{name=text,column=0,row=0}{%
Ref to fig. \ref{a}
}
\end{poster}
\end{document}
