[Tex/LaTex] tikzposter text justification in blocks

tikz-pgftikzposter

I have started to use the tikzposter class and I wonder why the text inside blocks is flushed left by default instead of justified. How can I change the text alignment in blocks to be fully justified?

Best Answer

basically you don't like line 426 which says

        {\large\color{blockbodyfgcolor}#3}

If it said

        {\large\rightskip\z@skip\spaceskip\z@\xspaceskip\z@ 
                               \color{blockbodyfgcolor}#3\par}

then you would get justified text (and fix the \par issue of your other question. It's a bit inconvenient to patch that you could just edit a local, renamed, copy and use that instead, or simpler just put

       \rightskip0pt
       \spaceskip0pt
       \xspaceskip0pt

at the start of your block entry, and

     \par

at the end. (The need for \par is a bug in the class file really, so you could report that)

If you do want to patch it, egreg suggests:

\documentclass{tikzposter}
\usepackage{xpatch}
\makeatletter
\xpatchcmd{\block}
  {\large\color{blockbodyfgcolor}#3}
  {\large\rightskip\z@skip
   \spaceskip\z@\xspaceskip\z@
   \color{blockbodyfgcolor}#3\par}
  {}{}
\makeatother

which would save editing a local copy of the class.

[Tex/LaTex] Bottom-aligning columns with tikzposter

I ended up solving it myself. Below is the code I used; if you put it in myposter.sty then use \usepackage[colalign]{myposter} to enable the alignment.

It works by saving the natural heights of all columns into the aux file, along with how many blocks there are. Then next compilation, for each column, it looks at the difference between the stored height and the maximum stored height, divides that by the number of blocks, and adds that much padding inside each block (at the top and bottom.)

\usepackage{letltxmacro}
\usepackage{ifthen}

\newif\ifmy@colalign
\my@colalignfalse

\DeclareOption{colalign}{
    \my@colaligntrue

    % Store the natural height and number of blocks of the current column in the aux file

[Tex/LaTex] Long title in tikzposter

The problem is that tikzposter puts the title inside a \scalebox thus preventing line breaks. You can recover line breaking placing your title inside a \parbox:

\documentclass{tikzposter}

\title{\parbox{\linewidth}{\centering This is a really  really  really  really  really  really  really  really  really  long title for a poster}}
\institute{The Institute}
\author{The Author}
\titlegraphic{Logo}
\usetheme{Basic}

\begin{document}

\maketitle
\block{BlocktitleA}{Blocktext}
\begin{columns}
\column{0.3}
\block{BlocktitleB}{Blocktext}
\column{0.7}
\block{BlocktitleC}{Blocktext}
\note{Notetext}
\end{columns}

\end{document}
