Scale figure inside tikzfigure environment in tikzposter class

Question

I am trying to make my poster with the tikzposter class. I want to place a figure inside a block and I have to use the tikzpicture environment. But I can't scale the figure properly.

\documentclass[a0paper,landscape]{tikzposter}
\begin{document}
  \begin{columns}
     \column{0.25}
     \block{Introduction}{
       ...blabla...
      }
     \column{0.5}
     \block{Methods}{
       \begin{tikzfigure}
         \includegraphics[width=\columnwidth]{myfigure}
       \end{tikzfigure}
      }
     \column{0.25}
     \block{Results \& conclusions}{
       ...blabla...
      }
   \end{columns}
\end{document}

It appears that \columnwidth applies to the entire poster width and not to the column I am in, because my image spans the whole poster width. I don't like using pts or cms as width in `\includegraphics', I would like to use some relative measure. how can I do that inside tikzfigure?

Answer 1

I can't access the defined widths of the blocks properly, but you can use \linewidth.

\documentclass[a0paper,landscape]{tikzposter}
\usepackage{graphicx}
\begin{document}
  \begin{columns}
     \column{0.25}
     \block{Introduction}{
       ...blabla...
      }
     \column{0.5}
     \block{Methods}{
       \begin{tikzfigure}%
         \includegraphics[width=\linewidth,draft]{Temp.png}%
       \end{tikzfigure}
      }
     \column{0.25}
     \block{Results \& conclusions}{
       ...blabla...
      }
   \end{columns}
\end{document}
