How to include `tikzpicture` in forest node?

Question

How to include tizpicture, for example defined in ducks package, to a forest node?

Edit: Simplified MWE with comparison result using duck in tikzpicture and in forest.

\documentclass[border=3.141592]{standalone}
\usepackage{forest}
\usetikzlibrary{ducks}

\begin{document}
\tikz[baseline]{\duck[signpost=1]}\quad
    \begin{forest} 
[\tikz{\duck[signpost=1]}]
    \end{forest}
\end{document}

As you can see, the duck image in forest node is not complete, missed is result of option signpost=1.

I guess, that image is included before its process of duck drawing is complete. So far I didn't find a way how to delay inclusion of image, or better, how to correct include such images in forest node.

Answer 1

you can add tikz pictures with the tikz key. But you will have to adapt the spacing and the positioning:

\documentclass[border=3.141592]{standalone}
\usepackage{forest}
\usetikzlibrary{ducks}

\begin{document}

    \begin{forest}
for tree = {
% nodes labels
/tikz/every label/.style = {label distance=0pt, inner sep=0pt},
% tree setings
    anchor = south,
     edge = {-, semithick, shorten < = 1em},
    s sep = 30mm,
    l sep = 30mm,
            }
[Text,tikz={\duck[shift=(.north)]},
   [Text,tikz={\duck[shift=(.north),signpost=1]}] % processed
   [Text,tikz={\duck[shift=(.south west),graduate=gray!20!black, tassel=red!70!black]},
    ]
]
    \end{forest}
\end{document}
