I want to create a multi part parallelogram input block for a flowchart. There is no multi part trapezium shape that exist so for now I used a standard rectangular multi part shape with the xslant option to make it look like a parallelogram. I defined a style that I can easily reuse.

The problem is that the text is also slanted, and if possible I would like it normal.

Is there a way to apply xslant only to the shape and not to the text ?

I tried creating a second node only for the text but the problem is that the paralellogram doesn't resize properly to fit the text.

My MWE :

\documentclass[class=article]{standalone}
\usepackage[]{xcolor}
\usepackage{tikz}
\usetikzlibrary{shapes}

\tikzstyle{io} = [rectangle split,  rectangle split parts=2, xslant=0.4,
draw, rectangle split part fill={blue!50,blue!20}, text centered, minimum width=4.25cm, minimum height=2cm]

\begin{document}
\begin{tikzpicture}

\draw (0,0) node[io,name = ,align = center]{Parameters\nodepart{two} $\alpha$, $\eta$};

\end{tikzpicture}
\end{document}

Thanks for your help.

  • You could create your custom node shape Commented 14 hours ago
  • Or maybe instead of a node define a pic and adjust the size of the slanted rectangles using the fit library … Commented 13 hours ago

You could put the node texts in boxes that you "unslant":

\documentclass[border=10pt]{standalone}
\usepackage{tikz, l3draw}
\usetikzlibrary{shapes}

\ExplSyntaxOn
\NewDocumentCommand { \unslant } { m m } {
    \draw_begin:
        \hbox_set:Nn \l_tmpa_box {#2}
        \draw_transform_xslant:n {#1}
        \draw_box_use:N \l_tmpa_box
    \draw_end:
}

\ExplSyntaxOff

\tikzset{
    io/.style={
        rectangle split,
        rectangle split parts=2,
        xslant=0.4,
        draw,
        rectangle split part fill={blue!50, blue!20},
        text centered,
        minimum width=4.25cm,
        minimum height=2cm
    }
}

\begin{document}
\begin{tikzpicture}

\draw (0,0) node[io] {
    \unslant{-0.4}{Parameters}
    \nodepart{two}
    \unslant{-0.4}{$\alpha$, $\eta$}
};

\end{tikzpicture}
\end{document}

output of above code

Note that you should not use the deprecated command \tikzstyle.
