# Put text in any shapes with automatic line breaking in TikZ?

I notice that we can put text in a circle by

\node[draw,circle]{Text};

Is it possible to put text in any shapes with automatic line breaking? (e.g., in an ellipse, or in a closed curve that we draw)

EDIT

For the demand of "putting text in any closed curve we draw" is probably a duplicate of Fitting text to a shape in TikZ (\shapeparnode is used), though I'm looking forward to a shape option of \node that uses a closed curve we draw.

Sure. SImply use text width with/without align:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes}

\begin{document}

\begin{tikzpicture}
\node[draw,fill=cyan!30,ellipse,text width=2cm]
{Some text goes here inside this ellipse};
\node[xshift=4cm,draw,fill=green!25,ellipse,text width=2cm,align=center]
{Some text goes here inside this ellipse};
\node[xshift=8cm,draw,fill=yellow!25,ellipse,text width=2cm,align=right]
{Some text goes here inside this ellipse};
\node[xshift=2cm,yshift=-3cm,draw,fill=orange!25,trapezium,text width=2cm,align=center]
{Some text goes here inside this trapezium};
\node[yshift=-3cm,xshift=6cm,draw,fill=magenta!25,regular polygon, regular polygon sides=6,text width=2cm,align=center]
{Some text goes here inside this hexagon};
\end{tikzpicture}

\end{document}

Regarding the part about putting text in any closed curve we draw, there might be a number of possible approaches here:

• The \shapeparnode command defined by Paul Gaborit in his answer to Fitting text to a shape in TikZ.

• Defining a new shape as described in Section 75.5 Declaring New Shapes of the PGF manual (this is a non trivial process, which might be simplified by the using the package in the following item).

• Using the makeshape package to simplify the creation of new shapes. This is the abstract from the package documentation:

The makeshape package simplifies writing PGF shapes. Declaring a custom shape with a correct anchor border can be difficult. Complex shapes often need complicated calculations to find the touching point of a connecting line. This package only requires that a developer write a PGF path describing the anchor border. It also provides macros that help with the management of shape parameters and the definition of anchor points.

Thanks for your answer! What if we can to put some text in a closed curve that we draw rather than predefined shapes, Is it possible to define a "text region" by drawing a closed curve, and give it a name as myTextRegion? Finally we use it as \node[draw,myTextRegion, text width=2cm]{some text}; ? (or maybe without option text width, just let it fit myTextRegion automatically) –  Hongying Apr 20 '13 at 6:22
@Hongying I've added to my answer some possible approaches to deal with the "arbitrary closed curve". –  Gonzalo Medina Apr 20 '13 at 17:38
