svg to tex with svg package and inkscape: make the text to wrap inside a shape

Question

I use LuaLaTeX (up to date MikTeX +TexStudio) and wish to use SVG illutsrations in my document, which are created in MS Visio. here is the original image

As a quick and dirt fix to my problem with svg package I launch inkskape manually with batch file in same manner as svg package is supposed to do it

@echo off
"C:\Program Files\Inkscape\inkscape.exe" -z -D -f %1 -A "%~dpn1.pdf" --export-latex

and compile the document. Here how it looks in the pdf.

It looks quite good: the shapes are correct, the font adjusted to the font of the document and enlarged where appropriate. Except it doesn't wrap around to a new line inside the shape.The attempt to force the line break with \newline is ignored. here is the content of pdf_tex file

Is there a way to fix it? May be with some additional LaTeX code in the image?

Answer 1

You could manually split the text in two lines:

\documentclass{article}

\usepackage{graphicx}
\usepackage{xcolor}

\begin{document}

\setlength{\unitlength}{497.74924049bp}%
\begin{picture}(1,0.40658965)%
  \put(0.06182823,0.21124862){\color[rgb]{0,0,0}\makebox(0,0)[lb]{\smash{{\large Raspberry PI 2}}}}%
  \put(0.06182823,0.18){\color[rgb]{0,0,0}\makebox(0,0)[lb]{\smash{Reads the data and adjusts the current}}}%
\end{picture}%

\end{document}

Or you could wrap the in a \parbox of appropriate width to get automatic line breaks:

\documentclass{article}

\usepackage{graphicx}
\usepackage{xcolor}

\begin{document}

\setlength{\unitlength}{497.74924049bp}%
\begin{picture}(1,0.40658965)%
  \put(0.06182823,0.21124862){%
    \parbox{3cm}{%  
        {\large Raspberry PI 2}
        Reads the data and adjusts the current
    }%
  }%
\end{picture}%

\end{document}
