I created it by myself using TeTex, Ghostscript, Sketch and Inkscape, working in Linux. If you want to create it, too, follow these steps:

• create the following LaTeX source:

% !TeX TS-program = pdflatex
% !TeX encoding = UTF-8
% !TeX spellcheck = en_US
% !BIB TS-program = bibtex
%PDFLaTeX
%LaTeX=>PDF
\documentclass[a4paper,12pt]{article}

\begin{document}
\thispagestyle{empty}
\begin{huge}
\LaTeX
\end{huge}
\end{document}

and save it under LaTeX_logo.tex

• compile the PDF version running

pdflatex LaTeX_logo.tex

• create the Postscript version using

pdf2ps LaTeX_logo.pdf

• now you have to convert the Postscript version into the SVG format. If you have Sketch installed, you can create your own script following the guidelines in this guide. After you have created the script, simply run:

ps2svg.sh latex_logo.ps

• now you have your SVG version to post-process to obtain the image.
