Insert LaTeX equations in Inkscape

Trick source

"Recent versions of Inkscape (since 0.48?) have built-in support for including a LaTeX formula inside a drawing. It is on the menu bar: Extensions->Render->LaTeX Formula. This menu might be hidden if Inkscape cannot find these helper programs: latex, dvips, pstoedit. On Ubuntu, you can install these programs with the command,

$  sudo apt-get install texlive pstoedit

Alternatively, you can use the textext extension. It is similar to the build-in LaTeX support, but has a slightly more polished input interface."
