Hi everyone,
I have just made a new Inkscape extension. See
https://launchpad.net/svgtextext-to-pdflatex
The purpose of this Inkscape extension is to export Tex Text objects as real LaTeX code, not just paths. This way, the typeface can be changed from the LaTeX document without having to regenerate all the Tex Text objects inside the figure in Inkscape. It also ensures consistency with the fonts used in the rest of the LaTeX document, and furthermore, it is possible to cross-reference other parts of the document from within the figure.
The extension has been tested in Ubuntu with pdf2svg installed. To install it, download the two source files, put them in ~/.config/inkscape/extensions and restart Inkscape. This will add a menu entry to Extensions > Export.
