Hi,

I just want to know if there is any tool to convert a pdf (generated by latex or context) to latex source or context source file. Does anyone have got an experience on that?

I'm thinking about two alternatives: * libraries for reading like podofo and custom script for passing pdf context (text) to context commands * pass pdf to jpg, and apply http://detexify.kirelabs.org/classify.html for passing to tex symbols.

For me it's vital to pass mathematical symbols like (\int) to tex symbol and not like utf-8 symbols.

Thanks a lot, Xan.

Have you seen the mudraw program of mupdf http://www.mupdf.com/ ? It has a -t switch that outputs txt and a -tt and -ttt switches that output xml.

Thank you for answering and sorry for delay. I will check it, but I suspect that if I have $$\int_{i=1}^{\infty} x^2$$ in one latex document and it generates pdf, then mupdf -t of that document does not generate that formula, else "S i=1 x²". Thanks, Xan.
