Off-topic: Convert PDF to (Con/La)TeX

[Xan]

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.

Note: pdf could be substitute for ps if you want ;-)

PS: Please CCme

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.
