I want to include in a Lyx document an Xfig figure with some LaTeX formulas. Following this guide I can do this in ordinary .tex documents: I export my Xfig figure as a "Combined PDF/LaTeX (both parts)" file and I simply include it in the .tex document with the \input{file_name.pdf_t}
command. So far so good! Anyway, when I try to do this same thing in my Lyx document (both writing explicitly the \input{ }
command and through the Insert->File->Child_Document
menu) I get the following error:
\includegraphics {file_name.pdf}% The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g.,
\hobx'), type
I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined.
So, does someone now how to fix this? How can I include my figures with latex equations into Lyx?
Thank you all in advance!
\input
a pdf file directly into a latex document. the\includegraphics
command as cited in the error message is the proper method.\input
, file_name.pdf_t, is not a .pdf but an ordinary text file. To be more precise,file_name.pdf_t
is a .tex file of the form\begin{figures} ... \includegraphics{file_name.pdf} ... \end{figures}
, which tells latex to take the (real) .pdf file, file_name.pdf (without equations), and display on it some latex equations..!
