I am trying to insert an image from Inkscape. I saved it as a pdf, checking the PDF + Latex option.
Inside my Latex file, I wrote the following code :


but when i try to compile using pdflatex, it gives me the following error message:

ERROR: Undefined control sequence.  

--- TeX said ---  
<argument> \includegraphics  
                            [width=\unitlength ]{topo4serv.pdf}
l.52 ...raphics[width=\unitlength]{topo4serv.pdf}}

In the output pdf file the text of the svg file is there but not the shapes...
If someone has an answer i would be very grateful.

  • First time I am seeing something like topo4serv.pdf_tex. I would rather say \includegraphics{topo4serv.pdf}

  • @azetina Usage seems correct as it is stated here: tug.ctan.org/tex-archive/info/svg-inkscape

    It is correct to use \input{file.pdf_tex}. If you open that file, it has instructions for its usage. Like egreg said, you need to have \usepackage{graphicx} in your preamble for this to work. Commented Jun 29, 2012 at 17:45

\includegraphicsis giving error because it is not defined, which means you need to \usepackage{graphicx} on document's preamble
