Hello, I have made a diagram in xfig in ubuntu and exported it in the form of latex and it gave out the following code :

Code: Select all

\setlength{\unitlength}{4144sp}%

\gdef\SetFigFont#1#2#3#4#5{%

  \selectfont}%
\fi\endgroup%

\end{picture}%

I just want to know that is there a way through which I can insert this code into my existing LaTeX document to give out that same image ?

[Johannes_B]

It is easier than you expect it to be, just copy the code inside.
The code as it was was resulting in a figure very big, so i made the unitlength smaller. The code is very hard to read and requires package color (or xcolor) to print black lines, which is a bit ridicoulus. Package pgf (TikZ) can be very helpful in making little schemes, flowcharts and diagrams. The documentation has a great tutorial and it is worth a look.

Thanks. Using package color or xcolor does the job. However, the link you provided to the TikZ package gave out the following message :
The re­quested URL /pkg/TikZ was not found on this server.
Also, which LaTeX software should I use ? Currently I am using Gummi. Which one do you use and which one would you recommend me using ?

[Stefan Kottwitz]

The official package name for TikZ is pgf. You could use this link. You could also have a look at the TikZ example gallery.

Btw. I am using TeXworks as LaTeX editor on Ubuntu, and I'm very satisfied with it.

I was a bit in hurry writing this, and forgot about the little discrepancy.

I would recommend using texworks as well, it is a very simple editor, nothing to distract a new user. I meself am using vim to edit my texts. The most important thing is feeling comfotable with ones editor in use.
