[Tex/LaTex] EPS figures are pixelized in the final PDF with LyX

epslyxpixelated

This is the first time that I compile a LyX file with some EPS picture inside on my current computer. I already did that before on other computers, without any problem.

But here, the result is pixelized. All the document can be compiled, and is rendered nicely, but the EPS file is pixelized. I know it is not due to my EPS file which is really in vectorial format because I can open it with other readers and zoom inside without any problem.
Result :

I tried to figure out which options I should activate or which converter I have to set but didn't find anything.
This guy had the same problem than me : Link but I think he is working on a Windows OS while I am on Mac OS, and the resolution don't seems to work for me.

EDIT : I tried for instance to set EPS to PDF (ps2pdf). The result is no longer pixelized but… takes the whole page, as a PS file. Here is an image of the result and the parameters :

EDIT again : Trying to use epstopdf is not working, image still pixelized, but maybe I don't use the correct parameters ? I was expecting something as 'PDF (epstopdf)' in the list but there is none of these.

I had to use the package epstopdf and to correctly configure the converter in LyX preferences. Then, reconfigure a bunch of times (it didn't work the first time...) but after doing the usual steps (quit and start the program again and so on) it worked. Thanks to JLDiaz for the answer !

Simulator

Try the following to diagnose your problem.

% simulator.tex
\documentclass[preview,border=12pt]{standalone}
\usepackage{filecontents}

\begin{filecontents*}{input.tex}
\documentclass[preview,border=12pt]{standalone}
\usepackage{tikz}
\begin{document}
This is a TikZ output.
\begin{tikzpicture}
    \draw (0,0) circle (2);
\end{tikzpicture}
\tikz\fill[red] (0,0) ellipse (3pt and 5pt); is an ellipse. 
\end{document}
\end{filecontents*}

\immediate\write18{pdflatex input}
\immediate\write18{pdftops -f 1 -l 1 -eps input.pdf output.eps}

\usepackage{graphicx}
\begin{document}
I am importing EPS image.\\
\includegraphics{output}
\end{document}

enter image description here

Compile the code above with

latex -shell-escape simulator
dvips simulator
ps2pdf -dAutoRotatePages=/None simulator.ps

As ps2pdf sometimes rotates the output automatically, please use -dAutoRotatePages=/None to prevent it from doing such an unwanted rotation.

If you are using Windows, use # instead of = in -dAutoRotatePages=/None because = has a special meaning for batch files in Windows.

Very important notes

If you use opacity in your TikZ code (PSTricks code as well), for example,

\documentclass[preview,border=12pt]{standalone}
\usepackage{tikz}
\begin{document}
This is a TikZ output.
\begin{tikzpicture}
    \draw (0,0) circle (2);
\end{tikzpicture}
\tikz\fill[red,fill opacity=.5] (0,0) ellipse (3pt and 5pt); is an ellipse. 
\end{document}

then you will get a rasterized output as follows.
