EPS figure in pdf output is transparent and placed over text - a Latex problem

I have generated eps figures in MATLAB an开发者_运维百科d am using them in Latex. (Miktex 2.9 with TexnicCenter).

I dont understand why the output ( PS-> pdf ) shows the figure on top of the text below it. Also the figure appears to have a transparent background through which you can see the text over which it is placed.

the name of the figure file is TEER.eps

Here is what I have in my code:

\documentclass[preprint,12pt]{elsarticle}
 \usepackage{graphicx}
 \usepackage{amssymb}

\begin{document}

\begin{figure}[!ht]
\begin{center}

\scalebox{0.4}{\includegraphics*[0.6in,10.4in][7.9in,4.7in]{imgs/TEER}}

\caption{TEER plot}
\label{fig:TEERplot}
\end{center}
\end{figure}
.

.
.

Kindly let me know what Im doing wrong. Thanks

When you use graphicx (which is recommended), you should use the form \includegraphics[width=...]{imgs/TEER}. You give the actually intended width to that; the image is automatically scaled. You could also give the height instead. In your case, it seems like you want something like

\includegraphics[width=2.92in]{imgs/TEER}

You can also use relative widths to the textwidth:

\includegraphics[width=\textwidth]{imgs/TEER}

or

\includegraphics[width=0.8\textwidth]{imgs/TEER}
