You want transparency? Method 1 (*):

Your logo must be in eps or ps format and must be already transparent.
 (I think APS ghostcript can convert mostly any picture into eps transparent, I am not sure how though).  You also need ghostview (free).

·       Open Ghostview  and open your logo file.

·       Under File, select Convert.

·       Make sure the PDFwrite is selected

Click Ok, and select a name for your pdf-file.

You want pdf transparency? Method 2(*):

(Latex (free) and WinEdt (shareware) required.

Now there is another way of converting a logo (your logo might not be transparent)

from eps or ps to pdf, the advantage is that your logo becomes transparent automatically: Suppose your logo has a name: dolphin and it is located at c:\peter\dolphin.eps

(in the following example I added a word to my logo to create a new logo) This is what you need to do:

1.   Latex the following file and name it logo.tex

\documentclass[12pt]{article}

\usepackage{epsfig}

\setlength{\textheight}{24.5cm}

\newcommand{\logo}{\epsfig{figure=c:/peter/dolphin.eps,width=100pt}}.

\begin{document}

\pagestyle{empty}

\ \vspace{19cm}

\begin{tabular}{cc}

\hspace{-3cm}  $\logo$ & \begin{tabular}{c}

            {\hspace{-.4cm}\Huge \textbf{ I love Dolphins}}  \  \\ \\ \\

          \end{tabular}

\end{tabular}

\end{document}

2.   Once you are satisfied with the output, do a dvitopdf under winedt: Done! Your logo is now logo.pdf and it is pdf-transparent!!!!!!!!!! (If this option works for you and you love it, send me an e-mail to Jorge.garcia@csuci.edu, it is my invention)

3.   Note: I think you can also achieve the same even if you file is in jpg format, but instead of using  {\epsfig{figure=c:/peter/dolphin.eps,width=100pt}} you will

Use the corresponding instruction to include pictures in jpg format.

There is another way of transforming pictures in any format into pdf format, via the following web-site: http://www.online-utility.org/image_converter.jsp?outputType=PDF
