  An \texttt{opacity-pro} Demo File\\[3pt]D. P. Story
\end{center}

The \textsf{opacity-pro} pretty much needs distiller with
the \textsf{Adobe PDF Settings} set to process the transparency
operator. For your convenience, the \textsf{Adobe PDF Settings} file
\texttt{Standard\_transparency.joboptions} is included in the
distribution. Place this file wherever distiller looks for the
\texttt{.joboptions} files.\footnote{Go to \texttt{Settings > Edit
Adobe PDF Settings ...} in the Distiller application window, then
click the \texttt{SaveAs} button. A \textsf{Save Adobe PDF Settings
As} dialog box opens, and you can then see where Distiller likes to
save its \texttt{.joboptions} file. Copy the provided
\texttt{.joboptions} to the folder and restart Distiller, the
\texttt{Standard\_transparency} should now be visible in the drop
down \textsf{Default Settings} list.}

The yellow and blue boxes are under the picture, which has opacity
of 0.5 and the text which has opacity of 0.3, and blend type
\texttt{Normal}, the default. The green and magenta boxes are on top
the picture with opacity of 0.4 and blend type of \texttt{Lighten}.


\bigskip\noindent
This demo file uses only the most basic of packages: \textsf{color},
\textsf{graphicx} and \textsf{opacity-pro}. The other demo files
assume the use of the \textsf{web} package, some use the
\textsf{graphicxsp} package. Be sure to download all the latest
versions of these.
