#4 Multiple pictures and a white box

[Anonymous]

Hi,

I am trying to create a slide which uses the autumn
background with the prosper package and has several
postscript files on the same
slide.

To make the pictures clear, I added a white box and
inserted the figues using the tabular command. The
latex syntax is as follows

\overlays{1}{%
\begin{slide}{\small Dispersive Considerations 1 $h$
refinement}
\onlySlide*{1}{
\setlength{\unitlength}{1in}
\begin{center}
\colorbox{white}{\makebox(3,2.5)[t]{
\begin{tabular}{cc}
{\includegraphics[height=1in,width=1.2in,keepaspectratio=true]{disper1hq.eps}}
&
{\includegraphics[height=1in,width=1.2in,keepaspectratio=true]{disper0.5hq.eps}}
\\ \hbox{$h=1$} & \hbox{$h=0.5$} \\ {\includegraphics[height=1in,width=1.2in,keepaspectratio=true]{disper0.25hq.eps}}
&
{\includegraphics[height=1in,width=1.2in,keepaspectratio=true]{disper0.125hq.eps}}
\\ \hbox{$h=0.25$} & \hbox{$h=0.125$}
\end{tabular}}}
\end{center}}%
\end{slide}}

The slide appears fine in the normal view of acrobat
reader, however, when I change to full screen mode,
additional black lines appear and the figures are no
longer visible.

When I use only one postscript file, set against a
white background
I do not get this problem....

Thanks
