Re: Background image in Beamer

[Eugenio Guevara]

After some help from Till Tantau, and consulting every related document I 
could find, including de Lyx page, I developed an approach that works (?) 
for me including the following commands in the preamble:

\newcommand\BackgroundPicture[1]{%
   \setbeamertemplate{background}{%
   \parbox[c][\paperheight]{\paperwidth}{%
       \vfill \hfill 
\includegraphics[width=0.8\paperwidth,height=0.8\paperheight]{#1}
        \hfill \vfill
     }}}

and using the command
\BackgroundPicture{image}
before the slide I need the background in.
I did the image processing with ImageMagick 1.6.9 tools, in order to 
"reduce" the intensity of the image in the background (dissolving an image 
onto a white background of the same size)

Any more contributions are accepted
Thanks

Hi Eugenio
I have been looking for an answer to this myself so I  waited hoping 
someone would answer your query.
The nearest I have got is putting a grid in according to the manual on 
page 59 which also mentions that one can put a picture in using the 
\setbeamertemplate{background}

For putting a grid in one just goes:
\setbeamertemplate{background}[grid]
according to the manual one can put in a background picture the same way 
but it gives no example how and all my attempts have not been very 
successful.

Perhaps someone more adroit at interpreting the manual will be kind enough 
to explain.

I am using Beamer with Lyx 1.3.5 on a Windows XP platform.  I am 
preparing
a
presentation and can't find a way to put a background image on any frame 
and
change it as needed.

Can anyone give some light on this matter?
Thanks in advance
