[texhax] Slides -> Poster

[Ricardo Lima]

Steve,
Thank you for your email.
Of course that I understand that better questions get better answers. I was not giving examples because most of the questions were conceptual. I am not expecting you to correct a wrong "{" or a package declaration in a wrong place.

Regarding the background set, I used three approaches:
1- \pagecolor{black} (yes I followed the manual)
2- and the eso-pic:
\newsavebox{\background} 
\sbox{\background}{\includegraphics[width=40cm,keepaspectratio=T]{gklogo.jpg}}%
\AddToShipoutPicture{%
\AtPageCenter{\makebox(0,0){\usebox{\background}}}%
}

Even with the eso-pic approach, what is happenning is that with the white slides the background is over the white background of the slides, but here are the examples:

http://paginas.fe.up.pt/~rlima/poster/poster.tex

What I was looking for was a solution that will not overlap the white slides. 
Thanks in advance for your help.

Firstly, for the second and last time, you get better answers if you
show us what you did rather than describe the results. Assemble a small,
minimal example and include the latex source. There are lots of ways to
try to do what you are doing, and it is impossible for us to guess.

I suspect your problem is that whatever you are using to set a
background colour sets (or more accurately perhaps RE-sets) the pdf
document's background colour, so that anything in your pdf that is
"background" ends up in that colour. Actually, most of the time that is
what people would want to happen if you think about it, because it
CHANGES the background colour to the new colour.

You might try the suggestion I've already made, namely to use eso-pic to
put a PICTURE in the background instead of setting a background colour.
I haven't tried it, but it should be as simple as creating a box as big
as your page filled with whatever colour you wish, e.g, using the
picture environment. Or (as I thought you were trying to do because you
didn't tell us) you can put a real graphic of some kind there.
