The idea is to make a background for the poster that fill all of it. But I have the following result

enter image description here

Even you can't see (by the background of the page), there is a white space (an horizontal space in whole the page). I tried to change with the posistion of \psframe but it doesn't work. I want to have all the background filled. I appreciate your help

Can you please make your code compilable, starting with \documentclass{...} and ending with \end{document}? –  karlkoeller Jul 2 '13 at 15:40
    
Done!. I put the whole code –  Alejandro Guarnizo Jul 2 '13 at 16:06
    
are you running xelatex? –  Herbert Jul 2 '13 at 19:12

use it this way for the background:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%               Background                     %%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\newcommand{\background}[3]{\leavevmode%

  \newrgbcolor{cgradend}{#2}%
  \psframe[fillstyle=gradient,gradend=cgradend,
  gradbegin=cgradbegin,gradmidpoint=#3]
  (-1in,3.5in)(\paperwidth,-\paperheight)}

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 %%%                Poster                        %%%

\newcommand{\pbox}[4]{%

I also deleted some spurious spaces.

Still the same problem..I compile with xelatex. Now I realize the problem is compiling with xelatex, and not with Latex, and then converting from dvi to pdf. Now the problem is to convert some transparents PNG figures to transparent eps. –  Alejandro Guarnizo Jul 3 '13 at 8:34
    
eps doesn't know transparency. There is no need for using a0poster.cls. You can use a simple article.cls and set the paper size with package geometry. Then you can use xelatex. –  Herbert Jul 3 '13 at 8:40
