I want to use a little pdf picture as a logo in every page of my file, exactly in the top of every page, no margin on top, no margin on left and right side, how to make it?
I use below simple settings, but obviously there are margins...
\usepackage{fancyhdr}
\setlength{\headheight}{55.2pt}
\setlength{\headwidth}{\textwidth}
\fancyhead[C]{\includegraphics[height=1.53in]{logo.pdf}}
\pagestyle{fancyplain}
