Trying to insert a background image via TikZ results in extra white-space around the corners












5















I am trying to insert a background image in my beamer template as follows:



documentclass[10pt,c,aspectratio=169,a4paper]{beamer}
usepackage{tikz}


setbeamertemplate{background}{
begin{tikzpicture}%
node {includegraphics[width=paperwidth,height=paperheight,keepaspectratio]{example-image-a}};
end{tikzpicture}
}

begin{document}

section{Introduction}

begin{frame}

end{frame}
end{document}


this results in



enter image description here



as you can see, due to some sort of bounding box around the inserted image, there is a space from the north-west corner of the image in (x-y). However, I would like to position the image in the starting at the north-west corner.
