In beamer, I like to place a background image in all my slides. So I could use this:
\usebackgroundtemplate{
\tikz[overlay,remember picture] \node[opacity=0.3, at=(current page.center)] {
\includegraphics[height=\paperheight,width=\paperwidth]{background.png}};
}
However, to put the background image at the right-bottom corner, what should I do? I guess I should change some how "current page.center" to something like "current page.south east". But, I want to match the right-bottom corner of the image file with the right-bottom corner of the slides.
anchor=south east
together withat=(current page.south east)
. Moreover, you'd probably also want to setinner sep=0
to avoid unnecessary white spaces.
