标题页右上角的背景图像

Question

我正在尝试在标题页的右上角添加一个背景图像，顶部和右侧的边距为 1 厘米。

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}

\title{Test}
\author{Test}
\date{\today}

\usepackage{eso-pic}
\usepackage[demo]{graphicx}

\providecommand*\LenToUnit[1]{#1\@gobble}

\newcommand\AtPageUpperRight[1]{\AtPageUpperLeft{
\put(\LenToUnit{0.5\paperwidth},\LenToUnit{-1cm}){#1}}
}

\begin{document}

\AddToShipoutPictureBG*{
 \AtPageUpperRight{\raisebox{-\height}{\includegraphics{logo.pdf}}}
}

\maketitle

\end{document}

可以将图像右对齐吗？
