如何设置背景图片的不透明度并在右侧/左侧制作两行长文本？

Question

我的书有问题。

（1）左右两侧的文字太长，如何分成两行？

（2）只有玫瑰背景图片的不透明度无法改为 0.2。该如何更改？

这是我的代码。

\documentclass[a4paper,twoside,12pt]{book}
\usepackage[margin=3cm]{geometry}
\usepackage{graphicx, rotating}
\usepackage[svgnames]{xcolor}
\usepackage{tikz}
\usepackage{eso-pic, ifoddpage, transparent}
\usepackage{lipsum,background}

\backgroundsetup{
    scale=1,
    color=black,
    opacity=0.2,
    angle=0,
    contents={%
        \includegraphics[width=15cm,height=15cm,keepaspectratio]{rose.jpg}
    }%
}

\AddToShipoutPictureBG{\checkoddpage\ifoddpage
\AtPageLowerLeft{\hspace*{\dimexpr\paperwidth-2.4cm}
\rotatebox{90}{\makebox[\paperheight]{\textcolor{Red!70}{\small\textbf{This book is used for practicum of the Numerical Ordinary Differential Equation Mathematics Department. Please don't copy, upload, or sell this book.}}}}}%
\else\AtPageUpperLeft{\hspace*{1.8cm} \rotatebox{-90}{\makebox[\paperheight]{\textcolor{SteelBlue!70}{\small\textbf{This book is used for practicum of the Numerical Ordinary Differential Equation Mathematics Department. Please don't copy, upload, or sell this book.}}}}}\fi%
}%

\begin{document}
    \chapter{ONE}
    \section{ABC}
\lipsum

\newpage
\section{DEF}
\lipsum

\newpage
\section{GHI}
\lipsum
\end{document}

如何解决？

Answer 1

（1）对于您上一个问题的回答，如果文本太长，会自动将其分成两行。

（2）图片可以作为节点添加[opacity=...]
