封底的不透明度效果

这是一段旨在放在书封底的段落。我希望为其添加不透明效果，因为它位于封底背景图片之上。如何为该段落添加不透明效果？ 封底上方的图片

以下是tcolorbox允许直接设置所需边距的解决方案。我在代码中标记了选项：

\documentclass[10pt]{standalone}
\usepackage[skins]{tcolorbox}
\usepackage{mathrsfs}
\usetikzlibrary{arrows}
\pagestyle{empty}

\begin{document}
\thispagestyle{empty}%
\begin{tcolorbox}[
  enhanced,size=minimal,sharp corners,
  text fill,            % only, if \vfill is to be used
  width       = 210mm,  % paper width
  height      = 297mm,  % paper height
  leftrule    = 20mm,   % outer margin
  rightrule   = 20mm,   % outer margin
  toprule     = 25mm,   % outer margin
  bottomrule  = 25mm,   % outer margin
  left        = 15mm,   % inner margin
  right       = 15mm,   % inner margin
  top         = 20mm,   % inner margin
  bottom      = 20mm,   % inner margin
  frame style = {fill overzoom image=goldshade.png},  % background image
  opacityback = 0.5,    % transparency
  colback     = cyan!22,
]

更新：

原始问题使用了standalone类。通过一些小的修改，您可以使用类似 的类获得与页面相同的东西article。

以下示例还包含

frame style = {fill plain image*={scale=3}{goldshade.png}}

显示包含可任意缩放的背景图像，正如 OP 在评论中所要求的那样。

\documentclass[10pt]{article}
\usepackage[skins,breakable]{tcolorbox}
\usepackage{mathrsfs,lipsum}
\usetikzlibrary{arrows}

\begin{document}

\lipsum[1-20]

\begin{tcolorbox}[
  enhanced,size=minimal,sharp corners,
  spread,
  phantom=\thispagestyle{empty},
  text fill,            % only, if \vfill is to be used
  leftrule    = 20mm,   % outer margin
  rightrule   = 20mm,   % outer margin
  toprule     = 25mm,   % outer margin
  bottomrule  = 25mm,   % outer margin

  right       = 15mm,   % inner margin
  top         = 20mm,   % inner margin
  bottom      = 20mm,   % inner margin
  frame style = {fill plain image*={scale=3}{goldshade.png}},  % background image

您可以将应用opacity=到文本：

代码：

\documentclass[10pt]{article}
\usepackage{graphicx}
\usepackage{pgf,tikz}
\usepackage{mathrsfs}
\usetikzlibrary{arrows}
\usepackage{showframe}
\pagestyle{empty}

\begin{document}
\noindent
\begin{tikzpicture}
\node[anchor=south,inner sep=0] (A) at (0,0) 
    {\includegraphics[width=\linewidth]{../images/EiffelWide.jpg}};

\node[text width=10cm,align=left, anchor=south, text opacity=0.9, 
    shift={(0.0cm,0.75cm)}
] at (0,0) 
{\noindent\fcolorbox{black}{cyan!22}{%

答案3

与 Peter Grill 的回答非常相似，只是fill opacity。 tcolorbox 将继承节点的填充不透明度。

\documentclass[10pt]{standalone}
\usepackage{pgf,tikz}
\usepackage{mathrsfs}
\usetikzlibrary{arrows}
\pagestyle{empty}

\begin{document}
\thispagestyle{empty}

\begin{tikzpicture}
\node[rotate=90] {\includegraphics[scale=1.5]{example-image-a}};
\node[text width=12cm,align=left,fill opacity=0.7] {\noindent\fcolorbox{black}{cyan!22}{%
\begin{minipage}{\dimexpr1.00733\textwidth-2\fboxrule-2\fboxsep\relax}

\vspace*{4cm}
