图像上的镜像淡入淡出效果

Question

我希望你们能帮助我。我尝试在图像上创建淡入淡出镜像效果。到目前为止，它正在工作，但我希望镜像已经处于半透明（可调）状态。

\documentclass{article}
\usepackage{tikz}
\usepackage{xcolor}
\usepackage{graphicx}
\usetikzlibrary{shadows,fadings}

\begin{document}
\pagecolor{black}

\begin{tikzpicture}[remember picture, overlay]



\def\nodeshadowed[#1]#2;{\node[scale=1,above,#1]{#2};\node[scale=1,
    above,#1,yscale=-1, outer sep=5pt, scope fading=south, opacity=0.3]{#2};}

  \nodeshadowed [at={( 6,-7  )}] {\fbox{\includegraphics[height=0.5\textheight]{ente.jpg}}};
  \end{tikzpicture}
\end{document}

Answer 1

我不确定这是否意味着，但定义淡入淡出样式，例如middle，将提供淡入淡出到中间的效果。请注意，由于镜像top和bottom是反转的。

\documentclass{article}
\usepackage{tikz}
\usepackage{xcolor}
\usepackage{graphicx}
\usetikzlibrary{shadows,fadings}

\begin{document}
\pagecolor{black}

\tikzfading[name=middle,
top color=transparent!0, %completely faded out
bottom color=transparent!100, % use original colour
middle color=transparent!100]

\begin{tikzpicture}[remember picture, overlay]



\def\nodeshadowed[#1]#2;{%
  \node[scale=1,above,#1]{#2};
  \node[scale=1,above,#1,yscale=-1, outer sep=5pt,scope fading=middle, opacity=0.3]{#2};}
  \nodeshadowed [at={( 6,-7  )}] {\fbox{\includegraphics[height=0.5\textheight]{ente.jpg}}};
  \end{tikzpicture}
\end{document}
