With regards to this two questions Tikz - three pictures in two pages in landscape mode and Tikz - highlight text in an image, I struggle to put the given solutions together (which work otherwise fine for me) to highlight a part in picture A.
The context is that I have two pages (A4 in landscape mode) with three pictures on them, while one in the middle spane over both pages. Now I would like to highlight a part of the first picture, but fail to highlighted the desired part and have the rest reduced to an opaque black.
This is my code:
\documentclass{article}
\usepackage[margin=0cm, top=0cm, bottom=0cm, outer=0cm, inner=0cm, landscape, a4paper]{geometry}
\pagestyle{empty}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[overlay,remember picture]
\pgfmathsetmacro{\mywidth}{2*\paperwidth/3-1cm} % kept local
\node at ([xshift=-\paperwidth/6-1cm]current page.center){%
\includegraphics[width=\mywidth pt,height=\paperheight]{example-image-a}};
\begin{scope}[x={(image.south east)},y={(image.north west)}]
\fill[even odd rule,opacity=0.4]
(0.11,0.4) -- (0.37,0.404) -- (0.37,0.414) -- (0.11,0.41) -- cycle
(0,0) rectangle (1,1);
\end{scope}
\node at (current page.east){%
\includegraphics[width=\mywidth pt,height=\paperheight]{example-image-b}};
\end{tikzpicture}
~
\clearpage
\begin{tikzpicture}[overlay,remember picture]
\pgfmathsetmacro{\mywidth}{2*\paperwidth/3-1cm} % kept local
\node (image) at ([xshift=\paperwidth/6+1cm]current page.center){%
\includegraphics[width=\mywidth pt,height=\paperheight]{example-image-c}};
\node at (current page.west){%
\includegraphics[width=\mywidth pt,height=\paperheight]{example-image-b}};
\end{tikzpicture}
\end{document}
I presume that I do not manage to highlight parts of the image as it is not in a minipage environment. What can I do?
