How I can modify the solution by @Jake on the following question; I want just to be able to rotate the subfigures for 90 degrees.

How to create magnified subfigures and corresponding boxes for portions of a large image

Edit:

Here is @Jake's whole implementation:

Thank you!

  • Please provide a Minimal Working Example. Otherwise, it is difficult to know how to help you. Depending on the packages and methods used, some optional argument could be angle=90 or rotate=90, to obtain the rotated image. – BambOo Mar 23 '18 at 9:00
  • @BambOo , I'm using the whole implementation from answer of @Jake in the link. I don't know if it's OK to copy and paste it here again - I just have my own Figure. I'm receiving the magnified subfigures but now I need to rate them. I already have tried so many times and in several places to write angle=90 or rotate=90but I couldn't find where I should write it to rotate only the subfigures :( – user4712458 Mar 23 '18 at 9:06
  • @BambOo , I added his whole implementation; see my Edit. – user4712458 Mar 23 '18 at 9:11

I played a bit with @Jake's magnificent code, but despite some partial successes I gave up. On the other hand, if you only want to rotate some zoomed area, then you just go with section 68.3 of the pgfmanual. (The figure is taken from @Jake's magnificent code.)

\documentclass{article}
\usepackage{graphicx}
\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{spy,calc}
\begin{document}

\begin{tikzpicture}
[spy using outlines={lens={scale=3,rotate=45}, size=4cm, connect spies}]
\node at (0,0) {\includegraphics[width=8cm]{gallery}};
  \spy [red] on (-0.9,2) in node at (8,1.25);
\end{tikzpicture}

\end{document}

enter image description here

Clearly, this does not look anywhere as nice as @Jake's code, but it is perhaps easier to adjust to your needs.

  • I didn't try this option, as I liked and I just took the solution from Jake, which one I was trying desperately to understand how to "modify" for my purpose. But, now even this one works fine, just I'm showing a single magnified subfigure, which is still OK. Thank u so much!!! – user4712458 Mar 23 '18 at 23:00
