Hello guys I have a PNG picture. and i would like to zoom into a portion of it for the reader to see the changes made by my algorithm. How can i do this. I have MWE below:

\documentclass[margin=0.1cm] {standalone}
\usepackage[left=1in,right=1in,top=1in,bottom=1in]{geometry} 
\usepackage{graphicx}
\usepackage[version=0.96]{pgf}
\begin{document}

\insertimage{example-image-a}


\end{document}

  • Once the image is trimmed you can zoom it by making the graphic larger (scale=2 or height=..,width=..). This is more or less what the solution below also does, but then using an additional package. – Marijn May 19 '21 at 18:04

\newsavebox\myzoom
\begin{document}
\sbox4{\includegraphics{example-image-a}}
\savebox\myzoom{\clipbox{.5\wd4{} .25\ht4{} .3\wd4{} .55\ht4}{\copy4}}
\scalebox{5}{\usebox\myzoom}
vs.
\copy4
\end{document}
