Can anyone who is well versed in tikz draw help me to include a small inset inside a larger image? (The inset - image 2 - is a "zoomed in" of the smaller inset in image 1 ).
I couldn't do that in tikz, then I tried to do this manually using gimp software (see image below) and lost image quality in the inset (I had to scale the image 2 within a frame I drew and connected two ends (right-north and left-south) to a small inset in image 1. Unfortunately the smaller inset (where the green contours are embedded) in image 1 is not visible because of the color black I used to draw the lines.
Thank you very much!
