Highlight regions in an image with CLI
I have an image (a photo) and I want to highlight certain parts of this. I want to do this from the CLI.

I am planning to store the pixel coordinates of polygon vertices in a file, and when I run a script, a new image should be applied with the polygons highlighted. I am going to be making a lot of tweaks to the file, which is why I want the coordinates of highlighted areas in a text file.

How can I accomplish this? I am comfortable programming if that is the easiest option.
