I am trying to find a c++ library/tool that will let me make a window and change pixel colors (preferably just from black to white), using coordinates, I have been looking, but ended up just going in circles, I am using linux with the kde desktop. the window would be purely an output, with inputs from execution on the cli. And I suppose that "pixels" would not be the right term, I want to have blocks in a window that I can assign a value to. Just making a grid in the cli to output white blocks of text to could also work, but I would prefer a window related solution
Thank you for your time.
