Controlling lights with reading pixels

[heymcfly]

This is my first post so please be gentle 😁

There was a thread on reddit about a month ago where someone controlled their lights based on their healths.
I hooked up my character'''s HP bar to a smart light : classicwow

I did this myself using Lua via wowqr and a small c# app and it works great but I have some questions.

1. Since this isn't real "botting", is reading from the screen something wow can ban you for?
2. I tried using single-pixel mapping but I found that there's a problem with UI scaling - one Lua pixel is like a 3x3 pixel when mapped to the screen. Is there a way to determine pixel scaling on the C# side?
