But what's the logic behind it any why another y-loop?
The rgbToTextFormat() is heavy already, this could take a long time to process now that there are two 2-dimensional loops calling functions heavily.

I agree. There is no point of another y-loop.

like if there's front use the front and skip the background?

Is it better now?
