You mean compared to the preview?
In drawing it does exactly two pixels for me, as well as 3 and 4 does exactly that pixel count.

However I know openCV line is not perfect, some times it does more or less 1 pixel than selected, this is a issue from openCV that I can't resolve. Currently UVtools does some kind of compensation but not always match the selected pixels count

yes just compared to the preview its off, the drawn pixels are aligned correctly

Yes, I know about that, is not easy to make it right, they are two different draw engines and even with offset to make it on correct place it will displacement in some cases
