using `warpAffine` with custom matrix respecting pixel coordinate flavors would be a workaround. notice that I use INTER_LINEAR so you can see roughly where sampling is done. INTER_LINEAR appears to...

It's dead, sadly. `mss` isn't as dead, but also dead.

OpenCV, in python, uses numpy arrays. I don't quite know what you're doing there but `d.capture_output.backend` is not a numpy array, yet you pass it to an opencv function as...

if you need to handle overlap, i.e. not be bothered by it, there's the "thumbnail" API from the DWM. gives you a full resolution picture of any window. I don't...

> self.__intermediaryImage = self.get_screenshot() > self.__lock.acquire() > self.__newestImage = self.__intermediaryImage > self.__lock.release() that is pointless, and so is the locking in `GetLatestImage`. python variables are references. the assignment sets a...
