Is it possible to know when a user has enabled the windows magnifier (win+/-) and what zoom level (percentage) they have set ?

Hi everyone,

As is written in the question I would like to know if an app I'd build would be able to get such information as the magnifier being enabled or not and if it is, how it has been set (mostly the zoom level/percentage).

Additionaly, if the answer to the first question is positive, would there be a way to get the same information if the user isn't using the built-in magnifier but rather using another magnifier app (e.g. ZoomText). Assuming they used the provided windows Magnification API to build their app, which may not be the case.

I have been searching a bit but haven't been able to find any solid information on this.

Thank you
