I would like to write automated tests at various dpi settings; also I would like to change the dpi during the test. Changing the dpi of the machine running the tests is cumbersome and fragile, so I would prefer to achieve the same effect inside the test process. Is there a way?
I was thinking of using reflection to call HwndSource.ChangeDpi. Is that a viable solution? Or does something in wpf's guts call native functions that will still be reporting the real dpi?
Which value should I pass as
suggestedRect
to the constructor of HwndDpiChangedEventArgs ?Beta Was this translation helpful? Give feedback.
