Returns the form’s scaling factor.
property ScaleFactor: TdxScaleFactor read;
The current scale factor.
This property value changes every time your application accepts the
WM_DPICHANGED system message. You can use the
ScaleFactor property to identify the scaling factor’s numerator and denominator values applied to all DevExpress controls on the form. This property is particularly useful if you need to scale the custom paint geometric shapes by calling the ScaleFactor.Apply function.
