Method PhysicalScreen():getScaleFactor() Foundation
Returns the scale factor.
:getScaleFactor() --> nScaleFactor
A numeric value with the scale factor.
The method :getScaleFactor() returns the scale factor set for a physical screen. The scale factor is used for converting between points and pixel units and defines the DPI (dots per Inch) used with the screen. A scale factor of 1.0 means that one point corresponds to one device pixel. In this case, the pixel resolution is roughly equivalent to 96 DPI.
Compatibility note: Xbase Part-based applications normally use a fixed unit system. On physical screens using a different scale factor (DPI), the operating system automatically scales the application UI to the user's preferred scale. For this reason, the value contained in :scaleFactor normally is 1.0.
