Flex defaults to NO_SCALE. In Flex, the SystemManager is the root. You can play with setting systemManager.scaleX and systemManager.scaleY.
IIRC, there are several factors to controlling stage scale: the SWF dimensions stored in the SWF header and set in the MXML application tag and the actual size of the window. In AIR, you can control the size of the window from code AIR also has the requestedDisplayResolution descriptor tag. If the SWF size matches the Window size it should scale more predictably. I haven’t tried it with AIR and Retina. https://blogs.adobe.com/aharui/2008/01/flex_and_scalemodes.html On 2/15/15, 11:03 PM, "Deepak MS" <[email protected]> wrote: >Hi Alex, >Just looked at it. > >There are 4 different values it can take.
