Hello,  
How can you write a program for multiple devices? I mean devices with different resolutions. I found out there is a thing called PPI but couln’t really find a way to implement it.  
Lets say I have an object in flash with dimensions 1000x1000.  
In one of the devices I would like it to appear 500_500, in another one 400_400.  
Any suggestions?  
Thank you in advance.  
Edit: Just to make it clear, my aim is to use one flash file and get it to work on different devices without recoding.
