How do I scale up/down based on window size?

Hi,

I'm trying to achieve auto scale up/down based on the window size.

Irrespective of the aspect ratio, If I increase the layout size it should scale down to fit the view and it I decrease the layout size it should scale up.

Something like this but not exactly the same.

This video demos only in 1:1 aspect ratio but when try in 16:9 it shows black screen, it should not happen. The maximum width or height a user can see is 1024 and irrespective of the layout size I should be able to see only the background but not any black screen.

Here is the c3 file

Any help would appreciated.

Thanks in advance.

Have you tried Scale Outer mode? See this example:

dropbox.com/s/t26uee766dyqdss/TestLayoutScale.c3p

Or do you need to limit the minimum scale at 100%? I.e. - if the window is bigger than 1024x1024, then the layout is scaled up, but if it's smaller, then the layout is cropped?

Thanks for your response.

The window view should not go beyond 1024 on either height or width. If I decrease the window size, the layout zoom out (should not crop) to fit to 1024 on either width or heigth likewise if I increase the window size, the layout should zoom in to fit to 1024 on either width or heigth.

I tired using the scale outer mode it goes beyond 1024.

I will check your c3p file now. Thanks. :D

dop2000 Scale Inner works well. Thanks for the tip. :D
