Yves, Boris,
i'd like to know if there's a way to define some spaces in the screen where you can decide to have some picture passing in. Hard to explain but let me try :
- Suppose you have a projection on a screen.You put a video full screen which is your background.
- then on a second layer, you have a media (picture or movie)with no alpha, simply on a 4/3 format or whatever. Is there's a way to imagine a module that can define some virtual shapes in which can appear you media (second layer in the example above), and out of this define shape, it doesn't appear anymore, so that you can still see you background layer? A kind of virtual mask in fact.
Am I clear enough?
Thanx !
