Should I use JAI?

I would like develop program with a lot of image processing. I would like to use Java, and JAI, but it seems to me, that Jai is ol开发者_运维技巧d and no longer evolve? (http://java.sun.com/javase/technologies/desktop/media/jai/)

I wonder, is it better choice to use QT and c++?

Two main pros which I am looking for is: cross platform code and good learning opportunity.

If you're wanting to do image processing, then what JAI did 3 years ago will be sufficient for the mathematical base of what you want to do now. New image formats etc would probably not require new updates to JAI.

I just can't think of anything that you'd need to add once you've got the basic operations - it's the application on top that's going to get new features.

Now how you get your graphical ideas into an Image that you can then process... awt, swing, Java FX...
