cocos2d(-x): the mode of pictures intersection?

As the picture blew shows, two pictures insert each other. The way I can think is using ccBlendFunc function, but I am not sure. So, Is there any way to do that with cocos2d(x)?
Thanks for any help

Oh, what a dust!!!
Actually I have this question too.What is solution?

P.M:
Instead of redundancy and creating new topic I preferred to use an older one!
