zoom in object QPixmap

I need to ask an object zoom QPixmap.

Any idea how?

Thanks

First, your question in incoherent. If the question was any more complex it'd be good to revise it heavily so it's readable.

Second, I believe you asked this question.
You probably should've looked at that link (right above the title as you wrote the thread) before posting.

That said, I'm unsure if this is what you're looking for, but this is the closest thing to "zooming" you'll find. You'll have to track how much you've "zoomed" in and such yourself.
