How to zoom with CCCamera

HI,
i would like to make a zoom in/out inside a 2d sprite with camera, in order to make an effect, i have looked to the Camera 3d test , but it very complicated for me since it includes many things.
Please help me.
I use cocos2d-x V3.3 .
Thanks.

Do you want to zoom a single sprite or zoom into the complete scene?

No, single sprite, because i’m developing an interactive book and i divided my scene into two parts, one for the text in the second for the images of the story.

Then why you just don’t scale the sprite? That’s what OpenGL does behind the scenes when zooming anyway.
