CCSprite scale interpolation

Hello, I need to scale sprites in my app.
Looks like, that scale is using linear interpolation. Is there a way to make engine scale my sprites using cubic interpolation?

I tried to scale my image to same size in GIMP setting “interpolation = none” and got the same visual result as in cocos2d-x
Looks like, my sprites in cocos2d-x are scaled without any interpolation…

Any suggestions?
