Image autoscaling according to design resolution size

I’m using setDesignResolutionSize to make the game resolution agnostic. For some reason the images are creating “as is”. After image loading I need to rescale them manually, i.e., something like: sprite->setScale(CCDirector::sharedDirector()->getContentScaleFactor()). Is this is a by design behavior or do I have a smarter way of scaling the images?

Thanks!

If you use setDesignResolutionSize then images should be scaled automatically when needed http://www.cocos2d-x.org/projects/cocos2d-x/wiki/Multi_resolution_support
