How to renderTexture->getData()?

cocos2d-x C++
#1

Currently I need to write:

unsigned char* data = renderTexture->newImage()->getData();

But this works very slow and processor loads gets crazy even on iPhone 6.

How can I effectively getData() from renderTexture?

#2

and you are testing on iPhone 6 hardware or using an emulator?

@zhangxm do you have any thoughts here?

#3

Any more codes about the usage? And what’s the device you tested on?

I just created default renderTexture with size of getFrameSize, full screen size and visited\rendered this.
Nothing special just typical usage of renderTexture. And so when tried to getData(); from it - processor loads was very high bellow 90%. Tested on iPhone 6.
